Detailed Description
The application is described in further detail below with reference to fig. 1-8.
In order to facilitate the explanation of the scheme, the mechanism of the generation of the high-voltage cable sheath circulation and the damage caused by the abnormality of the high-voltage cable sheath circulation are explained first.
Mechanism for generating high-voltage cable sheath circulation: when the high-voltage single-core cable core passes through alternating current, an induced magnetic field is generated around the cable core, the intensity of the induced magnetic field is in direct proportion to the current passing through the cable core, an induced voltage is generated on the metal sheath due to the eddy current effect, and the magnitude of the induced voltage is related to the core current, the cable length and the laying mode, the arrangement mode, the distance and the like of surrounding loops.
When the cable outer sheath is damaged, suffers overvoltage or suffers from asymmetric short circuit fault, the metal sheath is grounded at multiple points, namely a loop is formed among the metal sheath, the grounding wire and the grounding system, so that induced circulation is generated, the current can reach 50% -95% of the core current, the metal sheath or the armor layer is heated, a large amount of electric energy is lost, insulation aging of the cable is accelerated, and even breakdown of the weak part of the cable insulation is caused.
Hazard of high voltage cable sheath circulation abnormality: (1) The current-carrying capacity of the cable line is directly influenced by the abnormal circulation of the cable sheath, the influence of the abnormal circulation of the cable sheath on the current-carrying capacity can reach 30% -40%, and when the abnormal circulation of the cable sheath is caused, the maximum allowable load of the cable line cannot exceed 60% of the rated current-carrying capacity.
(2) The cable sheath circulation is abnormal, so that the cable loss generates heat, the insulation is at a local high temperature, the insulation aging is accelerated, and the service life of the cable is reduced.
(3) The cable sheath circulation is abnormal, so that the cable sheath is possibly damaged, the multipoint grounding phenomenon is caused, the metal sheath is easily corroded due to the damage of the outer sheath, the probability of main insulation aging is increased, partial discharge is easily induced, and the safety operation of a cable line is greatly threatened.
The embodiment of the application discloses a cable operation monitoring method, which is shown in fig. 1 and comprises the following steps:
s101, acquiring an operation signal;
s102, analyzing the operation signals to generate corresponding target detection items;
s103, judging whether the target detection item meets a preset safety standard or not;
s104, if the safety standard does not accord with the preset safety standard, acquiring a corresponding abnormal detection item;
s105, judging the abnormal type of the abnormal detection item according to a preset monitoring standard;
s106, if the abnormality type is spontaneous abnormality, acquiring and analyzing corresponding abnormal data, and generating corresponding induction factors as judgment results;
s107, if the abnormality type is external abnormality, acquiring corresponding environmental factors as a judgment result;
s108, generating a corresponding monitoring report according to the judging result.
The operation signals in the steps S101 to S102 refer to all operation signals collected by the cable during normal operation; the target detection items refer to items to be detected corresponding to various operation signals.
In practical application, the operation and maintenance of the cable line needs to pay attention to all operation signals in the operation process of the cable line at all times, and the state change of the cable in the operation process can be known through the operation signals.
For example, in general, a load operation signal of a cable line defines a maximum current according to a sectional area of a cable conductor, an insulation type, and the like, and a load current of the cable line, a sheath temperature of the cable, and the like are measured by various meters as main load monitoring measures to prevent the cable from exceeding an allowable maximum temperature and shortening a life of the cable, so that the load operation signal is analyzed to generate a corresponding load current detection term.
Step S103 to step S104 are preset safety standards, wherein the preset safety standards refer to the safety standards corresponding to all target detection items in the cable operation process; the real-time monitoring data refers to real-time updating monitoring data of each target detection item; the abnormal detection item refers to a detection item which does not meet a preset safety standard in the target detection items.
For example, when measuring the temperature of the buried cable, the soil temperature of the same section without other heat sources should be measured, so that the corresponding preset safety standard is obtained according to the cable temperature detection item: in any case, the soil temperature of the same depth of other places of the local section is not more than 10 ℃, the soil temperature of the same depth of the detected cable is 20 ℃, the cable temperature displayed in the cable temperature detection item is 25 ℃, and if the cable temperature detection item is judged to meet the corresponding preset safety standard, the real-time monitoring data of the cable temperature are continuously obtained.
For another example, when the soil temperature of the same depth of the detected cable is 20 ℃, and the cable temperature displayed in the cable temperature detection item is 35 ℃, the cable temperature detection item is judged to be not in accordance with the corresponding preset safety standard, and the cable temperature detection item is obtained and calibrated to be an abnormal detection item.
The preset monitoring criteria in step S105 to step S107 refer to the criteria that each item of monitoring data should conform to when the cable is running; spontaneous abnormality is the condition that the cable is not affected by the outside and is abnormal; the induction factors refer to related induction factors for generating abnormal data, and the external abnormality refers to abnormal conditions of the cable caused by the influence of external individual conditions; the environmental factor refers to an external environmental condition factor in the process of operating the cable.
In practical application, no matter spontaneous abnormality or external abnormality, the circulation abnormality of the metal sheath of the cable is likely to be caused, the rated current-carrying capacity of the cable is further influenced, the direct grounding of the two ends of the sheath is taken as an example, in all grounding modes of the cable sheath, the circulation of the direct grounding of the two ends of the metal sheath is the most serious, and the influence on the current-carrying capacity is the greatest.
The monitoring report in step S108 refers to a summary of analysis data that results in the generation of various anomaly types.
For example, when the high-voltage single-core cable is normally operated, besides circulation current, there are capacitance current and unbalanced current of the ground network of two grounding points of the sheath in the cable sheath, so that the measured current is theoretically larger than the actual circulation current value, and therefore the abnormality type belongs to spontaneous abnormality, and since the abnormality is not overcome under normal circumstances, in the case that the abnormality occurs that the measured value of the current is larger than the actual circulation current value, the system outputs a relevant evoked factor monitoring report about the capacitance current and the unbalanced current of the ground network of two grounding points of the sheath.
According to the cable operation monitoring method, the operation signals in the cable operation process are analyzed to generate the corresponding target detection items, whether the target detection items meet the corresponding preset safety standards or not is judged immediately, preliminary safety judgment can be conducted on the target detection items, if the corresponding preset safety standards are not met, the abnormal types of abnormal detection items in the target detection items are further judged, spontaneous abnormality in the cable or external abnormality outside the cable is further obtained, analysis and judgment are conducted on line abnormality data or corresponding external environment factors in the cable operation process, corresponding judgment results are obtained, and a monitoring report is generated, and due to the fact that the abnormal target detection items are analyzed in a classified mode, the monitoring effect in the cable operation process is improved.
In one implementation manner of the present embodiment, as shown in fig. 2, the anomaly data includes cable circulation data, and step S106, that is, if the anomaly type is spontaneous anomaly, acquires and analyzes the corresponding anomaly data, and generates the corresponding induction factor as the determination result includes the following steps:
s201, acquiring a corresponding circulation value according to cable circulation data;
s202, judging whether the circulation current value exceeds a preset circulation threshold value;
s203, if the circulating current value exceeds a preset circulating current threshold value, a corresponding grounding mode is obtained;
s204, judging whether the grounding mode meets a preset grounding standard or not;
s205, if the grounding mode does not accord with the preset grounding standard, acquiring and generating corresponding induction factors according to the current connection mode as a judgment result;
s206, if the grounding mode meets the preset grounding standard, acquiring and analyzing the cable wiring information, and generating corresponding induction factors as a judging result.
In practical application, the cable loop data refers to the loop data of the high-voltage cable sheath; the circulation value refers to the circulation value in the cable sheath; the preset circulation threshold value refers to a normal circulation threshold value of the high-voltage cable sheath; the grounding mode refers to a mode that cable lines are connected with each other in a crossing mode; the preset grounding standard refers to the grounding standard when the cable lines are connected with each other in a crossing way; the current connection mode refers to the current connection mode of the cable line.
It should be noted that, the high-voltage cable generally adopts the grounding modes of directly grounding two ends of the metal sheath, directly grounding one end of the metal sheath, grounding the other end of the metal sheath with protection, and cross-connecting the metal sheath. In operation, the cross-connection transposition connection must be correct, the interconnection transposition modes in the two grounding boxes in one cross-connection section must be consistent, if the two cross-connection transposition are opposite, the circulation in the cable sheath will be large, which is equivalent to the circulation in direct grounding, and the load current value in the cable core can be reached to the maximum.
For example, according to the preset grounding standard, the high-voltage cable adopts the metal sheath cross-connection grounding, the metal sheath cross-connection transposition modes are required to be consistent, the current grounding mode of the high-voltage cable is the cross-connection grounding through detection, but the interconnection transposition modes in two grounding boxes in one cross-connection section are inconsistent, the grounding mode can be judged to be inconsistent with the corresponding preset grounding standard, and the corresponding induction factors generated by the current metal sheath cross-connection transposition modes are further obtained to serve as judgment results.
For example, the grounding mode of the current high-voltage cable is the cross interconnection grounding mode, and the interconnection transposition modes in the two grounding boxes in one cross interconnection section are consistent, so that the grounding mode can be judged to be consistent with the corresponding preset grounding standard, and the wiring information of the cable is further acquired and analyzed.
According to the cable operation monitoring method provided by the embodiment, whether the corresponding circulating current value in the cable circulating current data exceeds the corresponding preset circulating current threshold value is judged, the safety of the cable circulating current data can be primarily qualified, the corresponding grounding mode of the cable is further checked, the current connection mode which does not meet the preset grounding standard is obtained to be used as an induction factor of the cable circulating current data abnormality, and therefore the monitoring efficiency of the grounding mode of the cable circulating current data is improved when the cable circulating current data is abnormal.
In one implementation manner of the present embodiment, as shown in fig. 3, step S206, that is, if the grounding mode meets the preset grounding standard, acquires and analyzes the cable connection information, and generates the corresponding evoked factor as the determination result includes the following steps:
s301, if the grounding mode accords with a preset grounding standard, acquiring a corresponding current wiring mode according to the cable wiring information;
s302, judging whether the current wiring mode meets the corresponding wiring standard;
s303, if the current wiring mode does not accord with the corresponding wiring standard, acquiring a corresponding abnormal wiring item;
s304, establishing a corresponding abnormal circulation model according to the abnormal wiring item;
s305, acquiring a corresponding target circulation value according to the abnormal circulation model;
S306, selecting an abnormal wiring item corresponding to the maximum target loop current value, and generating a corresponding induction factor as a judgment result.
In practical application, the current wiring mode refers to the wiring mode of a circuit when a cable runs; the wiring standard refers to the relevant wiring standard which the cable should meet under the normal operation condition; the abnormal wiring item refers to an abnormal wiring item which does not accord with the corresponding wiring standard in the current wiring mode of the cable line; the abnormal circulation model is a high-voltage cable sheath circulation model established according to the current abnormal wiring item; the target circulation value refers to the circulation value of the cable sheath in the abnormal circulation model.
In practical application, when the outgoing line of the insulated connector is connected to the coaxial cable, the wiring error can also greatly increase the circulation of the metal sheath, in order to ensure the correctness of the cross circulation transposition of the cable, besides the wiring of the cross interconnection box, the power supply side and the load side wiring of the coaxial cable from the three-phase insulated connector to the grounding box must be ensured to be all correct, otherwise, the failure of the cross interconnection transposition can also be caused, and the circulation of the metal sheath is greatly increased.
For example, according to the wiring standard of the cable, the grounding mode of the grounding line of the single-core cable line is as follows: the midpoint of the shield is grounded: when the length of the line is 1000-1400 meters, a midpoint grounding mode is adopted, (1) the shielding layers are directly grounded at the middle position of the line, the shielding layers of the terminal heads at the two ends of the cable are grounded through the protective layer protector, and a direct through head is generally arranged at the middle grounding point; (2) An insulating connector is arranged at the midpoint of the line, the insulating connector breaks the cable shield, two ends of the shield are respectively grounded through a protective layer protector, and two cable terminal shields are directly grounded.
The length of the current cable line is detected to be 1200 meters, a middle point grounding mode is adopted, the middle position of the line is directly grounded by the shielding layer, the shielding layer of the terminal at one end of the cable is grounded by the protective layer protector, and a direct through head is not arranged at the middle grounding point. And judging whether the corresponding wiring standard is not met, acquiring a cable end shielding layer grounding abnormal item and a through head abnormal item, establishing a corresponding abnormal circulation simulation model according to the cable end shielding layer grounding abnormal item and the through head abnormal item, respectively obtaining respective corresponding target circulation values of the cable end shielding layer grounding abnormal item and the through head abnormal item, wherein the corresponding target circulation value of the cable end shielding layer grounding abnormal item is larger than the corresponding target circulation value of the through head abnormal item, and selecting the cable end shielding layer grounding abnormal item to generate a corresponding induction factor as a judgment result.
According to the cable operation monitoring method provided by the embodiment, the wiring mode of the cable is analyzed on the premise that the grounding mode accords with the corresponding standard, an abnormal wiring item which does not accord with the wiring standard is obtained, a corresponding abnormal circulation model is further established according to the abnormal wiring item, the obtained corresponding target circulation value is evaluated, and the abnormal wiring item with the maximum target circulation value is selected as a main induction factor for inducing the cable circulation abnormality, so that the monitoring and investigation effects of the abnormal wiring item in the current wiring mode of the cable are improved.
In one implementation manner of the present embodiment, as shown in fig. 4, step S106, that is, if the anomaly type is spontaneous anomaly, acquires and analyzes the corresponding anomaly data, and generates the corresponding evoked factor as the determination result includes the following steps:
s401, acquiring corresponding material attribute data according to the connection material data;
s402, judging whether the material attribute data meets a preset material standard or not;
s403, if the material attribute data meets the preset material standard, acquiring the working performance of the current connecting material;
s404, judging whether the working performance meets the cable operation condition;
and S405, if the working performance does not meet the cable operation condition, acquiring the working performance and the connection position of the current connection material, and generating corresponding induction factors as a judgment result.
In practical application, the connection material data refers to connection material data of the cable and the joint, jumper wire, grounding box and other parts; the material attribute data refers to attribute information corresponding to the connecting material; the preset material standard is a material attribute standard selected by the connection materials of the cable, the joint, the jumper wire, the grounding box and the like; the cable operation conditions refer to various performance conditions when the cable is in normal operation.
Since the cable is generally connected to the joint, jumper wire, grounding box, etc. by using a metal such as copper and aluminum, poor contact may be caused due to the different conductive properties of the metal materials, and thus, excessive circulation may be caused.
For example, according to preset material standards, the respective standards of the cable joint are: firm and reliable connection, high mechanical strength, corrosion resistance and oxidation resistance, and the material is selected from copper or aluminum.
The copper material selected by the cable joint is detected, and the cable joint is firm and reliable in connection, high in mechanical strength, corrosion-resistant and oxidation-resistant, so that the material attribute data of the cable joint can be judged to accord with the corresponding preset material standard.
The cable connector is further obtained according to the cable operation conditions, the conditions of small connector resistance and good electrical insulation performance are required to be met, and if the electrical insulation performance of the cable connector is detected to be poor, the cable connector can be judged to be not in accordance with the corresponding cable operation conditions, the poor electrical insulation performance and the connection position of the cable connector on a cable line are obtained, and corresponding induction factors are generated as judgment results.
According to the cable operation monitoring method, the insulation connection equipment of which the cable is affected is obtained according to the oxidation data around the cable, whether the insulation performance of the insulation connection equipment meets the preset insulation standard is further judged, if not, the oxidized oxidation degree information of the insulation connection equipment is obtained, and a target oxidation model corresponding to the insulation performance under the current oxidation degree is generated, so that the monitoring and checking effect of the insulation connection equipment of the cable is improved.
In one implementation manner of the present embodiment, as shown in fig. 5, in step S106, if the anomaly type is spontaneous anomaly, corresponding anomaly data is acquired and analyzed, and after generating a corresponding evoked factor as a determination result, the method further includes the following steps:

In actual application, the circuit part refers to the circuit part corresponding to the abnormal data of the cable circuit; the assembly information refers to the installation and assembly information of each part of the cable line; the assembler directory refers to personnel information of the installation and assembly of each part of the cable line.
For example, if the installation and selection materials of the cable joint part in the area A are abnormal, all installation and assembly information of the cable joint in the area A is obtained, the installation and selection work of the cable joint part is further known from the installation and assembly information in the area A to be completed by the king, and directory information of the king assembly personnel is obtained as corresponding feedback information.
According to the cable operation monitoring method provided by the embodiment, when spontaneous abnormality occurs in a cable line, the traceability effect on assembly personnel of the cable line can be improved.
In one implementation manner of the present embodiment, as shown in fig. 6, the environmental factors include oxidation data, and step S107, that is, if the anomaly type is an external anomaly, includes the following steps of:
s601, acquiring corresponding insulating connection equipment according to oxidation data;
s602, judging whether the insulation performance of the insulation successive equipment meets a preset insulation standard;
s603, if the insulation performance of the insulation connection equipment does not meet the preset insulation standard, obtaining oxidation degree information corresponding to the insulation connection equipment;
s604, identifying oxidation degree information according to a preset oxidation standard, and generating a corresponding target oxidation model as a judgment result.
In practical use, the oxidation data refers to the relevant oxidation data of the cable line; the insulation connection equipment refers to relevant insulation equipment to which the cable needs to be connected; the preset insulation standard refers to an insulation standard that the insulation successive device should conform to.
The insulating material is changed in structure and chemical properties by moisture, acid, ozone, nitrogen oxide, etc. in the air, so that the electrical and mechanical properties are lowered. For example, the transformer oil generates organic acid in air due to oxidation, so that dielectric loss is increased, and solid precipitate is formed to block an oil duct, influence convection heat dissipation, raise insulation temperature and reduce insulation performance.
For example, according to a preset insulation standard, the crosslinked polyethylene insulated pvc jacketed power cable has an insulation resistance minimum value per kilometer length at 20 ℃ of: rated voltage is 6KV, the section of the conductor is 16-35M < M >; the section of the conductor is 20-95 m and is not less than 750M omega; the cross section of the conductor is 120-240 m and is not less than 500M omega.
According to the oxidation data of the whole cable, the insulation performance of the crosslinked polyethylene insulated polyvinyl chloride sheathed power cable is further obtained, namely, under the conditions that the temperature is 20 ℃, the rated voltage is 6KV and the conductor section is 88 m, the insulation resistance per kilometer length is 450M omega, the oxidation degree information corresponding to the crosslinked polyethylene insulated polyvinyl chloride sheathed power cable is further obtained, the crosslinked polyethylene insulated polyvinyl chloride sheathed power cable is identified according to the corresponding preset oxidation standard, and a corresponding target oxidation model is generated as a judgment result.
For another example, the insulation resistance of the crosslinked polyethylene insulated polyvinyl chloride sheathed power cable is recorded when the insulation resistance per kilometer length is 850M ohm under the conditions that the temperature is 20 ℃, the rated voltage is 6KV and the conductor section is 88 m.
According to the cable operation monitoring method, the insulation connection equipment of which the cable is affected is obtained according to the oxidation data around the cable, whether the insulation performance of the insulation connection equipment meets the preset insulation standard is further judged, if not, the oxidized oxidation degree information of the insulation connection equipment is obtained, and a target oxidation model corresponding to the insulation performance under the current oxidation degree is generated, so that the monitoring and checking effect of the insulation connection equipment of the cable is improved.
In one implementation manner of the present embodiment, as shown in fig. 7, the environmental factors include temperature and humidity data, and step S107, that is, if the anomaly type is an external anomaly, includes the following steps of:
s701, judging whether the temperature and humidity data meet the preset environmental standard or not;
s702, if the temperature and humidity data do not accord with the preset environmental standard, acquiring a corresponding line live condition;
s703, acquiring corresponding line characteristic information according to line live conditions;
s704, judging whether the line characteristic information accords with a preset damage standard;
s705, if the line characteristic information accords with a preset damage standard, acquiring corresponding line damage data;
s706, identifying line damage data, and generating corresponding target influence factors as judging results.
In practical application, the temperature and humidity data refer to temperature and humidity data around the cable line; the preset environmental standards refer to all environmental standards which are met by the safe operation of the cable line; the line live state refers to image information of a cable line; the preset damage standard refers to a standard that the damage condition of the cable line can cause abnormal operation of the cable; line impairment data refers to impairment data of the current cabling.
It should be noted that many cross-connection ground adopts laying type, because of the influence of rainy weather, the condition of ponding in the grounding box easily appears, leads to the condition that the ground appears in cross-connection department like this easily, is equivalent to the direct ground in cable sheath both ends to lead to the sheath circulation to rise by a wide margin.
If the performance of the insulating partition board in the cable insulating joint is reduced or broken down, on one hand, the cable jackets on the left side and the right side of the cable insulating joint are communicated, a cross interconnection system is destroyed, and jacket circulation in operation is increased; on the other hand, the increased circulation causes the heat generation of the insulating partition board in the insulating joint, and meanwhile, the long-term heat generation of the insulating partition board also brings hidden trouble to the safe operation of the joint due to the poor heat dissipation environment in the joint.
On the other hand, as the operation period of the high-voltage cable increases and the outer sheath gradually ages under the influence of extreme temperature and humidity environment, the reduction of the insulation level may cause the multipoint grounding of the outer sheath of the cable, thereby changing the grounding mode of the grounding system and increasing the sheath circulation.
For example, if the current temperature and humidity data of the detected cable line does not meet the corresponding preset environmental standard, acquiring image information of the corresponding cable line, identifying a large amount of accumulated water in a cable grounding box according to the image information, further acquiring characteristic information of the accumulated water volume, judging that the characteristic information of the accumulated water volume completely meets the corresponding preset damage standard of the cable line, acquiring and identifying the grounding condition of the cable intersecting interconnection part and the condition that the cable line in the grounding box is submerged by the accumulated water, and generating corresponding accumulated water influence factors as a judgment result.
According to the cable operation monitoring method, the line live condition that the temperature and humidity data do not accord with the preset environment standard is obtained, whether the characteristic information of the line live condition accords with the corresponding preset damage standard is further judged, further, the line damage data which accord with the preset damage standard and target influence factors which cause line damage are obtained, and therefore the monitoring effect that the cable line is damaged by the outside is improved.
It should be noted that, the monitoring report includes all types of anomalies occurring in the cable running process, and further calculates a corresponding target anomaly ratio according to the induction factors in spontaneous anomalies and the environmental factors of external anomalies, where the target anomaly ratio refers to the percentages of the induction factors and the environmental factors in anomaly detection items, and determines whether each target anomaly ratio meets the corresponding alarm standard, if so, the anomaly type corresponding to the target anomaly ratio is classified into an alarm list and is alarmed, and the corresponding countermeasure strategy is matched. For example, the abnormal type of the abnormal detection item is judged to be spontaneous abnormality by the preset monitoring standard, the target abnormal proportion of the abnormal wiring item, the abnormal working performance and the abnormal node mode in the spontaneous abnormality is calculated to be 60%, 30% and 10% respectively, the target abnormal proportion of the abnormal wiring item accords with the corresponding cable wiring abnormal alarming standard, the related data of the abnormal wiring item are classified into an alarming list while being alarmed, and the corresponding wiring abnormal processing strategy is matched, so that when the same situation occurs later, the abnormal wiring item can be alarmed directly, and the abnormal wiring item is preprocessed according to the corresponding coping strategy, and the monitoring efficiency of the cable operation is improved.
