Description
Technical Field
The application relates to the technical field of transformer oil tests, in particular to a device, a method, equipment and a storage medium for injecting test carrier gas.
Background
The method for judging the internal fault of the transformer by using the chromatographic analysis method of the dissolved gas in the transformer oil is widely applied to a power system. The principle of the method is that test carrier gas is added into quantitative transformer oil, then heating oscillation is carried out, and after dissolution balance is achieved, mixed gas is taken out for chromatographic analysis test.
At present, a method for injecting test carrier gas in a transformer oil chromatographic analysis test is that a tester selects a 5mL syringe to extract the carrier gas and manually and slowly injects the carrier gas into a 100mL syringe containing transformer oil. In the process of injecting the test carrier gas, a tester is required to hold a 100mL injector by one hand to keep an included angle of 30-40 degrees with the horizontal plane, and hold a 5mL injector by one hand to slowly inject the test carrier gas, and the gas injection speed is controlled to be just continuous when the gas bubbles discharged from the oil by the needle point are kept. However, the method mainly has the following problems: 1) when the 5mL injector injects test carrier gas into the 100mL injector, the needle head is easy to deviate to cause damage of the injector or fracture and bending of the needle head; 2) the tester needs to take the test carrier gas from the pressure reducing valve of the compressed gas cylinder, if the output pressure of the pressure reducing valve is improperly adjusted, the compressed gas can rush out the glass inner core of the 5mL syringe for taking the test carrier gas, and the tester is easily damaged and cut by the glass; 3) the uncertainty of the volume of the balance gas affects the accuracy and the working efficiency of the test. Ideally, after a tester manually injects a fixed 5mL test carrier gas into a transformer oil sample to be tested and heats and oscillates, 3 to 4.5mL balance gas is expected to be obtained, but the volume difference of the balance gas is large due to different contents of dissolved gas in different transformer oils.

Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, an apparatus for injecting a test carrier gas according to an embodiment of the present application includes:
the system comprises a sample rotator, a sample information recognizer 101, an automatic sample injector 104, a historical test database 102 and a control system 104;
the sample rotator is provided with a plurality of clamping positions with adjustable angles, the clamping positions are used for fixing a 100ml injector filled with a transformer oil sample and controlling the 100ml injector to rotate stably after responding to an injection instruction of a user;
it should be noted that the sample rotator of this embodiment adopts a rotating disk, and 12 adjustable-angle positions are provided, and the positions are used for fixing the 100mL syringes containing the transformer oil samples, so that the sample rotator of this embodiment can store 12 100mL syringes, and the nipples of the 12 syringes (in order to ensure the sealing performance, the nipples of the 100mL syringes containing the transformer oil are sealed by rubber caps) are fixed positions on the rotating disk, and every two positions are spaced by 30 degrees, the 100mL syringes can be adjusted to 35 degrees from the horizontal plane, as shown in fig. 2, where B in fig. 2 is the 100mL syringe, and C is an automatic sample injector.
And controlling the 100ml injector to smoothly rotate after receiving the injection instruction of the user.
The sample information identifier 101 is used for identifying the 100ml injector when the 100ml injector rotates to a preset position, acquiring transformer information corresponding to the transformer oil sample and transmitting the transformer information to the control system;
it should be noted that, the present two-dimensional code scanning identification technology is adopted for identification of the transformer oil sample of this embodiment, and the sample information identifier mainly adopts a fixed two-dimensional code scanner. The key information of the transformer oil sample mainly comprises a transformer station name, an equipment name and a phase difference, and the key information is made into a two-dimensional code by a tester before the transformer oil sample is taken and is pasted on a 100mL glass syringe for sampling. During testing, a tester places a 100mL glass syringe on a clamping position (station) of a sample rotator, the sample rotator clamping position (station) rotates the sample to a sample information identifier for sample identification before injecting carrier gas into each sample, and then transformer information is output to a control system.
Further, when the sample information identifier 101 identifies that a certain transformer is a transformer requiring injection of a test carrier gas, the control system generates a rotation suspension control instruction to the sample rotator to control the 100mL injector to suspend rotation, that is, during identification, the 100mL injector stops rotating, and it is determined whether to control the 100mL injector to suspend rotation or to control the next 100mL injector to rotate to a preset position until the sample information identifier identifies the transformer oil sample information.
A historical test database 102, which is used for storing the relation information of the historical test carrier gas injection amount and the corresponding historical balance gas volume of various types of transformers;
it should be noted that the dissolved gas content of the transformer oil and the injected amount of the test carrier gas will determine the volume of this balance gas. The transformer has good sealing performance, and the probability of the content of the dissolved gas in the oil mutating is lower when the transformer normally runs, so that the database of the gas chromatography test data test carrier gas injection amount and the balance gas volume is established, and the latest test data is adopted. Table 1 below shows the recorded volume of the balance gas after the oil samples are heated and oscillated, and since the existing method is to add fixed 5mL of test carrier gas (nitrogen), the injection amount of the test carrier gas in the newly-built database is 5.0 mL. The 500kV equipment has good sealing performance, the gassing property of the transformer oil is better than that of equipment with a voltage class of 220kV or below, so the content of dissolved gas in the oil is less, and the volume of balance gas is correspondingly smaller. The following table also shows that 500kV equipment has less than 3.0mL of transformer oil degassing, and the secondary oscillation is required by adding carrier gas continuously during the test. The sealing performance of 110kV equipment and the gas evolution performance of transformer oil are poor, the content of dissolved gas in the transformer oil is high, and the volume of balance gas of the transformer oil is over 5.0 mL.
TABLE 1
The control system 103 is used for analyzing the transformer information and the relation information according to a preset test carrier gas injection amount calculation strategy to obtain a test carrier gas injection amount, generating a control instruction according to the test carrier gas injection amount and a preset injection speed and sending the control instruction to the automatic sample injector;
the control system is a brain that controls the sample rotator, the sample information identifier, the automatic sample injector, the test carrier gas, and the gas line. In the process of putting in and taking out an oil sample of the transformer, the rotation of the sample rotator needs to be controlled, the two-dimensional code scanning of sample information needs to be controlled in the sample identification relay, and the inclination and the rotation of the sample need to be controlled to be matched with the work of the automatic sample injector. The opening and closing of the electromagnetic valve are controlled during the cleaning and gas taking of the automatic sample injector, and the needle head of the automatic sample injector is controlled to accurately prick into the rubber cap of the injector nipple in the automatic sample approaching process, so that the injector nipple is not damaged or deformed and broken due to deviation.
The following is a description of the experimental carrier gas injection quantity calculation strategy preset in this example:
from transformer oil chromatographic theory, the test result is only related to the volume of the balance gas and is not related to the injected test gas carrying quantity, but the volume of the balance gas influences the accuracy of the test and the normal operation of the next step. Therefore, it is theoretically possible to flexibly inject a proper amount of test carrier gas based on the content of dissolved gas in the transformer oil to control the balance gas to 3.0 to 4.5 mL. After the transformer oil is injected with test carrier gas and heated and oscillated, the dissolution balance is formed between oil gas, and the content of the gas dissolved in the oil reaches a saturation value, so that the gas can not be further dissolved, and then the balance gas is formed. After the oil gas is dissolved and balanced, the transformer oil is supersaturated, so that the variable of the injected carrier gas is equal to the variable of the balance gas. Meanwhile, the minimum scale of the 5mL glass syringe for transferring the balance gas and reading is 0.2mL, and the volume of the balance gas required in the oil chromatography test is accurate to 0.1mL, so that an estimation reading mode is often adopted, and the small number of the volume reading of the balance gas can be reduced if the small number is an even number, so that the accuracy of the test is improved. The volume of the balance gas in the previous test is between 3.0mL and 4.5mL but the decimal number is odd, or the volume of the balance gas in the current test is in the critical position of 3.0 and 4.5, which may be beyond the range due to small dynamic changes of the content of the dissolved gas in the transformer oil, and the volume of the balance gas in the previous test is not between 3.0mL and 4.5mL due to too low or too high content of the dissolved gas in the transformer oil, which all have the requirement of balance gas volume adjustment. Taken together, we set the target value for the equilibrium gas volume for this experiment to 3.8mL with an even decimal number at the median value of 3.0mL to 4.5 mL. When the injection amount of the test carrier gas is determined based on the content of the dissolved gas in the transformer oil, the sample information of the transformer oil is obtained, the established test carrier gas injection amount and balance gas volume database is inquired, the test carrier gas to be injected in the test is determined according to the previous test condition, and the strategy is as follows:
and the automatic sampler 104 is used for acquiring the test carrier gas and injecting the test carrier gas into the 100ml injector after responding to the control instruction, and the moving track of the injector needle of the automatic sampler is parallel to the 100ml injector.
It should be noted that the auto-sampler of the present embodiment specifically includes: the gas pipeline, the electromagnetic valve, the syringe needle and the quantitative tube; the electromagnetic valve is used for responding the injection quantity of the test carrier gas in the control instruction to open and close the valve, so that the test carrier gas enters the gas pipeline and is input into the quantitative pipe for storage; and the injector needle is used for injecting the test carrier gas into the 100ml injector according to the preset injection speed (which can be set according to the actual situation by a person skilled in the art and is not limited herein) in the control instruction when the electromagnetic valve is closed.
The device for injecting test carrier gas provided by the embodiment of the application accurately controls the needle head to be pricked into the rubber cap to enter the nipple of the 100mL glass syringe to inject test carrier gas by utilizing the full automation and high precision advantages of the automation equipment, and completely breaks away from the skill level, experience and dependence of testers. The automatic equipment controls the quantitative tube to replace a common 5mL glass syringe to take test carrier gas and inject gas through a puncture needle, so that the operation risk of possible cutting and puncture in the manual operation of testers is eliminated. The dissolved gas content in the transformer oil is calculated according to the historical balance gas volume in the relation information, a proper amount of test carrier gas is injected based on the dissolved gas content in the transformer oil to replace the current fixed injection of 5mL of test carrier gas, the volume of the balance gas formed after one-time heating oscillation can be controlled to be 3-4.5 mL, the volume of the balance gas can be transferred to a 5mL glass injector to carry out accurate reading without exceeding the capacity, the cleaning (1mL gas consumption) of a sample injection injector and the chromatographic analysis repeatability test (2mL gas consumption) can be met, the accuracy of gas chromatographic analysis is ensured, the situations that testers continue to add the test carrier gas for secondary oscillation and re-oil extraction test are avoided, and the working efficiency of the test is improved. Therefore, the technical problems of high potential safety hazard, poor accuracy and low efficiency in the prior art are solved.
