Background technology:
In converting equipment actual moving process, because the reasons such as the change of the method for operation, load variations are large, hot weather make loop tie point, the plug-in strip contact ratio of the large electric current of related electric equipment be easier to produce the abnormal conditions such as heating.Equipment heating in substation operation is the potential threat of safe operation, if find not in time and process, generates heat when serious and probably causes blowing of equipment connection point, and accidents caused, this is also the difficult point in unattended substation equipment operation management.
In transformer station's daily servicing, require each substation under common load condition, monthly full station equipment is carried out to thermometric one time.During special circumstances, such as load when heavier and operation should strengthen making an inspection tour and strengthening thermometric frequency weak period, can better monitor substation equipment.To equipment thermometric, the discovering device defect of morning, strangles hidden danger and bud.Substation equipment thermometric is taked the method for infrared measurement of temperature at present, by operations staff, regularly equipment is carried out to thermometric.Quick and easy because having, highly sensitive, the untouchable telemeasurement of infrared measurement of temperature and without equipment under test is stopped transport or the advantage such as disintegration is therefore widely used in power system failure diagnostic.The equipment such as transformer, isolating switch, voltage transformer (VT) summation current transformer change because insulation ag(e)ing or loose contact cause temperature anomaly, and then accidents caused, and its complex structure, inherent vice are difficult for being found.In addition, the sense of responsibility, monitoring time interval etc. of patrolling and examining personnel in process are also comparison distinct issues, cause so a lot of defects not found in time, often wait until that defect expands while causing equipment damage to be just found.And for centralized control center, each substation number of devices is all huge, and distance between sites is far away, when special circumstances, thermometric frequency is high, greatly strengthens operations staff's workload, and work efficiency is not high, and easily careless omission, causes potential safety hazard.
Summary of the invention:
Technical matters to be solved by this invention is: provide a kind of sustainable red laser mark point for measuring temperature that sends to carry out the remote viewing system of transformer substation temperature measuring equipment detecting in real time.
The present invention is that the technical scheme that technical solution problem is taked is:
?a kind of remote viewing system of transformer substation temperature measuring equipment, comprise and treat thermometric substation equipment, remote viewing system centralized control center, remote viewing system Master Control Center and remote viewing system camera, described treating is provided with radium-shine mark point for measuring temperature around thermometric substation equipment, described remote viewing system camera top is provided with temperature measuring equipment, and described temperature measuring equipment and remote viewing system camera are all connected with remote viewing system centralized control center by data line.
Described temperature measuring equipment is infrared total image temperature measuring equipment.
After startup work of the present invention, the sustainable red laser mark point for measuring temperature that sends of temperature measuring equipment, by the observation of remote viewing system camera, can carry out real time temperature measurement to needs point, by data line, thermometric value is transferred to remote viewing system centralized control center, by supervisory system, can directly observes temperature value.The present invention is in camera shut-down operation after 1 minute in addition, can auto-breaking, stop thermometric and temperature data transmission, have advantages of energy-conservation, economize on resources.
Positive beneficial effect of the present invention is as follows:
1, the present invention can realize the function for monitoring of each equipment of transformer station.Mainly comprise main-transformer in transformer station, isolating switch, voltage transformer (VT), current transformer and high-voltage chamber switch etc., by digital infrared thermal imaging monitoring head unit, the temperature monitoring of realization to a secondary device and ruuning situation thereof, obtains the Temperature Distribution field data of transformer station under different load.
2, the present invention can realize visible ray and infrared thermal imagery fusion intelligent surveillance arbitration functions.Visible ray integration technology, makes effective dynamic monitoring to whole transformer station, can very promptly by " more existing ", to target, monitor, sees in time position and the image of current paid close attention to equipment, the accurate location of the monitoring point that forms a prompt judgement out.
3, the present invention can realize storage, management and the analysis of mass data.To day regular data scheduled store and the inventory analysis of accident, and can realize the historical temperature analysis of all temperature spots under different load; Remote distance start computer video recording and playback, any frame thermal-induced imagery of transferring in image prints and analyzes, and the complete reliable recording of moment event is got off, and makes analysis judgement in the future more convenient; Sample temperature interval and only recording exceptional or autotelic signal can be arbitrarily set, compare with legacy system, save widely record space.
4, the present invention by installing infrared total image temperature measuring equipment additional above the camera of remote viewing system, by control and the operation of remote viewing system centralized control center, can reach the real time temperature measurement to concrete substation equipment in camera visible range, increase work efficiency, reduce operations staff's the frequency of going out, can be efficiently, fast equipment is monitored.
5, the present invention can carry out conversion up and down to the camera of each substation by the control of remote viewing system centralized control center, and has zoom, focusing function, can examine for concrete equipment, reaches the object of Real Time Observation and detection.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is made further explanation and description:
Referring to Fig. 1, a kind of remote viewing system of transformer substation temperature measuring equipment, comprise and treat thermometric substation equipment 7, remote viewing system centralized control center 2, remote viewing system Master Control Center 1 and remote viewing system camera 5, treating that thermometric substation equipment 7 is provided with radium-shine mark point for measuring temperature 6 around, above remote viewing system camera 5, be provided with infrared total image temperature measuring equipment 4, infrared total image temperature measuring equipment 4 and remote viewing system camera 5 are all connected with remote viewing system centralized control center 2 by data line 3.
The present invention by installing infrared total image temperature measuring equipment additional above the camera of remote viewing system, by control and the operation of remote viewing system centralized control center, can reach the real time temperature measurement to concrete substation equipment in camera visible range, see in time position and the image of current paid close attention to equipment, the accurate location of monitoring point forms a prompt judgement out, improve the work efficiency of operation maintenance, reduce operations staff's the frequency of going out, can be efficiently, fast equipment is monitored.
