Technical background of the present invention
High-voltage electrical equipment utilizes infrared imagery technique principle as one of important means measuring power system transformer substation equipment safety operation, provides the non-destructive monitoring of the equipment infrared imaging picture in power transmission and transformation field.Online High-Voltage Electrical Appliances are made up of scene infreared imaging device and infrared image delivery network two major part.Infrared imagery technique obtains effective application in recent years in electric system, Utilities Electric Co. in all parts of the country utilizes portable infrared thermoviewer to operating High-Voltage Electrical Appliances: high-voltage switch gear (isolating switch), current transformer, voltage transformer (VT), transformer, the equipment such as high-tension line carry out temperature survey, find potential faults, greatly reduce the various faults of electrical equipment, the operation troubles of high-voltage electrical equipment is done alarm function faster, utilize its portable equipment can measure arbitrary position of equipment, the various data analysis measured, determine the reason of fault, associate power company has also formulated relevant technical manual, improve the validity measured.Its performance and convenience are the topics that people are concerned about always, and have very large relation to the measurement performance of Portable infrared imaging instrument and measurement point, the people of measurement, the direction of measurement and temperature, weather etc.In order to improve the safe operation of electrical network, State Power Corporation's Portable infrared imaging instrument is measured and is proposed to explicitly call for and strict regulation, and the People's Republic of China's power industry standard (DLT907-2004 heat power equipment infrared detection directive/guide) formulated and (DLT 664-1999 charging equipment infrared diagnosis technology application directive/guide).Before nineteen ninety, electric system does not all have too large attention to it to the requirement of power equipment, the less test doing this respect, adopts the method having fault just to repair, to the reliability of grid equipment be all correlated with require of today high.Mainly contain the reason of three aspects: 1 its technical merit is low in the past, do not have infrared imagery technique and infrared measurement of temperature correlation technique, this respect does not have testing tool and requirement.The utilization of 2 computing machines is also popularized, and the attention of power industry to infrared imagery technique is inadequate.3 power industry management are ineffective, and the departments such as production, power transformation do not set up infrared imaging expert engineer to manage, and technology and management are not all paid attention to.
The requirement to infrared imagery technique of current use mainly adopts portable infrared imaging device to carry out on-line testing to High-Voltage Electrical Appliances, this proving installation mainly work about electric power person utilizes portable infrared thermoviewer to measure to scene, and this method of testing exists following problem:
1, measuring accuracy is poor, and extensive work needs manual intervention; Different test person often has different test results;
2, relevant device is more, needs manpower transport to arrive substation field and uses, can not accomplish to fix a point, fix time, determine direction, take the altitude;
3, the data of test cannot be carried out in real time, do not have comparability;
4, a lot of transformer station all have employed unmanned now, and difficulty of test strengthens.
Beneficial outcomes of the present invention
1, measuring accuracy is high, and function is complete, and without the need to too many manual intervention, just can automatically complete.
2, utilize network technology not need substation field, and a people just can once complete.
3, the real time data of all measurements can preserve and measure in real time.
4, the quantity of information measured is not only a complete infrared imaging figure, also comprises the correlationship figure etc. of temperature and electric current.
