Description
Technical field
This utility model relates to a kind of detecting device, particularly relates to a kind of scene ultrasonic partial discharge instrument device for fast detecting.
Background technology
High-tension electricity equipment is one of most important equipment in electric power network, once break down, will result in large-area power-cuts, and economic development and social stability are caused significant impact. Shelf depreciation is sign and the form of expression of the apparatus insulated destruction of high-tension electricity, if shelf depreciation long-term existence, meeting acceleration equipment is aging, even can cause in any case and puncture or flashover, cause the destruction of insulation. Therefore, the shelf depreciation of detection high-tension electricity equipment promptly and accurately, it is possible to effectively grasp apparatus insulated situation, it is ensured that electric power safety steady production.
When there is shelf depreciation in power equipment, the phenomenons such as electric pulse, ultrasound wave, electromagnetic wave, gas analyte and hot-spot can be produced, according to These characteristics, currently mainly there are the multiple detection methods such as electric pulse detection method, ultrasonic Detection Method, superfrequency detection method, gas chromatography, it is possible to the internal shelf depreciation of detection power equipment. Ultrasonic Detection Method due to few by electrical Interference, highly sensitive, good reliability, be capable of fault location and the advantage such as on-line monitoring, live detection, obtain in power system at present and be increasingly widely applied.
When there is shelf depreciation in power equipment, intermolecular meeting hard hit in region of discharge, due to electric discharge heating, moment, stereomutation occurred medium simultaneously, and these factors macroscopically can produce pulsed pressure wave. Ultrasound wave Partial Discharge Detection method is through sonac, detects the pulsed pressure wave medium frequency acoustic component more than 20kHz.
Owing to ultrasound wave follows the propagation law of mechanical wave when power equipment internal communication, in different medium, spread speed is different, and reflection and refraction can occur when different medium is propagated. The ultrasonic signal detected is analyzed, it is possible to judge the type of shelf depreciation, intensity and discharge position, it is achieved that the detection of power equipment shelf depreciation.
But, along with scientific and technological progress and social development, ultrasonic sensor and ultrasonic partial discharge instrument are various informative, of a great variety, also result in the very different of detection performance simultaneously, and the parameter such as the mid frequency of such as sensor, frequency bandwidth, sensitivity and the linearity would be likely to occur difference.For State-Oriented Maintenance in Power Grid, using the result of not ultrasonic partial discharge instrument detection after testing, its accuracy is difficult to judge, and then the state of high-tension electricity equipment is difficult to accurate judgement, directly influences the safe and stable operation of power equipment safety and electrical network.
