配网箱式设备声波矩阵局部放电测试仪的研制与应用

Development and Application of Acoustic Matrix Partial Discharge Tester with Cage Equipment

基于高压设备局部放电的特性,研究并设计了配网箱式设备声波矩阵局部放电测试仪,该仪器采用定向超声波传感器组成的4×4阵列,多点位接收被测方的超声波信号。多点位阵列可以将多个传感器接收到的信号进行对比,将局部放电位置直接显示在阵列图形上,确定局部放电位置。

In this paper,on the basis of the characteristics of high pressure equipment for partial discharge,research and design the match box type equipment acoustic matrix partial discharge tester,the instrument adopts the directional ultrasonic sensors of 4 x4 array,multiple point receiving of ultrasonic signal being measured point can be multiple sensor array,comparing the received signal will be partial discharge location displayed directly on the array pattern,determine the location of partial discharge.
