Multi-Channel Three-Dimensional Positioning of Partial Discharge in Switchgear Based on Ultrasonic Wave

某些类型的局部放电发生时,伴随超声波信号的产生,文章对开关柜内超声波的传播规律进行论述,建立多通道三维立体定位模型和算法,并通过对局放所产生的超声波信号计时点算法的研究,实现自动搜索计时点并进行较精确的三维定位的目标。

Some types of partial discharge occur,accompanied by the generation of ultrasonic signal.Expounding the propagation law of ultrasonic wave in the switchgear,this paper establishes multi-channel three-dimensional positioning model and algorithm by studying the algorithm of ultrasonic wave signal timing point from the partial discharge,the automatic search and accurate three-dimensional positioning of timing points is achieved.
