介绍了变压器局部放电信号无线监测系统的系统结构、控制方法和工作流程,该系统是采用单片机进行控制的无线通信方式,它所采用的提取变压器局部放电信号的方法,是将超声波传感器传过来信号经过滤波、压扩、整流的处理,以有效地从强噪声中获取变压器局部放电信号。

Design of Wireless Monitoring System for Transformer's Partial Discharge Signals

This paper introduces the system structure,control method and work flow of wireless monitoring system for transformer's partial discharge signals,which adopts wireless communication controlled by single chip microcomputer,and the method for extracting transformer's partial discharge signals adopted by which is to obtain transformer's partial discharge signals effectively from strong noise through filtering,companding and rectifying of the signals coming from ultrasonic transducer.
