摘要
本文介绍了一套可同时测量电力设备局部放电电、声信号的微型计算机测量系统。系统使用SUPER-PC/XT微型计算机及DMA高速A/D卡来完成对信号的数据采集和处理。通过对一路电脉冲和三路超声波脉冲的联合测量,使系统具有测量局部放电、识别干扰、对局部放电源初步定位的功能。试验室及生产现场的实测结果表明,测量系统是成功的。
A computer-aided measuring system for simultaneously measuring electric and acoustic signals in power equipments during partial discharge is described in this paper.SUPER-PC/XT microcomputer and high speed DMA-A/D card are used for data acquisition and processing.By combined measuring 1 channel of electric pulse and 3 channels of acoustic pulses this system has the capabilities of measuring partial discharge, identifying interferences and rougly locating the partial discharge source.The test results obtained in laboratories and power substations have shown that the developed partial discharge measuring system is successful.
