Title
(EN) Integrated monitoring system and method for overvoltage and partial discharge of transformer based on bushing tap
(ZH) 基于套管末屏的变压器过电压和局放综合监测系统及方法
Abstract
(EN) The invention relates to an integrated monitoring system and method for overvoltage and partial discharge of a transformer based on a bushing tap. The system includes a monitored object of the transformer bushing, an integrated sensor module for overvoltage and partial discharge, a coaxial cable transmission module, an attenuation and low pass filter module, a band pass filtering and amplifying device module, a data acquisition device module, a data analysis, display, storage and transmission module, and a data monitoring and diagnosis module. Compared with the prior art, the integrated monitoring system and method for overvoltage and partial discharge of the transformer based on the bushing tap has the advantages of being simple, practical, reliable, reducing electromagnetic interference,and fully utilizing the multi-monitoring of the bushing tap.
