Research on Leakage Current Detection Method of Zinc Oxide Arrester Based on Fourier Analysis
摘要
Abstract
The detection of leakage current of zinc oxide lightning arrester is of great significance for maintaining the stable oper-ation of the entire power system.Based on the Fourier transform method for voltage and current detection signal,this paper re-alizes the harmonic analysis of the leakage current of zinc oxide lightning arrester.The overall architecture,working principle,and design scheme of a real-time detection system for leakage current of zinc oxide lighting arrester are discussed from both hardware and software aspects.For the design purpose of real-time detection and strong anti-interference ability,a capacitive compensation method is adopted to measure the leakage current,and a software program is designed using the TMS320LF2407 chip as the core.The experimental results show that the designed detection system can effectively detect the leakage current of the zinc oxide lightning arrester and obtain the resistive current component and harmonic component,with the third harmonic component being only 60.7 μA.It provides a good technical support for evaluating the operation status of zinc oxide lightning arrester.关键词
