500kV输电线路绝缘子测污方式对比分析

Comparison Analysis of Methods for Contamination Meas urement on Insulator of 500 kV Transmission Line

通过对湖北500kV交流输电线路运行过程中零挂和在线方式进行绝缘子等值盐密测量数据对比分析,得出在2种方式下测量数据对比参照依据,并探讨了应用在线监测方式测量泄漏电流作为定量参数进行污秽等级划分和进行状态化清扫的优越性。

Through the comparison of measu rin g results of ESDD using off-line and on-line measuring method on 500kV transmi ssion line in service, the reference basis was built between the data gained usi ng these two methods. The advantages of using on-line measuring method to monit or leakage current as a quantitative parameter to classify the grade of contamin ation and condition based cleaning were discussed.
