摘要
Abstract
Aiming at the problem of inductive over-voltage occurred on 500 kV Yaxi-Fuquan Transmission Line Ⅱ during DC de-icing,this paper does theoretical calculation and actual tests,resulting in a conclusion that this inductive over-voltage is caused by the disruptive discharge of the over-voltage protection gap on the DC de-icing line due to the inductive voltage perturbation of parallel-operating transmission lines,and it can be overcome in a way to change the de-icing method,or to adjust the gap distance settings of the rectifier device.关键词
