Analysis of Circuit Breaker Failures Due to Lightning Strokes
摘要
笔者通过对高压断路器雷击损坏故障的分析
指出输电线路雷击故障开关跳闸、在开关自动重合或强送合闸之前
线路上再次遭受雷击是造成高压断路器雷击损坏故障的主要原因
提出应采取安装出线避雷器等防范措施。
Abstract
This paper studies the circuit breaker failures due to lightning strokes
and finds that successive lightning stroke on tbe breaker tripped due to the former lightning stroke is the main factor resulting in these failures.It suggests that a lightning impulse attester should be installed at the line side of a line circuit breaker.
