动态电阻测量法用于评估SF6断路器灭弧室状况的探讨
摘要
介绍了一种不用打开灭弧室就可以评估断路器灭弧室状况的方法———动态电阻测量法
用此法很容易判断弧触头的烧损数值 .根据弧触头的烧损数值
就可以决定断路器是否需要大修
Abstract
To assess the condition of arc quenching chamber of circuit breaker without disassembly itself
Dynamic Resistance Measurement (DRM) is introduced in this paper. The burn out length of arc contactor can be easily measured by DRM. By using this burn out length of arc contactor
it can be determined if circuit breaker needs to be overhaul or not.
