摘要

某些高压SF

断路器在一定条件下可能出现喷管外击穿现象

即断路器断口的击穿路径发生在喷管的外表面。本文介绍了这一现象的试验研究结果。它表明这一现象的出现和喷管表面的电荷积累有关

并受电路条件和喷管的几何形状的影响。

Abstract

In some SF6 circuit breakers there was a probability of breakdown occurred not within the nozzle

but rather along the nozzle external surface.This paper presents some experimental results on this external breakdown phenomenon.It was demonstrated that the external breakdown may be induced by the charge accumulated on the nozzle surface and was affected by the nozzle geometry and the circuit condition.
