摘要

真空断路器以其优越的灭弧性能和免维护的优点大量运用于变电站的10 kV电压等级中

它主要起分合线路的负载电流和切断故障电流的作用。由于真空断路器熄灭容性电流比感性电流要困难得多

因此

电容器组开关因未能灭弧而引发的爆炸事故时有发生。文章通过分析一起10 kV电容器组开关的爆炸事故

分析其中的原因

并提出相关预控措施。

Abstract

Vacuum circuit breaker with its superior arc interruption and maintenance-free performance

is widely used in 10 kV substation for switching load current and cutting off fault current of line.As the capacitive current is more difficult to be interrupted than the inductive one by the vacuum circuit breaker

therefore

such fault as explosion due to the arc not interrupted by the capacitor’s switch sometimes happened.In this paper

through analyzing an explosion accident of 10 kV capacitor bank switch

the related pre-control measures have been proposed.
