消弧线圈成套装置不同型式的比较

Comparison Different Types for Arc Blow Compensator Package

中性点不接地系统中发生单相接地时,单相接地电容电流如果过大,弧光不能有效熄灭,会产生过电压,造成事故进一步扩大,消弧线圈是该问题的重要设备。

When single-phase grounding is happened in unearthing system of neutral point, if the capacity current of single- phase grounding is too high that arc can not extinguish effectively and excess voltage would be created that make the accident further expanded, so arc blow compensator is the primary eauipment for this kind of problem.
