防止中性线烧毁的对策与措施

Measures for Avoiding Burn of Neutral-line

中性线烧毁是低压配电系统中经常出现的故障,但大多是对地短路.中性线烧毁悬空故障(中性线断路)在TN-C-S系统中,因不容易被及时发现而烧毁一些设备.通过对实例中性线烧毁悬空故障的分析,针对目前使用的低压配电系统,提出一些对策和措施.

Burn of neutral-line frequently occurs in all stoppage of supply system of electric current,but neutral-point hang in air rarely happens.This paper provides some measures for avoiding burn of neutral-line by analysing the causes of one example of burn of neutral-line.
