摘要
随着变配电系统中6k V^35k V中低压开关柜的广泛应用,由开关柜内因弧光短路故障而引发供配电设备损坏事故日益增多。本文根据在新疆油田电网中因弧光短路引发的停电事故,结合相关理论分析了弧光短路故障的成因及特征,介绍了在实际工程使用电弧光保护装置来减少因弧光短路故障引发停电事故的技术措施。
With in 6kV - 35kV LV/MV switchgear were widely used in distribution system, caused by the switchgear internal short-circnit fault are power supply equipment damage accidents. In this paper, according to the power outage caused by the are short circuit in the power grid of Xin Jiang oilfield, combined with the theo~ to analyze the causes and characteristics of arc short circuit fault and introduces the technological measure of the electric arc protection device is used in the actual engineering to reduce the arc short circuit cause power failure.
