摘要
电力系统运行经验表明,单相接地故障绝大多数都是瞬间性的,特别是架空线路。本文说明了偏磁式消弧线圈的工作原理及技术参数,并结合风电场的实际情况,对安装偏磁式消弧线圈前后运行状况进行对比分析,表明偏磁式消弧线圈可以进一步提高供电的可靠性。
Power system operation experience shows that single-phase grounding fault in the vast majority are transient, especially the overhead line. This paper illustrated the working principle and technical parameters of the arc-suppression coil with magnetic bias, combined with actual circumstance of a wind farm, made the contrast analysis on the running status of installation of arc-suppression coil with magnetic bias before and after, which shows that the arc-suppression coil with magnetic bias can further improve the reliability of power supply.
