摘要
随着电网不断发展,电缆使用增多,电网单相对地电容和接地电流随之增大。通过比较配电网中性点的几种接地方式,分析了中性点经消弧线圈接地方式可以限制接地短路电流的工作原理,提出选择消弧线圈的基本要求,介绍了消弧线圈自动调谐装置在部分电网的运行效果。
With the development of electric network and the electric cable used widely, single-phase capacity and earth current of the network are increasing. Comparing the several grounding ways of the distribution network neutral point, the article puts forward the operation principle ,which arranged in network central place can restricts earth short-current, provides the basic standards in selecting the arc suppressing wire coil, introduces the operation effects of the arc suppressing wire coil automatic resonance device in part of electric network.
