Abstract:

6 kV power supply system adopts indirect neutral point grounding way. Traditional line selection ways have some shortcomings, such as poor reliability and low success rate. The article researches the operation characteristics of power supply, and presents a fault line selection scheme of neutral point controllable short-circuit concept.

摘要：

露天矿6 kV供电系统采用不直接中性点接地方式，传统的选线方式存在一些缺点，可靠性差、成功率较低。研究露天矿供配电系统运行特点，提出了一种中性点可控短路概念的故障选线方案。
