摘要
在分析现有井下各种漏电保护原理存在不足的基础上,以目前自然直流选择性漏电保护研究为基础,以中性点不接地的两分支电网为例分析了单相漏电情况下自然直流选择性漏电保护原理,并介绍了以计算机为核心的直流选择性漏电保护的简单实施方案。
On the basis of analyzing disadvantages of principles for all kinds of selective leakage protection being used currently, this paper analyzes a selective leakage protection system of natural directive current according to two branches distribution networks of un-grounding system,and designs a system realized by PC according to this theory.
