煤矿井下6/10kV漏电保护研究
Study of 6/10kV leakage protection in coal mine
本文研究了煤矿井下6/10kV漏电保护，通过对漏电故障时零序特征分量的分析，提出了分类漏电保护的方法，该方法消除了漏电保护中过渡电阻的影响，同时对于不同的接地方式具有更强的适应性。保护的准确性得到了提高，较好的了解决了现有漏电保护的误动和拒动。
In this paper we disscuss the 6/10kV leakage protection in the coal mine.Analyzing the zero sequence component features during the leakage fault,we proposed leakage protection classification method which eliminates the influence of the transition resistance during the protection. but for different grounding has better adaptability. The accuracy has been enhanced , and it is better to solve malfunction and refuse of the current leakage protection.
