摘要
本文以电网运行中常见的一起10k V系统接地故障查找方法为例,通过分析得出了10k V金属性接地故障的原因,大致可分为以下三类:110k V单一线路接地故障;2两条及以上线路同名相接地;310k V母线设备故障。在此基础上,作者以自己亲身工作经历,讲述了快速排查接地方法、步骤。并提出了相关的改进建议和措施,以确保故障处理快速、正确。
This paper takes locating method of the ground connection fault of a common lOkV system in the operation ot the power grid as the example. Through the analysis, it gets the causes of the gold property ground faults of lOkV system. The faults can be roughly divided into the following three categories: ①thc single line grounding faults of lOkV system;②the same phase ground connection of two or more lines; ③the faults of bus bar equipment of lOkV system. Based on these, the author takes the work experience to expound the immoral rapid screening grounding methods and steps and put forward the related improvement suggestions and measures to ensure quickly and correctly hand the faults.
