摘要
配电网中小电流接地系统中最常见的故障是单相接地,占到80%以上,而且很多短路故障也是由单相接地故障引起的.为提高配电网安全运行水平,达到快速区分故障线和非故障线的目的,文章设计了一种站外型分布式选线装置,具体介绍了该装置的主要构成,提出了该装置实现选线的流程,总结了各部分的主要功能及技术方案的实现,以期有助于人们更好地了解该站外型分布式选线装置,进而更好地推广应用该装置.
The most common fault in the medium and small current grounding system of distribution network is single-phase grounding,accounting for more than 80%,and many short-circuit faults are also caused by single-phase grounding fault.In order to improve the safe operation level of the distribution network and achieve the purpose of quickly distinguishing the fault line and non fault line,this paper designs a distributed line selection device outside the station,introduces the main structure of the device in detail,puts forward the process of the device for realizing the line selection,summarizes the main functions of each part and the realization of the technical scheme,so as to help people better understand the external type of the station Cloth type line selection device,and then better promote the application of the device.
