农村低压配网漏电保护器泄漏电流触电识别Rural Power Network Leakage Protector Leakage Current Electric Shock Recognition

摘要:

由于用户操作不规范以及用户设备老化引起台区总漏电保护装置经常性误动并难以恢复投运,为了保证供电可靠性,不得不降低总漏保投运率,但难以兼顾用电安全性。本文从实际出发分析总结农网漏保投运的实际情况及原因,通过对泄漏电流的组成及形成原因分析,提出了将触电识别的方法应用于漏电保护器,改善漏电保护器在农网低压配变运行中的误动率,在提高农网供电可靠性的同时提高用电安全性。

The general leakage protection device in zone area unwanted trips frequently and recovery operation difficultly due to users’ improper operation and equipment aging; for this reason, in order to guarantee reliability of power utilization, general leakage protection device has to turn off operation, which is difficult to consider safety of power utilization. Started with the reality, this paper summarizes the actual situation and causes of rural power grid leakage protector operation, analyzes composition and forming reasons of leakage current, proposes to apply the method of electric shock identification to leakage protector to improve the error rate of leakage protector in low voltage transformers area of rural power grid and improve safety of power utilization while enhancing reliability of power utilization.
