摘要
380 V与660 V配电系统在选煤厂中应用较为普遍。本文主要论述了中性点直接接地系统与中性点经高电阻接地系统,分析了380 V接地系统和660 V接地系统工作状态,阐述了660V系统接地电阻器阻值选取与漏电保护整定计算的方法。该方法实用性较好。
The power distribution system of 660 V and 380 V are more popular in coal preparation plant.This paper mainly discusses the neutral point direct grounding system and neutral point through the high resistance grounding system, that is, 380 V grounding system and 660 V grounding system, and the neutral grounded system of 660 V(the neutral grounded system with the high resistance), which expounds practical method of resistance selection to grounded resistor, and the setting method about the system leakage protector. This method has good feasibility.
