摘要
本文针对10kV电力系统中继电保护的现状进行了分析。对10kV系统中应配置的继电保护及过电流保护装置进行了说明。提出了采用零序电流保护来进行单相接地保护。
This paper analyses the state of the art of relay protection in 10kV electric power system, and explains the relevant relay protection devices and over-current protection devices which should be applied to the 10kV electric power system. And afterwards, method of use of zero sequence current protection to fulfill single phase earthing protection is suggested.
