摘要
本文介绍了目前企业6~10kV电网常用的电流保护的星形接线方式,详细分析了电流互感器V形接线时,在不同的故障形式下,保护装置的动作组合,指出V形电流保护接线方式是6~10kV企业电网的首选,但对安装相应有严格的要求,必须是两个同名相。
This paper introduces the present enterprise 6-10kV power grid commonly used current protection of star connection mode, a detailed analysis of the current transformer V connection, in different failure forms, the protection of the combination of action, and points out that the V current protection mode of connection is 6- 10kV power grid enterprise first choice, but to install the corresponding have strict requirements, must be two same phase.
