谈电流互感器的极性及其接线

The Polarity of Current Transformer and its Connection

电力工作当中电气调试是十分关键的构成内容,尤其对于新建的电力工程而言,更是具有不可替代的重要作用。其中,电气调试在二次回路工作过程当中占据着非常重要的位置,其关乎着电力系统测量、保护及通讯等性能的正常发挥。对此,该文结合笔者多年的工作经验分析了电流互感器的极性及二次接线的原则,同时利用一些典型实例进行了具体分析。

Electrical commissioning is the key component of the electric power work,especially for the newly built electricpower project,it is an irreplaceable important role.Among them,the electrical commissioning of the two circuit in the processof work occupies a very important position,which relates to the power system measurement,protection and communicationperformance of the normal play.In this paper,combined with the author's many years of work experience,this paper analyzesthe polarity of the current transformer and the principle of the two connection.
