浅谈变电站独立电流互感器安装问题

A Discussion on Installation of Separate CT in Substation

变电站内的独立电流互感器和开关、母线的相对位置,有不同的安装方式。而它的一次端子的取向选择,关系到设备运行的安全水平。通过分析油绝缘电流互感器的结构特点,比较设备事故的几率,提出对应于不同一次接线方式的CT一次端子取向合理配置。

There are various installations of separate CT relative to the position of bus bars and that of the circuit breakers. The different orientation of primary terminals of CT is related to the safety level of operation. Analyzing the structure of the oil insulated CT, comparing the probabilities of their fault happenings, a rational orientation of CT primary terminals corresponding to different CT installations is proposed.
