摘要
针对双电动机拖动一台辅机设备几次出现烧毁电机的情况 ,根据现场实际 ,在原保护的基础上加装一个由两个电流互感器形成差流的电流继电器 ,构成横差保护 ,可以有效地解决此问题。
Based on the facts that motors of auxiliary facilities dragged by two motors were destroyed, a differential current relay formulated by two current transformers is added on the original protection.This problem can be effectively solved by this span difference protection.
