摘要
目前电网发生多起高压变电站二分之三接线方式电流互感器回路维护不当导致的事故,因二分之三接线电流互感器二次回路的潜伏性风险特殊性,维护方法与其他电压等级电流互感器存在一定的差异。本文在通过案例的基础上分析总结出高压变电站二分之三接线方式电流回路潜伏性风险,并电流互感器维护控制措施,并将之运用于工程实践。
At present accidents caused by improper maintenance in 3 /2 wiring of substation side current transformer circuit happened a lot. Because of the particularity of secondary loop in 3 /2 wiring current transformer,there is a certain difference maintenance method with other current transformer voltage level. In this paper,on the basis of those cases,analyzed and summed up the potential risk in3 /2 wiring current loop of high voltage transformer substation and the maintenance and preventive measures of current transformer,and will be applied to engineering practice.
