摘要
电压互感器是用来监视系统电压的重要电力设备,主要有电磁式电压互感器和电容式电压互感器,目前电容式应用得最为广泛,特别是在110kV及其以上系统。文章简单介绍了电容式电压互感器的结构原理,对某110kV母线电容式电压互感器二次电压异常进行了研究分析,查找出了异常原因,并针对性地提出了一些防范措施,为其他电力设备事故分析研究提供了一定的参考价值。
Voltage transformer is an important power equipment used to monitor system voltage .Voltage transformer is mainly divided into electromagnetic and capacitor voltage transformer. Capacitor is most widely used at present, especially in the llOkV power system and above. Simply introduce the structure and principle of capacitor voltage transformer. Analyze and study on the abnormal secondary voltage of a I lOkV capacitive voltage transformer, and find out the reason of the anomaly. Then put forward some corresponding measures which can provide some reference value for analyzing the accident of other power equipment.
