摘要
因阻尼回路故障导致电容式电压互感器退出运行的数量越来越多,严重影响了系统的安全稳定运行。根据阻尼谐振原理及CVT已有的外部抽头,设计了一种阻尼回路测试装置,可以真实读取阻尼回路电流,配合红外测温诊断电容式电压互感器阻尼回路状态。
More and more capacitive voltage transformers are out of operation due to the fault of damping circuit,which seriously affects the safety and stable operation of the system.Based on the damping resonance principle and the existing external tap of CVT,a damping circuit testing device is designed.The current of the damping circuit can be read,and the damping circuit state of capacitive voltage transformer with infrared temperature measurement can be diagnosed.
