摘要
针对电容式电压互感器故障真实案例,通过红外测温、故障录波、油化试验和解体检修等方法,对电容式电压互感器电磁单元过热故障的原因进行了深入分析,找到了导致电容式电压互感器电磁单元过热的根本原因,并基于此次故障分析,给出了在实际运行和检修中关于电容式电压互感器的建议。
Based on the real case of capacitive voltage transformer fault, the cause of overheatingfault in the electromagnetic unit of capacitive voltage transformer is analyzed thoroughly throughmeans of infrared temperature measurement, fault recorder, oil test and disassembly overhaul inthis paper. According to the analysis ,the root cause of this overheating fault is found out, and onthe base of this fault analysis, some suggestions about the capacitive voltage transformer during op.eration and maintenance are put forward.
