摘要
文章介绍了电容式电压互感器的结构原理,分析了运行中的220kV电容式电压互感器电磁单元故障引起的过热现象,提出以红外检测技术为基础,结合停电诊断性试验的方法来进行联合故障诊断,诊断结果准确可靠,并对电容式电压互感器的现场检测和故障诊断提出了建议。
The structure principles of capacitive voltage transformer （ CVT ） are introcluced and the overheating phenomena caused by internal fault of electromagnetic unit are analyzed in the paper. Based on infrared detection technology, a method combined with the power failure diagnostic test is proposed to diagnose the fault accurately and reliably. Finally some proposals on field detection and faults diagnosis of CVT are presented.
