摘要
电容式电压互感器(CVT)是变电站的重要设备之一,其运行状况直接影响系统运行安全可靠性.本文结合一起110k V电容式电压互感器(CVT)的故障案例,通过应用油色谱技术进行故障初步判断,并结合电气试验、解体检查等方法验证了油色谱的故障诊断结果,反映油色谱技术,能有效的掌握电压互感器的运行状况,及时、准确地进行故障诊断.
Capacitive voltage transformer（CVT） is one of the important equipment of substation,The operating conditions directly affect the system＇s safety and reliability. This paper combinations a fault cases which based on a 110 k V capacitor voltage transformer（CVT）, Through the application of oil chromatography technology to determine the initial fault first, and then combined with electrical tests, disassembly and other methods to verify the oil chromatography technology,s fault diagnosis which reflects the oil chromatography technology, can effectively grasp the operation of the voltage transformer timely and accurate failure diagnosis.
