220kV电容式电压互感器故障分析

Fault Analysis on 220kV Capacitor Voltage Transformer

当前发电设备的状态检修已被许多电厂所采用,发电主辅设备的重要参数大多均已上传SIS系统,通过对SIS系统上参数的观察和分析,可以方便地实现设备状态的在线监测,从而及时发现设备的缺陷和故障。文中介绍了通过电厂SIS系统发现220kV电容式电压互感器的故障过程,并对故障原因进行了深入分析。

At presenh the （.ondilion-hased maintenance used in generating equipment has been accepted hy many power plants. Most of the important paramelets of the main and auxiliary generating equipment have heen uploaded to SIS svstem. Through the ohservation and analysis of parameters on SIS system. can easily realize equipment status online monitoring so as to detect the defects and fauhs. This paper introduced the fauh procedure in 220kV capacilor voltage transformer detected hy SIS syslem, and analyzed the fauh cause.
