变电站干式电抗器故障监测方法研究

干式电抗器是电力系统的主设备之一,解决干式电抗器的故障检测方法问题十分必要。通过对干式电抗器工况分析和监测方法的比较,基于温感监测方法建立了现场实施的方案,并且在安顺换流站一台交流滤波器的干式电抗器上安装了监测系统,取得了监测的技术数据,解决了干式电抗器故障前无法监测的技术难题,对干式电抗器的安全稳定运行意义重大。

Research of Fault Detection Method of DryType Power Reactor at Substations

Drytype power reactor is one of the main equipments of the power system, and it is necessary to provide method for its fault detection. Comparing several detection methods and analyzing operation situation of the reactor, this paper sets up an practical scheme based on the method of temperature induction, implements it on one drytype reactor of AC filter at Anshun Converter Station and gains certain detective data of the reactor. Therefore, the proposed scheme can solve the problem of no way to detect drytype power reactor before its fault happened, and this is meaningful for safty and stable operation of the reactor.
