可控硅励磁装置在发电厂中是一种常见的励磁设备,对于它的维护保养好坏,直接影响到机组的安全运行,由于有的设备未设置整流波形的监视装置和控制部份运行状况的监视装置,因此给这些设备的巡回检查、运行维护保养工作带来很多的不方便。笔者根据对我站4台可控硅励磁装置的维护、保养所积累的经验,谈谈如何加强对可控硅励磁装置的维护保养工作。可控硅励磁装置是由控制和整流两大部份组成,即通常所说的弱电和强电两部份。在运行过程中,我们要经常对其运行状况进行检查、巡视、记录和分析。但是,在运行过程中,有的故障和缺陷不易
Silicon controlled rectifier excitation device in power plants is a common excitation equipment, for its maintenance is good or bad, a direct impact on the safe operation of the unit, because some equipment is not equipped with rectified waveform monitoring device and control part of the operating conditions Of the monitoring device, so to these equipment tour inspection, operation and maintenance work to bring a lot of inconvenience. The author based on my station 4 SCR excitation device maintenance, maintenance of accumulated experience, talk about how to strengthen the SCR excitation device maintenance work. Silicon controlled rectifier excitation is controlled and rectified two major components, which is commonly referred to as weak and strong two parts. During operation, we regularly inspect, inspect, document and analyze its health. However, during operation, some faults and defects are not easy
