十多年来,笔者在协助省内外七、八座小水电站改造励磁系统及处理故障的过程中,对于提高可控硅静止励磁系统可靠性方面积累了点滴的经验.这些经验,虽无新的内容,但对工作在生产第一线的同志来说,或许有些帮助.不周之处,请批评指正.可控硅静止励磁系统的故障,除元件损坏外,多数是由于环节欠完善、调整失当或接触不良等所引起.而后面几个因素又容易造成元件损坏,因此本文就这方面谈谈我们的意见. For more than a decade, the author has accumulated a bit of experience in improving the reliability of the SCR static excitation system in assisting the seven or eight small and medium hydropower stations in the process of rebuilding the excitation system and handling faults. Although these new experiences Content, but for work in the production line comrades, perhaps some help. Insufficient, please criticism correction. SCR static excitation system failure, in addition to component damage, mostly due to incomplete links, adjust Misconduct or poor contact caused by the following several factors are likely to cause damage to the components, so this article to talk about our views in this regard.
