提高大功率晶闸管整流器触发系统可靠性的措施——在线热备触发系统

Some Measures Adopted for Improving the Reliability of the High Power Thyristor Rectifier Trigger System——on Line Changeover Trigger System

大功率晶闸管整流器在工业生产中已普遍使用,特别在氯碱和电解铝行业中大有发展趋势。然而,有些负荷特别是电解铝行业对整流器的安全可靠性要求很高。这就对大功率晶闸管整流器触发系统安全可靠性提出一个严峻的问题。文章重点讨论如何提高大功率晶闸管整流器触发系统安全可靠性的问题。

High power thyristor rectifiers have found widespread application in industry,partcularly in chlorinealkalis and electrolytic aluminium industry However,some loads, particularly in electrolytic aluminium industry,puts in a strict requirement for the safety and reliability of the rectifier.This poses a question concerning the safety and reliability of the high power thyristor rectifier trigger system.This paper puts emphasis on improving its safety and reliability.
