晶闸管阀组触发系统隔离技术综述

摘要

Starting from the parallel and series use of thyristor, this article introduces some commonly used trigger isolation technique of thyristor valve assembly and points out the advantages and disadvantages of each isolation technique. The coupling energy obtainment power isolation technique of a kind of photoelectric trigger isolation technique is introduced in detail, and the application condition of this technique in high voltage motor soft start is presented.%本文从晶闸管的串并联使用谈起，介绍了常用的晶闸管阀组触发隔离技术，指出了各种隔离技术的优缺点，并详细的介绍了一种光电触发隔离技术的耦合取能电源隔离技术，并给出了此种方式在高压电机软起动中的应用情况。
