可控硅变流系统触发脉冲参数监测及报警装置的设计

A Practicai Protection circuit supervising supply voltage

本文针对三相可控硅反并联可逆直流调速系统，介绍了一种对运行中的可控硅变流系统触发脉冲参数进行自动监测及故障报警的装置，详细说明了该装置的硬软件设计方法。

The paper introduces a effective protection circuit supervising supply voltage which enables a industry control computer to recover from the soft breakdown of supply voltage jamming, and enables it to stop work safely and to have a alarm when the supply have some trouble in hardware.
