大型可控硅整流装置正反向保护系统的开发与应用

Development and Application of Protective System with Right and Opposite Directions for Large-Scale Silicon Controlled Rectification Unit

根据霍尔效应原理 ,采用直流大电流系列传感器 ,针对大型可控硅整流装置研制开发了一套正反向保护系统。该系统性能可靠 ,精度、稳定性高 ,使用灵活 ,价格低 ,可以满足整流器安全稳定运行的需要。

According to the principle of Hull effect,using the series of DC large current sensor,to counter large scale silicon controlled rectification unit,a set of pro tective system with right and opposite directions is developed.The performances of this system are reliable,its accuracy and stability are higher,its use is fle xible and the prise is lower,it can satisfy the requirement of safe and stable m oving of rectifier.
