核电站中核级继电器控制电路的设计探讨

Nuclear power plant nuclear level relay control circuit design

根据巴基斯坦卡拉奇核电站仪控总体方案的半数字化技术特点,本文对继电器机柜的仪控分级进行探讨,建立一套仪控信号分级的方法,对核级继电器电路的电气隔离设计进行剖析,以安全注入系统低压安注泵的逻辑控制设计应用为例,提出了核级继电器控制电路的设计方法,取得了良好的效果。

According to semi-digitalization technical requirement of I＆C overall design in Pakistan Karachi Nuclear Power Plant,the article discusses and puts forward I＆C classification of the relay cabinet. It analyses the electric isolation design of nuclear relay circuit, and in logic control design of low pressure injection pump for example, putting forward the design way of nuclear relay control circuit, which gets good effect.
