CMOS集成块在水电站控制电路中的应用

Application of CMOS Integrated Circuit Blocks to the Control Circuits of Hydropower Stations

在水电站控制电路中,为完成全站逻辑选控开停机,逻辑选控同期合油开关、跳油开关的功能,用CMOS集成电路替代分立元件,从而提高了水电站的自动化程度,缩小了集控台体积,也有利于安装、调试和维修。

In the control circuit design of hydropower stations, the CMOS integrated circuit blocks were used instead of seperated components, in order to realize logic choice and control of starting and stoping units for whole station, logic choice and control oil circuit breakers with synchro-on, and cut-off oil circuit breakers. Thus, the automaticity of hy- dropower stations were raised, the volumes of integrated control desks were decreased, their installations, debuggings and maintenances are convenient.
