一种应用于换流站水处理装置的控制接口电路

摘要

本文提出了一种水处理控制系统的接口电路。该电路采用两付接点实现三台水泵的启停控制及水泵间定时轮换运行的控制电路，解决了特高压换流站水处理装置与用户水泵控制的特殊接口问题。%The control interface circuit uses two pairs of contacts control three sets of pump starting and stopping and pump rotation timing operation,and applied for water treatment device in UHVDC converter station,solved the water treatment device in UHVDC converter station and the user water pump control special interface problem.
