摘要
阐述基于西门子S7-200系列PLC,设计一套220KV油浸式电力变压器恒温控制系统,以PLC控制变频器驱动冷却供水泵,实现温度闭环控制,满足油浸式电力变压器恒温控制及安全稳定运行的要求。
Based on Siemens S7-200 series PLC, a set of 220 kV oil immersed power transformer constant temperature control system is designed. PLC controls frequency converter to drive cooling water supply pump to realize temperature closed-loop control, so as to meet the requirements of oil immersed power transformer constant temperature control and safe and stable operation.
