摘要
中小型水电站的渗漏排水大多采用继电器控制方式,接线复杂,维护工作量大,可靠性低,采用微型可编程控制器LOGO！进行控制改造后,简化了接线,减少了维护工作量,提高了运行可靠性。
Relay control mode is largely used in moderate or midget hydro-electric plant, but its wiring is complex, its maintenance workload is more, and its reliability is lower. When the subminiature Programmable Logic Controller LOGO! has been used in leakage draining, the wiring and the maintenance workload is reduced, and the reliability of run is improved.
