变电站电缆层汛情监测及智能排水系统的研制

Development of Flood Monitoring and Intelligent Drainage System for Substation Cable Layer

变电站的电缆层大多位于底层,地势较低,梅雨季节或台风天气时,电缆层容易产生积水,若无法及时将积水排出,会导致电缆线路的绝缘下降,引发线路短路故障,影响电网的稳定运行,运维人员进入电缆层进行排水设施巡视也存在危险。针对无人值守变电站,设计出一款汛情监测及智能排水系统,可以监视电缆层水泵工作状态和水位信息并把故障信息实时远程上传,根据水位情况智能排水,提高运维效率,保证人员安全,提高电网的稳定性。

The cable layer of the substation is mostly located at the bottom layer,with a relatively low terrain.During rainy seasons,the cable layer is prone to water accumulation.If the water accumulation cannot be discharged in a timely manner,it can lead to a decrease in the insulation of the cable line,cause short circuit faults,and affect the stable operation of the power grid.It is also dangerous for operation and maintenance personnel to enter the cable layer to inspect drainage facilities.For unmanned substations,the team proposes a flood monitoring and intelligent drainage system that can monitor the working status and water level information of the cable layer water pump,and remotely upload fault information in real-time.Based on the water level,the system can intelligently drain water,improve operation and maintenance efficiency,ensure personnel safety,and improve the stability of the power grid.
