变电站室内智能通风联动控制研究与应用

Research and Application of Indoor Intelligent Ventilation Linkage Control in Substations

针对变电站室内存在温度过高、湿度过高、SF6泄漏、易发生火灾、氧气不足等风险,提出变电站室内智能通风联动控制的一种解决方案。对变电站室内环境实现实时监测与控制,根据室内各种环境参数的实时值控制轴流风机的启停、运行数目、转速、转向、运行时间等,满足运维对环境的需求。通过某110 kV变电站主变室进行实例验证,结果表明该方案具有可行性和推广价值。

Aiming at the risk of high temperature,high humidity,SF6 leakage,easy fire,and insufficient oxygen in the substation room,a solution for intelligent ventilation linkage control in the substation room is proposed.Realtime monitoring and control of the indoor environment of the substation is realized,and the start-stop,running number,speed,steering and running time,etc.of the axial flow fans are controlled according to the real-time values of various indoor environmental parameters,so as to meet the needs of operation and maintenance for the environment.The main transformation room of a 110 kV substation is verified by an example,and the results show that the scheme has feasibility and promotion value.
