向家坝水电站机电消防设计及优化

Fire-fighting System Design and Optimization of Electrical and Mechanical Equipments in Xiangjiaba Hydropower Station

从消火栓、水喷雾的供水水源、供水压力和供水流量等几个方面对向家坝水电站机电设备的消防设计进行了分析。针对阀门操作引起压力波动过大导致管网漏水问题,提出了在消防供水总进口处的减压阀后安装泄压持压阀的优化建议。

The fire-fighting system of electrical and mechanical equipments in Xiangjiaba Hydropower Station is analyzed from several aspects of water sourees, water pressure and water flow of hydrants and water sprays. The actual operation tests find that the opens and closes of some valves can lead to pressure rise of pipeline because of water hammer and the pressure rise causes water leakage of pipeline. The optimization of installing pressure relief / holding pressure valve following the pressure reducing valve in the main inlet of water supply pipeline is proposed.
