摘要
为提升特高压换流站消防系统灭火效能,针对目前以水喷雾灭火系统为主的消防设施应对换流变火灾蔓延等恶劣情况存在的不足,提出一种将消防炮增设于阀厅挑檐上的固定式压缩空气泡沫消防系统(compressed air foam fire-fighting system,CAFS)。该系统在不占用现有设备空间和检修通道的情况下,利用其灭火能力强、响应速度快、灭火效率高等特点,成倍提升变电站内换流变集中区域的消防能力,保证了最不利情况下换流变火灾消防工作需求。
In order to improve the efficiency of the fire fighting system of UHV converter station,based on the shortcomings of the existing firefighting facilities,such as water spray firefighting system,to deal with the bad situations such as the fire propagation of converter transformer,a fixed compressed air foam fire fighting system(CAFS)is proposed,which adds the fire gun on the eaves of the valve hall.Without occupying the existing equipment space and maintenance channel,the system makes use of its characteris-tics of strong fire extinguishing ability,fast response speed and high fire extinguishing efficiency to multiply improve the firefighting ability of the convergent area in the station and to cope with the convergent firefighting work requirements in the most unfavorable sit-uation.
