电力电缆隧道消防技术方案分析

Analysis of Fire Protection Technology in Power Cable Tunnel

随着上海城市建设的快速发展和电力需求的增加,上海部分输电网已经向地下空间发展;随着电力电缆隧道数量的不断增加,正在结合变电站进线通道和市政道路的改造,逐步建设电力隧道网络。通过分析上海地区电力电缆隧道消防技术的应用方案,叙述了电力电缆及其附件的选型、温度在线监测及其消防报警系统的应用,介绍了在电缆隧道中使用防火包带、防火封堵、防火隔断以及干粉灭火器的设置等防火措施。论证了上海电网的电力电缆隧道消防技术方案是经济、合理、可行的,能够确保电力电缆在隧道中安全运行。

With the rapid development of Shanghai City, the scale of power tunnel continues to expand. This paper analyses the main scheme of fire protection technology in Shanghai power cable tunnel, including how to choose power cables and their accessories, temperature monitoring and fire alarm system, fireproof plugging, fire partition, dry powder fire extinguisher settings and so on. This paper draw a conclusion that Shanghai power grid has a set of economic, reasonable, feasible power cable tunnel fire protection technical scheme, to ensure the safe operation of cable tunnel.
