220kV地下变电站消防技术优化研究

Optimization Research on Fire Prevention Technologies and Strategies for 220kV Underground Substation

以上海220 kV济南站为例,对220 kV全地下变电站火灾危险性进行分析,结合规范确定消防灭火系统的技术原则和策略,介绍了室内外消火栓、预作用自动喷水灭火、主变水喷雾灭火、烟烙尽全淹没气体灭火、移动式灭火、火灾探测报警和消防排水等系统;以及济南站消防系统设计的方法、经验,并对消防系统的优化提出建议。

Taking the 220 kV Jinan underground substation as example,this article points out the fire hazard of underground substation and analyses the technical principles and strategies of its fire fighting system by combining relevant norms.The substation fire-fighting system includes the internal and external fire hydrants system,pre-action sprinkler system,water spray fire extinguishing system for main transformer,the gas fire extinguishing system,portable fire extinguishing system,the automatic fire alarm system and the drainage system for fire-fighting.After introducing the designing methods and practical experience of the fire-fighting system for Jinan underground substation,this article puts forward the suggestions on the optimization of fire-fighting system.
