摘要
油浸式电容器室是变电站的重点防火部位,根据南方电网变电站设计标准,户内变电站油浸式电容器室需设置七氟丙烷气体灭火系统。笔者以某110 kV户内变电站为例,详述了组合分配式内储压七氟丙烷气体灭火系统的设计计算过程,分析影响七氟丙烷灭火效果的设计参数并对其进行设计优化,总结了组合分配式七氟丙烷气体灭火系统设计过程中的注意事项。
The oil-immersed capacitor room is the key fireproof part of substation.According to the substation design standard of China Southern Power Grid,heptafluoropropane gas fire extinguishing system should be installed in oil-immersed capacitor room of indoor substation.Taking a 110kV indoor substation as an example,the design and calculation process of the combined distribution internal pressure storage heptafluoropropane gas fire extinguishing system is described in detail,the design parameters affecting the fire extinguishing effect of heptafluoropropane are analyzed and optimized,the matters needing attention in the design process of the combined distribution heptafluoropropane gas fire extinguishing system are summarized.
