摘要
地下变电站由于空间封闭,火灾危险性很高。同时,由于地下变电站位于核心城区,周边负荷密集且重要程度高,火灾易造成重大经济损失和严重负面舆情。本文首先综合分析了适用于地下变电站的气体灭火系统,对七氟丙烷、IG541进行了全面剖析,对于不同应用场景给出了明确的选型结论。然后,结合消防新技术发展分析了适合地下变电站变压器、开关柜、电缆等重点部位的消防提升措施,提出了针对性的消防提升方案,为全面提升地下变电站的消防能力提供了有力参考。
Due to the confined space,underground substations have a high risk of fire.Moreover,as they are located in the core urban areas with dense and important surrounding loads,fires can cause significant economic losses and serious negative public opinions.This paper first comprehensively analyzes the gas fire suppression systems applicable to underground substations,conducts a thorough examination of heptafluoropropane and IG541,and provides clear selection conclusions for different application scenarios.Then,in combination with the development of new fire protection technologies,it analyzes the fire protection improvement measures suitable for key areas of underground substations such as transformers,switchgear,cables,etc.And proposes targeted fire protection improvement plans,providing a strong reference for comprehensively enhancing the fire protection capabilities of underground stations.
