七氟丙烷灭火系统在变电站的应用研究

摘要

研究七氟丙烷气体灭火系统的构成、功能,以及防护区压力保护、火灾探测,分析实际应用中存在的问题,并提出改进措施.这些措施应用到变电站的气体灭火系统中,可防止防护区围护结构损坏,及早地探明火灾,提高气体灭火系统的可靠性.%Structure and function of HFC-227ea gas fire extinguishing system are introduced,the pressure protection and fire detection of protection zones are studied.Problems existing in the actual application are analyzed,and measures for improvement are put forward.These measures applied to substation gas fire extinguishing system can prevent the damage to enclosure of the protected area,and can improve the reliability of gas fire extinguishing system.
