摘要
气体灭火系统越来越多地使用在广电机房及附属变配电室,大量使用气体灭火系统必将是一种趋势。以七氟丙烷、超细干粉灭火系统这两种气体灭火系统为例,阐述了气体灭火系统的结构特点、工作原理,以及防护区灭火剂用量的计算方法。
Gas fire extinguishing system is more and more widely used in radio and television room and its auxiliary electricity transformer and distribution room.It will be a trend to use gas fire extinguishing system in large quantities.Taking heptafluoropropane,superfine dry powder fire extinguishing system as example,this paper expounds the structural characteristics and working principle of the gas fire extinguishing system and the calculation of the amount of extinguishant used in the protection zone.
