水电厂技术设备复杂、易燃易爆的危险源多,一旦发生火灾事故,扑救困难,造成的损失巨大,是重点防火灾事故单位。对已实现了“无人值班”(少人值守)的水电厂而言,由于在厂房内的人员少,给防止火灾恶性事件提出了更高的要求。防火灾事故的一个重要技术措施是设置火灾测报与联动控 Hydropower plant technical equipment is complex, flammable and explosive hazard sources, in the event of a fire accident, fighting difficulties, resulting in huge losses, is a key fire accident units.
