摘　　要：通过模拟高压开关柜内起火,采用适量的热气溶胶灭火剂对一次设备所在的隔室实施灭火,测试热气溶胶在高压开关柜内的实际灭火能力,得出结论如下:热气溶胶发生剂的化学反应速度很快,装置启动后能够迅速产生具有灭火功能的热气溶胶灭火剂;热气溶胶能够在密闭条件良好的高压开关柜中快速散布于整个防护空间,不存在保护死区;相较于干粉灭火剂,热气溶胶灭火剂的降尘率较低,是一种非常清洁的灭火材料。Based on the simulation of high voltage switch cabinet in a fire,using the appropriate amount of hot gas sol fire extinguishing agent to the compartment where the implementation of the fire fighting equipment,test the heat sol actual fire extinguishing ability within the high voltage switch cabinet,the conclusion is as follows:hot sol agent chemical reaction speed,can quickly produce fire extinguishing function after operation,hot gas sol fire extinguishing agent;The hot gas sol can be quickly distributed in the whole protective space in the high pressure switch cabinet with good sealing condition,and there is no protective dead zone.Compared with dry powder extinguishing agent,thermal sol extinguishing agent has lower dust removal rate and is a very clean extinguishing material.
