摘　　要：公伯峡水电站主变压器根据SDJ278-90《水利水电工程设计防火规范》的要求及GB50219-95《水喷雾灭火系统设计规范》的有关规定采用固定式水喷雾灭火系统,系统由火灾报警装置、自动控制装置、高位水源、水雾喷头及管网等组成,在灭火时通过水雾喷头将带有一定压力的水雾化,从而起到吸热、切断氧气、稀释燃烧液等功能,灭火能力大大提高,可以达到"以防为主,防消结合"的目的。The stationary water spray fire-extinguishing system is adopted for the main transformer of Gongboxia Hydropower Station in compliance with the requirements of “Fire Protection Code for Design of Water Resources and Hydropower Engineering”(SDJ278-90) and “Design Code of Water Spray Fire-extinguishing System”(GB50219-95). The Fire-extinguishing system is composed of fire alarm device, automatic control device, high-level water source, water spray nozzle and pipe network. When putting out a fire, the water is sprayed through nozzles with certain pressure so as to absorb heating, cut off oxygen, dilute combustion liquid etc,. The capability of extinguishing the fire is greatly increased in order to reach the purpose of fire protection as a main manner in combination with fire control and extinction.
