固定式喷灌系统经济管径的计算方法

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).

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。
