摘要
针对常用的水、ＣＯ＿２、卤代烷三种灭火系统，分别介绍了灭火介质的性能，对三老的优缺点进行了比较、分析。经过对三种灭火系统的综合评判，认为ＣＯ＿２灭火系统最佳，水次之，卤代烷较差。文章还介绍了三种灭火介质主要参数的计算方法，叙述了国内外大中型水轮发电机中灭火系统的应用情况。
The properties of three kinds of fire-extingushing media for hydrogenerator, water, CO 2 and halon, are described .And then, Analysis, Comparision and comprehensive evalustion for these medis are made, evaluating results showed that CO2 occupied first place, water carne second, and halon was bit inferior. At last, parameter calculation and application to hydrogenerators of three ftre- extinguishing media are presented.
