摘　　要：为了促进压缩空气泡沫灭火系统在变压器火灾防护的应用,进而保障换流站和变电站消防安全,对压缩空气泡沫喷淋系统射程进行试验研究。分析了喷淋射程随喷淋孔径、喷射压力、喷射角度和支管长度的变化规律,结果表明:①喷淋射程随喷淋孔径的增大而减小,随混合液流量的增大而增大;②在一定范围内,喷淋射程随喷射压力的增大而增大,到达一定的极限值时不再增大;③随着喷射角度的增加,喷淋射程先增大后减小,在喷射角度为30°时达到最大;④支管长度对喷淋射程的影响可以忽略。In order to promote the application of compressed air foam extinguishing system in transformer fire protection,and to ensure the fire safety of converter stations and substations,the spray range of the compressed air foam sprinkler system was studied through experiments.The variation rules of spray range with spray aperture,spray pressure,spray angle and branch pipe length were analyzed,the results were as follows:①The spray range decreases with the increase of the spray aperture,and increases with the of the mixed liquid flow rate.②Within a certain range,the spray range increases with the increase of the spray pressure,and stay the same when it reaches a certain limit value.③With the increase of the spray angle,the spray range first increases then it decreases,and reaches the maximum when the spray angle is 30°.④The length of the branch pipe has basically no effect on the spray range.
