电缆出线井防火技术探讨
|
摘要
针对电缆出线井中的电缆越来越密集,当电缆出线井发生火灾难以使用手提式灭火器扑灭的问题,研制了一套适用于电缆出线井的干粉灭火系统。该系统主要包含监测系统和干粉灭火系统。对电缆出线井进行了现场火灾模拟,发现该系统可在100s内扑灭较大的火灾,且反应迅速、可靠。
The cable in the cable outlet well is more and more dense.To the problem of difficult to use portable fire extinguishers to extinguish when the cable outlet well fire occurs,a dry powder automatic fire extinguishing system suitable for cable outlet well was developed in this paper.The system mainly consists of two parts:monitoring system and dry powder fire extinguishing system.Field fire simulation of cable outlet well was carried out to verify the performance and reliability of the system.It was found that the system could extinguish large fires within 80 sand the system was designed to be responsive and reliable.
