摘要
通过电缆明火实验和阴燃实验,对电缆沟内各种火灾探测器的响应时间进行研究。研究结果表明:各火灾探测器对电缆沟火灾的敏感性由高到低依次为缆式线型感温火灾探测器、吸气式感烟火灾探测器和点型感烟火灾探测器,并利用FDS数值模拟软件对相同工况下的实验结果进行验证,其结果与实验结果基本吻合。该研究可为电缆沟火灾报警系统的选型提供参考。
The response time of various fire detectors in the cable trench are studied by the open fire and smoldering experiments.The results show that the sensitivities of each fire detector to cable trench fire from high to low are cable-type linear temperature-sensitive fire detector,inhalation smoke-sensitive fire detector and point-type smoke-sensitive fire detector in turn.The FDS numerical simulation software is used to verify the experimental results under the same working conditions.The results are basically in agreement with the experimental results.This study can provide reference for the selection of cable trench fire alarm system.
