摘要
介绍了电缆隧道及综合管廊电力舱火灾性状、特点,分析了目前电缆隧道火灾探测应用技术与其存在的问题。针对电缆接头区(部位)火灾自动探测报警技术的现状,提出了一种能够非接触探测被保护物体温度的缆式线型感温火灾探测器,对电缆接头区域进行连续在线探测,并结合产品技术特点和实体火灾试验数据,给出非接触缆式线型感温火灾探测器工程应用方法。
The fire characteristics of cable tunnel and integrated pipe gallery power cabin were introduced,and the cable tunnel fire detection and its problems were analyzed.Against the status of cable joint zone fire detection and alarm,a kind of cable type linear temperature sensitive fire detector which can detect the temperature of protected object non-contacted was put forward to detect the cable joint zone online and continuously.The engineering application of non-contact cable type linear temperature sensitive fire detector was suggested combing with the product technology feature and fire test data.
