利用张紧的熔丝来进行火灾探测的技术始于第二次世界大战期间,目前一项全新的电子系统已经被开发出来。新型眼镜蛇系统(COBRA TM system)可以使用点型探测器(见图1),或者使用一个线型感温探测器(见图2)布置在排烟机的表面。点型探测器是定温型的(252℃),即可以按照70 cm的间距单排布置在排烟机的表面,也可以布置在独立设备上。线型感温探测器也是定温型的(185℃),导线的绝缘体在预定
The use of tensioned fuses for fire detection began during World War II and a completely new electronic system has now been developed. The COBRA TM system can be equipped with a spot detector (see Figure 1) or with a linear temperature detector (see Figure 2) on the surface of the smoke exhauster. Point-type detectors are fixed-temperature type (252 ℃), which can be arranged in a single row at a distance of 70 cm on the surface of the smoke machine can also be arranged in a separate device. Linear temperature detector is also a constant temperature type (185 ℃), the insulator wire is scheduled
