摘要：
In this paper, the full-scale cable fire test is carried out in the fire compartment of cable trench in standard substation in order to explore the influence of fire detector sensitivity. The point-type temperature detector, point-type smoke detector, cable-type temperature detector, and suction-type smoke detector are used to test the fire alarm sequence. The temperature field, combustible gas concentration, and fire alarm sequence of fire detector with different sensitivity are simulated by FDS. The results show that: The numerical simulation results are in good agreement with the experimental results. The lower the alarm threshold, the shorter the response time of fire detector. The sensitivity of suction-type smoke detector has great influences on the detection results.
