【摘要】：為了分析懸掛鏈?zhǔn)捷椪帐业幕馂?zāi)危險(xiǎn)性,采用實(shí)驗(yàn)測(cè)定得出室內(nèi)典型輻照物品的點(diǎn)著溫度,通過(guò)設(shè)置3組火災(zāi)場(chǎng)景模擬得到卡源故障下各火災(zāi)場(chǎng)景輻照室內(nèi)溫度變化曲線。結(jié)果表明:各火災(zāi)場(chǎng)景卡源初期1 h,溫度上升速度較快。隨著時(shí)間的增長(zhǎng),室內(nèi)溫度不斷上升,但上升速率逐漸放緩。在火災(zāi)場(chǎng)景A,B,C等3組條件下卡源故障分別發(fā)生9,4,2.4 d后,室內(nèi)局部溫度能達(dá)到210℃,室內(nèi)輻照物品有可能被引燃。
[Abstract]:In order to analyze the fire risk of hanging chain irradiator, the ignition temperature of typical irradiated items in the room was measured by experiments, and the indoor temperature variation curves of each fire scene under kaysource fault were obtained by setting up three groups of fire scenes to simulate the fire scene. The results show that the temperature rises rapidly at the beginning of 1 hour in each fire scene. With the increase of time, indoor temperature continues to rise, but the rate of rise gradually slows down. In the fire scene A, B, C and other three groups of conditions, the card source failure occurred 9, 4, 2.4 days later, the indoor local temperature can reach 210 鈩，
