摘要：

为更好地解决电气柜火灾发展速度快、灭火难度大等问题，基于热敏绝缘材料构建了1 种集精准探测与可靠灭火于一体、安装简易、可重复使用的电气柜区块式自灭火装置。通过对电气柜火灾热点区域的分析，确定热敏绝缘材料布置方案，并进行了相关灭火试验。结果表明，该自灭火装置在多种工况下都能较快扑灭电气柜火灾。线缆火试验中装置在20~35 s 内实现灭火；较大规模火灾试验中在29~37 s 内实现灭火；多位置起火试验中在18~75 s 内实现灭火。重复性灭火试验表明该装置具有良好的重复使用能力。

Abstract: In order to better solve the problems such as the rapid development of electric cabinet fire and the difficulty of fire extinguishing, this paper constructed an electric cabinet block type self-extinguishing device based on thermal insulation material, which integrates accurate detection and reliable fire extinguishing, is easy to install and can be used repeatedly. Through the analysis of the hot spot area of the electric cabinet fire, the arrangement scheme of heat- sensitive insulating material was determined, and relevant fire extinguishing tests were carried out. The results show that the self-extinguishing device can extinguish electric cabinet fire quickly under various working conditions. In the cable fire test, the device realized fire extinguishing within 20~35 s. In the large-scale fire test, the fire suppression is realized within 29~37 s. In the multi- position fire test, fire suppression can be realized within 18~75 s. The repeated fire - extinguishing test shows that the device has good repeatability.
