摘要
为了研究电力电缆内因火灾早期特征,对内因火灾以及电缆火灾发生的过程进行了探究,在试验室环境下,选取合适的电力电缆进行载流温度试验,通过改变电力电缆内电流的大小,得到了相同时间坐标下,电缆电流、线芯导体温度与电缆表皮温度的对应关系,提出了通过电力电缆表皮温度对电力电缆内因火灾进行预警的方法。
In order to analyze the early characteristics of power cable internal fire,the internal causes of fire and the process of cable fire occurrence are explored.In the laboratory environment,a suitable power cable was selected for the current carrying and temperature test,by changing the size of the current in the power cable,got the relation of cable core temperature and skin temperature to current under same time coordinates,and an early warning method for internal fire of power cable based on the skin temperature of power cable was presented.
