本文所谈火烧电线短路,是指电气线路在通电状态下,由于火焰和火灾中的热作用,使电线绝缘层受到破坏失去绝缘性能导致的短路。尽管它属于火灾发生的结果而不是构成起火的原因,但若能了解它的形成过程,派生的火灾危险性,短路熔痕的宏观特征,将对否定火灾是由电线短路引起,查找起火部位,分析起火原因有很大帮助。火灾进程中的产物在绝大多数建筑物中,都布设有电气线路。发生火灾后,当火焰和炽热的气流接触电线时,要不了多久 In this paper, the burning of short-circuit wire, is the electrical circuit in the power state, due to the thermal effects of fire and flames, so that the wire insulation is damaged due to loss of insulation short-circuit. Although it belongs to the result of a fire and not to the cause of fire, if one can understand its formation process, the risk of fire and the macroscopic characteristics of short-circuiting marks will be caused by a short-circuit in the negative fire, Analysis of the causes of fire is very helpful. Products in the process of fire Electrical circuits are laid out in most buildings. When a fire breaks out, it does not take long for the flame and the hot air to come in contact with the wire
