电气线路故障是引起火灾的常见原因之一,以下简单介绍电气线路起火的主要原因和预防措施。电气线路起火的主要原因1.线路短路。所谓短路就是交流电路的两根导线互相触碰,电流不经过线路中的用电设备,而直接形成回路。由于电线本身的电阻比较小,若仅是通过电线这个回路,电流就会急剧增大,比正常情况下大几十倍、几百倍。这么大的电流通过很细的导线,由于电阻越大,所产生的热量就越多,会在极短的时间 Electric line failure is one of the common causes of fire. The following is a brief introduction to the main causes of fire on electric lines and preventive measures. The main reason for the electrical circuit fire 1. Short circuit. The so-called short circuit is the exchange of two conductors of the circuit touch each other, the current does not go through the line of electrical equipment, and the formation of the loop. As the resistance of the wire itself is relatively small, if only through the circuit of this wire, the current will increase sharply, than the normal case of a few times, hundreds of times. Such a large current through a very thin wire, the greater the resistance, the more heat generated, in a very short period of time
