电缆火灾致因因素分析

随着用电量的增加,电缆火灾呈上升趋势。引起电缆火灾的主要原因有：导线短路、电缆过载、电缆漏电、电缆接头处接触电阻过大。在导线短路原因中分析了三相、两相和单相三种短路情况;在电缆过载原因中研究了过载引起火灾的一般规律;在电缆漏电原因中分析了漏电的常见原因;在接触电阻过大原因中,研究了接触电阻增大的恶性循环规律。

Analysing on Factor Induced from Cable Fire Disaster

With the increase of Electricity-consumption,cable fire shows a tendency towards going up.The paper firstly analyses the character of cable fire.Later,it analyzes the reason for the happening of the cable fire.The main reasons for it are the following: wire short-circulated,cable overloading,leakage fault of the cable,too big resistance of cable connector.Of the cause of wire short-circulated,three different conditions,that are three-phase,two-phase and single phase are analysed.Of the cause of cable overlo...
