机车火灾损失巨大,修复时间长。因此,研究机车火灾的起因,认真总结防火的经验是十分必要的。作者根据多起SS_1型机车的起火故障分析,总结了该型机车起火的十种原因,提出了有关的预防措施意见,供读者参改。一、牵引电机电缆起火 SS1型机车牵引电机采用185°D CH—3000型电缆,工作电压较高,可达1500V,工作电流较大,可达700A,具有不延燃、耐磨等优良性能。一般情况下,不会起火。但是,在电缆的接线部位,如果接线鼻子压
Huge locomotive fire damage, long repair time. Therefore, it is very necessary to study the cause of locomotive fire and conscientiously sum up fire prevention experience. Based on the analysis of many fire accidents of SS1 locomotives, the author summarizes the ten causes of the locomotive fires and puts forward the opinions on the preventive measures for the readers to modify. First, the traction motor cable fire SS1 locomotive traction motor using 185 ° D CH-3000 cable, high voltage, up to 1500V, larger operating current, up to 700A, with no delay, wear and other excellent performance. Under normal circumstances, it will not catch fire. However, if the wiring nose part is pressed in the wiring part of the cable
