·我段2037机车运行中突然出现主电流几乎没有,磁场削弱电阻严重发红的故障。由于当时对故障原因吃得准,果断地关掉第一组牵引电动机的故障闸刀,使机车维持运行回段。上述现象的产生是由于1位电机的C_2大线与6位电机的C_1大线在靠1位电机C_2端跨线联结的鼻子松动、氧化,造成接触电阻增大,因而发热直至着火、烧断(见图1)。第一组
· Section 2037 locomotive suddenly appeared in the operation of the main current is almost no magnetic field weaken the resistance of a serious redness of the fault. At that time, due to the reasons for failure to eat quasi-decisively turn off the first set of traction motor fault knife, the locomotive to maintain the operation back. The above phenomenon is caused by the C_2 line of the 1-bit motor and the C_1 line of the 6-bit motor being loosened and oxidized by the crossover wire of the 1-bit motor C_2, causing the contact resistance to increase, thus generating heat until ignited and blown (see picture 1).
