ZD114牵引电机泄漏电流超标原因及防止措施

ZD114牵引电机多次出现泄漏电流超标,经分析主要原因是从齿轮箱窜入电机内部的油污侵蚀了定子线圈和电枢,导致泄流超标。针对该情况,对电机进行了加装排油管的改造,将窜入的油排至电机外,解决了泄流超标的问题。

Preventive Measures of Excessive Leakage Current Traction Motor ZD114 Causes

ZD114 traction motor excessive leakage current phenomenon appears more than once, after analysis, mainly fleeing motor oil from the gearbox internal erosion of the stator coil and armature, resulting in excessive leakage current. For this case, the installation of the motor exhaust pipe renovation, the fleeing motor oil motor exhaust to the outside, to solve the problem of excessive discharge.
