電氣動力總成損壞

電氣動力車輛 ，即其動力總成 由電池 、 集電弓 、發電機、變壓器和牽引馬達 等組成。

Damage to such a powertrain subsystem can occur from collisions , but it is much more severe when caused by overloading electrical systems with excessive current , premature reverser operation, and traction motor overspeeding . Exposure to fire , or submersion in water, can also damage this subsystem.

電氣動力總成在電流過高時，可能發生災難性損壞，導致車輛動力完全失效並起火。

Small amounts of electrical powertrain damage are also accumulated from normal operation of power sources and traction motors, which falls under regular wear and tear. The higher the current passing through traction motors, the more damage is inflicted. While this damage cannot be avoided, by operating the machines efficiently it can be reduced to a minimum.

受損的電氣動力總成可以被修復 。
