電気的動力伝達システムの損傷

車両 の電気的動力伝達システム は、バッテリー やパンタグラフ 、発電機、コンバーター、主電動機 などの電気品で構成されています。

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.

High electrical powertrain damage can be catastrophic, potentially fully immobilizing the vehicle and setting it on fire.

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.

Damaged electrical powertrains can be serviced .
