電気動力伝達システムの損傷

電気的動力伝達システムとは、バッテリー、パンタグラフ、主電動機など、車両を動かす電気システムを指します。電気的動力伝達システムの損傷は衝突によって発生する可能性もありますが、そのほとんどは過剰な電流による電気システムの過負荷によるものです。操作を誤ったり、電流計や速度計の数値を見過ごしたりすると、車両が動けなくなったり、火災が発生したりする可能性があります。

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 .
