CRH3G型高速动车组牵引电机冷却通风道安装浅析

Installation analysis of CRH3G High-speed EMU traction motor cooling air duct

将CRH3G型高速动车组牵引电机冷却通风道的安装方式与CRH3型高速动车组进行了简单对比,并详细介绍了CRH3G型高速动车组牵引电机冷却通风道的安装要点。冷却风道采用吊装方式安装,避免了焊接对空气动力学牵引端受力的影响,保障了列车的安全运行。

In this paper,the CRH3G high-speed EMU is simply compared with CRH3 high-speed EMU about the installation way of cooling air duct of traction motor, and main installation points about CRH3G is expounded. By hoisting the cooling air duct are fully introduced and it avoids the effects of welding on the load of aerodynamics traction components, and guarantees the safe operation of trains.
