In the prior art, because a pantograph chassis is provided with devices for pantograph lifting driving, pantograph lowering damping and the like, the total resistance of the pantograph chassis part relative to a pantograph is relatively high, when designing a high-speed train, a pantograph installation area on a roof is usually sunk by lowering the height of a pantograph roof installation platform, and the pantograph chassis and an insulator area are subjected to drag reduction by utilizing a roof structure, but the sunk height of the roof pantograph installation area is limited due to the limitation of the height space in the passenger cabin;
because the pantograph is in a charged state in the whole working process of the pantograph body, the pantograph underframe and the roof are required to be supported through insulators with a certain height to ensure enough electric clearance, and meanwhile, the roof concave edge and the pantograph body are required to be ensured to keep electric clearance distance, so that the roof concave area is large in opening, and the air resistance effect of the pantograph underframe area cannot be completely improved through a roof concave mode.
In view of this, the present invention has been made.
