The invention provides an integrated system of a low-flow-resistance low-noise pantograph and a flow guide structure of a high-speed train. The system comprises a train roof, a pantograph, a pantograph train roof mounting platform and a flow guide structure, the pantograph is mounted on the pantograph train roof mounting platform on the train roof, and holes are formed in an upper arm rod and a lower arm rod of the pantograph respectively. The bow head is of a wing-shaped structure, the flow guide structure comprises a vehicle roof front flow guide cover and a vehicle roof side flow guide cover, radiation noise outside a vehicle is remarkably reduced, and noise pollution to the environment is reduced. The running resistance of the train is reduced, and the operation cost is lowered. By researching and optimizing the pantograph of the high-speed train, the surrounding flow field structure of the pantograph, the noise generation mechanism, the development law of the pantograph and the resistance and noise reduction, the method has important theoretical and practical significance in the aspects of reducing the overall noise of the high-speed train, reducing noise pollution to the surrounding environment, reducing energy consumption and improving the comfort of passengers.
