Hybrid power type power distributed motor train unit

Abstract

The invention provides a hybrid power type power distributed motor train unit which comprises at least one power source vehicle, at least one motor car and at least one trailer, wherein a diesel generating set, a pantograph and a transformer are arranged on the power source vehicle; the pantograph is connected with a transformer; the power source vehicle and the trailer are provided with power-free bogies; the motor car is provided with a traction system and a power bogie which are electrically connected together; the power source vehicle, the motor car and the trailer are connected together through a motor train unit; the diesel generating set and the transformer are respectively connected with a motor train unit connector through switches; and the motor train unit connector is electrically connected with the traction system. The diesel generating set is arranged in the power source vehicle, and the traction system is arranged in the motor car, so that the diesel generating set and the traction system are distributed in different vehicles, and the layout that the power sources are centralized and the power is distributed is realized. Therefore, the axle weight of each vehicle is wholly alleviated, and the operating requirement on the high speed railway is met.

Description

technical field [0001] The invention relates to a railway vehicle, in particular to a hybrid power decentralized EMU. Background technique [0002] Order No. 34 of the Ministry of Railways of the People's Republic of China, which came into effect on February 1, 2013, clearly stipulates that high-speed railways are newly designed and operated 250km / h (including reserved) and above EMU trains, and the initial operating speed is not less than 200km / h. For passenger-dedicated railways, the axle load of high-speed trains is no more than 17t, and the marshalling is no more than 16 vehicles. However, the EMUs in the prior art usually adopt electric multiple units, and the electric multiple units adopt the power grid to receive electricity, and the axle load is basically below 15t. However, the EMUs of traditional DMUs include power sources, control systems, traction systems, cooling systems, etc., and the axle load of DMUs is generally above 20t, which cannot meet the axle load re...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to provide a hybrid power distributed EMU, to solve the defect that the internal combustion EMU in the prior art cannot run on the passenger high-speed railway, and to realize the reduction of the hybrid power distributed EMU. The axle load meets the requirements for running on high-speed railways
