Abstract
The invention relates to a railway carriage. The essential difference between the railway carriage and a traditional railway carriage is that the railway carriage is a carriage with the functions of electrical generation, energy saving and braking. When a train needs regenerative braking, the train drives at a constant and high speed through the working of a traction engine, then the regenerative braking is carried out by using an electric generator on the multifunctional carriage and converting the electric motor into an electric generator, and electricity generated by the regenerative braking is fed back to the power grid through a pantograph on the multifunctional carriage so as to supply power for other traction engines. When the train runs on the upgrading road surface with the maximum grade, the power of the engine can be increased through the working of the electric motor, so that normal operation of the train is guaranteed. When the train runs on the level road, electric motors on the multifunctional carriage can be stopped working completely, and only the traction engine works, so that normal operation of the train can be guaranteed.
Description
Technical field
The present invention relates to a kind of railway carriage, it and traditional railway carriage have difference in essence, and it is that one has, and generating is energy-conservation, brake, and, there is significant role in the compartment of function to improving train conveying efficiency increase economic benefit.
Background technology
Train Regenerative Braking Technology, in the brake of train application very extensive, the advantage of its maximum is that the potential energy that train can be produced when the gradient road traveling changes into electric energy, then feeds back to electrical network by power transmission line.
Owing to there being the huge drop exceeding more than 5000m between the western and eastern of China, along with the development of railway construction, the mileage on railway gradient road surface can be more and more longer, this will become a huge regenerative resource, if we pass through Regenerative Braking Technology, the potential energy that train is produced on heavy grade road surface all changes into electric energy, and country will obtain a large amount of electric energy every year.
Train can produce automatic acceleration in the time of heavy grade road traveling, if (within 1 second, will automatically accelerate 0 on 20 ‰ heavy grade road surface, 69 kilometers), this has caused major hidden danger to the safety traffic of train, adopt after Regenerative Braking Technology, train just can be at full speed on long heavy down grade, safety, constant speed, operation. there is a defect in such brake modes, be exactly at sleety weather, wheel and track there will be sliding wet, if traction motor power is excessive, after changing into electrical generator, braking force will be excessive, while carrying out regenerative brake in this case, wheel can produce and slides and wriggle, when can becoming (polygonal) to cause locomotive running gear, long-term work rear wheel produces vibrations, cause gear case, the parts such as oil pressure damper damage too early.
We know that train is in the time of operation, and track has 3 kinds of forms, go up a slope, and level road, descending.The train power maximum that locomotive needs in the time of upward slope road traveling now, due to the configuration of (locomotive power) on present railway, all can be on the road of all fronts according to train, the design of can normally travelling when the gradient is maximum, such being designed to realizes locomotive energy-conservation manufactured obstacle because:
(1) the train power that locomotive needs in the time of flat pavement running is less, therefore with the locomotive power configuring now, there will be a large amount of zero load power consumptions in the time of flat pavement running, causes energy dissipation.
(2) train not only need not consume energy in the time of descending road traveling, but also will utilize brake to control the automatic acceleration that train produces, and the at this moment zero load of locomotive power consumption is larger.
(3) because train exists the problems referred to above, so Regenerative Braking Technology is also not universal at heavy grade pavement usage now, also dominate of traditional aerodynamic brake, cause the potential energy that can change in a large number electric energy, all change into heat energy having slatterned in vain by brake, because the locomotive power of configuration has caused too greatly train to exist, occurred a large amount of zero load power consumptions when level road and descending road traveling, therefore we must thoroughly address the above problem by technology innovation as early as possible simultaneously.
Summary of the invention
Use the prerequisite condition in multifunctional train compartment to comprise:
Road surface length exceedes 30 kilometers, track grade is 6 ‰ when above, hauling engine power supply grid and road surface to be reclaimed to electrical network, in the vertex on gradient road surface and the nadir on gradient road surface, disconnect with insulating material, must ensure that pantograph on train is wanted can trouble-free operation between 2 grid lines simultaneously, train is hauling engine power supply by large-sized battery pack in the time of heavy grade road traveling, ensure that train normally travels, then with the electrical generator on multifunctional railway carriage axletree with the electrical motor on compartment axletree is transformed into electrical generator carries out regenerative brake, the electricity that regenerative brake sends is by the pantograph on multifunctional railway carriage, deliver to the recovery grid line on gradient road surface, deliver to distribution substation for powering with electrical unit by power transmission line again.
