Problems solved by technology

The disadvantages are: (1) laying long-distance, large-capacity, low-voltage three-phase stator windings along the track requires a huge amount of money
(2) In order to ensure the safe floating of the train, it is necessary to spend a large amount of money to ensure the reliability of power supply
(4) Due to the heavy weight per unit length of the train, the construction of the overhead track is also a huge expense
(5) Generating a three-phase alternating magnetic field (that is, a moving magnetic field) along the track requires more and more complex control equipment
The main disadvantage of this kind of train is in the power transmission system, which is as follows: (1) Since the power transmission adopts AC power supply mode, although the power supply reliability has been improved, the power supply capacity and transmission distance are greatly limited, making the power supply along the line There are many stations, which increases investment and power loss
(2) Due to the single-phase power transmission, even if 120-degree commutation is adopted, it w

Embodiment approach

[0328] Since this new type of overhead high-speed train involves power transmission system, train system, control and communication system, overhead track system, parking station system, and other auxiliary systems, it is necessary to complete the above-mentioned six major systems and interact with each other in order to realize this high-speed train. To coordinate well. The main implementation process is as follows: (1) Establish the mathematical model of the high-speed train, and use the computer to calculate the relevant important parameters, such as air resistance, friction resistance, high-speed vibration and various conditions (such as bending, changing rails, uphill, downhill) etc.) force and so on. Determine the total power size, shape and structure of the high-speed train through these parameters, so as to design the prototype of the high-speed train. (2) Conduct a wind tunnel simulation test on a small section of the designed high-speed train to verify relevant impo...

Abstract

An over-head high-speed passenger train is characterized by that it is electrically powered in a relay mode, the IGBT frequency converting technique is used for its DC/AC conversion, and the 3-phase asynchronous motor is used as its power. Its speed is 400-500 Km/h.

Description

1. Technical field [0001] This new overhead high-speed train mainly includes the following four technical fields: [0002] 1. Power field: mainly includes power transmission and conversion technology. [0003] 2. Electronic field: mainly including train control and communication technology. [0004] 3. Mechanical field: mainly including train structure and track structure. [0005] 4. Construction field: mainly includes overhead track support frame and parking station. 2. Background technology [0006] There are mainly two types of high-speed trains currently in operation, and their working principles and performances are as follows: [0007] 1. High-speed maglev train [0008] Maglev trains use the principle of linear motors to expand the three-phase stator windings of the motor along the track in a straight line. The whole train is like the rotor of the motor, and can obtain induced current without any contact with the stator, thereby generating su...
