specific Embodiment approach

[0023] Fig. 1~5 shows, a kind of specific embodiment of the present invention: a kind of lamination power bus bar that is used for the levitation chopper of maglev train, insulating top plate 11, conductive positive plate 12, insulating partition plate 13, conductive The negative electrode plate 14 and the insulating bottom plate 15 are stacked and bonded in sequence to form the motherboard 1 .

[0024] Figures 1, 2, and 4 show that the motherboard 1 of this example is provided with a power terminal connection hole group 2 adapted to the power terminal of the power module, including the positive polarity hole 21 of the power terminal, the negative polarity hole 22 of the power terminal and the power terminal. The terminal output hole 23; the motherboard 1 is also provided with a positive pole hole 31 and a negative pole hole 32, which form a connection hole pair 3. All connection holes on the motherboard are tightly embedded with conductive rings 5, and an insulating ring 4 is...

Embodiment 2

[0029] Figures 6 and 7 show that the structure of this example is basically the same as that of Example 1, the only difference is that the conductive ring 5 of this example is not a monolithic structure, but is composed of sections: the power is correct The conductive ring 5 on the polar hole 21 and the positive hole 31 is tightly connected by the upper and lower sections and the part where the positive plate 12 extends into the two sections to form a conductive ring 5 electrically connected to the positive plate 12; and the power The conductive ring 5 on the terminal negative polarity hole 22 and the negative hole 32 is closely connected by the upper and lower sections and the embedded part where the negative plate 14 extends between the two sections to form a conductive ring electrically connected to the negative plate 14 5. In the process of bonding and pressing each layer of material into a laminated busbar, the segmented conductive ring 5 can be conveniently assembled on ...

Abstract

The present invention relates to a cascade power bus bar for maglev train maglev choppers. An insulating top plate, a conductive positive plate, an insulating partition plate, a conductive negative plate and an insulating bottom plate are orderly stacked and bonded to form a motherboard. A power end connecting hole group adaptive to a power end of a power module is arranged on the motherboard, wherein, the power end connecting hole group comprises a power end positive polarity hole, a power end negative polarity hole and a power end output hole; a positive hole and a negative hole are also arranged on the motherboard and form a connecting hole pair; conducting rings are respectively inlayed in all connecting holes on the motherboard; the power end positive polarity hole, the positive hole and the negative plate of the motherboard are separated by insulating rings; the power end negative polarity hole, the negative hole and the positive plate are separated by insulating rings; the power end output hole, the positive plate and the negative plate are also separated by insulating rings. The cascade power bus bar has the advantages of ensuring few connecting lines in maglev choppers, occupying small space, having low installation and maintenance cost as well as good heat dissipation of power devices, effectively inhibiting mutual interference among devices and improving the reliability of maglev train maglev choppers.

Description

technical field [0001] The invention relates to a power bus bar used by a levitation chopper of a maglev train. Background technique [0002] The levitation chopper of the maglev train is an important part of the control system of the maglev train, and it is the key to ensure the normal levitation height of the maglev train, thereby ensuring the normal operation of the maglev train. The power module in the chopper of the maglev train, such as the insulated gate bipolar transistor (IGBT) module, is an indispensable key device in the chopper. During the use of the power module, it also needs to be connected with other components such as power supply and large capacitor. At present, the connection mode between the power module and other components in the suspension chopper is usually connected by wires and terminals. This method has the following problems: (1) Due to the large number of power terminals of multiple power modules, the number of wires to be connected is large, a...
