Description
Technical field
The present invention relates to composite bus bar, is specially a kind of subway permanent magnetism traction inversion chopped power module composite bus bar.
Background technology
The power device of high power frequency conversion power supply is in switching process, due to from DC energy storage capacitance between IGBT device
Dc bus on stray inductance and IGBT module own inductance influence, can produce very high peak voltage, this spike,
It can make to increase by the electric current of device, ultimately result in device overheat, or even make IGBT out of control sometimes and exceed the specified peace of device
Full workspace and damage.This risk is tackled, the general electrical connection that power device is carried out using composite bus bar, can so subtract
Influence of the stray inductance to power device in small circuit.
Composite bus bar is usually to be made of copper bar, insulating layer and dielectric film, and electric current is bigger, and copper bar weight is heavier.According to electricity
The minimizing of power electronic inverter, high-power trend, the design of composite bus bar also aggravate therewith.Notably one piece of composite bus bar is often
The electrical connection of multiple functions conversion occurs, this designs and install especially inconvenient for composite bus bar.Due to main circuit work(
The requirement that can be concentrated, the electrical connection of composite bus bar also need to meet the requirement, and one piece of composite bus bar generally requires to meet a variety of work(
Can, while take into account and flow the features such as effect is good, temperature rise is low and inductance is small so that the design and structure of composite bus bar are also more and more multiple
It is miscellaneous, while also can increasingly weigh.
The content of the invention
The present invention is in order to solve the problems, such as that existing composite bus bar there are heavier-weight, complicated and installation are inconvenient, carries
A kind of subway permanent magnetism traction inversion chopped power module composite bus bar is supplied.
The present invention adopts the following technical scheme that realization：Subway permanent magnetism draws inversion chopped power module composite bus bar,
Four pieces of rectangular-shaped inversion output busbars and four pieces of inversion direct current busbars including connection corresponding with four groups of inversion circuit power devices,
Rectangular-shaped copped wave resistance busbar and copped wave DC master row, the Support Capacitor busbar being connected with copped wave power loop device, inversion are defeated
Go out busbar to be made of three pieces of rectangular-shaped copper bar bodies fixations, and the upper end of every piece of copper bar body is both provided with phase inversion output
Terminal, copped wave resistance busbar are made of one piece of rectangular-shaped copper bar body, and copped wave resistance busbar upper end is provided with copped wave output
Screw shell, Support Capacitor busbar and inversion direct current busbar are both provided with terminal, inversion direct current busbar and copped wave DC master row
It is vertically arranged, and one end of Support Capacitor busbar is provided with the bolt plate coordinated with screw shell, Support Capacitor busbar
The other end is provided with two dc bus positive terminals and a dc bus negative terminal.
Monoblock composite bus bar is divided into the single busbar of five classes, by the assembling of single busbar by direct-flow input circuit,
The main circuits such as IGBT, diode, Support Capacitor link together, and disclosure satisfy that the convenience of installation and the compactedness of layout, together
When full power current exports, overall temperature rise is not more than 13.7K, meets design the needs of being less than 30K, to overcome existing compound
There are the problem of heavier-weight, complicated and installation inconvenience for busbar.
The present invention is reasonable in design reliable, integrally alleviates the weight of composite bus bar, reduces loop inductance, improves
The reliability of IGBT work, and reduce composite bus bar processing, carry, the difficulty of installation and removal, there is simple in structure, drop
Low production difficulty and the advantages of save cost.
