Description
Technical field
The present invention relates to composite bus bar, be 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 between DC energy storage electric capacity to IGBT device
Dc bus on stray inductance and the impact of IGBT module own inductance, can produce the highest peak voltage, this spike,
Can make to be increased by the electric current of device, ultimately result in device overheated, the most sometimes make IGBT out of control and exceed the specified peace of device
Full working area and damage.Tackle this risk, the general electrical connection using composite bus bar to carry out power device, so can subtract
The impact on power device of the stray inductance in little circuit.
Composite bus bar is usually and is made up of copper bar, insulating barrier and dielectric film, and electric current is the biggest, and copper bar weight is the heaviest.According to electricity
The miniaturization of power electronic inverter, high-power trend, the design of composite bus bar increases the weight of the most therewith.Notably one piece of composite bus bar is often
There will be the electrical connection that several functions converts, this is for composite bus bar design and installs inconvenient especially.Due to main circuit merit
The requirement that can concentrate, the electrical connection of composite bus bar also needs to meet this requirement, and one piece of composite bus bar generally requires and meets multiple merit
Can, the feature such as simultaneously take into account that current-sharing is effective, temperature rise is low and inductance is little so that design and the structure of composite bus bar are more and more multiple
Miscellaneous, simultaneously also can be more and more heavier.
Summary of the invention
The present invention is to solve that existing composite bus bar exists heavier-weight, structure is complicated and installs inconvenient problem, carry
A kind of subway permanent magnetism has been supplied to draw inversion chopped power module composite bus bar.
The present invention adopts the following technical scheme that realization: subway permanent magnetism draws inversion chopped power module composite bus bar,
Including four piece rectangular-shaped inversions output busbars connecting corresponding with four groups of inversion circuit power devices and four pieces of inversion direct current busbars,
The rectangular-shaped copped wave resistance busbar being connected with copped wave power loop device and copped wave DC master row, Support Capacitor busbar, inversion is defeated
Go out busbar to be formed by three pieces of rectangular-shaped copper bar bodies are fixing, and the upper end of every piece of copper bar body is provided with a phase inversion output
Terminal, copped wave resistance busbar is made up 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 it is provided with on 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 five single busbars of class, by the assembling of single busbar by direct-flow input circuit,
The main circuits such as IGBT, diode, Support Capacitor link together, it is possible to meet the convenience and the compactedness of layout installed, with
Time when full power current exports, overall temperature rise is not more than 13.7K, meets the design demand less than 30K, overcomes existing compound
There is heavier-weight in busbar, structure is complicated and installs inconvenient problem.
Present configuration is reasonable in design reliably, and entirety alleviates the weight of composite bus bar, reduces loop inductance, improves
The reliability of IGBT work, and reduce the difficulty that composite bus bar is processed, carried, mounts and dismounts, there is simple in construction, fall
Low production difficulty and the advantage provided cost savings.
