System can measure output, its mainly include AC-DC, direct current become alternating current and direct current inversion of direct current isotype, have strong power part with
Weak current part, the mode of both utilization spaces stacking carries out strong and weak electric isolution, but electric isolating effect is poor, and electromagnetic interference is tight
Weight, the accuracy of influence weak current part control, function and power fixed structure adaptive faculty are weak；And, strong power part and light current portion
Mutually covering is overlapping for split-phase, causes that maintenance difficulty is big, radiating effect is poor, has a strong impact on the life-span of product.In addition, existing unsteady flow mould
Block does not account for taking the demagnetization mode of internal electromagnetic compensation, so as to cause further to produce larger unhelpful electromagnetic wave.
The content of the invention
Simple and reasonable for structure it is an object of the invention to provide one kind, strong and weak electric isolating effect is good, internal electromagnetism supplement subtracts
The generation of few unhelpful electromagnetic wave, using office of planarization method portion, is conducive to the spelling group unsteady flow modular structure for radiating and safeguarding, with gram
Take the deficiencies in the prior art.
The object of the present invention is achieved like this：
A kind of spelling group unsteady flow modular structure, including weak current part and strong power part, weak current part are provided with light current bus, forceful electric power
Part is provided with forceful electric power bus, it is characterised in that：The weak current part and strong power part plane distribution, weak current part and strong power part
Between separated by metallic shield wall, light current bus and forceful electric power bus, light current bus is consistent with the sense of current of forceful electric power bus；Institute
State strong power part and be provided with multiple internal currents and take the shape of the letter U the unsteady flow submodule of direction flowing, unsteady flow submodule combines to form different work(
The change flow module of rate.
The purpose of the present invention can also be solved using following technical measures：
Used as more specifically scheme, the multiple unsteady flow submodule is respectively AC-DC submodule, direct current and becomes exchange
Submodule, direct current inversion of direct current submodule.
The multiple unsteady flow submodule is arranged along forceful electric power bus directional combination.
Laid on the metallic shield wall to being applied to the radiator fan of strong power part unsteady flow submodule cooling, radiation air
The blowing direction of fan points to strong power part.
Used as more specifically a kind of scheme, the change flow module becomes flow module, multiple changes of its strong power part into welding machine
Stream submodule includes that the AC-DC submodule arranged successively along forceful electric power bus current direction, direct current become exchange submodule
With secondary AC inversion of direct current submodule, one time AC-DC submodule, direct current become exchange submodule and secondary AC inversion of direct current
Submodule internal current take the shape of the letter U direction flowing.
Used as more specifically another scheme, the change flow module becomes flow module into electrical equipment, its strong power part
Multiple unsteady flow submodules include that the direct current inversion of direct current submodule arranged successively along forceful electric power bus current direction and multiple direct currents become and hand over
Stream submodule, direct current inversion of direct current submodule and each direct current become and exchange submodule internal current and take the shape of the letter U direction flowing.
The electrical equipment is electric automobile.
The electrical equipment is elevator.
Beneficial effects of the present invention are as follows：
（1）Such strong, weak electricity part for becoming flow module is distributed using planarization method, meanwhile, strong, weak electricity part is by total
Line and metallic shield wall separate, and can realize good anti-tampering isolation（Anti-electromagnetic-radiation high）；
（2）In such change flow module the unsteady flow submodule internal current of strong power part take the shape of the letter U direction flowing, according to faraday
The law of electromagnetic induction understands that the electromagnetism produced by the both sides electric current of the U-shaped sense of current is in opposite direction, so as to realize that internal electromagnetism is mended
Repay, to reduce the generation of unhelpful electromagnetic wave；
（3）Because heat is smaller produced by weak current part, after strong, weak electricity part is using planarization method distribution, Ke Yi
Each unsteady flow submodule of correspondence strong power part installs radiator fan, and the encapsulation of unsteady flow submodule in one on metallic shield wall,
Concentrate radiating；
（4）After such strong, weak electricity part for becoming flow module is using planarization method distribution, saving takes up room, and maintenance
Install more convenient.
