Description
Technical field
The utility model belongs to power inverter technical field of filtering, and in particular to a kind of permanent magnet generator unit inversion filtering group
It attaches together and puts.
Background technology
Mobile power be it is a kind of facilitate portable portable power supply, popularization and rapid growth with digital product are mobile
Power supply is also increasingly closer with our daily life.For military use product, the Electro Magnetic Compatibility of mobile power will
Ask especially harsh.Mobile power is generally mostly generated electricity using permanent magnet generator, and the power quality qualification rate of output is relatively low, therefore
For output quality qualification power supply, it is necessary to install the electric power for the inferior quality that inversion rectification module sends permanent magnet generator additional, pass through
AC-DC-exchange is crossed, is made into the higher electric power of quality.But the inversion rectification module installed additional can generate complicated electromagnetism and do
It disturbs so that the electric power of final output influences whether the normal use of other equipment.To solve the above-mentioned problems, in the prior art
In, the method for use is to increase a power-supply filter in power output end, carries out elimination interference by power-supply filter, still
Inversion rectification module and filter module generally use are installed separately form in the prior art, this allows for the generation of inversion rectification module
Radiation interference All other routes and filter module are polluted again by cable.Therefore, it is necessary to provide a kind of inversion
The box body structure of combination is filtered, the Conduction Interference on power cord and radiation interference are eliminated in box body simultaneously, it is dry to reduce radiation
Disturb the risk polluted again.
Utility model content
The utility model in order to make up deficiency of the prior art, provide it is a kind of simple in structure, easy to use, can not only
It is enough to eliminate the Conduction Interference on power cord and radiation interference in box body simultaneously, the risk that radiation interference pollutes again is reduced,
But also it disclosure satisfy that the permanent magnet generator unit inversion filtering combination unit of Electro Magnetic Compatibility index request.
What the technical solution of the utility model was realized in：
A kind of permanent magnet generator unit inversion filtering combination unit, it is characterised in that：Including metal case, the metal case
External one side is equipped with shielding connector, and opposite side is equipped with ground wire；The metal case is internally provided with intermediate bulkhead, the centre
Partition plate is while be filter module, another side is inversion rectification module；The metal case upper surface is milled with sulculus, on the sulculus
Correspondence is equipped with conductive rubber strip；Metal box-lid is additionally provided in the metal case.
As a kind of perferred technical scheme, the metal case is an integral molding structure.
As a kind of perferred technical scheme, the metal box-lid is well fastened with metal case by bolt.
By adopting the above-described technical solution, it compared with prior art, has the advantages that：By inversion rectification module
It is combined with filter module, forms a complete electromagnetic armouring structure body, effectively solve inversion rectification module to it
The radiation interference of its module is met with having on the power-supply device of harsh Electro Magnetic Compatibility index request, solves equipment hardly possible
With by problem.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
A kind of permanent magnet generator unit inversion filtering combination unit as shown in Figure 1, 2, mainly includes metal case 1, conduction
Rubber strip 2, metal case 3, inversion rectification module 4, filter module 5, shielding connector 6, ground wire 7, intermediate bulkhead 8, sulculus 9
With bolt 10.Metal case 3 is an integral molding structure, and metal case 3 is divided into two compartments by intermediate bulkhead 8；In metal case 3
Surface mills out sulculus 9, and conductive rubber strip 2 is mounted in sulculus 9；Metal case 3 is carried out good with metal box-lid 1 by bolt 10
Good fastening, metal box-lid 1 form a complete electromagnetic armouring structure body with metal case 3, can close inside metal case 3
Electronic device work when the field radiation interference that generates, and discharged by 3 external ground line 7 of metal case.
Operation principle：The intermediate frequency three-phase that permanent magnet generator is sent（380V、400Hz）Electric power in metal case 3 by installing
Shielding connector 6, after entering inversion rectification module 4, output single-phase power frequency（230V、50Hz）Electric power, the power supply after inversion
Some High-frequency Interferences brought by inversion rectification module 4 can be mixed on line, therefore the power cord after inversion rectification is using filtering
Module 5 exports the electric power for meeting electromagnetic compatibility standard, supply arrangement end after filtering out interference.So far, the present utility model purpose
It is accomplished.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modifications, equivalent replacements and improvements are made should be included in the utility model
Protection domain within.
