Description
Technical field
The utility model belongs to High Power Medium Voltage Variable Frequency Technology field, the low sense insulated power busbar knot of especially a kind of lamination
Structure.
Background technology
In High Power Medium Voltage Variable Frequency Technology field, the apparatus structure needed is more and more compacter, and this requires in apparatus structure
It is upper to realize that maximized structure space utilizes.Using three level Large Power medium-pressure frequency conversion devices of IGCT devices, portion in the device
Electric energy exchanges transmission link, as devices switch frequency improves, the higher hamonic wave of generation and stray inductance phase present on circuit
Effect can make IGCT output ends generate overvoltage, IGCT over-voltage breakdowns can be made when serious, although can install shutdown absorbs electricity
Road, the stray inductance for effectively reducing commutation circuit are most effective solution.Reduce just, zero, the distance between negative conductor, can
Effectively reduce the stray inductance of circuit.
Currently, in practice, generally use just, zero, method that insulating materials is padded between negative conductor, reduce alternate
Away from.But there are insulating layer positioning to be not allowed, but conducting medium is easy, by such environmental effects, to lead to failure of insulation.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide a kind of lamination low sense insulated power mother
Cable architecture.
The utility model solves its technical problem and following technical scheme is taken to realize：
A kind of low sense insulated power bus structure of lamination, it is characterised in that：Including multiple laminations being cascading,
Pressing device is installed outside multiple laminations of stratification position；The stacking contact position of lamination is coated with insulating layer.
Moreover, the conductive end at lamination both ends stretches out insulating layer and is formed with bending, it is formed on conductive end for installing
The mounting hole of fixing bolt.
Moreover, the pressing device is made of gasket and screw, it is equal outside the insulating layer of top layer and lowest level lamination
One gasket is installed, exceed the outer of insulating layer in the outer of gasket both lateral sides and is formed with screw hole, the pad of corresponding position
Mounting screw in piece screw hole.
Moreover, positive lamination, zero pole lamination and cathode lamination that the multi-layer stacks are cascading.
The advantages of the utility model and good effect are：
1, the stratification position of each lamination of the utility model uses sheet insulating materials, passes through dedicated mold pressure
Technique is closed, encapsulation will be coated by tin plating copper plate, after plastic packaging coats, conducting medium becomes an entirety with insulating materials,
Conducting medium is completely isolated with the external world, no longer by such environmental effects.
2, this structure makes no longer to be subjected to displacement between conducting medium and insulating materials, it is ensured that Insulation Coordination no longer changes.
3, n phase conductor close parallel fitting of the utility model Jing Guo insulation-encapsulated, effectively reduces the stray inductance of circuit,
Ensure that Insulation Coordination no longer changes, no longer by such environmental effects, extends the service life of single unit system.

Often work, extends the service life of single unit system.
Multi-lamination structure shown in the present embodiment is laminated by positive lamination 1, zero pole lamination 2 and cathode lamination 3 three
Piece is sequentially overlapped composition, and lamination internal layer is conducting medium layer, using tin plating copper plate material, by dedicated in the middle part of lamination
Sheet insulating materials plastic packaging is coated on outside lamination and forms insulating layer by die pressing apparatus, and the conductive of the upper/lower terminal of lamination is situated between
Matter layer stretches out outside insulating layer and is formed with bending；
One pressing device is installed in the middle part of three laminates, is equipped with outside the zero pole lamination and cathode lamination of lower part another
One pressing device.
Exchange transmission link in internal electric energy, by insulating wrapped encapsulation just, zero, the conductors of minus three laminates can be close
Fitting, effectively reduce the stray inductance of circuit, effectively reduce impact of the higher hamonic wave overvoltage to electric appliance original paper, ensure system
Normal work, extends the service life of single unit system.
Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with
