Raw higher due to voltage spikes, produces certain impact to device for power switching, affects device for power switching
Life-span, thus reduce the reliability of power cell.
In prior art, in order to overcome the problem that common busbar stray inductance is bigger, it is common that commonly
Busbar surface puts heat-shrink tube.
But, prior art has following defects that heat-shrink tube is thermoplastic, and temperature resistant grade is relatively low,
Being heated and be easily deformed, insulating reliability is poor, and the most easily burns, and there is potential safety hazard.
Summary of the invention
The present invention provides a kind of high pressure hot compress busbar, reliable in order to solve insulation present in prior art
Property is poor, the problem that there is potential safety hazard.
The invention provides a kind of high pressure hot compress busbar, including:
For connecting the busbar of each device in turning circuit；
The insulating barrier that described busbar surface cover heating solidity insulating powder solidify to form, described insulating barrier is used
In making described busbar and external insulation, the thickness of described insulating barrier is more than or equal to setting thickness.
The high pressure hot compress busbar that the present invention provides, by solid at busbar surface cover heating solidity insulating powder
Changing the insulating barrier formed so that busbar and external insulation, this insulating barrier is high temperature resistant, and safety is good, and
And and the bonding force of busbar, compactness strong, it is ensured that the reliability of insulation, the thickness of this insulating barrier is big
In or equal to set thickness so that the insulation that busbar can withstand up to volt up to ten thousand is pressure.
Accompanying drawing explanation
The structural representation of high pressure one embodiment of hot compress busbar that Fig. 1 provides for the present invention.
Detailed description of the invention
Below by specific embodiment and accompanying drawing, technical scheme is done the most in detail
Describe.
The structural representation of high pressure one embodiment of hot compress busbar that Fig. 1 provides for the present invention.Such as Fig. 1
Shown in, this high pressure hot compress busbar includes: for connecting the busbar 11 of each device in turning circuit；
The insulating barrier 12 that busbar 11 surface cover heating solidity insulating powder solidify to form, insulating barrier 12
For making busbar 11 and external insulation, the thickness of insulating barrier is more than or equal to setting thickness.
Concrete, this heat cured insulation powder can be the thermosets of 100%, thermosets
Having electrical insulating property, impact resistance and the abrasion resistance of excellence, adhesive force is good, high temperature resistant, can bear
Temperature range can reach between-30 DEG C ~ 180 DEG C.Described setting thickness can be 1.5mm.Can
Choosing, insulating barrier 12 can be formed by electrostatic molding powder hot setting, i.e. forms the thermosetting of insulating barrier 12
Property insulating powder can be electrostatic molding powder.
This heat cured insulation powder can use the techniques such as spraying (such as electrostatic spraying) to cover busbar
The surface of 11, concrete, the whole surface of busbar 11 all can be covered insulating powder, or,
Insulating powder can also be covered on busbar 11 surface in addition to the junction except device each with turning circuit
End, i.e. can cover insulating powder by the portion other than connected portion on busbar 11 surface.The most again to this thermosetting
Insulating powder carries out hot setting, and insulating powder can produce cross-linking reaction and generate certain with busbar 11
Chemical bond, i.e. can fuse into one with busbar 11.
The thickness of the heat cured insulation powder covered can spray, such as according to the actual requirements: permissible
Use the voltage strength in environment according to busbar 11, the thickness of the heat cured insulation powder covered is sprayed
It is painted with 1.5mm so that busbar can meet the resistance to pressure request of 12kV, can be 12kV at insulation voltage
Under realize 1 minute not flashover or puncture, be therefore easy between high pressure hot compress busbar with interval less away from
From being overlapped, the space of more than 30% can be saved, be greatly saved installing space, it is to avoid sky
Between waste, reduce the volume of whole product.
The high pressure hot compress busbar that the present embodiment provides, owing to forming the heat cured insulation powder of insulating barrier 12
End has resistant to elevated temperatures feature, so safety is good；And be different between heat-shrink tube and busbar 11
Simply simple physical bond (heat shrinkable is easily deformed), heat cured insulation powder is through high temperature
Solidification, can produce cross-linking reaction and generate certain chemical bond with busbar 11, and busbar 11 fuses into one,
Gap, bonding force and compactness is had no strong, it is ensured that insulation between insulating barrier 12 and busbar 11
Reliability, thus reduce the stray inductance of busbar 11, during contactor, will not open
Close that device (such as insulated gate bipolar transistor) is upper produces higher due to voltage spikes, it is to avoid split
Close device and produce impact, and the impact on switch device lifetime；Thickness of insulating layer is more than or equal to
Set thickness (1.5mm) so that busbar 11 can withstand up to the insulation pressure (12kV) of volt up to ten thousand,
Conveniently it is applied in high tension loop, simultaneously facilitates and fold with the less distance in interval between busbar 11
Add, not only increase space availability ratio, and further reduce the stray inductance in whole loop.
The high pressure hot compress busbar that the present embodiment provides, owing to the thickness of insulating barrier is more than or equal to setting
Thickness, therefore can apply in environment under high pressure, such as in train auxiliary electrical system, the most permissible
In power cell for train auxiliary electrical system etc..
Optionally, the busbar 11 in embodiment illustrated in fig. 1 may include that naked metal is arranged.Optionally,
Naked metal row can be naked copper row or naked aluminum row.Naked metal row surface can cover coating, and this coating is used
In preventing naked metal row surface to be corroded, can cover at naked metal row surface and each device in turning circuit
The junction of part.Optionally, the coating that naked metal row surface covers can be tin coating or nickel coating,
First naked metal can be discharged into row pickling, will arrange in the aqueous solution immersing sulphuric acid etc., to remove by naked metal
Go the thin film such as oxide on naked metal row surface, the most tin plating or nickel plating.Concrete, can basis
The occasion that busbar 11 uses, selects at naked metal row's plating nickel on surface or tin plating to prevent naked metal from arranging
Surface is corroded.Such as: after naked metal row's plating nickel on surface, being operated in air and alkali liquor, chemistry is steady
Qualitative good, the most easy to change, more than 600 degrees Celsius could be oxidized, it is easy to polishing, surface-brightening.
And after naked metal row's electroplating surfaces with tin, owing to heat conduction, the electric conductivity of stannum are good, therefore, it can reduce
Busbar 11 and the contact resistance of the junction of each device in turning circuit, reduce the amplitude that temperature raises；
Further, stannum is the most soft ductile, and welding performance is good, can prevent scratch, and electromagnetism interference is strong,
Chemical stability is higher, sulphuric acid, nitric acid, hydrochloric acid weak solution in dissolve hardly.
Last it is noted that various embodiments above is only in order to illustrate technical scheme, rather than
It is limited；Although the present invention being described in detail with reference to foregoing embodiments, this area
Those of ordinary skill is it is understood that the technical scheme described in foregoing embodiments still can be entered by it
Row amendment, or the most some or all of technical characteristic is carried out equivalent；And these amendment or
Person replaces, and does not make the essence of appropriate technical solution depart from the model of various embodiments of the present invention technical scheme
Enclose.
