Specific embodiment
Describe the exemplary embodiment of the utility model embodiment in detail below in conjunction with the accompanying drawings.
In exemplary embodiment of the present utility model, describe to carry herein as a example by applying the power model in current transformer
The structure of the power model for going out.It will be understood that, the utility model proposes the structure of power model be applied to and any meet
The power model of structure defined in this, is not limited solely to the power model in current transformer.
1~Fig. 4 of reference picture, according to exemplary embodiment of the present utility model, a kind of power model includes reactor module
1st, power device 2, be connected plate 4 and heat-proof device 3.Wherein, reactor module 1 and power device 2 respectively be connected
Plate 4 is connected, and the mode that be able to can be arbitrarily realized for example, by bolt or welding etc. consolidates reactor module 1 and power device 2
It is fixed to being connected on plate 4.Heat-proof device 3 is set between reactor module 1 and power device 2.
The present embodiment provide power model by between reactor module 1 and power device 2 set heat-proof device 3,
The heat that reactor module 1 is sent separates with power device 2 so that power device 2 is not at work by the warm of reactor module 1
The interference of amount, it is ensured that the normal operation circumstances of power device 2.
Alternatively, reactor module 1 and power device 2 are separately positioned on the both sides of the plate 4 that is connected, in the plate that is connected
4 side, or/also, opposite side is provided with heat-proof device 3, i.e., being connected between plate 4 and reactor module 1, or/
Also, heat-proof device 3 is provided between plate 4 and power device 2 being connected.
Alternatively, heat-proof device 3 can be at least one in heat insulation foam, cooled plate and isolation air channel, for intercepting
The heat that reactor module 1 sends, makes heat successfully cannot be absorbed by power device 2, which reduces reactor mould
Influence of the heat that block 1 sends to power device 2.
Following formula shows heat radiation principle：
Q=Qr+Qa+Qd
Wherein, Q is the total amount of heat that heat generating components is produced, QrIt is reflection heat, QaTo absorb heat, QdIt is to pass through heat.
As can be seen that if necessary to reduce transmission heat Q of the reactor module 1 through heat-proof device 3d, then should improve every
The reflection heat Q of thermal 3rAnd/or absorb heat Qa.Because heat insulation foam has high temperature resistant, nonflammable, thermal conductivity factor low
Advantage, therefore when using heat insulation foam as heat-proof device 3, the heat that most of reactor module 1 discharges is by heat insulation foam with anti-
Penetrate heat QrForm intercept, remaining a part of heat can be by heat insulation foam own absorption, extremely least a portion of heat diffusion to work(
On rate device 2.
The heat insulation foam that the utility model embodiment will be commonly used to automotive field is applied in the power model of current transformer,
Certain buffer action can be played to the heat of the release of reactor module 1, the temperature rise that can effectively reduce power device 2 is asked
Topic, it is to avoid frequently change because of high temperature failure the problem of power device 2.
Heat insulation foam can be set according to expected effect of heat insulation and the distance between reactor module 1 and power device 2
Thickness.In a kind of optional implementation method, the thickness of heat insulation foam is 2mm~10mm.If the thickness of heat insulation foam is too small, very
Difficulty plays a part of to completely cut off the heat of the release of reactor module 1.If the thickness of heat insulation foam is excessive, difficulty is brought to installation.
Heat-proof device 3 can also be cooled plate or isolation air channel, the cold water soaking reactor module 1 that cooled plate passes through circulation
The heat of release simultaneously takes power model out of in time, to reduce the temperature of the surrounding environment of power device 2；Isolation air channel will by air-flow
The heat that reactor module 1 is discharged is taken away in time.
Alternatively, power device 2 can be direct current support capacitor.Direct current support capacitor also known as DC-Link capacitors,
Smothing filtering mainly is carried out to voltage in current transformer, it has the features such as proof voltage is high, resistance to electric current is big, capacity loss is small；
Alternatively, power device 2 can also be the other components in power model.
Illustrated with example below heat insulation foam in power model direct current support capacitor temperature rise influence, do not install additional every
Before hot cotton, reactor module 1 and DC support electric capacity are separately mounted to be connected the both sides of plate 4, the release of reactor module 1
Heat is radiated on DC support electric capacity easily through the plate 4 that is connected.Now, the temperature rise of DC support electric capacity is at 23 DEG C,
Critical condition in can normally use.It is heat-insulated after heat insulation foam is installed additional between reactor module 1 and direct current support capacitor
Cotton plays certain buffer action to the heat that reactor module 1 is discharged, additionally it is possible to absorb the heat of sub-fraction, makes only few
Partial heat is through heat insulation foam and is radiated on direct current support capacitor.The heat of reactor module 1 is reduced to direct current branch
The influence of electric capacity is supportted, the temperature rise of DC support electric capacity reduces 5 DEG C, now the operating ambient temperature of DC support electric capacity is being allowed
Within the scope of, the steady operation of DC support electric capacity is so not only ensure that, service life is also increased, solve due to straight
The problem that stream Support Capacitor needs frequent replacing due to the overheat damage for causing.
Alternatively, reactor module 1 has thermal component 5, and reactor module 1 itself also has certain wanting to heat dispersion
Ask, its most of heat for producing is radiated by thermal component 5, and a remaining part is then to diffuse into surrounding environment, is entered
Row radiating.
Further, thermal component 5 can be water-cooling part or wind-cooling heat dissipating part.For example, can be by cooling water
Pipe ring is placed in the line bag of reactor module 1 around reactor module 1 or by cooling water pipeline, the heat of reactor module 1
Amount is derived by aqueous medium, and the purpose of temperature rise is reduced to reach.
Alternatively, the plate 4 that is connected can be aluminum plate, be mainly used in constant reactance device module 1 and power device 2；Even
It can also, with certain degree of hardness, can play a part of to fix the sheet material of other materials to connect fixed plate 4.
