Abstract
The utility model provides a special type current transformer with high -efficient heat dispersion, includes the casing, be equipped with the troidal core in the casing, the coiling has a primary coil on the troidal core, primary coil's left side laminating has the fin, the fin includes central fin, fixes being equipped with the first bar fin of a plurality of on the central fin, has evenly arranged the long strip fin of a plurality of seconds on the first long strip fin, and the surface of first long strip fin and the long strip fin of second all is the unevenness form. The beneficial effects of the utility model are that the setting up of first long strip fin and the long strip fin of second makes heat radiating area greatly increased, has effectively improved the radiating effect, simultaneously the surface of first long strip fin and the long strip fin of second all is unevenness and describes and make the further increase of heat radiating area, has further improved the radiating effect.
Description
Technical field
This utility model is related to current transformer technical field, and in particular to a kind of special type electricity with high efficient heat dissipation performance
Current transformer.
Background technology
Current transformer principle is according to made by electromagnetic induction principle.Current transformer is by the iron core and winding for closing
Composition.Its first side winding number of turn seldom, is gone here and there in the circuit of electric current of measurement is needed, therefore its Jing often has the whole of circuit
Electric current flows through, and secondary side winding turn ratio is more, is serially connected in measuring instrumentss and protective loop, current transformer operationally,
Its secondary side circuit is to close all the time, therefore the impedance very little of measuring instrumentss and protective loop series coil, Current Mutual Inductance
The working condition of device is close to short circuit.Current transformer is that primary side high current is converted into secondary side small current to measure, secondary
Can not open a way side.
Chinese patent（CN204215892U）Disclose a kind of extraordinary current transformer, the patent utilization thermoelectric module and
The purpose that heat pipe is fitted together to fin to realize radiating, but the area of dissipation of the chimeric fin of heat pipe is effective, it is difficult to realize good
Radiating effect, the heat that current transformer is operationally produced still timely and effectively cannot be scattered and disappeared.Therefore, for existing
There is the deficiency of technology, need badly and a kind of current transformer of good heat dissipation effect is provided.
Utility model content
The purpose of this utility model is to provide a kind of extraordinary current transformer with high efficient heat dissipation performance, with solution
The problem proposed in stating background technology.
For achieving the above object, this utility model provides following technical scheme：
A kind of extraordinary current transformer with high efficient heat dissipation performance, including housing, is provided with annular core in the housing,
Primary winding is wound with annular core, fin is fitted with the left of the primary winding, and the fin includes center wing
Piece, is fixed with several the first strip fins on central fins, be evenly arranged some second length on the first strip fin
The surface of strip fin, the first strip fin and the second strip fin is in roughness.
As further program of the utility model：The fin is in flat structure.
As this utility model further scheme：The first strip fin is provided with three altogether, and in radiation
Shape is arranged on central fins.
As this utility model further scheme：The first strip fin and some second strip fin shapes
Into rich font.
The beneficial effects of the utility model are that the setting of the first strip fin and the second strip fin causes radiating surface
Product is greatly increased, and effectively increases radiating effect；The surface of the first strip fin and the second strip fin is in recessed simultaneously
It is convex not flat-shaped so that area of dissipation further increases, further increase radiating effect.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1 and Fig. 2 is referred to, in this utility model embodiment, a kind of extraordinary Current Mutual Inductance with high efficient heat dissipation performance
Device, including housing 1, is provided with annular core 2 in the housing 1, is wound with primary winding 3, the primary winding on annular core 2
3 left side is fitted with fin 4, and the fin 4 includes central fins 401, be fixed with central fins 401 several
One strip fin 402, has been evenly arranged some second strip fins 403, the first strip wing on the first strip fin 402
The surface of piece 402 and the second strip fin 403 is in roughness, the first strip fin 402 and the second strip wing
The setting of piece 403 causes area of dissipation to greatly increase, and effectively increases radiating effect；Simultaneously the first strip fin 402 and the
The surface of two strip fins 403 causes area of dissipation further to increase in roughness, further increases radiating
Effect.
The fin 4 is in flat structure.
The first strip fin 402 is provided with three altogether, and is radially arranged on central fins 401.
The first strip fin 402 and some second strip fins 403 form rich font.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type is by claims rather than described above is limited, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in this utility model.Any reference in claim should not be considered as restriction
Involved claim.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of description is only that those skilled in the art should for clarity
Using description as an entirety, the technical scheme in each embodiment can also Jing it is appropriately combined, form those skilled in the art
Understandable other embodiment.
