This reactor utilizes the spring card and the flexible liner of C shape tightly to wrap up the iron core piece, and the combination that has increased the iron core piece is closely spent, improves the uniformity of reactor, has adopted the narrower iron core piece of three rows to fix through the fine glass fiber of insulating nature and has bondd together, has reduced the width of this reactor iron core, has reduced eddy current loss.
Description
Technical field
This utility model relates to electronic device field, relates in particular to a kind of low eddy-current loss reactor.
Background technology
Reactor is the solenoid form that is coiled into by wire, and is inserted into iron core at solenoid, to obtain bigger inductance.Reactor is mainly used to limiting short-circuit current, also has in wave filter with capacitor serial or parallel connection for the higher hamonic wave limiting in electrical network.
Iron core many employings stalloy of existing reactor is manufactured into lamellar, then is bonded together by binding agent, is inserted in the coil of reactor.The lamination of this type of reactor is wider, and the eddy-current loss causing reactor is big, and easily produces high temperature, reduces the service life of reactor.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of low eddy-current loss reactor, the lamination of long and narrow lamellar is wrapped by arranging the spring card of two C-shapeds in reactor skeleton, to reach to be greatly lowered reactor eddy-current loss, and prevent the purpose of high temperature.
For achieving the above object, the technical scheme that this utility model offer is following: a kind of low eddy-current loss reactor, it is characterized in that: described low eddy-current loss reactor includes that center is provided with the skeleton of through hole, skeleton side is wound with coil, and coil two stretches out lead-out wire, two the most identical spring cards of shape and size it are provided with at frame center, the cross section of spring card is C-shaped, and two spring card indentation, there be oppositely arranged, one layer of flexible liner it is equipped with inside two spring cards, in spring card, card has the lamination of the three compact arranged long and narrow lamellars of row, lamination is the most all by the fixing bonding of glass fibre, lamination is less than the stalloy manufacture of 0.2 by thickness.
As the further optimization of the technical program, described skeleton is manufactured by PVC plastic.
As the further optimization of the technical program, described coil is manufactured by copper cash.
As the further optimization of the technical program, described spring card is by the spring steel manufacture that the trade mark is 3Cr13Mo, and flexible liner is by the fixing bonding of high temperature resistant glue and spring card.
As the further optimization of the technical program, described flexible liner is manufactured by insulating resin, and flexible liner and lamination interference fit.
Above technical scheme is used to provide the benefit that: the skeleton side of this low eddy-current loss reactor is wound with coil, two spring cards it are provided with at frame center, the cross section of spring card is C-shaped, one layer of flexible liner it is equipped with inside two spring cards, in spring card, card has the lamination of the three compact arranged long and narrow lamellars of row, and lamination is the most all by the fixing bonding of glass fibre.This reactor utilizes the spring card of C-shaped and flexible liner tightly to be wrapped by lamination, add the bonding tightness of lamination, improve the concordance of reactor, have employed the narrower lamination of three row to be bonded together by the good glass fibre of insulating properties is fixing, reduce the width of this core of reactor, reduce eddy-current loss.

Detailed description of the invention
Describe the preferred implementation of a kind of low eddy-current loss reactor of this utility model below in conjunction with the accompanying drawings in detail.
Fig. 1 and Fig. 2 shows the detailed description of the invention of a kind of low eddy-current loss reactor of this utility model: this low eddy-current loss reactor includes that center is provided with the skeleton 1 of through hole, as shown in Figure 1, skeleton 1 side is wound with coil 2, and coil 2 two stretches out lead-out wire 5, skeleton 1 center is provided with two the most identical spring cards of shape and size 3.
As shown in Figure 2, the cross section of spring card 3 is C-shaped, and two spring card 3 indentation, there be oppositely arranged, two spring cards 3 are internal is equipped with one layer of flexible liner 6, in spring card 3, card has the lamination 4 of the three compact arranged long and narrow lamellars of row, lamination 4 is the most all by the fixing bonding of glass fibre, and lamination 4 is less than the stalloy manufacture of 0.2 by thickness.
In conjunction with Fig. 1 and Fig. 2, skeleton 1 is manufactured by PVC plastic, and low cost is firm in structure, and good insulation preformance.Coil 2 is manufactured by copper cash, conducts electricity very well, and this reactor can be made to have higher inductance.
Spring card 3 is by the spring steel manufacture that the trade mark is 3Cr13Mo, elastic force is powerful, the lamination 4 at center can be wrapped tightly, flexible liner 6 is by high temperature resistant glue bonding fixing with spring card 3, being guaranteed in after this reactor works a period of time and produce heat, flexible liner 6 will not come off with spring card 3.Flexible liner 6 is manufactured by insulating resin, good insulation preformance, and flexible liner 6 and lamination 4 interference fit.
This reactor utilizes the spring card 3 of C-shaped and flexible liner 6 tightly to be wrapped by lamination 4, add the bonding tightness of lamination 4, improve the concordance of reactor, have employed the narrower lamination of three row 4 to be bonded together by the good glass fibre of insulating properties is fixing, reduce the width of this core of reactor, make eddy current in the loop of thin-and-long, by less cross section, to increase the resistance on eddy current path, reduce eddy-current loss.
Above is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model; can also make some deformation and improvement, these broadly fall into protection domain of the present utility model.
