Abstract
The utility model discloses a heat dissipating structure of a magnetic core of a power transformer. The heat dissipating structure comprises the magnetic core, and is characterized in that an adhesive agent layer is arranged between binding surfaces of the magnetic core. The heat dissipating structure of the magnetic core of the power transformer, which is disclosed by the utility model, has the advantages that through fixing the magnetic core by using black glue instead of a fixing insulated rubber tape, the fixing insulated rubber tape closely wrapped outside the magnetic core can be removed and the magnetic core can be exposed, so that a heat dissipating surface of the magnetic core is increased and the heat dissipating performance of the magnetic core is greatly improved; under the same environment, the temperature of the magnetic core can be reduced by 3 DEG C to 6 DEG C than the temperature of a magnetic core with an original structure; and the binding surfaces of the magnetic core are fixed through dotted glue, so that the heat dissipating structure has higher stability.
Description
Technical field
The utility model relates to a kind of power transformer, belongs to electrical equipment technical field.
Background technology
In order to reduce the production cost of power transformer, the design to power transformer at present develops to the small size direction gradually.Because volume is little, its space utilization more saturated makes transformer when work, because the heating of its inner copper cash and magnetic core, thereby causes the main transformer temperature can be high more a lot of than the product of conventional volume.In order to solve the heat dissipation problem of transformer, the method for taking in the prior art mainly is to increase small-sized fan at the main transformer periphery, makes the main transformer cooling, and has ignored the heat radiation to the magnetic core body.For fixed magnetic core, magnetic core is outer tightly to be wrapped up by insulating tape, makes that the magnetic core radiating effect is very poor.
The utility model content
The utility model technical problem to be solved provides a kind of power transformer magnetic core radiator structure, the heat dissipation problem of magnetic core when solving power transformer work.
For solving the problems of the technologies described above, the utility model provides a kind of power transformer magnetic core radiator structure, comprises magnetic core, it is characterized in that, is provided with an adhesion agent layer between the binding face of said magnetic core.
Said adhesion agent layer is the black glue of electronics.
Said adhesion agent layer is covered with the binding face of whole said magnetic core.
Be distributed with several bounding points on the binding face of said magnetic core, said adhesion agent layer is arranged at said bounding point place.
The beneficial effect that the utility model reached:
The power transformer magnetic core radiator structure of the utility model; Be to change into by the fixed insulation adhesive tape through fixed form using black glue to fix, tightly be wrapped in the outer fixed insulation adhesive tape of magnetic core, magnetic core is exposed out thereby can remove with magnetic core; Increase the magnetic core radiating surface; The heat dispersion of magnetic core is improved greatly, and under the same environment, the magnetic core temperature can reduce by 3 ℃-6 ℃ than original structure.The magnetic core faying face is fixed through a glue, has better stability.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection range of the utility model with this.
Like Fig. 1, shown in Figure 2; Power transformer comprises magnetic core 1, copper cash winding 2; Power transformer magnetic core radiator structure is that the binding face between the magnetic core 1 is bonding through the black glue 3 of electronics, has cancelled the use insulating tape and tightly has been wrapped in magnetic core external fixation magnetic core 1, makes magnetic core 1 all expose out; Increase magnetic core 1 radiating surface, improved the heat dispersion of magnetic core 1 greatly.
The black glue of electronics also is epoxy resin electronic pastes, the black glue of single liquid, the black surely glue of group, has a good initial stage to follow intensity, has good heat-resisting, ageing-resistant function, has thixotropy, is not easy to produce to hang down and flows.Can establish several fixing points on the binding face of magnetic core, it is bonding with magnetic core to be coated with the black glue 3 of electronics in fixed point, or it is bonding with magnetic core that the binding face of magnetic core all is coated with the black glue 3 of electronics.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and distortion, these improvement and distortion also should be regarded as the protection range of the utility model.
