Abstract
The utility model discloses a transformer long in service life. The transformer long in service life comprises a coil rack, a magnetic core and an insulating pad, wherein a coil is wound around the coil rack, the magnetic core is arranged in a central through hole of the coil rack, the magnetic core is wrapped in the insulating pad, and the insulating pad is fixed into the through hole of the coil rack and comprises an insulating pad body, a ventilation piece arranged on the insulating pad body and a clamping piece arranged on the insulating pad body and connected to the coil rack in a clamped mode. According to the transformer long in service life, the insulating pad which enables ventilation to be achieved conveniently is arranged, and the situation that the insulating pad is aged and the service life is shortened due to the fact that all heat is sealed in the insulating pad is avoided.
Description
Technical field
An electric equipment, particularly a kind of transformer.
Background technology
According to the transformer of prior art, mainly there is such form: primary coil and secondary coil are sequentially wrapped on single coil frame, and core is attached to bobbin by the through hole of bobbin.For fear of electric leakage or other accidents, conventionally can between magnetic core and bobbin, insulation cushion be set, but magnetic core can generate heat at work, impels the aging of insulation cushion, reduce the useful life of transformer, prior art is unresolved such problem also.
Utility model content
For solving the deficiencies in the prior art, the insulation cushion that provides a kind of convenience ventilative is provided the purpose of this utility model, avoids heat to be all enclosed in insulation cushion, causes insulation cushion aging, reduces useful life.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
The transformer of long service life, comprising: the bobbin of winding around, be placed in the magnetic core in bobbin central through hole, and parcel magnetic core is also fixed on the insulation cushion in bobbin through hole; Insulation cushion forms to be had: insulation cushion body, be placed in the air-permeable member on insulation cushion body, and be located at insulation cushion body and be connected in the shackle member of bobbin.
The transformer of aforesaid long service life, air-permeable member is the first air-vent.
The transformer of aforesaid long service life, shackle member is clamping projection.
The transformer of aforesaid long service life, bobbin is provided with the limited impression corresponding to clamping projection.
The transformer of aforesaid long service life, bobbin forms to be had: bobbin body, be placed in the coil standing groove of bobbin periphery, be placed in the ventilative groove in bobbin through hole, be located at the second air-vent on bobbin body.
The transformer of aforesaid long service life, is formed with ventilative gap between ventilative groove and insulation cushion.
The transformer of aforesaid long service life, insulation cushion is rubber blanket.
Usefulness of the present utility model is: the utility model provides a kind of convenience ventilative insulation cushion, avoids heat to be all enclosed in insulation cushion, causes insulation cushion aging, reduces useful life.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of preferred embodiment of the present utility model;
The implication of Reference numeral in figure:
1 bobbin, 101 bobbin bodies, 102 limited impressions, 103 coil standing grooves, 104 second air-vents, 105 ventilative grooves, 2 magnetic cores, 3 insulation cushions, 301 insulation cushion bodies, 302 first air-vents, 303 clamping projections, 4 ventilative gaps.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
The transformer of long service life, comprising: the bobbin 1 of winding around, be placed in the magnetic core 2 in bobbin 1 central through hole, and parcel magnetic core 2 is also fixed on the insulation cushion 3 in bobbin 1 through hole; Insulation cushion 3 forms to be had: insulation cushion body 301, be placed in the air-permeable member on insulation cushion body 301, and be located at insulation cushion body 301 and be connected in the shackle member of bobbin 1.As a kind of preferred, insulation cushion 3 selects cost low, and has the rubber blanket of certain deformability.
As a kind of preferably, for the heat that facilitates magnetic core 2 to produce sheds not can aging insulation cushion 3, air-permeable member is that the first air-vent 302, the first air-vents 302 are a plurality of.
In order to facilitate fixed insulation pad 3, shackle member is clamping projection 303303; Meanwhile, bobbin 1 is provided with the limited impression 102 corresponding to clamping projection 303.
Bobbin 1 forms to be had: bobbin body 101, be placed in the coil standing groove 103 of bobbin 1 periphery, and be placed in the ventilative groove 105 in bobbin 1 through hole, be located at the second air-vent 104 on bobbin body 101; Between ventilative groove 105 and insulation cushion 3, be formed with ventilative gap 4.Prevent coil winding, bobbin 1 is provided with the standing groove that holds coil; In order allowing, from the first air-vent 302 heat out, to give out smoothly transformer, to be also provided with the second air-vent 104 on bobbin body 101, as a kind of preferred, the second air-vent 104 is located between two coil standing grooves 103.The hot cold air that is arranged so that in ventilative gap 4 has the space of exchange, smoothly dissipation of heat is gone out.
The utility model provides the ventilative insulation cushion of a kind of convenience 3, avoids heat to be all enclosed in insulation cushion 3, causes insulation cushion 3 aging, reduces useful life.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection range of the present utility model.
