Abstract

The utility model discloses a paper tinsel coil for transformer, include: a circular coil cylinder, the outer coiling of circular coil cylinder has interior coil and outer winding, interior coil with the outer winding intussuseption is filled with the heat dissipation granule, two insulating layers, two the insulating layer is established respectively outer winding's both sides, be equipped with a plurality of support bars and a plurality of micropore in the insulating layer, a fire -retardant layer, establish outmost on fire -retardant layer on the outer wall of insulating layer. In this way, the utility model relates to a paper tinsel coil for transformer, the interior coil and the outer winding intussuseption of this paper tinsel coil are filled with the heat dissipation granule, have improved transformer coil's heat dispersion greatly, can effectively improve the transformer reliability and continuous operation the time long, and the structure is comparatively simple, manufacturing cost is lower.

Description

A kind of transformer paper tinsel coiling

Technical field

The utility model is related to transformer technology neighborhood, and in particular to a kind of transformer paper tinsel coiling.

Background technology

In transformer, coil is a very important part, and dry-type transformer is relative to oil-filled transformer For, it is that a kind of unshakable in one's determination and low-voltage coil is not immersed in the transformer in iknsulating liquid, is generally used for local lighting and electronic circuit, Existing transformer coil radiating effect is undesirable, and coil outer layer becomes generally around contracting strap, low intensity, the easy distending of coil is packed tightly Shape, so as to fail, as coil is the conductor of electric current, insulating properties are particularly important, and existing coil is generally all adopt exhausted Edge paper separating in layer by cable, but general insulating paper compare it is thin, creep age distance not enough, so for high pressure sets It is abnormally dangerous for standby.

Utility model content

The utility model is mainly solving the technical problems that provide a kind of transformer paper tinsel coiling.

For solving above-mentioned technical problem, the technical scheme that the utility model is adopted is：A kind of paper tinsel coiling of transformer Circle, including：

One circular coil cylinder, is wound with interior loop and exterior loop outside the circular coil cylinder, the interior loop is outer with described Filled with radiating particle in coil；

Two insulating barriers, insulating barrier described in two are respectively provided at the both sides of the exterior loop, if being provided with the Heavenly Stems and Earthly Branches in the insulating barrier Stay and some micropores；

One flame-retardant layer, the flame-retardant layer are located on the outer wall of insulating barrier described in outermost layer.

In one preferred embodiment of the utility model, the insulating barrier is resin insulating barrier.

In one preferred embodiment of the utility model, the quantity ratio of the support bar and the micropore in the insulating barrier For 1：20.

In one preferred embodiment of the utility model, the flame-retardant layer is glass fibre adhesive tape.

In one preferred embodiment of the utility model, the thickness of the flame-retardant layer is 4 ~ 6mm.

The beneficial effects of the utility model are：A kind of the utility model transformer paper tinsel coiling, the paper tinsel coiling it is interior Filled with radiating particle in coil and exterior loop, the heat dispersion of transformer coil is substantially increased, transformation can be effectively improved The reliability of device and the duration of continuous work, and structure is relatively simple, production cost is relatively low.

Description of the drawings

Fig. 1 is a kind of structural representation of transformer paper tinsel coiling.

In accompanying drawing, the mark of each part is as follows：1st, circular coil cylinder；2nd, interior loop；3rd, exterior loop；4th, insulating barrier；5th, support Bar；6th, micropore；7th, flame-retardant layer.

Specific embodiment

Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to make to protection domain of the present utility model Define.

Fig. 1 is referred to, the utility model embodiment includes：A kind of transformer paper tinsel coiling, including：

One circular coil cylinder 1, is wound with interior loop 2 and exterior loop 3, the interior loop 2 and institute outside the circular coil cylinder 1 State in exterior loop 3 filled with radiating particle；

Two insulating barriers 4, insulating barrier 4 described in two are respectively provided at the both sides of the exterior loop 3, and the insulating barrier 4 is that resin is exhausted Edge layer, the high mechanical strength of resin insulating barrier, insulation effect are notable.

Some support bars 5 and some micropores 6 are provided with the insulating barrier 4, the support bar 5 and institute in the insulating barrier 4 The quantity ratio for stating micropore 6 is 1：20, the support bar 5 is coordinated with the micropore 6, not only so that the insulating barrier 4 has well Supporting role, and substantially increase the heat dispersion of transformer coil, reliability and the company of transformer can be effectively improved The duration of continuous work.

One flame-retardant layer 7, the flame-retardant layer 7 are located on the outer wall of insulating barrier 4 described in outermost layer, and the flame-retardant layer 7 is glass Fiber adhesive tape, glass fibre adhesive tape can not only increase the mechanical strength for becoming electric coil, and play through flame treatment Fire-retardant effect, prevents from becoming electric coil aoxidizing because temperature is too high.

The thickness of the flame-retardant layer 7 is 4 ~ 6mm, and the thickness of flame-retardant layer 7 described in the present embodiment is 5mm.

Compared with prior art, a kind of transformer of the utility model paper tinsel coiling, the interior loop of the paper tinsel coiling and outer Filled with radiating particle in coil, the heat dispersion of transformer coil is substantially increased, the reliability of transformer can be effectively improved Property and continuous work duration, and structure is relatively simple, and production cost is relatively low.

Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every The equivalent structure made using the utility model specification and accompanying drawing content or equivalent flow conversion, or be directly or indirectly used in Other related technical fields, are included in scope of patent protection of the present utility model in the same manner.
