Abstract
The utility model provides a transformer outgoing line bushing structure. The transformer outgoing line bushing structure comprises a ceramic bushing, a conductive rod, an outgoing line fixing component and room temperature solidified silicone rubber wrapping layers, wherein the conductive rod is fixed to the center of the top end of the ceramic bushing through the outgoing line fixing component, the lower end of the conductive rod stretches into the upper end of the ceramic bushing, and the outer surface of the ceramic bushing and the outer surface of the outgoing line fixing component are evenly covered by the room temperature solidified silicone rubber wrapping layers respectively. The transformer outgoing line bushing structure can ensure that an outgoing line bushing cannot be wetted easily even in the severely dirty and high humidity operation environments, the surface flashover phenomenon cannot happen, metal tips can be effectively prevented from discharging, the electric field distribution of the ceramic bushing is improved, and the transformer outgoing line bushing structure is conducive to long-term stable operation of transformer equipment.
Description
Technical field
The utility model relates to transformer technology field, refers in particular to a kind of transformer outlet casing tube structure.
Background technology
Transformer outlet casing tube is the inner high and low pressure of transformer to be guided to the insulating sleeve of mailbox outside, and outlet casing tube is not only as lead-in wire insulation against ground, but also the effect of undertaking anchor leg.Therefore, transformer outlet casing tube must possess and have enough dielectric strengths and mechanical strength.For distribution transformer, go deep into load center and often cause its running environment more complicated, generally all will be at heavy pollution, under the environment of high humility, move, this is for the interior insulation of outlet casing tube, external insulation performance has all proposed certain requirement, although low-voltage-grade transformer outlet casing tube generally can not run into pollution flashover problem, if but the outlet casing tube surface under middle filthy condition seriously makes moist, this phenomenon still likely occurs, and for ceramic outlet casing tube, its structure can not stop the erosion of moisture in air completely, transformer for a long time under bad weather operation can have influence on its inner insulation property.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of porcelain bushing surface of avoiding that flashover occurs, and can suppress the invasion of moisture in air simultaneously, guarantees the transformer outlet casing tube structure of the normal operation of transformer.
For achieving the above object, technical scheme provided by the utility model is: a kind of transformer outlet casing tube structure, include porcelain bushing, conducting rod and outlet fixed part, it also includes room curing silicon rubber integument, wherein, described conducting rod is fixed on center, porcelain bushing top by outlet fixed part, and to extend into described porcelain bushing upper end inner in conducting rod lower end, and described porcelain bushing and outlet fixed part outer surface all uniform fold have room curing silicon rubber integument.
The utility model is after having adopted such scheme, its great advantage be described porcelain bushing and outlet fixed part outer surface all be coated with room curing silicon rubber, even and that the hydrophobicity performance that this room curing silicon rubber has guarantees that sleeve pipe is also difficult under the running environment of heavy pollution, high humility is wetted, thereby can there is not dielectric surface flashover phenomenon; Secondly this room curing silicon rubber can effectively prevent metal tip generation electric discharge phenomena, improves the Electric Field Distribution of porcelain bushing, contributes to the long-term stability operation of transformer equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of outlet fixed part of the present utility model.
In figure: 1-porcelain bushing, 2-conducting rod, 3-outlet fixed part, 4-room curing silicon rubber integument.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
Referring to accompanying drawing 1 to shown in accompanying drawing 2, a kind of transformer outlet casing tube structure described in the present embodiment, include porcelain bushing 1, conducting rod 2, outlet fixed part 3 and room curing silicon rubber integument 4, before described porcelain bushing 1 is installed, this porcelain bushing 1 and described outlet fixed part 3 outer surfaces are all evenly scribbled to described room curing silicon rubber integument 4, until this room curing silicon rubber integument 4, solidify completely and utilize after absolute ethyl alcohol wiping, described conducting rod 2 is fixed on described porcelain bushing 1 center, top by outlet fixed part 3, and it is inner that these conducting rod 2 lower ends extend into described porcelain bushing 1 upper end.Because described porcelain bushing 1 has room curing silicon rubber integument 4 with outlet fixed part 3 outer surface uniform folds, and this room curing silicon rubber integument 4 can effectively prevent that airborne moisture to the erosion of transformer outlet casing tube and outlet casing tube surface, electric discharge phenomena occurring, thus the long-term stability operation of assurance transformer equipment.
The examples of implementation of the above are only the preferred embodiment of the utility model, not with this, limit practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection range of the present utility model.
