Description
Technical field
The utility model relates to a kind of transformer pipeline, belongs to field transformer.
Background technology
Oil tank of transformer is a kind of safety guard of transformer.On existing oil tank of transformer, be all provided with for by the copper pipe of load current, the outer surface of copper pipe is provided with the stay of the quartering, and stay can be strengthened compressive resistance and the non-deformability of copper pipe.In oil tank of transformer, be full of insulating oil, insulating oil applies identical pressure to the tube wall of copper pipe.Yet the support bar on copper pipe outer surface can cause copper pipe under the effect of insulating oil, tube wall unbalance stress produces deformation.Copper pipe distortion can make to produce gap between insulated tube and copper pipe and cause oil tank of transformer to leak electricity.
Summary of the invention
The problem that the utility model need to solve has been to provide a kind of transformer pipeline, avoids copper pipe because pipe deforming occurs unbalance stress.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of transformer pipeline, comprise copper pipe and the voltage equalizing ball that is arranged on copper pipe one end, on described voltage equalizing ball, cover has insulating cover, on described copper pipe, cover has insulated tube, on described insulated tube, cover has corrugated paper, described corrugated paper comprises inner paper, core paper and facial tissue, the inner surface of described inner paper is adjacent to the outer surface of described insulated tube, described core paper be around fold paper, described fold paper is provided with the uniform crest section in some intervals and trough section, described crest section is close to facial tissue inner surface, described trough section is close to inner paper outer surface.
Further, described corrugated paper at least comprises two-layer core paper from the inside to surface, and between adjacent two-layer described core paper, cover has connection paper, and the corresponding core paper crest section near described inner paper end of the core paper trough section of close described facial tissue end.
Further, described corrugated paper one end extends to voltage equalizing ball, and described insulating cover outer surface is close in one end that described corrugated paper extends on voltage equalizing ball.
Further, on described copper pipe, be at least provided with a bending section.
Further, the thickness of described insulated tube is 0.3mm-0.5mm.
Further, the thickness of described insulating cover is 0.1mm-0.3mm.
The beneficial effects of the utility model:
Corrugated paper is by being enclosed within on insulated tube, and the tube wall of realizing copper pipe is subject to identical oil pressure, effectively avoids copper pipe to deform.In on corrugated paper, paper is close to copper pipe, avoids corrugated paper to come off from copper pipe.Facial tissue on corrugated paper contacts with insulating oil, slows down the speed of insulating oil infiltration corrugated paper.Core paper be around fold paper, between the facial tissue linking together by fold paper and inner paper, must form the heat dissipation channel of axial setting, heat dissipation channel can be realized copper pipe heat radiation.
Between different core papers, be provided with connection paper, can make the pressure on outer core paper evenly be delivered on internal layer core paper, avoid core paper unbalance stress and produce local gross distortion.Meanwhile, connect paper and can also completely cut off insulating oil, slow down the speed that insulating oil is invaded profit corrugated paper.Near the corresponding core paper crest section near described inner paper end of the core paper trough section of described facial tissue end, can avoid pressure-acting on core paper on paper, to go and cause articulamentum that serious distortion occurs to connecting.Connect after paper generation gross distortion, the heat dissipation channel forming on fold paper can diminish.
Corrugated paper is adjacent to the outer surface of insulating cover, avoids insulating oil to flow into insulated tube from insulating cover.Copper pipe is provided with bending section, can stop corrugated paper to move axially along copper pipe.The thickness of the Thickness Ratio insulating cover of insulated tube is large, can increase the contact area of corrugated paper and insulating cover.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of transformer pipeline of the utility model;
Fig. 2 is the cutaway view of A-A in Fig. 1.
Embodiment
See figures.1.and.2, a kind of transformer pipeline, comprises copper pipe 1 and voltage equalizing ball 2, and voltage equalizing ball 2 is arranged on one end of copper pipe 1.On copper pipe 1, cover has insulated tube 11, and on insulated tube 11, cover has corrugated paper 3, and on voltage equalizing ball 2, cover has insulating cover 21.
Corrugated paper 3 comprises inner paper 4, core paper and facial tissue 5, and the inner surface of inner paper 4 is close to the outer surface of insulated tube 11, core paper be around fold paper, core paper comprises core paper 6 and core paper 7, core paper 6 is looped around on inner paper 4, and core paper 6 trough section 61 sidewalls are close on the outer surface of inner paper 4.Between core paper 6 and core paper 7, be provided with and connect paper 8, connect paper 8 and be enclosed within on core paper 6.The inner surface that connects paper 8 is close to the sidewall of core paper 6 crest sections 62, and the outer surface that connects paper 8 is close to the sidewall of core paper 7 trough sections 71, and crest section 62 contacts trough section 71 by connecting paper 8.Facial tissue 5 is enclosed within on core paper 7, and the sidewall of core paper 7 crest sections 72 is close to the inner surface of facial tissue 5.
In the utility model, adopt double-deck core paper structure, but in Practical manufacturing, designer can increase or reduce the number of plies of core paper according to the actual requirements.Corrugated paper 3 can be working of plastics, rubber parts, can be also paper part, can only corrugated paper 3 can play and stop insulating oil to invade profit copper pipe 1.Trough section 61 and crest section 62 are evenly arranged on core paper 6, and trough section 71 and crest section 72 are evenly arranged on core paper 7, and while facilitating core paper 6 and core paper 7 to be close to, crest section 62 energy and trough section 71 are corresponding one by one.
