Abstract
A transformer flexible partial gas tube with deformation compensating function belongs to the oil immersion type transformer technology field. The existing partial gas tube is the rigid tube, the deformation of the partial gas tube caused by the welding force provides difficult to the on-site installation; when the transformer is in whole vacuum oiling, the elastic deformation of the oil tank can cause the tension crack of the welding slot of the rigid partial gas tube is thus to leak oil. The utility model includes a metal flexible tube and two metal flexible tube joints, the fixing part of one metal flexible tube joint tightly fixed and connected with a transformer lifting base and the movable part of the metal flexible tube joint is connected with one port of the metal flexible, the fixing part of the other metal flexible tube joint is tightly fixed and connected with a main gas tube and the movable part is connected with the other port of the metal flexible tube. The advantage of the utility model is that because the partial gas tube itself has an enough deformation compensating function, the deformation of the oil tank doesn't effect the partial gas tube and simple the producing and assembling process, improve the working reliability of the transformer.
Description
Affiliated technical field
The utility model belongs to the oil-filled transformer technical field, is specifically related to a kind of branch wireway structure that is used for big capacity oil-filled transformer.
Background technology
In the manufacturing and designing of big capacity oil-filled transformer, must consideration will accumulate in the gas derivation in oil in each seat that raises of transformer top, to guarantee the dielectric strength of its inner lead.People adopt the branch wireway that the inner chamber of each seat that raises is communicated with main gas tube, thereby the gas in the oil in each seat that raises is derived by main gas tube.Wireway was a rigid pipe in existing minute, and one port is connected with the seat that raises, and the another port is connected with main gas tube, thereby allowed the inner chamber of rising seat be communicated with main gas tube.There is following problem in the branch wireway of this structure: 1, because the existence of welding stress causes the distortion of branch wireway, bring difficulty for on-the-spot the installation; 2, transformer is when carrying out the overall vacuum oiling, and the fuel tank strain can cause rigidity to divide the weld seam drawing crack of wireway and leakage of oil.
The utility model content
The purpose of this utility model is to overcome the shortcoming that existing rigidity is divided wireway, and a kind of flexible wireway that divides of transformer with deformation-compensated function is provided.
The flexible wireway that divides of the utility model device comprises a metal hose and two metal hose joints, movable part is connected with a port of metal hose the standing part of one of them metal hose joint with the fastening connection of power transformer enclosure, and movable part is connected with the another port of metal hose the standing part of another metal hose joint with the fastening connection of main gas tube.
Metal hose claims metal bellows again, in the industrial transmission that has been widely used in liquid, gas.Metal hose joint also is ripe prior art, has the commercial metals hose coupling of multiple structure available, connects as useful thread bush, the multiple product such as grade of also useful flange butt joint.
The utility model has the advantages that the branch wireway self has enough deformation-compensated functions, the fuel tank distortion can not influence the branch wireway, and can simplify and make and assembly technology, improves the functional reliability of transformer.

Embodiment
Embodiment: present embodiment is used for the transformer that model is SFPSZ10-H-180000/220GY.This transformer has used 8 flexible wireways 1 that divide altogether.Each is flexible, and to divide wireway 1 be that metal hose and two screw thread socket joint type metal hose joints 2 and 3 of 12mm are formed by an internal diameter.Movable part is connected with a port of metal hose 1 standing part of metal hose joint 3 with the fastening connection of power transformer enclosure, and movable part is connected with the another port of metal hose 1 standing part of metal hose joint 2 with main gas tube 5 fastening connections.4 is raise in the seat one of 8 in transformer among the figure, and 6 is the transformer top.
Above embodiment is only for the utility model is described in further detail, and scope of the present utility model is not subjected to the limitation of illustrated embodiment.
