Description
Technical field
The utility model relates to field transformer, is specifically related to a kind of bobbin seal structure.
Background technology
Along with the development of power technology, transformer is more and more extensive in the application of industrial circle.Transformer is primarily of compositions such as primary winding, auxiliary winding and iron cores.Oil immersed type voltage device is the most common, usually the entirety of Transformer Winding and iron core composition is immersed in industrial heavy oil, can dispel the heat on the one hand, can insulate simultaneously, primary winding is introduced from input, and auxiliary winding is drawn from output, the shell splendid attire industry heavy oil of transformer, therefore must guarantee in the unlikely infiltration oil tank of transformer such as outside atmosphere, rainwater, do not make the oil in fuel tank be leaked to outside simultaneously.Prior art many employings sealing gasket simple seal, and its bolt clipping forcee is often inadequate, fastening force is too large then easily to be damaged sleeve pipe and to be fixed part, therefore easily causes sealing effectiveness bad, and the securing members such as bolt make complex structure.
Utility model content
For solving the problem of prior art middle sleeve hermetically-sealed construction poor sealing, the utility model provides a kind of good seal, structure simple bobbin seal structure.
A kind of bobbin seal structure, comprise the sleeve pipe and transformer case that connect and arrange, described sleeve pipe comprises bobbin seal ring, casing string and sleeve pipe umbrella, described sleeve pipe pack draws together the umbrella curved surface and plane that are oppositely arranged, described casing string connects described sleeve pipe umbrella center, described bobbin seal is located on described sleeve pipe umbrella planar side, and described transformer case comprises transformer sealing ring, and described bobbin seal ring coordinates with described transformer sealing ring.According to a preferred embodiment of the present utility model, the quantity of described bobbin seal ring and described transformer sealing ring is multiple.
According to a preferred embodiment of the present utility model, described sleeve pipe also comprises sleeve pipe buffering ring, and the quantity of described bobbin seal ring is multiple, and multiple described bobbin seal ring interval arranged side by side is arranged, and described sleeve pipe buffering ring is located at the gap of bobbin seal ring described in every two.
According to a preferred embodiment of the present utility model, described casing string comprises casing string body and casing string screw thread, and described casing string screw thread is located at described casing string body surface, and described transformer case also comprises screw, and described casing string coordinates with described screw.
According to a preferred embodiment of the present utility model, described transformer case also comprises transformer buffering ring, described transformer buffering ring is located at the gap of transformer sealing ring described in every two, and described transformer buffering ring and described sleeve pipe buffering ring are sponge sleeve pipe buffering ring or gum sleeve buffering ring.
The sleeve pipe of prior art adopts sealing gasket sealing, and the fastening force of bolt is often inadequate, fastening force is excessive then easily damages the fastened part of sleeve pipe, divide at sleeve pipe and transformer shell contact position after improvement and described bobbin seal ring and described transformer sealing ring are set, both with the use of, again described sleeve pipe buffering ring is set at described bobbin seal interannular, sleeve pipe buffering ring described in described transformer buffering ring is set between described transformer sealing ring and described transformer buffering ring can play cushioning effect, can seal again, make good seal.On casing string, set up described casing string screw thread simultaneously, transformer shell arranges described screw, both coordinate, and eliminate bolt connecting mechanism, make structure simple.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing described below is only embodiments more of the present utility model, for ability those of ordinary skill, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the cutaway view of the bobbin seal structure that the utility model provides.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, carry out clear, complete description to the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.
Referring to Fig. 1, is the cutaway view of the bobbin seal structure that the utility model provides.Described bobbin seal structure 1 comprises sleeve pipe 11 and transformer case 13.Described sleeve pipe 11 connects described transformer case 13.
Described sleeve pipe 11 comprises multiple sleeve pipe umbrella 111, casing string 113, bobbin seal ring 115, sleeve pipe buffering ring 117 and wiring post holes 119.Described casing string 113 is hollow circular cylinder, its central through hole is described wiring post holes 119, multiple described sleeve pipe umbrella 111 is hollow umbrella-shaped structure, its one end is plane, its hollow space is connected with described casing string 113, and interval is arranged in the same way, described bobbin seal ring 115 is annular thin wall part, its internal diameter is greater than the external diameter of described casing string 113, the quantity of described bobbin seal ring 115 is multiple, multiple described bobbin seal ring 115 is located at described sleeve pipe umbrella 111 planar side, and interval is arranged side by side, described sleeve pipe buffering ring 117 is located at bobbin seal ring 115 gap described in every two.Described casing string 113 comprises casing string body 1131 and casing string screw thread 1133.Described casing string screw thread 1133 is located at described casing string body 1131 surface.
Described transformer case 13 comprises transformer case body 131, screw 133, multiple transformer sealing ring 135 and multiple transformer buffering ring 137.Described screw 133 is located at described transformer case body 131 surface, multiple described transformer sealing ring 135 is all annular thin wall part, described transformer case body 131 is evenly located at multiple described transformer sealing ring 135 interval, and multiple described transformer buffering ring 137 is located at transformer sealing ring 135 gap described in every two respectively.
