Abstract
The utility model provides an upper portion fixing device of a body of an oil-immersed transformer. The upper portion fixing device comprises upper portion positioning nails, a positioning piece, an insulating plate, an upper portion positioning piece base and a cover plate. The upper portion positioning nails are fixed on an upper beam of the body, the upper portion positioning piece base is fixed on a cover of an oil tank, and the upper portion positioning nails are fixedly connected with the upper portion positioning piece base through the positioning piece; open pores are formed in the upper portion positioning piece base, and the pore diameter of each open pore is larger than the diameter of each upper portion positioning nail; the insulating plate is sleeved on the upper portion positioning nails. According to the structure of the upper portion fixing device, the problem that the body of the transformer is difficult to fix due to the fact that deviation is generated in manufacturing and assembling processes of the body of the transformer and the oil tank is solved; reliable insulation and sealing are carried out on the joint of the body of the transformer and the oil tank, so the problem of multipoint earthing of iron cores, clamps and the like due to contact, on the joint, of the oil tank and the body of the transformer is avoided; stability of the body of the transformer and the like in the transportation process of the transformer is achieved.
Description
Technical field
The utility model belongs to a kind of transformer manufacture technology, and a kind of oil-filled transformer device body fixture is provided.
Background technology
The device body of transformer and fuel tank are transformer two big parts, between the two must secure fixation and insulation, otherwise can cause multipoint earthing and the carrier body offset problem of iron core, folder etc., so must fix and insulation processing between device body and the fuel tank.Traditional top location structure dock with the upper beam upper flange by the fuel tank cap lower flange, and since device body and fuel tank separately manufacturing tolerance cause easily assemble difficult, complex structure and unreliable.
The utility model content
It is more rational that the purpose of this utility model provides a kind of design, oil-filled transformer device body fixture practical reliable, easy for installation.
For reaching above purpose, the technical scheme that the utility model adopts is:
A kind of oil-filled transformer device body fixture comprises top locating pin, keeper, insulation board, top keeper seat, and cover plate; Described top locating pin is fixed on device beam on one's body, and described top keeper seat is fixed on the fuel tank case lid, and described top locating pin is fixedlyed connected with top keeper seat by keeper; Described top keeper seat offers perforate, and the aperture of described perforate is greater than the diameter of top locating pin; Described insulation board is set on the locating pin of described top.
As preferred embodiment of the present utility model, described keeper is fixedlyed connected by screw bolt and nut with top keeper seat.
As preferred embodiment of the present utility model, described cover plate is fixedlyed connected with top keeper seat with securing member by seal.
As preferred embodiment of the present utility model, described top keeper seat comprises fixedly connected flange and pair of sidewalls, described flange, pair of sidewalls, and cover plate formation hollow structure, described keeper are positioned at hollow structure inside and fix by screw bolt and nut and flange.
As preferred embodiment of the present utility model, described top keeper seat offers perforate and is arranged on the flange.
As preferred embodiment of the present utility model, in the middle of described keeper is clamped in the top locating pin.
Compared with prior art, the utility model device has the following advantages at least: for cooperating being connected of external fuel tank and device body, the utility model is beam welding top locating pin on one's body device, at fuel tank case lid welding top keeper seat, the keeper seat leaves one than the big perforate of top locating pin diameter, the deviation that above-mentioned size energy absorber body and fuel tank produce in manufacturing and assembling process, guarantee that the top locating pin can stretch into this perforate and certain interval is arranged, assembling and positioning part between keeper seat and top locating pin.Make the top locating pin enter top keeper seat and not only insulate but also fastening, solved because the difficulty of docking of the oil tank of transformer that the deviation that transformer body and fuel tank two big parts produce in manufacturing and assembling process is brought and device body.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. put the beams in place; 2. insulation board; 3. top locating pin; 4. keeper; 5. fuel tank case lid; 7. top keeper seat; 8. cover plate.
Embodiment
Below in conjunction with accompanying drawing the utility model device is described further:
