Description
Technical field
The utility model relates to instrument transformer cubage compensation field in the safety guard of power industry, specifically a kind of built-in metal compensator.
Background technology
Be widely used in the built-in metal compensator in hydraulic oil immersion power equipment, its structure comprises metal bellows, bellows is arranged in the insulating oil of power equipment airtight container, communicated with air by the interface of joint, when insulating oil varies with temperature, the variable quantity compression compensation device bellows interior gas of insulating oil volume, realizes the auto-compensation effect of oil volume, carrys out pressure inside and outside equalizing reservoir.
There is following shortcoming in this bellows oil immersed type built-in metal compensator: 1. corrugated pipe connector passes container casing, joint is connected with housing by fastening double nut, fastening double nut sinks by installation requirement, therefore adds and require that thickness of shell size is comparatively large man-hour, forms waste of material; 2. joint need process internal and external threads, and its difficulty of processing is large; 3. be welded on the joint on bellows and housing out of plumb, easily cause the risk of leakage of oil.
Utility model content
The purpose of this utility model is to provide that a kind of production cost is low, difficulty of processing is low, and the built-in metal compensator of good airproof performance.
The purpose of this utility model adopts following technical scheme to realize:
A kind of built-in metal compensator, comprise bellows and joint, the upper/lower terminal of bellows is respectively equipped with upper cover, lower cover, unlike the prior art, also comprises
Connecting plate, described joint is arranged on connecting plate, and the lower end of connecting plate is connected with upper cover, and connecting plate upper surface is provided with groove, is provided with sealing ring in groove;
Described bellows is arranged in the housing of container, and joint passes outside housing, and the upper surface of connecting plate is connected with housing seal by bolt.
Also comprise
Gag lever post, described gag lever post is through joint, upper cover and connecting plate, and gag lever post and lower cover are spirally connected;
Adjusting nut, described adjusting nut is arranged on interface end;
Described gag lever post and adjusting nut are spirally connected.
The height of bellows is controlled by rotating adjusting nut.When enclosure interior oil pressure raises or reduce, bellows expands along gag lever post axial direction or shrinks, and is discharged by bellows interior gas or sucks, realizing the auto-compensation effect of enclosure interior oil pressure, ensureing the safe operation of instrument transformer.During using compensation device, remove gag lever post.
The beneficial effects of the utility model: 1. structure with bolts replaces former big nut structure, reduces the thickness of vessel shell body wall, reduces production cost; 2. joint only needs machining internal thread, reduces difficulty of processing; 3. sunk by bolt fastening with connecting plate, reduce the risk of equipment leakage oil, improve the security performance of equipment.Therefore, this built-in metal compensator production cost is low, difficulty of processing is low, and good airproof performance.
Accompanying drawing explanation
Fig. 1 is built-in metal compensator and the structural representation equipped with container casing thereof in embodiment;
Fig. 2 is partial enlarged drawing in circle in Fig. 1.
In figure, 1. bellows 2. upper cover 3. connecting plate 3-1. groove 4. adjusting nut 5. gag lever post 6. joint 7. bolt 8. sealing ring 9. housing 10. nut 11. lower cover.
Embodiment
Below in conjunction with drawings and Examples, the utility model content is further elaborated, but is not to restriction of the present utility model.
Embodiment:
With reference to Fig. 1 Fig. 2, a kind of built-in metal compensator, comprises bellows 1 and joint 6, and the upper/lower terminal of bellows 1 is respectively equipped with upper cover 2, lower cover 11, also comprises
Connecting plate 3, described joint 6 is arranged on connecting plate 3, and the lower end of connecting plate 3 is connected with upper cover 2, and connecting plate 3 upper surface is provided with groove 3-1, is provided with sealing ring 8 in groove 3-1;
Described bellows 1 is arranged in the housing 9 of container, and joint 6 passes outside housing 9, and the upper surface of connecting plate 3 is tightly connected by bolt 7 and housing 9.
Also comprise
Gag lever post 5, described gag lever post 5 is through joint 6, upper cover 2 and connecting plate 3, and gag lever post 5 and lower cover 11 are spirally connected;
Adjusting nut 4, described adjusting nut 4 is arranged on interface 6 end;
Described gag lever post 5 is spirally connected with adjusting nut 4.
Particularly, gag lever post 5 and the nut 10 be welded on lower cover 11 are fastenedly connected; Joint 6 is through the welding that maintains an equal level bottom connecting plate 3 centre bore to connecting plate 3; By four bolts 7 by connecting plate 3 and housing 9 inner wall tightening, thus it is inner bellows 1 to be fastened on housing 9.
Bellows 1 height is controlled by rotating adjusting nut 4.When housing 9 internal oil pressure raises or reduce, bellows 1 expands along gag lever post 5 axial direction or shrinks, and is discharged by bellows 1 internal gas or sucks, realizing the auto-compensation effect of housing 9 internal oil pressure.During using compensation device, remove gag lever post 5.
