Abstract
The utility model relates to an oil conservator of the oil-immersed transformer, in particular to a fully-sealed oil conservator. The utility model can fundamentally eliminate the leakage phenomena because of aging and chapped rubber and an end cover that is incorrectly arranged to improve the stability of the transformer. The fully-sealed oil conservator comprises an oil conservator body, an end cover with oil scales and an end cover; an oil inlet plunger base, an oil-discharging plunger base and a tube connected with the transformer are arranged on the oil conservator body, and stands for supporting the oil conservator body; the conservator body, the end cover with oil scales and the end cover are welded into integration. The utility model has the advantages of simple structure, convenient disassembly and assembly, and low cost.
Description
Technical field
The utility model relates to a kind of oil tank for oil immersion type transformer oil conservator, particularly a kind of corrugated tank oil conservator.
Background technology
At present, known oil tank of transformer oil conservator is a kind of open architecture, comprises the oil ga(u)ge seat, bolt and the seal that weld on flanged (FLGD) oil conservator body, flanged (FLGD) end cap and the end cap.The oil conservator body is installed on the oil immersed type fuel tank, mainly is that form by bolted and rubber seal is connected with end cap and fastening, and is oil-proof to guarantee oil conservator, will guarantee that simultaneously the oil level of transformer oil is in certain height.Raise because of temperature during the transformer operation, fuel tank expands, and oil level descends, and the oil subsidy in the oil conservator is charged in the transformer, and to guarantee that transformer can in time replenish enough oil, transformer could normal operation like this.And the oil conservator of said structure exists following weak point: 1, because the oily temperature alternate that works long hours easily makes the caulking gum season cracking, cause the seepage phenomenon, cause Accident of Transformer, jeopardize safe operation; 2, manufacturing and mounting process are complicated.
Summary of the invention
Technical problem to be solved in the utility model is the shortcoming at prior art, provides a kind of and can fundamentally get rid of because of ageing of rubber, cracking and the improper seepage phenomenon that causes of end cap installation, to improve the hermetically sealed oil conservator of transformer stability.
The technical scheme that solution the utility model technical problem is adopted is this hermetically sealed oil conservator, the end cap, the end cap that comprise oil conservator body, band oil ga(u)ge, the oil-feed obturating plug is arranged on the oil conservator body, the obturating plug of draining the oil and the pipe that links to each other with transformer, be used to support the supporting leg of oil conservator body, the end cap and the end cap of oil conservator body, band oil ga(u)ge are welded in one.
The utility model can effectively improve transformer safe operation reliability, increases work efficiency.
The utility model is simple in structure, easy accessibility, and low cost of manufacture has effectively been saved production cost.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the left view of Fig. 1
Among the figure: the end cap 2-of the 1-band oil ga(u)ge obturating plug 3-dehydrating breather valve seat 4-oil-feed obturating plug 5-oil conservator body 6-pipe 7-supporting leg 8-end cap of draining the oil
Embodiment
The utility model comprises oil conservator body 5, the end cap 1 of band oil ga(u)ge seat, and end cap 8, the oil-feed obturating plug 4 of electric welding on oil conservator body 5, the pipe 6 of draining the oil obturating plug 2 and linking to each other with transformer, electric welding is used to support the supporting leg 7 of oil conservator body 5 on oil conservator body 5.The end cap 1 of band oil ga(u)ge seat and end cap 8 are smoothed the surface by the punch forming of particular manufacturing craft cold shears again, and end direct with gas welding then and oil conservator body 5 is welded in one, and fluid is sealed.There are dehydrating breather valve seat 3, oil-feed obturating plug 4, pipe 6 to hold together with 5 electric welding of oil conservator body.Oil in the utility model is by managing in the 6 inflow transformer fuel tanks, and pipe 6 is a S bend pipe seat, and S bend pipe seat play supporting role to oil conservator body 5 except playing pipeline simultaneously.
After the process leakage check technology is determined the utility model ne-leakage phenomenon, degreasing and rust removal, japanning processing are carried out in surface of the present utility model and inside, promptly finish manufacturing process of the present utility model.Then, the utility model is placed on the oil tank of transformer by supporting leg 7 and S bend pipe seat, just can uses.
Claims (2)
1, a kind of hermetically sealed oil conservator, the end cap (1), the end cap (8) that comprise oil conservator body (5), band oil ga(u)ge, the pipe (6) that oil-feed obturating plug (4), the obturating plug of draining the oil (2) is arranged on the oil conservator body (5) and link to each other with transformer, be used to support the supporting leg (7) of oil conservator body (5), it is characterized in that the end cap (1) and the end cap (8) of oil conservator body (5), band oil ga(u)ge is welded in one.
