Abstract
The utility model relates to a transformer and particularly relates to an oil tank of an oil-immersed transformer. The oil tank comprises an integrally-formed tank body and a tank cover which is covered with the tank body, wherein heat radiating fins are respectively and vertically arranged on the periphery outside the tank body and are corrugated; and a rubber sealing ring is arranged between the tank body and the tank cover. According to the oil tank disclosed by the utility model, a stator and a rotor are arranged in an enclosure and the tank body and the sealing ring which are integrally formed are arranged on the oil tank, so that the whole oil tank is better in sealing property and the leakage of oil in the oil tank is effectively prevented; and in addition, the corrugated heat radiating fins are arranged on the tank body of the oil tank, so that the oil tank is low in cost and favorable in heat radiating effect.
Description
Technical field
The utility model relates to oil-filled transformer, is oil tank for oil immersion type transformer specifically.
Background technology
Transformer is one of visual plant in the power transmission and transformation system, and oil-filled transformer is a kind of of transformer, is used in the power transmission and transformation system.Yet the seepage of oil-filled transformer and heat dissipation problem are the difficult problems that the technical staff will solve.At present, the radiating tube that the fuel tank of some oil-filled transformer communicates with casing through setting on casing is to reach the purpose of heat radiation.But the transformer oil tank structure of this structure is complicated, and radiating effect is good inadequately, and cost is higher, and sealing is also good inadequately.
The utility model content
The utility model has solved above-mentioned technical problem, provides a kind of heat radiation better and good sealing performance oil tank for oil immersion type transformer.
The technical scheme that the utility model solves the problems of the technologies described above employing is that oil tank for oil immersion type transformer comprises integrated casing and the case lid that covers with this casing, all vertically is provided with fin around the said casing outside.
The utility model also has following additional technical feature:
Said fin is corrugated.
Be provided with rubber seal between said casing and the case lid.
Can know that from above technical scheme the utility model adopts integrated casing and sealing ring, make the better tightness of whole fuel tank effectively to prevent the oil seepage in the fuel tank; And the casing of the utility model is provided with undulatory fin, and its cost is low, good heat dissipation effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Specify the utility model below in conjunction with accompanying drawing 1:
This oil tank for oil immersion type transformer comprises integrated casing 1 and the case lid 2 that covers with this casing; Casing and and case lid between be provided with rubber seal 4; Case lid 2 is connected with the available bolt in case edge of casing 1 or welds; Form the total closed type Oiltank structure, make transformer oil not contact, prolong the useful life of fuel tank with surrounding air.Because transformer oil can not absorb extraneous moisture, thereby can not reduce dielectric strength; In addition because of oxygen can't get into fuel tank, thereby avoid the aging of insulating material, improved the physical life of fuel tank, also improved social benefit simultaneously.
In this execution mode, said casing all vertically is provided with fin 3 around 1 outside, and said fin is corrugated.When the oil temperature in the fuel tank changes, the expand with heat and contract with cold effect of instead oil conservator of corrugate fin, and corrugated fuel tank good looking appearance, floor space is also less.From the above, the utility model has solved the bad and poor sealing two large problems of transformer heat radiation better.
Above-mentioned execution mode only supplies to explain the usefulness of the utility model; And be not to be the restriction to the utility model; The those of ordinary skill in relevant technologies field; Under the situation that does not break away from the utility model spirit and scope, can also make various variations or modification, so all technical schemes that are equal to also should belong to the category of the utility model.
Claims (3)
1. oil tank for oil immersion type transformer is characterized in that: all vertically be provided with fin (3) around the case lid (2) that comprises integrated casing (1) and cover with this casing, said casing outside.
2. oil tank for oil immersion type transformer according to claim 1 is characterized in that: said fin (3) is corrugated.
