Abstract
The utility model relates to an oil-immersed transformer which prevents corrugated sheets leaking, belonging to the technical field of transformers. The oil-immersed transformer is characterized in that an oil conservator which is internally equipped with a rubber sac is arranged on an oil tank, which enables the functions of corrugated sheets to be changed into a single radiating function from the existing radiating function and the function of expansion or shrinkage to adapt to oil pressure change, thereby completely avoiding the corrugated sheets leaking because expansion or shrinkage enables welding positions to be extremely easy to be damaged, the oil conservator and the rubber sac inside the oil conservator bear the function of suiting the oil pressure change, namely, when the oil pressure in the oil tank is raised, the rubber sac in the oil conservator adsorbs oil entering the oil breather because the oil pressure is raised, when the oil pressure in the oil tank is reduced, the rubber sac in the oil conservator shrinks to press oil contained in the rubber sac into the oil tank. The utility model is simple in structure, not only can meet technical requirements of the oil-immersed transformer with corrugated sheets with the thickness of 1.2 mm, also can prolong the service life of the oil-immersed transformer which utilizes corrugated sheets, and is an updated product of the existing oil-immersed transformer.
Description
Technical field
The utility model relates to a kind of oil-filled transformer of preventing corrugated plate leakage, belongs to the transformer technology field.
Background technology
Early stage oil-filled transformer structure comprises fuel tank, has the iron core of high-voltage coil and low-voltage coil in the fuel tank, the radiating tube that communicates in welding fixing some and fuel tank around the fuel tank, the dehydrating breather that communicates successively and the conservator that connect on the fuel tank.The oil-filled transformer complex structure of this structure, the manufacturing cost height the more important thing is that radiating effect is not ideal enough.So, scientific and technical personnel improve the structure of this oil-filled transformer, adopt the corrugated plate of 1.5mm wall thickness to replace radiating tube, and can expand by the corrugated plate appropriateness when oil pressure raises adapts to, along with adopting corrugated plate to replace radiating tube, also cast out dehydrating breather and the conservator on the fuel tank.On the basis of guaranteeing properties of product and quality, for further energy-saving and cost-reducing, reduce production costs, the enterprise that has changes the corrugated plate of 1.5mm wall thickness into the 1.2mm wall thickness, and production cost has reduced, and radiating effect is also good, but the corrugated plate of this wall thickness is because less with the solder side of fuel tank, after having experienced the several times expansion and having shunk, weld has influenced product quality because of the impaired seepage phenomenon that occurs.
Summary of the invention
The purpose of this utility model provides a kind of oil-filled transformer of preventing corrugated plate leakage, solve existing oil-filled transformer because of the corrugated plate that adopts the 1.2mm wall thickness after having experienced several times and expanding and shrink, weld is because of the impaired deficiency that seepage occurs, realize both can guaranteeing radiating effect, can avoid corrugated plate weld seepage again.
The purpose of this utility model is achieved through the following technical solutions, a kind of oil-filled transformer of preventing corrugated plate leakage, comprise fuel tank, the iron core that has low pressure winding, high pressure winding in the fuel tank, the corrugated plate that communicates in welding fixing some and fuel tank around the high-low pressure binding post that fuel tank top is fixing, fuel tank is characterized in that, the conservator that connects through pipeline is set on the fuel tank, capsule is set in the conservator.
Capsule is cannula-like.
The utility model is the improvement of adopting the oil-filled transformer structure of corrugated plate to existing, by the conservator that has capsule in it is set on fuel tank, make corrugated plate by the heat radiation of bearing in the past with adapt to oil pressure and change and expand or two changing functions shrinking are single heat sinking function, thereby avoided corrugated plate to make the very easily impaired seepage of weld fully because of expanding or shrinking, the capsule of conservator and Qi Nei is then born and is adapted to the function that oil pressure changes, promptly when oil pressure in the fuel tank raises, capsule in the conservator absorbs because of oil pressure raises and enters the oil of conservator, when oil pressure in the fuel tank reduces, capsule in the conservator shrinks its oil that is full of of extruding and enters fuel tank, the utility model is simple in structure, not only can satisfy the specification requirement of the oil-filled transformer of 1.2mm wall thickness corrugated plate, also can improve the useful life of the oil-filled transformer that adopts corrugated plate, be the renewal product of existing oil-filled transformer.
Description of drawings
Fig. 1 is the utility model external structure schematic diagram;
Among the figure, 1 fuel tank, 2 corrugated plates, 3 conservators, 4 capsules, 5 pipelines.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the utility model is by fuel tank 1, corrugated plate 2, conservator 3, capsule 4, pipeline 5, the iron core that comprises the high-low pressure winding in high-low pressure binding post and the fuel tank 1 constitutes, the corrugated plate 2 that in welding fixing some and fuel tank 1, communicates around the fuel tank 1, and the wall thickness of present embodiment corrugated plate 2 is 1.2mm, conservator 3 is fixed on the fuel tank 1, conservator 3 is connected with fuel tank 1 through pipeline 5, and capsule 4 is an elastomeric material, is cannula-like, places in the conservator 3.
Claims (2)
1, a kind of oil-filled transformer of preventing corrugated plate leakage, comprise fuel tank, the iron core that has low pressure winding, high pressure winding in the fuel tank, the high-low pressure binding post that fuel tank top is fixing, the corrugated plate that in welding fixing some and fuel tank, communicates around the fuel tank, it is characterized in that, the conservator that connects through pipeline is set on the fuel tank, capsule is set in the conservator.
2, the oil-filled transformer of preventing corrugated plate leakage according to claim 1 is characterized in that, capsule is cannula-like.
