Abstract

The utility model relates to a transformer tank adopting a trapezoidal rising base structure, which is a novel structure aiming at solving the technical problems that the original square rising base excessively consume the oil, the threaded connection leads to complex operation, processing work hour increasing, material waste and easy oil leakage, and the like. In the structure, the rising base wall and a cover plate are directly welded and the flange is also directly welded on the cover plate, thus forming a whole to be directly welded on the side wall of the transformer tank. The transformer tank has the following benefits: the rising base saves material on the basis of not changing the original functions, such as transformer oil, plates, sealing gasket, bolts and the like; and the transformer tank has simple operation, saves work hours, eliminates the hidden danger of oil leakage, and also reduces the manufacturing cost of the transformer.

Description

Adopt the oil tank of transformer of trapezoidal rising holder structure

Technical field:

The utility model relates to a kind of oil tank of transformer, relates in particular to a kind of oil tank of transformer that adopts trapezoidal rising holder structure.

Background technology:

Need the transformer of side outlet for a lot of high-pressure sides, because the outside line of coil is smaller with the tank wall distance, so must use one to raise from the outlet of fuel tank sidewall.This general structure of rising seat wall that raises seat is square, and outside cover plate adopts a bolt fastening structure with the seat wall that raises, and cover plate seals by sealing gasket between the seat wall with raising, and prevents leakage of oil.The shortcoming of this kind structure is: square rising seat waste transformer oil; The rising seat that adopts bolt fastening structure need be fixed a circle bolt and a sealing gasket when assembling, complicated operation adds man-hour, waste material, and there is the hidden danger of seepage oil in the sealing gasket sealing in addition.

Summary of the invention:

The utility model is in order to solve square rising seat excessive fuel consumption and the employing complicated operation that is threaded, increase machining period, waste material, technical problems such as easy oil impregnate provide a kind of oil tank of transformer that adopts trapezoidal rising holder structure, and it comprises oil box, the seat wall raises, cover plate and flange: described rising seat wall is a trapezium structure, by integral body of welding formation, should integral body directly be welded on the fuel tank between it and outside cover plate and cover plate and the outside flange again.

The beneficial effects of the utility model: the original function of the seat that raises is constant, on this basis, saves material, as transformer oil, and sheet material, sealing gasket, bolt etc.; And easy and simple to handle, save man-hour, stop the hidden danger of seepage oil.Also reduced simultaneously the manufacturing cost of transformer.

Description of drawings:

The trapezoidal rising holder structure of Fig. 1 the utility model schematic diagram

Fig. 2 is the side structure schematic diagram of Fig. 1

Fig. 3 is the plan structure schematic diagram of Fig. 1

Embodiment:

Referring to Fig. 1-Fig. 3, adopt the oil tank of transformer of trapezoidal rising holder structure, it comprises oil box 4, seat wall 1 raises, cover plate 2 and flange 3: described rising seat wall 1 is a trapezium structure, by welding formation one integral body, its integral body directly is welded on the fuel tank 4 between it and outside cover plate 2 and cover plate 2 and the outside flange 3.

During making, the trapezium structure of the seat wall 1 that raises directly welds extremely with outside cover plate 2, and outside flange 3 also directly is welded on the cover plate 2, forms the rising seat of an integral body, promptly trapezoidal rising seat; Again it directly is welded on the wall of fuel tank 4.

When assembling, sleeve pipe directly is fixed on the flange 3 enterprising luggages of cover plate 2 outsides and joins, if run into the inner lead damage in insulation, also can wrap up by three flange 3 holes, this kind structure is under the prerequisite that guarantees original seat 1 function that raises, and is simple to operate, economical with materials, stopping seepage oil, is a kind of novel rising holder structure.

Claims

1. adopt the oil tank of transformer of trapezoidal rising holder structure, it comprises oil box (4), seat wall (1) raises, cover plate (2) and flange (3), it is characterized in that: described rising seat wall (1) is trapezium structure, by integral body of welding formation, should integral body directly be welded on the fuel tank (4) again between it and outside cover plate (2) and cover plate (2) and the outside flange (3).
