Abstract

The utility model relates to a novel transformer oil box, and is characterized in that a reinforced trough is arranged on the box wall, the reinforced trough is best to be provided on the lateral box wall, the reinforced trough is best to form one body with the box wall or the lateral box wall, and the reinforced trough is best to be taken in an outer convex trough shape. Compared with the prior art, the utility model has the obvious advantages that firstly, a reinforced rib which is welded on the box wall is canceled in the utility model, the weight and the processing cost of the transformer are lowered, secondly, the reinforced structure of the box wall is rebuilt in the utility model for eliminating the rust-returning phenomenon which is caused by welding the reinforced rib, thirdly, the utility model enhances the appearance quality of products and improves the process technology.

Description

The novel transformer fuel tank

One, technical field:

The utility model relates to the fuel tank of transformer, is a kind of novel transformer fuel tank.

Two, background technology:

The Oiltank structure of present middle-size and small-size transformer is square or circular barrel type tank mostly, shown in Fig. 4,5 and 6, this kind fuel tank often is welded with the mechanical strength that a lot of reinforcements 4 guarantee fuel tank around tank wall 3, and tank wall 3 also will be thickeied, course of processing complexity influences operating efficiency, also might occur returning the rust phenomenon simultaneously, influence attractive in appearancely, increase maintenance workload.

Three, summary of the invention:

The utility model has improved the tank wall reinforcement of oil tank of transformer, has eliminated because of what welding caused and has returned the rust phenomenon.

The technical solution of the utility model is achieved in that a kind of novel transformer fuel tank, and it has strengthening groove at least on a tank wall.

Strengthening groove is preferably arranged on above-mentioned side box wall.

Above-mentioned strengthening groove preferably and tank wall or side box wall be one.

Above-mentioned strengthening groove preferably is the evagination groove shape.

The utility model advantage compared with prior art is fairly obvious:

A. the utility model has been cancelled the reinforcement that welds on tank wall, has reduced the weight and the processing cost of transformer.

B. the utility model is exerted the reinforcement that has improved tank wall, eliminates because of what the welding reinforcement caused and returns the rust phenomenon;

C. the utility model has improved the presentation quality of product, and processing technology is improved.

Four, description of drawings:

Fig. 1 is the main TV structure schematic diagram of the utility model most preferred embodiment,

Fig. 2 is the plan structure schematic diagram of Fig. 1,

Fig. 3 is the side-looking sectional structure schematic diagram of Fig. 1,

Fig. 4 is the main TV structure schematic diagram of existing oil tank of transformer,

Fig. 5 is the plan structure schematic diagram of Fig. 4,

Fig. 6 is the side-looking sectional structure schematic diagram of Fig. 4,

Among the figure: 1. tank wall, 2. strengthening groove; 3. existing tank wall, 4. strengthening groove.

Five, embodiment:

Shown in Fig. 1,2 and 3, a kind of novel transformer fuel tank, it has strengthening groove 2 at least on a tank wall 1, be preferably in strengthening groove 2 is arranged on the side box wall, and strengthening groove 2 preferably and tank wall 1 or side box wall be one, preferably form strengthening groove 2, and strengthening groove 2 preferably is the evagination groove shape, as shown in Figure 3 by punching press.

The utility model is not subjected to the restriction of above-mentioned most preferred embodiment, can determine its concrete structure according to technique scheme and actual conditions.
