Description

Universal oil filling flange device for transformer

technical field

The utility model relates to a flange, in particular to a universal oil-filling flange device for a transformer.

Background technique

The oil-immersed power transformer is the most important equipment in the substation, and the safe and stable operation of the transformer is very important to the power grid. During the process of new installation, overhaul and maintenance of transformers, oil filling operations are often required. Since there are no standard requirements for the specifications and shapes of the oil filling and draining valves of the transformer body, the specifications of the oil filling and draining valves of transformers with different voltage levels from different manufacturers are also different, resulting in transformer During the oil filling operation, it is necessary to process and manufacture the oil filling flange device on site according to the specifications of the transformer oil filling valve, which not only consumes time, manpower and material resources, reduces work efficiency, but also increases the power outage time of the transformer, which is not conducive to the safe and stable operation of the regional power grid.

In order to solve the above existing problems, people have been seeking an ideal technical solution.

Contents of the invention

The purpose of the utility model is to aim at the deficiencies of the prior art, thereby providing a universal oil-filling flange device for transformers with strong versatility, simple structure and convenient use.

In order to achieve the above object, the technical solution adopted in the utility model is:

A universal oil injection flange device for transformers, which includes a flange and an oil injection pipeline arranged in the center of the flange, the flange is provided with horizontal or vertical connection holes, and the flange is also provided with There is a U-shaped hoop, and the U-shaped hoop passes through the connection hole and is connected with the flange bolt.

Based on the above, the connection holes are strip-shaped and symmetrically arranged on both sides of the oil injection pipeline.

Compared with the prior art, the utility model has substantive features and progress. Specifically, the utility model adopts a U-shaped hoop to clamp the oil injection valve on the flange, and uses a strip-shaped connecting hole to adjust the U-shaped hoop The position is suitable for oil filling valves of different specifications, which has the advantages of strong versatility, simple structure and convenient use.

detailed description

The technical solutions of the present invention will be further described in detail through specific implementation methods below.

As shown in Figure 1, a universal oiling flange device for transformers is provided with an oiling pipe 3 at the center of the flange 1, and connecting holes 2 are arranged symmetrically on both sides of the oiling pipe 3, and the connecting holes 2 are horizontal or vertical In order to facilitate the adjustment of the position of the U-shaped hoop 4 according to the specifications of the oil injection valve, the two ends of the U-shaped hoop 4 are respectively provided with external threads to facilitate the passage of the U-shaped hoop 4 through the nut 5 connected to the flange 1.

When in use, align the oil injection valve with the oil injection pipeline 3, clamp the U-shaped hoop 4 to the oil injection valve, and adjust the position of the U-shaped hoop 4 penetrating into the connecting hole 2 according to the specifications of the oil injection valve. After the position, pass the two ends of the U-shaped hoop 4 through the connecting hole 2 respectively, and then respectively screw the nuts 5 on the ends of the U-shaped hoop 4, so that the The U-shaped hoop 4 is fixed on the flange 1 and the oil injection valve is clamped on the flange 1 .

Preferably, as shown in FIG. 1 and FIG. 2 , there are four connecting holes 2 and two U-shaped hoops 4 , which are arranged symmetrically on both sides of the oil injection pipeline 3 .

When in use, each of the U-shaped hoops 4 corresponds to two parallel and symmetrical connecting holes 2, and the two ends of the U-shaped hoops 4 respectively pass through the connecting holes 2, and then respectively connect the The nut 5 is screwed on the end of the U-shaped hoop 4 so as to fix the U-shaped hoop 4 on the flange 1 and fix the oil injection valve on the flange 1 .

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model and not limit it; although the utility model has been described in detail with reference to the preferred embodiment, those of ordinary skill in the art should understand that: still The specific implementation of the utility model can be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solution of the utility model, all of them should be included in the scope of the technical solution claimed by the utility model.
