The utility model discloses rational in infrastructure, easy and simple to handle, can adjust the mounting height of pressure release valve, the maintenance, the transportation of the pressure release valve of being convenient for can also prevent pressure release valve malfunction.

Description

Mounting structure of transformer pressure relief valve

Technical Field

The utility model relates to a mounting structure of transformer pressure relief valve.

Background

When the transformer is used, a pressure release valve is required to be arranged on the transformer and used for releasing oil pressure in the transformer and preventing the oil pressure in the transformer from being too high and leakage or explosion from occurring. The existing pressure release valve is directly installed on a box cover of the transformer, when the pressure release valve needs to be overhauled, oil needs to be discharged from oil in an oil tank, the liquid level of the oil is prevented from being too high, the oil leaks from an installation position during maintenance, and meanwhile, when the oil level of an oil conservator of the transformer is too high, the pressure between the oil conservator and the pressure release valve is too high, and the misoperation of the pressure release valve can be caused.

Disclosure of Invention

In view of this, the utility model aims at providing a mounting structure of transformer pressure release valve, rational in infrastructure, easy and simple to handle, can adjust the mounting height of pressure release valve, the maintenance, the transportation of the pressure release valve of being convenient for can also prevent pressure release valve malfunction.

The technical scheme of the utility model is that: the utility model provides a mounting structure of transformer pressure relief valve, is provided with a plurality of mount pad including setting up flange and the butterfly valve on the transformer case lid in the butterfly valve upper end, is provided with the pressure relief valve above the mount pad.

Furthermore, the mounting base comprises a lower flange, an upper flange is arranged above the lower flange, and a connecting pipe is arranged between the lower flange and the upper flange.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses rational in infrastructure, easy and simple to handle, can adjust the mounting height of pressure release valve, the maintenance, the transportation of the pressure release valve of being convenient for can also prevent pressure release valve malfunction.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

in the figure: 10-a butterfly valve; 20-a mounting seat; 21-a lower flange; 22-an upper flange; 23-a connecting tube; 30-a pressure relief valve; 40-transformer tank cover.

Detailed Description

As shown in fig. 1, the mounting structure of the pressure relief valve of the transformer comprises a butterfly valve 10 arranged on a cover 40 of the transformer, a plurality of mounting seats 20 arranged at the upper end of the butterfly valve 10, and a pressure relief valve 30 arranged above the mounting seats 20. The butterfly valve 10 is fixed to a case cover of the transformer, the lowermost mounting seat 20 is fixed to the butterfly valve 10, and the pressure relief valve 30 is fixed to the uppermost mounting seat 20. The number of the mounting seats 20 can be selected according to actual use requirements, and when transportation is needed, the mounting seats 20 can be detached; when the pressure relief valve 30 needs to be overhauled, the butterfly valve 10 can be closed, so that oil cannot overflow, and the pressure relief valve can be directly overhauled.

In this embodiment, the mounting base 20 includes a lower flange 21, an upper flange 22 is disposed above the lower flange 21, and a connecting pipe 23 is disposed between the lower flange 21 and the upper flange 22. The lower flange 21 and the upper flange 22 are welded to the connecting pipe 23.

The specific working process is as follows: fixing the butterfly valve 10 on a flange welded on a transformer tank cover 40, fixing a plurality of mounting seats 20 on the butterfly valve 10 according to actual use requirements, and then fixing the pressure release valve 30 on the uppermost mounting seat 20; when the oil in the transformer oil conservator is high in operation, the number of the mounting seats 20 needs to be increased, so that the difference between the mounting height of the pressure relief valve 30 and the height of the liquid level of the highest oil level in the transformer oil conservator meets the closing pressure of the pressure relief valve.

Above-mentioned operation flow and software and hardware configuration only do as the preferred embodiment of the utility model discloses a not therefore restrict the patent scope of the utility model, all utilize the utility model discloses the equivalent transform of doing of description and attached drawing content, or directly or indirectly use in relevant technical field, all the same reason is included in the patent protection scope of the utility model.
