Abstract

The utility model relates to electrical engineering and is intended for fixing and fixing the expansion tank of the oil transformer on the surface of the cover installed on the body of the transformer tank. a cover mounted on the transformer tank body, a split clamp, which is fixed on the transformer expansion tank by means of a threaded connection, while the split clamp is connected by means of a hinge and a retainer with a support bracket, where the retainer consists of two shaped pipes - an outer and an inner shaped pipes, on one of the faces of the support bracket, a profile pipe is fixed, into which the inner profile pipe of the retainer is inserted with the ability to move up or down, holes are made in the outer profile pipe and the inner profile pipe for installation of fasteners in them, excluding the possibility of the inner profile pipe of the retainer to move in the outer profile pipe of the retainer. The achieved technical result is to simplify the possibility of adjusting the height at which the expansion tank of the transformer is installed relative to the cover installed on the body of the transformer tank. The technical result is achieved due to the fact that the fastener contains a retainer and a hinge, while the retainer contains two profile pipes of rectangular or square cross-section, one of which is inserted into the other, while at least one threaded hole is made in the outer profile pipe, designed to install a fastener in it to ensure fixation the expansion tank of the transformer to the required height. 5 ill.

Description

Technical field to which the utility model belongs

The claimed technical solution relates to electrical engineering and is intended for fixing and fixing the expansion tank of the oil transformer on the surface of the cover installed on the body of the transformer tank.

LEVEL OF TECHNOLOGY

From the prior art, a fastening for the expansion tank of a transformer is known (website https://beltp.tiu.ru/p300146987-rasshiritelnyj-bak-transformatora.html), which is a support bracket made of a bent metal strip with fastening holes. The bracket is welded on both sides to the side surface of the transformer expansion tank, the lower part of the bracket is attached to the cover mounted on the transformer tank body using fasteners.

The disadvantage of the device known from the prior art is that it does not have the ability to adjust the height at which the expansion tank of the transformer will be installed. The disadvantages can also be attributed to the fact that the mounting holes for each manufacturer of transformers are made at different distances, in connection with which it is necessary to draw up questionnaires for certain sizes.

The device described above, in terms of its essential features, is the closest analogue to the claimed utility model and is selected as a prototype.

Disclosure of the essence of the utility model

The device includes the following parts and structural elements: a support bracket, which is a bent metal strip with mounting holes, a split clamp containing at least one threaded connection, for example, a connection using a bolt, nut and washer, a hinge, and a retainer, which is two shaped pipes - outer and inner shaped tubes of rectangular or square cross-section, one of which is inserted into the other, while at least one threaded hole and at least one fastener, for example, a bolt or rivet, are made in the outer profile pipe. The split clamp is connected on one side to the support bracket by means of a hinge, and on the other side by means of a retainer.

The technical result of the claimed utility model is the ability to adjust the height at which the expansion tank of the transformer is installed relative to the cover installed on the body of the transformer tank, as well as the ability to move the mount in a horizontal plane.

The technical result is achieved due to the fact that the fastening includes a retainer and a hinge, while the retainer contains two shaped pipes of rectangular or square cross-section, one of which is inserted into the other, while at least one threaded hole is made in the outer profile pipe, intended for installation in it fasteners to secure the expansion tank of the transformer to the required height. The movement of the mount in the horizontal plane is carried out by means of a split clamp with a threaded connection.

Brief Description of Drawings

The essence of the claimed technical solution is illustrated by drawings (Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5), which shows the device.

List of items on the drawings:

1 - support bracket;

2 - mounting holes;

3 - split clamp;

4 - threaded connection;

5 - hinge;

6 - retainer;

7 - expansion tank of the transformer.

FIG. 1 shows a general view of the mount for the expansion tank of the transformer. The arrows in FIG. 1, Fig. 4 and FIG. 5 indicates the possibility of adjusting the height due to the retainer 6, on which the expansion tank of the transformer will be installed relative to the cover installed on the body of the transformer tank.

FIG. 2 shows a view A, which shows two positions of the latch 6 as an example.

FIG. 3 shows a bottom view of the mount (view B).

FIG. 4 shows the mount in axonometric projection.

FIG. 5 shows two fasteners assembled with the expansion tank of the transformer 7 in axonometric projection.

Implementation of the utility model

The device works as follows.

The split clamp 3 is put on the expansion tank of the transformer 7, the support bracket 1 is fixed to the cover installed on the body of the transformer tank (not shown in the drawing) using the fixing holes 2. The split clamp 3 is tightly fixed on the expansion tank of the transformer 7 using the threaded connection 4. The fastener is installed in a hole made in the outer profile pipe of the retainer 6 and clamps the inner profile pipe of the retainer 6. If it is necessary to adjust the fastening height, the fastener is dismantled from the hole made in the outer profile pipe of the retainer 6, after which the inner profile pipe of the retainer 6 is moved up or down to the required height, and then the fastener is installed in the hole made in the outer profile pipe of the retainer 6, as shown in FIG. 2. If it is necessary to move the fastener in the horizontal plane, it is necessary to dismantle the threaded connection 4, thereby loosening the tight fit of the split clamp 3 to the expansion tank of the transformer 7. Hinge 5 provides a rotational movement of the split clamp 3 around the axis of the hinge 5 and relative to the support bracket 1, which allows adjust the height at which the transformer expansion tank 7 is installed relative to the cover installed on the transformer tank body.

Claims (1)

A mount for the transformer expansion tank, containing a support bracket, which is a bent metal strip with fastening holes for fixing it on a cover installed on the transformer tank body, characterized in that the mount contains a split clamp, which is fixed on the transformer expansion tank by means of a threaded connection, at the same time, the split clamp is connected by means of a hinge and a retainer with a support bracket, where the retainer consists of two profile pipes - an outer and an internal profile pipes, a profile pipe is fixed on one of the edges of the support bracket, into which the inner profile pipe is inserted with the ability to move up or down of the retainer, holes are made in the outer profile pipe and the inner profile pipe for installing a fastener in them, excluding the possibility of the inner profile pipe of the retainer moving in the outer profile pipe of the retainer.
