Description

A special tool for removing general caps of transformer high-voltage bushings

technical field

The utility model belongs to the technical field of transformer maintenance, in particular to a special tool for removing a general cap of a high-voltage bushing of a transformer.

Background technique

Disassembly of transformer high-voltage bushing general cap is an important task in the transformer maintenance industry. It occurs frequently and has high requirements for disassembly, maintenance and installation. If the requirements are not met, it is easy to cause transformer failure and danger. At the same time, due to the relatively harsh operating environment of the transformer, the general cap of the high-voltage bushing is easily bonded to the bushing platform, making it difficult to disassemble the general cap. Use tools such as wrenches and screwdrivers. In extreme cases, it needs to be completed with the help of a crane. During the disassembly process, it is time-consuming and laborious, and it is easy to cause damage to the general cap and related gasket components.

Wherein, the top center of the bell jar is provided with an opening, and the bottom of the cylindrical ejector rod is fixed in the opening in a rotatable manner, and protrudes toward the inner cavity of the bell jar; the upper part of the ejector rod has a horizontal direction and the diameter of the through hole is slightly larger than that of the rocker, which is used to horizontally insert the rocker into the through hole;

The bottom of the bell-shaped jar extends horizontally to the outside for the same length to form a circle of rims; two openings are arranged on the outer edges of the rims along the circumference.

Preferably, the opening directions of the two openings are opposite.

Preferably, a movable spacer is detachably provided at the bottom of the push rod.

Compared with the prior art, the special tool for removing the general cap of the transformer high-voltage bushing provided by the utility model has at least the following beneficial effects:

The special tool for removing the general cap of the transformer high-voltage bushing provided by the utility model is an integral tool specially used for disassembling the general cap of the transformer high-voltage bushing. The disassembly process saves time and effort, and reduces the damage rate of the general cap and other related accessories. It can be widely used in the industry to facilitate the completion of disassembly work.

Description of drawings

Fig. 1 is a structural schematic diagram of a special tool for removing a general cap of a transformer high-voltage bushing of the present invention.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments are by no means limiting the utility model.

As shown in Figure 1, the special tool for removing the general cap of the high-voltage bushing of the transformer includes: rocker 1, ejector rod 2 and bell housing 3;

Wherein, an opening is provided at the top center of the bell jar 3, and the bottom of the cylindrical push rod 2 is fixed in the opening in a rotatable manner (such as a screw thread), and protrudes toward the inner chamber of the bell jar 3; The upper part of the ejector rod 2 is provided with a horizontal through hole, and the diameter of the through hole is slightly larger than the rocker 1, for horizontally inserting the rocker 1 into the through hole;

The bottom of the bell jar 3 extends horizontally to the outside by the same length to form a circle of rims; two openings 4 are arranged on the outer edges of the rims along the circumference.

When using the transformer high-voltage bushing general cap removal special tool of the present utility model to unload the general cap 7 from the bushing platform, first put the bell-shaped cover 3 on the top of the conductive head 5 on the top of the general cap 7, so that the conductive The head 5 corresponds to the bottom end of the ejector rod 2; then the bell housing 3 is turned so that the two openings 4 are opposite to the screw holes on the general cap 7, and a bolt is inserted downward from the top of the opening 4 into the screw holes, Thereby the bell-shaped housing 3 is fixed on the general's cap 7; the opening direction of the two openings 4 can be designed to be reversed, so that the bolt fixing effect is the most stable, so the bell-shaped housing 3 can be more firmly fixed on the general's cap 7 on.

Subsequently, the rocking bar 1 is slowly rotated by the staff, so that the lower part of the push rod 2 protrudes from the inner cavity of the bell housing 3 and gradually becomes longer until it contacts the top of the conductive head 5; as the staff continues to rotate the rocking bar 1, The lower end of the push rod 2 uses the top of the conductive head 5 as a support point for the upward movement of the bell case 3, so that the bell case 3 moves upward together with the general cap 7 fixedly connected thereto; Therefore, the general cap 7 can be disassembled from the conductive head 5.

In order to prevent the top of the push rod 2 from wearing the conductive head 5, a movable pad 8 is detachably provided at the bottom of the push rod 2.

In addition, a manual hydraulic device can also be added to this tool to play a more labor-saving role.

The special tool for removing the general cap of the transformer high-voltage bushing provided by the utility model is an integral tool specially used for disassembling the general cap of the transformer high-voltage bushing. The disassembly process saves time and effort, and reduces the damage rate of the general cap and other related accessories. It can be widely used in the industry to facilitate the completion of disassembly work.
