Description

Technical Field

[0001] The utility model relates to, but is not limited to, the technical field of busbar clamps, and in particular to a busbar connection clamp suitable for an L-shaped arrangement of high-voltage busbars in a transformer substation. Background Art

[0002] Currently, in substation projects, due to geographical restrictions, busbars in some newly built or expanded substations are not arranged in a straight line. This leads to problems in the selection of hardware during the connection of two busbar sections. However, there are no special adapter clamps available, and the corner connection of the two busbar sections is usually completed by combining ordinary 0 / 90 degree clamps with aluminum plates.

[0003] Due to the large number of components required for installation, a large number of bolts are required for fixing the components. These bolts are used for two clamps and one aluminum plate. Furthermore, the contact surface between the components is reduced due to the bolts. Furthermore, the bolts create many protruding points, resulting in high radio interference. Therefore, a busbar connection clamp suitable for L-shaped high-voltage busbar arrangements in substations was designed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a busbar connecting wire clamp suitable for L-shaped arrangement of high-voltage busbars in transformer substations.

A card slot is provided on the surface of the connecting column, and an elastic card block adapted to the card slot is provided on the inner wall of the connecting groove.

[0011] As a preferred technical solution of the present invention, a rotation groove adapted to the rotation block is opened on the outer side of the wire clamp fixing plate, and the rotation block is rotatably connected to the wire clamp fixing plate through the rotation groove.

[0012] As an optimal technical solution of the present invention, the interior of the wire clamp fixing plate and the rotating block are both provided with limiting holes adapted to the limiting column. The limiting column passes through the wire clamp fixing plate through the limiting hole, and the bottom end is plugged into the wire clamp fixing plate and passes through the rotating block.

[0024] like Figure 1-3 As shown, the utility model provides a busbar connection clamp suitable for L-shaped arrangement of high-voltage busbars in substations, comprising a mounting base 1, a lead crimping tube 2 and a clamp fixing plate 3. The clamp fixing plate 3 is arranged on two adjacent sides of the mounting base 1, and the lead crimping tube 2 is arranged on one side of the clamp fixing plate 3.

[0025] The adjusting assembly 4 is arranged between the rear end of the lead crimping tube 2 and the wire clamp fixing plate 3. The adjusting assembly 4 includes a rotating block 401 and a connecting column 402. The connecting column 402 and the rotating block 401 are integrated;

[0026] The limiting member 5 is arranged between the adjustment component 4 and the wire clamp fixing plate 3. The limiting member 5 includes a limiting column 501. A limiting block 502 is arranged on the outer side of the limiting column 501.

[0027] Furthermore, in this embodiment, the mounting base plate 1 and the wire clamp fixing plate 3 are welded, and the top surfaces of the mounting base plate 1 and the wire clamp fixing plate 3 are L-shaped. The angle between the wire clamp fixing plate 3 and the mounting base plate 1 is set according to different angles before leaving the factory, and then welding is performed to obtain an integrated mounting base plate 1 and wire clamp fixing plate 3 assembly with different angles.

[0028] In this embodiment, a connecting groove 201 adapted to the connecting column 402 is provided at the rear end of the lead crimping tube 2, and the connecting column 402 is plugged into the lead crimping tube 2 through the connecting groove 201. A card slot 403 is provided on the surface of the connecting column 402, and an elastic card block adapted to the card slot 403 is provided on the inner wall of the connecting groove 201. The connecting column 402 is installed inside the rear end of the lead crimping tube 2 through the connecting groove 201, and the elastic card block cooperates with the card slot 403 to improve the firmness of the connection between the connecting column 402 and the lead crimping tube 2.

[0029] In this embodiment, a rotating groove 101 adapted to the rotating block 401 is opened on the outer side of the wire clamp fixing plate 3. The rotating block 401 is rotatably connected to the wire clamp fixing plate 3 through the rotating groove 101. The rotating block 401 adjusts the angle between the lead crimping tube 2 connected to it and the wire clamp fixing plate 3 through the rotating groove 101.

[0030] In this embodiment, the interior of the wire clamp fixing plate 3 and the rotating block 401 are both provided with a limiting hole 102 adapted to the limiting column 501. The limiting column 501 passes through the wire clamp fixing plate 3 through the limiting hole 102, and the bottom end is plugged into the wire clamp fixing plate 3 and passes through the rotating block 401. The limiting column 501 passes through the limiting hole 102 from the outer edge of the wire clamp fixing plate 3 to connect the rotating block 401 with the wire clamp fixing plate 3, and the extended end of the limiting column 501 is plugged into the interior of the wire clamp fixing plate 3 to fix the position.

[0031] In this embodiment, a limiting block 502 is fixed on the outer side of the limiting column 501, and a slot 403 adapted to the limiting block 502 is fixed on the inner side of the limiting hole 102. The limiting block 502 is made of elastic material. The limiting block 502 is stuck in the slot 403 in the upper limit hole 102 of the rotating block 401, thereby fixing the position of the rotating block 401 in the rotating groove 101.

[0032] In addition, the materials of the elastic block and the limiting block 502 need to be selected without affecting the conductivity.

[0033] In this embodiment, a C-shaped copper busbar is provided between the mounting base plate 1 and the lead crimping tube 2. The C-shaped copper busbar 6 is connected to the mounting base plate 1 and the lead crimping tube 2 by welding or by bolts and tinning, thereby ensuring the contact surface between the C-shaped copper busbar 6, the mounting base plate 1 and the lead crimping tube 2, and ensuring that the large current can be withstood without burning the wire clamp.

[0034] Specifically, the mounting base plate 1 is welded to the wire clamp fixing plate 3, and the transition angle is 90 degrees to 180 degrees, which can be customized according to actual requirements. It is made of single or multiple materials such as aluminum, aluminum alloy, copper, copper-aluminum, and steel, and can be integrated and customized according to actual wiring requirements. The number of lead crimping tubes 2 on the outside of the wire clamp fixing plate 3 can be customized into single-lead or multi-lead according to actual needs, and fastening bolts can be used on the mounting base plate 1;

[0035] Insert the rotating block 401 into the rear side of the lead crimping tube 2 through the connecting column 402, align the rotating block 401 with the rotating groove 101, and insert the rotating block 401 into the rotating groove 101 according to the required angle. Then, pass the limiting column 501 through the limiting hole 102 and the outer plate of the wire clamp fixing plate 3, penetrate the rotating block 401, and plug into the inner part of the wire clamp fixing plate 3. When passing through the rotating block 401, the limiting block 502 on the limiting column 501 is elastically snapped into the internal slot 403 of the rotating block 401 to limit the rotating block 401.

[0036] Taking into account that there are certain differences in the angle adjustment of the above-mentioned adjustment structure, when precise adjustment is required, pull out a part of the limit column 501, and ensure that the limit block 502 on the limit column 501 at this time exits the slot 403, and the front end of the limit column 501 remains in the rotating block 401, and the limit block 502 is squeezed into the limit hole 102 of the wire clamp fixing plate 3. Manually control the lead crimping tube 2 to rotate on the outer surface of the limit column 501 for secondary adjustment, and repeat the above-mentioned limiting action to improve the accuracy of the angle.

[0037] The components of the utility model, such as the mounting base plate 1, the lead crimping tube 2, the wire clamp fixing plate 3, the rotating block 401, the connecting column 402, the limiting member 5, the limiting column 501, the limiting block 502, and the C-shaped copper bus 6, are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
