Description

Technical Field

[0001] The invention relates to the technical field of power equipment testing, and in particular to a connector for testing power grid equipment. Background Art

[0002] The connector is a connector commonly used in power grid equipment testing. It is an instrument transformer connector. This connector is usually used to test the connection of instrument transformers and current transformers. They have reliable electrical contact and high voltage resistance to ensure the accuracy and safety of test results. The connectors for power grid equipment testing include:

[0003] 1. High current plug connector: used to connect high current devices such as circuit breakers and cables.

[0004] 2. Connectors with high voltage insulation: used to test high voltage equipment such as transformers and generators.

[0005] 3. Tube connector: used to connect the ground wire and grounding equipment to ensure a good grounding system.

[0006] 4. Antenna connector: used to connect telemetry equipment to monitor power grid signals and data.

[0007] 5. Safety Disconnect Connector: Used to safely disconnect power to grid equipment during testing or maintenance.

[0008] These connectors can be selected based on different equipment and test requirements, and play a key role in the test process to ensure accuracy and safety.

[0009] The patent document (application number: 201410265248.0, application date: 2014.06.13) discloses a connector for testing power equipment in a power grid. The connector is provided with a first slot and a second slot on the left and right sides of both ends of a connecting plate, and the middle part of the connecting plate is rotatably fixed on the vertical axis of the base plate. When in use, the connecting plate is pushed to rotate around the vertical axis on a horizontal plane, so that the power connection column on the base plate is inserted into the first slot, and at the same time, the power column of the device under test is inserted into the second slot. Since the conductive gasket provided in the first slot groove is electrically connected to the conductive gasket in the second slot groove, the power connection column and the power column of the device under test can be connected.

[0010] Although the above connector solves the shortcomings of traditional connectors, it also has several disadvantages. First, if the power poles of the device under test are relatively dense, the connecting plate in the middle part of the device cannot rotate freely; second, if the power poles of the device under test are not in a straight line, some connecting plates of the device cannot be used. To address the above problems, we propose a connector for testing power grid equipment. Summary of the invention

[0036] The sliding assembly facilitates the horizontal movement of the clamp ring assembly to better test power poles at different positions. The fixing mechanism facilitates the fixing of the slider plate 11 to prevent it from moving after position adjustment and affecting the test effect. The clamp ring assembly facilitates the fixing of the power pole to ensure the test effect. The multi-directional limit member can fix the placement ball 9 in the X-axis direction and the Y-axis direction so that the placement ball 9 is in the placement bin 8.

[0037] The sliding assembly of the present invention includes a slider 10 fixedly connected to a fixed plate 1 and a slider plate 11 adapted to the slider 10; the slider plate 11 is fixedly connected to the sleeve 2, and the slider plate 11 can move in the direction of the slider 10, thereby being able to adjust the position of the clamp ring assembly.

[0038] The fixing mechanism of the present invention includes a strip groove 12 provided on the slider 10; a pressure block 13 is provided in the strip groove 12; a threaded rod 14 is threadedly connected to the slider plate 11; the threaded rod 14 is rotatably connected to the pressure block 13; an anti-slip pattern is provided on the end surface of the pressure block 13 away from the threaded rod 14, and the extrusion pressure between the pressure block 13 and the slider 10 can be adjusted by the threaded rod 14. The slider plate 11 is fixed by the extrusion pressure of the two, and the anti-slip pattern increases the extrusion effect to ensure the stability of the fixation.

[0039] The clamp ring assembly of the present invention includes a lower half ring 15 fixedly connected to the support rod 3; an upper half ring 17 is rotatably connected to the lower half ring 15 via a rotating member 16; the ends of the upper half ring 17 and the lower half ring 15 away from the rotating member 16 are connected by a connecting member, and the rotating member 16 includes an extension plate fixedly connected to the lower half ring 15 and an L-shaped plate fixedly connected to the upper half ring 17; the connecting member includes a second extension plate 18, the ends away from the rotating member 16 are respectively fixedly connected to the upper half ring 17 and the lower half ring 15; a second threaded rod 19 is threadedly penetrated on the two second extension plates 18; a nut sleeve 20 is threadedly sleeved on the second threaded rod 19. A slot is provided on the extension plate; one end of the L-shaped plate is arranged in the slot and is rotatably connected to the extension plate through a rotating rod; the upper half ring 17 and the lower half ring 15 in the clamp ring assembly are used to fix the power column, and the rotating part 16 ensures that the upper half ring 17 can be rotated to fit the lower half ring 15, and the upper half ring 17 and the lower half ring 15 are fixed by the second threaded rod 19 and the nut sleeve 20.

[0040] The corrugated sleeve 4 and the second corrugated sleeve 5 of the present invention are both made of elastic material. The corrugated sleeve 4 and the second corrugated sleeve 5 made of elastic material have the ability of recoverable deformation, so that the placement ball 9 can squeeze the corrugated sleeve 4 and the second corrugated sleeve 5 to deform.

[0041] The fixing plate 1 of the present invention is provided with a plurality of power sockets 21 ; the upper half ring 17 is provided with a conductive portion, and the conductive portion is connected to the power sockets 21 on the fixing plate 1 through a wire.

[0042] The principle of the present invention is as follows: the slider plate 11 can slide in the direction of the slider 10 to adjust the position of the clamp ring assembly. After the adjustment, the threaded rod 14 is rotated to drive the pressure block 13 to move in the strip groove 12, squeeze and support the slider 10, and fix the slider plate 11 to prevent it from moving.

[0043] When the height of the clamp ring assembly needs to be adjusted, the support rod 3 is pulled up and down, and the placement ball 9 on the support rod 3 moves up and down, squeezing the protrusion 6 on the corrugated sleeve 4. The protrusion 6 forms an elastic deformation, and the placement ball 9 can enter the placement bin 8 at the upper and lower ends from one of the placement bins 8 to adjust the height of the clamp ring assembly. After adjusting to different placement bins, the vertical position of the support rod 3 can be fixed due to the obstruction of the two adjacent protrusions 6 on the corrugated sleeve 4 to prevent it from moving up and down when there is no external force adjustment.

[0044] When the angle of the clamp ring assembly needs to be adjusted, the support rod 3 is rotated, and the placement ball 9 on the support rod 3 rotates around the support rod 3, squeezing the protrusion 6 on the second corrugated sleeve 5. The protrusion 6 on the second corrugated sleeve 5 is deformed, and the placement ball 9 can enter the placement bin 8 at the left and right ends from one of the placement bins 8 to adjust the angle of the clamp ring assembly. After adjusting to different placement bins 8, due to the obstruction of the two adjacent protrusions 6 on the second corrugated sleeve 5, the lateral position of the support rod 3 can be fixed to prevent it from rotating when there is no external force adjustment.

[0045] The power column is placed in the lower half ring 15, and the upper half ring 17 is rotated by the rotating member 16. The upper half ring 17 and the lower half ring 15 are conveniently connected together by the connecting member, so as to facilitate fixing the power column.

[0046] By adjusting the height of the clamp ring assembly in the upper and lower positions and the rotation direction, the clamp ring assembly has higher applicability.

[0047] Although the present invention has been disclosed as above in the form of a preferred embodiment, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the authorization requirements.
