technical field

The utility model relates to a grounding wire device for an outdoor busbar of a transformer, which belongs to the technical field of transformer equipment.

Background technique

During transformer maintenance work or annual line (transformer) cleaning, it is necessary to install a grounding wire on the transformer for power outage maintenance to discharge the residual charge of the disconnected part of the equipment due to grounding. This is a reliable safety measure to prevent sudden power calls at the workplace. The purpose is to protect the life safety of the staff and prevent the staff from being injured by the induced voltage that may be generated by the power failure equipment. In the specific operation, the grounding wire clamp should be clamped to the outdoor busbar of the transformer. Since the carrying capacity of the outdoor low-voltage busbar of the transformer is relatively large, this determines that the thickness of the busbar on the low-voltage side of the transformer is greater than that of other busbars. The busbar on the outdoor low-voltage side of the transformer is generally It consists of three layers, each layer is 120mm wide and 10mm thick. The maximum opening of the standard grounding line card is 65mm, which is too small. The busbar cannot be completely stuck in the grounding line card, and there is no position and This has caused the practical problem that it is difficult for operators to hang the grounding wire on the outdoor low-voltage busbar of the transformer during the power outage of the equipment.

Utility model content

In the grounding line card, the grounding line can play a role in a standardized and effective manner, ensuring the reliable grounding of the equipment and avoiding potential safety hazards.

The technical scheme that solves the above-mentioned technical problem is:

A device for suspending grounding wires on the outdoor busbar of a transformer, which includes a connecting plate, a vertical plate and an articulated plate, the connecting plate, the vertical plate and the articulated plate are all rectangular brass plates, and the surface of the connecting plate Placed horizontally, there are screw holes on the surface of the connecting plate, the length direction of the vertical plate is perpendicular to the horizontal plane of the connecting plate, the lower end of the vertical plate is connected with one end of the connecting plate, and the upper end of the vertical plate is connected with one end of the connecting plate connected, the plate surface of the hitch plate is perpendicular to the horizontal plane, and the length direction of the hitch plate is parallel to the horizontal plane.

The above-mentioned device for hanging the grounding wire on the outdoor busbar of the transformer, the other end of the hitch plate is connected to the retaining hook, the retaining hook is a rectangular brass sheet, the plane of the retaining hook is placed vertically, and one side of the retaining hook is connected to the connecting plate , There is a bending angle of 70-90 degrees between the plane of the retaining hook and the plane of the hitch plate.

In the above-mentioned device for hanging the grounding wire on the outdoor busbar of the transformer, there are two parallel screw holes on the surface of the connecting plate, and the fastening bolts pass through the screw holes to fix the connecting plate on the upper surface of the first layer of the busbar. The crotch at the upper end of the line is hung on the plate surface of the hitch plate from top to bottom.

The beneficial effects of the utility model are:

The connection plate of the utility model is fixedly connected with the bus bar, and the ground connection line is hung on the surface of the hitch plate, so that the utility model is firmly connected with the bus bar, and the connection of the ground connection line is very convenient. The articulated plate slips off, and at the same time, because the utility model is made of brass, it has good electrical conductivity. The utility model is simple in structure and easy to use, solves the problem that the grounding wire is not easy to hang on the busbar on the outdoor low-voltage side of the transformer and is not firmly connected, reduces the damage of the induced voltage to the staff, and has good popularization and application value.
