Description

A substation ground wire extension wire connector

technical field

The utility model relates to the technical field of electric equipment, in particular to a connection head for an extension line of a substation grounding line.

Background technique

Substation operators often encounter a problem when hanging the ground wire, that is, the length of the ground wire itself is not enough to complete the hanging operation. When encountering this kind of situation, the operator usually temporarily removes a wire from other grounding wires as an extension wire, and connects one end to the three-phase grounding head of the grounding wire and the other end to the grounding stake. Although the above method can solve the problem of insufficient length of the grounding wire, it is often time-consuming and laborious to operate. The connected extension wire does not have a special adapter member, the connection is not stable enough, and tools such as adjustable wrenches are required to operate, which is inconvenient to operate and low in work efficiency.

Utility model content

Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a substation grounding wire extension wire connector with convenient operation, stable connection and high working efficiency.

In order to achieve the above purpose, the technical solution provided by the utility model is: a substation grounding wire extension wire connector, including a conductive connecting body, the connecting body is an L-shaped structure connected by a vertical connecting plate and a horizontal connecting plate , the vertical joint plate is provided with a joint through hole, the horizontal joint plate is provided with a threaded post, the threaded post is fitted with a fixing nut threaded with the threaded post, and the threaded post and the vertical joint plate are located on the same side of the horizontal joint plate.

In the above scheme, by opening a joint through hole on the vertical joint plate, and a threaded column is provided on the horizontal joint plate, when in use, pass the three-phase ground head bolt of the ground wire through the joint through hole of the vertical joint plate and use the nut Fix it, and then put the copper ring connecting piece at one end of the single extension line on the threaded column, and then tighten it with the fixing nut to complete the connection of the extension line. Since no adjustable wrench and other tools are required for operation, the operation is convenient and the connection is stable. And fast. Among them, the connecting body is set as an L-shaped structure, and the threaded column and the vertical connecting plate are located on the same side of the horizontal connecting plate, so that the grounding wire and the extension wire can extend in the same direction after being connected, and it is convenient to carry out inspections on the extension line joint and its vicinity. Insulation treatment to ensure safety.

Further, the tails of the above-mentioned vertical connecting plates and horizontal connecting plates are all square plate structures, the joint through holes are located on the square plate structure at the rear of the vertical connecting plates, which facilitates the opening of the joint through holes, and the threaded columns are located in the square plate structure at the rear of the horizontal connecting plates. On the plate structure, the threaded column can be fixed more firmly.

Further, the above-mentioned fixing nut is a wing nut, which is convenient for screwing the nut.

Further, the above-mentioned vertical connecting plate and horizontal connecting plate are integrated to ensure structural stability and simplify the manufacturing process.

The grounding wire extension wire connector of the utility model has a simple and stable structure, and can be completely manually connected to the grounding wire and the extension wire without using special tools for operation. The utility model has the advantages of convenient operation, high working efficiency and reliable connection.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Example

As shown in Figure 1-3, the utility model provides a substation grounding wire extension wire connector, including a conductive connector 1, the connector 1 is a L connected by a vertical connecting plate 11 and a horizontal connecting plate 12 The vertical plate 11 and the horizontal plate 12 are integral structures, the tails of the vertical plate 11 and the horizontal plate 12 are square plate structures, and the middle position of the square plate structure at the tail of the vertical plate 11 is provided with a joint The through hole 11, the middle position of the square plate structure at the tail of the horizontal connecting plate 12 is provided with a threaded post 2, the threaded post 2 is set with a fixing nut 3 threaded with the threaded post 2, and the threaded post 2 and the vertical connecting plate 11 are located On the same side of the cross-connection plate 12, the above-mentioned fixing nut 3 is a wing nut, which is convenient for screwing the nut.

When the utility model is in use, pass the three-phase ground head bolt of the ground wire through the joint through hole 111 of the vertical joint plate 11 and fix it with nuts, and then put the copper ring connecting piece at one end of the single extension line on the cross joint plate 12. On the threaded post 2, screw the butterfly nut into the threaded post 2 to fix the pair of copper ring connecting pieces, and finally use insulating tape or insulating hose to insulate the extension line connector and the connection between the extension line and the grounding line and the extension line joint , to complete the extension cable connection.
