technical field

The utility model relates to a universal grounding piece.

Background technique

The grounding wire in the substation is connected to the grounding pile through the grounding piece; at present, the common grounding piece in the domestic substation includes the grounding piece connected to the microcomputer grounding pile and the grounding piece connected to the JS grounding pile. , When large-scale maintenance and centralized maintenance are carried out, the grounding wires of this station are often insufficient, and it is necessary to go to the adjacent substation for secondment. However, the grounding wires configured in each institute are not the same, and the grounding parts are not compatible with the grounding piles of the institute, and need to be temporarily restructured, which is time-consuming and laborious, and adds a lot of unnecessary workload to the production and operation.

Utility model content

The technical problem solved by the utility model is to provide a grounding piece that can be connected to both the microcomputer grounding stake and the JS grounding stake.

A further technical solution is: the smooth section is arranged between the terminal and the threaded section.

A further technical solution is: the diameter of the smooth section is larger than the diameter of the threaded section.

A further technical solution is: the threaded section is connected with a lock nut for clamping the ground stake of the microcomputer.

A further technical solution is: an installation plane is provided on the circumference of the terminal, and a connection hole is provided perpendicular to the installation plane.

A further technical solution is: the fixed end is provided with a locking head.

A further technical solution is: the locking head includes a protrusion arranged on the end surface of the fixed end, the protrusion is provided with a lock hole, and a microcomputer five-proof lock is hooked into the lock hole.

The beneficial effects of the utility model are: the fixed end of the universal grounding piece includes a threaded section and a smooth section, and the JS grounding pile can be connected through the smooth section, and the microcomputer grounding pile can be connected through the threaded section, which effectively solves the problem of substation after the optimal configuration of the grounding wire. Insufficient grounding wires in large-scale maintenance and centralized maintenance. After being transferred to adjacent substations, the versatility of grounding parts. There is no need to carry out repeated on-site restructuring, which greatly reduces the workload of grounding wire restructuring and improves work efficiency.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

Fig. 1 is the top view of the utility model;

Fig. 2 is the front view of the utility model.

Detailed ways

Referring to Fig. 1 and Fig. 2, a general grounding piece of the utility model is shown, which includes a fixed end connected to the ground stake and a terminal 1 connected to the ground wire. Smooth section of ground stake 2.

As shown in Figure 1 and Figure 2, the universal grounding piece is a cylinder, the cylinder includes three sections with different diameters, the smooth section 2 is located in the middle, the diameter of the terminal 1 is greater than the diameter of the smooth section 2, smooth The diameter of section 2 is greater than that of threaded section 3; round chamfers are made on the end faces of the universal grounding piece to prevent personal injury caused by sharp corners during operation.

The structure of the terminal, the terminal 1 is used as the part where the universal grounding piece is connected and fixed with the grounding wire, a mounting plane 11 for mounting screws is provided on the circumferential direction of the terminal 1, and a threaded connection hole is provided perpendicular to the mounting plane 11 12. Or the mechanism of the terminal can be changed to a flat protrusion on the end surface of the smooth section 2, and a connecting hole is arranged on the protrusion.

In order to improve the safety of the grounding operation, a locking head is provided on the threaded section 3 . The locking head includes a protrusion 4 arranged on the end surface of the threaded section 3, the protrusion 4 is provided with a locking hole 5, and the microcomputer five-proof lock is articulated in the locking hole, which can prevent the misoperation of the universal grounding piece, Only personnel with the key can remove the universal grounding piece from the grounding stake.

When the grounding pile matched with the substation is a microcomputer grounding pile, the threaded section 3 is connected with a locking nut to clamp the microcomputer grounding pile, one end of the microcomputer grounding pile is against the end face of the smooth section 2, and the other end is against the locking nut , the lock nut is a butterfly nut with a handle, and a metal gasket can be placed at the connection between the smooth section and the microcomputer ground stake to increase the contact area with the ground stake and the tightness of tightening.

When the substation is equipped with a JS ground pile, the general grounding piece is connected to the JS ground pile through the smooth section 2, and one end of the JS ground pile is against the end face of the terminal 1.

Those skilled in the art can make various changes and deformations to the utility model after they are familiar with the principle of the utility model, as long as they do not depart from the spirit of the utility model, all should belong to the scope defined by the appended claims of the utility model.
