Description

a ground terminal

technical field

The utility model relates to a grounding terminal, which is used for grounding protection occasions of power equipment in a power system.

Background technique

One of the technical measures to ensure the safe operation of the power system is to install a grounding wire, and the grounding wire of the power equipment is connected to the grounding body through the grounding terminal. At present, after most substations have changed the safety measures of the grounding knife switch to the grounding wire, because the existing grounding terminal is welded at the designated position, the grounding wire and the grounding terminal are not matched, resulting in unreliable grounding of the maintenance equipment and winding grounding phenomenon; Temporary The shell of the power box, the shell of the electric welding machine, and the shell of the mobile electric tool must be reliably grounded, but in actual work, it cannot be reliably grounded because there is no connectable ground terminal.

Contents of the invention

In order to solve the above problems, the purpose of the utility model is to provide a grounding terminal with simple structure and reliable grounding.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

The grounding terminal is made of iron or copper and integrally formed, including a terminal body, the terminal body is composed of a grounding wire connecting part and a grounding body connecting part; the grounding wire connecting part is a flat rectangular parallelepiped, and the grounding wire connecting part There is a connecting hole, one end of the connecting hole is provided with a connecting pipe, and there are two connecting bolts and nuts on the connecting part of the grounding wire; the connecting part of the grounding body is a square, with a square groove and a bolt hole on one side, and the bolt hole is located in the square sides.

Due to the adoption of the above-mentioned technical scheme, the utility model has the following advantages:

The grounding terminal can realize 100% reliable connection between the grounding wire of the power equipment and the grounding grid, and reduce the occurrence rate of violations caused by unreliable installation of the grounding wire from 34.8% to 0%. It is also simple in structure, easy to use, and low in cost. It is also small in size, light in weight, and easy to carry. It is suitable for different types of materials and environments connected to the ground grid on site. It is flexible and quick to disassemble and assemble, and the disassembly time does not exceed 20 seconds.

Detailed ways

The utility model is described in detail in conjunction with the accompanying drawings and embodiments as follows: As shown in Figures 1 and 2, the grounding terminal described in the utility model is made of iron or copper and integrally formed, and includes a terminal body, which is formed by the grounding terminal. The connecting part 1 of the grounding wire and the connecting part 4 of the grounding body are composed; the connecting part of the grounding wire is a flat rectangular parallelepiped. A connecting bolt 3 and a nut; the grounding body connecting part 4 is a cube, one side is provided with a square groove 6 and a bolt hole 5, and the bolt hole is located on both sides of the square groove.

At present, the grounding body commonly used in power systems is formed by connecting metal components such as flat iron, channel steel, angle steel, and round steel to the ground grid. The grounding ends of commonly used grounding wires are rod type and crimping clamp type. When the grounding terminal is in use, insert the grounding body flat iron, channel steel, angle steel or round steel into the square groove 6 of the grounding body connection part 4, and crimp it with bolts; the grounding end of the grounding wire of the power equipment in the maintenance state uses For the rod type, pass the ground rod through the connection hole of the ground wire connection part 1, and press the connection pipe 2 with the ground rod crimping nut; On two or one of the connecting bolts 3 of the connecting part 1, the clamp is fixed on the upper end surface of the connecting part of the grounding wire, and then locked with a nut; the shell of the mobile electrical equipment is grounded, such as: the shell of the power box, the shell of the electric welding machine, the mobile When the shell of the electric tool is grounded, crimp the special grounding wire on the shell to the connecting bolt 3 of the grounding wire connection part 1, and lock it with a nut; so that the grounding wire of the equipment is reliably connected to the grounding grid.
