Description

Special set of grounding wires for branch boxes

Technical field:

The utility model relates to a grounding device used for power equipment in a power system, in particular to a special set of grounding wires for branch boxes.

Background technique:

The cable branch box is an intermediate part between cables and cables, and cables and other electrical equipment in the distribution line. Its connection combination method is simple, convenient, flexible and widely used. When overhauling the branch box, according to the relevant national safety regulations, a qualified grounding wire should be installed on the power distribution device before the relevant overhaul can be carried out. Injury to maintenance personnel. When the maintenance personnel overhaul the branch box now, most of the maintenance personnel wear insulating gloves, then wind the thin copper wires on the three-phase cable terminals respectively, and then ground them. Since there are corresponding insulating shields on the three-phase cable terminals, it is very inconvenient to operate the grounding wire, and the connection is not firm, and the operation method does not comply with the corresponding national safety regulations, and it is easy to cause damage to maintenance personnel. Hurt, not safe.

Utility model content:

The utility model provides a special set of grounding wires for branch boxes, which has the advantages of simple structure, convenient operation, firm connection, safety and reliability, and solves the problems existing in the prior art.

The technical scheme adopted by the utility model for solving the above-mentioned technical problems is: it includes three insulated grounding rods, and the three insulated grounding rods are respectively connected through multi-strand annealed copper wires, and then connected with the grounding clamp.

The insulated grounding rod includes an insulating rod, the front end of the insulating rod is fixedly connected with a grounding rod, and the rear end of the grounding rod is movably socketed with a rotating grounding body, and multiple soft copper wires are fixed on the rotating grounding body by screws. A screw cap is provided inside the front end of the rod.

The utility model adopts three insulated grounding rods, and the three insulated grounding rods are respectively connected through multiple strands of soft copper wires, and then connected with the grounding clamp. There is a nut inside the front end of the grounding rod, and the rotating grounding body is movably socketed at the rear end of the grounding rod, and the multi-strand annealed copper wire is fixed on the rotating grounding body through screws, so that when wearing insulating gloves and holding the insulating rod in hand, , It is convenient to firmly connect the grounding wire with the conductor end, so that maintenance personnel can avoid touching the grounding wire or ungrounded conductors, so as to prevent induction electric shock, and make the operation comply with the corresponding national safety regulations. It is simple, convenient, safe and reliable.

Fig. 2 is an enlarged view of part A in Fig. 1 .

In the figure 1. Insulation rod; 2. Grounding rod; 3. Rotating grounding body; 4. Nut; 5. Multi-strand annealed copper wire; 6. Grounding clip.

Detailed ways:

In order to clearly illustrate the technical features of this solution, the utility model will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

As shown in the figure, the utility model includes three insulated grounding rods, and the three insulated grounding rods are respectively connected through multi-strand annealed copper wires 5, and then connected with the grounding clip 6. The insulated grounding rod includes an insulating rod 1, a grounding rod 2 is fixedly connected to the front end of the insulating rod 1, and a rotating grounding body 3 is movably socketed at the rear end of the grounding rod 2, and the multi-strand annealed copper wire 5 is fixed on the rotating On the ground body 3 , a nut 4 is provided inside the front end of the ground rod 2 .

When in use, maintenance personnel wear protective equipment, open the branch box, and remove the protective covers on the three-phase cables. Then ground the ground clamp 6 first, then hold the insulating rod 1, and screw the nut 4 at the front end of the ground rod 2 to the corresponding three-phase cable, so that the multi-strand annealed copper wire 5 passes through the rotating ground body 3 and the ground rod 2. It is firmly connected to the conductor end, so that the operation complies with the relevant national safety regulations, which is simple, convenient, safe and reliable.
