Description

Hand-held high-voltage grounding wire

technical field

The utility model relates to a connection and fixing device for electric facilities, in particular to a hand-held high-voltage grounding wire.

Background technique

The ground wire is an essential safety tool for electrical work. It is easy to carry and can be used flexibly on site, so it is also called a portable ground wire. The hanging ground wire is a safety barrier to protect the maintenance personnel, which can prevent the harm to the human body caused by a sudden call. In actual production, the 10kv hand-held high-voltage grounding wire is the main grounding method for the high-voltage busbar of the 35kv substation. Its purpose is to prevent sudden calls from equipment and lines, eliminate induced voltage, and be a temporary grounding device for discharging residual charges.

When in use, first fix the copper terminal on the grounding wire on the grounding clip or the grounding pin, and then clamp the electric clips of each item on the busbar or other contacts of the fixed phase, and remove the grounding wire in the opposite order operate.

In use, due to the frequent use of the grounding wire and the seemingly simple operation, it is easy to paralyze people's thinking, and its importance is often overlooked by people. Because the length of the grounding rod connected to the connection clip is inconsistent with the width of the 10kv high-voltage cabinet, the resulting It is inconvenient to operate, because the inclination angle of itself cannot be adjusted, resulting in an unstable center of gravity, and it is easy to fall off under external force interference. In addition, the electric connection clip is easy to fall off because the clip is not tightly connected to the electric point or the contact is not tight, resulting in a potential safety hazard.

Utility model content

The purpose of the utility model is to provide a hand-held high-voltage grounding wire with more stable connection.

The utility model includes two parts, a grounding wire and a grounding rod, and a universal joint is installed between the grounding wire and the grounding rod, and the connecting part of the universal joint is connected with a locking bolt, and the universal joint is covered with an insulating layer.

The utility model has the advantages of: 1. Make the connection between the electric clip and the bus bar more compact, effectively prevent the electric clip from falling off, and improve the safety factor; 2. Due to the various types of high-voltage cabinets in the equipment transformation, the equipment can Reduce duplication of investment.

Description of drawings

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

Fig. 1 is a schematic view of the working state of the utility model.

Detailed ways

The utility model includes two parts, the ground wire and the ground rod. The ground wire 1 and the ground rod 5 are equipped with a universal joint connection 4, and the connection of the universal joint connection 4 part is connected with a locking bolt, and the universal joint is covered with an insulating layer. 3.

When working, fix the copper terminal 2 on the grounding wire on the grounding clip or the grounding needle, and then clamp the electric connecting clip 6 of each item on the bus bar or other contacts of the fixed phase, and remove the grounding wire. sequential operation.

The existence of the universal joint connection 4 can adjust the angle between the grounding wire 1 and the grounding rod 5 according to the working conditions, so that the center of gravity of the entire hand-held high-voltage grounding wire is in a stable position, making the installation structure more stable, and the contact points The force is more stable, reducing the possibility of falling and reducing safety hazards.

In use, it is necessary to check the electricity before connecting the ground wire, and the purpose of the electricity inspection is to confirm whether the power has been cut off on site, which can eliminate the human error of wrong power failure and non-power failure, and prevent the ground wire from being charged.
