Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a novel portable grounding wire clamp. Background Art

[0002] In recent years, the power grid has developed rapidly, and the mileage of ultra-high and extra-high voltage lines has increased dramatically. Transmission lines have been exposed to the external environment for a long time and are easily affected by external forces or the natural environment and may fail. In order to maintain the transmission lines in good working condition, they need to be inspected and maintained regularly or according to the status of the equipment.

[0003] When the transmission line is shut down for maintenance, hanging working grounding wires at each end of the work section is one of the technical measures to ensure safe work on the line. Its main function is to introduce the residual charge of the power-off line into the earth, eliminate the induction electricity of the adjacent live line, and prevent the line from suddenly sending power. At present, the grounding wire clamps used on ultra-high and extra-high voltage transmission lines are mostly impact-type duckbill-type wire clamps. The grounding wire clamps in this way are composed of grounding clamps, insulating ropes, soft copper wires, conductor clamps, etc. When in use, overcome the spring tension to open the clamps, and use a small push rod to push the two clamps open. Through the downward impact force, the supporting push rod collides and slides off the pins, and the closed clamp bites the conductor.

[0004] This structure has low sensitivity and is not easy to trigger. In addition, due to structural defects, the grounding force of the grounding clamp is low, the grounding is not reliable, and the opening is downward when in use. This type of clamp has the potential safety hazard of falling off when in contact with the wire due to collision, pulling or strong wind. At the same time, the inner diameter of the wire clamp of this structure is fixed, but the diameter of the wire is different, so the wire clamp and the wire cannot be tightly combined. Once the left and right clamps are opened, the wire is very easy to fall off from the arc-shaped slot, and the wire end and the ground wire end are disconnected immediately, the ground wire loses its protection function, and people are very likely to get electric shock. Summary of the invention

[0005] According to the problems mentioned in the background technology, the wire of the existing grounding wire clamp is very easy to fall off from the arc-shaped slot, and the wire end and the ground wire end are disconnected immediately, the grounding wire loses its protection function, and people are very likely to get electric shock. The present invention provides a new portable grounding wire clamp.

The grounding wire clamp can be easily removed without causing damage to the wires. BRIEF DESCRIPTION OF THE DRAWINGS
