Ground wire circular winding and unwinding device

Abstract

The invention discloses a ground wire circular winding and unwinding device. The ground wire circular winding and unwinding device comprises a cylinder body, the cylinder body is horizontally arrangedabove the ground, and a cylinder cover is vertically arranged on the side face of the cylinder body. The ground wire circular winding and unwinding device is drop-resistant, collision-resistant, longin service life, relatively low in production cost and very suitable for daily detection work of a distribution network and a transformer substation by adopting the cylinder body and the cylinder cover which are made of rubber materials, and the improved winding and unwinding device can be rapidly wound and unwound a ground wire by rotating a handle, reduces the working time, and is convenient and rapid; and the labor intensity of workers is reduced while the working efficiency is improved, no acute angle edge protrudes out of the appearance, and personnel scratching is avoided.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to a circular retractable device for grounding wires. Background technique [0002] The ground wire is widely used in the operation, maintenance and repair of distribution lines to prevent personal electric shock. At present, the power supply lines of the distribution network are long, the distribution area is wide, the network structure is complex, the equipment types are diverse, the allocation rate of distribution automation is low, and the geographical location The environment is complicated, resulting in many maintenance operations and a large number of grounding wires, which leads to a decrease in power supply reliability; the existing grounding wire consists of a 12 to 15-meter grounding wire body, a grounding needle, and an insulating operating rod. The top of the insulating operating rod is fixed with a Conductor clamp; the existing grounding wire composition...
