Grounding device convenient to carry for insulation wire pay-off rack

Abstract

The invention discloses a convenient and portable grounding device for an insulated wire pay-off frame, which is mainly composed of a wire reel, a wire reel iron frame, a wire reel center shaft, an insulated wire, a puncture wire clamp, a wire release rack, a ground electrode and an annealed copper wire. The wire reel is equipped with a wire reel iron frame, the center of the wire reel iron frame is provided with a wire reel center axis, and an insulated wire is arranged on the wire reel, and the end of the insulated wire is connected to an annealed copper wire, and the annealed copper wire is connected to the wire reel by a puncture clamp The iron frame, the central axis of the wire reel is connected with the pay-off frame. The device of the present invention has completely changed the traditional unwinding method, which is time-consuming, labor-intensive, easy to damage the insulating layer of the wire, easy to dump and unsafe, etc. , The convenient and reliable grounding device for the insulated wire pay-off frame solves the problem that the insulated wire cannot be grounded during the release process, and has been applied in practice.

Description

technical field [0001] The invention belongs to the technical field of pay-off racks, and in particular relates to a conveniently portable grounding device for an insulated wire pay-off rack. Background technique [0002] In recent years, the power safety situation is relatively severe, and various accidents have occurred, among which casualties caused by the release of wires have also occurred from time to time. At present, the power supply bureau uses the release end to play the role of grounding through pulleys and iron brazing during the process of releasing bare wires. , this method is simple and effective, but it is not suitable for insulated wires. There is no grounding device during the deployment of insulated wires, which poses a certain safety hazard. At present, the line corridor is complicated, and there are many high and low voltage crossings. The 10kV line crosses with the high voltage level line to generate an induced current, and there are some high and low ...

[0002] In recent years, the power safety situation is relatively severe, and various accidents have occurred, among which casualties caused by the release of wires have also occurred from time to time. At present, the power supply bureau uses the release end to play the role of grounding through pulleys and iron brazing during the process of releasing bare wires. , this method is simple and effective, but it is not suitable for insulated wires

There is no grounding device in the process of laying insulated wires, which creates a certain potential safety hazard

At present, the line corridor is complicated, and there are many high and low voltage crossings. The 10kV line crosses with the high voltage level line to generate an induced current, and there are some high and low voltage power supply phenomena at the intersection with the low voltage line. This series of phenomena will have a certain impact on safe production. , especially increasing the difficulty of casting wires
