Insulated wire pay-off rack grounding device applicable to power distribution cabinet

Abstract

The invention discloses an insulated wire pay-off rack grounding device applicable to a power distribution cabinet. The device is mainly composed of a wire coil, a wire coil iron frame, a wire coil middle shaft, an insulated wire, a penetrated clip, a pay-off rack, a grounding electrode and a soft copper wire. The wire coil iron frame is arranged in the wire coil, the wire coil middle shaft is arranged in the center of the wire coil iron frame, the wire coil is provided with the insulated wire, the tail of the insulated wire is connected with the soft copper wire, the soft copper wire is connected to the wire coil iron frame through the penetrated clip, and the wire coil middle shaft is connected with the pay-off rack. The adverse factors that traditional pay-off methods waste time and labor, wire insulation layers are likely to be damaged, toppling is likely to be caused and safety is low are thoroughly changed, the device is handy, convenient to carry, free of wire knotting, clamping or other phenomena, and easily, practically, conveniently and reliably applicable to the power distribution cabinet, solves the problem that the insulated wire cannot be grounded in the release process, and is applied in practice.

Description

technical field [0001] The invention belongs to the technical field of pay-off racks, and in particular relates to a grounding device for an insulated wire pay-off rack suitable for a power distribution cabinet. 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 ar...

[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
