Portable and detachable high-voltage cable butt joint box grounding wire and using method thereof

Abstract

The invention discloses a portable and detachable high-voltage cable butt joint box grounding wire. The grounding wire comprises a cable, one end of the cable is connected with a connecting piece, the connecting piece is provided with a connecting nut, the connecting nut is matched with a screw on a butt-joint box, and the cable is electrically communicated with the connecting piece. The connecting piece further comprises a rotating rod, a cable connecting piece and a rotating piece, the rotating rod is connected with the cable connecting piece through the rotating piece, the rotating rod and the rotating piece are electrically communicated with the cable connecting piece, the cable is connected to the cable connecting piece, and the connecting nut is connected to one end of the rotating rod; and the grounding wire further comprises an an operating rod, an inner hole is formed in one end of the operating rod, one end of the inner hole is open, the other end of the inner hole is closed, and the inner hole can be matched with the end, away from the connecting nut, of the rotating rod. The problems that in the prior art, a grounding wire cannot be used for a cable butt joint box, the power failure range is enlarged, and the workload of workers is increased are solved.

Description

technical field [0001] The invention relates to the field of high-voltage cable line power distribution equipment, in particular to a portable and detachable grounding wire of a high-voltage cable docking box and a method of using the same. Background technique [0002] In the existing 10KV cable line power distribution equipment, the switch box and ring network cabinet are generally equipped with grounding devices, while the cable connection box is not equipped with grounding devices. If the work is grounded, it is necessary to stop the upper-level switch box and close the ground knife to meet the work needs, but it expands the scope of power outages and increases the workload of operators. The existing grounding wires are specially designed for cable connection, and the three-phase busbar bolts in the cable connection box need to be grounded, and the existing grounding wires cannot be used in the cable connection box. SUMMARY OF THE INVENTION [0003] In order to solve ...

AI Technical Summary

Problems solved by technology

[0002] In the existing 10KV cable line power distribution equipment, the switch box and the ring network cabinet generally have a grounding device, but the cable connection box is not equipped with a grounding device. If the work is grounded, the switch box at the upper level must be stopped and the ground knife must be closed to meet the work needs, but the scope of power failure is expanded and the workload of operators is increased.

The existing grounding wires are specially designed for cable connection, and the place that needs to be grounded in the cable connection box is the three-phase busbar bolts, and the existing grounding wires cannot be used in the cable connection box
