A retractable portable multifunctional grounding wire

Abstract

The invention discloses a retractable and portable multifunctional ground wire, which comprises an insulating rod, a telescopic rod whose lower end is fixedly connected to the upper end of the insulating rod, a wire hook fixedly connected to the upper end of the telescopic rod through a plum blossom connector, and a wire hook fixed to the wire by a wiring fixing seat. The grounding down conductor on the outside of the hook, the ground wire winding clamp fixed on the outer side of the insulating rod, the grounding wire clamp fixedly connected to the lower end of the grounding down conductor, and the insulating anti-slip sleeve set on the lower end of the insulating rod. The telescopic insulation rod and the ground wire winding clamp reduce the overall length, making it easier for the operator to carry the pole; replace the insulation rod part according to different working conditions, and the working range is wider; the existing insulation rod is generally an epoxy resin tube, which is easy to damage , if the integral grounding wire damages the insulating rod, it may lead to the scrapping of the whole, wasting resources, and only replacing the insulating rod can save resources. The wire clamp and the grounding down-conductor are fixed by bolts, and the grounding down-conductor of different lengths can be replaced to adapt to poles of different heights.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance, in particular to a retractable and portable multifunctional grounding wire. Background technique [0002] The grounding line is the line directly connected to the earth, and it can also be called a safety return line. When it is in danger, it will directly transfer the high voltage to the earth, which can be regarded as a lifeline. In the power system, the grounding wire is an important tool to ensure the staff when there is an unexpected voltage on the equipment and lines that have been powered off. According to the regulations issued by the ministry, the ground wire must be 25mm 2 above bare copper flexible wires. [0003] (1) When hanging the ground wire: connect the ground clip first, then connect the electric clip; when removing the ground wire, first disconnect the electric clip according to the procedure, and then remove the ground clip. [0004] (2) Installation: Fix...

Problems solved by technology

[0008] However, the insulating pole of the grounding wire currently used is relatively long, which is inconvenient for the staff to carry on the pole; in special cases, such as cross-over lines or multi-circuit lines, when the upper line needs to be grounded, it cannot cross the lower line; at the same time, a dedicated Cable management bracket, a waste of redundant resources to a certain extent
