A portable grounding wire device for a substation and its usage method

Abstract

The invention relates to a portable ground wire connection device for a substation and a use method. Insulating rods are raised with two hands, clamping and embedding parts are hooked on an alternating current phase line of a substation line, the insulating rods are downwards pulled, the alternating current phase line is clamped in two elastic pieces of the clamping and embedding parts to be contacted with sharp teeth, the insulating rods are downwards pulled, connectors II are separated from connectors I, the clamping and embedding parts of the connectors II are firmly suspended on the alternating current phase line of the substation line, ground wire connection can be completed, and overhaul or detection work is performed; when a ground wire is removed, the insulating rods are raised with two hands, the connectors I on the insulating rods are attracted with connectors together, the insulating rods are upwards raised, and the alternating current phase line is separated from the clamping and embedding parts. The portable ground wire connection device is simple in structure and convenient to use and carry, can be used no matter whether oxidation layers exist on the line and whether the line is covered with ice, good contact of a bus with the ground wire of the line can be ensured, sudden electricity supply and static electricity supply due to induction can be prevented, and personal safety of workers on power failure equipment and the line is guaranteed.

Description

technical field [0001] The invention relates to a grounding wire device, in particular to a portable grounding wire device for a substation and a use method thereof. Background technique [0002] When the engineering and technical personnel of the substation repair or test the substation equipment such as: transformers, transformers, switches, lightning arresters, etc., it must be carried out under the condition that the equipment to be repaired or tested has a good and reliable grounding state, otherwise the grounding is not good , When the staff touch the equipment with their hands, they will feel numbness. In severe cases, they will be bounced by the induction electric shock. Because the residual voltage is high, when people touch the induction voltage, they will be nervous and their muscles will shrink, especially when working at heights. Danger. [0003] The causes of induced voltage are as follows: [0004] 1. When overhauling and maintaining some equipment that has ...
