Grounding device

Abstract

The invention discloses a grounding device. The grounding device is composed of a copper nose and a grounding clamp. The copper nose is composed of a compression connection pipe, a lead inlet and an installation part. The grounding clamp comprises a supporting frame, a clamping component and a screw. The outer surface of the installation part is provided with threads. One end of the compression connection pipe is connected with the installation part, and the other end of the compression connection pipe is provided with the lead inlet. A first threaded hole matched with the installation part is formed in the supporting frame. The grounding device has the advantages that the temporary grounding clamp is not prone to folding damage and poor connection, meanwhile, the effective energizing area is increased, requirements for grounding techniques of electric power according to rules are met, and accidents and personal injury caused by wrong grounding sequences are avoided.

Description

technical field [0001] The invention relates to a temporary grounding device for high and low voltage electrical circuits. Background technique [0002] At present, the grounding device of the high-voltage short-circuit grounding wire used in the power supply, generation, and distribution systems is realized by using a temporary grounding clip made of metal with a copper nose. There is also a through hole in the concave part on the top, and then through the through hole on the copper nose and the through hole on the ground clip in turn through the bolt, the copper nose and the ground clip are locked, but there are some problems in this connection relationship: due to The lead wire connected to the copper nose is affected by external force (wind force) or manual operation, which will inevitably drive the copper nose to swing left and right and up and down. On the one hand, it will easily cause the concave part of the copper nose to be folded and damaged. On the other hand, wh...

[0002] At present, the grounding device of the high-voltage short-circuit grounding wire used in the power supply, generation, and distribution systems is realized by using a temporary grounding clip made of metal with a copper nose. There is also a through hole in the concave part on the top, and then through the through hole on the copper nose and the through hole on the ground clip in turn through the bolt, the copper nose and the ground clip are locked, but there are some problems in this connection relationship: due to The lead wire connected to the copper nose is affected by external force (wind force) or manual operation, which will inevitably drive the copper nose to swing left and right and up and down. On the one hand, it will easily cause the concave part of the copper nose to be folded and damaged. On the other hand, when workers operate , When the equipment and lines are suddenly called, if the equipment and lines are in a short-circuit state, due to loose connection points and increased contact resistance, the large current caused by the sudden call cannot be quickly introduced into the ground, which will cause serious safety hazards such as equipment damage and casualties. as a result of
