Rotary grounding wire clamp and using method thereof

Abstract

The invention provides a rotary grounding wire clamp and a using method thereof, which relate to the field of substation equipment overhaul. A cable containing groove is formed in the cambered surfaceof a semicircular pressing plate; the bottom of the semicircular pressing plate is connected with an operating rod in a lifting mode through a lead screw; the lead screw is sleeved with the operatingrod; a lead screw operating handle is arranged on the operating rod; a wire hook is rotatably installed on the semicircular pressing plate through a pin shaft; an operation rope connecting hole is formed in the end, away from the bent part, of the wire hook; the operation rope is connected with the wire hook; an adjusting hole is formed in the end, close to the operation rope connecting hole, ofthe wire hook and is of a gourd-shaped structure arranged in the extending direction of the vertical portion of the wire hook; and a pin shaft is arranged in the adjusting hole. When the wire is not hooked, the pin shaft is positioned at one end, close to the operation rope connecting hole, of the gourd-shaped structure; when the wire hook locks the wire, the pin shaft is located at the end, awayfrom the operation rope connecting hole, of the gourd-shaped structure. Thus, a safe distance between a constructor and a ground wire can be kept.

Description

technical field [0001] The invention belongs to the field of substation equipment maintenance, and in particular relates to a rotating ground clamp and a using method thereof. Background technique [0002] In actual work, it is impossible for maintenance personnel to hang the grounding wire on the wires outside the porcelain bottle string of the tension tower tower by using the grounding rod commonly used at present on the tension tower tower (except for the outer wire of the corner of the tension tower tower with a large rotation angle). [0003] Most of them will take the method of first hanging the two sets of grounding wires to the jumper of the strain tower, and then the maintenance personnel will use the insulation ladder or transfer from the porcelain bottle string to the wire end to the vicinity of the outer wire of the porcelain bottle string, and then connect 1 of the working phase wires. Remove the first ground wire and hang it on the wire, and then start the main...

AI Technical Summary

Problems solved by technology

Although the maintenance personnel did not touch the wires, they did not maintain a sufficient safe distance. In case of a sudden power call during the process, serious accidents will occur

[0004] When adjusting the angle of the existing grounding wire clamp, due to structural limitations, construction personnel need to directly adjust the angle of the wire hook, which shortens the safety distance and has certain potential safety hazards
