Description
Technical Field
The invention belongs to the field of transformer substation equipment maintenance, and particularly relates to a rotary grounding wire clamp and a using method thereof.
Background
In actual work, a maintenance worker cannot hang a grounding wire on a wire outside a tension tower porcelain insulator string (except for a wire outside a corner of a large-corner tension tower) on the tension tower by using a currently commonly used grounding rod.
Most of the grounding wires are hung on the jumper wires of the strain tower firstly, then the two grounding wires are transferred to the positions near the outer side wires of the porcelain insulator string by a maintainer with the help of an insulating ladder or the porcelain insulator string, then 1 grounding wire of the working phase wire is taken down and hung on the wires, and then the overhauling work is started. When the grounding wire is not hung on the external side wire of the porcelain insulator string, a maintainer takes down 1 grounding wire of the working phase wire after transferring to the wire and hangs the grounding wire on the wire, and violation behaviors exist in the process. Although the service personnel do not touch the wires, they do not maintain a sufficient safety distance, which can cause serious accidents in the event of a sudden call in the process.
When the existing grounding wire clamp is used for adjusting the angle, due to structural limitation, a constructor is required to directly adjust the angle of the wire hook, the safety distance is shortened, and certain potential safety hazards are caused.
