A kind of grounding wire operating rod universal conversion device

Abstract

Disclosed is a universal conversion device of a ground wire operating rod. The universal conversion device of the ground wire operating rod comprises a ground wire connecting body with one end being provided with a ground wire clamp bayonet, the ground wire connecting body arranged on the inner side of the ground wire clamp bayonet is provided with a ground wire clamp locking device in a sleeved mode, and the ground wire clamp locking device is internally provided with a spring mechanism and can move downwards in the axial direction. A universal steering device is arranged at the other end of the ground wire connecting body, and an operating rod bayonet and a ground wire clamp clamping and transmission device are both arranged on the outer side of the universal steering device. An anti-twisting transmission wire rope of the universal steering device penetrates through the middle of a universal steering steel ball, one end of the anti-twisting transmission wire rope is fixedly connected with the end, close to the ground wire clamp bayonet and the ground wire clamp locking device, of the conversion device, and the other end of the anti-twisting transmission wire rope is fixedly connected with one end of the operating rod bayonet. The universal steering steel ball is fixed at the end, close to the ground wire clamp clamping and transmission device, of the conversion device through a universal ball lock nut, and the universal steering steel ball can rotate in the area which is fixed by the universal ball lock nut. The universal conversion device of the ground wire operating rod has the advantages of being simple in structure, convenient to operate, high in reliability and working efficiency and the like.

Description

technical field [0001] The invention relates to a universal conversion device for a ground wire operating rod, which belongs to the field of electric equipment tools. Background technique [0002] In the power system, when some electrical equipment in the substation, such as capacitor banks, busbar bridges, grounding transformers, etc., need power-off maintenance, in order to ensure the safety of the maintenance test staff and equipment, any incoming side of the power-off maintenance equipment must be Hang the grounding wire to prevent sudden calls from endangering the safety of test personnel and equipment. At present, the grounding wires in the substations are all installed using a special grounding wire operating rod to complete the installation of the grounding wires, and the capacitor banks and grounding substations in the substation are all closed equipment, and their surroundings are closed. Use net doors or baffles to enclose live equipment to ensure safety. When t...

AI Technical Summary

Problems solved by technology

When the grounding wire needs to be hung, the method of opening the net door after a power failure and allowing the operator to use the grounding wire operating lever to hang the grounding wire is adopted. When setting the grounding wire, the grounding wire operation stick cannot be used normally to hang the grounding wire safely and reliably or the grounding wire cannot be hung at all; The restrictions on the structure and installation location of new equipment will also cause the above situation to occur

However, when the equipment is powered off for maintenance, the operation of the grounding wire is not standardized, and the grounding wire is unreliable. There are huge hidden dangers to the operation, the safety of the maintenance personnel and the safety of the equipment.
