Tool for equipotential replacement of single-joint double-flexible bus tension insulator

Abstract

The invention, which relates to the technical field of electric power overhaul, provides a tool for equipotential replacement of a single-joint double-flexible bus tension insulator. A front clamping plate and a rear clamping plate are connected in an insulating pulling plate; a bracket is connected with the front clamping plate and the rear clamping plate respectively; a fixed connecting plate bayonet is arranged on the front clamping plate and U-shaped grooves for placing a right-angle hanging plate and a bolt are formed in the front clamping plate; and a vertical U-shaped clamp groove and a horizontal U-shaped clamp groove are formed in the rear clamping unit. A suspension loop string is fixed by a safety board assembly and a bufferfly nut. A lead screw assembly, a left rotating lead screw and a right rotating lead screw are connected with the insulating pulling plate. An insulating pulling plate locking pin fixes the insulating pulling plate; and the bracket is fastened by a bracket locking pin. Besides, a ball head pin is arranged at the front clamping plate; a marble, a spring, and a plug screw are used for localizing the ball head pin. The suspension loop string is formed by two suspension loops in series connection. According to the invention, the connecting plate, the right-angle hanging plate, and the double-flexible bus are connected and the suspension loops are connected with a portal at the other side based on a series connection structure, so that the provided tool is different from the existing ones in terms of appearance, functions, and application occasions; and the tool can be applied to replacement work of a single-joint double-flexible bus tension insulator on the equipotential condition. Moreover, the tool with a simple structure has high operability.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance, in particular to a tool for equipotentially replacing tension insulators of single-connected double flexible busbars. Background technique [0002] In the prior art, there are two types of tools for replacing single-connected tension insulators, namely, the tool for replacing tensile insulators used on substation bridge lines, and the tool for replacing single-connected tensile insulators on live lines used on 110kV transmission lines. Among them, the former cannot meet the conditions of equipotential operation, and the replacement of insulators must be completed when the equipment is powered off; while the latter can only carry out live maintenance on single-connected tensile insulators of 110kV transmission lines, and cannot replace insulators on double soft buses in substations. Moreover, neither of them can meet the field equipment conditions of single-connected double-flex...

AI Technical Summary

Problems solved by technology

Due to the insufficiency of the existing technology, the method of power outage inspection and maintenance of insulators is generally adopted in the power industry, and there is no precedent for implementing equipotential replacement of single-connected double flexible busbar insulators. The reason is the lack of corresponding insulator fixtures
