Abstract

The invention relates to a universal adapter connector for hot-line work, which comprises an upper connecting plate (1) and a lower connecting plate (4), and is characterized in that the upper connecting plate and the lower connecting plate are connected through a bolt section (2) of the upper connecting plate and a nut section (3) connected on the lower connecting plate in a screw-thread fit manner, the bolt section (2) is provided with a small screw hole M (7), the nut section (3) is provided with a small screw hole N (7), and the bolt section (2) and the nut section (3) are screwed to a certain position so as to enable the small screw hole M (7) and the small screw hole N (7) to form superposition. The beneficial effects are that the universal adapter connector provided by the invention can solve problems that a 220kV linear insulator string live replacement tool is unsatisfactory in stress and easy to be damaged, working tools are difficult to be installed, the labor intensity of operators is great, and even live replacement cannot be carried out, the work efficiency is greatly improved, an operation risk value is enabled to be reduced, the universal adapter connector is safe, reliable and time and labor saving, and the maintenance work for power transmission line linear insulator string replacement is enabled to be more standardized and more normalized.

Description

technical field [0001] The invention belongs to the electric power industry, and belongs to the technical field of a special tool structure for replacing a whole string of 220kV linear insulators with electricity. Background technique [0002] At present, the tools and appliances used for live replacement of 220kV linear insulator strings are all designed and manufactured according to the ideal angle of 90° between the cross arm of the tower and the conductor, but the angle between the cross arm and the conductor in the actual operating equipment is not a standard right angle. There is a certain angle difference. During the operation process, the force on the tools is not ideal, easy to damage, difficult to install the operating tools, increase the labor intensity of the operators, and even cannot be replaced while live, and can only be forced to cut off the power line for maintenance, which increases the risk of operation and increases the power outage time of the equipment...
