Abstract

The invention provides a splicing sleeve protective device which comprises transition rings and movable rings. The transition rings and the movable rings are sequentially and symmetrically arranged at the two ends of a sleeve. The sleeve, the transition rings and the movable rings are respectively formed by semicircular components arranged along the axis. The splicing sleeve protective device is characterized in that the sleeve is welded with the transition rings, the transition rings are movably connected with the movable rings, and the movable rings are movably connected. Compared with the prior art, the splicing sleeve protective device solves the problem of stress concentration of wires at the ends of the splicing sleeve protective device, meets the strength requirement, and is convenient to install.

Description

technical field [0001] The invention relates to a protection device, in particular to a protection device for a connecting pipe of a power transmission line. Background technique [0002] In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed rapidly, the operating voltage level of the power grid system has continued to increase, and the network scale has also continued to expand. At present, power grid construction has become the main direction of my country's electric power construction. By 2020, a strong smart grid will be fully built, and the goal of building a world-class power grid will be initially realized. [0003] At present, during the tension release construction of domestic transmission line wires, it is necessary to crimp multiple wires from different reels and connect them into a whole wire after being crimped through splicing tubes. Since the connecting pipe is a low-strength aluminum ma...
