Abstract

The embodiment of the invention discloses an ultrahigh pressure transmission line broken strand stroke-back device and a using method thereof. The ultrahigh pressure transmission line broken strand stroke-back device comprises a base, a cohesion device, a support outer ring, a rotating inner ring and a guide closed plug, wherein the base is fixedly provided with a lead screw, the cohesion device is movably connected on the lead screw, the support outer ring is fixed on the tail end of the cohesion device, the rotating inner ring is fixed in the support outer ring, and the guide closed plug and the rotating inner ring are movably connected. The base is connected with a power driving unit, and is used to achieve to drive the lead screw, thereby driving the cohesion device to move. The cohesion device drives the support outer ring to move, the rotating inner ring is driven through the support outer ring to walk along a ground wire, a stroke wire top column which is arranged in the rotating inner ring spirally moves, broken wires are stroked back, and the whole stroke back process of wires can complete in short time, and is simple in operation, thereby improving stroke back efficiency of transmission lines.

Description

technical field [0001] The invention relates to the technical field of power transmission line repair, in particular to a device for pulling back a broken strand of an ultra-high voltage power transmission line and a method for using the same. Background technique [0002] The transmission line is an extremely important part of the power system. Because the transmission line has been in the open air for a long time, the operating environment is very poor, and it is affected by various natural conditions. Under the long-term action of various stresses, transmission lines will cause material brittleness, and lightning flashover and external force damage will also cause damage to the surface of the conductors; especially the transmission lines in coastal and industrial areas are more likely to be corroded, resulting in transmission lines. Defects such as cracks and broken strands. The damage and broken strands of overhead lines will reduce the current carrying capacity in ligh...
