Abstract

The invention relates to a device for extra-high-voltage (EHV) transmission line operation, and in particular relates to a wire stroking device for repairing broken strands of EHV transmission lines. The device comprises an opening and closing motor, a fixed plate, a screw rod, a left nut, a left guide sleeve, a left guide rod, a left wire stroking device, a right guide rod, a right guide sleeve, a right wire stroking device and a right nut, wherein the opening and closing motor is installed outside the fixed plate; the screw rod connected with an output shaft of the opening and closing motor is arranged on the inner side of the fixed plate; the left nut and the right nut are in threaded connection with the screw rod; the left guide sleeve and the right guide sleeve are respectively installed on the left nut and the right nut rotatablely; one end of the left guide rod is connected with the left guide sleeve and the other end thereof is connected with the left wire stroking device; one end of the right guide rod is connected with the right guide sleeve and the other end thereof is connected with the right wire stroking device; and the left wire stroking device and the right wire stroking device are connected by a rotating shaft in a rotary manner. The device has a simple and effective wire stroking process, is low in line wear, has a small structure and light weight and can improve the personal safety, reduce the labor intensity of personnel and improve the efficiency.

Description

technical field [0001] The invention relates to a device for ultra-high-voltage transmission line operation, in particular to a line-stripping device for repairing broken strands of an ultra-high-voltage transmission line. Background technique [0002] Transmission lines are an extremely important part of power systems. Because the transmission line is under 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 light cases, or cause disconnect...
