Abstract

The invention relates to electric power protection equipment. The invention relates to an overhead transmission line galloping suppression device. The device comprises a wire, a supporting rod, a pulley assembly, a counterweight, a composite insulator, a main insulating rope and a load-bearing insulating rope; and the supporting rod is obliquely buried on the ground, fixed pulley arranged above movable pulley, the fixed pulley is connected to the supporting rod, the main insulating rope is wound on the wire, two ends of the main insulating rope are respectively connected with two composite insulators, one end of the load-bearing insulating rope is connected to the upper end of the movable pulley, and the other end of the load-bearing insulating rope is connected to the lower end of one ofthe composite insulators after passing around the fixed pulley and the movable pulley in turn, and the counterweight is connected to the lower end of the movable pulley. The overhead transmission linegalloping suppression device has the advantages of flexible and reliable use and reasonable design, galloping of lines can be inhibited by the aid of pulling modes, and safe operation of power transmission lines can be guaranteed. Moreover, no pulling devices need to be arranged at the two ends of the line, and the line can be pulled at any position of the power transmission line.

Description

technical field

[0001] The invention relates to electric power protection equipment, in particular to an overhead power transmission line galloping suppression device. Background technique

[0002] Overhead power lines are exposed to the wild all year round, and are seriously affected by geographical location and environmental conditions. They are prone to icing or strong winds that cause conductors to dance. Large, it is easy to cause the line to dance and endanger the safe operation of the line.

[0003] The existing technology often adopts the method of setting a heavy object pulling mechanism at both ends of the wire to increase the tension of the wire to suppress the sagging and galloping of the wire, but the length of the power line is generally large, and the use of the existing technology to install a heavy object pulling mechanism at both ends of the wire appears. is not enforceable. Contents of the invention

[0004] The object of the present invention is to pr...
