Abstract

The invention provides a swinging preventing device for a power transmission line. The swinging preventing device comprises a connecting rod, a first connecting assembly, a composite insulator, a second connecting assembly and two spacers used for being connected with the power transmission line, wherein the two spacers are connected through the connecting rod; a first end of the composite insulator is connected with the connecting rod through the first connecting assembly; and a second end of the composite insulator is connected with the ground through the second connecting assembly. According to the invention, the spacers are enabled to be connected to the ground through the first connecting assembly, the second connecting assembly and the composite insulator, and thus a downward pulling force is applied to the spacers so as to increase the stability of the spacers, so that a swinging preventing effect of the power transmission line is enhanced, and the stability of the power transmission line is improved. In addition, the spacers are isolated from the ground through setting the insulator, thereby preventing breakdown, forming a loop with the ground, and improving the safety of the swinging preventing device.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to an anti-galling device for transmission lines. Background technique [0002] In my country's power grid meteorological disasters, the ice-covered galloping of overhead conductors is a form of natural disasters with high frequency, wide range of influence, and large losses. With the rapid development of my country's power grid scale and the frequent occurrence of severe weather, since the beginning of the new century, the frequency of galloping accidents in the power grid has increased significantly, and the degree of harm has increased significantly. Large-scale galloping accidents have occurred almost every year, causing serious economic damage. loss and social impact. [0003] At present, spacers are mainly used to support the sub-conductors in the transmission lines of our country. When in use, the spacers are installed between the sub-conductors of the transmission line...
