Embodiment Construction

[0024] The invention is applied to high-voltage transmission lines in the range of 110kV to 1000kV.

[0025] Such as figure 1 As shown, the present invention comprises upper and lower two spacer rods: an upper rod body 3 and a lower rod body 16, both of which are made of inner epoxy resin glass fiber reinforced plastic drawing rods and an outer silicon rubber composite material layer, and the upper rod body 3 and the outer side of the lower rod body 16 is an insulating shed 4, and the insulating shed 4 and the silicone rubber composite material layer are integrally constructed and formed as a whole.

[0026] An intermediate rod 14 is arranged between the upper rod body 3 and the lower rod body 16 . The two ends of the middle rod 14 are respectively provided with connecting structures matched with the lower end of the upper rod body 3 and the upper end of the lower rod body 16, and adopt movable connections. The connecting piece used in the connection structure in this embodi...

Abstract

The invention discloses a segmental combined type galloping-prevention composite phase-earth spacing rod which comprises an adjustable spacing rod body, an adjusting plate and a stay wire. The adjustable spacing rod body comprises an upper rod body, a lower rod body and a middle rod connected between the upper rod body and the lower rod body. The upper end of the upper rod body is connected with a connecting hardware fitting, the lower end of the lower rod body is connected with the adjusting plate, and insulation umbrella skirts are connected with the circumferences of the outer sides of the upper rod body and the lower rod body. The upper side of the insulation umbrella skirt of the upper rod body is connected with an end accessory, and the lower side of the insulation umbrella skirt of the lower rod body is also connected with an end accessory. The lower end of the upper rod body is connected with one end accessory and the upper end of the lower rod body is connected with one end accessory. The two ends of the stay wire are connected with the adjusting plate and the ground respectively. The segmental combined type galloping-prevention composite phase-earth spacing rod has the advantages of a phase-earth spacing rod, and can simultaneously restrain synchronous galloping and non-synchronous galloping of circuit wires.

Description

technical field [0001] The invention relates to the field of anti-dancing devices, in particular to a spacer bar. Background technique [0002] Overhead transmission lines undertake the important task of power transmission, and their safety is an important factor to ensure the safe operation of the power system. Judging from the statistical analysis data of overhead transmission line accidents in recent years, galloping has become one of the most important factors threatening line safety. Galloping can lead to various hazards, including line flashover, tripping, damage to hardware and insulators, broken strands and disconnected wires, and in severe cases, it will lead to the collapse of towers and major power grid accidents. [0003] Galloping is mainly caused by the wind acting on the wires, causing the distance between adjacent wires to be less than the minimum safe insulation distance under the operating voltage, resulting in breakdown of air insulation, thus causing pow...
