Turn buckle typed steplessly adjustable phase-to-phase spacer bracket

Abstract

The invention provides a turn buckle typed steplessly adjustable phase-to-phase spacer bracket. The bracket comprises an adjustable turn buckle body, an adjustable turn buckle screw rod I, an adjustable turn buckle screw rod II, an adjustable turn buckle fixing plate and a U-shaped ring, wherein the central line on a wider surface of the adjustable turn buckle body is provided with a slot for components to pass through along a length direction, and the two end points of the adjustable turn buckle body is provided with through holes along the length direction; one end of the adjustable turn buckle screw rod I passes through a through hole at one end of the adjustable turn buckle body, and one end of the adjustable turn buckle screw rod II passes through a through hole at the other end of the adjustable turn buckle body; the adjustable turn buckle screw rod I and the adjustable turn buckle screw rod II are fixed on the adjustable turn buckle body through the adjustable turn buckle fixing plate; and the other end of the adjustable turn buckle screw rod II is connected with the U-shaped ring. The adjustable phase-to-phase spacer bracket provided by the invention cooperates with a four bundle conductor spacer in a circuit swaying area to adjust proper installation length according to the phase interval of the installation positions of the phase-to-phase spacers; and the adjustable phase-to-phase spacer bracket is extremely flexible and the problem that a ball head is easy to fall off is solved.

Description

Technical field: [0001] The invention relates to an overhead power transmission line device, in particular to a turnbuckle screw type stepless adjustable interphase spacer rod support. Background technique [0002] During the operation of overhead transmission lines, various catastrophic accidents may occur, among which galloping is the more serious one. The harm caused by galloping is multifaceted. The light ones cause flashover and tripping, and the severe ones cause damage to hardware and insulators, broken strands and broken wires, loosening and detachment of tower bolts, and even tower collapse, resulting in major power grid accidents. With the development of China's power grid construction, transmission lines have characteristics and trends that are prone to galloping, such as large conductive cross-section, large number of splits, and compact structure, and the trend of line galloping prevention is more severe. Therefore, more and more anti-dance devices are used on ...

Problems solved by technology

However, there are still some disadvantages in this adjustable interphase spacer connecting fitting. First, the fitting can only be adjusted to several lengths, and the adjustment range is narrow. Secondly, most of the fittings are connected by ball joints, which are prone to balls during line operation. The head falls off, which affects the safety and stability of the line
