Description
Technical Field
The invention relates to the technical field of power distribution networks, in particular to an overhead ground wire fitting displacement reset device.
Background
The high-voltage overhead line has high pole position and large span, and can vibrate when the wire is acted by wind. The working conditions at the wire suspension are most unfavourable when the wire vibrates. Due to multiple vibrations, fatigue failure of the wire may occur due to periodic bending. When the span of the overhead line is more than 120 meters, a damper is generally adopted to prevent vibration. The damper is used for reducing the vibration of the wire caused by wind force.
On a high-voltage overhead line, a small hammer is usually hung on a wire close to two sides of an insulator, and the small hammer is called a damper and is arranged for reducing the vibration of the wire due to wind power. The high-voltage overhead line has high pole position and large span, and can vibrate when the wire is acted by wind. The working conditions at the wire suspension are most unfavourable when the wire vibrates. Due to multiple vibrations, fatigue failure of the wire may occur due to periodic bending. When the span of the overhead line is more than 120 meters, a damper is generally adopted to resist shock. For steel core aluminum wire, the weight of the damper is w =0.4d-2.2 (kg), wherein d is the outer diameter (millimeter) of the wire, and the damper consists of a weight with certain mass, a zinc steel stranded wire with higher elasticity and high strength and a wire clamp.
Hazards of the stockbridge damper after the displacement on the overhead ground wire: 1. the shockproof effect is lost and the ground wire is worn. The hardware loses the shock resistance after running, causes repeated vibration fatigue damage of the ground wire, and causes strand breakage, wire breakage and tower collapse, and meanwhile, the ground wire is abraded due to looseness of the hardware body. 2. After the hardware fitting runs, the hardware fitting loosens and possibly falls from high altitude to cause casualties. An energy-saving fitting weighs about 4 kilograms and is generally more than 30 meters away from the ground, and once pedestrians and vehicles pass through the lower part of the fitting after running, the result is unimaginable.
