Wind-vibration-resistant fixed suspension insulator string and working method thereof

Abstract

The invention relates to a wind-vibration-resistant fixed suspension insulator string. The wind-vibration-resistant fixed suspension insulator string is characterized in that the wind-vibration-resistant fixed suspension insulator string comprises a composite insulator and a suspension clamp; the composite insulator comprises a plurality of umbrella-shaped insulating blocks and a core rod for stringing the insulating blocks; a circular ring is fixedly arranged at the lower end of the core rod; the core rod is connected with the U-shaped ring of the suspension clamp through the circular ring; the suspension clamp comprises a clamp body; the clamp body comprises two clamping heads of which the tops are hinged with each other; semicircular grooves are formed in the middles of the two clampingheads and extend from the contact face of the two clamping heads to the interiors of the two clamping heads correspondingly; the two semi-circular grooves are combined to form a circular groove for mounting an insulated wire; the clamp body is installed in the U-shaped ring; the opening of the U-shaped ring faces downwards; and a first bolt at the lower end of the U-shaped ring is sequentially connected into the U-shaped ring and the clamp body in a screwed mode from the exterior of the U-shaped ring, and then penetrates out of the U-shaped ring to be fastened. The wind-vibration-resistant fixed suspension insulator string is simple in structure, and can effectively reduce the external abrasion of the insulated wire.

Description

technical field [0001] The invention relates to an anti-wind vibration fixed suspension insulator string and a working method thereof. Background technique [0002] The annual average wind speed and annual average number of windy days in coastal areas are significantly higher than those in inland areas, and the overhead lines of distribution networks are greatly affected by wind vibration. At present, the conductors on the straight poles of the overhead lines of the distribution network are usually fixed on the column insulators by binding wires or clamps. Due to the influence of wind load and conductor sag, the stress on the binding and fixing parts of the conductors is the largest. Under the action of wind force for a long time, the wires are prone to breeze vibration, which will lead to mechanical fatigue at the fixed part of the wire binding, causing damage to the wires at this part, and will eventually evolve into a serious accident of disconnection.
