Suspension clamp for gap type heatproof capacity-improving conducting wires

Abstract

The invention relates to a suspension clamp for gap type heatproof capacity-improving conducting wires, relating to the technical field of electrical power hardware for transmission equipment and substation equipment. The suspension clamp comprises heatproof preformed armor rods and a clamp body, wherein a wire chase is arranged in the clamp body; the clamp body is provided with two hanging plates; the two hanging plates are respectively fixed on both sides of the clamp body through pins, the upper ends of the two hanging plates are connected with lock pins through bolts and nuts; a treadle bar is arranged in the wire chase, both ends of the treadle bar are respectively arranged in the clamp body through U-shaped bolts, the cross section of the inner side of the treadle bar is a cambered surface, and the central longitudinal section of the wire chase is provided with a cambered surface; and a suspension angle of the clamp is from 25 to 30 degrees. The holding power of hardware to conducting wires is increased because of the cambered surfaces of the central parts of the treadle bar and the wire chase, the requirements on line operation are met, and the special requirements on the holding power of a clamp steel core during the application of the gap type conducting wires is met. The suspension angle of the clamp is from 25 to 30 degrees so that the universality of the clamp is stronger and the applicable temperature change is large. The invention can satisfy suspension change large, and the edges of both ends of the clamp cannot damage the conducting wires.

Description

technical field [0001] The invention relates to the technical field of electric power fittings used for power transmission and transformation equipment. Background technique [0002] Domestic gap-type heat-resistant capacity expansion wires have begun to be used, but the matching high-temperature wire fittings are still in the development stage. There is also no recognized mature product suitable for the suspension clamp for gap-type heat-resistant capacity-enhancing wires. [0003] The existing suspension clamps usually use the U-shaped wire groove of the wire clamp to hang or support the wires, and the wires are directly arranged in the U-shaped wire grooves. The suspension wire clamps of this structure are easy to damage the wires, and the temperature changes greatly. In the case of unsafe conditions, the stability of the grip on the wire cannot be maintained, the stress on the wire is concentrated, and the heat dissipation effect of the wire is poor. When the wire runs...

[0003] The existing suspension clamps usually use the U-shaped wire groove of the wire clamp to hang or support the wires, and the wires are directly arranged in the U-shaped wire grooves. The suspension wire clamps of this structure are easy to damage the wires, and the temperature changes greatly. In the case of the wire, the stability of the holding force of the wire cannot be maintained, the stress of the wire is concentrated, and the heat dissipation effect of the wire is poor

When the wire runs at high temperature, it may have adverse effects on accessories such as insulators
