Fixing device for air lead

Abstract

The invention relates to an overhead wire fixing device, which comprises an angular lower base plate composed of two semi-rings, an upper press plate, and bolts, wherein the two ends of each semi-ring are respectively provided with a projecting lug, a bolt hole for connecting the bolt is provided on each projecting lug, and the two ends of the upper press plate are respectively provided with a through-hole corresponding to the bolt hole on the projecting lug of the semi-ring and passing through the bolt. By using the device, the overhead wire can be directly and conveniently fixed on the insulator, instead of the original fixation mode by a metal binding wire. The inventive device has the advantages of simple installation, low labor intensity, exemption from inspection and maintenance during operation, excellent burn-out proof performance, safe operation, and high reliability; and is suitable for being used on the copper and aluminum overhead wire with 10 KV.

Description

Technical field [0001] The invention relates to an overhead conductor fixing device used for an overhead distribution line of an electric power system, and belongs to the technical field of electric power distribution network. Background technique [0002] The wires and insulators of 10kV overhead distribution lines are generally bound and fixed by metal ties. It has three major shortcomings: (1) troublesome operation and high labor intensity of workers; (2) low binding strength, and the degree of binding of each worker varies greatly; (3) poor safety. Once a single-phase short-circuit occurs between the wire and the earth or a phase-to-phase short-circuit occurs between the wire and the wire, the arc is likely to burn the metal wire, so that the wire is in an unsafe state without being fixed to the insulator, which constitutes a huge impact on the safe operation of the system Threats, and the burning of metal ties is often not easy to detect. How to improve the fixed pattern bet...

It has three major disadvantages: (1) troublesome operation and high labor intensity for workers; (2) low binding strength, and the degree of binding of each worker varies greatly; (3) poor safety

Once a single-phase short circuit occurs between the conductor and the ground or a phase-to-phase short circuit occurs between the conductor and the conductor, the arc is likely to burn the metal tie wire, so that the conductor is in an unsafe state without being fixed with the insulator, which poses a huge threat to the safe operation of the system. Threat, and the situation where the metal wire is blown is often not easy to find
