an insulator

Abstract

The invention discloses an insulator. The insulator comprises an insulator body, one end of the insulator body is fixedly connected with one end of a round rod which is arranged in a through hole of a set of wire clamping plates in a sleeved manner, a fixing unit for tightly clamping the wire clamping plates and the insulator body is arranged on the round rod, and clamping units for clamping the set of wire clamping plates are arranged on the wire clamping plates. The insulator has the advantages that the wire clamping plates at the end of the insulator can rotate by different angles before being fixed, so that the insulator is enable to adapt to wire connection in multiple directions, and arrangement of multiple insulators for different wire connections is avoided; by means of adopting the fixing unit to fix, reliability in connection is guaranteed, cost is reduced, and working efficiency in wire connection is improved; wires are fixed by a distance-adjustable clamping structure, so that the insulator is enabled to be applicable to wires in different specifications, usage range is wider, and mounting is simpler.

Description

Technical field [0001] The invention relates to the technical field of power equipment, in particular to an insulator. Background technique [0002] In order to reduce the reactance of the circuit, the lines of modern high-voltage equipment are often erected with split conductors, that is, each phase conductor is composed of several sub-conductors with smaller diameters, and each part of the conductor is insulated and separated by insulating equipment. [0003] In the power transmission device of the power system, insulators are usually used to overhead the wires on the installation equipment. Insulators are a special kind of insulation control. From the early period of insulating and blocking the wires of the poles, it has developed to the insulated connection of high-voltage equipment lines. [0004] In the prior art, single-phase double-split wires are usually connected by two insulators. Although the wires are insulated and isolated, the disadvantage is that the one-to-one arran...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, single-phase double-split wires are usually connected by two insulators. Although the wires are insulated and isolated, the disadvantage is that the one-to-one arrangement of wires and insulators makes the number of insulators too large and increases equipment costs. , and the power equipment is too bloated

There is also a method of adding a ring clamp body at the end slot of the insulator. By putting the wires into the clamp body and the wire slot, and using bolts to fasten the wires, this method solves the problem of fixing the end of the insulator. However, with the development and progress of transmission lines, the requirements for the transmission capacity of wires are gradually increasing, and the types of wires are also increasing, and they have been expanded in the existing models, while the size of the original trunking remains unchanged. As a result, the wire model does not match the size of the wire slot, which affects the fixing of the wire
