Insulator

Abstract

The invention discloses an insulator. The insulator comprises an insulator body and a clamping device, wherein one end of the insulator is provided with a boss with regular polygonal section, and the clamping device is used for fixing leads and provided with a regular polygonal hole matched with the boss. The clamping device is sleeved with the boss via the regular polygonal hole and is fixedly connected with the boss by a fixing device. Since the connecting hole and the boss are regularly polygonal, the clamping device can be rotationally adjusted in many angles, mounting angle of the clamping device and the boss can be adjusted properly so as to fixedly mount the leads, and the mounted clamping device can be set in various angles so as to conform to different mounting conditions when the insulator is connected with the leads; by the rotatable design during mounting, material waste caused by setting too many clamping devices in order to ensure multi-angle adaptability of the insulator is avoided, the number of edges of a polygon can be increased to improve angle of the clamping device. In addition, the insulator is convenient to mount and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an insulator. Background technique [0002] In order to reduce the circuit reactance, the lines of modern high-voltage equipment are often erected with split wires, that is, each phase wire is composed of several sub-wires with smaller diameters, and each part of the wires is insulated and separated by insulation equipment. [0003] In the power transmission device of the power system, insulators are usually used to overhead the wires on the installation equipment. The insulator is a special insulation control, which has been developed from the insulation and isolation of the wires of the utility poles in the early days to the insulation connection of the 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...

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
