a power insulator

Abstract

The invention relates to a power insulator, which includes a fixing seat, left fittings, right fittings, middle fittings, clamping device, adjusting device and supporting device, and the damage can be achieved by rotating the clamping rods on the front and rear sides of the damaged insulator. The fittings below the insulators are disassembled to facilitate subsequent disassembly of the insulators. When adjusting the distance between the various yokes, turn the bumps to increase the distance between the yokes above each extension plate and pull the telescopic plate Long, the first locking rod and the second locking rod at both ends of the external support rod are snapped into the fixed grooves on both sides of the telescopic plate, and the two sliding blocks are moved to correspond to the two ends of the hardware to be removed, and then the two supporting The brackets respectively hang the telescopic rods and fittings connected to the two ends of the fittings to be disassembled, which is convenient for supporting the telescopic rods and fittings connected to the fittings to be removed. By turning the tightening handle, the rotation of the tightening handle drives the moving circular plate to rotate forward. The tension on the cable is fixed.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to a power insulator. Background technique [0002] An insulator is a special insulation control that can play an important role in overhead transmission lines. Insulators were mostly used on utility poles in the early years, and gradually developed in the high-voltage wire connection tower. Many disc-shaped insulators are hung at one end of the tower. It is In order to increase the creepage distance, usually made of glass or ceramics, it is called an insulator, a device that can withstand voltage and mechanical stress installed between conductors of different potentials or conductors and grounding members. There are many types of insulators in different shapes. Although the structure and shape of different types of insulators are quite different, they are all composed of two parts: insulators and connecting fittings. The insulators will be damaged during long-term use, so the i...

AI Technical Summary

Problems solved by technology

[0004] (1) Since the insulator will be damaged during use, the existing device needs to remove the entire insulator and fittings when taking out the damaged insulator during use, which is not convenient for operation;

[0005] (2) When removing the middle insulator, the fittings on both sides cannot be supported, so it is necessary to support the fittings when disassembling,

[0006] (3) When the existing insulator fixes the cable, it is impossible to adjust the tightness of the long-term used cable
