High-cold-resistance porcelain insulator and manufacturing process thereof

Abstract

The invention discloses a high-cold-resistance porcelain insulator and a manufacturing process thereof. The high-cold-resistance porcelain insulator comprises a porcelain umbrella group, a first shellis installed at the top of the porcelain umbrella group, two second shells are welded to the two sides of the first shell, one side of each second shell communicates with the first shell, and a thirdshell is installed at the bottom of the porcelain umbrella group. A steel foot bolt is installed on one side of the second fixing plate, and one side of the steel foot bolt is sleeved with a gasket.By arranging a second sliding block to slide in a second sliding rail, an arc-shaped plate can be connected with a heat insulation plate and a sponge block to be disassembled together only by rotatinga first bolt and a second bolt, and maintenance work of workers is facilitated. When the porcelain insulator is used, the sponge block is arranged to protect the surface of the porcelain umbrella group, the contact area between the surface of the porcelain umbrella group and the external temperature is reduced, the influence of the external temperature on the porcelain umbrella group is reduced,and the heat insulation plate is arranged to insulate the temperature of the porcelain umbrella group to assist cold-resistant protection of the porcelain umbrella group.

Description

technical field [0001] The invention relates to the technical field of electric power engineering auxiliary equipment, in particular to a high cold resistance porcelain insulator and a manufacturing process thereof. Background technique [0002] Insulators are devices installed between conductors at different potentials or between conductors and grounding components that can withstand voltage and mechanical stress. There are many types of insulators with different shapes. Although the structures and shapes of different types of insulators are quite different, they are all It is composed of insulators and connecting fittings. Insulators are a special insulation control that can play an important role in overhead transmission lines. Insulators were mostly used for utility poles in the early years, and gradually developed in high-voltage wire connections. There are many disk-shaped insulators hung on one end of the tower. It is to increase the creepage distance. It is usually m...

AI Technical Summary

Problems solved by technology

[0003] Porcelain insulators are the most commonly used insulators. During their use, the surface is usually coated with waterproof paint. Poor results in cracking of the surface coating of porcelain insulators, affecting its normal use. Existing solutions generally add heat insulating materials to the surface, but the heat insulating materials are fixed on the surface of porcelain insulators, making it inconvenient to disassemble them during maintenance. For this reason, Propose a high cold resistance porcelain insulator and its manufacturing process
