Abstract

The invention discloses a novel long rod type porcelain composite insulator. The long rod type porcelain composite insulator comprises an insulator body, wherein an outer insulating umbrella skirt sheath is arranged outside the insulator body; hardware fittings are cemented at two ends of the body; a mounting inner hole of each hardware fitting is in a sawtooth shape; and the outlet end of each hardware fitting is in a circular arc shape, and a rectangular groove is formed outside the outlet end. Due to the adoption of reasonable structural design and high-quality production raw materials and the selection of an advanced manufacturing process, the long rod type porcelain composite insulator has high electromechanical properties. According to the long rod type porcelain composite insulator, high-temperature vulcanized silicon rubber is used as the outer insulating umbrella skirt sheath, high-strength ceramic is used as internal insulation, and the end fittings are cemented by using high-strength silicates through a amplitude varying process to manufacture the porcelain composite insulator. By the porcelain composite insulator, the accidents of brittle failure and string breakage can be avoided, and the problem of external insulation pollution flashover of the porcelain insulator is solved, so that the long rod type porcelain composite insulator is high in mechanical and electrical properties and is suitable for various extremely severe work conditions.

Description

technical field [0001] The invention relates to a long rod-shaped porcelain composite insulator for extra-high voltage transmission lines, and mainly invents a long rod-shaped porcelain composite insulator with excellent mechanical and electrical properties and a manufacturing method thereof. Background technique [0002] High-voltage insulators are widely used in power systems, among which high-voltage line insulators are used the most. In recent years, the number of insulator string components used on high-voltage transmission lines ranges from tens of thousands to several million, all of which are required to ensure good long-term operating performance. If the performance of the insulator is poor for a long time, the power will be cut off continuously due to the continuous damage and maintenance of the insulator, so that the line cannot operate normally. [0003] In recent years, my country's electric power construction and transmission projects, AC and DC UHV transmissi...
