Problems solved by technology

However, due to the low capacitance of the synthetic insulator itself to the ground, the distribution of the electric field strength at each part is extremely uneven during operation. Taking the 110KV product as an example, the highest electric field strength is 3-4 times the lowest electric field strength. As the voltage level increases, the difference in performance will be greater, and the outer sheath that has been working under a strong electric field for a long time will accelerate electrical corrosion and electrical aging, resulting in shortened life of composite insulators

Embodiment Construction

[0008] As shown in the accompanying drawings, the present invention includes an insulator. There is a semiconductor material layer 3 between the mandrel 1 and the outer sheath 2 of the insulator near the live end, and the semiconductor material layer 3 is electrically connected to the gold fitting 4 at the live end. The thickness of the semiconductor material layer 3 is 0.1-4mm, and the length is 50-1000mm. There is no gap between the semiconductor material layer 3 and the core rod 1 and the outer sheath material 2 .

Abstract

The invention is a voltage-equalizing synthetic insulator for high voltage power line, especially suitable for 10-1000 KV power line and including an insulator, where semiconductor material is applied in partial section of core rod and outer protective layer of the insulator near to electrified end and connected with armour clamp of the electrified end, and able to reduce difference in voltage distribution of the whole synthetic insulator and prolong the practical service life of the synthetic insulator.

Description

(1) Technical field [0001] The invention relates to a synthetic insulator for high-voltage transmission lines, which is especially suitable for use on 10-1000KV transmission lines. (two), background technology [0002] At present, synthetic insulators have been widely used on high-voltage transmission lines in my country. Because of its small size, light weight, and good anti-fouling flashover performance, it is favored by users. However, due to the low capacitance of the synthetic insulator itself to the ground, the distribution of the electric field strength at each part is extremely uneven during operation. Taking the 110KV product as an example, the highest electric field strength is 3-4 times the lowest electric field strength. As the voltage level increases, the difference in performance will be greater, and the outer sheath that has been working under a strong electric field for a long time will accelerate electrical corrosion and electrical aging, resulting in short...
