Problems solved by technology

[0002] Insulators are a special insulation control that plays an important role in overhead transmission lines. However, the lightning strikes and pollution flashover problems of overhead insulated lines have always plagued the safe operation of electric power. Once struck by lightning, the power system will be paralyzed, which will cause huge Loss

Abstract

The invention discloses a lightning proof insulator which includes an umbrella skirt. The top part of the insulator is provided with an insulating cover which is arranged on a flange. The insulating cover is externally provided with an arc ignition rod. The flange is arranged on a porcelain body. The flange and the porcelain body are provided with a gasket therebetween. The flange is secured to the porcelain body through a cement adhesive. The surface of the porcelain body is provided with the umbrella skirt. The recessed surface under an umbrella of the umbrella skirt is provided with a deep umbrella rib structure. The insulating cover is externally provided with the arc ignition rod, and the bottom part is provided with an arc extinguishing ball, which guide the current in the lightning to the ground, thus providing a lightning proof function. The surface of the porcelain body is provided with the umbrella skirt, and the recessed surface under the umbrella of the umbrella skirt is provided with one circle or a plurality of circles of deep umbrella rib structures, which enable the insulator to have the advantages of strong humidity flashover, strong pollution flashover, and strong pollution resistance and effectively increase creep distance. Generally speaking, the insulator has the advantages of lightning prevention and pollution flashover prevention, integrated overall appearance, greater aesthetics, higher safety, and much convenience.

Description

technical field [0001] The invention relates to high-voltage electric porcelain power transmission equipment, in particular to a lightning protection insulator. Background technique [0002] Insulators are a special insulation control that plays an important role in overhead transmission lines. However, the lightning strikes and pollution flashover problems of overhead insulated lines have always plagued the safe operation of electric power. Once struck by lightning, the power system will be paralyzed, which will cause huge Loss. Contents of the invention [0003] The invention is a lightning protection insulator invented to solve the deficiencies of the prior art. [0004] Technical scheme of the present invention is as follows: [0005] A lightning protection insulator, comprising an umbrella skirt, an insulating cover is arranged on the top of the insulator, the insulating cover is arranged on a flange, an arc strike rod is arranged outside the insulating cover, and t...
