Problems solved by technology

However, in the windy area, the shed shed of the product is affected by the huge wind force, and the shed shed will swing violently. The consequence is: the root of the shed shed is stressed and swings frequently, causing the root to tear in a short period of time; The large umbrella swings violently and collides with the adjacent sheds, causing the sheds to wear and due to the bridging of the sheds, the effective creeping distance of the product is rapidly reduced

Embodiment 1

[0019] The invention provides an arrangement structure of equal-diameter sheds for wind-resistant composite insulators. The sheds 2 are arranged on the periphery of the rod body 1, and the cross section of the sheds 2 is connected to the rod body 1 from the root of the shed 3 to the top 4 of the shed, which is composed of a gradient structure from large to small, which is suitable for the wind load. , to fully reduce the bending deformation of the shed 2. The diameter of the sheds is 85mm, and the distance between the tops of two adjacent sheds is 58mm.

[0020] Attached below figure 2 The arrangement structure of shed sheds with large and small diameters for a wind-resistant composite insulator of the present invention will be further described.

Embodiment 2

[0022] The invention discloses a shed shed arrangement structure of large and small diameters for a wind-resistant composite insulator, which is composed of a rod body 1 and a shed 2. The shed 2 is designed to be open, and the strength of the root 3 of the shed is improved. The sheds 2 are arranged on the periphery of the rod body 1, and the cross section of the sheds 2 is connected to the rod body 1 from the root of the shed 3 to the top 4 of the shed, which is composed of a gradient structure from large to small, which is suitable for the wind load. , to fully reduce the bending deformation of the shed 2. The diameter of the large shed is 200 mm, the diameter of the small shed is 170 mm, and the distance between the tops of two adjacent sheds is 43 mm.

Abstract

The invention relates to a wind-resistant composite insulator, which consists of a bar body and umbrella skirts. Open umbrella skirts are designed, and the root strength of the umbrella skirts is improved. The umbrella skirts are arranged on the periphery of the bar body, and a gradient structure which becomes smaller and smaller from the roots of the umbrella skirts to the tops of the umbrella skirts is used for connecting the sections of the umbrella skirts with the bar body, so that adaptation to borne wind power load is realized, and bending deformation of the umbrella skirts is reduced fully. The umbrella skirts are arranged in an equal-diameter way and an unequal-diameter way. The wind-resistant composite insulator has the advantages of high wind resistance, realization of an anti-ageing and good outer insulating structure under the severe environmental condition of strong wind, prevention of reducing the effective creepage distance of a product, freeness from cleaning and maintaining, long service life, guarantee of safe running of a power system, and remarkable economic benefit and social benefit.

Description

technical field [0001] The invention relates to a wind-resistant composite insulator, which belongs to the technical field of power transmission component manufacturing. Background technique [0002] Suspension composite insulator products at home and abroad are generally designed with a shed with a certain downtilt structure. The main consideration is to increase the creepage distance and maintain a certain dry area under the rain to improve the electrical performance of the product. However, in the windy area, the shed shed of the product is affected by the huge wind force, and the shed shed will swing violently. The consequence is: the root of the shed shed is stressed and swings frequently, causing the root to tear in a short period of time; The large umbrella swings violently and collides with the adjacent sheds, causing the sheds to be worn and due to the bridging of the sheds, the effective creepage of the product is rapidly reduced. The utility model adopts an open ...
