Problems solved by technology

[0004] The technical problem to be solved by the present invention is to solve the shortcomings of existing composite insulators, such as the poor lightning protection performance and the inability of line arresters to undertake the function of line insulators. Sectional discharge is also easy to damage the surface insulation performance of insulators, and the increase in length affects the wind deflection and lightning protection performance of the line. A two-in-one that can realize lightning protection and anti-ice flashing functions is proposed, and it is easy to meet the structural size requirements of the original tower window , does not affect the wind deflection, lightning protection and other performance of the line, does not affect the insulation performance after lightning discharge, the insulator has high dielectric strength and long life, only one hanging point on the tower, easy installation, no need to change the structure of the tower, thus saving investment, Composite insulator for lightning protection and anti-ice flashing with reduced maintenance cost

Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and preferred embodiments, but the protection scope of the present invention is not limited to the following specific embodiments.

[0026] figure 1 Shown is an embodiment of the lightning protection and anti-icing flash composite insulator of the present invention. All components in this embodiment can be purchased in the market or processed in domestic manufacturing plants. It is an inverted Y-shaped overall structure formed by connecting a lightning arrester and two sub-insulators through connecting plate fittings 16. The two sub-insulators are located at the lower end of the inverted Y-shaped overall structure, and arcing angles 17 are set on both sub-insulators. The invention can realize the two-in-one function of lightning protection and anti-icing flash, and is easy to meet the structural s...

Abstract

The present invention disclosed a lightning -proof ice -proof and compound insulation, including a minefarers and two branches insulators. The minefarers and the insulator were connected to a pour -type Y -type overall structure through the continuous gold gear.The arc angle is set on the insulator.The present invention can achieve two -in -one lightning protection and ice -resistant function, and it is easy to meet the requirements of the structure size of the original tower window.High and long life, only one hanging point on the pole tower, easy to install, does not need to change the tower structure, thereby saving investment and reducing maintenance costs.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a composite insulator with the function of lightning protection and ice flash protection, which is suitable for high-voltage transmission lines in areas prone to ice disasters and thunderstorms. Background technique [0002] In recent years, with the rapid development of my country's social economy and power construction, more high-voltage transmission lines have been erected in some alpine mountainous areas with complex terrain and cold climate. In these areas with special geographical environment, when there is severe weather, the transmission line is prone to icing flashover or lightning flashover and trip accidents, which seriously affect the safe and stable operation of transmission line power transmission and power grid. [0003] At present, for icing flashover, there are methods of increasing umbrella diameter and spacing, and enriching the umbrella structur...
