Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully and in 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] Such as figure 1 Shown is an embodiment of the lightning protection and ice protection insulator of the present invention. All components in this embodiment can be purchased in the market or processed in domestic manufacturing plants. It consists of two lightning arresters and a sub-insulator connected by connecting plate fittings 16 to form a Y-shaped overall structure. The sub-insulator is located at the lower end of the Y-shaped overall structure. The invention can realize the two-in-one function of lightning protection and anti-ice flashing, and is easy to meet the structural size requirements of the original tower window, does not affect the wind...

Abstract

The invention discloses a lightning-protective anti-icing insulator comprising two arrestors and an auxiliary insulator. The arrestors and the auxiliary insulator are connected through connecting plate fittings to form a Y-shaped integrated structure; the auxiliary insulator at the lower end of the Y-shaped integrated structure is provided with an arcing horn. The lightning-protective anti-icing insulator has both the lighting protection function and the icing flashover prevention function, the size requirements of original tower window structures are easily met, performances, such as wind fault and lightning protection, of a line are unaffected, insulation is unaffected after lightning discharging, insulating strength is high, the service life is long, the lightning-protective anti-icing insulator is simple to mount, changing the tower structure is not required, investment is saved, and maintenance cost is lowered.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to an 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 structure of comp...
