Insulating creepage increasing cap additionally installed on electric suspension type insulator

Abstract

The invention relates to an insulating creepage increasing cap additionally installed on an electric suspension type insulator, which comprises a suspension type insulator with a metal cap. The creepage increasing cap is characterized by being fixed on the metal cap of the electric suspension type insulator; and the creepage increasing cap is in a hollow cylindrical shape, and the top is provided with a creepage increasing edge. The invention has the advantages of increasing the external insulating creepage distance of the suspension type insulator and improving an insulating value and a pollution flashover voltage value; the dryness of the insulator in the damp and hot environment is reinforced, and thus the insulating level is improved, and the pollution flashover voltage value is improved; because the product is additionally installed on the metal cap of the insulator, the important failure self-explosion display function of the glass insulator is not influenced; and the pollution flashover voltage value of the suspension type insulator can be improved by more than 1.5 times.

Description

technical field [0001] The invention belongs to external insulation equipment for power transmission and transformation, in particular to an insulation climbing cap added to a power suspension insulator in the external insulation equipment for power transmission and transformation. Background technique [0002] Power suspension insulators are products widely used in power transmission and transformation, and external insulation of power grids. Its function is to ensure the safe operation of the insulation outside the grid. Its important functional index is its anti-pollution flashover voltage value. The material of power suspension insulators is generally porcelain or glass. At present, this product has the following important technical problems: the anti-pollution flashover voltage value is low; some insulators made of glass are retrofitted with additional climbing products, which affects the self-explosion function of the glass insulator. The self-explosion function of t...

Problems solved by technology

At present, this product has the following important technical problems: the anti-pollution flashover voltage value is low; some insulators made of glass are retrofitted with additional climbing products, which affects the self-explosion function of the glass insulator. The self-explosion function of the shed of the glass insulator is a suspension insulator After the insulation is lost, it becomes the display function of the fault zero value, which can automatically and timely display the fault of the insulator product, thereby avoiding the accident of the power grid and ensuring the safe operation of the power grid
