Problems solved by technology

The decrease of the umbrella spacing can increase the creepage distance of the polymer insulator under the condition of a certain insulation height, but the pollution flashover voltage does not increase linearly with the increase of the creepage distance, and the umbrella spacing is too small, especially for the prismatic Protruding bell-shaped products are prone to bridging between umbrellas, and the utilization rate of creepage distance is relatively reduced
[0005] Polymer insulators operate in a wide geographical range, and different regions have their own geographical particularities, resulting in complex operating conditions. At the same time, there are external uncertainties in the transportation, installation and maintenance of polymer insulators, which affect the safe operation of polymer insulators.

Description

technical field [0001] The invention relates to a composite insulator, in particular to a polymer disk-shaped insulator for a disk-shaped suspension insulator string element and a preparation method thereof. Background technique [0002] Polymer insulators are favored by the industry because of their great advantages over porcelain and glass insulators in terms of weight, zero measurement value, pollution flashover voltage resistance, and no self-explosion, especially the high pollution flashover voltage. The study found that there is a certain relationship between the shed structure of the insulator and the pollution flashover voltage, so that the pollution flashover voltage of polymer insulators with the same other conditions but different shed structures is different. [0003] The influence of the umbrella diameter on the pollution flashover characteristics of polymer insulators is as follows: the increase of the umbrella diameter increases the equivalent diameter of the ...
