Determination method of aging degree based on pulverization classification of composite insulators

Abstract

The invention discloses a method for determining the aging degree based on the pulverization classification of composite insulators, which extracts the pulverization area of ​​the upper surface shed of the composite insulator, and divides the pulverization degree of the composite insulator according to the pulverization area of ​​the upper surface of the composite insulator shed. Finally, the aging degree of the composite insulator is determined based on the pulverization level of the composite insulator. The method for determining the aging degree of composite insulators provided by the present invention is simple in process, and the aging degree of composite insulators can be determined simply by dividing the pulverization level by pulverization area, which can provide an accurate description of the state quantity for the evaluation of composite insulators, and the operation status of composite insulators provide an important basis for research.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, in particular to a method for determining the aging degree based on the pulverization and classification of composite insulators. Background technique [0002] Composite insulators are widely used in overhead transmission lines in my country, and their degradation cannot be ignored. Pulverization is one of the manifestations of composite insulator degradation. The so-called pulverization refers to the appearance of tiny powdery particles different from the original silicone rubber on the surface of the shed of the composite insulator. Pulverization is an external manifestation of the aging of silicone rubber materials in composite insulators. The degree of pulverization is closely related to the aging degree of silicone rubber. The current technology describes the surface pulverization of composite insulators in a general way. As a result, it is impossible to know the degree o...

Problems solved by technology

Pulverization is an external manifestation of the aging of silicone rubber materials in composite insulators. The degree of pulverization is closely related to the aging degree of silicone rubber. The current technology describes the surface pulverization of composite insulators in a general way. As a result, it is impossible to know the degree of pulverization of the pulverized composite insulator based on the visual inspection of the report as "powdering", and it is difficult to judge the degree of aging by "powdering".
