Description
Technical field
The invention belongs to electric power project engineering field more particularly to a kind of aging journeys based on composite insulator powdering grading
Spend the method for determination.
Background technique
Composite insulator is widely applied in China's overhead transmission line, and deterioration problem can not be ignored, and dusting is compound exhausted
One of the form of expression of edge deterioration.So-called dusting refers to that composite insulator umbrella skirt surface occurs different from the micro- of former silicon rubber
Small powdery particulate matter.Dusting is the external manifestation of composite insulator silicon rubber material aging, dusting degree and silicon rubber aging journey
Spend it is closely related, current techniques for surface of composite insulator dusting describe more general, either slight dusting or severe
Dusting is characterized with dusting, is caused only with reporting that upper visual examination is that " dusting " can not know the dusting composite insulator
Dusting degree, and then be difficult to judge its degree of aging by " dusting ".
Summary of the invention
The application aims to solve at least one of the technical problems existing in the prior art.For this purpose, an object of the present invention
It is to provide a kind of degree of aging based on composite insulator powdering grading and determines method.This method is sentenced by the grade of " dusting "
