Composite insulator umbrella skirt aging state analysis method

The invention discloses a composite insulator umbrella skirt aging state analysis method which is characterized by comprising the following steps: acquiring a to-be-tested sample; carrying out microscopic detection on the to-be-tested sample to obtain at least one detection index; and inputting at least one detection index associated with the to-be-tested sample into a preset aging state analysis model to obtain an aging analysis result of the to-be-tested sample. Electro-thermal-chemical combined multi-dimensional detection indexes are introduced, objective weighting is performed on the detection indexes by using an entropy weight method, a composite insulator umbrella skirt aging state analysis model is established, quantitative evaluation of the umbrella skirt aging state is realized, and a power frequency dielectric constant and a dielectric loss factor are obtained by using a non-contact dielectric spectrum test mode. Compared with a contact type dielectric spectrum test mode in the prior art, the test r
