摘要

Abstract

In response to the current challenge of accurately determining the specific heating status of composite insulators with localised temperature rise using infrared detection technology

this paper proposes a novel diagnostic method. This method involves applying a disturbance to monitor the surface temperature rise data of composite insulators and establishing a relationship between the characteristic parameters of the temperature rise curve and the heating type of composite insulators. By leveraging the fact that the surface temperature rise rate of composite insulators is influenced by the heat source’s position

this approach aims to effectively distinguish between the two types of heating that cause localised temperature rise phenomena. The effectiveness of this method is validated through simulations and experiments

and relevant recommendations for engineering applications are provided.
