Three dimensional temperature field modelling and simulation for the deicing of post insulators

The icing of pillar insulators in actual substation operating environments can lead to potential hazards such as power outages. Effective deicing of pillar insulators is of great significance. As an emerging deicing method, jet heating deicing lacks existing models. This study innovatively explores the temperature field distribution through advanced numerical simulation methods based on COMSOL, unlike traditional methods that rely mainly on experimental measurements or simple theoretical models. It further describes the process of establishing a three-dimensional model in detail. Through simulation analysis, the three-dimensional temperature field distributions of post insulators under different working conditions or heat source parameters are obtained, visually presenting the change trends and distribution characteristics of temperature. The research results provide a theoretical basis for in-depth understanding of the heat transfer mechanism during the deicing process of post insulators.
