Abstract Though there are many test researches about the icing characters of insulator abroad and domestic, the Effects of icicles during insulator icing has not been investigated specially. With the help of Fluent software, this paper calculated the air flow fields and water droplets trajectories around the insulator with different-length icicles based on hydromechanics and particle track method. And the influences of different length icicles were analyzed according to the air flow field characteristics and the changing of collision rates α₁of water droplets on insulator surface. On principle of heat balance and mass conservation, taking the loss of flowing water on insulator surface and the changing of collision rates α₁ into consideration, the equation of frozen rates α₃ was obtained and a model for calculating icing thickness on insulator surface during wet-growth icing was built. In the validation part, a series of wet-growth icing tests on both insulators XP-160 and FXBW-110/100 under different environment temperatures and wind speeds were conducted in artificial climate chamber. The icing thickness data calculated according to numerical model were compared to what obtained in tests, it shows that the test results from two insulators are correspond to model’s calculation within 10% of average error. The increasing of icing thickness on porcelain insulator is faster than composite insulator. With increasing of icicles, the growing rates of icing thickness of both insulators decrease.

Key words： Ice-covered insulator wet-growth icicle icing thickness
