FLASHOVER PERFORMANCE OF 330kV ICE-COVERED COMPOSITE INSULATORS OF DIFFERENT SHED PROFILES

摘要：

The study explores the effects of shed profile on icing condition of insulators and 50% icing flashover voltage through a large number of tests on five types of composite insulators with different shed profiles in the artificial climate chamber. The results indicate that under the same icing condition, the states of ice on insulators of different shed profiles are obviously different and 50% icing flashover voltage can be significantly increased by optimizing insulator shed profiles and reasonably placing big sheds.
