【 摘 要 】

In actual operations, the surface insulation strength of metal oxide line arrester can be thus decreased due to inevitably dirt and icing, and the flashover voltage can be significantly reduced, which threatens the operation safety of the entire transmission line. Therefore, in this paper, the internal and external electric field and potential distribution of a 35kV line arrester under operating voltage are studied quantificationally. ANSYS and COMSOL finite-element software was used to calculate the field and potential distribution of the arresters under clean, polluted and icing condition. Based on the analysis of the electric field distribution, the main influence factors of the electric field and potential distribution as well as the equivalent calculation method under different environmental conditions of the arrester are obtained, which can give help to the design and application of line arresters under different environmental conditions.
