摘要:
在实际运行中,避雷器表面覆冰会导致其绝缘强度降低,在外加电压作用下,有可能引起输电线路的外绝缘闪络,对输电线路的安全稳定运行构成威胁。因此,开展内间隙线路避雷器在覆冰状态下的电场分布研究,有着十分重要的意义。本文通过有限元计算方法,得到了清洁以及不同程度覆冰条件下35 kV内间隙避雷器的电场和电位分布,根据仿真结果分析了避雷器表面覆冰状态、伞裙结构、电极类型等因素对带间隙避雷器电场分布的影响。本文所做研究可以对线路避雷器绝缘结构设计提供参考。
Abstract:
During actual operations, the insulation strength of arrester surface decreases due to icing, which can cause insulation flashover and threaten the safe and stable operation of the power system under normal working conditions. Therefore, it is necessary to study the electric field distribution of inner-gapped line arresters under icing conditions. The electric field and potential distribution of a 35 kV internal gap arrester under the condition of clean and icing are calculated using finite element analysis software. According to the simulated results, the author analyzed the influence of surface icing condition, sheds structure and electrode type on the electric filed distribution of gapped arresters. The study in this paper can provide references for the insulation structure design of line arresters.
