330 kV紧凑型铁塔鸟害故障研究

Study on Bird Droppings-induced Failure of 330 kV Compact Towers

以实例从校核紧凑型铁塔电气间隙,仿真模拟鸟粪不同长度、不同位置下落时电场变化、绝缘子沿面场强变化等多方面,分析造成330 kV紧凑型输电线路鸟害故障的机理及主要因素,为后续运维单位开展瓷、玻璃绝缘子清扫,复合绝缘子更换,鸟害重点区域划分,防鸟害决策提供依据。

This paper uses examples to analyze the mechanism and main aspects of the bird droppings-induced failure of a 330 kV compact transmission line from various aspects such as the check of the clearance of the compact iron tower,the simulation of different lengths of bird droppings,the change of the dropping electric field of bird droppings at different positions,and the electric field intensity changes along the insulators.The analysis provides a basis for subsequent operation and maintenance units to carry out cleaning of porcelain and glass insulators,replacement of composite insulators,division of key areas for bird droppings,and decision-making on bird damage prevention.
