断路器单稳态永磁操作机构优化设计

摘要

This paper focued on monostable permanent magnetic operating actuator.It analyzed electromagnetic force on the rated working voltage by modeling and Ansys simulation,optimizing the design by strengthening electromagnetic force and reducing the power of switching on and meeting the condition that works on the work voltage normally to reach the optimization goal.The paper provides reference for monostable permanent magnetic operating actuator’s optimization.%为了提高电磁力、降低合闸功率及满足工作电压范围可靠分／合闸，以断路器中单稳态永磁操动机构为研究对象建模，及Ansys仿真分析其额定工作电压下电磁吸力。改进设计了永磁机构，以达到优化目标，为永磁机构的优化设计提供一定参考。
