电磁斥力机构优化研究综述OA

For meetting the continuously increasing demand of high-voltage direct current(HVDC)circuit break-er,continuous optimization research on electromagnetic repulsion mechanism is required.The working principle and development trend of the electromagnetic repulsion mechanism are described,the current optimization methods to im-prove the driving efficiency of the mechanism are sorted out and summarized,and the prons and cons of different opti-mization methods are analyzed.Moreover,the research progress on optimization of impact stress in transmission sys-tem is introduced in detail.The current buffer performance optimization pattern is summarized.The study shows that,for long-stroke drives,the composite structures have better prospects.In view of the current status of optimization re-search,critical unsolved issues are identified,and future research efforts are suggested to focus on the optimization of the excitation circuit.
