摘　　要：电磁斥力机构是快速开关的核心部件,对其性能及可靠性起关键作用。该文面向具体的工程应用,提出一种定量化设计电磁斥力机构的方法,将组成电磁斥力机构的放电回路、电磁感应、动力传递等各关键部分,通过建立电磁斥力机构全模型耦合分析的方式集成在一起,既考虑机构的快速性,又关注机构零部件能承受的机械载荷及驱动效率。以上述模型和方法为基础,进行工程化的优化设计,最终实现2 ms分闸速度目标,达到设计预期,并应用于重点柔直环网工程的混合型直流断路器中。Electromagnetic repulsion mechanism is the core component of fast switch, which plays a key role in its performance and reliability. In this paper, a quantitative design method of electromagnetic repulsion mechanism is proposed for specific engineering application. The key parts of electromagnetic repulsion mechanism, such as discharge circuit, electromagnetic induction and power transmission, are integrated by the coupling analysis of the whole model of electromagnetic repulsion mechanism, which not only considers the rapidity of the mechanism, but also pays attention to the load that the mechanism can bear. Based on the above model and method, engineering optimization design is carried out, and the goal of 2 ms opening speed is finally achieved. The design expectation is achieved, and it is applied to hybrid DC circuit breaker of key flexible direct loop network project.
