    摘 要:针对现有10 kV直流快速操作机构对加工和装配工艺要求高的问题,提出了一种对工艺要求不高的双向永磁保持直流快速操作机构。建立了电磁斥力机构的仿真模型,通过Infolytica磁场仿真确定了斥力线圈参数,得出电工纯铁线圈骨架比环氧树脂和聚四氟乙烯材料更有利于降低分闸时间。通过对原理样机的试验测试,验证了仿真优化的正确性及双向永磁保持直流快速操作机构的可行性。

    Abstract: Aiming at the existing problem that the 10 kV direct current operation mechanism has high requirements on processing and assembly technology, this paper proposed a fast mechanism of two-way permanent magnet maintenance which had low requirements on technology. A simulated model of electromagnetismrepulsionmechanism was established to determine the parameters of the repulsion coilby Infolytica magnetic field simulation, so as to conclude that the electrical pure iron coil framework is more conducive to reducing the opening time than the material of epoxy resin and teflon. The experiment of principled sample machine verifies the correctness of simulating optimization and the feasibility of a fast mechanism of two-way permanent magnet maintenance.
    Key words: direct current circuit breaker; direct current high-speed operation mechanism; two-way permanent magnet maintenance; opening time; coil framework
