控制与保护开关电器电磁机构运动轨迹仿真研究

Simulative Study on Movement Trajectory of Control and Protective Switching Device Electromagnetic Body

针对控制与保护开关电器(CPS)电磁铁长期吸合、释放过程造成的线圈骨架磨损和变形问题,根据动态仿真轨迹,提出了线圈骨架限位槽的改进措施,并通过仿真验证了其可行性。仿真结果显示,改进措施能达到降低轴和限位槽间的摩擦力,减少E形电磁铁工作时产生的噪声,提高E形电磁铁的工作稳定性的目的。

Aimed at the attrition and deformation of coil framework in the course of E-shaped electromagnet closing up and separating from the other for quite large number of times, and according to the simulative movement trajectory, an improvement method applied to the coil framework limit groove was put forward, and its feasibility was verified. The simulative results reveal that the improvement method lowers the friction among the axis and limit groove, reduces the noise caused by the operation of E-shaped electromagnet, and improves the stability of E-shaped electromagnet.
