摘　　要：通过设计带有涡流斥力机构的接触器使之具有短路电流分断性能,利用动力学仿真软件ADAMS并结合有限元仿真软件ANSYS的仿真数据,建立了接触器在高速涡流斥力机构作用下的分断特性模型,得出动铁心和动触头的瞬态位移仿真曲线。利用高速摄像机,拍摄接触器的动铁心和动触头的实时位移变化。从ADAMS仿真数据和高速摄像机拍摄的数据验证了仿真模型和实物模型的准确性。最后通过50kA的短路电流实验验证所设计装置的短路电流分断特性。Contactor with eddy repulsion mechanism is designed to break short-circuit current.Model of contactor breaking based on high-speed eddy repulsion mechanism is established with ADAMS and ANSYS.Both transient displacement curves of moving core and moving contact are obtained.Real-time displacement of moving core and moving contact is recorded by high-speed camera.The accuracy of simulation model and physical model are verified by the data that obtained form ADAMS and high-speed camera in this paper.Also,a 50kA short-circuit experiment is performed to validate the characteristics of short-circuit breaking.
