N2 - This paper presents a novel electromagnetic repulsion mechanism with pressure buffer included, in which the influence of flow field variation on motion characteristic of mechanism is investigated in detail. A new 2D-axisymmetric cylindrical coordinate model is constructed and described by a set of multi-physical equations reflecting the flow field, transient electromagnetic field, electric circuit and mechanical motion. The motion performance of mechanism and the pressure drag caused by the high-speed movement of metal plate are analyzed under different opening speeds. It shows that the pressure drag has a strong buffer effect on the mechanism motion. Then, the influence of laminar and standard k - ϵ models on the pressure distribution and motion characteristics is compared. Finally, a 200kV prototype of high speed switch based on electromagnetic repulsion mechanism is built, in which the pressure buffer is included. The motion characteristic test shows that the designed mechanism has sufficient dynamic performance with satisfied pressure buffer. Meanwhile, in comparison to the laminar model, the turbulence model is more suitable to predict the dynamic characteristics of mechanism.
