Abstract
The effect of different parameters on the electromagnetic repulsion mechanism is analyzed in order to design a high-speed direct current (DC) vacuum switch based on electromagnetic repulsion driving. A two dimensional finite element model is established to analyze the dynamic characteristics of the electromagnetic repulsion mechanism based on rational simplication. Detailed investigations are performed by simulation regarding the impacts of various structure parameters of metal disk, capacity and charging voltage of energy storage capacitor, which provide the basis for optimization design. Finally, based on the simulation results, a 12kV high speed switch prototype with an electromagnetic repulsion mechanism and a disk spring mechanism is developed. It can open within 1.8ms from the trip signal, and the travel time is about 5.0ms.
