Five structural parameters of contrate contact, such as number and inclination of slot, contact diameter, the depth and thickness of contact cup, are arranged orthogonally to study magnetic characteristics. Experiments based on orthogonal design are analyzed by three dimensions finite element method. The regression equations of the relationship between structural parameters of contact and Lorentz...

Thermal simulations of a large current vacuum circuit breaker (VCB) were performed to study the influence of heat transfer coefficients, contact way and radius of contact face between movable contact and static contact on the temperature rise. Simulation results of natural convection heat transfer characteristic of rectangular fins showed that optimal structural parameters of rectangular fins can...
