【Abstract】 A numerical analysis approach to calculate the thermal propagation of static and dynamic electric contact was given by deducing the potential field distribution and the Joule heat distribution in the bulk of contact.The input thermal source to the contacts due to arc was molded by the Gauss thermal source,the moving boundary problem was transformed into “single phase”nonlinear thermal conduct by applying the method of large heat capacity,therefore,the large heat capacity model for thermal propagation of contacts erosion by arcs was constructed.更多还原
