Abstract

 Consider the method of determination of melting the contact details of the equation of heat conduction in spherical coordinates. The calculation of the thermal regime the contact parts are manufactured by the method of a point source as the sizes of the base arc is very small compared to the surface of the contact details. Been determined the temperature distribution of the arc during combustion at cur- rent commutation.
