Development of the temperature in a current constriction

  • Ragnar Holm

Abstract

We consider contacts that are heated either by the current which they transport or by heat developed in the contact surface, for instance by friction. In the case of heat generated by friction we anticipate certain problems that, in fact, belong to Part II. The purpose is to achieve a certain unity in the exposition. Equilibrium states have been treated in the foregoing chapters, but in many problems, for instance, those concerning moving contacts, one deals with contact spots of transient duration in which the temperature does not reach equilibrium. In order to obtain a clear conception of their behavior, it is of primary importance to know how the temperature is distributed in their constrictions at various stages of heating.
