摘要：

Numerical computations of the free recovery of arc columns in air and nitrogen are presented. In addition to thermal conduction radiation losses are taken into account and the influence of a temperature dependent thermal diffusivity is considered. At short times after interruption a high thermal diffusivity in the core accelerates the conductance decay while at later times the rate of recovery is reduced due to a small diffusivity in the outer regions of the column. For high current arcs radiation is an important loss mechanism immediately after an interruption. © 1968 Springer-Verlag.
