| Summary: | The paper proposes one-dimension model of temperature field with the purpose to calculate plane contact heating under steady-state and transient conditions. The numerical algorithms have been developed to calculate contact temperatures. These algorithms are based on a separate solution of differential equations of electromagnetic and temperature fields. The finite difference method and numerical and analytical method for steady-state conditions have been applied in the calculations. Distribution of temperature along the length of plane and knife-type contacts at various moments of short-circuit conditions has been obtained. The investigations have shown that current conducting parts determine contact temperature in the case of steady-state conditions. In the case of transient conditions there is a possibility of significant over-heating of contact connections. |
