Pour prédire rapidement le comportement thermique de l'appareillage de commutation, la méthode d'analyse des différences finies du réseau thermique (TNFDA) est adoptée dans l'analyse thermique des contacteurs CA dans l'article. Le modèle de réseau thermique est construit avec des nœuds, des résistances thermiques et des générateurs de chaleur, et il est résolu à l'aide de la méthode des différences finies (FDM). Le circuit principal et le système de contrôle sont reliés par un réseau de résistances thermiques, ce qui résout le problème de l'interaction multi-sources dans l'application du TNFDA. La température des fils conducteurs est calculée en fonction du processus de transfert thermique et des équations fondamentales de la conduction thermique. Il fournit une méthode pour résoudre le problème des conditions aux limites dans l’application du TNFDA. La comparaison entre les résultats du TNFDA et les mesures montre la faisabilité et la praticabilité de la méthode.

Abstract: To predict the thermal behavior of switchgear quickly, the Thermal Network Finite Difference Analysis method (TNFDA) is adopted in thermal analysis of AC contactor in the paper. The thermal network model is built with nodes, thermal resistors and heat generators, and it is solved using finite difference method (FDM). The main circuit and the control system are connected by thermal resistors network, which solves the problem of multi-sources interaction in the application of TNFDA. The temperature of conducting wires is calculated according to the heat transfer process and the fundamental equations of thermal conduction. It provides a method to solve the problem of boundary conditions in applying the TNFDA. The comparison between the results of TNFDA and measurements shows the feasibility and practicability of the method.
