To predict the thermal behavior of switchgear quickly, a 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 generator, and it is solved using finite difference method (FDM). The main circuit and the control system are connected by thermal resistor network, which solves the problem of multi-sources interaction in the TNFDA. The temperature of conducting wires is calculated according to the heat transfer process and the fundamental equation 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. |
