| Abstract: | Mathematic models of three types of heat transfer for electromagnetic system of AC contactor were analyzed, and through further-developing the ANSYS software, firstly heat generation power of coil electromagnet and shadow ring were calculated with magnetic circuit method considering nonlinear character of electromagnet,secondly thermal load was applied to make steady-state thermal analysis with finite element method,iterations continued between thermal analysis results and temperature-dependent parameters until the calculation was convergent. The test results show that the analysis result has high precision. |
