文摘

This paper presents the thermal analysis of a high-current dc disconnector which will be used in ITER poloidal field converter. The analysis is based on the finite element method, and thermal-electric module in ANSYS Workbench is adopted. An analysis model involving the effect of contact resistance is first built and then a thermal simulation is performed under the nominal working condition. In addition, the temperature rise test of the dc disconnector prototype has been done to verify the analysis result. The results from the simulation and the prototype test are consistent with each other very well. Proved by the test result, the analysis method presented in this paper is of valuable reference for the structure design of high-current dc disconnectors.
