| Abstract: | A 3D coupled thermal-electric model of the pre-arcing period for current-limiting fuse was set up to simulate the heating process of fuse element. And the time-current characteristic was simulated by Ansys. The validity of this simulation model and method was verified by the results of experiments. The error of pre-arcing time between simulation and experiment is acceptable technically, which proves the validity of simulation model and method. |
