Abstract
For the short circuit current test requirement of copper platoon at the entrance of a hybrid current-limiting fuse, the magnetic field distribution simulation model of copper platoon in both steady and transient current state were built. The influence of external magnetic field of copper platoon on the sensor measurement accuracy were analyzed in steady and transient state current. COMSOL simulation software was used to find the intersection point of magnetic induction intensity corresponding to steady-state and transient-state current with amplitude of 10 kA to determine the installation position of Hall element. In order to ensure the measurement accuracy, the installation position of Hall element was optimized by adding ferromagnetic materials, and the method of the final installation position of Hall element was obtained and verified by experiments. It was indicated that the simulation results was well consistent with the experiment results, which verified the correctness of the finite element model and the feasibility of the design. This design reduces the error of hall current sensor from 37% to 3.5%, which can be used as a reference for the research and development of small DC hybrid fuse.
