The Simulation Analysis of Electromagnetic Repulsion Mechanism for High-voltage Current-Limiting Fuse

摘要

The research content of this topic is based on Electromagnetic Repulsion Mechanism for High-voltage Current-limiting Fuse, according to the given parameters, and basing on the reasonable simplified, the topic establishes 2D finite element simulation model by using Ansoft Maxwell, and simulates the dynamic characteristics. The influence law of electromagnetic repulsion mechanism will be found out by simulating these influencing factors, such as repulsion mechanism, electromagnetic repulsion, and movement speed. Finally the topic concludes a general design guiding principle which strives to increase the speed of electric repulsion between contacts rapidly and improve the current-limiting ability of current-limiting fuse by producing short circuit current.
