Miniature Circuit Breaker Electromagnetic Release Simulation and Analysis

摘要

With the three-dimensional field analysis software Ansoft, we establish three-dimensional finite element model of the electromagnetic release, obtain the electromagnetic release static characteristics of electromagnetic force by simulation, and analyze the relationship between the electromagnetic force, the short-circuit current and the air gap size. By Analyzing the dynamic characteristics of moving iron core, different short-circuit current's influence on the velocity and displacement of the moving iron core was gained.
