Voltage Driven Transient Finite Element Analyses for Design Studies on Low Voltage Contactors

摘要

Voltage driven transient finite element analyses with a direct circuit coupling are carried out for the behaviour of low voltage AC contactors. Thereby, different arrangements of the shading rings are analyzed in detail. A comparison of the steady-state current characteristics in dependence of the air-gap obtained from the numerical calculations and from measurements shows a very good agreement.
