Abstract

Abstract:

The arc generated during the breaking process of relay contacts is one of the main reasons for electrical erosion of the contacts,which leads to relay failure.In order to facilitate the analysis of AC arc physical characteristics,through the secondary development of Fluent,the magneto-hydrodynamic (MHD) model of 3D AC arc is established based on the fluid dynamics equation and the electromagnetic field equation.Combined with the actual movement process of the contact,the dynamic process of the AC relay breaking arc is calculated and analyzed.By comparing with the measured data,the accuracy of the arc simulation is verified,which has certain guiding significance for the further understanding of AC arc characteristics and the optimizing product design.

Key words: AC electromagnetic relay, dynamic arc, magneto-hydrodynamic(MHD) model, Fluent
