Abstract

In IMs paper, magnetic Geld characteristics in spiral-type transverse magnetic field (TMF) contacts were studied through simulation.3D finite element models of spiral-type TMF contacts were built. In order to find out the influence of breaking currents and structural parameters on magnetic blow force and B-field, models with different breaking currents and other structural parameters such as slot width and gap distance were simulated. As the arc column moved on the contact, the calculation of magnetic blow force and B-field was also carried out, and the relationship between magnetic blow force, B-field and the position of arc column was investigated. The results in this paper could provide some information for further research on the TMF vacuum arc and the product development of spiral-type TMF contacts.
