Original Abstract

The back-commutation and sticking are phenomena which cause an increase in time delay between arc ignition and arc reaching the arc chute. These effects cause increase in total switching time and contact and arc runner wear. This paper gives a comparison of several approaches to reduction of these effects in a medium voltage contactor for traction usage. The three chosen approaches were: changes of the shape of the arcrunners, changes of the pole plates of the magnetic circuit and increase of the ventilation cross section. Metrics on how to compare the performance of these different alterations were given, based on switching times. From the three tested methods the ventilation increase yielded the best results as it both reduced the switching time and time delay caused by the back-commutation and reduced the variation of these characteristics.
