Vacuum switch, exciter contact arrangement

摘要

The arrangement for making contact with and exciting a magnetic field parallel to an arc is intended to be provided with a considerably smaller structural height, in particular, than known designs and, at the same time, also with a smaller external diameter. The mechanical strength and the internal electrical conductivity are intended to be increased, in order to reduce current heating. This object is achieved as follows: Concentrically arranged bodies 3 in the form of circular arcs have inwardly pointing projections 4, in the form of brackets, on the one side. Connecting bodies 2 which lead to a central current conducting body 1 are connected on the other side. This system of current conducting bodies produces an exciter winding which is approximately equivalent to a somewhat open eye. A flat contact and electrode body 7 is supported on the relatively large-area projections 4. Together with the exciter system 6, it provides the exciter contact 9. The cross-section of the bodies 3 which are in the form of circular arcs can be rectangular or also angular in order to reduce the diameter. <IMAGE>
