Abstract

Die Erfindung betrifft eine Kontaktanordnung für eine Vakuumschaltkammer, mit einem festen (10) und einem beweglichen Kontaktstück (11), welche je einen Kontaktträger (14) aus elektrisch gut leitendem Material, z. B. Kupfer, und eine dem anderem Kontaktstück zugewandte Kontaktplatte (19) aus abbrandfestem Material, z. B. Cu-Cr, aufweisen, wobei jeder Kontaktträger (14) einen zylindrischen Abschnitt und einen am kontaktstückseitigen Ende angeordneten kreisringförmigen Abschnitt (15, 15a, 15b) aufweist. Der zylindrische Abschnitt (14) ist mit dem kreisringförmigen Abschnitt (15, 15a, 15b) mittels zweier miteinander fluchtender radialer Stege (16, 17) verbunden und im Bereich der Stege mittels eines schräg verlaufenden Schlitzes (23) geteilt, so daß der Strom über einen der Stege dem kreisringförmigen Abschnitt und von diesem zu einem die Stege in Einschaltrichtung überragenden Vorsprung, auf dem die Kontaktplatte (19) befestigt ist, fließt.

Figure 00000001
The invention relates to a contact arrangement for a vacuum interrupter chamber, with a fixed (10) and a movable contact piece (11), each of which has a contact carrier (14) made of electrically highly conductive material, e.g. B. copper, and a contact plate facing the other contact piece (19) made of erosion-resistant material, for. B. Cu-Cr, each contact carrier (14) having a cylindrical section and an annular section arranged at the contact piece end (15, 15a, 15b). The cylindrical section (14) is connected to the annular section (15, 15a, 15b) by means of two radial webs (16, 17) aligned with one another and divided in the region of the webs by means of an obliquely extending slot (23), so that the current flows over one of the webs flows from the annular section and from this to a projection which projects beyond the webs in the switch-on direction and on which the contact plate (19) is fastened.
