Ceramic insulator for vacuum switch tubes

摘要

The present invention relates to a ceramic insulator (10) for vacuum switch tubes (1), wherein the ceramic insulator (10) extending along a longitudinal extension (20) and extends into this longitudinal extension (20) forms a cavity (15),the cavity (15) on a first side (30) of the longitudinal extension (20) a first opening (31) and at a second side (32) of the longitudinal extension (20) a second opening (33), which are suitable, by means of suitable connection means (40) to be closed in a gas-tight manner and wherein the closed first opening (35) is suitable, at least one fixed contact (38) into the cavity (15), and the closed second opening (37) is suitable, at least one mobile contact (37) into the cavity (15) to lead,characterized in thatthe ceramic insulator (10) on an inner side of the hollow space (15) one or more, which are perpendicular to the longitudinal extension (20) of the ceramic insulator (10) extending, electrically conductive discharge path (12) under the crusher has.
