VACUUM SWITCH TUBE

摘要

In order to design a vacuum switch tube (1) having a housing which has two insulating housing regions (9, 10) arranged and designed symmetrically in respect of a center plane (S), wherein each of the two insulating housings (9, 10) comprise a plurality of insulating housing parts (11, 12, 13, 14, 15, 16) and wherein shielding elements (18, 19, 20, 21, 22, 23, 24, 25) extending into the interior of the vacuum switch tube are arranged between neighboring insulating housing parts and between insulating housing parts and neighboring additional housing parts (6, 8, 17), said shielding elements having improved dielectric properties and a simultaneously material-saving structure. According to the invention, the geometrical dimensions of the shielding elements (18, 19, 20, 21, 22, 23, 24, 25) are determined in dependence on a connected voltage and a possible critical field strength between neighboring shields.
