摘要:
Getter device for positioning in a vacuum interior space (12) of a vacuum circuit breaker (10). The getter device comprises at least one tablet (2) of getter material. The interior space (12) comprises a metal wall (13, 16, 11, 17, 19, 21) with a groove (4) in which the at least one tablet (2) can be placed, and the at least one tablet (2) can be fixed by at least one depression in an edge (7; 9) of the groove (4). The metal wall may be formed by a contact pin (13, 16) of one of the contacts (14, 15) or a wall of the enclosure, which comprises an end cap (11), a first shielding (17), a second shielding (19) or a second end cap (21).
摘要:
The invention relates to a vacuum interrupter with one movable contact fixed on a movable contact stem, and at least one fixed contact with a fixed contact stem, wherein fixed and movable contact or contacts are located in a electrically insulating tube, which is vacuumtightly closed by metal lids at boths sides of the insulating tube, wherein the fixed contact stem is placed vacuumtightly on one of the metal lids, and the movable contact stem is guided trough an opening of the opposite metal lid via an axially extendable vacuumtight bellow, according to the preamble of claim 1. In order to get better performance for twist protection, additionally with lower costs, the invention is, that in order to create a twist protection of the movable contact stem (4) a ring disc shaped plastic part (11) with a central opening, through which the movable contact stem (4) is guided, is connected externally to the vacuum interrupter in such, that inner key flats (12) inside the opening of the plastic part (11) complementarily fits closely to external key flats (10) of the movable contact stem (5).
