  • This switching tube has no special shielding to protect the inner formed by the annular insulator Isolation distance on, because a relatively wide end face of the annular insulator facing away from the contact area is.
  • the power connections of this well-known vacuum interrupter are - as usual - designed as bolts that passed axially through the respective cap-like metal part are.
  • the two contact pieces are otherwise as Pot contacts executed; but other well-known ones also come Contact forms into consideration (DE 44 22 316 A1).
  • Another Known contact form offer, for example, so-called spiral contacts (English: spiral petal contacts) with in particular flat, plate-like contact electrodes with from the outside Inward circumferential slots are provided. This Slots can each consist of a straight section and of a hole breaking through the contact surface (EP 0 532 513 B1).
  • Vacuum interrupters are already used as switching elements for low-voltage contactors known in which the bellows part forms the outer surface of the housing and on the one hand with the power connection of the movable contact pin and on the other side with a short tubular insulator is soldered vacuum-tight (DE 37 09 585 C2).
  • the bellows can be used with both the isolator and the Power connection of the movable contact pin through a Cutting edge soldering must be connected (DE 195 10 850 C1).

  • the invention provides that the power connections of the two contact pieces as plates are formed, each the bottom area of one of the two cap-like metal parts that continue to form the bellows the wall area of that cap-like metal part forms, which is assigned to the movable contact piece, and that finally a tubular part, the front with the plate-like power connection of the fixed contact piece is soldered to the wall area of the other cap-like Metal part forms.
  • Such a configuration of the vacuum interrupter leads to a flat design with compared to conventional vacuum interrupters significantly reduced overall length. This helps especially the design of the power connections in the form of Sheets instead of the usual cylindrical bolts with, these plates are also the front covers of the cylindrical switching chamber. - The area The design of the new vacuum interrupter can be even clearer emerge if the contact pieces as spiral contacts, especially forms as flat spiral contacts. The usage of spiral contacts also leads to a better one Arc guidance, which results in better switching capacity. So when using flat spiral contacts with a diameter of about 90 mm short-circuit currents up to about 130 kA can be switched.
  • disc-shaped vapor barrier for example consists of a chrome-nickel steel and that in vacuum interrupters with small switching capacity, if necessary mechanical reinforcement of the movable, reduced in thickness Spiral contact can be used.

  • the new construction of the vacuum interrupter makes it possible furthermore, all parts - except the ring-shaped Isolator - self-centering construction so that all Individual parts in a single operation (seal soldering) with each other without using expensive and complex soldering molds can be soldered. It is recommended that the fixed contact piece via a short centering spigot is connected to the plate-like power connector and that the movable contact piece via a contact pin with the associated plate-like power connection connected centered is.
  • the shape of the two contact pieces, especially flat ones Spiral contacts surrounding the tubular part depends on the in each case provided switching capacity. With low switching capacity from about 40 to 60 kA this part can be used as a hollow cylinder be trained. With greater switching capacity, i.e. with larger contact diameters, it is recommended that the tubular part on the annular insulator facing End is provided with a tapered taper; this makes possible the use of an isolator and bellows with a significantly smaller diameter than that of the spiral contacts.
