Definitions
- the invention relates to a vacuum interrupter with a housing, a first contact system, which comprises a movable contact piece and a fixed contact piece, and a second contact system of a ground contact and a grounded counter contact piece, wherein the ground contact is arranged on a movable, sealing led out of the housing contact rod ,
- Such a vacuum interrupter is known from DE 100 30 670 C2.
- the described vacuum interrupter comprises a first contact system with a fixed contact piece and a movable contact piece, which is connected to a power supply pin as a movable contact rod.
- the interior of the housing of the vacuum interrupter is vacuum-tightly sealed to the power supply bolt by means of a bellows against the environment.
- the first contact system is used to switch or disconnect an electrical connection.
- a contact carrier with a movable contact as a grounding contact of a second contact system wherein the grounding contact with a fixed contact serves as a mating contact piece for grounding the vacuum interrupter.
- the mating contact piece is guided by means of a thick-walled pipe section with a radial connection flange to the outside.
- a resulting during the separation process arc is plasma-physically shielded by a labyrinth-like shielding of the mating contact piece.
- ions of the arc can be attracted to the ground potential of the mating contact piece, which leads to a polarity-dependent switching capacity of the vacuum interrupter.
- Object of the present invention is to provide a vacuum interrupter of the type mentioned, in which an interaction of the arc is prevented with the earthed counter-contact piece.
- this object is achieved in that the first contact system is held in the interior of the housing to vacuum-tight separating means which divide the interior of the vacuum interrupter into a first interior with the first contact system and a second interior with the second contact system.
- the separating means comprise a partition plate held on the housing with a vacuum-tight passage.
- This partition plate is preferably electrically conductive and provides a simple way to divide the interior of the housing of the vacuum interrupter into two mutually vacuum tight sealed interior spaces.
- the movable contact rod extends through the partition plate and is connected in the first interior with the movable contact piece of the first contact system and a bellows forms on the partition plate, the vacuum-tight implementation.
- the bellows is advantageously formed a vacuum-tight passage for the movable contact rod, by which a movement of the movable contact rod is made possible to move the arranged on the movable contact rod contacts between different positions.
- the vacuum-tight passage is formed by a vacuum-tight recessed in the partition contact piece of the fixed contact piece of the first contact system and the movable contact rod forms with its inner end of the movable contact piece of a third contact system whose fixed contact piece is the contact piece.
- the movable contact piece of the first contact system is attached to a further movable contact rod, which extends vacuum-tight in the first interior. Due to the arrangement of the other movable contact rod, the functions power interruption or switching and separation are independently executable independently, resulting in a more compact construction of the vacuum interrupter, since the current interruption and extinction of the arc, a small distance between the movable and the fixed contact piece is sufficient whereas dielectric separation requires greater spacing between the contacts.
- a bellows forms the vacuum-tight implementation of the further movable contact rod.
- a bellows is an advantageous means for forming a vacuum-tight passage for the movable contact rod.
- the fixed contact piece and the movable contact piece are each formed from a copper-chromium material.
- a copper-chromium material advantageously has a high switching capacity with simultaneous switch-on and generates only small overvoltages.
- the fixed contact piece and the movable contact piece are each formed from a tungsten carbide silver material with a silver content between 20 and 50%. Such a material is also suitable for the formation of the first contact system.
- the grounding contact and the mating contact piece are each formed from copper. Copper is a good electrically conductive material and therefore offers advantageous properties for the second contact system as a grounding contact system.
- the grounding contact and the mating contact piece are each formed from a copper-chromium material. Such a material has the advantages already described above and can therefore also be used for the second contact system.
- the contacts of the third contact system are formed of copper. Copper with the properties already described above is a suitable material for the third contact system.
- contacts of the third contact system are formed of a copper-chromium material.
- a copper-chromium material can be used advantageously for, the third contact system.
- FIG. 1 shows a first embodiment of a vacuum interrupter according to the invention
- FIG. 2 shows a second embodiment of a vacuum interrupter according to the invention.
- Figure 1 shows a vacuum interrupter 1 with a housing 2, which comprises a housing plate 3 with a passage 4, a further housing plate 5 and insulators 6, 7 and 8.
