Definitions

  • the invention relates to a switching device with vacuum switching chamber in which at least one movable contact piece is arranged, according to the preamble of claim 1.
  • vacuum interrupters which have a drive or a drive option for each separating stroke (switching path).
  • VK vacuum interrupter chamber
  • one is permanently installed in the VK, one is movably arranged on a supply line. The movement of the arranged in the VK contact piece via the supply line and a bellows.
  • two switching paths here two vacuum switching chambers, are connected in series.
  • VK vacuum interrupters
  • the two contacts are acted upon by a common drive. It is also advantageous that the two contacts are formed by three contact pieces. In a further advantageous embodiment, it is indicated that one of the contact pieces is driven directly forcibly guided by the drive, while the other contact piece is driven indirectly by spring force and in at least one Actuate direction along or trailing.
  • the accompanying or trailing contact piece is surrounded by a cup-shaped arrangement.
  • cup-shaped arrangement with the contact piece in one piece or at least firmly connected.
  • cup-shaped arrangement is provided with an opening through which a contact piece is arranged, which has effective contact surfaces on both sides.
  • At least one of the two supply lines is made of copper.
  • At least one of the contacts is made of a copper-chromium alloy.
  • a special matched material combination is that one of the contacts, or the contact surfaces of the one contact made of a tungsten-copper alloy or a tungsten carbide-silver alloy, wherein the contact pieces of the other contact consists of a copper-chromium alloy.
  • both switching sections are in series; the standard contact pressure force for a VK must be applied by a switching device.
  • the arrangement in which the central contact area is formed by or surrounded by a cup-shaped arrangement while keeping it floating has enormous advantages both in arc extinguishing and dielectric strength advantages.
  • FIG. 1 shows a load switch - Vacuum switching chamber (3) with two integrated switching paths between the contact pieces (7-8 and 8-9).
  • One side of the Vacuum switching chamber is equipped with a movable supply line (2). Via a bellows (1), the supply line (2) and also the contact piece (7) can be moved within the VK. The insulation between the components (4) and ((10) fixed contact side) of the VK takes over the insulator (6).
  • the supply line (2) is moved together with the component (8) arranged movably in the vacuum interrupter chamber.
  • the component (8) is connected via a Randbord on the insulator (6) with a spring member (5).
  • the bias allows the contact stroke (8-9).
  • After reaching a preset contact stroke of the switching path (8-9) opens the switching path (7-8), it is opened, the second contact section.
  • a Hubbegrenzung of the components (8) can be done by this or another edge board (not shown here)
  • FIG. 2 is a similar load switch shown with small changes compared to the illustration FIG. 1 , FIG. 2 therefore also shows a load switch - Vacuum switching chamber (3) with two integrated switching paths between the contact pieces (7-8 and 8-9).
  • One side of the vacuum interrupter chamber is equipped with a movable supply line (2). Via a bellows (1), the supply line (2) and also the contact piece (7) can be moved within the VK.
  • the insulation between the components (4) and ((10), fixed contact side consisting of a lid and a fixed contact carrier)) of the VK takes over the insulator (6).
  • the supply line (2) is moved together with the component (8) arranged movably in the vacuum interrupter chamber.
  • the component (8) is connected via a Randbord on the insulator (6) with a spring member (5).
  • the bias allows the contact stroke (8-9). After reaching a preset contact stroke of the switching path (8-9) opens the switching path (7-8), it is opened, the second contact section.
