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 invention is thus based on the object of significantly increasing the switching capacity and the dielectric strength.
- the core of the invention here is to realize a series contact constructively within a vacuum interrupter chamber, that within a vacuum interrupter chamber two series-connected contact arrangements with a total of two apparent contact levels are arranged.
- the two series contacts are arranged within a vacuum interrupter chamber.
- the two contacts are formed by three contact pieces.
- one of the contact pieces is driven directly forcibly guided by the drive, while the other contact piece is indirectly driven by spring force and in at least one direction of actuation mitlauf 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.
- Vacuum switching chamber is still another internal switching chamber, which is arranged therein, that the two resulting contacts are connected in series in the switching path.
- Example that at least one of the contact pieces consists 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.
- Figure 1 shows a load switch - vacuum switching chamber (3) with two integrated switching paths between the contact pieces (7-8 and 8-9).
- 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 via a Randbord on the insulator (6) with a spring member
- FIG 2 a similar load switch is shown with small changes compared to the illustration of Figure 1.
- Figure 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 via a Randbord on the insulator
- 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.
