Definitions

  • the invention relates to a switching device for an electric
  • Such switching devices typically include single-break or double-break contact arrangements.
  • the switch has an insulating housing, in which two chambers are formed, of which a first chamber acts as an extinguishing chamber and a second chamber with a comparable volume as a connection chamber.
  • a simply interrupting rotary contact is movable in a bearing, wherein the rotary contact is designed as a two-armed lever, the first lever arm carries a contact piece, which comes with a fixed contact on a first power supply rail in switching contact.
  • the second lever arm of the rotary contact is connected to a flexible conductor which is in conductive connection with a second power supply rail.
  • a switching device which includes a double-breaking rotary contact having a switching drive associated with each pole.
  • the rotary contact is rotatably mounted in bearings in the insulating housing about an axis perpendicular to the longitudinal extent of the rotary contact.
  • the actual switch consists of two fixed contacts connected to busbars, and a floating, two-armed trained rotatable contact piece, which carries end contacts, which cooperate with the fixed contact pieces.
  • Two contact pressure springs preferably designed as torsion springs, are supported on a bearing pin on the rotary contact piece and each exert a directed in closing movement torque on the rotary contact piece.
  • the known switching devices thus have a fixed contact and a movable contact piece.
  • the fixed contact limits the distance to be reached between the contacts.
  • DC applications DC applications
  • AC applications AC applications
  • two existing current paths are connected in series.
  • a four-pole AC switching device can be used in which two phases are connected in series, e.g. Moeller switch-disconnector for 1000V DC like N2-4-160-S1-DC up to N4-4-1400-S1-DC.
  • the object of the present invention is to provide a switching device for a low-voltage electrical switching device, in particular for DC applications, which avoids these disadvantages.
  • the switching device is characterized in that there are two movable contact pieces for each phase.
  • the two switching pieces of a phase are mounted via a lever system in the housing of the switching device.
  • this lever system each comprises a guide and a pivot lever, which are each secured with a rigid axle on the housing of the switching device and with a movable axis on the respective contact piece.
  • the swivel lever is moved from the ON position to the OFF position, thereby pivoting the two contact pieces far apart.
  • the switching device is therefore particularly suitable for DC and high voltages where large opening distances are required to shut down.
  • the levers are connected via movable joints with the switching pieces, that the joints move in the case of switching on circular arcs.
  • the levers are made of insulating material.
  • the levers include a core and a shell.
  • the core material of a heavy-duty material, such. Steel or aluminum.
  • the jacket material can consist of insulating material.
  • contact force springs engage the pivoting lever. It has proved to be advantageous to design the contact force springs as tension springs, which exert a force on the contacts in the ON position, which acts in the direction of the respective other contact piece.
  • the contact pieces comprise contact plates at a first end.
  • the trajectory through which the contact plates pass during their switching movement is accompanied by a quenching chamber. It has proved particularly advantageous to design this quenching chamber continuously over the entire trajectory traversed by the contact plates.
  • the switching device according to the invention is suitable for AC applications, but especially for DC applications.
  • FIG. 1 shows a schematic diagram of the switching device (100) according to the invention in the ON position.
  • the shift apparatus (100) includes two movable shift pieces (400) each movably supported at a first end of a guide lever (210) and a swing lever (220) in bearings having movable shafts (216, 226).
  • the guide lever (210) and pivot lever (220) are mounted with their respective second end by means of bearings with a rigid axis (215, 225) in a housing (not shown).
  • the movable axes of the guide levers (216) can move around their rigid-axis guide-lever bearings (215) on a circular path (218) in space.
  • the movable axes of the pivoting levers (226) may also move on a circular path (228) about their rigid-axis pivotal lever bearing (225).
  • the contact force is applied by means of contact force springs (300) which act on the pivoting levers (220). But it is also possible to let contact force springs (300) at other locations of the pivot lever (220) or on the contact pieces (400) attack itself.
  • the pivoting lever (220) is shown here in simplified form to depict the rigid connection of the pivot points (225) and (226). In some embodiments, this function is implemented by a shift shaft.
  • the guide lever (210), as well as the pivot lever (220) may be made of insulating material.
  • the guide (210) and pivot lever (220) of a sandwich with a core and a shell, wherein the core material may be a mechanically stable material that need not be insulating, and the jacket material may consist of a Insulant exist.
  • FIG. 2 is a schematic diagram of the switching device (100) according to the invention shown in the OFF position. Both contact pieces have been rotated in space around the movable axes of guide lever and pivot lever (216, 226), said movable axes (216, 226) have moved on their circular paths (218, 228) accordingly. Although guide and pivot levers (210, 220) have moved only slightly, the end contacts (410) of the contact pieces have moved very far apart. Furthermore, one along the trajectory describing the end contacts (410) in their opening path is a continuous arc quenching chamber (600). In the arc quenching chamber (600) arc extinguishing elements (610) are arranged.
  • These arc quenching elements (610) may include sheets that divide and cool the arc thereby depriving it of energy to extinguish it.
  • the arc (500) which arises when switching under a corresponding current load, extends from one contact plate to the other contact plate along this arc extinguishing chamber (600), so that an optimal arc extinction possible is.
  • the contacts are open, the arc with the contact piece (on both sides) forms a current loop, which quickly drives the arc into the quenching chamber and causes the arc to extinguish.
  • FIG. 3 shows a section of the switching device as a schematic diagram in a plan view and as a section.
  • Parts of two housing halves (710, 720) can be seen in the figure, the guide levers with their rigid axles (215) being mounted between these housing halves (710, 720).
  • the switching device shown has per switching piece (400) each on a longitudinal axis with the switching piece (400) lying guide lever (210) and two pivot levers (220), wherein the pivot lever (220) are arranged parallel to the longitudinal axis of the switching piece (400) and laterally of the contact pieces (400).
  • In the housing halves (710, 720) are recesses (730) in which the levers (220, 210) and axes (216, 226) can move.
  • the two housing halves (710, 720) together form the housing of the switching device, the separation extending in the direction of the longitudinal axis of the contact pieces (400).
