Definitions

  • the invention relates to a support frame for an electrical switch of an encapsulated switchgear panel, in particular a medium-voltage switchgear panel, which can be moved between an operating position, a test position and a disconnected position, a plug connection being provided for connecting secondary lines and for carrying out connecting pieces of the electrical switch are provided in a bulkhead openings which can be closed by means of panels.
  • Such a support frame is known, for example, from the chapter “8.2.4 Metal-encapsulated air-insulated switchgear panels according to DIN EN 60298 (VDE 0670, Part 6)” of the “ABB Pocket Book Switchgear”, 10th edition, Cornelsen Verlag Berlin, page 392.
  • a metal-partitioned control panel depicted, which is subdivided into several subspaces, such as a busbar compartment, a cable connection compartment and a switch compartment.
  • An electrical switch is arranged in the switch room. This electrical switch can be moved between an operating position, a test position and a disconnected position. In the disconnected position, the connection pieces of the electrical switch are electrically separated from corresponding mating contact pieces, the secondary lines are separated by means of a plug connection.
  • connection pieces of the switch are separated from the counter contact pieces.
  • the secondary lines of the switch and switch panel are connected to one another via the plug connection.
  • the connection pieces of the switch contact the mating contact pieces.
  • the secondary lines are connected to one another by means of the plug connection.
  • the connecting pieces of the electrical switch are arranged so that in the operating position they protrude through openings provided in a bulkhead into the busbar space or the cable connection space. These openings can be closed by means of shutters in order to ensure that the bulkhead has a partition effect even when the electrical switch is removed or in a disconnected or test position.
  • the electrical switch is moved on the support frame between the operating position, the test position and the disconnected position by means of complex mechanical devices.
  • the invention has for its object to design a support frame of the type mentioned in such a way that the method of the electrical switch is made possible by means of a simplified, safe and inexpensive construction.
  • the object is achieved by a single mechanical control module integrated in the supporting frame, which controls the actuation of the plug connection and the panels and the method of the electrical switch between the disconnected position, the test position and the operating position.
  • the support frame represents a cassette-like insert, which can be easily replaced with another support frame (possibly with an electrical switch arranged on it). All control processes relating to the movement of the electrical switch on the support frame are initiated by the mechanical control module itself. Auxiliary devices such as additional gears, deflection devices, blocking levers, etc. are no longer necessary with such a construction. Due to the integration into the supporting frame, very simple mechanical constructions can be selected. Elaborate lever arrangements for the transmission of forces are avoided.
  • control module can advantageously be made for the control module to have a continuous first link and a bolt which is guided therein and, when it moves, successively engages and disengages with various entrainment devices.
  • the driving devices are designed in the form of a plate. det and are guided on the outside of the control module by means of guide bolts in elongated holes.
  • the entrainment devices are plate-shaped, this results in a very small overall height. Despite the low overall height, such plate-shaped entrainment devices can transmit very high forces.
  • By guiding the entrainment devices on the outside of the control module it is possible to arrange a large number of such entrainment devices in such a way that they do not interfere with one another in their functioning. It is thus possible to guide the entrainment devices in elongated holes in a simple manner by means of bolts. Furthermore, it is possible to attach arms to the driving devices for the transmission of movements.
  • a further advantageous embodiment provides that the bolt controls both the movement of the electrical switch and transmits driving forces for the movement of the electrical switch.
  • the bolt is essentially parallel to one on a drive spindle by means of a pivotable drive lever drivable and connected to the drive lever nut is movable.
  • the bolt can be moved essentially parallel to a drive spindle, the necessary movement of the movable electrical switch between the operating, test and disconnected positions can be achieved in a favorable manner.
  • the drive force can be transmitted from the drive spindle to the bolt in a suitable manner by means of a drive lever.
  • This construction is very robust and suitable for transmitting high driving forces.
  • the use of a drive spindle makes it possible, due to its self-locking, to automatically inhibit a force which reacts from the switch via the bolt and the drive lever.
  • spring-loaded pawls are connected to the various entrainment devices, which pawls are guided and can be latched in further scenes.
  • the pawls can be actuated by the bolt itself. If the bolt is provided as an actuating device for the pawls, it is very simply possible to move the driving devices only when the bolt is in the areas provided for this purpose.
  • a common link plate has the first link for guiding the bolt and the further links.
  • first backdrop and the further backdrops are arranged in a common backdrop plate, then once this backdrop plate has been manufactured, it is no longer possible to change the position of the individual backdrops relative to one another. This ensures that the movement sequence is reliably controlled even after a large number of movement processes. Furthermore, complex adjustment work during assembly is avoided.
  • a further advantageous embodiment provides that the drive lever assigned to the pin is guided between two spaced-apart link plates and each of the link plates has the continuous first link, the pin being guided in both links.
  • one of the entrainment devices is connected to a movable arm for actuating the plug connection, on which a connector part is floatingly mounted.
  • a movable arm is assigned to one of the entrainment devices, this can be used in a simple manner to move part of the plug connection.
  • a connector part of the plug connection it is now possible to connect a connector part of the plug connection to a corresponding counterpart.
  • the floating mounting of the connector part makes it possible to compensate for tolerances with regard to the mechanical arrangement of the connector part and the associated counterpart of the plug connection and to relieve the plug connection itself of external forces.
