Definitions

  • the invention relates to a metal-encapsulated, gas-insulated high-voltage switch according to the preamble of claim 1.
  • the movable contact piece is assigned a piston arrangement with an insulating nozzle, in which the gas pressure is increased during a switch-off operation and supplied to the arc.
  • the actual quenching chamber i.e. H. the area in which the arc is extinguished is separated from the remaining area of the encapsulation either by an insulating cylinder or by the fact that the insulating nozzle is guided in a guide cylinder on the contact housing of the fixed contact piece.
  • the object of the invention is to provide a high-voltage switch of the type mentioned, in which a disconnector function is also created.
  • the movable contact piece can be moved together with the contact housing for the movable contact piece in the switch-off direction, but also the fixed contact housing against the switch-off direction of the movable contact piece, until a gas path of a certain length between the contact housing of the movable contact piece and the contact housing of the fixed one Contact piece is reached.
  • the contact housing can also be driven in addition to the normal switch-off movement, so that the same function of a separating section is generated by actuating the contact housing.
  • the switching device which is a high-voltage circuit breaker and has the reference number 10 as a whole, contains a fixed contact piece housing 11 in which a rod-shaped fixed contact piece 12 is arranged; how the fixed contact piece is held within the fixed contact housing 11 has no significance for the invention.
  • the switching device 10 also has a movable contact piece 13, which is attached to a switching tube 14 and is surrounded by an insulating nozzle 15, which has a section 16 with the smallest diameter, which extends towards the fixed contact piece 12 via a conical region 17 to a section 18 large diameter expanded.
  • the fixed contact piece 12 passes through the section 16 and the movable contact piece 13 in the switched-on state and via channels 19 arranged in the insulating material nozzle 15 is supplied according to the direction of arrow P to the arc 20 which is burning through the section 16 insulating gas, here SF 6 gas, so that the Arc 20 is blown and goes out.
  • the gas flow P can be generated by an additional volume (not shown), possibly using the energy of the arc 20 itself.
  • Such switches are known as so-called blow piston or auto blow switches. However, the invention is not limited to such switches.
  • the movable contact piece 13, the drive tube 14 and the insulating nozzle 15 are accommodated in a housing 21; additional contact pieces that can carry the nominal current are not shown for the sake of clarity.
  • the switching device 10 according to FIG. 4, as can be seen from FIGS. 1 to 3, is accommodated in a metal encapsulation 30 which is cylindrical in the case of a single-pole arrangement and possibly oval in the case of a multi-pole arrangement. It is connected at its end faces by means of a cover 31 and 32 and in the area of the end faces, forming a V-shape, leads 33 and 34 are provided transversely to the central axis of the metal encapsulation 30, which are designed as cable terminations and through which current-carrying conductors 35 and 36 pass are.
  • the conductor 35 is electrically conductively connected to the movable contact piece within the contact housing 21;
  • An extension 37 is arranged on the fixed contact housing 11, which is guided through a guide 38 with the interposition of so-called multi-lamella contacts 39, which is electrically conductively connected to the conductor 36.
  • a drive 40 Connected to the drive rod 14, which is led out of the contact housing 21, is a drive 40 which has a piston-cylinder arrangement 41, the piston rod 42 of which is connected to the drive rod 14 via a deflection lever arrangement 43 which is mounted in the axis of rotation 44.
  • the extension 37 connected to the fixed contact housing 11 is connected by means of a coupling rod 45 to a bell crank arrangement 46 which is rotatably mounted at 47 and is connected to a drive 48 which, like the drive 40, has a piston-cylinder arrangement 49, the piston rod 50 is connected to the lever arrangement 46.
  • the drive 48 can also be implemented with a motor spindle arrangement, since the movement by the drive 48 is relatively slow compared to the movement which the drive 40 carries out, since only a separating movement has to be carried out.
  • the disconnector movement can also be carried out by a drive which is arranged on the same side as the drive 40 when the contact housing 21 is moved in order to achieve the disconnector movement. Then the contact housing 21 must have corresponding contact elements, the z. B. correspond to the multi-lamellar contacts 39, slidably guided with respect to the conductor 35 and connected to it in an electrically conductive manner.
  • a two-position drive would be used as the drive 40, which first executes the circuit breaker movement and then connects the disconnector movement.
  • the drive 48 could also be arranged on the same side as the drive 40; in this case the drive 48 would move the contact housing 21.
  • the metal encapsulation 30 is supported on legs 51, 52 on the floor N-N. 1 is the switch-on position, whereas FIG. 2 shows the switch-off device 10 in the switch-off position, which is illustrated in FIG. 4.
  • the insulating nozzle 15 can be seen between the contact housing 21 of the movable contact piece and the fixed contact housing 11. In the position shown in FIGS. 2 and 4, the arc is blown and extinguished.
  • the contact housing 11 is displaced to the right by means of the drive 48 in the guide 38, so that a distance t is formed between the free end of the nozzle 15 and the free end of the housing 11. 3 is the disconnected position.
  • the electrical switching device also has an insulating material cylinder, as is represented, for example, by the dashed line 51 in FIG. 4, then the insulating material cylinder 51 is also moved together with the insulating material nozzle 15 in the switch-off direction and the fixed contact housing 11 is also separated from the insulating cylinder during the separating movement.
  • the separation distance t is necessary, see FIG. 3.
  • the invention is illustrated using a so-called dead tank switch; the invention can of course also be used with any other gas-insulated switch.
