Definitions

  • the invention relates to an electrical switch with two extinguishing nozzles opposite one another at a distance from the separating distance, one of which is attached to a fixed contact tube and the other to a fixed guide tube, with a longitudinally movable switching tube for bridging the separating distance and with a pressure piston pressure cylinder Arrangement for generating an extinguishing agent flow acting on the arc, the switching tube and the movable pressure piston of the pressure piston-pressure cylinder arrangement being coupled to a common drive.
  • the pressure cylinder of the pressure piston-pressure cylinder arrangement is arranged to be longitudinally movable and is rigidly coupled to the switching tube and the drive. During the switch-off movement, the pressure cylinder is therefore moved together with the switching tube in the direction of the pressure piston of the pressure piston-pressure cylinder arrangement. In the course of the switch-off movement, the drive also sets the pressure piston in motion, its movement being opposite to that of the pressure cylinder. This results in a compression or an improvement in the pre-compression particularly quickly during the switch-off process.
  • the object of the invention is to further improve this known electrical switch with regard to the flow of extinguishing agent, this improvement being intended to be achievable with a simple construction and with a low manufacturing outlay.
  • the pressure piston is rigidly connected to the switching tube according to the invention in an electrical switch of the type specified and is located in a fixed pressure cylinder; the pressure cylinder is connected in the region of its end comprising the contact tube to the interior thereof through through openings in the contact tube, and the pressure piston is rigidly connected to a suction piston in a fixed suction cylinder comprising the guide tube, the suction cylinder in the region of its end facing the pressure cylinder via holes in the Guide tube is connected to the interior.
  • a major advantage of the switch according to the invention is seen in its comparatively simple structure; this applies above all to the design of the drive.
  • Another advantage of the switch according to the invention is that, despite a short pre-compression path, a high pressure difference is generated at the Leschdusen. This is due to the fact that an overpressure arises in the area outside the extinguishing nozzles during the pre-compression and at the same time a negative pressure is built up inside the extinguishing nozzles, which is caused by the movement of the pressure piston and the suction piston during the pre-compression phase.
  • the relatively large pressure difference obtained in this way leads to a strong flow of extinguishing agent, which leads to an advantageously short extinguishing time for the arc.
  • Another advantage is that the relatively large pressure difference builds up relatively quickly, so that the switch according to the invention can be extinguished relatively early.
  • the pressure cylinder of the pressure piston-pressure cylinder arrangement and also the suction cylinder can each consist of a separate component.
  • the pressure cylinder and the suction cylinder are made from a single one Cylinder part with an annular partition.
  • the ring-shaped partition divides the only cylinder part into the pressure cylinder and the suction cylinder.
  • the interior of the pressure cylinder is connected to the interior of the suction cylinder via an external pressure line.
  • This pressure line ensures that the pressure inside the pressure cylinder corresponds to that inside the suction cylinder.
  • connection of the interior of the pressure cylinder and the suction cylinder via the pressure line is particularly advantageous if the suction cylinder has a counter-piston at its end facing away from the pressure cylinder, which counter-clockwise movement to the suction piston during the switching-off movement of the drive.
  • the suction cylinder has a counter-piston at its end facing away from the pressure cylinder, which counter-clockwise movement to the suction piston during the switching-off movement of the drive.
  • an embodiment of the electrical switch according to the invention is shown schematically in section in the figure, the right side of the figure showing the embodiment in switched on state and the left side of the figure shows the embodiment in the switched off state.
  • the electrical switch shown contains a fixed contact tube 1 with an extinguishing nozzle 2, which is opposite an extinguishing nozzle 3 of a likewise fixed guide tube 4.
  • the separating section T formed by the extinguishing nozzles 2 and 3 can be bridged by a switching tube 5, which is part of a drive cylinder 6.
  • This drive cylinder 6 is connected to a drive in a manner not shown.
  • a suction piston 7 is fastened to the drive cylinder 6 and can be moved in a suction cylinder 8.
  • a pressure piston 10, which is guided in a pressure cylinder 11, is connected to the suction piston 7 via connecting rods, of which only one connecting rod 9 is shown in the figure.
  • the pressure piston 10, the suction piston 7, the switching tube 5 and the drive cylinder 6 are thus rigidly mechanically coupled to one another.
  • the pressure cylinder 11 and the suction cylinder 8 consist of a single cylinder part which is made of insulating material and is equipped at its end comprising the contact tube 1 with ribs 12 for extending the creepage distance.
  • the only insulating part is divided by an annular partition 13 into the suction cylinder 8 and the pressure cylinder 11.
  • the pressure piston 10 is provided on the inside with a bevel 14 so that through openings 16 of the contact tube 1 remain free even when the switch is switched on.
  • the contact piece 5 is also provided with openings 18.
  • the entire electrical switch is housed in a porcelain insulator 21 in a known manner.
  • the switch according to the invention works in the following way: As a result of actuation by the drive, not shown, the drive cylinder 6 is moved in the direction of arrow 22; thus also moves the suction piston 7 attached to it and, via the connecting rod 9, the pressure piston 10 in the direction of arrow 22, taking along the switching tube 5, which is also rigidly coupled to the drive cylinder 6.
  • the pressure piston 10 moves, not only is it used for insulation within the porcelain insulator 21 located insulating gas compressed inside the pressure cylinder 11, but at the same time sucked through the through openings 16 from the pressure piston 10 insulating gas from the inside of the contact tube 1, the flow obstacle 19 ensuring that not too much insulating gas flows in from the low-pressure space of the switch.
  • the switch tube 5 with its openings 18 reaches the area of the holes 17 of the guide tube 4, so that 4 insulating gas is also sucked out of the interior of the guide tube 4 by the suction piston 7 and thus a negative pressure is also generated on this side of the separating distance T. It is thus contributed to the generation of a negative pressure from both sides of the separation section T.
  • the suction cylinder 8 cannot be closed off by a fixed base, but by a counter-piston 23 on its side facing away from the pressure cylinder 11.
  • This counter piston 23 can be connected to the drive of the switch in a manner as described in detail in DE-A-19 66 973.
  • the counter-piston 23 is consequently moved in the direction of arrow 24 during the switch-off movement and therefore causes an additional compression of the insulating gas in the interior of the suction cylinder 8 together with the suction piston 7. If there is a pressure line 25 between the interior of the suction cylinder 8 and the pressure cylinder 11, then this pressure is transmitted to the interior of the pressure cylinder 11 and causes a further pressure increase in the cylinder 11. This has an advantageous effect on the flow of extinguishing agent and on the dielectric strength of the switching path Disconnect the switching tube 5 from the extinguishing nozzle 2 of the contact tube 1.
