Definitions

  • the invention is based on a compressed gas switch according to the first part of patent claim 1.
  • Such a switch has been proposed in Swiss patent application 4015 / 84-0.
  • This switch has an insulating gas-filled housing, in which two switching elements which are movable along an axis relative to one another and each have an erosion contact and a rated current contact are arranged.
  • the overall length which extends in the direction of movement of the switching pieces, is kept small by providing power connections which run into the housing transversely to this direction of movement and form loops in the interior of the housing.
  • this switch requires a comparatively large drive energy when it is switched off, since the rated current and the erosion contacts are moved simultaneously.
  • the invention as characterized in the claims solves the problem of specifying a gas pressure switch of the generic type, in which a comparatively weak drive can be used despite a high switching capacity and a compact design.
  • the pressure gas switch according to the invention is characterized essentially by the fact that the suitable arrangement and design of its contacts and its drive, when it is switched off, actuates its rated current contacts and its erosion contacts in a staggered manner, thus reducing the drive energy.
  • 1 denotes a housing made of insulating material, which is filled with an insulating gas, such as sulfur hexafluoride at a pressure of 4 to 6 bar, and is sealed off by a grounded metal cover 2.
  • an insulating gas such as sulfur hexafluoride at a pressure of 4 to 6 bar
  • bushings 3 and 4 are provided, through which a common power connection 5 or 6 for a movable nominal current contact 7 and a movable erosion contact 8 or a fixed nominal current contact 9 and a fixed erosion contact 10 into the interior of the housing 1 are performed.
  • the power connection 5 is via a rotary contact 11 formed, for example, from lamellae with the movable nominal current contact 7, which is rotatably mounted in the power connection 5, and via a likewise, for example, from lamellae formed sliding contact 12 with the burnable along an axis 13 burn contact 8 connected in an electrically conductive manner.
  • the fixed nominal current contact 9 is attached to the power connection 6.
  • the power connection 6 is also guided into a switching chamber 14 and connected in an electrically conductive manner to the fixed erosion contact 10 located in this switching chamber.
  • the power connection 5 is manufactured together with the bearing points for the rotary contact 11 and the movable erosion contact 8 from a single copper compact.
  • the power connection 6 is also made from a single copper compact.
  • a drive lever 16 On a drive shaft 15 which is rotatably mounted in a bulge of the grounded metal cover 2 and is guided perpendicular to the axis 13, a drive lever 16 is fastened to which two insulating rods 17 and 18 of approximately the same size are articulated.
  • the insulating rod i 7 is articulated on the end of the movable erosion contact 8 facing away from the fixed erosion contact 10, whereas the insulating material rod 18 is articulated in the part of the movable nominal current contact 7 facing the fixed nominal current contact 9.
  • the movable nominal current contact 7 is formed by a double knife, which consists of two parallel and curved knife contacts.
  • the blade contacts are held at a distance from one another at the rotary contact 11 and at the pivot point 19 and are in the switched-on position, the insulating wall of the switching chamber 14 engages behind the fixed nominal current contact 9. Between the two knife contacts there is sufficient space for the current connection 5 carrying the knife contacts and for an unimpeded movement of the two insulating rods 17 and 18, which are also arranged between the two knife contacts.
  • a drive crank 20 formed from the drive shaft 15 and the drive lever 16 forms, together with the insulating rod 17 and the erosion contact 8 which can be displaced in the direction of the axis 13, a push crank which is located on a dash-dotted straight line in a dead center 21.
  • a crank rocker is formed from the drive crank 20, the insulating rod 18 and the rotatable nominal current contact 7, which is located on a further dash-dotted straight line in a dead center 22.
  • the drive crank 20 When the compressed gas switch according to the invention is switched off, the drive crank 20 is rotated counterclockwise by a drive (not shown). If the insulating rods 17 and 18 now so articulated on the driving crank 20 that in the ON state, the thrust crank acting on the movable Abbrandkonakt 8 is rotated by an angle of approximately 10 to 30 0 over the dead-center position 21 addition, and the moving rated-current contact 7 Acting crank arm is essentially in the dead position 22, the movable erosion contact 8 moved into the fixed erosion contact 10 in the switched-on state will change its position only insignificantly as long as the drive crank 20 only reaches the position shown in FIG and the drive shaft 15 moreover at a comparatively small distance from the axis compared to the lengths of the insulating rods 17, 18 13 is mounted in the bulge of the metal cover 2.
  • crank arm which is in the dead center position 22 in the switched-on state, has already moved the movable nominal current contact 7 in the direction of the arrow by the time indicated in FIG. 2 so that the nominal current contacts 7 and 9 begin to separate and the one to be disconnected from the power connection 5 via the rotary contact 11, the movable nominal current contact 7, the fixed nominal current contact 9 to the current connection 6 commutates the current flowing from the current connection 5, the sliding contact 12, the movable erosion contact 8, the fixed erosion contact 10 and the current connection 6.
  • the erosion contacts 8, 10 When the drive crank 20 is turned further counterclockwise, the erosion contacts 8, 10 then open and an arc is drawn between the erosion contacts 8, 10, which is subsequently blown with insulating gas.
  • a major advantage of the pressure gas switch described above is that due to the suitable arrangement and design of its contacts and its drive when switched off, the actuation of its rated current and its erosion contacts is staggered over time, a reduction in the immersion depth of the movable erosion contact 8 in the fixed erosion contact 10 and thus a considerable saving in drive energy is achieved. At the same time, the stroke of the movable erosion contact 8 is considerably reduced, since a considerable movement of this contact in the switch-off direction can only take place after the nominal current contacts 7, 9 have been opened. For this reason and since the movable nominal current contact 7, which is designed as a curved double knife, engages behind the switching chamber 14, the pressure gas switch according to the invention is extremely compact and space-saving.
  • the curved shape of the movable nominal current contact 7 not only saves space because of the reduction in its predetermined distance from the grounded metal cover 2 in the switched-off state, but at the same time ensures that this contact can be reliably moved in and out of the fixed nominal current contact 9. Since the movable nominal current contact 7 is moved towards or away from the fixed nominal current contact 9 in the direction of flow of the current to be switched, disturbing transverse forces and tilting moments are eliminated on the movable nominal current contact 7. It is also advantageous that the Nominal current contacts 7, 9 are retracted deeply into one another in the switched-on state, which enables good contact-making. Since this retraction is also essentially in a dead position of the drive, tolerance problems are eliminated.
