Definitions

  • the invention relates to a gas-insulated multipolar rotary switch, in particular for an electrical panel of a medium-voltage distribution station, having an insulating envelope filled with gas of high dielectric strength, and containing by pole a mounted double movable contact. on an insulating shaft, said movable contact being in the form of a knife with three positions cooperating in rotation with a plurality of fixed contacts staggered angularly in the same plane, along the internal wall of the envelope, to occupy a first closed position ensuring the electrical connection between an input terminal to which an incoming conductor is connected, and an output terminal to which an outgoing conductor is connected, a second open position ensuring separation between the two conductors and a third earthing position of one of the conductors.
  • Document EP-A-199,044 describes a three-position rotary switch comprising an insulating enclosure having three fixed contacts cooperating with a double movable contact in the form of a knife. In the open position, the movable contact does not come into engagement with the fixed contacts, and is isolated from the ground. The sectioning and ground ring functions are not fulfilled.
  • the switching shaft carries a compression fin, serving to support the knife of each pole.
  • the fin is made of insulating material.
  • the document FR-A-1,279,475 describes a medium-voltage cell with a three-phase rotary switch with air isolation, constituted by rotary bushings.
  • the movable contact is earthed in the intermediate open position, but the switch does not have a guard ring or a compression piston.
  • the document CH-390.346 relates to a high voltage disconnector for an armored substation. It has a rotary contact with two positions, with earthing of the movable contact in the open position. A metal plate is associated with the movable contact, but this plate does not act as a piston. Earthing of the phase conductors associated with the station's fixed contacts is excluded.
  • the object of the invention consists in making a rotary switch with gas isolation having a reduced bulk and good dielectric strength.
  • any operation on the equipment downstream of the switch for example the test of the feeder conductor, can thus be carried out safely, thanks to the presence of the metal screen grounded when the contact is in the second position.
  • the guard ring function is removed in the first closed position, because the screen is then isolated from the ground.
  • the screen In addition to its function as a guard ring, the screen also plays the role of a rotary piston for compressing the gas in piston chambers of the envelope.
  • the blowing means communicate with this chamber to ensure the extinction of the arc drawn between the contacts, when the knife passes from the first closed position to the second open position.
  • a pole of a rotary switch 10 for a switchboard of a three-phase medium voltage distribution station with gas isolation is housed in a cylindrical casing 12, filled with gas of high dielectric strength, in particular of sulfur hexafluoride SF 6.
  • the casing 12 is made of insulating material, and comprises on its internal periphery a series of five fixed contacts 14 to 22 carried by radial bushings.
  • the fixed contacts 14 to 22 are arranged in the transverse median plane of the casing 12 with a predetermined angular offset, and cooperate with a double movable contact 24 in the form of a rotary knife with three positions.
  • the first fixed contact 14 is connected externally to an incoming conductor 26, while the third fixed contact 18, diametrically opposite, is connected to a starting conductor 28.
  • the fourth and fifth fixed contacts 20, 22 are interconnected by a earth connection 30.
  • the second fixed contact 16, diametrically opposite to the fifth fixed contact 22, is located between the first and third fixed contacts 14, 18, and is connected to the starting conductor 28 by an electrical connection 32.
  • a longitudinal shaft 34 for driving in rotation the movable contact 24, is arranged coaxially inside the cylindrical envelope 12, and is made of insulating material.
  • the knife of the double movable contact 24 is secured to a metallic radial screen 36 extending orthogonally to the longitudinal shaft 34 and to the transverse median plane of the switch 10.
  • the screen 36 is fixed laterally to two electrodes 38, 40, annulars encircling the two opposite ends of the insulating shaft 34.
  • the movable contact knife 24 comprises a pair of parallel contact blades 24 a, 24 b, separated from each other by a predetermined axial interval l (see FIG. 5).
  • the two blades 24 a, 24 b, are elastically biased towards one another, and the presence of the interval l allows the elastic insertion of the two diametrically opposite zones of interruption of the knife with the fixed contacts 14 to 22 corresponding, during the rotation of the shaft 34 between the three positions.
  • the dimension of the metallic screen 36 in the diametrical direction may be less than that of the knife, so as to leave a radial clearance (see FIG. 3) between the internal wall of the envelope 12 and the edge of the screen 36.
  • the thickness of the radial clearance is generally less than 5 millimeters.
  • the casing 12 further comprises two fixed partitions 42, 44 cooperating with the movable assembly to form a device for compressing the insulating gas, contained in the two chambers (46 a, 46 b; 48 a, 48 b) which can be pistoned, formed in the interior volume of the envelope 12.
  • the compression device is associated with blowing means (not shown), intended to extinguish the arc drawn between the contacts, when the knife passes from one position to the other .
  • the actuation of the rotary shaft 34 in the trigonometric direction causes the opening of the switch by angular separation of the knife with the fixed contacts 14, 18.
  • the opening stroke of the movable contact 24 corresponds approximately to 60 degrees, and one of the knife contact zones comes into engagement with the fourth fixed contact 20 connected to the ground.
  • the mobile assembly forms, in this second open position, an integrated guard ring, composed of the metallic screen 36, the movable contact 24 and the two electrodes 38, 40.
  • the insertion of the metallic screen 36 on the leakage line between the input and output terminals of the switch 10 prevents any break in the insulation between these terminals, following a dangerous path along the internal wall of the insulating jacket 12, and the tree 34.
  • the test operation of the latter is carried out in the open position (FIG. 3) by injection of a test current on one of the fixed contacts 16 or 18, or on a special outlet of the outgoing conductor 28.
  • the cable test is thus carried out safely, when the screen 36 and the knife are connected to earth.
  • the metal screen 36 acts as a rotary gas compression piston in the chambers 46 a, 46 b; 48 a, 48 b.
  • the gas compression effect occurs in the two directions of rotation of the movable contact 24, and is advantageously used for blowing the arc drawn during the opening phase of the switch 10, after passing from the first position (figure 2) to the second position (figure 3).
  • the rotary switch 10 provides a sectioning function in the second open position, thanks to the presence of the screen 36 grounded, allowing to maintain correct insulation between the input and output terminals .
  • the guard ring function is eliminated in the first closed position (FIG. 2) of the rotary switch 10, because the screen 36 is isolated from the ground.
  • the insulating casing 12 of the rotary switch 10 comprises two end pieces 50, 52, of ends made of insulating material, allowing a reduction in the size of the metallic screen 36 in the longitudinal direction.
  • FIG. 7 shows the outright elimination of the screen 36, thanks to larger end pieces 50, 52, delimiting a narrow axial interval for the passage of the single movable contact 24 to two parallel blades.
  • the guard ring is then constituted by the movable contact 24 in the form of a knife.
  • the rotary gas compression piston is formed by a separate part from the metallic screen 36.
  • the invention has been described in relation to an envelope 12 containing a single switch pole, but it is clear that it applies to a three-phase switch in which the poles are aligned along the longitudinal axis of the shaft 34
  • the poles can be housed in a common insulating envelope, or in independent envelopes attached to each other.
  • the casing 12 of each pole of the rotary switch 10 is made of metallic material, the fixed contacts 14 to 22 then being supported by insulating bushings.
  • FIG. 8 shows an application of the invention in a medium-voltage distribution cell for a three-phase network enclosing a circuit breaker 60 having a first terminal connected to the busbar 62 by a first rotary switch 10 of the type described above, and a second terminal connected to the start 64 via a second rotary switch 10.
  • FIG. 9 represents another application of the invention in a cell for coupling two busbars 62, 66, elementary of a three-phase network RST, by means of a circuit breaker 60.
  • the first busbar 60 is connected to the circuit breaker 60 by a rotary switch 10
  • the second busbar 66 is connected to the circuit breaker by a second rotary switch 10 with three positions.
  • the two switches 10 have a structure identical to that described with reference to FIGS. 1 to 4.
  • FIG. 10 shows a plan view of FIGS. 8 and 9, in which the superposition of the rotary switches 10 of the three phases appears, in a vertical direction parallel to the alignment of the poles of the circuit breaker 60.
  • the grouping in column of the six poles d switches 10 on the same shaft line facilitates the mechanical control of the cell.
  • the invention also applies to an eccentric rotation switch of the movable knife.
  • the extinction of the arc drawn during the opening phase of the rotary switch can occur by means of a permanent magnet suitably positioned inside the envelope 12.
  • the action of the magnetic field of the magnet on the arc causes the latter to rotate and rapidly extinguish.
