Definitions

  • the present invention relates to a hybrid high-voltage circuit breaker.
  • Such a hybrid circuit breaker comprises for each pole a dielectric gas breaking chamber, for example SF6 under pressure, the fixed contact is connected to a first terminal of the network and connected in series with a switch supporting the dU / dt voltage recovery transient and whose fixed contact is connected to a second terminal of the network.
  • This switch is often a vacuum bulb.
  • FIG. US Patent 4,458,119 Such a hybrid circuit breaker in a metal envelope, said to be commonly shielded, is described in FIG. US Patent 4,458,119 where break chamber and bulb are connected in series and aligned.
  • the movable contacts of the chamber and the bulb are connected to actuating means between an open position and a closed position by means of a single command.
  • These actuating means comprise a set of rods ensuring the opening of the contacts of the vacuum bulb before that of the contacts of the gas shutoff chamber. This offset is generally of the order of a few milliseconds. It is caused by the trajectory of the shorter moving contact on the vacuum bulb than on the breaking chamber.
  • This type of hybrid circuit breaker poses the following technical problems.
  • the gas-cutting chamber and the vacuum interrupter along two inclined axes, the movable contact of the interrupting chamber being extended by a longitudinal drive arrangement on which is arranged in permanent contact an element connected to the movable contact of the vacuum interrupter, the single command requesting the movable contact of the translation cleavage chamber along the first axis and the length and shape of the drive arrangement ensuring a synchronization between moving the movable contacts from a closed position to an open position of the moving contacts and vice versa.
  • the interrupting chamber and the vacuum interrupter remain in the open position. Now in this position, the set of moving contacts and the charged parts which their are integral forming a so-called floating potential behaving as a capacitor and likely to cause partial discharges may degrade the circuit breaker, for example in insulating parts under tension, especially when the voltage across the circuit breaker is important. This can lead to reboots, mainly due to the small distance between the contacts of the vacuum interrupter.
  • the invention proposes a hybrid circuit breaker comprising for each pole a dielectric gas breaking chamber comprising a first contact and a second movable contact disposed longitudinally at a first axis and whose first contact is connected to a first terminal of the network, this breaking chamber being connected in series with a vacuum bulb having a fixed contact and a movable contact disposed longitudinally to a second axis and whose fixed contact is connected to a second terminal of the network, actuating means ensuring by a single control the movement between an open position and a closed position of said movable contacts, characterized in that said actuating means comprise a reclosing arrangement of the movable contact of the vacuum interrupter, ensuring this reclosing by said single command before the opening position of the movable contact of said breaking chamber.
  • An important feature of the invention is that this reclosing of the vacuum bulb is performed by the same single command as the opening and closing of the contacts thus allowing a particularly light control arrangement. This results in a limited number of parts and a lower cost and lower assembly time.
  • said actuating means comprise an arrangement for moving the moving contact of said breaking chamber over a distance greater than the distance between the contacts of the interrupting chamber in the open position.
  • the contacts of the interrupting chamber are spaced a distance greater than that required for the circuit breaker function and the interrupting chamber can fill after this open position a disconnector function.
  • the hybrid circuit breaker comprises an arrangement for grounding the second terminal actuated by said single command.
  • This other feature of the invention further increases the ease of control, automatic and synchronized, of the hybrid circuit breaker.
  • the grounding arrangement is a separate envelope element provided with a specific control.
  • the circuit breaker according to the invention is optimized for the materials used and therefore the cost.
  • said two axes are substantially perpendicular

  • said longitudinal drive arrangement is formed by a slide having two running surfaces parallel to each other, said element connected to the movable contact of the vacuum interrupter being disposed in said slideway and permanently in contact with it. one or the other of the two running surfaces.
  • said longitudinal driving arrangement is formed by a cam, said element connected to the moving contact of the vacuum bottle being able to press against the rolling surface of said cam on the side opposite to that of the bulb when activating the control of the operating means of the hybrid circuit breaker.
  • said slide or said cam comprises a first section parallel to the first axis disposed on the side of said extended control on the side of the movable contact of the cutting chamber by a second section inclined in the opposite direction to the movable contact of the vacuum bulb itself extended by a third section parallel to the first axis on the side of the moving contact of the breaking chamber, the latter section being extended a fourth section inclined towards the movable contact of the vacuum bulb itself extended by a fifth section parallel to the first axis on the side of the movable contact of the interrupting chamber.
  • Said fifth section provides the reclosing function of the vacuum bulb.
  • said fifth section is longer than the distance between the contacts of the interrupting chamber at the end of the open position.
  • said grounding arrangement is driven by a connecting rod of which a fixed element is disposed in said slideway or on the rolling surface of said cam, the translation of this rod at the passage of this integral element in the second section ensuring the displacement of a contact electrically connected to said vacuum bulb in a contact member connected to the ground.
  • said grounding arrangement consists of a contact disposed at the end of the longitudinal groove arrangement on the control side and coming into a contact member connected to the earth at the end of the opening stroke of the movable contact of the interrupting chamber.
  • a closing spring mechanical spring arrangement is disposed substantially along the second axis.
  • Said spring of said closing pressure arrangement is advantageously disposed outside a housing which encloses said longitudinal drive arrangement.
