  • the piston is semi-mobile and means are provided for immobilizing the piston during a first part of the displacement of the contact assembly movable between closed position and position opening and means for axially moving the piston with the moving contact assembly for a second part of this same movement of the movable contact assembly.
  • the means for axially moving the piston consists of a drive member integral with the contact assembly mobile which causes a stop integral with the piston during the second part of the displacement of the contact assembly mobile, this stop being arranged on the path of the member training.
  • the piston is connected to a third tube provided with at least one light in which a finger integral with the first tube and which extends radially relative to it towards the second tube.
  • the way to immobilize the piston is constituted a spring disposed between the drive member and the piston and by a fixed retainer cooperating with the piston.
  • the object of the invention is to provide a circuit breaker with low operating energy and therefore inexpensive, the blowing of weak currents is done by autocompression and blowing strong currents by thermal expansion.
  • the first means include the fixed piston cooperating with the first tube on a certain stroke x and the second means include a means of evacuating the gas contained in the compression chamber out of it acting once the race x finished.
  • the course x is equal to the course of the movable arcing contact on the fixed arcing contact before their separation.
  • the first tube is closed frontally by a wall arranged at a certain distance d1 from the crown on the side opposite the arcing contacts.
  • the second means comprise at least a light made in the first tube, arranged on the side crown opposite to arcing contacts, length greater than the thickness of the piston and with the most distant from the crown is at a distance d from the crown, the distance d being less than or equal to the distance d1 and the side opposite the movable arcing contact of the piston being distant by a length equal to d + x from the crown in closed position.
  • the edge of the light closest to the crown is at a distance d2 from the upper piston or equal to the total travel of the movable arcing contact, when the circuit breaker is in the closed position.
  • the light is adjacent to said wall, the distance d being equal to the distance d1.

  • the light may consist of a set of orifices made in the first tube.
  • the gas contained in the compression is vented out of it inside of the envelope, once the race x is finished and to do this, advantageously, the piston is carried by a fixed tube coaxial with said first and second tubes and pierced with at least a gas discharge orifice, located near its end opposite to said contacts.
  • Figure 1 is a longitudinal sectional view of a circuit breaker according to the invention in the closed position.
  • Figures 2 and 3 are sectional views longitudinal of a circuit breaker according to the invention in intermediate positions between the closed position and the open position.
  • Figure 4 is a longitudinal sectional view of a circuit breaker according to the invention in the open position.
  • Figures 5 to 7 are views in longitudinal section of a circuit breaker according to the invention in positions of closing, intermediate and opening, according to a variant of achievement.
  • the circuit breaker shown in the figures includes, conventionally, an insulating jacket 1 filled with a gas dielectric under pressure, two arcing contacts 3A, 7A cooperating with each other, at least one of which is part of a movable contact assembly integral with a operation 6 and adapted to be moved axially in envelope 1 between a closed position and a open position, the movable contact assembly being constituted by a first tube 7 carrying at its end the movable arcing contact 7A and a second tube 8 coaxial with first tube 7 to delimit, on either side of a ring 9 connecting the first and second tubes, a expansion chamber 17 at constant volume closed by a nozzle blowing 10 and a compression chamber 18 communicating via a one-way valve 2 with the expansion chamber and closed by a piston 11.
  • the circuit breaker may also have a permanent contact 14 cooperating with the end 8A of the second tube 8 forming permanent mobile contact.
  • the first means are provided of compression of the gas in the compression chamber 18 during a first part of the movement of the assembly of movable contact between the closed position and the open position and second decompression means gas in the compression chamber 18 for one second part of this same displacement of the contact assembly mobile.
  • the first means include the fixed piston 11 cooperating with the first tube 7 over a certain stroke x when moving the mobile assembly and the latter means include means for discharging the contained gas in the compression chamber 18 outside of it acting once the race x has ended.
  • the stroke x is equal to the stroke of the arcing contact movable 7A on the fixed arcing contact 3A before their separation.
  • the first tube 7 is closed frontally by a wall 5 arranged at a certain distance d1 from the crown 9 on the side thereof opposite the arcing contacts.
  • the second means include at least one light made in the first tube 7, disposed on the side of the ring 9 opposite to the arcing contacts, of greater length at the thickness of the piston 11 and the edge of which is furthest from crown 9 is at a distance d from crown 9, the distance d being equal to the distance dl, but being able to be possibly lower, and the face opposite to the contact movable arc 7A of the piston 11 being spaced a length equal to d + x of the crown 9 in the closed position.
