Definitions

  • the present invention relates to a circuit breaker comprising, in an enclosure filled with dielectric gas, in particular SF6, a first arcing contact connected to a first socket, a second arcing contact connected to a second socket and movable in a fixed cylinder, where it forms with a piston a compression chamber, the first arcing contact being movable and the circuit breaker comprising means for actuating this first arcing contact in the direction opposite to that of the displacement of the second contact.
  • dielectric gas in particular SF6
  • a first arcing contact connected to a first socket
  • a second arcing contact connected to a second socket and movable in a fixed cylinder, where it forms with a piston a compression chamber
  • the first arcing contact being movable
  • the circuit breaker comprising means for actuating this first arcing contact in the direction opposite to that of the displacement of the second contact.
  • the first contact and the piston are fixed, the separation of the contacts and the compression of the dielectric gas in the compression chamber being done by simple displacement of the second movable contact.
  • French patent FR-A-2 491 675 discloses a breaking device with a first type of displacement, that is to say the contacts of which are moved in opposite directions, in order to increase the speed of separation of the contacts without increasing the speed of the moving contact.
  • the actuating means consist of an arrangement of tie rods and connecting rods.
  • French patent FR-A-2 320 626 describes a circuit breaker with a second type of displacement, that is to say with piston and contact movable by means of rods, the fixed contact being integral with the cylinder forming blowing chamber.
  • a high speed of separation of the contacts and a large stroke to hold the voltage are sought to cut the capacitive currents.
  • a high blowing pressure and a rapid pressure build-up are required.
  • the object of the invention is to allow correct cutting of these types of current by combining the two types of movement specified above, while using the lowest possible operating energy thanks to a single rotary control.
  • the heavy piece which is the second contact
  • the cylinder is fixed.
  • the light part, which constitutes the first contact, can have a relatively high speed and stroke.
  • the circuit breaker can be filled with dielectric gas at low pressure, which improves its resistance to very cold weather.
  • the invention results in low wear of the contacts and low pollution of the dielectric gas.
  • the means for actuating the second contact and the piston preferably consist of articulated levers.
  • Figure 1 is a longitudinal sectional view of a circuit breaker according to the invention, in the closed position.
  • Figure 2 is a longitudinal sectional view of the circuit breaker, in the open position.
  • Figure 3 is a longitudinal sectional view (perpendicular to the previous) of the circuit breaker, in the closed position.
  • the circuit breaker comprises in a casing 1 a first arcing contact 2 connected to a first socket 3, a second arcing contact 4 connected to a second socket 5 and movable in a fixed cylinder 6 where it forms with a piston 7 a blowing chamber 8.
  • the circuit breaker shown is with a metal casing 1 and for clarity, the permanent contacts are not shown; they can be internal or external to the envelope, in a known manner.
  • the circuit breaker can be intended for high or medium voltage.
  • the first arcing contact 2 and the piston 7 are movable by means of actuation means ensuring the displacement of the first arcing contact 2 in the opposite direction to that of the displacement of the second contact 4 and the displacement of the piston 7 in the opposite direction to that of the displacement of the second contact 4.
  • these actuating means are a single control rotary shaft 9.
  • This horizontal shaft 9 disposed in the lower part of the circuit breaker, is connected in rotation with a pin 10 carrying at one of its ends a pin 11 and forming at its other end a fork supporting an axis 12.
  • tie rods 16 On the levers 13, near their connection with the pin 11, two horizontal axes 15 are fixed on which two tie rods 16 turn, made of insulating material, connected at their upper end by a horizontal rod 17, made of insulating material, driving the first contact 2 via an arrangement described below.
  • These tie rods 16 working only in traction are of simple section, for example round.
  • a rotary lever 18 of insulating material is mounted on the axis 12, and is mounted a rotary lever 18, of insulating material, linked to a horizontal axis 21 integral with the second contact 4.
  • the upper end of the first contact 2 has an annular flange housed in a hollow cylinder 19 integral with the first socket 3.
  • a spring 20 bearing between this flange and a lower edge of the cylinder 19 pushes the contact 2 upwards.
  • the rod 17 passes through two oblong slots in the cylinder 19 and rests on the upper end of the first contact 2.
  • the levers 13 are, on the other hand, in the low position, pulling the piston 7 in the low position near the lower end of the cylinder 6.
  • the compression volume 8 is then maximum.
  • the tie rods 16 are consequently also in the low position, the rod 17 pushing the first contact 2 downwards against the stress of the spring 20.
