Definitions

  • a known circuit breaker of the kind mentioned (publication US-A-3,671,696) has arcing contacts housed in a vacuum interrupter interposed between the inlet and outlet bushings.
  • a disconnector is connected in parallel with the vacuum interrupter and the assembly is arranged in a box filled with air.
  • the main circuit containing the disconnector is removed from the auxiliary circuit for housing the vacuum interrupter and forms a reactance loop significantly greater than that of the loop of the auxiliary circuit, preventing rapid switching from the main circuit to the auxiliary circuit. when opening the disconnector.
  • the main circuit is longer than the auxiliary circuit, which increases the resistance and overheating of the circuit breaker and affects the distribution of current between the two circuits.
  • the switch is placed in the air and the separation distance between the open contacts must be sufficient for the insulation. This results in a large opening travel and a significant drive control energy.
  • the size of the cabinet is a multiple of that of the vacuum interrupter.
  • the object of the present invention is to remedy these drawbacks and to allow the production of a self-blowing circuit breaker with quasi-independent main and auxiliary circuits, in which the reactances of these circuits are substantially equal in order to facilitate rapid switching of the current.
  • the circuit breaker is characterized in that it is housed in a sealed insulating envelope, filled with an insulating gas with high dielectric strength, in particular sulfur hexafluoride, surrounding said main contacts and said arcing contacts, and that the main circuit is connected directly to said terminals by extending along a path directly adjacent and shorter than that of the auxiliary circuit between said terminals inside said envelope.
  • an insulating gas with high dielectric strength in particular sulfur hexafluoride
  • the invention starts from the observation of the interest of the separation of the functions of conduction of the permanent current and that of cut of the current, in particular of fault.
  • the main circuit provides the first function and the length, and the cross section of the conductors and the structure of the contacts are chosen for this purpose.
  • the second function is provided by the auxiliary circuit on which the current is switched when the main contacts are separated.
  • Self-blowing circuit breakers are known (publication US-A-3257532, publication FR-A-1458 334), provided with arcing contacts and main contacts arranged circumferentially around the arcing contacts.
  • the reactances of the two circuits are almost identical, which facilitates switching, but risks of interaction of the cuts are not excluded, the moving part carries the two moving contacts and the inertia of the assembly is opposed to a quick order.
  • a pole of the self-blowing circuit breaker comprises a sealed casing 10 filled with insulating gas with high dielectric strength, in particular sulfur hexafluoride.
  • the casing 10 made of molded insulating material, is closed by a cover 12 and serves as a housing for a main circuit 14 for passing the nominal current, an auxiliary circuit 16 for shunting the main circuit for breaking the arc, a mechanism control 18 of the movable assembly for the successive opening of the main 14 and auxiliary 16 circuits, and two terminals 20, 22 for supplying current constituted by crossings of the wall of the insulating casing 10 offset longitudinally.
  • the main circuit 14 comprises a movable main contact 24 provided with a plurality of pairs of fingers 26a, 26b, 26c, 26d ..., articulated on a fixed axis 28 secured to a first conductor 30 for connection with the lower terminal 22
  • An elastic means, in particular a compression spring 32 is associated with each pair to urge the corresponding fingers towards one another, so as to form a clamp cooperating in the closed position of the main circuit 14 with an extension 34, 36 a fixed main contact 38.
  • the latter is electrically connected to the upper terminal 20 by a second connecting conductor 40.
  • the tightening of the fingers 26a, 26b; 26c, 26d on the corresponding extension 34, 36 is reinforced by the electrodynamic attraction exerted between said fingers of each pair traversed by currents of the same direction.
  • the auxiliary circuit 16 connected in parallel to the main circuit 14 inside the casing 10, comprises aligned arcing contacts, one of which is fixed 42 is connected to the upper terminal 20, and the other of which is movable 44 is integral with a conductive rod 46 coupled to a control crank 48.
  • the external actuation mechanism transmits the movement to the crank 48 by means of a rotary transmission shaft 50 passing through the wall of the casing 10 with the interposition of a sealed bearing 52.
  • An electrical connection with relative movement, in particular a flexible shunt conductor 54 is arranged in the auxiliary circuit 16 between the rod 46 and the lower terminal 22.
  • An intermediate partition 56 parallel to the bottom 58 and to the cover 12 of the pole, divides the internal space of the envelope 10 into two separate compartments 60, 62 superimposed.
  • the lower compartment 60 contains the main contacts 24, 38, and the upper compartment 62 contains the cut-off interval 64 formed between the arcing contacts 42, 44 in the separate position.
  • the physical separation between the main contact interruption zone and the cut-off interval 64 avoids any risk of re-striking the arc in the vicinity of said zone as a result of polluted hot gases coming from the cut.
  • the current supply terminals 20, 22 form bypass nodes of the two main 14 and auxiliary 16 circuits, and the shunt conductor 54 is traversed exclusively by the fault current.
  • the two circuits 14, 16 extend parallel to the interior of the envelope 10 with a slight transverse offset, so as to form a loop of low reactance, the circuit 14 following the shortest path.
  • the self-blowing device 66 of a type well known to specialists is arranged in the upper compartment 62 and comprises a movable piston 68 secured to the rod 46.
  • the piston 68 carries a blowing nozzle 70 coaxially surrounding the arcing contacts 42 , 44 in the closed position, and cooperates with limited sliding with a fixed cylinder 72 to delimit a pistonable volume 74 for compressing the insulating gas.
  • a flow of blowing gas is expelled through openings 76 provided in the piston 68 in the convergent of the nozzle 70, towards the cut-off interval 64 for the extinction of the arc.
  • the actuation mechanism comprises a kinematic link 78 mechanically connecting the rod 46 of the arcing contact 44 to the main movable contact 24 to transform the rectilinear movement of the rod 46 into a pivoting movement of the contact 24 during the stroke of the mobile equipment of the circuit breaker.
  • This kinematic link 78 is provided with a transmission lever 80 secured to the fingers 26 and cooperating at its opposite end with a drive pin 82 attached to the rod 46.
  • the stroke of the clamps of the main movable contact 24 is different and in particular shorter than that of the movable arcing contact 44.
  • the actuation mechanism After detecting a fault current on the network to be protected, the actuation mechanism causes the downward axial translation (in the direction of the arrow F) of the rod 46 and the pivoting of the lever 80 clockwise causing the opening of the main contacts 24, 38, and the switching of the current in the auxiliary shunt circuit 16.
  • the fault current path is then as follows: upper terminal 20, fixed arcing contact 42, movable arcing contact 44, rod 46, shunt conductor 54, conductor 30, lower terminal 22.
  • the crew's continued race mobile causes the separation of the arcing contacts 42, 44 and the blowing of extinguishing gas from the arcing.
  • the cutting zone 64 is physically separated from the main contacts 38, 24, in particular by the partition 56 and prevents any re-ignition of the arc between said main contacts.
  • the arcing contacts 42, 44 can close first or, on the contrary, after the main contacts 24, 38 close, depending on the desired operating conditions.
  • the control device is of course arranged accordingly.
  • the main movable contact 24 could also be arranged in the form of a bridge actuated in radial or axial translation by the kinematic link 78 during the axial displacement of the rod 46.
  • the invention is applicable to a circuit breaker with pneumatic self-blowing, with magnetic self-blowing or with combined magnetic and pneumatic self-blowing.
