Definitions

  • a mechanism of the kind mentioned is described in document EP-A-222,645 of the applicant.
  • the electrodynamic resistance of the circuit breaker results from the action of the contact pressure springs on the multiple fingers, and of the compensated contacts, the hinge axis of which is subjected to significant mechanical reactions.
  • the mechanism is capable of absorbing these reactions for a maximum threshold of short-circuit current. Beyond this threshold, the reactions are liable to damage certain axes or transmission members of the mechanism, and risk increasing the tripping force at the level of the stage comprising the hook, the opening pawl, and the lock. Intervention of the trigger instantaneous requires a response time of the order of 10 ms to obtain tripping of the mechanism, which is too long if the circuit breaker performance must satisfy high electrodynamic resistance, and a breaking capacity greater than 130kA.
  • the object of the invention consists in making a circuit breaker with high electrodynamic resistance, and with high breaking capacity, requiring a reduced tripping force, and a short tripping time when a large short-circuit current appears. .
  • the mechanism according to the invention is characterized in that the opening pawl includes disengageable actuation means causing the lock to self-unlock in the presence of a short-circuit current exceeding a calibration threshold defined by elastic means, said self-unlocking being controlled from a mechanical reaction generated by the electrodynamic compensation effect, and causing an ultra-rapid rotation of the lock to unlock the opening pawl before the intervention of the triggering member.
  • the opening pawl comprises a retaining lever provided with a spout intended to hang on the latch in the locked position and at least one support flange of a roller cooperating with a surface d support of the trigger hook, said elastic means being arranged between the retaining lever and the flange, allowing a relative movement suitable for self-unlocking of the lock after exceeding the calibration threshold.
  • the retaining lever is articulated on the pivot axis of the opening pawl, the flange comprising an operating ramp intended to rotate the lock to ensure said self-unlocking.
  • a mechanism 10 for controlling a multipole circuit breaker is carried by a chassis 12, and includes a toggle device 14 having a pair of transmission rods 16, 18 articulated on a pivot axis 20.
  • the lower link 16 is mechanically coupled to a switching bar 22. made of insulating material extending perpendicular to the flanges of the chassis 12.
  • the switching bar 22 is common to all of the poles, and is constituted by a shaft mounted for rotation between an open position and a closed position of the circuit breaker contacts.
  • the circuit breaker is of the high current type, and having a high electrodynamic resistance.
  • each pole there is a connecting rod 24 which connects a crank 25 of the bar 22 to an insulating cage 26 for supporting the movable contact 28.
  • the movable contact 28 cooperates with a fixed contact 30 in the closed position, and is connected by a braid 32 to a first connection pad 34.
  • the fixed contact 30 is carried directly by the second connection pad 36.
  • a contact pressure spring 38 is arranged between the cage 26 and the upper face of each movable contact 28 .
  • the cage 26 is pivotally mounted around a first axis 40 between the closing position and the opening position, and the movable contact 28 comprises a plurality of parallel fingers articulated on a second axis 42 of the cage 26.
  • the toggle joint device 14 is associated with a trigger hook 44 mounted with limited tilting on a main axis 46 between an armed position and a triggered position.
  • the main axis 46 is integral with the chassis 12, and one of the ends of the hook 44 is articulated to the upper link 18 by an axis 48, while the other opposite end cooperates with an opening pawl 50.
  • An opening spring 52 is anchored between a lug 54 of the bar 22, and a fixed cleat 56 of the chassis 12, said cleat 56 being disposed above the toggle joint device 14.
  • the opening pawl 50 is formed by a lever lock 57 pivotally mounted on an axis 58, between a locked position and an unlocked position.
  • a half-moon shaped latch 60 is able to move the opening pawl 50 to the unlocked position to trigger the mechanism 10.
  • a spring 62 for returning the opening pawl 50 is located opposite the latching latch 60 relative to the axis 58, and biases the opening pawl 50 counterclockwise towards the locked position.
  • a roller 64 is formed on the locking lever 57 between the axis 58 and the latching latch 60, and cooperates in the armed position with a bearing surface 66 of the trigger hook 44.
  • the bearing surface 66 of the hook 44 has a recess in which the cylindrical roller 64 engages.
  • a return spring 68 is anchored between the axis 48 and the cleat 56 to urge the hook 44 counterclockwise towards the armed position, in which the roller 64 of the opening pawl 50 is engaged in the recess of the support surface 66.
  • L trigger 70 may be manually actuated, in particular by means of a button push-button, or automatic, in particular by a magnetothermic or electronic trigger, or by a trigger with emission sensitive to a remote control signal.
  • the opening pawl 50 is arranged in a disengageable assembly allowing the self-unlocking of the latch 60 in the presence of a short-circuit current exceeding a predetermined threshold subsequently called by the declutching threshold.
  • the contacts 28, 30 and pads 34, 36 form a U-shaped circuit, the second articulation axis 42 of the fingers of the movable contact 28 being located at one third of the distance separating the two pads 34, 36.
  • the structure of a such a circuit constitutes a system for compensating for the electrodynamic repulsion forces capable of keeping the contacts closed in the presence of a short-circuit current, and until the triggering of the mechanism 10 controlled by the triggering member 70.
  • the opening pawl 50 comprises a pair of flanges 72 for supporting the axis 58 and the roller 64 mounted for free rotation.
  • the declutching threshold is calibrated by means of two compression springs 74, 76, arranged between a guide plate 78 integral with the flanges 72, and a retaining lever 80 articulated on the axis 58.
  • the end of the retaining lever 80 is provided with a spout 82 intended to hook onto the latch 60 in the locked position of the pawl 50.
  • An end of travel stop 84 is secured to the flanges 72, and is capable of limiting the pivoting movement of the pawl 50 in the unlocked position.
  • Each flange 72 comprises an operating ramp 86 disposed in the vicinity of the spout 82 of the retaining lever 80, the inclination of the ramp 86 being chosen to cause self-unlocking of the lock 60, when the calibration threshold of the springs 74, 76 is exceeded.
  • the operation of the mechanism 10 equipped with the disengageable opening pawl 50 according to the invention is as follows:
  • the bearing surface 66 of the trigger hook 44 exerts a force F on the roller 64, and urges the opening pawl 50 to rotate clockwise around the axis 58 until hooking the spout 82 to latch 60.
  • the circuit breaker is then in a stable position for closing the contacts 30, 28.
  • the circuit breaker has a high electrodynamic resistance thanks to the electrodynamic compensation effect which tends to keep the contacts closed in the presence of an overload current.
  • This electrodynamic compensation effect results from the U-shaped structure of the electrical power circuit, the second axis 42 of articulation of the fingers of the movable contact 28 being advantageously located at one third of the distance separating the two connection pads 34, 36 from the electrical circuit. in U. This results in a torque which requests the maintenance of the contacts 28, 30 in the closed position despite the opposing necking forces.
  • the reinforcement of the contact pressure by electrodynamic effect results in a mechanical reaction, exerted on the axis 42 of the cage 26, and transmitted to the mechanism 10 and finally on the roller 64 via the hook of trigger 44.
  • This increase in the force F on the roller 64 is a function of the intensity of the current passing through the electric power circuit, and tends to rotate the opening pawl 50 clockwise when the force F is greater than the ratchet calibration threshold 50, which is defined by the springs 74, 76.
  • the spout 82 of the retaining lever 80 remains in engagement with the latch 60, but the flanges 72 of the pawl 50 begin to rotate around the axis 58 clockwise.
  • the ramps 86 of the flanges 72 of the pawl 50 cooperate with the half-moon of the latch 60, and causes its rotation in the clockwise direction F1 , so as to release the retaining spout 80, causing the opening pawl to move towards the unlocked position (FIG. 4).
  • the exhaust of the roller 64 also releases the trigger hook 44, which causes the contacts 30, 28 to open by the opening spring 52 associated with the toggle joint device 14.
  • the triggering of the mechanism 10 by the disengaging effect of the opening pawl 50 is ultra fast, and takes place before the intervention of the triggering member 70, which has a response time which is a function of the type of trigger. magnetothermic or electronic used in the circuit breaker.
  • the presence of the opening pawl 50 with self-disengagement of the latch 60 makes it possible to mechanically self-protect the circuit breaker in an ultra-fast manner, while remaining compatible with instantaneous protection of the trip device.
  • the ultra-rapid self-unlocking of the mechanism 10 is carried out for a high current level, in particular greater than 180 kA peak.
  • the opening pawl 50 according to the invention constitutes a modular sub-assembly, which is interchangeable with a conventional opening pawl, for example described in document EP-A-222,645.
  • the relative movement between the flanges 72 and the retaining lever 80 of the opening pawl 50 is effected by a rotational movement having a small angular clearance. It is clear that this relative displacement can be obtained by a translational movement thanks to an oblong light.
