Definitions

  • the invention relates to an ultra-fast electrical switchgear having limiter circuit breaker function.
  • circuit breakers whose opening is obtained by a spring mechanism, and having a very short response time when triggered on default. It has notably been proposed, in document EP 780 380, A1, to use the reaction mechanics resulting from the electrodynamic compensation of the compensated contact members to trigger an automatic trigger.
  • the opening pawl has disengageable actuating means causing the lock to self-unlock in presence of a short-circuit current exceeding a calibration threshold defined by a spring, said self-unlocking being controlled on the basis of a mechanical reaction generated by the effect of electrodynamic compensation, and causing an ultra-rapid rotation of the lock to unlock the opening pawl before the intervention of the triggering device.
  • the invention therefore aims to remedy the drawbacks of the state of the art, so as to offer an extremely reliable, extremely fast opening circuit breaker, relatively compact, and of reduced cost which allows a separation of the contacts and an effect limit without waiting for the current intensity to exceed a limit threshold.
  • a drive mechanism independent of the actuator allows everything first of all to limit the number of operations that the fast actuator must carry out since some of the openings can be made by actuating the lock on the mechanism.
  • the actuator only has to supply the energy required to move the second contact to the separation position.
  • the mechanism drives the contact holder towards the open position which has the effect of further moving the movable contact from the first contact. In other words, part of the stroke of the movable contact with respect fixed contact is ensured by the opening spring of the mechanism. Sizing the actuator and associated electronics is greatly simplified.
  • the redundancy of the opening functions also allows operation degraded when the power supply or power electronics associated with the ultra-fast actuator, or even the actuator itself, has failed.
  • the circuit breaker behaves like a conventional limiting circuit breaker.
  • the overall reliability of the cut-off function of the device is improved.
  • the apparatus further comprises a pressure spring of contact recalling the second contact to the contact position, when the second contact is close to the contact position.
  • the contact pressure spring takes support on the mobile cage.
  • the pressure spring of contact is supported on a device support, the second contact being linked to the cage by a kinematic link.
  • the drive mechanism includes means for closure to bring the drive mechanism from the open position to the closed position, the drive train driving the cage of the open position to closed position when the drive mechanism passes from the open position to closed position.
  • the closure means include a closing spring which discharges to bring the mechanism from the open position in the closed position.
  • the storage spring is then called the opening spring, to distinguish it from the closing spring.
  • the apparatus may be of the type in which the energy necessary to load the opening spring is first stored in the spring closing, the discharge of the closing spring allowing the arming of the spring opening.
  • it can be of the type where the energy required to arm the closing spring is first stored in the opening spring, the discharge of the opening spring for arming the closing spring.
  • the same spring can ensure closing and opening on fault.
  • the apparatus further comprises a means of retention of the second contact in a retention position located between the position of contact and the separation position, as long as the cage is in the closed position.
  • These means retention ensure retention in the retention position, pending opening of the mechanism by the accumulation spring.
  • the means of retention includes a movable non-return lock between a neutral position and a non-return position and passing from the neutral position to the non-return position when the second contact goes from the contact position to the separation position, the non-return lock in position non-return locking the second contact in a locked position close to the separation position as long as the cage is in the closed position.
  • an articulation mechanism can be provided bistable between the second contact and the cage, by means of the contact pressure springs, so that when the second contact is near the position of separation, it is returned by the contact pressure spring to the separation position.
  • a device has the disadvantage of being less reliable in the event of a rebound.
  • second contact in the separation position It is therefore useful to plan a upper end stop for the second contact, which is able to absorb kinetic energy of the second contact.
  • the room and the means of electromagnetic drive of the arc are dimensioned so that the arc goes out even before the drive mechanism was able to move the cage.
  • we obtain the projection of the arc towards the room in particular by giving a shape suitable for the conductors connecting the contacts to the connection pads, for example a current loop form. You can also introduce a U-shaped magnetic circuit surrounding the contact area, to produce a strong electromagnetic field in the area where arises the electric arc during the separation of the contacts.
  • the apparatus further comprises a supply device electric to power the electromechanical actuator and deliver electrical energy necessary to move the moving part from the rest position to the active position.
  • the power supply device includes an energy storage means electric. In practice, it is one or more power capacitors which allow the accumulation of electrical energy and its almost instantaneous restitution for actuator supply.
  • the supply device electric is connected to an electric source independent of the electric power circuit. However, it is also possible to envisage an order whose source the electrical power circuit in which the contacts of the apparatus.
  • This solution allows in all cases to control the opening of the relay by through the triggering device but to impose conditions of specific triggering of the relay in the event that the opening of the mechanism is preceded separation of the contacts by the electromechanical actuator.
  • the measurement means are constituted by Rogowsky tori.
  • the electromechanical actuator is constituted by a thruster with Thomson effect.
  • any other ultra-fast electromechanical propellant is possible.
  • a housing 10 of insulating material of a circuit breaker low voltage power limiter contains in its front part a mechanism 12 to drive a pivoting switch bar 14 which transmits to the device's poles 16, located in the rear part, the movements of the mechanism 12.
  • the drive mechanism 12 is carried by a chassis not shown, fixed by relative to the housing 10, and comprises a toggle device having a pair of rods transmission 20, 22, articulated to each other by a pivot axis 24.
  • the connecting rod upper 22 is mechanically coupled to the switching rod 14 by an axis 25.
  • the lower link 20 is articulated via a pin 26 to a hook 27 pivoting around a fixed axis of rotation 28.
  • An opening lock 30 locks the hook 28 in an armed position by means of a reduction lever 32.
  • the lock opening 30 is actuated using an electromagnetic relay 34.
  • An opening spring 36 is stretched between the axis 25 and a cleat fixed to the chassis.
  • the mechanism is completed by an arming and closing sub-assembly comprising a transmission lever 40 provided with a pin 42 cooperating with the device toggle joint, a roller along the curve of an arming cam 44 and an anchoring pin 46 of the end of a closing spring 48.
  • the accumulation sub-assembly is completed by a closing lock 50 blocking the transmission lever 40 via a reduction hook 52.
  • the rotation of the arming cam 44 until its locked position allows the transmission lever 40 to be pivoted by one disarmed position to an armed position and load the closing spring 48, without interfere with the opening mechanism.
  • the transmission lever 40 is locked by the closing latch 50. Unlocking the lever 40 allows the closing spring 48 to drive the lever 40 from the armed position to the disarmed position, the transmission axis 42 then driving the toggle joint device in the closed position and charging the opening spring.
  • the switching bar 14 is common to all of the poles 16 which can be for example three, four or six, although other configurations are possible, and is constituted by a shaft supported by bearings of the housing to pivot around a fixed geometric axis between an open position and a position of closing.
  • a connecting rod 54 which connects a crank 56 of the bar to a movable cage 58 of insulating material.
  • the cage 58 pivots around a geometric axis 60 fixed relative to the chassis.
  • One or more fingers of movable contacts 62 are pivotally mounted around the same axis 60, and connected by a braid 64 to a connection pad 66.
  • the movable contact fingers 62 carry pads contact 68 which, in the position of FIG.
  • connection pad 72 connecting rods telescopic 74 are used to guide contact pressure springs 76 arranged between the cage 58 and the fingers 62.
  • the contact pressure springs 76 are, in the example considered, compression springs, which tend to rotate the contact fingers 62 relative to the cage 58 anticlockwise in the figures, so as to recall the contacts 68 of the fingers 62 towards the fixed contact 70.
  • the cage 58 carries an elastomeric end stop 78 limiting the pivoting movement of the fingers contact 62.
  • a retractable lateral lock 80 is articulated around an axis 82 passing through fingers and supported by them.
  • a stop 84 is arranged on the bottom of the housing, in look of the lock 80.
  • a leaf spring 86 is fixed to one end of the lock 80, opposite a nose 88 protruding from the cage.
  • An arc extinguishing chamber 90 opens facing the contacts, its mouth being delimited by a spark arrester 92 and a bow horn 94 connected electrically at the connection pad and at the fixed contact 70.
  • the chamber contains metallic cooling fins 96 and opens to the outside via a bottom grid 98 opposite the contacts 68, 70.
  • a Thomson 100 effect thruster is placed in the base of the box, opposite contact fingers 62.
  • this thruster consists of a disc 102 disposed opposite a winding 104 and secured to a percussion head 106.
  • a rod 108 is fixed to the head 106 and guided in a fixed cylinder 110.
  • a spring of recall 112 tends to bring the head 106 towards the winding.
  • the head 106 constitutes a hammer 114 intended to strike the contact fingers 62.
  • a Rogowsky 120 torus surrounds connection pad 66 and is used for measurement of the current passing through the pole 16.
  • the toroids 120 of the three poles deliver a signal to a control unit 121 comprising a first module 122 electronic trigger and a second electronic trigger module 124.
  • the first electronic module 122 very conventionally controls the relay electromechanical 34 driving the opening lock 30.
  • the second electronic module 124 controls both the electromechanical relay 34 and a power electronics module 130 used to supply the Thomson 100 thruster.
  • line 125 connecting the second electronic module 124 to relay 34 is optional, and can be the case if necessary be omitted, hence its representation in broken lines.
  • the second module electronic controls the electromagnetic relay 34 in the event of ultra-rapid opening, through the module 122.
  • the second module is capable of determining whether the signal delivered by the toroids 120 is characteristic of a fault requiring an ultra-rapid opening of the circuit breaker.
  • the means for making this decision are well known to those skilled in the art, and described by example in document DE 36 42 136, as well as in the French patent application bearing the registration number 01 15 785.
  • the power electronics module is provided with a capacitor bank of power used to store the electrical energy necessary to activate the propellant 100.
  • the module 130 is supplied with power by a clean supply 134.
  • torus 120 delivers a signal such that only the first module electronics 122 sends a signal to the electromechanical relay 34 which unlocks the lock opening 30.
  • the opening spring 36 then drives the switching rod 14 towards the open position shown in FIG. 2. This movement is transmitted to the cages 58 of the different poles 16 by the connecting rods 54.
  • the contact fingers 62 biased by the springs of contact pressure 76, follow the opening movement.
  • the contact fingers 62 have pivoted clockwise, causing an electric arc upon separation of contacts 68, 70 and thus a limitation of the current, this even before the mechanism 12 has driven the cages 58 to the open position. Due to this pivoting of the fingers 62 before setting the cage 58 in motion, the leaf spring 86 meets the nose 88 of the cage and rotates the latch 80 relative to the fingers 62 so that the latch 80 comes come between the fingers 62 and the stop 84.
  • the fingers 62 start a movement in the counterclockwise but are immediately locked in the position shown in Figure 3, because the latch 80 came into contact with the stop 84 and prohibits the drop of contact fingers 62.
  • the lock is deactivated by opening the device which causes the cage 58 to pivot, so that the nose 88 moves away from the leaf spring 86.
  • the return to the retracted position of the lock 80 is effected by simple gravity or using a torsion spring not shown in the figures, recalling the latch 80 anticlockwise. So for slow or low amplitude faults, the circuit breaker behaves like a circuit breaker Conventional snap-on limiter.
  • the second electronic trigger module 124 whose response time is much longer shorter than that of the first trigger module 122, takes priority. He commands on the one hand the power electronics 130 and on the other hand, simultaneously or timed, as required, electromagnetic relay 34. Power electronics 130 then instantly releases electrical energy into the Thomson 100 thruster stored in capacitors 132. In less than a millisecond, the hammer 114 of the thruster head strikes the contact fingers 62 and projects the pivoting fingers into clockwise around the axis 60, the cage 58 remaining stationary.
  • the fingers 62 come in abutment against the abutment 78 of the cage while the latch 80 pivots and is in place.
  • the lock 80 comes to block them as shown in Figure 3.
  • an electric arc is drawn between the contact.
  • the shape of the copperware forming the electrical circuit between the ranges of connection 66, 72 has a loop effect on the arc which projects the arc towards the chamber.
  • the bow switches on the spark arrester 92 and on the arc horn 94, which facilitates its entry into the extinguishing chamber 90 while providing the contacts 68, 70.
  • the arc cools, so that its electrical voltage increases to extinction.
  • Mechanism 12 confirms the opening in driving the cage 58 in the open position of Figure 2.
  • the sequence opening has the same steps as in the case of an electrodynamic repulsion, but its progress is much faster. There are indeed less than three milliseconds between zero current and activation of the Thomson effect thruster, so that the intensity of the arc current is very low and the arc is easy to cut. If we had to rely on the electromagnetic repulsion effect between the contacts, wait until the current intensity has exceeded an already high limitation threshold, and the separation of the contacts would give birth to a very energetic arc from the start.
  • the toroids of Rogowsky deliver their signal to an electronic control unit 121 which comprises a module 152 for detecting faults and discriminating between faults requiring a activation of actuator 100 and fault requiring only the opening of the mechanism.
  • the detection module 152 informs a control module 154 which sends signals to the relay 34 and / or to the power electronics module 130 adequate control.
  • circuit breaker presented is not limiting and the invention would also be applicable to single-pole devices.
  • Contact pressure springs can be arranged between contact fingers mobile and an element integral with the housing, as described for example in the document US 4841266. It can also be provided to perform the anti-return function of the wedge using contact pressure springs forming a bistable system between the cage and the fingers contact, as described for example in the same document US 4,841,266. Thus, when the contact fingers are close to the contact position, the springs of booster ensure contact pressure while when fingers are in position separation, the springs tend to keep them there.
  • the contact pressure springs 76 can be calibrated so that the contact fingers 62 never rise by electromagnetic repulsion effect, before one of the tripping devices causes the separation of the contacts, by opening of the mechanism 12 or by activation of the thruster 100. This then gives a device with high electrodynamic resistance, ensuring very strong current limitation extremely high via thruster 100.
  • Two retractable lateral stops can be provided framing the cage if the width of the cage, in a direction perpendicular to the plane of the figures, makes it necessary. Other forms of stops are possible.
  • the retractable stop can be fixed to the bottom of the case. It can also come between the cage and the fingers.
  • the Thomson effect propellant or other actuator ultrafast can be placed on the cage to rotate the fingers.
  • the opening lock can also be controlled by undervoltage detection means, which will act either on electromechanical relays separate from relay 36, or on relay 36 itself.
  • the mechanism described in the exemplary embodiment is a mechanism of the type allowing an opening, closing, opening cycle, with an opening spring and a separate closing spring.
  • the invention is applicable to any other type of conventional circuit breaker mechanism, in which the energy required to open is stored in an accumulation spring. It is particularly applicable to circuit breaker, the mechanism of which comprises a single spring ensuring both opening onto fault and closing of the apparatus.
