Definitions

  • This invention relates to a hyper fast current limiting circuit breaker usable at medium voltage and more particularly suitable for electric traction with direct current in rolling stock or fixed equipment.
  • the device according to the invention eliminates the aforementioned drawbacks by avoiding the formation of a significant arc thanks to the complementary use of semiconductors and of a specific mechanism much faster still, called thereafter hyper fast mechanism.
  • US Patents 3723922 and US 3764944 describe a mechanism intended for a synchronous breaking device, for alternating network, in which the axial displacement of a disc connected to a movable contact bridge by a central shaft is obtained by repulsion using of spiral-shaped coils excited by a large current from the discharge of a capacitor specially designed for this use.
  • This device designed for high voltage in alternating current, works under a high vacuum. It uses complex manufacturing excitation coils and special devices for decelerating the central shaft. 29.26 / 1961.
  • the cut-off, without significant arc is obtained by the addition of an oscillating circuit, controlled by semiconductors and the inductor of which is used as a repulsion coil, to a super fast mechanism with electromagnetic holding in which the same element acts both as a repulsion disc and as a movable contact bridge.
  • the invention is characterized in that the separation of the contacts is obtained without significant delay as soon as the repulsion effort appears.
  • This repulsion effort quickly takes on considerable importance without requiring significant storage of energy in mechanical form (for example the deformation of springs or the pressurization of a fluid).
  • the opening delay is defined as the time that elapses between the start of the opening order and the moment when the movable contacts start to move away from the fixed contacts.
  • the opening speed must above all be important at the start of the race to quickly obtain a sufficient distance.
  • FIG. 1 shows the diagram used according to the invention
  • a switching device 1 is represented by an input terminal 2 located at A, an output terminal 3 located at B, a movable contact bridge 4,4 'and contacts fixed 5.5 ′.
  • This device is mounted in an external circuit 6 represented by the annotated elements L R and R R and supplied by a voltage source U represented at 7. Between the terminals 2 and 3 of the circuit breaker 1 are arranged the elements constituting an assistance circuit 8.
  • This assistance circuit is an oscillating circuit which comprises, a capacity 9, a choke 10, and semiconductors 11 and 12.
  • the discharge of the capacitor of the assistance circuit corresponds to the injection of a current warhead circulating in opposite direction of the current to be interrupted.
  • the fault current I def . reaches the value of the trigger threshold I sd .
  • the thyristor 11 is started by a detection system, not shown, placed in the main circuit 6.
  • a current warhead I i arises in the circuit formed by the capacitor 9, the choke 10 which, according to the invention, serves as a repulsion coil, the thyristor 11, the fixed contacts 5.5 ′ and the movable contact bridge 4.4 '.
  • This current warhead I i of several thousand amperes traverses the repulsion coil 10 of spiral shape and induced in a disc forming the movable contact bridge 4,4 ′ of currents such that this disc is violently repelled by the repulsion coil .
  • the choke 10 of the assistance circuit shown in FIG. 1 is fully or partially integrated into the device, and that the ignition of the thyristor 11 is controlled as soon as the fault circuit I def . reaches the value of the trigger threshold I sd .
  • the breaking device 1 is bidirectional, that is to say that it can be used by a current flowing from left to right as shown in FIG. 1 or for a current flowing in both directions according to the principle diagram explained later in FIG. 6.
  • a first imperative condition is to obtain a sufficiently short opening delay. In fact, it can be seen in FIG. 2 that the longer this opening delay, the greater the current to be cut.
  • a second imperative condition is to achieve a high opening speed.
  • the higher the opening speed the more quickly the inter-electrode space covers sufficient dielectric strength, capable of withstanding the rise in voltage between A and B when the capacitor 9 is recharged.
  • a third imperative condition is that the synchronization between the opening phase of the contacts and the sending of the antagonistic current takes place in a certain manner throughout the lifetime of the device.
  • Figure 3 shows the hyper fast mechanism of the circuit breaker according to our invention.
  • this mechanism consists of an insulating boot 20 of cylindrical shape, inside which slides a piston 21 guided in its center by a shaft 22.
  • the piston 21 is
  • the piston 21 is provided with an excitation winding called holding bohinage 25 concentric with a magnetic yoke 26 with which it collaborates.
  • the piston 21 normally in the high position under the action of the engagement spring 24 can be pushed down on the action of compressed air admitted into the top of the insulating housing 20 by an orifice 27.
  • the central shaft 22 carries at its lower end an armature 28 collaborating according to a work mode developed subsequently with
  • a recess made in the magnetic yoke 26 accommodates a spring called armature spring 29 for pushing the armature 28 when the magnetic attraction due to the retaining coil ceases 25.
  • Damping buffers 30 dampen the
  • a seal 32 seals between the piston 21 and the central shaft 22 which serves as a guide.
  • a third gasket 32 "seals between the piston 21 and the insulating housing 20 acting as a cylinder.
  • the central shaft 22 has in its upper part a reduction of diameter which serves as a shoulder for a disc called a repulsion disc 34.
  • This repulsion disc 34 is made of light alloy. In the embodiment this repulsion disc has a diameter equal to that of the insulating housing 20 and has on its upper side a bevel on which are arranged two contact elements identified at 35 and 36 and subse - surely called movable contacts 35 and 36.
  • the movable contacts 35 and 36 are diametrically opposite and are
  • the movable contacts 35 and 36 collaborate with contact pads identified at 37 and 38 and subsequently called fixed contacts 37 and 38.
  • These fixed contacts 37 and 38 are respectively integral with an input terminal 39 and an output terminal 40.
  • the super fast mechanism is also characterized by the fact that the repulsion disc 34 also acts as a contact bridge between the fixed contacts 37 and 38.
  • the two terminals 39 and 40 carry lugs 41 and 42 used to connect the cables of the main circuit.
  • terminals 39 and 40 are adjacent to the insulating box 20 by elements shown schematically.
  • an insulating mass 43 traversed in its center by the end of the central shaft 22.
  • the underside of the insulating mass 43 carries a cavity 44 in which is inserted a coil of spiral shape called coil repulsion 45.
  • This repulsion coil 45 is secured to the insulating mass 43 by an impregnating resin forming an insulating layer 46.
  • the insulating mass 43 is pierced with a central hole allowing the central shaft 22 to open outwards and is provided with a cavity in which is housed a spring called disc spring 47 serving to maintain the repulsion disc 34 in its low position.
  • a damper 48 dampens the end of travel of the repulsion disc 34 downwards.
  • the super fast mechanism shown in FIG. 3 as an exemplary embodiment according to the invention operates in the following manner. At the start, let us consider the open contacts, this position corresponds to the left part of FIG. 3 showing the movable contact 35 separated from the fixed contact 37.
  • the magnetic cylinder head 26 comes into contact with the armature 28.
  • the armature 28 is electromagnetically secured to the magnetic cylinder head 26.
  • the engaging spring 24 is allowed to push the piston 21 upwards at a controlled speed.
  • the armature 28 and the magnetic yoke 26 allows the central shaft 22 integral with the armature 28 to rise by driving the repulsion disc 34 upwards.
  • the movable contacts 35 and 36 are applied to the fixed contacts 37, 38 and the repulsion disc 34 acts as a contact bridge.
  • the super fast mechanism is then in the closed state.
  • the interlocking maneuver is a maneuver which takes place without using the phenomenon of electrodynamic repulsion.
  • the triggering maneuver is extraordinarily rapid following the very violent electrodynamic repulsion which makes it possible to reduce the opening time in a ratio of another order of magnitude.
  • the repulsion effort is sudden and violent, it corresponds to a real "Hammer blow which makes the electromagnetic lock established between the magnetic yoke 26 and the armature 28 jump.
  • the repulsion effort is of an order of magnitude much higher than that of the electromagnetic holding effort. It should be noted that in the exemplary embodiment of our invention presented in FIG. 3 and contrary to the other embodiments currently known, the electrodynamic repulsion essentially uses the current coming from the discharge of the capacitor of the assistance circuit.
  • the repulsion force corresponds to a significant acceleration at the start of travel of the repulsion disc 34 allowing it to quickly move the movable contacts 35 and 36 from the fixed contacts 37 and 38.
  • the removal of the repulsion disc 34 reduces the repulsion force which contributes not to further increase the speed of removal of the repulsion disc and to reduce the impact of the repulsion disc 34 on the damper 48 .
  • the damper 48 is simply represented by a layer of deformable material. It is obvious that this shock absorber can be of a more elaborate design. There may be other exemplary embodiments according to the invention.
  • a first variant of the embodiment shown in FIG. 3 consists in securing the repulsion disc 34 to the central shaft 22 and in making the fixed contacts 37 and 38 telescopic by the conventional combination of springs ensuring the mobility of the contacts 37 and 38 and braids ensuring conductivity from the contacts 37 and 38 to the ears 41 and 42. This arrangement allows an adaptation of the repulsion disc 34 carrying the movable contacts 35 and 36 on the contacts 37 and 38 in the event of asymmetrical wear of the various contacts.
  • a second variant consists in placing the hyper-rapid mechanism shown in FIG. 3 in a sealed enclosure containing a dielectric gas, so as to favor the eventual cut-off phenomenon by an inter-electrode space of higher dielectric strength.
  • the repulsion disc 34 is provided with oblique holes 49, 50 and a peripheral skirt 51.
  • the role of the peripheral skirt 51 is twofold. It consists on the one hand, of slowing down the repulsion disc 34 at the end of the race to avoid rebounds, and on the other hand, of avoiding the lateral escape of the fluid when the repulsion disc 34 descends so as to have, leave the oblique holes 49 and 50, from an energetic blowing directed on the possible arc.
  • Yet another variant consists in tilting the fixed contacts 37, 38 and the movable contacts 35, 36 inversely to that identified in FIGS. 3 and 4. According to this variant, the inclination of the contacts would be done so that the interfaces Communes are arranged according to straight lines, which extended by thought, would have their point of intersection towards the bottom of the apparatus.
  • FIG. 5 shows a second example of the mechanism, in which the piston 21 has been modified with respect to the first example exposed in FIG. 3.
  • This modified piston will be designated subsequently at 21 '.
  • the piston 21 ' roughly retains the same structure and strictly performs the same functions as the piston 21 described in FIG. 3. Only the holding coil 25 and the magnetic yoke 26 are replaced by a permanent magnet 53 fixed, by means known, at the base of a piston body 52 whose outer diameter, unchanged with respect to FIG. 3, allows the piston 21 'to slide inside the turns of the spring 24 and whose central bore, unchanged by compared to FIG. 3, allows the piston 21 ′ to slide along the turns of the reinforcing spring 29.
  • FIG. 6 represents the block diagram used when the breaking device 1 is called to cut the current whatever the direction of the latter.
  • the diagram of FIG. 6 differs from that of FIG. 1 by the presence of a counter-electromotive force 55 in the main circuit 6 by the addition to the thyristor 11 of a diode 54 mounted in antiparallel and by the replacement of the diode 12 by a thyristor 12 'in the assistance circuit.
  • the capacitor 9 is charged as indicated in FIG. 6, that is to say having the negative polarity at terminal 2.
  • the detection system As soon as the detection system detects the fault current I def . ' it controls the triggers of thyristors 11 and 12'.
  • the capacitor 9 discharges through a circuit constituted by the repulsion coil 10, the thyristor 11, the movable contacts 4,4 'and the fixed contacts 5,5' not yet open of the breaking device 1. Following the repulsion of the contact bridge 4,4 'under the action of the repulsion coil 10, the current warhead and the fault current pass through the thyristor 12'.
  • the current warhead While the fault current flows in the main circuit 6, the current warhead oscillates sinusoidally in the assistance circuit; the capacitor 9 charges in reverse polarity, that is to say by presenting a positive polarity at the terminal 2.
  • the thyristor 12 ′ is then subjected to two antagonistic currents, on the one hand the fault current, directed from the right on the left according to FIG. 6, which increases slowly, on the other hand the current warhead, directed from left to right, which increases suddenly until the cancellation of the current in the thyristor 12 '.
  • the thyristor 12 ′ blocks and the fault current then passes through the diode 54 to recharge the capacitor 9 with a polarity again reversed, that is to say negative at terminal 2.
  • the cutoff sequence is complete.
