Definitions
- the present invention relates to the field of protective devices for lines or electrical equipment and relates to a selective circuit breaker.
- a selective circuit breaker essentially consists of a main circuit, comprising a contact zone provided with at least one arc extinguishing chamber, a magnetic actuation device at the opening of the contact zone, and a first thermal bimetal, which acts on an unlocking lock, so that the contact zone is kept open, and by a secondary circuit, in parallel, and comprising a second thermal bimetal, which also acts on the unlocking lock, and a cutoff contact, which can be opened by said unlock lock.
- the secondary circuit is further provided with a current limiting resistor in said secondary circuit.
- Such selective circuit breakers are in particular known by DE-A-33 16,230 , DE-A-31 33 221 , DE-A-195 26 592 , DE-A-30 21 867 and WO-2008/131900 and allow, when a fault is detected, for example in the case of a short circuit, a temporary opening of the contact zone of the main circuit by action of the rod of the magnetic device and to switch on the secondary circuit. If the fault persists, the current, limited by the resistance and passing through the thermal bimetallic circuit of the secondary circuit, causes a heating of the bimetallic strip, having the effect of deflecting it in a release position of the unlocking lock and thus of total cutoff of the current. The reset of the circuit breaker must then be done manually, after the fault has been switched off.
- the magnetic device In the case where the fault is only of very short duration, the magnetic device returns to its rest position and the contact zone is restored without triggering the lock lock.
- a problem commonly encountered with selective circuit breakers lies in the fact that, when opening the contact zone of the main circuit, there is a vibration effect of the magnetic device, connected to the alternating current. Indeed, at the opening of the contact zone of the primary circuit, the force of the coil of the magnetic device disappears in the zero crossing of the alternation, so that the contact zone tends to recover and that the main circuit becomes a driver again. This results in a succession of trips, called the pumping effect of the coil, which has the consequence that the complete opening of the contact zone of the main circuit is difficult to perform, and that the operation of the main and secondary circuits is impaired, causing a rapid deterioration of the circuit breaker.
- circuit breakers make it possible to obtain acceptable results, both as regards the limitation of the pumping effect, by successive releases, and reliability.
- circuit breakers generally require at least two separate contact carriers and / or two separate locks, namely, respectively, for the main circuit and for the secondary circuit, so that their size is relatively large and their complex construction. It also results from such a construction an additional disadvantage related to the risk of implementation of a large number of moving parts, which can be detrimental to reliability.
- the present invention aims to overcome these disadvantages by providing a selective circuit breaker of simple and compact construction, in which the number of moving parts is reduced, and has a very high breaking capacity.
- the selective circuit breaker according to the invention which essentially consists of a main circuit, comprising a contact zone provided with a main contact bridge cooperating with two fixed contacts, each of which is provided with a contact chamber. arc extinguishing, a magnetic device in the form of an actuating coil at the opening of the main contact bridge, and a first thermal bimetallic overload protection, which acts on an unlocking lock, and by a secondary circuit, comprising a second thermal bimetal, which acts on the unlocking lock, a current limiting resistor in said secondary circuit, and a movable contact that can be opened by said unlocking lock, is characterized in that the lock unlocking device is a single lock cooperating with the main contact bridge and with the movable contact of the secondary circuit, said said main contact bridge and contact mobile act being mechanically connected to a common contact holder, with possibility of independent relative movement and being electrically independent of each other.
- FIGS. 2 to 6 appended drawings show a selective circuit breaker, which operates according to the electrical diagram of the figure 1 , and which essentially consists of a main circuit, extending between two connection terminals 1 and 2, and comprising a contact zone provided with a main contact bridge 5 cooperating with two fixed contacts 4 and 6, each of which is provided with an arc extinguishing chamber 4 ', 6', a magnetic device 3 in the form of an actuating coil at the opening of the main contact bridge 5 and a first thermal bimetallic strip 7 for protection against overloads, which acts on an unlocking lock 8, and by a secondary circuit comprising a second thermal bimetallic strip 9, which acts on the unlocking lock 8, a current limiting resistor 10 in said secondary circuit, and a movable contact 11 cooperating with a fixed contact 12 and can be open, namely remote from said fixed contact 12, by said unlocking lock 8.
- the unlocking lock 8 is a single lock cooperating with the main contact bridge 5 and with the movable contact 11 of the secondary circuit, said main contact bridges 5 and movable contact 11 being mechanically connected to a carrier. common contacts 13, with possibility of independent relative movement and being electrically independent of each other.
- the common contact holder 13 which is pivotally mounted on an axis 14, is manually operable, for reclosing or for a deliberate release, via a lever 15 provided with a rod 16 of actuation of the contact holder 13, said link 16 cooperating with a pawl 17 articulated on the contact carrier 13, which is loaded, in the operating position, by a spring 18.
- the contact holder 13 makes it possible to bring the main contact bridge 5 and the movable contact 11 of the secondary circuit into contact with the respective fixed contacts 4, 6 and 12, the contact force of the movable contact 11 against the fixed contact 12 of the secondary circuit being provided by the bracing force of the rod 16 of the lever 15, while the double contact between the main contact bridge 5 and the fixed contacts 4 and 6 is provided by specific springs which will be described in relation to said main contact bridge 5.
- the arc extinction chambers 4 ', 6' are advantageously arranged parallel to each other.
- the main circuit which extends between the connection terminals 1 and 2 and comprises the main contact bridge 5 cooperating with the two fixed contacts 4 and 6, the magnetic device 3, and the first thermal bimetal 7 of overload protection, is advantageously integrated in the lower part of a modular housing (not shown), the coil of the magnetic device 3 being mounted between a connection terminal 1 and a fixed contact 4 of the contact zone, of which the another fixed contact 6 is connected to the first thermal bimetallic strip 7, which is connected to the other connection terminal 2.
- the secondary circuit which comprises the second thermal bimetallic strip 9, the current limiting resistor 10 and the movable contact 11, is connected to the main circuit, parallel to the contact zone provided with the main contact bridge 5 and the first thermal bimetallic strip 7 of protection against overloads, between the coil of the magnetic device 3 and the connection terminal 2 of said main circuit.
- the secondary bimetallic strip 9 of the secondary circuit is disposed in the upper part of the modular housing, above the main circuit and close to the lever 15.
- the main contact bridge 5 is made in the form of a U-shaped piece whose wings 5 'bear their free end on the fixed contacts 4 and 6 of the main circuit and whose core 5 " forms a pivotal mounting pin on the contact holder 13.
- the contact carrier 13 advantageously has an open bearing 20 for receiving and pivoting the core 5 "of the main contact bridge 5, the side of the opening opposite the fixed contacts 4 and 6, seen in the direction of pivoting at the opening of the bridge 5, simultaneously forms a stop 21 for limiting the deflection at the opening of said bridge 5, by cooperation with a wall 5 "', or other connecting element extending between the core 5" and the wings 5' of the U forming the bridge 5.
- the main contact bridge 5 is held on the contact carrier 13 by means of springs 22 acting by one of their ends on a pin 23 or the like, provided externally along each wing 5 ', and whose other end cooperates with an attachment pin 24 provided on the contact holder 13.
- the mounting of the main contact bridge 5 on the contact carrier 13 with the springs 22 is such that the positioning of the main contact bridge 5 on the contact carrier 13 is always unstable, i.e. the main contact bridge 5 always tends to return to the service position against the fixed contacts 4 and 6 of the main circuit.
- the mounting of the springs 22, in particular their attachment on the pins 24 of the contact holder 13 is made such that in the open position ( figure 8 ) of the main contact bridge 5 by the magnetic device 3, its wall 5 "'bearing against the stop 21 of the contact holder 13, the longitudinal axis of the springs 22 does not exceed the unstable equilibrium point, c' that is to say, is set back with respect to the axis of the core 5 "of the main contact bridge 5.
- the springs 22 press force the two wings of said bridge 5 against fixed contacts 4 and 6, while in the open position ( figure 8 ) the bridge 5 is in abutment against the lower part of the open bearing 20 of the contact holder 13, the springs 22 always having a tendency to bring the bridge 5 against the fixed contacts 4 and 6 of the main circuit.
- the main contact bridge 5 in the triggering or manual opening position of the lock 8 ( figure 9 ), the main contact bridge 5 is in abutment against a stop 25 of the contact holder 13, provided at the end of the open bearing 20, on the opposite side to the stop 21.
- the attachment points of the springs 22, namely on the lug 23 of each wing 5 of said main contact bridge 5 and on the hooking axis 24 of the contact carrier 13, are advantageously arranged in a plane parallel to the plane passing through the open bearing 20 at a distance d, in the closed position of the contacts, such as in the open position of said contacts, the parallel planes are at a distance of close to zero, that is to say the point of unstable equilibrium, so that the resistance force to the opening of the bridge of main contact 5 decreases or remains substantially constant during the opening path.
- the operation of the main contact bridge 5 and thus its opening speed are improved and the holding in the open position in selector position of the circuit breaker is facilitated.
- each spring 22 is positioned so that its length at rest, that is to say not loaded, is less than that which it has when the main contact bridge 5 is pressed against the contacts. fixed 4 and 6.
- the opening movement of the main contact bridge 5 is accompanied by an increase of the length of the springs 22.
- the restoring force increases during the opening movement. Nevertheless, the return torque exerted by the springs 22 on the main contact bridge 5 may decrease during the travel of said main contact bridge 5.
- the return torque is obtained by the return force which applies to a location offset from the axis of rotation of the main contact bridge, so as to determine a lever arm d, measured perpendicularly to the axis of the force created by the springs 22, between the axis of this force and the point rotation of the main contact bridge 5, this lever arm decreasing to reach a very low length in the maximum open position of the main contact bridge 5.
- the configuration of the anchoring points of the springs 22 and the axis of rotation 5 "of the main contact bridge 5 is such that this lever arm decreases during the opening path of the main contact bridge 5. This is achieved by ensuring that, throughout the opening path of the main contact bridge 5, the triangle formed by the pivot point of the main contact bridge 5 and the two ends of each spring is such that the angle of each corresponding vertex at the ends of the spring decreases and is always less than a right angle.Thus, it is possible, thanks to the reduction of the lever arm and by a choice of the technical characteristics of the springs 22, to obtain a substantially constant return torque, or even decreasing during the opening movement of the main contact bridge 5.
- said current limiting resistor 10 in the secondary circuit is advantageously wound around the coil of the magnetic device 3.
- Such an embodiment makes it possible to fill the fall of the magnetic force during the insertion of the secondary circuit, by adding additional ampere turns, thus avoiding a phenomenon of pumping or successive triggers of the coil.
- the movable contact bridge 5 must be kept open during the transition to 0 of the alternation, to avoid the creation of new arcs at the reappearance of the current and therefore to allow to the secondary circuit to continue to be powered.
- the coil of the magnetic protection device may also be provided, either on its fixed core, or on its movable core, or on the yoke, with a ring of phase shift.
- a phase shift ring has the effect of creating a phase shift of a portion of the flux and prevents the magnetic force from becoming zero.
- the force exerted by the magnetic device 3 on the main contact bridge 5 depends on the gap between the fixed and mobile cores of the magnetic device 3. This force increases as the air gap decreases. Thus, at the start of the movement, this force is the weakest, while it is the highest when the two nuclei are in contact, at the end of the opening movement.
- the magnetic force creates a torque on the main contact bridge 5, via a constant lever arm, this torque acting in the direction of the opening of the main contact bridge 5 relative to the fixed contacts 4 and 6.
- the winding of the current limiting resistor 10 in the secondary circuit around the coil of the magnetic device 3 thus makes it possible to provide additional magnetic force for the opening of the main contact bridge 5.
- the main contact bridge 5 By the embodiment described above of the main contact bridge 5, on the one hand, and the magnetic device 3, on the other hand, it is possible to obtain, on the one hand, an excellent retention of the main contact bridge 5 in the closed position, as well as, on the other hand, an opening facilitated during magnetic actuation on opening. Indeed, because of the very short distance d, the actuation of the main contact bridge 5 by the moving element of the coil of the magnetic device 3 can be performed under a force F substantially constant, namely a force of increasing only slightly, or even decreasing, so that the force produced by the moving equipment during the actuation will promote a quick opening.
- the additional prediction of the wound resistance on the coil of the magnetic circuit possibly combined with a phase shift ring, also contributes to an improvement in performance, namely to maintain the bridge 5 in the open position ( figure 8 ).
- the contact carrier 13 is provided with a pawl 17 pivotally mounted on said contact carrier 13 and comprising a first lever 17 'intended to cooperate with the first thermal bimetallic strip 7, and a second lever 17 "intended to to cooperate with the second bimetallic strip 9.
- the first thermal bimetallic strip 7 of the main circuit and the second bimetallic strip 9 of the secondary circuit are respectively connected to the corresponding connection terminal 2 and to the movable contact 11 via a braid 7 ' , respectively 9 ', the first thermal bimetallic strip 7 being further provided with an adjustment screw 19.
- the connection between the bimetallic strip 9 of the secondary circuit and the movable contact 11 can be carried out in such a way that extremely simple, without moving parts, such as a contact holder.
- the mounting of the first thermal bimetallic strip 7 of the main circuit is also considerably simplified.
- the use of braids provides optimum operational safety.
- the circuit breaker In the operating position represented at figure 2 , the circuit breaker is in the engaged position, its lever 15 being positioned opposite the mark ON. In this position, the circuit breaker is powered by one of the terminals 1 or 2, and the current flows mainly in the main circuit, the current flowing in the secondary circuit being negligible. Thus, the current passes through the coil of the magnetic protection device 3, the main contact bridge 5 and the first thermal bimetallic strip 7 of overload protection connected by its braid 7 'to the connection terminal 2.
- the coil of the magnetic device 3 which is traversed by the current, generates a magnetic field which will have the effect of moving the moving element of said coil, namely a plunger and a striker, towards the main contact bridge 5, to push the latter in an open position, as represented at figure 3 attached drawings. It follows that the two parts of the main contact bridge 5, which cooperate with the two fixed contacts 4 and 6 of the main circuit and the respective arc extinguishing chambers 4 ', 6', are separated.
- FIG. figure 5 The accompanying drawings show the operation of the circuit breaker according to the invention in the event of thermal tripping. overloaded.
- the circuit breaker being in the service position shown in FIG. figure 2
- the thermal bimetallic strip 7 overload protection of the main circuit heats up and deflects after a predetermined time by setting the The bimetallic strip then bears on the lever 17 'of the pawl 17, which pivots about its pivot axis on the contact holder 13, and releases the link 16 connected to the lever 15, so that that the contact holder 13 is no longer maintained in its bearing position against the return spring 18, which causes the rotation of said contact carrier and the separation, on the one hand, of the main contact bridge 5 of with the fixed contacts 4 and 6, and on the other hand, the movable contact 11 of the secondary circuit of the fixed contact with which it cooperates, so that all the contacts are found in the final trigger position of the circuit breaker represented at figure 6 attached drawings.
- the invention it is possible to achieve a selective circuit breaker having a very small footprint, because of a refocusing of all the mechanical elements around a single lock, the movable contacts of the primary circuit and the secondary circuit being mounted independently, both mechanically and electrically, on a common contact carrier.
