Definitions

  • the present invention relates to electrical devices with automatic cut-off, in particular differential switches, circuit breakers or differential circuit breakers, or else devices combining several of these functions, of the type of those comprising between a rotary actuator, actuated for example by using an operating lever or by push button, and a tilting contact carrier on which is mounted at least one movable contact each cooperating respectively with a corresponding fixed contact and which is biased by a first spring in the direction of opening or separation of the movable contact from the fixed contact, a toggle and ratchet mechanism capable, on the one hand, when this mechanism is tensioned, of transmitting the movement of the operating member to the contact carrier both in the opening direction only in the contact closing direction and, on the other hand, when this mechanism is relaxed by triggering means a sliding independently of the operating member on the pawl, causing the contact carrier to return from its closed position to its open position, this mechanism being arranged so as to allow the operating member to reset the device, that is to say to tighten the mechanism by bringing it back from its opened open position to
  • the object of the invention is to improve a mechanism of the type of that of patent application EP-A-0.143.682 in order to allow it to be actuated by several different triggering means which act independently of the operating member on the pawl and in particular tripping means such as thermal trip bimetal, electromagnetic trip plunger and, of course, auxiliary tripping relay such as voltage relay or differential switch relay.
  • triggering means such as thermal trip bimetal, electromagnetic trip plunger and, of course, auxiliary tripping relay such as voltage relay or differential switch relay.
  • Another objective of the invention is to achieve such an improvement so as to allow an optimal spatial distribution of the triggering means in the volume offered by the device carrying the mechanism.
  • Yet another objective of the invention is to improve the mechanism so as to ensure maximum longevity and efficiency and a lower cost price both with regard to the individual parts and the assembly, and this, in particular, by eliminating the holders important overhangs.
  • the invention relates to such an electrical device with automatic cut-off, in particular differential switch, circuit breaker or differential circuit breaker as defined in claim 1.
  • the pawl has three zones or reliefs of this kind so that it can be tilted for tripping both by a differential switch relay and by a tripping bimetal and by an electromagnetic tripping element, for example a plunger core an electromagnetic circuit breaker coil.
  • the pawl is shaped like a lever extending in a direction clearly transverse to the direction of the articulated rod and the lever trigger, having its axis of articulation at one end of the pawl.
  • the pawl cooperates, by one of said reliefs, with a triggering part or lever also ensuring the resetting of a differential switch relay, this lever being returned to the resetting position by a spring and this, preferably by by means of a pivoting part returned by a spring, preferably independent, and by the contact carrier, in the ratchet release position and kept away from this position, and against the action of its spring, by the reset lever acting as a pawl for retaining the pivoting part.
  • the pivoting part has a resetting means, preferably in the form of a lever arm, the end of which can be actuated by the mechanism when it returns to the open position in order to tilt said part in reset position in latching position with the relay release and reset part.
  • the mechanism can be mounted on an internal structure of an apparatus, so as to be arranged in an area extending parallel to an area containing tripping means such as bimetallic strip and / or electromagnetic circuit breaker, the pawl having fingers located in the travel of these triggering means, while the triggering lever, and the relay reset, with its pivoting intermediate piece, is housed in the zone of the mechanism under a zone receiving the relay.
  • tripping means such as bimetallic strip and / or electromagnetic circuit breaker
  • the toggle mechanism can be designed in such a way that the breaking of the toggle, when triggered, takes place in a direction away from the plane which joins the axis tilting of the contact piece and the pivot axis of the rotary actuating member.
  • the electrical appliance shown comprises a modular housing produced in the form of two half-housings 1, 2, connected at the level of a separation line 3.
  • the lower half-housing 2 usually exhibits hooking means 4 , 5 on a rail while the upper half-casing 1 has two pairs of successive shoulders 6, 7 and an apex 8 provided with a passage 9 for the manual actuation lever of the mechanism.
  • the extreme edges of the housing each have, in the lower half-housing 2, each time two openings 10 allowing access each time to the two cage terminals of the apparatus and the shoulders 6 each have two passages 11 for access to the screws of the respective cage terminals.
  • the device Inside the housing formed by the two half-housings 1, 2, the device is mounted on a structural part 12 having a generally symmetrical shape with respect to a vertical median plane forming a median partition 13 provided with a certain number of passages.
  • This structural part receives, at its ends, the cage terminals 14 with their screws 15. It also supports thick copper blades 16 suitably bent and having the fixed contacts and it has, for the axes of rotation of the mechanism parts, bearings supplemented by an auxiliary part 17 completing the structural part and the details of which will not be described here either.
  • the structural part defines, in the housing, a certain number of zones, namely, in addition to the zones receiving the terminals, two contact zones 18, disposed on either side of the central partition 13 at the bottom of the structural part 12, a measurement zone 19 capable of receiving a set of differential detection toroids, a magnetothermal tripping zone 20 located on one side of the central partition 13 above one of the zones 18, a trigger zone 21 intended to receive a differential switch relay and extending, towards the upper part of the device, over any the width of the structural part, a zone 22 of the trigger lock mechanism which is roughly symmetrical with the magnetothermal trigger zone 20 on the other side of the central partition 13.
  • the contact areas 18 receive, in addition to the fixed contacts carried by the blades 16 and the usual arc or arc chambers 23, the respective mobile contacts carried by a single rotary contact holder.
  • the toroidal area 19 receives the detection toroid assembly 24.
  • the magnetothermal circuit breaker 20 receives a circuit breaker, the details of which will not be described but which, on the one hand, has a circuit breaker 25 sensitive to the intensity which traverses it to struggle in the part of the zone 20 which is reserved for it, and a set of magnetic disjunction comprising a coil 26 capable, when it is traversed by an overcurrent, of causing, against its return spring 26a, a plunger core 27 comprising an integral striker 28, the plunger core having at its rear end a part 29 recalled by the return spring 26a of the plunger core and capable of acting on the mechanism.
  • the relay 30 is arranged with its rod 30a capable of moving vertically downwards when the relay is energized, that is to say in a direction perpendicular to the direction, horizontal on the drawing, of displacement of the plunger 27 with its striker 28.
  • the mechanism is of the toggle and ratchet type and extends between a manual rotary operating member 31 with its operating lever 32 mounted on an axis 33 fixed in the structural part, and a contact carrier 34 rocking around its axis 35, also carried by the structural part and usually carrying the movable contacts 36, cooperating with the fixed contacts 37 formed in the blades 16, the movable contact holder 34 being capable of tilting between a contact opening position, shown in particular in Figures 1, 2, 10 and 14, and a contact closed position shown in particular in Figures 11 and 15.
  • the movable contacts 36 and, therefore, the contact carrier 34 are biased in the opening direction contact by two powerful springs 38 which extend, in compression, between a bottom 39 of the auxiliary part 17 and a boss 40 of the respective movable contact.
  • the assembly of the contact carrier and of the movable contacts is preferably arranged in the manner described in the French patent application FR-A-83.15783 of October 4, 1983, that is to say so that the same springs ensure that both the separation of the contacts 36, 37 during the opening movement and the pressure of the contacts 36, 37 on each other in the closed position.
  • the mechanism is capable, on the one hand, when it is tensioned, of transmitting the movement of the operating member 31 actuated by the lever 32 to the contact carrier 34, both in the opening direction and in the direction of contact closure and, on the other hand, when the mechanism is relaxed by triggering means acting independently of the lever on a mechanism pawl, to cause the return of the tilting contact carrier 34 from its position closed in its open position, even if the lever is held.
  • the mechanism is further arranged so as to allow the lever 32, as soon as it is released, to reset the device, that is to say to re-tighten the mechanism by bringing it back from its position after tripping ( Figures 13 and 17) in its normal opening position (FIGS. 1, 10 or 14), after the intervention of the triggering means has ceased, and this under the action of a spring 41 acting on the rotary actuating member 31 in the direction of the contact opening, that is to say counterclockwise in FIGS. 11 to 13.
  • the connecting rod 42 is preferably articulated at its upper end in a housing taken in the thickness of the rotary operating member 31 and the connecting rod 44 can advantageously be made in the form of a link consisting of two identical parallel arms having the passages for the axes 45, 46, these arms being interconnected by an integral cross-member 59.
  • the useful length of the connecting rod 42 is significantly greater than that of the connecting rod 44.
  • the length of the groove 49 formed in the trigger lever 47 is sufficient to allow all the movements of the axis 45 in the different operating positions of the mechanism.
  • the contact carrier 34 has a transverse arm 60 which extends through the rectilinear trajectory of the striker 28 when the plunger core which carries the latter is violently displaced by the appearance of an overcurrent in the coil 26 so as to cause abrupt rotation of the contact carrier and, consequently, the lifting of the movable contacts 36 by the forced separation from the fixed contacts 37 after opening the toggle.
  • the relay reset and trigger lever 68 is intended, in the event of a trigger under the action of the relay, to be driven and tilted by the movable rod 30a of the relay thus releasing the trigger part 61 and, at the end tripping and once the relay is no longer energized, to return this rod 30a to the reset initial position.
  • the connecting rod 42 and the connecting rod 44 are held at the obtuse angle shown in the figures by a stop suitably disposed on the intermediate part 17, cooperating with an end projecting from the axis 43 between the lever and the connecting rod, and which prevents that continues the clockwise rotation of the operating member 31.
  • the contact carrier 34 is, in turn, essentially pushed clockwise by the powerful springs 38 and remains held in the open position shown against a stop of the fixed structure of so that the springs 38 are then without influence on the rest of the mechanism and in particular the rod and the rod.
  • the movable contacts 36 are therefore distant from the fixed contacts 37.
  • the trigger lever 47 articulated at its fixed point 48, remains held in its position by the abutment effect of the protruding part of the axis 45 between rod and rod in the groove 49 of the trigger lever and, in this position, we see that there is a slight clearance between the two nozzles 57 and 58 of the pawl 50 and the trigger lever 47.
  • the pawl 50 for its part, remains held in the position shown under the action of its return spring 50a which tends to rotate it clockwise, while being held in this position by the stop effect of the free end of the rib 47a of the trigger lever 47.
  • the trigger piece 61 urged clockwise by its spring 64, remains held in the position shown by the fact that the end of its long arm abuts against an end protruding from the axis 46 between the link rod and the contact carrier, while the lever rea mement of relay 68, abuts on the relay rod 30a, the rod 30a being in the high position inside the relay 30. There is then a clearance between the two nozzles 67 and 72 of the reset lever 68 and the part pivoting trigger 61.
  • the contact carrier has tipped against its springs 38 and, in this movement, the movable contacts 36 come to meet the fixed contacts 37, after which the further tilting of the operating lever 31 causes the final phase of the tilting of the contact carrier 34 so that, in a manner known per se, the springs 38 firmly apply the movable contacts against the fixed contacts.
  • the rod axes 45 and 46 are both located to the left of a plane passing through the axes 43 and 35 so that the force exerted by the springs 38 acting on the tilting contact carrier 34, and who clearly outweighs the weaker return spring of the operating part 31, tends to push the axis 45 between connecting rod and connecting rod to the left, movement prevented by the presence of the groove 49 of the trigger lever 47, itself immobilized by stop against the pawl spout 58, so that the connecting rod and the rod are braced against the operating part 31, the further rotation of the operating member 31 being prevented by a second stop.
  • one or more of the interrupting or tripping devices concerned namely bimetallic strip 25, magnetic circuit breaker 26, 27, 28, are actuated , so that the pawl 50 will be biased by the action of one of the aforementioned means on its respective actuating finger, namely one of the fingers 54 and 56, any of these actions then causing the ratchet 50 counterclockwise against its return spring 50a.
  • the spout 57 of the pawl releases the spout 58 of the trigger lever 47 ( Figures 16 and 20), which allows the trigger or "break" of the toggle formed by the rod 42 and the rod 44 to be released.
  • the axis 45 can then move to the left (FIG. 16) until it reaches the extreme breaking position (FIG. 17) and the axis 46 between the link and contact carrier 34 is raised, allowing the carrier contact to rotate clockwise and separate the movable contacts 36 from their respective fixed contacts 37, the trigger lever 47 tilting to follow this movement, which also has the effect of keeping the pawl 50 in its tilted position even in the case where the triggering means have ceased to act, due to the presence of the end of the rib 47a of the triggering lever which prevents movement of the pawl in a clockwise direction.
  • the plunger core with its striker 28 and its part 29 will be thrown suddenly to the left from the rest position shown in Figure 10.
  • the ramp of the part 29 comes into contact with the finger 54 of the pawl 50 presented by the large lever 52 thereof, which has the effect of tilting the pawl anti-clockwise, as before, and immediately causing the breakage of the knee brace.
  • the continued brutal advance of the striker 28 and of the part 29 will keep the pawl 50 in its tilted position while the end of the striker 28 strikes the arm 60 of the contact-carrying part 34 (FIG. 12) which is then suddenly overturned, so that the tearing of the movable contacts from the fixed contacts is will find assured.
  • the lowering of the pawl whatever its cause, prevents any action on the operating member 31 from interfering with the contact separation operation or switching the contact carrier back to the closed contact position.
  • the trigger lever 68 is then tilted clockwise by the relay rod 30a and its spout 72 then releases the spout 67 of the intermediate triggering part 61 which can then tilt around its axis, clockwise, under the effect of the spring 64, so that the ramp 63 of the triggering part 61 is quickly tilted downward when coming to the contact of finger 53 of pawl 50 which, pushed counterclockwise, immediately releases the toggle and causes the opening of the contact carriers. Furthermore, the ascent of the axis 46 between the link and the contact carrier caused by the breakage (FIGS.
