Definitions

  • the handle is supported by a metal cradle or bracket in the shape of an inverted U, pivotally mounted on a fixed axis subject to the plates of the mechanism.
  • the trajectory of the joystick has a small pivot radius due to the presence of the material axis of the cradle inside the housing.
  • the switching bar and / or the trigger bar are generally arranged outside the trajectory of the lever.
  • the object of the invention is to remedy the aforementioned drawbacks, and to allow the realization of a compact case circuit breaker equipped with a simple mechanism allowing reduced friction of the moving parts of the moving assembly.
  • the base of the lever moves along a ramp combined with a fixed guide member integral with the mechanism, the ramp being arranged to precisely determine the trajectory and the pivot axis fictitious controller.
  • the fixed guide member is formed by the plates of the mechanism, each plate comprising a ramp, either curvilinear or inclined in the case of a pivoting movement of the lever with a fictitious pivot axis, or rectilinear and parallel to the bottom of the housing. in the case of a sliding movement of the lever.
  • Rolling members can be interposed between the underside of the base and the plates to reduce the friction forces generated during movement of the lever on the corresponding ramps.
  • the ramps can be shaped on the upper edges of the plates, each rolling member being formed by a roller having an axial length slightly greater than the transverse spacing formed between the plates.
  • the absence of an additional articulated support part for the lever makes it possible to minimize the friction of the movable members of the mechanism.
  • the fictitious axis of rotation of the joystick can be located outside the case, which makes it possible to increase the pivoting radius of the joystick. This radius is perfectly defined by the dimensional characteristics of the ramps. It follows that the opposite ends of the base of the lever respectively cover the switching rod and the trip bar when the lever is in the extreme positions of the pivoting stroke. The size of the circuit breaker box is thus reduced to a minimum.
  • the pivot pin of the toggle rests on a cam of the release lever. This results in a variation of the opening stroke of the contact arms due to a different rotation of the bar occurring during manual opening or during opening by automatic triggering. The stroke of the contact arms is greater in the event of tripping.
  • this variation of the opening stroke is used to actuate, by means of the bar, the various electrical auxiliaries arranged on either side of the mechanism.
  • a low-voltage three-pole circuit breaker comprises a housing 10, parallelepipedal in molded insulating material containing an operating mechanism, designated by the general reference 12.
  • the three poles are housed in juxtaposed compartments located in the lower part of the shoemaker 10 and the mechanism 12 is arranged above the central pole in the upper part of shoemaker 10.
  • Each pole includes a pair of separable contacts 14, 16, an arc extinguishing chamber 18 and a thermomagnetic trip device 20.
  • the fixed contact 14 is carried by an end conductor 22 extended externally by a first contact pad 24 making projection from the side face 25 of the boot 10.
  • the movable contact 16 is arranged at the end of a vertical contact arm 26 secured by a spring 27 to a switching bar 28 common to the three poles.
  • the insulating bar 28 for supporting the contact arms 26 is mounted with limited rotation between the open and closed positions of the circuit breaker and extends transversely above the poles in the upper part of the housing 10 in a direction perpendicular to the arms 26 mobile contacts.
  • the arc extinguishing chamber 18 is constituted by a stack of metal separators or deionization sheets 30 extending perpendicularly to the bottom 32 of the case 10.
  • the second contact pad 34 of each pole exits from the opposite side face 36 of the case 10, and is electrically connected to the thermothermal trip device 20, the latter being arranged between the arc extinguishing chamber 18 and the side face 36.
  • electrical connection of the contact arm 26 with the second contact pad 34 is effected by means of a flexible conductor formed by a braid 38, surrounded by an insulating sheath, not shown.
  • the insulation of the braid 38 constitutes a functional insulation of the mechanism 12 with respect to the active parts of each pole.
  • the mechanism 12 is mounted above the central pole, between two spaced plates 40, 42 extending parallel in the longitudinal direction of alignment of the contact pads 24, 34.
  • the switching bar 28 is actuated by means of a knee lever 44 comprising a lower link 46 and an upper link 48 articulated on a pivot axis 50.
  • the knee switch 44 cooperates on the one hand with a lever 52 for manual control projecting from an opening 53 of the cover 54, and d on the other hand with an automatic hook or trigger lever 56 pivotally mounted on a pivot 58.
  • the lower link 46 is mechanically coupled to the switching bar 28 and the upper link 48 is articulated on an axis 60 of the trigger lever 56.
  • the mechanical connection between the toggle joint 44 and the lever 52 takes place in an elastic manner by means of a tension spring 62, one of the ends of which is anchored to the pivot axis 50 of the knee llère 44 and the other end of which is attached to a lug secured to the lever 52.
  • the trigger lever 56 comprises a hooking nose 64 cooperating in the armed position with a lock 66 of a trigger bar 68 made of insulating material, common to the three poles.
  • the trigger bar 68 extends above the magnetothermal trigger 20 of each pole in a direction parallel to the switching bar 28, and is mounted with limited rotation between an armed position for locking the hooking nose 64 of the lever 56 by the latch 66 and a triggered position releasing the lever 56 by unlocking the latch 66.
  • the transition from the armed position to the triggered position of the rotary bar 68 operates clockwise and is controlled either by the thermomagnetic trip device 20 in the presence of an overload or short-circuit current, or by an auxiliary trip device, in particular an undervoltage relay so as to cause the automatic tripping of the mechanism 12 and the opening of the contacts 14, 16 of the three poles by rotation of the switching bar 28 anticlockwise.
  • the latch 66 of the trigger bar 68 is biased in the armed position by a return spring (not shown).
  • the lever 52 is provided with an elongated base 70 located inside the housing 10 between the mechanism 12 and the cover 54.
  • the curved underside 72 of the base 70 is supported on a fixed guide member 73 formed by the upper edges of the two plates 40, 42 of the mechanism 12 with the interposition of two rollers 74, 76 (see fig. 4 and 5).
  • Each plate 40, 42 is equipped with two ramps 78, 80 curvilinear or inclined on which the rollers 74, 76 roll during the movement of the lever 52.
  • the dimensional characteristics of the ramps 78,80 make it possible to precisely determine the radius of the stroke and the pivot point M of the lever 52, the point M being the trace of a fictitious axis of rotation located in FIG.
  • the position of the pivot point M of the lever 52 depends on the radius of curvature of the ramps 78, 80, and end-of-travel stops 82, 84 delimit each ramp 78.80 to control the extreme positions of the pivoting stroke of the lever 52.
  • the presence of the rollers 74, 76 reduces the frictional forces generated during the movement of the lever 52, each roller 74, 76 having an axial length slightly greater than the transverse spacing d formed between the plates 40, 42 (FIG. 4).
  • the point M, non-material, of pivoting of the lever 52 can be outside the housing 10, which makes it possible to minimize the height of the case 10 between the bottom 32 and the cover 54.
  • the ramps 78, 80 of the upper edges of the plates 40, 42 are rectilinear, extending parallel to the bottom 32 of the housing.
  • the base 70 is also rectilinear and cooperates with the ramps to impose a translation movement limited to the handle 52 during its travel between the open and closed positions.
  • the lower link 46 of the toggle joint 44 of the mechanism 12 is formed by a rectangular open loop of steel wire of circular section.
  • the ends 88 of the open branch 90 of the loop are engaged in an opening 92 of the switching bar 28.
  • the opposite branch 94 of the lower link 46 is positioned in a semi-open notch 96 formed in a U-shaped stirrup 98 constituting the upper link 48.
  • the spring 62 for triggering the mechanism 12 is hooked between the branch 94 and the lever 52 and maintains the branch 94 at the bottom of the notch 96, so as to form the pivot axis 50 of the toggle joint 44.
  • FIGS 8 and 9 show another embodiment of the toggle 44 in which each link 46, 48 is shaped into a U from a steel wire of circular section.
  • One 100 of the lateral branches of the lower link 46 is held by the tension spring 62 in a crescentally deformed part 102 of the upper link 48.
  • the pivot axis 50 of the toggle joint 44 moves along a cam 104 of the curved lower edge of the trigger lever 56, said edge being arranged between the pivot 58 and the hooking nose 64 opposite the axis 60 of articulation of the upper link 48.
  • the cam 104 of the lever 56 is delimited by two notches 106, 108 serving as stops for the axis 50 of the toggle joint 44 when the contacts 14, 16 of the poles are respectively in closed and open position.
  • the trigger lever 56 In the closed F position (FIG. 1), the trigger lever 56 is locked in the armed position by the lock 66, and the axis 50 of the toggle joint 44 is positioned in the first notch 106 of the cam 104.
  • the circuit breaker is reset by manual movement of the handle 52 clockwise from position 0 / D to the reset position R close to position 0 so as to ensure that the trip lever is hooked 56 to the lock 66.
  • the closing of the contacts of the circuit breaker (FIG. 1) then takes place by a reverse rotation of the handle 52 actuated manually towards the position F.
  • the control auxiliaries are formed by auxiliary triggers, in particular of the voltmetric type with undervoltage MN and / or with current emission MX intended to cause the unlocking of the lock 66 to trigger the mechanism 12 following the absence of voltage on the network or to a remote control opening the circuit breaker.
  • the variation in the opening stroke of the contact arms 26 occurring by a different rotation of the bar 28, depending on the type of manual or automatic control on fault, is advantageously used to actuate the various electrical auxiliaries.
  • the switching bar 28 for this purpose comprises a projection 110 ( Figures 10 and 11) or boss arranged in the vicinity of each auxiliary.
  • the projection 110 of the bar 28 cooperates in positinn O / D of the lever 52 with a transmission lever 112 intended to actuate the change-over contact 114 of the second system of contacts SD for remote signaling of a trip on fault.
  • the projection 110 associated with the first auxiliary contact system 0F would actuate the corresponding change-over contact 114 if the lever 52 was in the 0 position for manual opening.
  • the change-over contact 114 of the first system 0F is therefore controlled prior to that of the second system SD because of the different opening travel of the bar 28 in the direction of the arrow f.
  • an auxiliary release MN or MX comprises an angled control lever 116 pivotally mounted on an axis 118. One end of the control lever 116 cooperates with a protrusion 120 of the trigger bar 68, and the the opposite end is in contact with the transmission lever 112.
  • the control lever 116 pivots clockwise and drives the bar 68 to the triggered position.
  • the lever 52 arrives in intermediate position 0 / D, the projection 110 of the bar 28 actuates the levers 112, 116 in the direction of the arrows f to ensure automatic resetting of the auxiliary release MN or MX. This automatic rearming by the bar 28 is impossible in position 0 of the lever 52.
