Definitions

  • the protective circuit breakers can be single-pole or multi-pole with two, three or four poles.
  • the mechanism, the switching bar, the contact parts, the breaking chambers, and the trip devices A range of circuit breakers requires a multitude of variants for this purpose. The manufacture of such a range poses assembly problems, because the parts or elements to be adapted always have the same shapes or structures, and are not easily interchangeable.
  • the object of the invention is to provide a multipole circuit breaker having a modular architecture allowing the construction of several types with modules with standard dimensions.
  • the bar On the side of the base, the bar is positioned in two lower half-bearings formed by the juxtaposition of the recesses of the spacers, and of the notches provided in the large lateral faces of the bulbs.
  • the upper half-bearings of the bar On the cover side, the upper half-bearings of the bar are formed by curved bearing surfaces integral with the plates of the mechanism.
  • a pole of a multipolar circuit breaker 10 with molded insulating housing 12 comprises a single-pole breaking module 14, formed by a one-piece bulb 16 made of molded plastic, and having the shape of a rectangular parallelepiped.
  • the bulb 16 comprises a bottom 18, a front face 20 having an orifice 22 for the passage of the movable contact 24, two large parallel lateral faces 26, 28 and two small parallel faces 30, 32 for connection.
  • the triggering device comprises a trigger module 46, the one of which in FIG. 1, being formed by a magnetothermal trigger, equipped opposite the pad 44, with a fourth contact pad 48 forming part of the other terminal 50 of pole connection.
  • the trip module 46 is inserted in series in the pole with the contacts 34, 36, 24 of the cut-off module 14. In the closed state of the circuit breaker, the current enters through the input terminal 40, and flows successively through the conductor 35, the fixed contact 34, the movable contact 24, the other fixed contact 36, the conductor 37, the ranges 42, 44, the trigger 46, and the output terminal 50.
  • the triggering device further comprises a trigger bar 52 mounted with limited rotation between an armed position and a triggered position as a function of the position of the actuator of the trigger 46, for example the bimetallic strip 54 or the pallet 56.
  • the rotary bar 52 is moved to the triggered position as soon as the current flowing in the pole exceeds a predetermined threshold.
  • the trigger bar 52 also cooperates with a latch 58 for hooking a control mechanism 60 with toggle joint 62 and to lever 64.
  • the mechanism 60 is common to all of the poles, and is housed in the housing 12 between two metal support plates 66, 68, only the handle 64 being accessible from the outside by passing through a lumen 65 passing through the housing 12, to circuit breaker control 10.
  • the mechanism 60 comprises a trigger hook 70 pivotally mounted on the plates 66, 68 parallel, the free end of the hook 70 being engaged with the latch 58 in the armed position.
  • a connecting rod spring 72 is anchored between the axis 74 of articulation of the toggle joint 62, and an axis 76 integral with the base 78 of the lever 64.
  • the lower link 80 of the toggle joint 62 is coupled to a protuberance 81 of a switching bar 82 serving to support the movable contacts 24 of all the poles.
  • the switching bar 82 is made of insulating material and extends parallel to the trigger bar 52 in the transverse direction of the poles.
  • the upper link of the toggle joint 62 is articulated on the trigger hook 70.
  • the unlocking order of the lock 58 can come from the magnetothermal trip module 46, or from an auxiliary trip device, in particular with a lack of voltage MN, with emission of current MX, differential, etc.
  • the cut-off module 14 additionally contains two arc extinguishing chambers, one of which 84 is shown in FIG. 1.
  • the outlet from the chamber 84 is in communication with an opening 86 for exhaust of the cut-off gases towards the outside of the bulb 16.
  • the insulating housing 12 of the circuit breaker 10 is composed of a base 88 on which is attached from above a cover 90 and front plate 92 closure.
  • the interior of the base 88 is subdivided by intermediate spacers 94, 95 into several compartments 96, 98, 100 juxtaposed for housing the different poles.
  • the two lateral compartments 96 and 100 are shown empty, while the central compartment 98 is illustrated with a bulb 16 of a cut-off module 14 installed in the left-hand part, and a trigger module 46 in the right side.
  • the magnetothermal trigger module 46 can be replaced by another trigger module 46 a, for example of the electromagnetic type with a wide range for setting the trigger threshold, as described in French patent FR 2639 148.
  • the switching bar 82 shown in detail in FIG. 4, is equipped with three movable contact assembly 24 in the form of forks, distributed at regular intervals along the transverse direction of the bar 82.
  • the two intermediate sections of the bar 82 each have a cylindrical bearing surface 102, 104 provided in the central zone with a centering ring 106, 108.
  • each bulb 16 includes a pair of U-shaped notches 110, 112, oriented on the side of the front face 20.
  • the upper edges of the spacers 94 and 95 of the base 88 which are provided with a pair of concave recesses 114, 116, aligned with the respective notches 110, 112 of the bulbs 16 in the transverse direction.
  • the spacers 94, 95 also have elongated slots 118, 120 extending in the longitudinal direction so as to provide small separation intervals between the compartments 96, 98, 100.
  • the coupling of the protuberance 81 of the bar 82 to the lower link 80 of the mechanism 60 makes it possible to obtain the mechanical actuation module 122 of FIG. 3.
  • the two parallel and metallic plates 66, 68 of the mechanism 60 are provided with positioning lugs 123, 124 bearing on the spacers 94, 95 when the cover 90 is placed on the base 88.
  • the trigger bar 52 made of molded insulating material, comprises two end pieces 126, 128 cylindrical, two bearing surfaces 130, 132 cylindrical intermediates, a pin 134 for actuation intended to be controlled by a trigger auxiliary, and a lug 136 for the lock 58.
  • the underside of the cover 90 (FIGS. 2 and 8) comprises on the opposite edges two support tabs 138, 140 which are elastic and capable of receiving the two end pieces 126, 128 by clipping to ensure prepositioning of the trigger bar 52 on the cover 90
  • the latch 58 is also secured to the underside of the cover 90, preferably in the middle zone to cooperate with the control lug 136 associated with the trigger bar 52.
  • breaking modules 14 either single or double breaking, or with one or two arc extinguishing chambers equipped with a number of suitable separators. breaking capacity of the circuit breaker.
  • connection pads 38, 42 are constant for all types of modules 14.
  • the mechanical actuation modules 122 are also adaptable to the power of the circuit breaker 10, since there are switching bars 82 of different diameters, and mechanisms 60 with springs 72 for connecting rods of specific hardnesses.
  • the circuit breaker 10 can be manufactured by an automatic assembly machine, after selection of the standard modules 14, 46, 46 a, 122 to be incorporated in the base 88 and cover 90.
  • the circuit breaker 10 is formed by the association of a first sub-assembly A comprising the base 88 containing the cut-off and tripping modules 46 of the different poles, and a second sub-assembly B constituted by the cover 90 and faceplate 92 assembly, to which the mechanical actuation module 122, the trigger bar 52, and the latch 58 are related.
  • the rotary mounting of the switching bar 82 takes place at the junction plane of the two sub-assemblies A, B.
  • the bearing surfaces 102, 104 are positioned between two lower half-bearings formed by the recesses 114, 116 of the spacers 94, 95 and the aligned notches 110, 112 of the bulbs 16, and two upper half-bearings formed by second curved bearing surfaces 144, 146, formed in the lower edges of the plates 66, 68 of the mechanism 60.
