Definitions

  • the invention relates to a low-voltage multipole circuit breaker with a molded housing according to the preamble of claim 1.
  • a multi-pole circuit breaker of the kind mentioned is known from document FR-A 2 484 136.
  • this circuit breaker has arcing contacts which open after the contacts main and are thus the only ones to be exposed to the action of the arc, drawn between the arcing contacts, during their separation. This solution is complicated.
  • the present invention aims to allow the realization of a molded case circuit breaker with improved breaking capacity by particularly simple and effective means, and devoid of arcing contacts.
  • an insulating screen is associated with the movable contacts, so as to confine with the fixed contacts an arc-forming chamber open towards the breaking chamber.
  • the insulating screen notably closes the intervals between the various movable contacts, as well as the gap formed between the insulating partitions delimiting the compartments of the different poles and the adjacent movable contacts.
  • the insulating screen is advantageously a single piece molded from a gas-generating material having slots for passage of the contact arms.
  • the central part of the insulating screen extends parallel to the fixed contacts at a short distance from the latter to delimit an arc-forming chamber of low height.
  • the limited volume of the arc chamber ensures a rapid increase in pressure due to the thermal and gas-generating action of the arc.
  • the compressed gases escape to the breaking chamber by blowing the arc which very quickly leaves the contact zone.
  • the rapid initial displacement of the arc also results from a particular conformation of the arc migration tracks constituted by arc horns associated with the contacts.
  • the fixed arcing horn has a boss having a flank parallel to the direction of movement of the movable contact to define a region of small spacing preventing any re-ignition of the arc on the contacts.
  • the arc horns define divergent tracks from the contacts which favor the displacement of the arc which tends to lengthen.
  • the fixed arc horn is preferably made of stainless steel or of refractory material and it extends into the breaking chamber of which it constitutes one of the end plates.
  • the boss of the fixed bow horn limits the initial elongation of the bow in the area adjacent to the contacts.
  • Document DE-B 2 643 433 describes a fixed arc horn having a boss. This boss is flush with the fixed contact and the spacing between the boss and the movable contact is always greater than that between the contacts, on which the arc risks re-striking.
  • the combined action of the insulating screen and arcing horns allows the creation of a circuit breaker with a simplified active part.
  • the contact fingers are simple copper blades articulated on a common axis carried by a support of movable contacts.
  • the movable contact consists of a patch attached to one of the longitudinal edges of the blade which forms with the front edge the movable arc horn.
  • the breaking chamber comprises deionization plates and according to a development of the invention, the bottom of this chamber is closed by a valve arranged as a deflector of the gases escaping from the chamber.
  • the valve opens automatically when there is a significant overpressure in the chamber, the gases flowing outwards along a baffled route.
  • the valve allows the pressure inside the breaking chamber to be controlled and the arc to be extinguished regardless of its intensity.
  • the valve is advantageously constituted by an insulating plate made of a gas-generating material, the side walls of the chamber can also be made of gas-generating material.
  • a low-voltage electric circuit breaker comprises a molded case at the bottom 10 and with a cover 12 in which is housed a mechanism designated by the general reference 14.
  • the electrical part of the circuit breaker comprises input 16 and output 19 terminals, the input terminal 16 being connected to a fixed contact 18 by a conductor 17, attached to the bottom 10 of the molded housing.
  • movable contacts 20 pivotally mounted on an axis 22 carried by a contact support 24, integral a bar 26 for connection between the different poles of the circuit breaker.
  • Movable contacts 20 are connected by braids 28 to a conductor 30 fixed to the output terminal 19.
  • the conductor 30 constitutes the primary winding of a current transformer 72 in the form of a toroid.
  • Springs 32 interposed between the support 24 and the movable contacts 20, provide the contact pressure.
  • the contacts 18, 20 are associated with a breaking chamber 34 with deionization plates 36.
  • the mechanism 14 comprises a handle 38 passing through a lumen 40 of the cover 12 and secured to a support 42, pivotally mounted on a fixed axis 44 carried by flanges 46, secured to the molded housing by screws 48.
  • a fixed axis 44 carried by flanges 46, secured to the molded housing by screws 48.
  • a hook 52 On another fixed axis 50 is articulated a hook 52 whose end 54 cooperates with an attachment 56.
  • On an axis 58 of the hook 52 is articulated an upper link 60 of a toggle joint with axis 62.
  • the lower link 64 of the toggle joint is articulated on an axis 66 carried by the support 24.
  • a tension spring 68 is anchored one by one on the axis 62 of the toggle joint and on the other hand on an axis 70 carried by the support 42 for handle 38.
  • Such a circuit breaker is well known.
  • Manual opening of the circuit breaker is controlled by the pivoting of the handle 38 which causes the toggle joint 60, 64 to break, and the movable contacts to move to the open position.
  • the pivoting in the opposite direction of the handle 38 controls the closing of the contacts 18, 20.
  • a tripping circuit advantageously electronic, controls the unlocking of the latching 56, so to release the hook 52.
  • the pivoting of the hook 52 ensures the automatic opening of the contacts 18, 20.
  • the circuit breaker has 3 poles, each housed in a compartment delimited by longitudinal partitions 74 of the molded housing.
  • the 3 poles are identical and only one of them is described below, more particularly with reference to Figures 2 to 5.
  • On the axis 22 of the support 24 are mounted with limited pivoting five contact arms 76, each consisting of two blades 78 joined and secured, in particular by a movable contact patch 80 welded to the longitudinal edge 86 of the blades 78.
  • the contact arms 76 are extended beyond the hinge axis 22 by a heel 82 cooperating with the the support 24 to limit the pivoting of the contact arms 76 anti-clockwise in the figures, under the action of the contact pressure spring 32.
  • the contact pads 80 are fixed in an intermediate part of the blades 78 between the axis 22 and the front edge 84 of the blades 78.
  • the front edge 84 and the longitudinal edge 86 projecting from the movable contact pad 80 constitutes an arc horn extending opposite a horn d fixed arc 88 associated with fixed contact 18.
  • the fixed contact 18 comprises a range of contacts common to all of the movable contacts 20 of the pole and the fixed arcing horn 88 is a plate extending between the fixed contact 18 and the breaking chamber 34 of which it constitutes one of the end plates.
  • the fixed arcing horn 88 has, in its part adjacent to the contact 18, a planar part 90 situated in the plane of the fixed contact 18.
  • the planar part 98 is extended by a part folded into a boss 92 having a side extending in the direction of displacement of the movable contact 20.
  • the movable arcing horn 86 forms with the flat part 90 of the horn d 'fixed arc 88 a divergent track oriented towards the breaking chamber 34.
  • the folded part 92 of the fixed arc horn 88 is very close to the front edge 84 of the blades 78. The arc drawn, during separation contacts 18, 20, first moves on the divergent tracks 86, 90, to quickly anchor on the boss 92 and the facing edge 84.
  • the movable contact 20 is associated with a screen 94 made of a gas-forming molded insulating material.
  • the screen 94 consists of three parts, in this case lamellae 96 inserted in the separation intervals of the contact arms 76, a front part 98 extending the front edge 84 of the blades 78 and a rear part 100 disposed at the axis 22 of articulation of the contact arms 76.
  • the screen 94 has notches 102 for clipping onto the axis 22, the screen being rigidly or with little play secured to the movable contact 20.
  • the lamella assembly 96 and contact arm 76 forms with the front part 98 of the screen 94 a partition cooperating with little play with ribs 104 provided on the lateral partitions 74.
  • This partition 96, 98 extends in the direction of movement of the movable contact 20 to ar-Hère of the front edge 84 of the blades 78.
  • the rear part 100 of the screen 94 cooperates with little play with the side partitions 74 and with the bottom 10 of the case molded at the moment for separating contacts 18, 20 , in order to close off the space disposed behind the contacts 18, 20.
  • the lower edge 105 of the strips 96 extends substantially parallel to the fixed contact 18 in the closed position of the contacts, with slight withdrawal of the longitudinal edges of the blades 78, carrying the contact pads 80.
  • the contacts 18, 20 are housed in the closed position in a space constituting an arc-forming chamber, delimited at the lower part by the fixed contact 18 and the wall 10, at the upper part by the blades 78 and the interposed lamellae 96 and at the right part, in FIG. 3 by the part 100 of the screen 94.
  • This formation chamber d arc is open on the side of the cutting chamber 34 by a passage confined by the boss 92 and the front part 98 of the screen 94.
  • the combined arc blowing action due to the insulating screen 94 and the configuration of the arcing horns 86, 88, allows the production of a circuit breaker with high breaking capacity, devoid of arcing contacts. . It is clear that the intervention is applicable to a mobile contact having a different number of contact arms 76, in particular a single mobile contact arm.
  • the interrupting chamber 34 is closed at its rear part opposite the contacts 18, 20, by a plate or a pair of plates 106, made of an advantageously gas-generating insulating material.
  • the plate 106 is fixed by its upper edge 108 to the carcass of the cutting chamber 34 and it has a certain elasticity or a possibility of pivoting to move away from the ends of the sheets 36 by clearing a passage 110 for exhaust of the gases of the breaking chamber 34.
  • the breaking chamber 34 is closed by the plate 106 authorizing a rise in pressure sufficient to extinguish the arc.
  • the rise in pressure causes the plate 106 to deflect, allowing gases to escape and a pressure limitation in the cutting chamber 34.
  • the plate 106 acts as a gas deflector towards the bottom 10 of the molded housing, these gases subsequently escaping through orifices 112, formed in the cover 12.
