Definitions

  • the invention relates to a breaking chamber of a high-voltage low-voltage circuit breaker intensity.
  • circuit breakers there is a particular difficulty when seeks to cut a current under a relatively high voltage, of the order of 600 Volts effective in single-phase, or 1000 Volts effective three-phase, with a fairly low intensity, of the order of 5 to 10 times the rated current of the circuit breaker.
  • Document EP 0 306 382 describes a multi-pole circuit breaker with molded insulating housing meeting this requirement, containing a control mechanism coupled to a switching bar, so as to ensure the opening and closing of the assembly of the circuit breaker poles.
  • Each pole has a fixed contact member, a movable contact and an arc extinguishing chamber.
  • the fixed contact member includes a fixed conductive range of current supply bearing on the bottom of the housing, main fixed contacts and a fixed arcing contact.
  • the mobile contact member comprises a fixed conductive current supply range also bearing on the bottom of the housing, and a contact system having a plurality of identical main contacts, divided into two series of the same number on either side of a movable arcing contact extending longitudinally along the center line of the pole, the length of the arcing contact movable being greater than the length of the movable main contacts.
  • Bedroom arc extinguishing is arranged above the first range and includes a stack of separators constituted by metal sheets for deionizing the arc, each sheet having a V-shaped notch.
  • a pair of lower and upper arc horns frames the stacking of sheets in the extinguishing chamber.
  • the lower bow horn is secured to the upper face of the first track with the interposition of an insulating screen, by means of three screws which ensure the passage of current between the bow horn and the beach.
  • the three screws are arranged at the vertices of an isosceles triangle, one of the screws being arranged along the center line of the pole near an edge of the insulating shield and a wall of the cut-off gases to the outside and the other two being near the main stationary contacts.
  • the width of the lower bow horn decreases in the direction of the migration of the arc towards the central screw, and the two other screws are on both sides of the fixed arcing contact, and in the vicinity of the corresponding fixed main contacts.
  • the arc arises in the contact separation zone arc located along the center line of the pole and then develops in the central area from the room.
  • the arc migrates towards the central screw which stabilizes the root of the arc.
  • the distance between the arcing contacts becomes greater than the distance between the main contacts, resulting in a reclassification of the arc at the contacts main on one side of the room.
  • the arc then develops on a second different path, along one side of the chamber, gradually refocusing, and by encountering along its path cold surfaces where absorption occurs efficient of the energy favorable to the extinction of the arc.
  • document FR 2 604 026 describes a circuit breaker, the lower arc horn of which widens from its front part close to the contacts to its rear part close to the bottom of the extinguishing chamber.
  • the enlarged posterior part constitutes a collecting part whose surface is smaller than the section of an arc root for an arc which would be formed with a constant electric current density corresponding to the breaking current nominal.
  • the objective here is to bring the arc to the collecting part and to stabilize it there.
  • the arc stabilized then develops mainly in the middle part of the chamber.
  • a such a configuration is only effective if the longitudinal dimension of the chamber, i.e. its depth between the fixed contact zone and the rear wall of the chamber serving gas extraction is important. The width of the room can be reduced because it is not used to extinguish the arc.
  • the invention therefore aims to improve the performance of a low multipole circuit breaker high rating voltage, including a circuit breaker to be adapted to cut nominal current greater than 1000 amperes effective, at a high voltage, of the order of 600 Volts in effective value per phase. It aims in particular to reduce the volume of the room necessary to guarantee the breaking of a current under high voltage, by reducing its depth for a given width. More specifically, it aims to make full use of the chamber volume when the chamber is wide and shallow and / or tall scaled down.
  • the invention finds a particularly effective application in terms of reduction of volume if in each part of the chamber delimited by the longitudinal median plane, said point is also located in relation to the rear wall at a distance which is less than a quarter of the distance between each of the side flanges. We are thus assured that the arc will fully use the volume of material made up of the separators.
  • the invention preferably applies to a relatively wide pole, in in particular a pole whose distance between the contact zone of the fixed contact member and the bottom wall of the chamber is less than the distance between the side flanges of the bedroom. It also applies to a pole whose arc horn is less than a length, measured in the longitudinal median plane, which is less than the largest width of the posterior part of the bow horn, measured along an axis perpendicular to the plane longitudinal median.
  • the metal plates of the separators have an anterior edge provided an asymmetrical notch directed towards one or the other of the lateral flanges.
  • the periphery protrudes towards the inside of the chamber relative to the posterior part of the bow horn or flush with the posterior part of the bow horn.
  • the projecting circumference allows a significant degassing, which contributes strongly creating the desired effect of developing two parallel arcs or an arc oscillating laterally in the two lateral parts of the chamber.
  • a low-voltage multi-pole power circuit breaker 10 comprises a molded insulating housing 12 containing a type 14 control mechanism known, provided with a transverse switching bar 16 common to all of the poles, swiveling in bearings formed in the housing 12.
  • Each pole has a fixed contact member 20, a movable contact member 22 and an extinguishing chamber arc 24 located near the fixed contact member 20.

  • the body of fixed contact 20 further comprises two main contact strips 28 (FIG. 2) fixed directly to the current supply range 26 and a median arcing contact 30.
  • the arcing contact 30 is fixed to the current supply range 26 in an intermediate zone between the bars 28 and the chamber 24.
  • the arcing contact 30 extends towards the inside of the chamber 24 by a conductive lower arc horn 34 described in detail below.
  • the current supply range 26, the bars 28, the arcing contact 30 and the arcing horn 34 are made of various conductive metallic materials, and have the same potential.
  • the arcing contact 30 and the bars 28 together constitute a contact area 36 intended for ensuring electrical contact with the movable contact member 22.
  • the movable contact member 22 comprises a fixed conductive supply path current 40, a support cage 42 pivotally mounted about an axis 44 fixed relative to the housing 12 and a plurality of main contact fingers 46 (Figure 3) placed on the side and on the other side of a middle arc contact finger 48.
  • the contact fingers 46, 48 pivot around a common geometric axis 50, fixed relative to the cage 42, and are recalled to the fixed contact member by contact pressure springs 52.
  • a connecting rod coupling 54 is used for coupling between the cage 42 of the movable contact member 22 and a crank 56 of the switching bar 16 of the mechanism 14.
  • Each finger main 46 includes a contact pad 58, intended to ensure contact with the corresponding contact strip 28 of the fixed contact member 20 when the appliance is in the closed position shown in Figure 1, and a lug 60 protruding beyond from the contact pad to the extinguishing chamber 24.
  • the arcing contact finger meanwhile has a movable arcing contact 62 des intended to ensure contact with the fixed arcing contact 30 of the fixed contact member 20 when the device is in the position closed shown in Figure 1, and a lug 64 protruding beyond the pellet of contact towards the extinguishing chamber 24 with a shape identical to that of the pins 60.
  • the contact fingers 46, 48 are electrically connected to the current supply range 40 through braids 49.
  • the extinguishing chamber 24 comprises two lateral flanges 68 of insulating material, which are parallel to the section plane of Figure 1 and located equidistant from both sides of it, so that the cutting plane constitutes a longitudinal geometric plane median 70 of room 24 and the pole.
  • a rear wall 72 of gas exhaust is arranged at the rear of the chamber, perpendicular to the lateral flanges 68. This wall 72 has one or more orifices 74 for exhausting the breaking gases.
  • a front opening 76 is arranged near the contact zone 36, opposite the rear wall 72.
  • Separators 78 constituted by flat metal plates extend perpendicular to the median longitudinal plane 70 of the anterior opening 76 at the rear wall 72.
  • the dividers 78 are arranged at a distance from each other so as to leave the possibility of gas circulation between the front opening 76 and the rear wall 72.

Each plate 78 has an anterior stop 80 for capturing the electric arc, which has approximately a concave U-shaped curved shape in the plane of the plate or in V with a narrower and asymmetrical notch 82. The separators 78 are stacked so that the notches 82 are alternately on a lateral side and the other from room 24.
  • the lower bow horn 34 intended to receive the root of the bow when the bow extends from the fixed arcing contact 30 towards the interior of the chamber 24, has a part rear 84 located inside the chamber, and an intermediate portion 85 connecting the part posterior to the fixed arcing contact 30.
  • the width of the posterior part 84 that is to say its largest dimension measured along an axis perpendicular to the plane longitudinal median 70 of the chamber, is important while the intermediate part 85 constitutes a narrower section.
  • the rear part 84 has two lateral surfaces constituting reception areas 86 for the root of an electric arc developing in room 24.
  • reception area 86 and the side flange located in the same half-space delimited by the longitudinal median plane 70 is less than half the distance between the flange 68 and the median plane 70, and therefore less than a quarter of the width of the chamber measured between the flanges 68.
  • the reception areas 86 are also relatively close to the rear wall 72 of the chamber.
  • the horn lower arc 34 has in its rear part 84 and on each lateral side of the chamber at least one point located, relative to the lateral flange located on the same side of the chamber, at a distance less than a quarter of the width of chamber 24 and located, by relative to the posterior wall 72, at a distance less than a third or a quarter of the width of the chamber 24.
  • the lower bow horn 34 is fixed on a bottom constituted by a plate of material insulator 90, in this case polyamide 6-6 loaded with 30% glass fiber.
  • the part of the plate 90 not covered by the bow horn extends to the flanges 68 and the wall posterior 72. It has a periphery 92 forming a protruding shoulder in the chamber and flush with the periphery of the rear part 84 of the bow horn.
  • the periphery 92 can project towards the inside of the chamber until a height greater than that of the posterior part of the bow horn.
  • Around 92 has a rounded shape of C which matches the shape of the rim of the rear part 84, and in particular reception areas 86, so as to constitute a separation between the posterior part 84 and the posterior wall 72 of the chamber on the one hand, and between the part posterior 84 and the lateral flanges 68 on the other hand.
  • the posterior part 84 of the horn arcing is electrically connected to the field 26 only through the arcing contact 30, and the plate 90 constitutes a continuous solid insulator between the rear part 84 and the pad 26.
  • An upper bow horn 96 intended to receive the head of the bow at the end of opening of the movable contact member 22, is constituted by a metal plate perpendicular to the median longitudinal plane 70, supported by the lateral flanges.

  • the main contact fingers 46 pivot very slightly around the axis of rotation 50, counterclockwise of a watch in FIG. 1, under the effect of the contact pressure springs 52, while remaining in contact with the bars 28. Then they meet a stop of the cage 42, and are driven in solidarity with the cage 42 rotating clockwise around the axis of rotation 44, so that they separate from the bars 28.
  • the movement of the arcing contact finger 48 is similar, but offset in time, because the spatial offset between the bars 28 and the fixed arcing contact 30.
  • the arcing contact finger 48 is still in contact with the fixed arcing contact 30. All of the current flowing between the pads 26, 40 then passes through the arcing contacts 30, 62. In a second phase, the contact finger arc 48 in turn encounters a stop of the cage 42 which drives it solidly with the cage 42 in the latter's rotational movement around the axis of rotation 44 of the cage, clockwise, so that separation occurs from the arcing contact finger 48 and the fixed arcing contact 30. An arc arises between the arcing contacts 30. Due to the loop of current formed in range 26 and plate 32, the root of the arc migrates rapidly towards the bottom of the chamber 24, while the head of the arc remains on the lug 64 of the finger contact 48.

  • the arc, penetrating in chamber 24, divides more or less in contact with the separators 78 in an arc elementary, each elementary arc constituting an electrical connection in series between two separators 78 adjacent to or between each arc horn 34, 96 and the separator 78 making it face.
  • the arc root tends to move to one or other of the lateral reception areas 86 of the bow horn lower.
  • the root of the arc causes the rim of the periphery 92 to be ablated in gas-generating material with a significant emission of gas, especially hydrogen.
  • This nearby gas emission bow root causes constriction of the bow root and prevents the latter to stabilize definitively on the lateral reception area 86 in question.
  • Two hypotheses can be put forward: according to a first hypothesis, the root of the arc located on one of the reception areas 86 would be expelled from emits gas around 92, and migrate laterally to the other area reception 86 where the same phenomenon would occur again, so that we would witness a oscillating movement of the root of the arc between the two lateral reception areas 86. According to another hypothesis, the gaseous emission would cause necking of the root of the arc, such that a re-plating would take place at the other reception area 86, the two arches remaining simultaneously in the room.
