Definitions

  • the present invention relates to a current switching device comprising in a housing, at least one pole constituted by at least one fixed contact cooperating with a movable contact capable of being moved, in the breaking chamber, relative to said fixed contact, under the action of at least one triggering mechanism.
  • the object of the present invention is to provide a new arrangement of the interrupting chamber envelope associated with a pair of contacts in order to obtain advantages both from an electrical point of view and from the point of view of industrialization and assembly of the components.
  • This arrangement is achieved simply by the one-piece housing without independent base and by an insulating part serving as support for a conductor connecting the fixed contact to the connection terminal and possibly other electrical components.
  • the invention makes it possible to obtain good insulation between phases (leak lines, breaking gas, etc.). It allows the arc blowing means to be used (magnetic U, turns, etc.) by simply isolating them from the other elements of the phase on which they are placed and from the other phases. It allows the use of a different insulating material for the switching chamber and for the housing. It makes it possible to obtain that the breaking chamber associated with a pole is easily isolated from the breaking chamber of another pole.
  • the invention makes it possible to reduce the number of parts, in particular in the case of the use of arc blowing means. It makes it easier to mount the parts constituting the breaking chamber. It also allows easy mounting of the magnetothermal trip elements. It also allows easy mounting of a removable crew carrying the movable bridges. It makes it possible to produce a one-piece housing without an independent base, which provides good electrical insulation as well as good mechanical resistance.
  • the device is characterized in that the housing has a fixing base secured to isolation partitions constituting a channel delimiting the breaking chamber and that said channel of the housing cooperates with a closing drawer made of material. insulation carrying an electrical conductor which connects the fixed contact to the connection terminal, the assembly consisting of the housing and the driver carrier closing drawer constituting the breaking chamber.
  • the housing forms, for each pole, a channel adapted to receive two conductor carrier closing drawers, these two drawers being arranged on either side of a contact carrier module comprising at least one contact bridge mobiles cooperating with said fixed contacts.
  • each drawer consists of a driver-carrying apron and two side walls providing an internal chamber opening into the channel on the side of the central part, these walls being inserted between two partitions so as to be adjacent to them .
  • each drawer has a transverse dividing partition defining, on the side of the central part, the breaking chamber and, on the outside, a gas decompression chamber.
  • the two drawers associated with the same pole fit into two opposite channels of the housing, in translation movements of opposite directions.
  • each of the drawers has arc blowing means isolated between the drawer and at least one partition of the housing.
  • the conductor carried by a drawer has two arc blowing loops each pressed against a lateral face of the drawer opposite a partition of the housing and joining on a part carrying the fixed contact and positioned in the drawer chamber forming the breaking chamber.
  • the part of the conductor carrying the fixed contact is extended in the chamber of the drawer by a tab constituting the deflector on which the arcs develop.
  • the switch device illustrated in the drawings is a multi-pole protective device of the contactor-circuit breaker type. Alternatively, it could be unipolar.
  • the apparatus comprises a one-piece housing 1 produced by molding in electrically insulating material (plastic).
  • the bottom or mounting base 11 of this housing has a groove 12 cooperating with retractable clip elements to ensure the fixing, by snap-fastening, of the device on a standardized profile.
  • This bottom 11 has no opening.
  • the base 11 for fixing the housing is directly integral with external partitions 13 and internal isolation partitions 18. They constitute, two by two with the bottom 11, channels 14 or 15 delimiting the breaking chambers. These partitions 13 and 18 extend perpendicular to the bottom or flat base 11 and parallel to one another (in a direction marked QQ ′ in FIG. 3). Channels 14 and 15 are aligned along axes parallel to QQ ′ and extend on either side of a plane PP ′.
  • Each channel 14 or 15 cooperates respectively with a drawer 2 or 3 which, on the one hand, delimits the breaking chamber 23 or 33 respectively with the housing and which, on the other hand, carries a conductor 4 or 5 respectively.
  • Each pole of the device has two fixed contacts 41 and 51 and a bridge 63 of mobile contacts 61 and 62.
  • the mobile contacts 61, 62 move in translation relative to the fixed contacts, perpendicular to the line passing through these fixed contacts.
  • the plane of displacement and symmetry of the movable contacts is marked PP ′.
  • Each fixed contact 41 or 51 of the same pole is carried by a drawer 2 or 3 respectively fitting into a channel 14 or 15 of the housing.

  • Each terminal 48 or 58 is mounted on the drawer 2 or 3 and is intended to be connected to a power line.
  • the two drawers 2 and 3 of the same pole fit into the two opposite and aligned channels 14 and 15 respectively of the housing. These channels 14 and 15 of a pole open to the outside through two openings on the opposite sides of the housing. These two drawers 2 and 3 fit into the housing 1 by translational movements in opposite directions, towards the plane PP ′, and parallel to a direction marked QQ ′ (FIG. 3), orthogonal to PP ′ and parallel to the bottom of the housing.

  • the movable armature 101 of the electromagnet is subject to a return spring and acts via a button 91 and / or another control.
  • the movable armature 101 of the electromagnet acts on a movable spreader 19, articulated around an axis 191 on the housing and actuating the movable support 64 of the module 6.
  • This spreader has fingers moving in lateral notches 69 of the support 64 to move it and operate the contacts.
  • the partitions 13 and 18 have slides 182 and 183 cooperating with bases of the triggers 7 and 8 to ensure the centering and the holding in position of these triggers 7 and 8. These means determine the positioning references of the triggers 7 and 8 with respect to to the housing.
  • a cover 93 covers the housing 1.
  • the drawers 3 have notches 36 which, when these drawers are recessed, are aligned with notches 181 of the partitions 131 or side partitions 13. Lugs 931 formed in the cover 93 engage in the notches to ensure keying immobilizing the drawers 3.
  • Drawer 2 can be keyed in the same way.
  • So-called “deionization” plates can be placed near the contacts to facilitate rapid interruption of the current. These plates can be mounted on the drawers or on the housing.
  • the thermal triggers 7 (or the electromagnetic triggers 8) could be mounted on the drawers 2, the drawers 3 carrying the other triggers 8 (or 7).
  • Drawers 2 and 3 and their associated components are mounted separately. The drawers 2 and 3 mounted are then embedded in the channels of the housing 1.
  • blowing loops are insulated between the walls of the drawer and the partitions of the housing.
  • each of the two drawers could be embedded in the housing in a direction making an angle with the bottom of said housing.
