Definitions

  • the present invention relates to a contactor-circuit breaker type switching device provided with at least one power pole constituted by fixed contacts cooperating with movable contacts linked to a control part actuated by an electromagnet or by a linked lock lever. to a lock.
  • the contactor-circuit breakers have power poles each consisting of a contact bridge cooperating with fixed contacts connected to connection terminals.
  • the action on the movable contacts can be done, in parallel, by an electromagnet (contactor function), by an electromagnetic trip device (short-circuit protection function), by a thermal protection module (overload protection function , phase imbalances and overcurrents).
  • the fixed contacts and the contact bridge of each pole are housed in an insulating cartridge forming the breaking chamber and ensuring isolation between the poles.
  • the object of the present invention is to provide a contactor-circuit breaker device in which the effects of inertia have been limited and in which the disassembly and replacement of the cartridges are facilitated.
  • the circuit breaker When the circuit breaker is open, there is no mechanical connection between the electromagnet and the poles.
  • the device is characterized in that the lock lever directly actuates the control part of the movable contacts and that the movable parts of the electromagnet actuate the control part by a link lever capable of be coupled to said movable parts by a removable coupling associated with blocking means subject to the state of the lock.
  • the blocking means consist of a guide and blocking part which guides or blocks the end of the lever in the removable coupling or its release.
  • the link lever and the lock lever actuate a control part linked in rotation to the movable contacts which are rotary.
  • each pole is housed in a cartridge disposed between the lock and the electromagnet.
  • the switch-type circuit breaker device which is illustrated in the drawings comprises several double-break power poles.
  • Each power pole comprises on the one hand a set of fixed contacts 1 and 2 which are connected to two connection pads 31 and 32 provided with terminals and on the other hand a bridge of movable contacts 5 cooperating with these fixed contacts 1 and 2 so as to establish or interrupt the flow of current between the terminals.
  • the terminals are used to connect external electrical conductors.
  • the contact bridge 5 is mounted on a bridge support made of insulating material.
  • the fixed contacts and the movable assembly equipped with the contact bridge of a pole are housed in an insulating cartridge 7 forming the breaking chamber and ensuring the isolation between poles.
  • the different cartridges 7 are arranged, side by side, between the electromagnet 8 and the lock 23.
  • Each cartridge 7 contains, in addition to the fixed contacts, the contact bridge and the associated bridge support, deionization fins.
  • the electromagnet 8 which operates the movable contacts consists of a fixed magnetic circuit 9, a magnetic circuit 10 movable in translation and a coil 11.
  • the coil 11 is provided with supply terminals which are accessible to the outside of the case.
  • a return spring acts on the mobile magnetic circuit 10.
  • the control part 15 of the contacts is connected by an articulation 16 to a connection lever 13 which is capable of being moved by the mobile magnetic circuit 10 of the electromagnet.
  • a connection lever 13 which is capable of being moved by the mobile magnetic circuit 10 of the electromagnet.
  • the end of the lever 13 has a hooking finger 19 which can engage in a hook 221 of the slide 22.
  • the removable end 19 of the lever 13 is associated with a blocking or guiding part 14 which can pivot around an axis 25 on the housing.
  • the latching finger 19 is guided in translation in a rectilinear slide 141 of the locking piece 14.
  • the contactor-circuit breaker has, at the front, a lock 23.
  • the control part 15 of the contacts is joined to the lock 23 by a lock lever 12.
  • This lever 12 is articulated, around an axis 20, to the parts movable parts of the lock 23 and is connected by a sliding and articulated assembly 121 to the control part 15 of the movable contacts.
  • a trigger module 4 is mounted on the device to provide the protection functions.
  • the bridge support is guided in rotation about a pivot axis 6.
  • the middle part of the contact bridge 5 is housed in a housing of the support so as to be able to pivot relative to this support.
  • the contact pressure is obtained by springs which tend to move the contact bridge 5 relative to the support.
  • the control part 15 of the contacts is a crank 15 linked to the bridge support and which therefore pivots about the axis 6. The movement of this crank takes place outside the cartridge.
  • the assembly between the lock lever 12 and the control part 15 is constituted by a control rod 17 which is integral with the crank 15 and which slides in a slot 121 of the lock lever 12. This assembly allows the movement of the rod 17 and of part 15 during operation in contactor.
  • the lock lever 12 has a notch 122 in which can be accommodated a lug 21 of the locking piece 14. When the lug 21 is positioned in the notch 122, the lock lever 12 blocks the locking piece 14. This this has a light 142 allowing the movement.
  • the control rod 17 passes through the various bridge supports and the cranks 15.
  • a second control rod 18 is provided.
  • the slide 22 has a fork shape, the two branches of which are introduced into the two spaces which each extend between two cartridges. In these two spaces are also housed the lock levers 12, the parts 15, the locking parts 14 and the connection levers 13.
  • the contacts are closed, the lock 23 is in the "On” position and the electromagnet 8 is energized.
  • This position corresponds to the "on" position of the contactor or circuit breaker.
  • the slide 22 of the electromagnet 8 is coupled to the connection lever 13 which maintains the control part 15 in the closed position of the contacts.
  • the contact pressure between the movable bridge contacts and the fixed contacts is generated by the pressure springs housed in the bridge support.
  • the excitation of the electromagnet coil determines the displacement of the movable magnetic circuit 10 backwards and therefore the movement of the link lever 13 and the displacement of the control part 15 of the contacts.
  • the contacts of the bridges 5 come to bear on the fixed contacts 1 and 2.
  • the springs internal to the bridge supports put the movable contacts under pressure against the fixed contacts.
  • the circuit breaker tripping orders pass through the lock 23 which acts mechanically on a contact.
  • the lock 23 can be actuated manually by the control lever 24 or by the trigger module 4.
  • the closed position which is illustrated in FIGS. 1 and 6, will be considered as the initial position.
  • the lock 23 When the lock 23 is released ( Figures 3 and 8), it pulls the lock lever 12 forwards. This lock lever 12 moves the part 15 and the mobile contacts. The lock lever 12 releases the blocking part 14 which can then pivot.
  • the rotation of the control crank 15 caused by the movement of the lock lever 12 drives the link lever 13 which rotates the locking piece 14 and releases the axis 19 of the notch 221.
  • the poles open. It is noted that there is no longer a positive connection between the electromagnet and the mobile bridges.
  • the removable assemblies between the link lever 13 and the slide 22 allow the dismantling and replacement of the removable assembly formed by the cartridges 7 and the lock 23.
  • the conductors mounted in the cartridges must first be separated from the conductors 31 and 32 which carry the terminals and remain mounted on the base. Furthermore, the pins 19 must be released from the slide 22 and for this the lock 23 must be put in the "off" position.
  • the contact supports and bridges instead of being mobile in rotation, are mobile in translation.
