Definitions

  • the present invention of improvements made to the mechanisms of differential circuit breakers to allow 'their coupling in or to automatic circuit breakers.
  • the active element in which the disconnection triggering begins that is to say the relay
  • this differential circuit breaker mechanism in addition to its tripping and resetting device which has the characteristics set out above with regard to precision and low inertia, there is also present the corresponding circuit test button which allows to check, at any time, the proper functioning of the device. According to the invention, this test button does not complicate the whole mechanism at all because of its design, the return spring of this button is used as a conductive element which establishes the closing of the test circuit.
  • the device according to the invention has, by its new design, a plurality of advantageous characteristics among which we can cite the fact that it comprises a single intermediate piece of plastic material, a floating adjustable trigger relay, simple mounting and adjustment, a test button for highly sensitive operation and absolute reliability.
  • the apparatus comprises, as can be seen in FIG. 1, an electromechanical assembly housed in a carcass 1 made of a dielectric material and which is separated into two separate compartments, namely a compartment for housing a transformer 2 and another compartment in which is located the actual differential mechanism which is triggered by the action of a relay 3 whose central rod is movable.
  • the differential mechanism warns of its triggering by the output to the outside of a push button 4 which also constitutes the element used for resetting it.
  • This push-button 4 carries, inside, a projection 5 on which a spring 6 bears against which the reset is carried out, this spring being the element which causes the push-button to exit in the case of '' an anomaly in the circuit.
  • the lower internal part of the push button 4 has a recess in which a pawl 7 can be hooked held in this position by a spring B, a position which ensures the retention of the push button 4.
  • a pendulum 9 articulated in its central part comprising two branches practically square, which constitutes a part with several cooperating functions, on one side , with the pawl 7 and also, on the other side, with an intermediate piece 15 as well as with a spring 13.
  • This pendulum 9 maintains its equilibrium position against a spring wound on its axis of rotation, by following the retention carried out by a bent lever of a piece 10, of plastic material, which constitutes the single element existing between the relay 3 and the rest of the differential mechanism.
  • the position of this lever 10 is also determined by the action of a spring 11.
  • the intermediate part 15 (FIG. 3) constitutes, between the carcass 1 and the rest of the housing which contains the disconnection contacts, a floating part, having the possibility of a sliding movement, the axis of rotation being indicated by the reference 18 in FIG. 3.
  • This part 15 is actuated, on one side on which it has a protuberance or a stud, by the pendulum 9 and it receives, on the other side, a rod 16 which constitutes the disconnection element poles of automatic circuit breakers.
  • the absolute protection of this sliding intermediate piece 15 ensures perfect transmission following any requirement or external action.
  • relay 3 its mounting is, as can be seen in FIG. 1, of the floating type and it is held by an adjustment screw 14 engaged in a lower appendage 17 which projects from the frame of the relay 3.
  • This screw 14 makes it possible to approach the relay 3 more or less of the lever 10.
  • the screw 14 carries a coaxial helical spring which brakes it and fixes the chosen position.
  • the pendulum 9 returns to its position shown in FIG. 1 when the reset push-button 4 is pressed, all the time after having resolved the cause which produced the trip.
  • the push button 4 rotates the balance 9 in the opposite direction which is then immobilized in a fixed position if the position of the bent lever 10 allows it.
