Definitions

  • the present invention relates to a low-voltage, single-pole double-break electric circuit breaker, the function of which is to protect the circuits against current overloads exceeding a predetermined quantity, equipped with a thermal compensation device.
  • its connection provided by plugging in on a connector makes it possible to constitute a group of n elements in "square base mosaic" to constitute particularly aesthetic paintings (interface in the form of a plan); the triggering of a unit causing its button to project from the interface plane is therefore immediately detectable.
  • a particular mode of installation of these circuit breakers makes possible unit disassembly from the front (button side), which has a double advantage: fixed wiring of receptacle connectors, integral with the structure, and maintenance facilitated by the possibility of removing an element from a live network.
  • Another advantageous technical feature of the invention resides in the independence of the interlocking-tripping mechanism with respect to the overload protection mechanism which cannot be mechanically hindered.
  • the present invention eliminates the aforementioned drawbacks by its design providing a single push button on which successive pressures will alternately cause engagement and tripping.
  • Figure 1a is a block diagram where the main elements are shown: 1 shows the push button having a blade whose end constitutes the stop 1a; 2 shows a projecting part secured to the housing in which the groove 2a has been arranged to allow the ball 4d to effect lateral movement; 4 constitutes the control shaft of the support 10, of the movable contacts 11.
  • the fixed contacts being shown diagrammatically by 12.
  • the axes X and Y respectively delimit the level of the surface of the push button when the circuit breaker is tripped or tripped.
  • FIG. 2 The mechanism for manual engagement and tripping of the contacts is shown in FIG. 2 and a section thereof according to III shown in FIG. 3 where the ball 4d is shown shown trapped between a profile 4a (bearing cage) of the shaft 4 and a groove 2a of the molded body of the device.
  • the ball 4d is shown trapped between a profile 4a (bearing cage) of the shaft 4 and a groove 2a of the molded body of the device.
  • the device for tripping following a fault will be described with reference to FIG. 1a where the device is shown switched on.
  • a current passing through the bimetallic strip 8 exceeds a predetermined value, the latter deforms by heating and allows the ball 6 under the pressure of the spring 5 to escape the stress exerted by the conical part 4b of the control shaft of the contacts 4 and slide along the cylindrical part 4c of this shaft.
  • the support assembly of the movable contacts 10 will go back up, stopped in its course by a burée 9.
  • This ball device constitutes the locking mechanism of the protection against overcurrents.
  • the device will be reset in two stages.
  • a first press on the push button will put the mechanism (after deleting it) in the conditions of the device triggered manually ( Figure le).
  • the ball will resume its position of support on the conical part 4b of the shaft 4.
  • a second pressure will reset the device according to the manual engagement process.
  • An ambient temperature compensation device is ensured by the action of a second opposing bimetallic strip in the locking mechanism, the embodiment of which is illustrated in FIG. 6 which is a section through the control shaft of the movable contacts 4.
  • Two half-rings 23 and 24 are mutually guided held around the axis of the 'shaft mentioned by traction springs 22.
  • half-rings are housed the ends of the bimetallic strips 20 respectively of overcurrent and compensator 21 whose efforts counteract the force of the springs.
  • the half-ring 23 applies the ball 6 to the cylindrical part of the shaft 4 at the level of the conical shoulder with a force F.
  • the force.F which keeps the movable contacts engaged is a component of three forces, including the antagonistic force of the temperature compensation bimetallic strip 21, which will act accordingly on the trigger point.
  • Figures 4 and 5 are sectional views of an embodiment of the apparatus according to the invention where the main operating elements are shown, in particular the push button 1, the fixed and movable contacts 11 and 12, the spring of the locking mechanism of the moving contacts 5 and the control shaft of the locking device 4 of the moving contacts.
