Definitions

  • the present invention relates to the improvement of an electrical circuit breaker module of known type, incorporating a conventional circuit breaker.
  • the improvement consists in inserting into the module a controlled switch for triggering or engaging the bypass circuit associated with the module.
  • This controlled switch is housed in the module without having to make any modification whatsoever to its thickness (height of the front wall), along the vertical plane, as well as to its depth.
  • the utility value of an electric circuit breaker module inside a connection box is obvious and this value is increased when the module includes an additional controlled switch used to engage or trigger the electrical bypass circuit with which it is associated.
  • the activation of the controlled switch can be controlled remotely from the connection box so as to activate it when necessary or using programmable or non-programmable control automations. This then results in a control of each electrical branch circuit of a connection box or of those which it is thus desired to control so as to control the supply of the electrical charges connected to each of the circuits.
  • Another important advantage inherent in this improved circuit breaker module is that the user has the ability to automatically control a variety of electrical branch circuits.
  • timer devices or other programmable devices it is possible to control the switching on or off of lighting or other electrical devices at predetermined times of the day when the premises are unoccupied or during periods vacation. Such an operation of electrical devices would then simulate an occupation of the premises.
  • Another advantage of this type of electrical circuit breaker module lies in the ability to manage the distribution of loads, which leads to energy conservation with regard in particular: the electric heating systems which can be programmed for n '' be operated only at predetermined times and / or in response to changes in temperature.
  • Another characteristic resides in a controlled switch element which is small enough to be incorporated into a circuit breaker module and which requires a relatively low power supply for its operation with a view to switching on and off electrical branch circuits of 110 or 220 volts or other similar low voltage branch circuits below 600 volts.
  • a characteristic of the present invention resides in the production of an improved electrical circuit breaker module which meets the needs stated above and which is substantially free from all the disadvantages of the device of the prior art mentioned above.
  • Another characteristic of the present invention consists of an electric circuit breaker module which incorporates a conventional circuit breaker and a switch device controlled inside the same module without modifying the thickness of the module, along a vertical plane.
  • Another characteristic of the present invention is to provide an improved circuit breaker module which has a controlled switch device, the control of which is carried out from a place remote from a connection box and / or automatically by the user or a scheduling device.
  • Another characteristic of the present invention resides in an improved electrical circuit breaker module which has a conventional circuit breaker and a switching device: controlled and which can adapt to an existing connection box which incorporates a plurality of conventional electrical circuit breaker modules without it it is necessary to - move the already wired existing modules.
  • Another characteristic of the present invention resides in the production of an improved electric circuit breaker module comprising a conventional circuit breaker and a controlled switch device and which is relatively inexpensive to manufacture and install.
  • the present invention relates to an improvement of an electrical circuit breaker module, plug-in, of small size, and which is mounted superimposed in columns by stacking on a plurality of modules at the inside of an electrical connection box.
  • Each of the modules is respectively connected to electrical branch circuits and is provided with circuit interruption means for disconnecting the branch circuit with which it is associated at the time of an overcurrent or a fault on the branch circuit.
  • the improvement includes a controlled switch means mounted in at least one of the modules, without modifying the thickness of the module, according to a vertical plane, and its depth. This controlled switch means is connected in series by means of a circuit switch and is put into operation using an external or internal control means of the module which governs the open or closed state of the contacts.
  • the electrical circuit breaker module of the present invention is generally designated by the reference 10.
  • the module consists of a conventional enclosure formed of an insulating material and houses a switch mechanical 16 coupled to an overcurrent protection element 12 (see Figure 4).
  • circuit breaker modules 10 are usually fixed to a connection box by stacking one on the other.
  • Each module may include one or more marking connections 13 and one or more electrical connections 14 so as to connect a module to a particular electrical branch circuit among the plurality of circuits entering and leaving the connection box, as is well known in art.
  • the modules can also be of the type which can incorporate fusible elements of the screw or cartridge type. tubular which can be fixed in a removable way on the front of the module.
  • These modules are of different construction from those illustrated in Figures 1 and 2 but are similarly stacked on top of each other and / or side by side.
  • the present invention relates to an improvement of such a circuit breaker module in which a controlled switch element 15 is inserted inside this same module 10 without having to modify the thickness of the module taken along the vertical plane. As illustrated in Figure 4, this switch element 1.5 is connected in series with the circuit breaker element 12. As shown in Figure 2, the circuit breaker module is provided with a manual control button 16 allowing the circuit breaker to occupy the position "ON” or "OFF".
  • the controlled switch device 15 it is operated remotely, relative to the connection box and can be activated using an electrical signal, in this case a low power source connected to socket 18 enabling the switch element 15 to be activated or deactivated.
  • the command may be produced by the user himself and / or the operating company which owns the energy transport network. It is also conceivable the possibility of controlling the switch element 15 according to an established schedule so as to engage and trip the electrical circuit coupled to the circuit breaker module 10 at hours and according to predetermined conditions during the day so as to control various electrical devices connected to the branch circuits.
  • the switch element 15 may consist of an electronic switch or other means. All that is actually required is that the switch is of relatively small size and is capable of operating at very low power and that it is further able to engage and trip branch circuits operating at voltages of 110 or 220 Volts for example, which correspond to the voltages usually used at the residential and commercial level.
  • the switching element 15 consists of a thermo-mechanical switch comprising an actuating element formed of a bi-metallic disc 19, sensitive to temperature, on which is fixed a heating conductive element 20 capable of causing deformation of the disc when it is heated.
  • the disc is of concave / convex construction and formed of a bi-metallic material so that the heating of the disc causes it to expand and move from its normal position to another position designated by 19 'in Figure 5.
  • the disc 19 is held by means of a rigid side wall 26 which allows the deflection of the disc in the position 19 '.
  • a rigid rod 17 connects the lower surface 21 of the disc 19 to the arm 22 of the switch so that when the disc is heated and occupies the position shown in 19 ', the contact 22 is open (as shown by the dotted lines) opening thus the associated branch circuit 23 connected to the circuit breaker module housing the switch element 15.
  • 1e disc 19 has a circular configuration while the filiform heating element 20 is arranged in a serpentine over a large part of the surface of the disc 19.
  • the disc 19 can also be formed from a bi-band. rectangular metal.
  • the switch is actuated by applying a voltage across terminals A and B of the threadlike heating element.
  • the enclosure 24 of the switch is connected in series to line 23 of the branch circuit using the end conductors 25.
  • thermo-mechanical disc switch lies in the very low power required for actuation.
  • the construction of the disc allows rapid action to interrupt the supply of the electric circuit 23 which can be subjected to a current of 30 amps, for example.
  • this switch allows it to be incorporated inside the module housing the conventional circuit breaker and to achieve the various advantages described above.
