Definitions

  • the invention lies in the field of the safety of electrical installations, and in particular of the interruption of the electrical power supply, commonly called a disconnection, in the event of the presence of an electrical fault in an installation.
  • auxiliary protection modules with electronic microcontroller are also known, adapted to be connected to existing magneto-thermal circuit breakers. Such auxiliary electronic protection modules are configured to implement protection, for example, in the event of the appearance of electric arcs liable to occur in defective conductors or connections. In addition, auxiliary modules are configured to implement differential protection, and the electronic microcontroller is adapted to perform such a differential protection function, causing the power supply to be cut off.
  • the circuit is supplied with a known reference voltage, at a supply point electrically connected to a connection point associated with the second handle.
  • the modules 2, 4 are integrated in a one-piece housing which forms the housing of the disconnection device, with no electrical connection of position information other than the current flow line supplying the loads downstream of the disconnection module.
  • the second handle 18 of the auxiliary protection module 4 is mechanically linked or polarized to the first handle 16 of the circuit breaker module 2.
  • Another embodiment consists in mechanically connecting the two handles 16 and 18, the opening and closing of the handle 16 causing the handle 18 in the same positions.
  • the mechanical link is in this case made by any suitable bidirectional mechanical link.
  • the voltage read on the third input 45C of the processing unit 42 is equal to 0V if the switch 56 is open or if there is a loss of electrical supply inducing a loss of reference voltage.
  • the average current value on the sliding window is calculated and compared with the threshold current value In at step 62.
  • a sudden jump is characterized for example in that the maximum value (or peak value) of a half-cycle, called the current peak value, is greater than the average value of the peak values per half-cycle over a number of half-cycles previous ones. For example, it is checked whether the current peak value is greater than twice the average value of the peak values per half-cycle over 8 previous half-cycles.
  • the auxiliary electronic protection module is configured to detect the movement of the lever of the trip mechanism of the associated magneto-thermal trip module, and to determine the cause of the trip as a function of voltage and current measurements. .
