Definitions

  • the temperature difference between the ambient temperature of the wire and the temperature of the wire is calculated over time based on the current information indicating the current value flowing through the wire, and the calculated temperature Add the difference to the ambient temperature.
  • the wire temperature is calculated.
  • the calculated wire temperature is equal to or higher than the threshold temperature, for example, the current flowing through the wire is cut off by turning off a switch provided in the middle of the wire.
  • Analog current information from the current detection unit 32 is input to the input unit 44.
  • the input unit 44 outputs the input current information to the A / D conversion unit 48.
  • the timer 49 periodically outputs to the A / D converter 48 a conversion instruction that instructs to convert analog current information into digital current information.
  • the determination unit 47 determines whether or not the current value indicated by the current information input from the A / D conversion unit 48 is greater than or equal to the reference current value. Specifically, the determination unit 47 determines whether or not the digital current information, that is, the digital voltage value is greater than or equal to a reference value.
  • the reference value is a digital voltage value output by the A / D converter 48 when the current of the reference current value flows through the electric wire 20. Further, the reference current value is sufficiently smaller than the aforementioned breaking current value.
  • Rth is the wire thermal resistance (° C./W) of the wire 20
  • Rw is the wire resistance ( ⁇ ) of the wire 20
  • To is a predetermined temperature (° C.)
  • Ro is a wire resistance ( ⁇ ) at the temperature To.
  • ⁇ is the wire resistance temperature coefficient (/ ° C.) of the wire 20.
  • ⁇ Tw, ⁇ Tp, Iw, and Ta are variables, and ⁇ t, ⁇ , Rth, Ro, ⁇ , and To are preset constants.
