摘要： With a wire protection method in accordance with the present invention, the method being used for supplying electric power from a power source to a load, an applied-current to the load is detected every predetermined time, A wire rise temperature is calculated using the detected applied-current I(n) and by a relational expression concerning heat radiation and heat generation of the wire. The calculated rise in temperature is added to a reference temperature so that a wire temperature is estimated. When the estimated wire temperature is lower than a predetermined upper limit temperature, the calculation of the rise in temperature is repeated. When the estimated wire temperature has become equal to or higher than the predetermined upper limit temperature, the electric power supply from the power source to the load is stopped so that the wire is protected.

Supposing that the temperature increasing amount of a semiconductor element caused when the semiconductor element is turned on is ΔTch, the on-resistance value of the semiconductor element (T1) is Ron, the thermal resistance value of the semiconductor element (T1) is Rth_f, the temperature increasing amount of a connecting wiring is ΔTw when a current flows into the connecting wiring (WL), the resistance value per unit length of the connecting wiring is Rw, and the thermal resistance value per unit length of the connecting wiring is Rth_w, ΔTch is obtained based on an expression of ΔTW/ΔTch=Rth_w/Rth_f*Rw/Ron with respect to the temperature increasing amount ΔTw not exceeding a difference between the upper limit of the permissible temperature of the connecting wiring (WL) and the upper limit of an operational peripheral temperature, then a voltage Vds is obtained based on an expression of ΔTch=Rth_f*Vds2/Ron with respect to the ΔTch thus obtained, and the voltage Vds thus obtained is set as a determination voltage.

摘要： A fireguard circuit for a power cable, which comprises a power line, a neutral line and a metal sheath surrounding the power line and the neutral line, includes a switch located in one of the lines. A solenoid sets the switch in either an open position or a closed position. A first silicon controlled rectifier (SCR) causes the solenoid to open the switch upon detecting the presence of an arcing condition between the power line and the metal sheath. A second silicon controlled rectifier (SCR) causes the solenoid to open the switch upon detecting the presence of an arcing condition between the neutral line and the metal sheath. The second SCR is connected in parallel with the first SCR, the anode of the first SCR being connected to the cathode of the second SCR and the cathode of the first SCR being connected to the anode of the second SCR.
