Abstract

PURPOSE:To stop the supply of electricity upon only an abnormal operation due to an abnormal current and prevent the burning of a circuit, by a method wherein a normal power supplying means, interrupted upon detecting the abnormal operation, and an abnormal power supplying means, operated upon detecting the abnormal operation and interrupted by an overcurrent, are provided in the circuit. CONSTITUTION:A normal power supplying electric path 6 and an abnormal power supplying electric path 5 are provided in parallel to a power supplying path from a power source 1 to a load 4. The normal power supplying electric path 6 supplies electricity when the operation of a circuit is normal and is interrupted when the abnormal operation of the circuit is detected by a detecting means 5. The abnormal power supplying path 5 supplies an electricity when the abnormal operation of the circuit is detected and is interrupted by detecting an overcurrent by an element 51 when the overcurrent is conducted. According to this method, minimum power supply may be continued even upon abnormal operation and, further, the burning due to overcurrent may be prevented in this case.
