摘要: An arc fault circuit interrupter (AFCI) device prevents malfunction of an electric circuit and checks the state of the circuit and connection state of lines. One of a phase conductor line and a neutral conductor line is wound around a transformer which converts a current difference flowing in the AC line into voltage to detect whether an arc fault occurs, and a voltage induced by the wound line is rectified into direct-current and is converted into constant voltage to obtain power for the AFCI. An arc wave generator includes a rectifier to generate a rectified signal; a drop resistor which drops the voltage of the rectified signal to generate a voltage-dropped signal; and a mono-stable multivibrator which adjusts a voltage level and a pulse width of the voltage-dropped signal and generates a pulse signal that is used to generate a false arc for testing the AFCI.

摘要: A composite electric circuit breaker, and method thereof, is configured to detect signals regarding arc faults, overcurrent, and earth leakage. Arcs and electric currents are detected by a current transformer and earth leakage is detected by a zero phase current transformer. A variation of electric current, the number of arcs which are generated per a unit time, a present electric current value, and electric current earth leakage are combined to judge whether arc faults occur to then interrupt an electric power supply. Temperature is measured on a printed circuit board, and if temperature rise occurs, the electric power supply is interrupted, and an interruption cause is displayed. Electric accidents and occurrence of fires are prevented simultaneously and more accurately. The interruption causes can be confirmed, analyzed and externally monitored through a network, to thus maximize efficiency of electric management.
