Title: Ac electromagnetic device
Inventor: KAKIZOE MASAHIRO
IPC: H01F7/18
Filed: 1983-07-20
Abstract: PURPOSE:To enable omittance of resistor for limiting discharge current of a capacitor for absorbing arc, by discharging the electric charge charged in the capacitor before a switch is opened. CONSTITUTION:The electric charge which has been stored in a capacitor C in the period from open circuit of an electric source 7 to closed circuit of a switch 12 is discharged through the inside closed circuit. In other words, when the switch 8 of the power supply 7 is opened to eliminate electric source, the electric charge in the capacitor C is discharged through the circuit i5. Since the period of time from dissociation of the core to closed circuit of the switch 12 is much longer that that needed for electric discharge of the capacitor C, the charge in the capacitor can be throughly discharged. Thus, no resistance is needed for limiting the discharge current of the capacitor.
