Abstract

PURPOSE: To produce the 4 parameter restriking voltage waveform surely stable, by connecting the second voltage source capacitor in parallel connection with the second voltage source reactor of the voltage source circuit via a gap to the second voltage source reactor parallelly without timing dispersion.
CONSTITUTION: The capacitors 14 and 16 are of opposite polarity each other and charged up with equal voltage, and as the series circuit of the capacitors 14 and 16, the initial voltage is zero. At the gas 15a, the voltage of the first voltage source capacitor 8 is split with the first and second reactors 10 and 11 and fed at the moment when the first control gap 9 is discharged, and the charge voltage of the capacitor 14 is made independently of the voltage between the poles of the gap 15a. Thus, the voltage between the poles of the gap 15a when the gap 9 is discharged is reduced. Further, since the voltage between poles is increased when the circuit close is requested, the gap 15a can be discharged surely without timing dispersion.
