摘要： PURPOSE:To eliminate monitor performed by a maintainer and at the same time to give the close monitor to the stability of electric descharge, by counting the shifting frequency from the glow discharge to the arc discharge to obtain a detection output. CONSTITUTION:The pulse number setting mechanism of a pulse counter 7 is set to the proper number of pulses that decides no recovery to the normal glow discharge. When the glow discharge of load becomes unstable, the output DC voltage corresponding to the arc discharge stage is devided by a potentiometer 3 to be applied to an input terminal of a comparator 4. This divided voltage is then compared with the voltage of a setting power supply 5. As the voltage of the supply 5 is set at the divided voltage at that moment, the signal is delivered from the comparator 4 at this moment. Then the pulse is generated from a pulse generating circuit 6. The counter 7 counts these pulses and delivers a ddtection signal when the count value reaches the set pulse numerical value. This detection signal actuates an alarm curcuit 8 and a breaker 9. Thus a power supply circuit is cut off, and at the same time an alarm is produced.
