Abstract
PURPOSE: For preventing the danger of power leak, to work a power supply breaker by triggering a breaker driving cyristor in accordance with the output of a leakage detector for detecting the zero phase component of the AC power supply current to a glow discharge heater.
CONSTITUTION: If any power leak occurs on glow discharge heater side 4, a difference takes place between the primary both-way current values of a zero-phase current transformer 17 and an output is generated to a secondary coil winding to work a breaker 19 by triggering a cyristor 20 through an amplifier 18 so that contacts 191 and 192 are opened. Further, if the temperature in the tank of said glow discharge heater 4 has risen abnormally due to the failure of a heat sensing element 12 and a control circuit 9, the heat sensing cyristor 13 detecting this makes continuity to trigger a breaker driving cyristor 20 through a pulse transformer 26 and to break said breaker 19.
