Abstract
PURPOSE: To protect the thyristor amplifier, by means of inhibiting an output of the phase shifter at an operational time of the overcurrnt fault detecting relay.
CONSTITUTION: A firing pulse, fed from an output winding 7, 8 of the magnetic phase shifter, makes a firing control for a thyristor 2, 3, to control the power fed to a load 4. At this time, in the primary side of a transformer 1 that feeds an AC power source to the thyristor amplifier, is provided an overcurrent relay 18 through a current transformer 16. In case of the overcurrent relay 18 happening to work due to a short-circuit of the thyristors 2, 3, a contact 18b2 of said overcurrent relay 18 disconnects a power supply to the magnetic phase shifter, to inhibit a firing pulse fed to the thyristor 2, 3 from the magnetic phase shifter, and protecting the thyristor amplifier.
