Abstract

PURPOSE: To interrupt main circuit current reliably upon occurrence of fault by monitoring the operation of a high speed circuit breaker through a fault detecting means and opening the main circuit through an opening means upon detection of fault.
CONSTITUTION: Main circuit current is detected through a current sensor 6 and fed to an overcurrent detecting section 7. Gate signal to a thyristor 9 is fed from a gate control section 8. Fault detecting section 10 is provided with state monitoring signals from the overcurrent detecting section 7 and the gate control section 8, and an output relay is operated when an abnormality is detected in a high speed circuit breaker 4. The output relay is of a normally excited type and an output can be produced from the abnormal side even if control current is cut off. The output relay 11 provides an indication to an operator and opens a main circuit switch connected in series with the high speed circuit breaker 4.
