THE DETECTION DEVICE MOUNTED TO CIRCUIT BREAKER AND THE DETECTION SYSTEM OF THE AUXILIARY POWER OUTLET INFORMATION USING IT

摘要

PURPOSE: A detection device for circuit breaker combination and a main line abnormality information detection system are provided to remotely monitor abnormality information in an integrated monitoring control panel and open a contact point of a molded case circuit breaker by generating a trip signal in an abnormality state, thereby intercepting power and maintaining safety. CONSTITUTION: A metering module(220) is mounted in a molded case circuit breaker. The metering module comprises a current transformer(CT), a zero-phase current transformer(ZCT) and an output unit. A signal processing module(240) is mounted in the metering module and receives line state information and outputs the received information with digital or analog conversion processing.
