5. Working Principle
GE C60-U01-HCH-F8F-H6P-M8F-P6P-U6P-WXX circuit breaker protection device adopts a full closed-loop working mechanism: electrical quantity acquisition → signal conditioning and calculation → condition monitoring and discrimination → protection logic comparison → fault action output → data storage and upload → intelligent self-diagnosis, realizing all-round intelligent management and control of circuit breakers and power distribution lines.
During normal equipment operation, the device collects three-phase voltage, current, frequency and other electrical parameters of the power distribution system in real time through high-precision sampling loops. Meanwhile, mechanical condition information such as circuit breaker switching status, energy storage status and operating circuit status is collected via digital interfaces. The built-in computing unit performs filtering and noise reduction, calculation calibration and logic analysis on the collected data to evaluate system load conditions and circuit breaker operating status in real time. Under normal working conditions, it continuously uploads operating data and retains working condition records to ensure stable system monitoring.
When short circuit, overload, earth fault, abnormal voltage and other faults occur in distribution lines or circuit breakers, the device quickly completes fault discrimination and threshold comparison, accurately triggers corresponding protection logic, instantaneously outputs tripping and alarm signals, rapidly isolates the faulty circuit to avoid fault expansion. Meanwhile, fault waveform recording is automatically activated to completely record fault waveforms, action events and switch state change information and retain data for fault tracing. The device conducts real-time self-inspection on hardware status, sampling loops, communication links and operating circuits throughout the whole process. Once anomalies are detected, alarm information is uploaded and fault codes are recorded immediately to realize early fault warning and active protection, comprehensively ensuring safe and stable operation of power distribution systems and circuit breaker equipment.
