Description:
- The power supply (PS) provides power to the circuit.
- The microcontroller (MCU) is the brain of the system and controls the circuit breaker (CB) and other components.
- The control panel (CP) is used to interact with the system and monitor its status.
- The circuit breaker (CB) is a safety device that interrupts the power supply when a fault is detected.
- The relays (R1, R2) are used to switch the power supply to the circuit breaker and other components.
- The LEDs (L1, L2) indicate the status of the system (e.g., power on, fault detected).
- The push buttons (PB1, PB2) are used to interact with the system (e.g., reset, test).
- The fuses (F1, F2) protect the system from overcurrents.
Operation:
- When the system is powered on, the microcontroller (MCU) initializes and checks the status of the circuit breaker (CB).
- If the circuit breaker (CB) is in the "off" position, the microcontroller (MCU) sets the relays (R1, R2) to disconnect the power supply to the circuit.
- If the circuit breaker (CB) is in the "on" position, the microcontroller (MCU) sets the relays (R1, R2) to connect the power supply to the circuit.
- When a fault is detected, the microcontroller (MCU) sets the circuit breaker (CB) to the "off" position and sets the LEDs (L1, L2) to indicate a fault.
- The user can reset the system by pressing the push button (PB1) and the microcontroller (MCU) will reset the circuit breaker (CB) to the "on" position.
- The user can test the system by pressing the push button (PB2) and the microcontroller (MCU) will simulate a fault and set the circuit breaker (CB) to the "off" position.
Notes:
- This is a basic schematic and may not include all the components or features required for a real-world circuit breaker control system.
- The microcontroller (MCU) and relays (R1, R2) may require additional components such as resistors, capacitors, and diodes to function properly.
- The circuit breaker (CB) may require additional components such as thermal sensors and timers to detect faults and reset the system.
- The system may require additional features such as alarm outputs, communication interfaces, and user interfaces to interact with the system.
