Self-inspection module of electronic circuit breaker

The invention discloses a self-inspection module of an electronic circuit breaker. The self-inspection module of the electronic circuit breaker comprises a power module, a self-inspection starting module, an induced power supply module, a boosting power supply module and a micro-control unit, wherein the power module comprises a rechargeable battery; the self-inspection starting module comprises a starting button, a capacitor and a first power chip which are serially connected to one another; the self-inspection starting module is connected to the rechargeable battery; the induced power supply module comprises a voltage reduction chip; the boosting power supply module comprises a second power chip and a boosting chip which are serially connected to each other; the micro-control unit is provided with a plurality of pins; and the pins are respectively connected to the first power chip, the second power chip, the voltage reduction chip and the boosting chip. The self-inspection module of the electronic circuit breaker has two working modes; when in the first working mode, the self-inspection module does not have load current; and when in the second working mode, the self-inspection module is connected to the load current. A self-inspection program runs on the micro-control unit, and a self-inspection state is indicated and is maintained for a period of time.
