The invention relates to an integrated circuit and discloses a chip power-on reset circuit and method thereof. In the invention, the chip power-on reset circuit comprises a pre-charge module, a charge charging and discharging module, a wave shaping module and a forced response module, wherein the pre-charge module is used for controlling the charging current of the charge charging and dischargingmodule; the charge charging and discharging circuit transforms the charging current into charging voltage and outputs the charging voltage; the wave shaping module amplifies and shapes the charging voltage to generate a POR (Power-On-Reset) signal; and the forced response module monitors the POR signal in the whole process and generates an output signal to lock and control the pre-charge module. Because the chip power-on reset circuit can generate the POR signal under the condition that the power voltage raises very slowly, after the power voltage is stable, the own power consumption is equalto zero.

An electromagnetic operating mechanism used in a circuit breaker for smart meters, including an electromagnetic mechanism and an energy-saving mechanism. The electromagnetic mechanism includes an electromagnet, a reaction force spring, and a transmission mechanism; The moving iron core of the iron moves to its suction position when the coil is energized, and the locking unit forms a locking structure with the moving iron core to keep the moving iron core at the suction position. At the same time, the energy-saving unit Immediately after the moving iron core leaves the initial position, the control coil is powered off, thereby realizing zero power consumption when the electromagnetic mechanism is working, and saving a lot of electric energy; the tripping unit can receive the tripping command to trigger the locking unit to unlock the locking structure, so that the The moving iron core quickly returns to its original position, and the trip unit can return to its return position after tripping for the next use.

Provided is a zero-power-consumption intelligent standby power saver. The zero-power-consumption intelligent standby power saver comprises an EMI filter circuit MD1, a current detection and energy storage circuit MD2, an MCU control circuit MD3, a magnetism maintaining and driving switching circuit MD4 in a sequential connection mode, wherein the EMI filter circuit MD1 is used for inputting common-mode rejection alternating-current interference signals and preventing alternating-current interference signals which are generated inside from being outwards transmitted, the purpose of environmental friendliness and the purpose of being free of pollution are achieved, the current detection and energy storage circuit MD2 is used for detecting current of an electrical appliance and storing electric energy, the MCU control circuit MD3 is used for giving out control instructions to the magnetism maintaining and driving switching circuit MD4, and the magnetism maintaining and driving switching circuit MD4 receives the control instructions from the MCU control circuit MD3 to start or stop the electrical appliance. According to the zero-power-consumption intelligent standby power saver, the purpose that the electrical appliance can automatically turn off an input power source of the electrical appliance when in a standby state is achieved, the electrical appliance can automatically turn off power supply input, and can be started through infrared wireless control, the effect of zero power consumption is achieved when the electrical appliance is in the standby state, and the electric energy is greatly saved.
