[0024] The function of the power comprehensive protection device is to monitor and control the on-off of the power supply line. Existing electrical appliances with high requirements for power supply stability often need to be equipped with a backup power supply. When the main power supply circuit can no longer supply power, it is necessary to switch to the backup power supply circuit to supply power to it. In order to ensure the timeliness of the switching, it is generally necessary to set a double-cut switch on the power supply circuit. Both the main power supply circuit and the backup power supply circuit are connected to the electrical appliances through the double-cut switch. When the main power supply circuit can no longer supply power, the double-cut switch automatically switches the backup power supply circuit to power the electrical appliances.
