Abstract
A surge protection system includes a receptacle body, at least one power output jack, a power obtaining device, at least one surge protection module, a microcontroller unit, and a surge detection circuit. The at least one surge protection module includes a housing, a memory element, and a surge protection circuit that includes a surge absorption element and a thermal fuse connected in series and parallel. The surge absorption element absorbs a surge inputted from an external power supply, and the memory element records a number of surges carried by the surge absorption element. When the surge enters the surge protection system from the external power supply, the surge absorption element absorbs the surge, and the surge detection circuit outputs a signal to the microcontroller unit that writes the number of surges carried by the surge absorption element into the memory element.
