Smart power gateway power management device

The invention relates to a power management device for a smart power gateway, in particular to a monitoring technology capable of effectively saving power, safety management of electricity and automatic detection of lines.

Press, general buildings (such as homes, companies, schools, dormitories, and factories) have at least one set of AC power circuits to transmit external AC power to the power outlets to supply the electrical power needed for electrical products. . Generally, one end of the above-mentioned AC power supply circuit is electrically connected to a mains (AC). Each group of AC power supply circuits is electrically connected in sequence by a wire group, including a fuse line switch (NFB) and a power socket. The no-fuse switch (NFB) is located in the electrical box. When the AC power supply circuit is over-current or overloaded, the no-fuse switch (NFB) disconnects the mains (AC) from the abnormal AC power supply circuit. The safety monitoring function; however, the conventional structure does not have the function of accumulating the power data and the power safety warning, so that the user cannot know the status information such as the immediate power supply and power consumption of the AC power supply circuit, so that the power cannot be effectively generated.
