Cable load current CT electricity-taking intelligent power supply device

The utility model relates to the technical field of intelligent power supplies, specifically to a cable load current CT electricity-taking intelligent power supply device. An output end of electricity taking CT is connected with an input end of a rectifying device through a power input interface, an electricity taking CT wakeup current, i.e., a primary current or cable load current is required to be 10A, and output voltage of the rectifying device is 16V in a load current range of 20 to 500A; an input end of a system mainboard is connected with an output end of the rectifying device, the other end is connected with a battery matched with a bypass, and an output end of the system mainboard is connected with a power output interface and is connected to a load through a power line; and the cable load current CT electricity-taking intelligent power supply device can supply power to monitoring equipment under circumstances of no power supply or sudden power failures.
