Intelligent relay power supply device

The invention relates to an intelligent relay power supply device. The device comprises a master control module and a boost compensation control unit, the boost compensation control unit comprises an isolation transformer, an AC/DC module and a DC/AC module, a secondary side of the isolation transformer is used for series connection to a power transmission main loop, an AC input terminal of the AC/DC module is used for being connected to the power transmission main loop, a DC output terminal of the AC/DC module is used for being connected to a DC input terminal of the DC/AC module, an AC output terminal of the DC/AC module is used for being connected to a primary side of the isolation transformer, and the main control module is used for controlling the AC output voltage of the DC/AC module. According to the technical scheme of the device, the problem of low-voltage long-distance transmission is solved, the low voltage can be basically and stably maintained at the rated voltage in the long-distance transmissio
