The invention discloses a three-phase load imbalance automatic on-load adjustment method and an operation and control method of a distribution network. The device comprises a three-phase phase voltageacquisition transformer, a three-phase output control switch, an automatic control circuit and a rectification power supply. The three-phase phase voltage acquisition transformer is used for acquiring three-phase phase voltage of the position where the device is located, and transmitting the three-phase phase voltage to the automatic control circuit in a manner of a communication protocol or other electric quantity conversion through conversion. The three-phase output control switch is used for operating and controlling the load to be connected to the A phase, the B phase or the C phase. A remote control emission device is used for connecting user load to a certain phase or directly cutting off the load. The rectification power supply is used for converting the three-phase high-voltage alternating current into th
