The utility model discloses a three-phase current imbalance adjustment and electric energy acquisition system. The system comprises a transformer, a main control device, a plurality of household commutation acquisition terminals and a monitoring terminal, the plurality of household commutation acquisition terminals and the monitoring terminal are respectively in optical fiber connection with the main control device, the main control device is arranged at the outlet of the transformer, the household commutation acquisition terminals are connected to a distribution network at the outlet side ofthe transformer, and each household commutation acquisition terminal is connected with a single-phase user. According to the utility model, the three-phase current of the power distribution network can be monitored, and when the unbalance degree of the three-phase current is greater than a set value, the household commutation acquisition terminal can be controlled to carry out commutation operation; remote monitoring is achieved by adopting wireless remote transmission to the monitoring terminal, the household phase-change acquisition terminal has an electric energy metering function and uploads electric energy data together, extra meter reading is not needed, labor force is saved, and working efficiency is improved.
