The utility model discloses a low -voltage transformer area three -phase unbalanced load adjusting device, including master controller and a plurality of phase converter, the master controller corresponds with a platform district transformer and is connected, and the master controller include 233M radio communication partially, three phase current collection part, data processing part, display element part, the phase converter concatenates between switch board and subscriber circuit, and the phase converter includes that 233M radio communication part, three phase current gather part, three -phase execution unit, commutation protection part, and the master controller is communicated through 233M wireless module with the phase converter. The utility model discloses equipment is reliable, andwhen the unbalanced three phase problem appeared in the circuit, the real time kinematic that carries on that can not only be automatic adjusted, but also can point out staff operating condition themonitoring, in case special circumstances appears, can in time react, and commutation time weak point in the whole adjustment procedure, service reliability, security height.
