The invention discloses a three-phase intelligent watt hour meter control device which comprises a three-phase magnetic latching relay. The three-phase intelligent watt hour meter control device is characterized in that the three-phase magnetic latching relay is connected with a driving circuit, the driving circuit is connected with a single-chip microcomputer, the single-chip microcomputer and the driving circuit are respectively connected with a power source conversion module, and the power source conversion module is connected with a transient electricity taking energy storage device. The three-phase intelligent watt hour meter control device further improves the reliability of long-distance power-on and power-off, a switch special for a three-phase electric energy meter is developed, the large-power double-position magnetic latching relay is adopted, a special pulse power source module is designed, a secondary coil of the magnetic latching relay is electrically neutral under the conditions that the switch is normally powered on and normally powered off, the coil is electrified only when the power-on process is stopped, and position switch is achieved, so that the service life is prolonged and the reliability is improved. Difficulty, caused by damage of the externally-arranged switch of the electric energy meter, of electric bill retrieving and payment reminding is reduced, the possibility of service complaints is reduced, and unnecessary waste and consumption, caused by the fact that the coil of a release is electrified for along time, of electricity are avoided.
