| titleOfInvention | Three-phase imbalance commutation device |
| abstract | The utility model discloses a kind of three-phase imbalance commutation devices, including：Current acquisition unit, main control unit, voltage zero-cross detection unit, thyristor cell and switch unit；Current acquisition unit acquires the electric current of three-phase；Main control unit exports commutation control signal also according to default commutation rule according to Current calculation tri-phase unbalance factor in voltage over zero；Thyristor cell includes driving circuit and thyristor, and thyristor connects each phase and single-phase load of three-phase；Switch unit includes mechanical switch and buckle releaser, and mechanical switch connects each phase and single-phase load of three-phase, and buckle releaser drives closure or the disconnection of mechanical switch.The monitoring of three-phase imbalance may be implemented in the utility model and the phase-change switch by being made of mechanical switch and buckle releaser carries out commutation, reach the quick commutation of not power down of single-phase load, also greatly to reduce electric arc in voltage over zero switching to improve safety and the service life of device. |
