The utility model is achieved in that
A kind of single three-phase double-purpose switching device shifter of generating set, the stator of generator frame is provided with six windings, six windings respectively with circuit board on change over switch on six roots of sensation electric wire be connected, six windings of the upper control of change over switch are exported single-phase voltage by socket; Six winding no-voltage outputs of the meta control of change over switch; Six windings of the next control are crossed socket output three-phase voltage, all are connected with earth connection on the stator of described generator frame and the socket.
Be provided with the circuit breaker of short-circuit protection between six windings of above-mentioned stator and the change over switch.
The socket of above-mentioned output three-phase voltage is five holes industry socket.
The socket of above-mentioned output single-phase voltage is that unskilled labourer's industry socket is or/and Europe is slotting.
Be provided with the voltmeter that detects voltage between above-mentioned change over switch and the socket.
The advantage that the utility model is given prominence to compared to existing technology is:
1, the utility model can be realized the conversion between voltage 380V and the 220V, and generator all can use at 220V and 380V voltage, both can do industrial, also can do civilian, highly versatile, applied widely;
2, circuit breaker of the present utility model can play the short-circuit protection effect;
3, the utility model can increase the power output of 220V, and the power output of 220V and 380V is full power.
