The damage of precision electronic element is avoided, avoids unnecessary property loss.
The object of the present invention is achieved like this：A kind of switch cubicle tests bench control system, including is connected to three phase mains
Isolating transformer, four-way power supply module and alternating current 220V power output end on line, the isolating transformer are defeated including three groups
Enter coil and six groups of output windings, every group of input coil corresponds to two groups of output windings, and one group of output end is made in two groups of output windings
For ac voltage output, another group of output end is serially connected with resistance as alternating current output end, in the four-way power supply module
Four output ends respectively as four different pressure values DC voltage output end.
As the further restriction of the present invention, alternating current output end sets two groups in the isolating transformer, and output is not
With the alternating current of current value, two groups of alternating current output ends coordinate the series resistor of different resistances.
As the further restriction of the present invention, the alternating current 220V power output end sets two groups.
As the further restriction of the present invention, be also associated with the three-phase power line three-phase four eyed socket, three sockets,
Two sockets and voltmeter.
As the further restriction of the present invention, in the isolating transformer, ac voltage output is also other is connected to voltmeter.
As the further restriction of the present invention, ac voltage output output 110V electric currents are electric in the isolating transformer
Press, alternating current output end exports 5A alternating currents and 1A alternating currents, four-way power supply module difference respectively in isolating transformer
220V DC voltages, 110 DC voltages, 48V DC voltages and 24V DC voltages are exported, the three-phase four eyed socket can be defeated
Go out 25A electric currents, the exportable 10A electric currents of three sockets, two sockets.
Compared with prior art, the beneficial effects of the present invention are by the present invention in that with isolating transformer and four tunnels
Power module output multi-channel different voltage or current signal so that the electric current of output, voltage need not manual adjustment, while also keep away
That exempts from repeats, and without adjusting transformer, directly tests；And the time is saved, is originally tested the time of a switch cubicle, it is existing
It is doubled production efficiency two switch cubicles can be tested.The present invention can be used in switch cubicle test.
