China wholesale Mg Set - Motor-Generator Sets for Transformer Factory – Trihope Detail:

◆For Transformer Testing

◎No-Load Testing

Users can choose 50 or 60Hz or output two kinds of frequency. MG sets change the frequency by adjusting the speed.Dc machine can adjust the speed, so when the generator is required to output several frequency power supply, such as 50Hz, 60hz, then the motor can adopt dc motor. In recent years, with the maturity of inverter technology, more and more frequency converters are used to achieve the requirement that the MG sets output two or more frequency. Several configurations are available:

Sr	Motor	Generator
1	300kW 50Hz	500kVA 200Hz
2	800kW 50Hz	2000kVA 200Hz
3	1000kW 50Hz	4000kVA 200Hz
4	1500kW 50Hz	5000kVA 200Hz
5	3050kW 50Hz	7500kVA 200Hz
6	3050kW 50Hz	7500kVA 200Hz

◎Induced Voltage Testing

For interturn voltage resistant test, it needs Times frequency power supply, which is higher than the rated voltage of the transformer. It can adopt 100Hz, 150Hz and 200Hz MG set, which is safe and reliable.

◆ Dockyard shore power

For ship repair or shipbuilding in a shipyard, shore power with the same frequency as shipboard electrical equipment is required. 50 Hz power supply can be provided by the mains, but 60 Hz power supply is generally obtained by a 12‐ pole synchronous generator driven by a 10‐pole synchronous motor. A stationary variable frequency power supply is also used to obtain 60 Hz power supply, but the waveform, dynamic performance, life and other aspects are inferior to the

MG set.

◆Other MG Sets

There are some special purpose power supply equipment, such as the dredger shaft system, motor test system, compressor test system, and so on.
