Intermediate Frequency Generator Motor Set （DVDF)
General Information:
Intermediate Frequency Generator Motor Set is an adjustable power generation system drivenby a synchronous generator driven by a motor. It is mainly used as a test powersource in transformer inductive withstand voltage, partial discharge andno-load tests. The output frequency of the unit is 50Hz, 60Hz, 100Hz, 125Hz,150Hz, 200Hz. By changing the excitation current of the generator, the outputvoltage of the unit is continuously adjustable, the adjustment accuracy ishigh, and the voltage change is smooth, which is very suitable for varioustests of the transformer. The output voltage of low-power units is generally 0~ 800V, and high-power units are generally designed from 0~3.15kV, 6.3kV or10.5kV. Special voltage grade products can also be designed according tocustomer requirements. This series of products is specially designed fortransformer test, and has the characteristics of convenient adjustment, goodwaveform and reliable performance.
