Non-excitation tap switch applies to oil-immersed transformer with 50Hz or 60Hz of rated frequency. In case of no excitation in transformer (i.e. no winding is charged), the switch can be operated manually or electrically to change the tapping position and further to change the transformation ratio, and by this means, secondary voltage can be adjusted or stabilized.
Specific introduction:This series of switches is composed of the main body of the switch and the operation turning organ. They are applicable to the oil-immersed transformers with the frequency of 50Hz, 60Hz. They ca be fixed on the body of the transformer or on the box-cover, and be tapped, regulated and changed under on excitation condition.
1.This kind of electric off circuit tap changer applies to the single-phase, three-phase, combination oil-immersed transformer of electrical power .
2.The frequency of 50HZ,60HZ,rated voltage of 10KV,35KV,rated current of 30A~250A;the voltage-regulating places are: central part, neutral
point, can be directly fixed on the box-cover of the transformer
3.under the non-excitation condition regulating and changing.
