Primary coil voltageDesign serial numberMagneticDry (no such mark for oil immersion)Voltage adjusterIntroduction to magnetic voltage adjusterThe magnetic voltage adjuster is called controlled transformer, and it is a kind of voltage adjuster without mechanical transmission and contact, which can realize smooth infinite variable voltage adjustment under loading conditions. The voltage adjustment is controlled by D.C. excitation, and automatic enclosed control is realized based on different control signals.Structure of the magnetic voltage adjuster is similar to general transformer, and is the only structure made up of transformer and saturated reactor. It is comprised of 4 iron core columns and 4 windings; namely, primary winding WB1 and secondary winding WB2, saturated reactor working winding WG and D.C. control winding WK. The voltage adjustment scope specified in the voltage adjuster (such as high-voltage adjustment scope of TDH-2000: 5-35V) is for the rated loading resistance (rated loading resistance RN=U2/12=6.12×10-3Ω for TDH2-200). If the loading resistance is not equal to the rated value, the voltage adjustment scope will be correspondingly changed, especially at the lower limit of voltage adjustment. For the magnetic voltage adjuster includes the function of saturated reactor, the reaction winding has the function of limiting current, and sound current falling features is achieved. The voltage adjuster is not applicable for voltage adjustment under unloading conditions. For changes of U2 is small, the voltage adjustment scope is small under unloading conditions.With the function of the saturated reactor, the loading voltage waveform is abruptly changed, which is related to the output power.Rated input power, output voltage scope, loss, unloading, loading, D.C. control power, D.C. control current
