TESGZ three-phase high-power variable voltage transformer

The variable voltage transformer also has the characteristics of output voltage adjustment from zero voltage, strong instantaneous overload capacity, small no-load current and no-load loss, high efficiency, low noise, long service life, etc. It is suitable for all kinds of inductive, capacitive and resistive loads.

Structural features

♦ Three-phase autocoupling design.

♦ Iron core structure: three-phase column type iron core is adopted.

♦ Coil structure: The coil is divided into common winding and series winding. The series winding serves as the input winding and is located in the inner layer; the common winding serves as the voltage regulating winding and is located in the outer layer.

♦ Voltage regulation: The servo motor drives the roller brush set through the variable speed mechanism, sliding up and down along the surface of the outer coil to realize voltage regulation.

♦ Protection device: the side of the variable voltage transformer is equipped with upper and lower L×19-131 travel switches, as the limit protection of thevariable voltage transformer.

 Sequence controller is installed on the top of TYDZ-type variable voltage transformer, driven by variable speed mechanism, and seven sets of L×W5-11G2 travel switches are configured inside, providing upper and lower limit and process limit functions, which can be used by the user at his/her own choice.
