Product synopsis:
Equipped with on-load changer tap-changer is called the transformer on-load changer transformer. Transformer on-load changer to elicit from transformer winding through several points joint on-load changer tap-changer, ensure not cutting load current situation, transform points, to change its effective pick position of turms, namely changed transformer to output voltage variable pressure than constant purpose. In the process of the transformation points after transition resistance to commonly used in energy absorption tent-pins circulation current.
Transformer on-load changer mainly used for:
A, stable in every load center of power, in order to improve the quality of power supply voltage;
B, as two network contact between transformer on-load changer, using the load distribution network; between
C, used in belt load regulation current and power, the power to improve production efficiency places;
D, used to must be strictly controlled voltage occasions, such as electronic industry, medicine, etc of power transformer used.
SZ9 / SZ11 on-load changer transformer
