The 1000KW power supply uses a dedicated rectifier transformer, and the oil is immersed in a cold copper wire package. In this set of equipment, the transformer model is ZS11-1500/10/2*0.8KV. The primary voltage of the transformer is 10KV, the secondary voltage is 2*750V, and the 12-pulse 6-phase output. The short-circuit impedance of the transformer ranges from 6% to 8%. The unloaded manual voltage regulator switch is installed on the high voltage side of the transformer, and the output voltage can be adjusted in the -5%, 0, +5% third gear.
