Abstract

Unlike to prior art, in the invention, series connecting additional voltage of an auxiliary transformer to the single-iron-core 12P rectification transformer to balance Y-delta voltage and obtain high-voltage single-winding power transformer. This product overcomes the bias that it is hard to process the Y / delta winding number ratio as 1:3, and reduces loss consumption than the conjugated or dual-iron-core 12P rectification transformer.

Description

1 Technical Field The present invention relates to the technical field of high-power rectifier transformers 2 background technology 2.1 Introduction to the "China Chlor-Alkali Rectification Technology Advanced Training Course" in October 2003 2.1.1 Chlor-Alkali Association's choice of equivalent rectification phase number Since the frequency of the higher harmonic current generated by the rectifier equipment mainly depends on the number of rectified phases of the rectifier equipment (that is, the number of rectified pulses P), and the absolute value of the higher harmonic current I n It is inversely proportional to frequency. Therefore, increasing the number of equivalent rectified phases is the most effective measure to eliminate low-frequency harmonic currents with large absolute values. The rectifier circuits used in medium and large rectifier equipment are mainly three-phase bridge type and double reverse star type with balanced reactors. When using a double reverse star cir...
