The first is the question of why phase shifting is used. This is because the transformer requires a larger number of pulses for high-power rectification equipment. There are an increasing number of applications with pulse numbers of 18, 24, 36, etc., which must be set on the primary side of the rectifier transformer. Phase shifting windings are used to perform phase shifting. There are three ways to connect the phase-shifting winding and the main winding, namely zigzag line, hexagon and extended triangle.
The voltage regulation method of the rectifier transformer also differs according to the application scope. For example, the voltage regulation range of the rectifier transformer in the electrochemical industry is much larger than that of the electric furnace transformer. For chemical salt electrolysis, the voltage regulation range of the rectifier transformer is usually It is 56%--105%. For aluminum electrolysis, the voltage regulation range is usually 5%--105%. Rectifier transformer is the power transformer of rectifier equipment. The characteristic of the rectifier device is that the primary side inputs current, and the secondary side outputs DC after passing through the rectifier. Variable current is a general term for the three working modes of rectification, countercurrent and frequency conversion, and rectification is the most widely used one.
Let's talk about the working principle of the rectifier transformer. A transformer is a device that converts AC voltage based on the principle of electromagnetic induction. Transformers generally have two independent windings, the primary and the secondary. These two windings share an iron core. The primary winding of the transformer is connected to the AC power supply, and the alternating current flows through the winding to generate magnetic potential, so there is alternating magnetic flux in the closed core. The primary and secondary windings cut the magnetic lines, and the alternating current of the same frequency can be induced in the secondary. The turns ratio of the primary and secondary windings of the transformer is equal to the voltage ratio.
