Low Frequency Transformer Function mainly

Transformer functions are: voltage conversion; current conversion, impedance conversion; isolation; voltage regulator (magnetic saturation transformer), the transformer commonly used core shape generally E-type and C-type core, XED type, ED type.

Transformers can be divided into: distribution transformers, power transformers, transformer plants, sealed transformers, modular transformers, dry transformers, single-phase transformers, electric transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, Box Transformer Test Transformer Angle Transformer.

The most basic type of transformer, including two groups of wires around the wire, and together in an inductive way together. When an alternating current (with a known frequency) flows through one of the coils, the AC voltage with the same frequency is sensed in the other coil, and the magnitude of the induced voltage depends on the coupling and the magnetic The degree of chain.

Generally refers to the connection of AC power coil called "primary coil" (Primary coil); and across the coil voltage is called "primary voltage." The induced voltage in the secondary coil may be greater or less than the primary voltage, which is determined by the "turns ratio" of the primary coil and the secondary coil. Therefore, the transformer is divided into two types of step-up and step-down transformer.

Most of the transformers have a fixed core, which is wound once with the secondary coil. Based on the high permeability of the iron material, most of the magnetic flux is confined to the core, so that the two sets of coils can thus obtain a relatively high degree of magnetic coupling. In some transformers, the coil and the core between the two closely together, and its primary and secondary voltage ratio is almost the same as the number of turns of the coil. Therefore, the transformer turns ratio, generally can be used as a transformer boost or buck the reference index. As a result of this step-up and step-down function, the transformer has become an important subsidiary of modern power systems, to enhance the transmission voltage makes long-distance transmission of electricity more economical, as the buck transformer, which makes the use of more diversified, That said, no transformer, modern industry can not achieve the current development of the situation. Transformers are used in almost all electronic products, and the principle is simple but different depending on the use of different occasions (different purposes) transformer winding process will be different requirements. Transformer functions are: voltage conversion; impedance conversion; isolation; regulator (magnetic saturation transformer), the transformer commonly used core shape generally E-and C-type core.
