What are the functional characteristics of the transformer?

Release date:2018-12-20 17:13:54

Transformers are used in electrical equipment and wireless circuits. Transformers are often used for lifting voltage, matching impedance, and safety isolation. In the generator, whether the coil motion passes through the fixed coil through the magnetic field or the magnetic field, the potential can be induced in the coil. In both cases, the value of the magnetic flux is constant, but the number of magnetic fluxes intersecting the coil is Change, this is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance. The most basic form of a transformer consists of two sets of coils wound with wires and they are inductively coupled together. With the continuous development of the transformer industry, more and more enterprises have entered the transformer industry, and many companies have emerged. For example, the transformer was founded in the early 21st century. The joint venture shares a professional company dedicated to R&D and production of transformers, reactors and filters. After nearly a decade of development, it has become one of the few leading technology pioneers and pioneers in the industry. The main products are: transformer series (single-phase, three-phase power transformer, single-phase and three-phase autotransformer, machine tool control transformer, start autotransformer, energy-saving transformer, Scott transformer, three-phase to single-phase, single-phase change Three-phase, UPS transformers and other non-standard transformers), reactor series (inverter input and output reactors, DC smoothing reactors, series-parallel reactors, filter reactors, air core reactors, etc.), filter series (inverter Special input filter, output filter, sine wave filter) Products are widely used in electric power, metallurgy, textile, machinery, wind power, steel and other industries, and are well received by customers. When an alternating current (having a certain known frequency) flows to one of the coils, an alternating voltage having the same frequency is induced in the other coil, and the magnitude of the induced voltage depends on the two coil coupling and the magnetic flux. The extent of the chain. Generally speaking, a coil connected to an AC power source is called a primary coil; and a voltage across the coil is called a 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 between the primary coil and the secondary coil. Therefore, the transformer is divided into two types: boost and step-down transformers.
