Many people do not know what types of transformers there are. As a professional manufacturer and exporter of power transformers in China, we can tell you the exact answer.

A transformer is a static electrical device that changes the voltage and current of the AC power supply without changing the frequency. It has two (or several) windings. At the same frequency, it converts the AC voltage and current of one system into another through electromagnetic induction. An electrical device through which electrical energy is transmitted by the alternating voltage and current of one (or several) systems. Usually, the AC voltage and current values ​​of at least two systems to which it is connected are different.

It can be seen that a transformer is an AC electrical device that works through electromagnetic induction. The main transformer system consists of coil, iron core, main transformer oil tank, transformer oil, pressure regulating device, gas relay, oil pillow and oil level gauge, pressure releaser, temperature measuring device, cooling system, submersible oil pump, etc. In addition, the main transformer is also equipped with a gas chromatographic online monitoring device to detect the dissolved gas in the transformer oil every week in order to judge the operation status of the equipment.

There are many ways to classify transformers: according to different uses, it can be divided into power transformers, industrial transformers and other special transformers for special purposes; according to the cooling medium of windings and cores, it can be divided into oil-immersed transformers and dry-type transformers; Different types of iron cores can be divided into core-type transformers and shell-type transformers; according to different voltage regulation methods, they can be divided into non-excitation voltage-regulating transformers and on-load voltage-regulating transformers; according to the number of phases, they can be divided into three-phase transformers and single-phase transformers. Transformer; according to the number of windings on the core column, it can be divided into double-winding transformer and multi-winding transformer; according to whether there is electrical connection between windings of different voltages, it can be divided into independent winding transformer and autotransformer, etc.
