hree-phase power transformers

Transformers can be seen in some power plants and power transmission places. Transformers can convert electrical energy into high-voltage current in the process of power transmission, which can reduce the loss of belt energy during the transmission process and play a good role in saving energy. In this way, some power plants far away from residents can carry out power transmission during the power transmission process.

In electrical equipment and wireless circuits, transformers can be used as voltage rise and fall, impedance matching, and safety isolation. With the continuous development of the transformer industry, more and more companies have entered the transformer industry. At the same time, transformer products are mostly used in electric power, metallurgy, textile, machinery, wind power, steel and other industries, which are well received by customers.

Transformers can be used for a wide range of purposes. Transformers are inseparable everywhere. In production and life, most of the electrical equipment used has transformers. Most of these transformers are integrated in the circuit. We can't see the transformer without disassembling the transformer. , But what we can see are some external devices that are matched with the device.

Three-phase power transformer In the power system, the transformer used to transform three-phase AC voltage is called a three-phase power transformer. Power transformers work on the principle of electromagnetic induction, so the most basic structural components are electrical circuits and magnetic circuits. The circuit part of the transformer is the winding.

For a step-down transformer, the connection with the system circuit and power supply is called the primary winding, and the load is connected to the secondary winding. The iron core of the transformer constitutes its magnetic circuit, the iron core is composed of an iron yoke, and the iron core is composed of a winding sleeve on the iron core column. In order to reduce the eddy current and hysteresis loss of the transformer, silicon steel plates coated with insulating paint film are alternately formed into cores.

The core is the main part of the magnetic circuit in the transformer. Usually it is made of hot-rolled or cold-rolled silicon steel plate with high silicon content and thickness, and the surface is coated with a three-phase transformer with insulating paint. The core is divided into core columns and horizontal sections. The iron core sleeve partially has windings; and the iron core sleeve has windings. The horizontal piece is used to close the magnetic circuit.

The basic form of the core structure is a heart shape and a shell shape. The winding winding is the circuit part of the transformer, which is wound with double-wire packaging (paper packaging) insulated flat wire or enameled round wire. Fuel tank The fuel tank is composed of a tank body, a tank cover, a radiator and a drain valve. Its main function is to connect the transformer into a whole and dissipate heat. Inside are windings, iron cores and transformer oil.
