NO.5

No.5 transformers has been widely used in power system since its invention in Germany in 1885. The application of the transformer includes power generation, power transmission, power distribution and power management. Among them, power transmission and power distribution are the main application fields of no.5 transformer.

Power transmission refers to the process of transmitting electrical energy from the generating station to the required load. The transmission mainly use high-voltage transmission lines to transfer power. The no.5 Transformer is used for voltage transformation in this process, which is used to step up the voltage from the generator to the transmission line, and also step down the voltage from the transmission line to the distribution line. Generally speaking, the high-voltage power line must pass through a no.5 transformer.

Power distribution is to deliver electrical energy to the final user from the power grid, distribute the power from substation to the final user. Here the no.5 transformer is used to step down the voltage from the power grid to the level that can be accepted by the user. Generally speaking, every transformer station must be installed with a no.5 transformer.

In addition to power transmission and distribution, no.5 transformers can also be used in industrial automation. With the development of science and technology, energy-saving electrical appliances are more and more widely used, the working voltage of these electrical appliances can not directly match the power voltage from the power grid, so they can\'t be directly connected to the power grid. That\'s why the no.5 transformers are installed in the industrial automation control system, and the voltage is adjusted according to the actual needs of the electrical appliance.

The working principle of the no.5 transformer is as follows: there are a primary coil and a secondary coil in the transformer, and both of them are wound around a common core. When a certain alternating voltage is applied to the primary coil, a magnetic field is generated in the core, and the secondary coil will induce a certain voltage according to the transformer principle.

The size of the voltage induced in the secondary coil is proportional to the turns ratio P/S. Therefore, the no.5 transformer can be used for step-up and step-down of voltage, so as to achieve the purpose of voltage conversion and matching.
