Power Transformer

Ezitown Transformers are used to convert AC voltage, AC current transmission power of a stationary electrical equipment. It is implemented according to the principles of power transfer by electromagnetic induction. Transformer on its use can be divided into power transformers, test transformer, instrument transformers and special purpose transformers: Power transformers for power transmission and distribution, power users and distribution of the necessary equipment; test transformer for electrical equipment for pressure (boost) test equipment; electrical measuring instrument transformer as a power distribution system, with the protection of the (PT, CT); special purpose transformer has smelting furnace transformers, welding transformers, rectifier transformers for electrolysis, small regulating transformers.
Power transformer is a static electrical device, is used to a certain value of the AC voltage (current) becomes the same frequency as another one or several different values ​​of voltage (current) devices. When alternating current is passed through the primary winding, it generates an alternating magnetic flux, alternating magnetic flux through the core role of the AC electromotive force is induced in the secondary winding. Secondary induction level and a secondary winding turns EMF much information, that voltage is proportional to the size and number of turns. The main role is the transmission power, and therefore, the rated capacity is its main parameters. Rated capacity is a manifestation of the power of conventional values, it is the characterization of the size of the transfer of power to kVA or MVA said that when the transformer rated voltage is applied, according to which, under specified conditions to determine the limits of temperature rise does not exceed the rated current. More energy-efficient power transformer amorphous alloy core distribution transformers, its biggest advantage is that the value of extra-low load loss. Ultimately able to ensure load loss value, it is the core issue throughout the design process to be considered. When the product structural arrangement, in addition to considering amorphous alloy core itself from external forces, but at the same time in the calculation of selected parameters must reasonably accurate amorphous alloys.
