Transformers is a mutual Electromagnetic induction, transform voltage, current, and impedance devices. Function of a transformer are: voltage transformation; current transformation, impedance transformation; isolated voltage regulator (transformer magnetic saturation), and so on.
Classification of common transformers can be summarized as follows:
(A) by means of cooling:
(1) dry-type transformers: relying on natural air convection or increase the fan cooling, electricity used for high-rise buildings, high-speed charging site and partial lighting, electronic circuits, small capacity transformers.
2) for oil-immersed Transformers: rely on oil as the cooling medium, such as oil-immersed self-cooled, oil-impregnated oil-air cooling, water cooling, forced oil circulation.
(B) by winding forms:
(1) two-winding transformer: used to connect two of the power system voltage levels.
(2) three-winding Transformers: generally used for electric power systems in substations, connect three voltage levels.
(3) auto-biandianqi: used to connect different voltages of the power system. Also can be used as a normal transformers after the rise or drop.
(C) the iron core form:
(1) core transformer: used in high voltage power transformers.
(2) non-Crystal alloy transformer: amorphous alloy iron core transformer is a new type of magnetic material, no load current decreased by about 80%, is currently the preferred distribution transformer energy saving effect, especially suitable for rural power grid load rate and developing regions places lower.
(3) shell type transformers: special transformer for high current, such as electric arc furnace transformers, welding transformers; or for use in electronic equipment and televisions, radios and other power transformers Shanghai Hong-box-type transformer.
New terminals of a transformer, has been widely used in electrical and electronic engineering industries in the world: large transformers and so on. Transformer terminal blocks, structure designing balanced wiring is convenient, characteristic of screw connections are secure, can be installed quickly and easily on 2X10mm Rails. Products designed to comply with international standards such as IEC 60947-7-1.
Elinker electric specializes in development and manufacture of terminals, the company has advanced research and development of technology and research and development equipment, its production of PCB terminal blocks are well received by users, gradually swell in connector industry situation in the current outcrop.
