Transformer manufacturers in Hebei, Henan and transformer factory people Flush recognition and weekends khaki then synonymous with Chicken and Duck sermon together using blanket transformer mutual inductance principle. The transformer is using the principle of electromagnetic induction means to change the AC voltage, the main member is a primary coil, a secondary coil and a core (magnetic core). The main features are: voltage conversion, the current conversion, impedance transformation, isolation, voltage regulator (magnetic saturation transformers) and so on. Can be divided according to purpose: distribution transformers, power transformers, sealed transformers, modular transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, furnace transformers, rectifier transformers. Transformers in the electrical equipment and radio circuits, the transformer used for lifting voltage, impedance matching, security isolation. In the generator, whether a coil or magnetic field moves through the magnetic field moves through the stationary coil, the induced voltage in the coil can in both cases, the value of the magnetic flux are the same, but there is the number of the magnetic flux intersecting the coil chain change, which is the principle of mutual induction. Transformers is a use of electromagnetic induction interaction, transform voltage, current and impedance of the device. Primary Voltage: 440V / 415V / 380V / 220V / 200V (customer specified) secondary voltage: 380V / 220V / 200V / 110V / 100V / 36V / 24V / 12V / 6.3V / 3.6V (customer specified) Operating frequency: 50 / 60Hz Insulation class: T40 / B (130 ℃); T40 / F (155 ℃); T40 / H (180 ℃) @ 50Hz & customer specified temperature limits: includes two sets of coil wire is wound, and another to inductively said co-together. With the continuous development of transformer industry, more and more enterprises to enter the transformer industry, there are many companies come to the fore, such as Ming Yuan transformer was founded in the early 2000s to form a joint stock company specializing committed by transformers, reactors, filters and other research and development, manufacturers, after nearly a decade of development has become one of the few industry leader and pioneer of advanced technology. The main products are: Transformers series (single-phase, three-phase power transformers, single-phase and three-phase auto-transformers, machine tool control transformer, autotransformer start saving transformers, Scott transformers, three phase to single phase, single phase transition Three-phase, UPS transformers and other non-standard transformer), reactor series (inverter input, output reactor, DC smoothing reactors, series-parallel reactor, filter reactor, hollow reactor, etc.), filter series (inverter Dedicated input filter and output filter, sine filter) products are widely used in electricity, metallurgy, textile, machinery, wind power, steel and other industries, praised by customers. When an alternating current (having a known frequency) flow in the one set of coils, the coils in the other group having an AC voltage is induced at the same frequency, depending on the magnitude of the voltage induced in the two coils and the magnetic cross-coupling the extent of the chain. http://www.zgbyqw.com generally refers connected to AC power coil is called the primary coil; while the voltage across this coil is called the primary voltage. Induced voltage in the secondary coil may be greater or less than the primary voltage is determined by the primary coil and the secondary coil turns ratio between the decision. Therefore, the step-up transformer is divided into two zones with the step-down transformer. Rated current Dielectric strength: PS 2500V / 1min without breakdown and flashover PE 2500V / 1min without breakdown and flashover Insulation resistance: ≥100MΩ Cooling: air from the cold (air-cooled) link mode: Y / YY / △ △ / Y have the majority of the fixed iron core transformer, the primary and the secondary is wound on a coil. Magnetic iron-based high-conductivity material, most of the magnetic flux confined to the core, therefore, to take two sets of coils can get a very high degree of magnetic coupling. In some transformer, between the coil and the core of both closely, its ratio of primary and secondary voltage is almost identical between the two coil turns ratio. Core does not exceed 80K (thermometer method), the coil temperature does not exceed 80K (platinum resistance method). Working noise: less than the most basic form 60dB (with the transformer at a horizontal distance from point 1 m) of the transformer, so that the transformer turns ratio of the transformer and can be used as a step-up or step-down reference. Because of this boost and buck the features that make the transformer has become one of the important adjunct of modern power systems, improve the long-distance transmission of electricity transmission voltage makes more economical, as the step-down transformer, which makes electricity use has become more diversified, you can so that no transformers, industrial status quo can not achieve real development. Transformers have to do the test and its use, called the test transformer, respectively, can be divided into inflatable, oil-immersed, dry-type transformers and other tests, are power plants, power supply bureau and research institutions and other users to make exchanges The basic test equipment pressure test by the standards of the State Bureau of Quality Supervision, for a variety of electrical products, electrical components, insulation materials insulation strength test specified voltage. Ming Yuan transformer core transformer is made of high quality cold-rolled silicon steel low-loss, high-speed punch after punch, with a small glitch, the rules uniform laminations neat appearance, low loss, high quality insulated wire coil, made by special machines around the circle shaped, rectangular and other shapes, with a wound tight, neat, good flatness, beautiful appearance. Metal clamps embalmed, transformers overall pre-bake - vacuum impregnation - heat drying curing process, the transformer winding and core firm as a whole, greatly reduces the run-time noise, improve the insulation performance of the transformer.
