The transformer's core is the principal part of any electronic and electrical system. By its efficiency, the effectiveness of the secondary and primary windings depends on how the electrical impulse reaches the system. Many people know about the equipment's estimated scheme of operation, can call the mechanism's key features. Yet the question of why the core of the transformer is constructed from separate plates finds no answer.
The truth is that there is an electrical impulse applied to the material, and there seems to be no difference whether it is fixed or multiple. Therefore, in a simple language, we will seek to illustrate as easily as possible why the transformer core is constructed from thin sheets, why it is necessary and how the length, width, and conductivity coefficients are chosen correctly.
Transformer Core Features: Principle
You need to understand the very nature of the structural component before addressing the question why the transformer core is being constructed from plates. The mechanism's aim is to concentrate the magnetic flux that goes into the system. The values are obtained by constant and corresponding measurements resulting from processing. Without the existence of a core, it would be difficult to measure the device's technical characteristics including the coefficient of error, performance and more.
Why are transformer cores made of different plates-improving the magnetic properties of these metals and elements.
The system consists of solid tiles, of varying thicknesses. You can make various product variations: from 0.5 to 0.35 millimetres, but you can also find another sheet of thickness. Cold-rolled and hot-rolled variants are distinguished by improved magnetic circuit characteristics but the assembly of the unit involves different work skills.
Even the toroidal ones can be dialed from a spiral folded cord. In this method assembling involves positioning the secondary winding, while the primary winding's inductive resistance can decrease dramatically (tends at zero values), which can improve the precision of the job.
Why is the transformer's magnetic core constructed from different sheets, if the system can have more than one hundred volts and amperes and an operating frequency of 50 Hz-enhancing the efficiency of the work and ensuring uninterrupted electricity supply for processing.
Devices from thin and different core plates need to be assembled-this eliminates vortex losses. They become deformed under the influence of magnetostriction on the transformer, the performance is decreased, high-quality power measurements and other technological features are impossible to carry out.
Yet through experimental calculations, we find that the values of mechanical vibrations are different, because the noise produces higher harmonics. It is clear why the transformer's core is made from different sheets and that only high quality metals are used to produce it.
Having learned how the core works and understanding its main technical characteristics, materials of manufacture and design features, you can understand yourself why the core of a modern transformer is assembled from separate sheets of iron. In order to understand this, you need to trace the opposite. If the core of the equipment was made of a solid solid piece of metal, this would lead to the appearance of an alternating magnetic field.
This in turn encourages the formation of a substantial magnetic field near the core. Emerging additional currents are not needed for stable and high-quality operation of the vehicle, they only complicate the processing of data by the secondary and primary windings.
