Regulate Voltage Well High Efficiency And Energy Saving Good Quality Property Iron Core

  Because the sheet core can reduce another type of iron loss, "eddy current loss". When the transformer works, there is an alternating current in the coil, and the magnetic flux it produces is, of course, alternating. This changed magnetic flux generates an induced current in the core. The induced current generated in the iron core circulates in a plane perpendicular to the direction of magnetic flux, so it is called eddy current.

   Eddy current losses also heat up the core. In order to reduce the eddy current loss, the iron core of the transformer is filled with silicon steel sheets insulated from each other, so that the eddy current passes through a small cross-section in the narrow circuit to increase the resistance on the eddy current path; at the same time, the silicon in the silicon steel increases the resistivity of the material and also plays a role in reducing the eddy current.

  The core used as the transformer is generally made of cold-rolled silicon steel sheet with a thickness of 0.35mm, and it is cut into a long piece according to the size of the required core, and then overlapped into a Japanese zigzag or mouth-shaped shape. Logically speaking, if the eddy current is reduced, the thinner the thickness of the silicon steel sheet, the narrower the spliced piece, the better the effect. This not only reduces eddy current losses, reduces temperature rise, but also saves the material used for silicon steel sheets. But in fact, when making silicon steel sheet cores. It is not only from the above-mentioned favorable factors, because the production of the iron core in this way will greatly increase the man-hours, and also reduce the effective cross-section of the iron core. Therefore, when using silicon steel sheet to make transformer core, it is necessary to start from the specific situation, weigh the pros and cons, and choose the best size. Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of silicon (silicon is also known as silicon) steel, and its silicon content is 0.8~4.8%.
