Excellent slitting line machine producing company: Why do transformers use silicon steel sheets as iron cores? Transformers use silicon steel sheets as iron cores because silicon steel sheets have high magnetic permeability and low resistance. In a transformer, the iron core mainly undertakes the role of conducting magnetic flux. Therefore, the magnetic permeability of the iron core is very critical. Silicon steel sheet is a specially treated steel with very high magnetic permeability, can effectively conduct magnetic flux, and can reduce the loss of magnetic flux and eddy current loss. In addition, the transformer will produce electromagnetic induction phenomenon during the working process, which will generate eddy current in the iron core. These eddy currents cause loss of energy and heating of the core, reducing the efficiency of the transformer. The silicon steel sheet has low resistance characteristics, which can reduce eddy current loss and improve the efficiency of the transformer. Therefore, using silicon steel sheet as the material of the transformer core can improve the efficiency of the transformer, reduce energy loss, and reduce heat generation of the transformer, thereby prolonging the service life of the transformer.

What is eddy current? What are the disadvantages of eddy current generation? Eddy current refers to a kind of current generated in the conductor, which is the induced current caused by the change of the magnetic field. The eddy current forms a circular current flow path in the conductor, and this current forms a motion state similar to an eddy current inside the conductor, so it is called an eddy current. The generation of eddy currents has the following disadvantages: Energy loss: Eddy currents create circular currents in conductors, which generate heat as they flow continuously in conductors. Since the generation of eddy currents is caused by changes in the magnetic field, in equipment such as transformers and motors.

A China slitting line produces longitudinal cuts in a master coil of steel to predetermined narrower widths. These smaller coils are then sent to downstream operations such as metal stampers, tube producers or roll forming houses that will use the material in their final product. Customized slitting line machine equipment mainly includes the following: Loading trolley, double support uncoiler, feeding device, traction leveling machine, trimming shearing machine, deviation correction feeding device, longitudinal shear line, waste edge winder, feed rack, pre separation device, tensioner, feeding roller, winding shearing machine, steering drum, rear axle, discharge trolley, winding auxiliary support, hydraulic system and electrical system, etc.
As a result of mutual inductance, a transformer produces a transformed voltage or current when the magnetic flux produced by one winding (primary winding) links with another winding (secondary winding). There is a magnetic coupling between these two windings, and they are electrically isolated. In addition, magnetic reluctance is also known as opposition to magnetic flux flow. If, for example, the magnetic flux produced by a primary winding passes through air or any nonferrous material in order to reach a secondary winding in a transformer, it would result in a reduction in magnetic flux. Due to the high reluctance of air or nonferrous materials, it will reduce magnetic flux. Discover more details on https://www.canwindg.com/
The main pillar of the smart grid is the smart substation, which is not only an important hub for power transmission and distribution, but also directly affects the operational and monitoring capabilities of the smart grid through its operational safety and stability. Through the network, information can be exchanged, and the transformer can share information with the process layer and the station control layer. On the premise of ensuring product performance, the integration of monitoring, control, measurement, protection, and metering is designed to achieve the integration of transformer components with actuators, sensors, and transformers.
Insulation level: There are standards for insulation levels. The insulation level of a transformer with a rated high voltage of 35 kV and a rated low voltage of 10 kV is represented as LI200AC85/LI75AC35, where LI200 indicates that the transformer has a high-voltage lightning impulse withstand voltage of 200 kV, a power frequency withstand voltage of 85 kV, and a low-voltage lightning impulse withstand voltage of 75 kV, and a power frequency withstand voltage of 35 kV. The current insulation level of Aux High-Tech Co., Ltd.’s oil-immersed transformer products is LI75AC35, indicating that the transformer has a high-voltage lightning impulse withstand voltage of 75 kV and a power frequency withstand voltage of 35 kV. Because the low voltage is 400 V, it can be ignored.
Maintaining high power quality requires careful management of harmonic currents and other potential disturbances on transmission lines. This is crucial not only for the efficient performance of transformer core cutting machine but also for the overall reliability and safety of the power system. Voltage unbalance is a significant power quality issue that can severely affect the efficiency of electrical equipment. It occurs when the voltages or currents in a three-phase system are not equal in magnitude or are not separated by exactly 120 degrees. Voltage unbalance can cause several problems in electrical equipment. For instance, it can lead to a decrease in the efficiency of electric motors by causing a reduction in torque and an increase in vibration and noise. This not only affects the performance of the motor but also shortens its lifespan. Similarly, voltage unbalance can also reduce the efficiency of transformers, leading to increased losses and overheating.
