High quality dry type transformers manufacturer: Several factors can affect power quality in transmission lines. These include: Load Characteristics: Non-linear loads can generate harmonics that distort the voltage and current waveforms, affecting the power quality. Transmission Line Length: Longer transmission lines have higher impedance, which can cause voltage drops and affect power quality. Faults on the System: Short circuits, ground faults, or equipment failures can lead to voltage sags, swells, or transients, impacting power quality. Switching Operations: The switching on/off of large loads or reactive power compensation devices can cause transient overvoltages that degrade power quality. Grid Interconnections: Interconnections between different power systems can introduce disturbances, affecting the power quality. See even more details at transformer core cutting line.

Why does the current source inverter need a larger transformer capacity? Current source inverter is a common type of inverter. Its control method adopts current loop control, which has the advantages of high precision and strong adaptability, and is widely used in industrial production. Due to the working characteristics of the current source inverter, a large transformer capacity is required for the following reasons: The current source inverter adopts the intermediate inductance: the current source inverter adopts the intermediate inductor, which can realize the phase difference between the output voltage and the current, so as to realize the frequency conversion control. However, since the intermediate inductor needs to withstand large current and voltage, it is necessary to select a transformer with a larger capacity to ensure the normal operation of the inductor.

The loss in magnetic flux in the transformer must therefore be minimized by providing a suitable mean between the primary and secondary windings. For this purpose, silicon steel magnetic cores are usually used. By using a core type transformer, magnetic losses are reduced and a greater amount of magnetic flux is conveyed between the primary and secondary coils, thereby increasing the transformer’s overall efficiency. Electrical materials play an important role in the field of engineering technology. Various technologies should be realized through certain equipment, and the equipment needs to be made of specific materials. Without corresponding materials, even technologies and products that are feasible in principle cannot be realized. The emergence of new materials can often bring significant technological progress.

With the development of the times, people’s demand for power supply and the reliability of power supply are increasingly high, so the smart grid has emerged accordingly.In the power system, the core and hub of the substation is the transformer.The function of the transformer is mainly to distribute and convert electric energy. The normal operation of the transformer directly affects the normal function of the substation.The intelligent operation of the transformer mainly involves the protection and status monitoring of the transformer, so as to achieve real-time monitoring of the transformer and ultimately ensure the safety and reliability of power supply.
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.
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.
