Dry type power transformer supplier by Canwin: 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.

Current source inverter has a higher power factor: The current source inverter has a higher power factor, which can achieve higher power factor correction, thereby reducing grid harmonic pollution. However, since a higher power factor requires larger capacitor support, a transformer with a larger capacity needs to be selected to meet the power supply requirements of the capacitor. Current source inverter needs additional power supply: The circuit of current source inverter needs additional power supply to ensure the normal operation of the current loop control. These additional power sources need sufficient capacity to support, so a transformer with a larger capacity needs to be selected to meet the power supply requirements. Therefore, the current source inverter needs a larger transformer capacity to ensure the normal operation of the intermediate inductor, support the power supply of the capacitor and meet the power supply requirements. When selecting a transformer, it needs to be selected according to the actual electrical parameters and performance requirements to ensure the normal operation and stability of the inverter.
Heating of Cables, Motors, and Transformers: Poor power quality can lead to excessive heating in cables, motors, and transformer core cutting machine. This can accelerate the ageing of these components, shorten their lifespan, and potentially lead to catastrophic failures. Maintaining high power quality, including minimizing voltage unbalances, is critical for ensuring the efficient operation of electrical equipment and avoiding the potential negative consequences associated with poor power quality. In conclusion, maintaining high power quality is of paramount importance for the optimal performance and longevity of transformer equipment. High-quality power ensures efficient energy consumption, reduces operational costs, and extends the lifespan of the equipment. It also minimizes the risk of malfunctions, data corruption, and excessive heating of cables, motors, and transformers – issues often associated with poor power quality.

The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When air cooled naturally, the transformer can run continuously for a long time under rated capacity. When forced air cooling, transformer output capacity can be increased by 50%. Suitable for intermittent overload operation, or emergency overload operation; Because the load loss and impedance voltage increase greatly during overload, it is in non-economic operation state, so it should not be in continuous overload operation for a long time.Welcome to inquiry price for dry type substation transformer.

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.

Impedance voltage (%): Short-circuit the secondary winding of the transformer and slowly increase the voltage on the primary winding. When the short-circuit current of the secondary winding equals the rated value, the voltage applied on the primary side is the impedance voltage. It is usually expressed as a percentage of the rated voltage. Phase number and frequency: Three-phase is represented by S, and single-phase is represented by D. The frequency f of China’s national standard is 50Hz.There are countries abroad with 60Hz (such as the United States).I. Temperature rise and cooling: The difference between the temperature of the transformer winding or upper oil layer and the temperature of the surrounding environment is called the temperature rise of the winding or upper oil layer. The limit value of the temperature rise of the oil-immersed transformer winding is 65K, and the temperature rise of the oil surface is 55K.There are also various cooling methods: oil-immersed self-cooling, forced air cooling, water cooling, tube type, sheet type, etc.
