Quality transformer core cutting line 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.

Rising temperature: The capacity of the transformer will decrease as the temperature rises. Therefore, it is necessary to consider the appropriate heat dissipation method and heat dissipation area when designing the transformer to ensure that the temperature rise of the transformer does not exceed the allowable range. Connection method: Different transformer connection methods, such as star, delta, etc., will also affect the capacity of the transformer. For the star connection, the capacity of the transformer can be increased by about 3 times; for the delta connection, the capacity of the transformer is relatively small. Insulation level: The insulation level of the transformer determines the insulation capability and safety performance of the transformer, and also affects the capacity of the transformer. To sum up, the capacity of the transformer is related to factors such as input voltage and output voltage, load nature, temperature rise, connection method and insulation level. When selecting a transformer, it is necessary to comprehensively consider various factors according to the actual situation to ensure the normal operation and stability of the transformer.
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.

Oil immersed transformers are the most commonly used equipment mainly because of their simple structure and reliable operation. It has faster heat dissipation, uniform conduction, and better insulation performance than the dry-type transformer.Oil transformers are used in power distribution or electrical substations. Their transformer core and coils are immersed in oil, which cools and insulates. Oil circulates through ducts in the coil and around the coil and core assembly, moved by convection.
Power distribution cabinet transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. It lowers the network voltage of 10(6)kV or 35kV to 230/400V bus voltage used by users. This kind of product is suitable for AC 50(60)Hz, three-phase maximum rated capacity 2500kVA(single-phase maximum rated capacity 833kVA, generally not recommended to use single-phase transformer), can be used in the indoor (outdoor), the capacity of 315kVA and below can be installed on the rod, the ambient temperature is not higher than 40℃, not less than -25℃, The maximum daily average temperature is 30℃, the maximum annual average temperature is 20℃, the relative humidity is not more than 90%(the ambient temperature is 25℃), and the altitude is not more than 1000m.
The transformer core provides a magnetic path to channel flux. The use of highly permeable material (which describes the material’s ability to carry flux), as well as better core construction techniques, helps provide a desirable, low reluctance flux path and confine lines of flux to the core. An electrical distribution cabinet is a part of an electrical system whose task is to distribute electrical energy. It includes distribution, protection, measurement, control and signaling instruments. The electrical distribution box also contains wires, various types of insulation, and support components.

Digital measurement – Digital measurement of transformers or other components can be conducted, and the measurement results can be called and collected from the process layer and station control layer through digital networks, thus monitoring transformers and other equipment.Status visualization – The operation status of transformers can be visualized and observed in the power grid.Smart grid or other related systems can express the status information of transformer self-detection or information interaction.
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.
