Since silicon steel has the above advantages, why not use the whole silicon steel as the iron core and process it into a sheet? This is because the sheet iron core can reduce another iron loss – “eddy current loss”. When the transformer works, there is alternating current in the coil, and the magnetic flux generated by it is of course alternating. This changing magnetic flux produces an induced current in the iron core. The induced current generated in the iron core flows in a ring in a plane perpendicular to the magnetic flux direction, so it is called eddy current. Eddy current losses also heat the core. In order to reduce the eddy current loss, the iron core of the transformer is stacked with silicon steel sheets insulated from each other, so that the eddy current passes through a small section in the narrow and long circuit, so as to increase the resistance on the eddy current path; At the same time, the silicon in silicon steel increases the resistivity of the material and reduces the eddy current.
The common mode inductor using nanocrystalline core material can well suppress the peak voltage, protect sensitive components, and reduce the motor shaft voltage. Because of the unique characteristics of nanocrystalline core, it has been well used in some high-power system industries. Electric energy meter, power meter, ammeter, electric measuring equipment and other instrument fields. Various power current transformers in power transmission and distribution monitoring system. Leakage protection, relay protection, servo motor protection, fire monitoring, etc Current and voltage data sampling, etc.
Silicon steel is a traditional magnetic material mainly for 50Hz to 1000Hz electronic and electrical applications. The toroidal core is one of the main products of Transmart Industrial. Our silicon steel core series has many styles to meet the diversified needs of customers. We manufacture various type of cores in silicon steels, such as Current Sensor Cores, silicon steel transformer core, Instrument Transformer Cores, Torodal cores, C-cores, Unicore etc. Transmart Industrial carries out strict quality monitoring and cost control on each production link of toroidal core, from raw material purchase, production and processing and finished product delivery to packaging and transportation. This effectively ensures the product has better quality and more favorable price than other products in the industry. Discover additional details on transmart.net.
Now, the test of magnetic core material loss of power frequency power transformer is carried out under sine wave voltage with distortion less than 2%. The actual power frequency power grid distortion is 5%. In this case, the loss of iron-based amorphous alloy increases to 106% and that of silicon steel increases to 123%. If the high-order harmonic is large and the distortion is 75% (such as power frequency rectifier transformer), the loss of iron-based amorphous alloy increases to 160% and the loss of silicon steel increases to more than 300%.
On the one hand, it can isolate eddy current, and the data is suitable for higher frequencies; On the other hand, due to the gap effect between particles, the data has low permeability and constant permeability; Because the particle size is small, there is basically no skin phenomenon, and the change of permeability with frequency is relatively stable; Moreover, the powder core can be prepared into special-shaped parts of various shapes for different fields; Finally, the damaged strip in industry can be crushed into magnetic powder, and then made into magnetic powder core, which can reduce the loss and improve the use value of data. The magnetoelectric properties of magnetic particle core mainly depend on the permeability of powder material, size and shape of powder, filling coefficient, content of insulating medium, forming pressure and heat treatment process.
