Today we are going to reveal a little secret in the power industry: That is why the core of the transformer is not made of a single piece of silicon steel? Maybe you are curious about the advantages of silicon steel sheets such as low magnetic loss and high magnetic permeability, so why not use the entire sheet?
Don't worry, let's uncover this mystery together!
1. Low magnetic loss, ensuring high-efficiency output
Silicon steel sheet is a specially treated electrical steel, its biggest feature is low magnetic loss. When current passes through, the silicon steel sheets will reduce the loss of magnetic energy, making the transformer more energy efficient and also reducing the heat loss in energy conversion. This is the primary reason why the core of the transformer uses silicon steel sheets.
2. High magnetic permeability provides better magnetic flux conductivity
The high magnetic permeability of silicon steel sheets is another major advantage. Magnetic permeability is an indicator that describes the magnetic permeability of a material. High magnetic permeability means better magnetic flux permeability. By using silicon steel sheets, the transformer can guide electromagnetic energy more effectively and reduce magnetic resistance, thus improving the conduction efficiency of current and making the entire system more stable.
3. Reduce eddy current losses and improve transformer performance
In high-frequency electromagnetic fields, eddy currents are an unavoidable problem. The use of silicon steel sheets can effectively reduce eddy current losses. Eddy current losses will cause the core to heat up and reduce the operating efficiency of the transformer. By cleverly designing the shape and structure of the silicon steel sheets, eddy current losses can be effectively reduced and the performance of the transformer improved.
