Investigation of the distribution of magnetic induction in the magnetic core of a power transformer when operating under load
The distribution of magnetic induction along the length of the magnetic core of a transformer with concentric windings during operation under load is studied. The magnetic circuit is divided into two zones: with high (the influence of the primary winding) and with low (the influence of the secondary winding) magnetic induction. With the internal arrangement of the primary winding, the zone of high induction value is minimal. To reduce the magnetic losses, it is proposed to provide for a primary winding of the inner concentric, and to increase the cross-section of the magnetic core under it. This will align the magnetic induction along the length of the magnetic core. Mathematical modeling is used to quantify the optimal parameters of the transformer under various conditions.
