Transformers are mainly composed of iron cores and windings. The iron core is the magnetic circuit channel of the transformer, which is mostly oiled on both sides and insulated from each other by painting, and the silicon steel sheet with a thickness of 0.35 to 0.5mm is stacked.
The winding is the circuit part of the transformer, which is wound by a certain number of turns of gas-wrapped wire. The one connected to the power supply, we call it the primary winding, also known as the primary winding. The one connected to the load is called the secondary winding, also known as the secondary winding, or the secondary winding.
The basic form of the core structure is the core type and the shell type, and the core column of the transformer with the heart structure is surrounded by
windings. To put it simply, the windings surround the iron core, the structure is relatively simple, and the assembly and insulation are relatively easy, so the
transformer often adopts a heart structure.
