[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy, and distributes electric energy. The substation in a power plant is a step-up substation, which boosts the electric energy generated by the generator and feeds it into the high-voltage power grid. The core equipment of the substation is the transformer, which is used to convert electric energy from one voltage to another. The transformer realizes the conversion and transmission of electric energy through the iron core and windings.
[0003] The iron core and new winding device inside the box-type substation are the core components of the substation, and together they constitute the basic structure of the transformer. The function of the iron core and new winding device inside the box-type substation is to achieve voltage conversion and power transmission. When current passes through the winding, a magnetic field is generated, and the magnetic energy is transferred to the winding through the magnetic permeability of the iron core, thereby realizing the conversion of electrical energy. By reasonably designing and optimizing the structure of the iron core and winding device, energy loss can be effectively reduced, the efficiency of the transformer can be improved, and the needs of different power systems can be met.
