A substation is a place in the power system that converts voltage and current, receives and distributes electrical energy. The substation in the power plant is a step-up substation, and its function is to boost the power generated by the generator and feed it to the high-voltage grid.
The electrical equipment in the substation is divided into primary equipment and secondary equipment. The main equipment in the substation is briefly introduced below.
1. Primary equipment
Primary equipment refers to the equipment that directly produces, transmits, distributes and uses electrical energy, mainly including transformers, high-voltage circuit breakers, isolating switches, bus bars, arresters, capacitors, reactors, etc.
2. Secondary equipment
The secondary equipment of the substation refers to the equipment that measures, monitors, controls and protects the operating conditions of the primary equipment and systems. A DC device that supplies power to the secondary device.
The above devices need insulation, oxidation resistance, and high temperature resistance. It is difficult for ordinary magnet wires to meet this requirement. Only enameled wires can achieve the goal well.
