The electrical equipment within a substation is divided into primary and secondary equipment. The following is a brief introduction to the main equipment within a substation.
1. Primary Equipment
Primary equipment refers to equipment that directly produces, transmits, distributes, and uses electrical energy. It primarily includes transformers, high-voltage circuit breakers, disconnectors, busbars, lightning arresters, capacitors, reactors, etc.
2. Secondary Equipment
Overview of Main Secondary Equipment in a Substation
Secondary equipment in a substation refers to equipment that measures, monitors, controls, and protects the operating conditions of primary equipment and systems. It primarily consists of relay protection devices, automatic devices, measurement and control devices, metering devices, automation systems, and DC equipment that provides power to the secondary equipment.
