In modern power systems, safe, stable and efficient operation is an eternal pursuit. As the core component of power infrastructure, the electrical equipment system is like the "bones" and "nerves" of the human body, both indispensable. With 40 years of experience in the electrical field, People's Electrical Appliances Group has always promoted industrial progress with professional strength. Today, we will deeply analyze the synergistic effect of primary and secondary electrical equipment to help you fully grasp the essence of power system operation.
Primary Electrical Equipment: The "Backbone" of Power Transmission
Primary electrical equipment directly participates in the generation, transmission and distribution of electrical energy, serving as the "physical framework" of the power system. Its core feature is handling high voltage and large current, undertaking the important task of power conversion and transmission.
Typical Equipment Includes:
Circuit Breaker: Quickly cuts off current in case of faults to ensure system safety;
Transformer: Realizes voltage level conversion and optimizes power transmission efficiency;
Isolating Switch and Busbar: Constructs stable power circuits to ensure reliable connection between equipment;
Instrument Transformer: Accurately measures current and voltage, providing a data foundation for system monitoring.
Secondary Electrical Equipment: The "Intelligent Hub" of System Operation
Secondary electrical equipment focuses on the control, protection and monitoring of primary equipment, acting as the "neural network" of the power system. Its core value lies in realizing precise regulation of primary equipment through automated and intelligent means.
Typical Equipment Includes:
Relay Protection Device: Real-time analyzes fault signals and triggers protection actions in milliseconds;
Measuring Instruments and Monitoring System: Dynamically collects voltage and current data to support intelligent decision-making;
Automatic Control System: Implements remote operation and fault self-healing to improve operation and maintenance efficiency;
Communication and Data Processing Unit: Ensures efficient information flow and supports digital management.
