Prefabricated warehouse substations The primary and secondary prefabricated cabinets play a significant role in modern electrical power systems. Functionally, they are designed to integrate and house a variety of electrical equipment and components. For the primary side, it typically includes devices such as transformers, circuit breakers, and disconnectors that are crucial for the initial step of power transformation and distribution. These components in the prefabricated cabinet help in stepping up or down the voltage as per the requirements of the power grid, and safely disconnect or connect the power source when needed. On the secondary side, it contains equipment like measuring instruments, control relays, and communication devices. This allows for accurate monitoring and control of the power flow. The measuring instruments can measure parameters such as voltage, current, and power, providing valuable data for system operation and analysis. The control relays can be used to automate certain operations and respond to different electrical conditions, enhancing the reliability and efficiency of the power system. The prefabricated cabinets also offer several advantages. They are pre-assembled in a factory-controlled environment, ensuring high quality and consistency. This reduces on-site installation time and complexity. Moreover, their compact design and modular structure make them easy to transport and install, especially in areas where space is limited or access is difficult. Overall, the primary and secondary prefabricated cabinets are essential for the efficient and reliable operation of electrical power systems, from power generation to distribution and utilization.The difference between equipment prefabricated compartments and traditional substations
