Product Overview
The primary and secondary photovoltaic prefabricated cabin launched by Changsong Electric Co., Ltd. is an advanced power equipment solution specifically designed for the construction of intelligent substations. This prefabricated cabin adopts a prefabricated cabinet structure, comprising a main cabinet and a secondary cabinet, integrating key equipment and components in modern power systems. The main cabinet is typically equipped with core devices such as transformers, circuit breakers, and disconnect switches, responsible for power conversion and primary distribution; whereas the secondary cabinet contains measuring instruments, control relays, communication equipment, etc., enabling precise monitoring and control of power flow. The primary and secondary photovoltaic prefabricated cabin not only embodies the application of new technologies, materials, and equipment but also significantly shortens the construction period, enhances project quality, reduces overall costs, and benefits environmental protection through highly integrated and modular design.
Main product features
Highly integrated and modular design
The primary and secondary photovoltaic prefabricated cabin adopts a highly integrated and modular design concept, integrating complex power system equipment into a compact prefabricated cabin body. This design not only facilitates transportation and installation but also significantly reduces the workload and complexity of on-site construction. The modular structure enables flexible combination and expansion of the prefabricated cabin according to actual needs, meeting the construction requirements of intelligent substations of different scales and configurations.
All-metal cabin with high protection grade
The prefabricated cabin adopts a fully metallic cabin design, featuring excellent structural strength and resistance to environmental erosion. With an IP54 protection rating, it ensures that the internal equipment remains dry and clean in harsh environments, effectively preventing the impact of harmful factors such as windblown sand and condensation on the equipment. Additionally, the metallic cabin provides good electromagnetic shielding, ensuring the stable operation of the equipment inside.
Well-established HVAC system
To cope with extreme climatic conditions, primary and secondary photovoltaic prefabricated cabins are equipped with a comprehensive HVAC system. This system can automatically adjust the indoor temperature based on the ambient temperature to ensure that the equipment operates in a suitable working environment. Meanwhile, the air conditioning system also features dehumidification to effectively prevent damage to the indoor equipment caused by moisture.
Intelligent Monitoring and Control System
The prefabricated cabin integrates an advanced intelligent monitoring and control system capable of real-time monitoring of equipment operating status and parameters, such as voltage, current, and power. Through data analysis and processing, the system can promptly identify potential faults and issue early warnings, providing strong decision-making support for operation and maintenance personnel. Additionally, the intelligent control system supports remote operation and automated control, enhancing the reliability and efficiency of the power system.
Energy conservation, environmental protection, and sustainable development
The design and manufacturing of primary and secondary photovoltaic prefabricated cabins fully take into account the requirements of energy conservation, environmental protection, and sustainable development. By optimizing equipment selection and layout, energy consumption and carbon emissions are reduced. Meanwhile, the modular design of the prefabricated cabins enables easy disassembly and recycling of equipment after its end-of-life, thereby reducing environmental pollution.
