The prefabricated cabin is composed of a cabin, a secondary equipment screen cabinet (or rack), a high-pressure cabinet, and auxiliary facilities of the cabin.

The prefabricated cabin is composed of a cabin, a secondary equipment screen cabinet (or rack), a high-pressure cabinet, and auxiliary facilities of the cabin., Complete the production, assembly, wiring, commissioning and other work in the factory, and transport it to the project site as a whole.On the basis of equipment, the equipment is integrated by the manufacturer, factory processing is completed, on-site secondary wiring is reduced, design, construction, commissioning and workload are reduced, and maintenance is simplified.

 The equipment has the technical characteristics of standardization, modularity and prefabrication.The metal structure of the cabin has three layers, and each layer has the effect of thermal insulation and cold resistance to the prefabricated cabin.Choose refrigerator insulation measures and processes.The materials are made of double-layer high-quality steel and environmentally friendly metal decorative layers to improve cold resistance.Polyurethane filling is filled with polyurethane inside, which has a certain flame retardant and heat preservation effect.

 In order to ensure that the thermal insulation and cold resistance requirements of the prefabricated cabin meet the standards, the cabin should be equipped with an automatic temperature control system to monitor the temperature in the cabin in real time, and equipped with heating equipment, which is activated when the temperature is lower than the standard requirements to improve the temperature in the cabin.Note that the heating equipment should be of industrial type and have the ability to heat for a long time to ensure that the operating environment in the cabin is relatively stable.If a more reliable operating environment is required, a micro-positive pressure air conditioning system should be installed in the cabin and more useful heating measures should be adopted.

 According to the different functions of internal equipment, the prefabricated cabin is divided into public equipment cabin, interval equipment cabin, AC and DC power supply prefabricated cabin, battery prefabricated cabin and other modules.According to different voltage levels, different modules can be divided into several sub-modules.

 Prefabrication refers to the structure of the cabin of the prefabricated cabin, the internal equipment and equipment, the connection between the internal equipment, the cables and optical cables between the internal equipment are prefabricated by the factory, and the equipment, wiring and commissioning of all the equipment in the factory are completed. The prefabricated cabin and its internal equipment are transported to the substation site as equipment, and the cables of the prefabricated cabin are grounded and energized in place at the end, which improves the efficiency of on-site construction and completes the goal of reducing the construction cycle of intelligent substations.
