The casing of a box type substation is an important component that not only protects internal equipment from external environmental influences, but also has certain aesthetic and environmental adaptability. Here are some detailed information about the casing of the transformer box: Classification of Box Transformer Shell: The box shell of a box type substation is divided into 10, 20, and 30 levels, which means that the temperature rise of the transformer inside the shell exceeds the difference between the temperature rise measured outside the shell of the same transformer, such as 10K, 20K, and 30K. Material type: Non metallic landscape box type transformer shell: Generally made of high-strength cement concrete as the raw material for the shell, it has the characteristics of strong plasticity and long service life. Composite panel box transformer shell: The surface is made of various composite panel materials such as PVC, high-strength alloy, galvanized, and aluminum zinc coated sheet. It is lightweight and highly corrosion-resistant, but may undergo chemical reactions over time leading to embrittlement. Carved board box transformer shell: The exterior is a high-quality color embossed decorative metal plate treated with a special layer, with a flame-retardant polyurethane insulation layer added in the middle. The base layer is an aluminum foil insulation layer, with a beautiful and atmospheric style. Metal box transformer shell: It is mostly made of high-strength and corrosion-resistant metals such as galvanized sheet and stainless steel sheet, which have high structural strength and good heat dissipation performance. However, the insulation effect is poor and not suitable for humid and rainy areas. Other new types of transformer housings: such as the use of DMC insulation material sheets for automotive bumper materials for transformer housings, with structural safety and insulation protection; A new type of non-metallic box transformer shell made of glass cement material; Use brightly colored steel plate composite box transformer shells for insulation and heat preservation. Design philosophy: The design of the casing of the transformer box should take into account practicality, aesthetics, and environmental adaptability, considering factors such as climate conditions, geographical features, electromagnetic interference, etc., to ensure effective resistance to harsh environments while integrating with the urban landscape. Manufacturing process: With the development of intelligent manufacturing technology, the production of transformer housings is gradually transitioning towards automation and intelligence, improving production efficiency and accuracy. Quality control: Strict quality control measures are required at every stage, from raw material procurement, production process to finished product inspection, to ensure that the products meet national standards and customer requirements. Anti corrosion technology: Made of stainless steel material and treated with corrosion-resistant powder coating process, effectively preventing rust and extending product service life. In summary, the selection and design of the casing for the transformer box need to consider multiple factors to ensure its functionality, aesthetics, and durability.
