Industrial Electrical Substation Type Transformer for Electrical Grid Systems
Product Description
Box-type substations are often used in urban areas where space is limited, such as residential neighborhoods, commercial districts, and industrial parks. They can be installed above ground or underground, depending on the site conditions and user requirements.
The high-voltage side of a box-type substation typically includes a transformer, a high-voltage load switch, a high-voltage fuse, and surge arresters. The low-voltage side includes a low-voltage switchgear, energy metering equipment, and reactive power compensation devices.
The transformer in a box-type substation is responsible for stepping down the high-voltage power from the grid to a lower voltage level that can be used by consumers. The transformer core and windings are usually housed in a separate compartment at the rear of the substation, which is designed for better heat dissipation and reduced noise.
The high-voltage load switch is used to connect or disconnect the transformer from the grid, while the high-voltage fuse is designed to protect the substation from overcurrent and short-circuit faults. Surge arresters are used to protect the substation from lightning and other transient overvoltages.
The low-voltage switchgear in a box-type substation is responsible for distributing the power to individual consumers and controlling the flow of electricity. Energy metering equipment is used to measure the power consumption of each consumer, while reactive power compensation devices are used to improve power factor and reduce energy losses.
Box-type substations are designed to be safe and reliable, with features such as insulation, grounding, and protective devices to prevent electric shock, fire, and other hazards. Regular maintenance and inspection are also necessary to ensure that the substation is in good condition and operating as intended.
In addition to shading and ventilation, other measures that can be taken to ensure proper ventilation and cooling of box-type substations include using heat-resistant materials, installing temperature sensors, and using remote monitoring and control systems to detect and respond to potential issues.

Material
1.The cabinet door adopts a double beveled edge process, which increases the structural strength of the same material by 50%.
2.The installation holes are all made using a multi-layer stamping and stretching process, which reduces the sliding wire situation by more than 80%.
3.The inlet and outlet holes adopt a composite structure of knockdown holes and square holes, which can be flexibly selected during on-site installation.
4.The box adopts a double folding process, which increases the structural strength of the same material by 50%.
5.The control circuit adopts a composite design of debugging mode and fire protection mode, greatly reducing the burning of fan and water pump equipment designed for fire protection during debugging.
