The New Energy Box-Type Substation for Photovoltaic Power Generation is mainly used as step-up equipment in photovoltaic power generation systems. It receives power from the grid-connected inverter, increases the voltage through the step-up transformer, and transmits electricity to the grid through 10kV or 35kV output lines.
By integrating high-voltage equipment, transformer, protection components, low-voltage switchgear and auxiliary devices into one prefabricated structure, the product helps simplify the layout of photovoltaic power stations. Its compact design, fully sealed oil tank, outdoor enclosure protection and optional monitoring configuration support stable operation in photovoltaic grid connection applications.
The substation has a compact structure and occupies a small installation area. The external radiator design improves heat dissipation performance and supports stable operation in photovoltaic power generation projects.
The product adopts a new transformer series technology with a rational structure and reliable safety performance. It is suitable for high-voltage/low-voltage prefabricated substation applications in renewable energy power systems.
Transformer oil is used as the insulating medium for the 10kV or 35kV high-voltage components. This helps reduce the required safety distance and supports a more compact equipment layout.
The oil tank adopts a fully sealed structure, isolating the transformer oil from the atmosphere. This greatly reduces oil oxidation and moisture intrusion, helping improve system stability, reliability and safety.
The plate-type radiator is easy to disassemble, making maintenance more convenient.
The enclosure is treated with a special shot-blasting process, providing good corrosion resistance and UV resistance. It can also help resist wind and sand erosion in outdoor installation environments.
The low-voltage side adopts intelligent circuit breakers and molded-case air switches. These components provide high breaking capacity and good protection performance.
The transformer oil tank can be equipped with pressure gauges and temperature gauges with communication interfaces. The load switch can also be equipped with a travel switch, supporting remote monitoring, operation and maintenance of the transformer.
The cabinet adopts a fully sealed design. The protection grade of the high-voltage and low-voltage compartments can reach IP54, while the transformer body can reach IP68.
