New Energy Box-Type Substation (Wind Power)

Product Description

This New Energy Box-Type Substation (Wind Power) is a high-voltage/low-voltage prefabricated substation specifically designed for wind power and other new energy generation systems. It integrates high-voltage switchgear, transformer body, and protective fuses (housed in an oil tank) with low-voltage switchgear and corresponding auxiliary equipment into a single unit.

Its core function is to boost the voltage from new energy grid-connected inverters or alternators to 10kV or 35kV via a step-up transformer, then transmit the electrical energy to the power grid through 10kV or 35kV lines. With its high integration, reliability, and adaptability to harsh outdoor environments, it serves as an ideal supporting device for wind power projects, ensuring efficient and stable grid connection of renewable energy.

Key Features

• Compact Structure & Efficient Heat Dissipation: Boasts a space-saving compact design with external radiators, which significantly enhances heat dissipation efficiency. This ensures the transformer operates within a stable temperature range even under high-load wind power generation conditions.

• Advanced Transformer Technology: Adopts new-generation transformer series technology with a rational internal structure. This design improves operational safety and reliability, minimizing the risk of equipment failure in long-term wind farm operations.

• Transformer Oil for HV Insulation: Uses transformer oil as the insulating medium for 10kV or 35kV high-voltage (HV) components. This greatly reduces the required safety distance for HV elements, further optimizing the overall size of the substation.

• Fully Sealed Oil Tank: The oil tank features a fully sealed structure that completely isolates transformer oil from the atmosphere. This design reduces oil oxidation and prevents moisture intrusion, significantly improving the system's stability, reliability, and service life. Additionally, it is equipped with chip radiators that are easy to disassemble and maintain.

• Anti-Corrosion & Weather-Resistant Enclosure: The substation enclosure undergoes a special shot blasting process, providing excellent anti-corrosion, anti-exposure (UV-resistant) performance, and effective resistance to sand erosion--ideal for the outdoor, harsh environments of wind farms.

• High-Performance Low-Voltage (LV) Switches: The LV side is equipped with China's latest intelligent circuit breakers and molded-case air switches. These components offer high breaking capacity and superior protection performance, effectively safeguarding the LV circuit against overcurrent, overload, and short circuits.

• Remote Monitoring & O&M Capability: The transformer oil tank can be equipped with pressure gauges and thermometers with communication interfaces, while the load switch can be fitted with a travel switch. These configurations enable remote monitoring, operation, and maintenance of the substation, reducing the need for on-site manual intervention.

• Superior Protection Ratings: The substation adopts a fully sealed design, with the HV/LV chamber achieving IP54 protection rating (dust protection: Class 5; water protection: Class 4) and the transformer body reaching IP68 protection rating (dust protection: Class 6; water protection: Class 8), ensuring durability in complex outdoor conditions.

Technical Specifications

Application Scenarios 

• Onshore Wind Farms: As a dedicated step-up device for onshore wind turbines, the substation adapts to outdoor wind speeds up to 35m/s and resists sand erosion via its shot-blasted enclosure. Its fully sealed oil tank and IP68-rated transformer body ensure stable operation in variable temperature environments (-40℃ ~ +45℃), making it suitable for large-scale onshore wind power grid connection.

• Plateau Wind Power Projects: With an altitude adaptation capacity of up to 4500m (plateau-type design for altitudes > 2000m), the substation addresses the challenges of low air pressure and extreme cold on plateaus. It effectively boosts the voltage of plateau wind turbines to 10kV/35kV for grid connection, supporting clean energy development in high-altitude regions (e.g., Qinghai, Tibet in China).

• Coastal Wind Farms: The substation's special shot blasting process provides strong anti-corrosion performance, resisting salt spray erosion in coastal environments. Its fully sealed oil tank prevents moisture intrusion caused by high coastal humidity, ensuring long-term reliable operation. It is ideal supporting equipment for coastal wind power projects.

• Wind-Solar Hybrid Power Stations: In wind-solar hybrid systems, the substation serves as a unified step-up and grid-connection device. It boosts the voltage from both wind turbines and PV inverters to 10kV/35kV, realizing integrated grid connection. Its remote monitoring function also simplifies the unified operation and maintenance of the hybrid power station, improving energy utilization efficiency.
