Description

Wind Box-Type Substation product Overview

This American-style pad-mounted transformer (combined transformer) is a dedicated Wind Box-Type Substation and high-performance Box Type Prefabricated Substation, widely deployed in wind farms and solar power plants. The Wind Box-Type Substation integrates step-up transformer core, switchgear, fuses, tap changers and supporting auxiliary equipment into a single unit; its high-voltage switches and fuses are enclosed in the oil tank, eliminating the need for an independent transformer enclosure. This integrated design makes the Box Type Prefabricated Substation feature a compact footprint and excellent heat dissipation performance, perfectly matching the power conversion and distribution needs of new energy power generation scenarios such as wind and photovoltaic power.

Wind Box-Type Substation product Features

Optimized Structural Layout：The Wind Box-Type Substation adopts mesh-style or triple-unit layout, clearly divided into high-voltage compartment, low-voltage compartment and transformer unit three dedicated sections. This zoning design rationalizes the internal structure of the Box Type Prefabricated Substation, ensuring independent and safe operation of each functional module and facilitating on-site operation and maintenance.
Enhanced High-Voltage Compartment Safety：The high-voltage compartment door of the Wind Box-Type Substation is equipped with an observation window and electrical interlock system, which greatly improves operational safety and real-time visibility of equipment status, and further elevates the safety protection level of the Box Type Prefabricated Substation in outdoor wind farm scenarios.
Standardized Low-Voltage Compartment Configuration：The low-voltage compartment of the Wind Box-Type Substation is fitted with GGD-type AC low-voltage switchgear, designed with layered and functionally segmented compartments. This design ensures clear wiring and convenient maintenance for the Box Type Prefabricated Substation, effectively improving the operational stability and maintenance efficiency of the low-voltage side circuit.
Integrated Oil Tank Transformer Design：The Wind Box-Type Substation houses transformer core, high-voltage load switch and protective fuses in a shared oil-filled iron tank, which minimizes the overall volume of the equipment while ensuring reliable insulation and stable operation. This integrated structural design is the core advantage of the Box Type Prefabricated Substation, making it more adaptable to the space-limited installation conditions of wind farms.
Wide Optional Capacity Range：The Wind Box-Type Substation offers optional capacities from 1600 kVA to 4000 kVA, which can flexibly match the diverse power requirements of different-scale wind farm and solar power plant projects. The wide capacity coverage makes the Box Type Prefabricated Substation a versatile power equipment for new energy power generation scenarios, with strong project adaptability.

Wind Box-Type Substation Adaptive Working Scenarios

Onshore Wind Farm Environments：The Wind Box-Type Substation is highly adaptable to open-air, high-wind (≤60m/s) onshore areas with large temperature variations (-40℃ to 55℃), and is resistant to dust, sand and general outdoor corrosion. This environmental adaptability makes the Box Type Prefabricated Substation the ideal power equipment for grassland, hilly and other onshore wind farm sites.
Coastal/Offshore Wind Farm Environments：The Wind Box-Type Substation is designed with enhanced anti-salt-spray coating and sealed enclosure, which can withstand high humidity, salt-laden air and marine atmospheric corrosion. The corrosion-resistant design enables the Box Type Prefabricated Substation to operate stably in offshore platforms and coastal wind farm zones within 5km of the coastline.
High-Altitude Wind Farm Environments：Optimized for high-altitude areas (≤3000m above sea level), the Wind Box-Type Substation has upgraded insulation performance to adapt to low-air-pressure plateau conditions. This optimization ensures the Box Type Prefabricated Substation maintains stable and reliable operation in plateau wind power projects with harsh natural conditions.
Grid-Connected Supporting Scenarios：The Wind Box-Type Substation is suitable for outdoor power distribution areas adjacent to wind turbine clusters, perfectly matching the outdoor installation requirements of wind farm booster stations and power collection lines. The compact structure of the Box Type Prefabricated Substation allows flexible layout in wind farm power collection systems, improving the efficiency of wind power grid connection.
Low-Attendance Operation Sites：Tailored for unattended or remote monitoring scenarios, the Wind Box-Type Substation features high operational stability and low maintenance demand, adapting to environments with limited on-site maintenance resources. Its reliable performance aligns with the decentralized layout of wind farms, enabling the Box Type Prefabricated Substation to realize long-term unattended stable operation.
