Product application: The new energy box-type transformer is an integrated power distribution equipment specially designed for new energy scenarios such as photovoltaic power generation, wind power generation and energy storage system. Through the integrated structure of "high voltage access-transformer-low voltage distribution", it solves the connection problem of "power generation side-grid side" of new energy power generation, and is one of the core equipment of new energy power station, microgrid and distributed energy system.
Core design and technical features: The new energy box transformer focuses on the demand for "high penetration, volatility and outdoor environment" of new energy power generation, and takes "strong adaptability, safety and reliability, intelligence and high efficiency" as its core advantages.
Integrated structure and efficient deployment: the three-cabin modular design of "high-voltage chamber + transformer chamber + low-voltage chamber" is adopted, all equipment is integrated in the closed box, the factory prefabrication is completed, the site only needs foundation construction and wiring, and the construction period is shortened by 70% compared with the traditional scheme, which is especially suitable for new energy stations with complex construction conditions such as remote areas, mountains and deserts.
Electrical parameters:
Voltage class: support 10kV/35kV (mainstream) or customized (e.g. 66kV offshore wind power scenario) on the high voltage side; 0.4kV/0.69kV on the low voltage side (adapt to inverter output or energy storage system)
Capacity range: 50 kVA to 2500 kVA (standard), expandable to 5000 kVA (large PV/wind projects)
Strong anti-disturbance capability: in view of the harmonic and voltage fluctuation characteristics of new energy generation, optimize the winding design (such as using amorphous alloy iron core to reduce no-load loss), suppress harmonic distortion rate (≤ 3%), and ensure the stability of grid-connected voltage
Outstanding protection and environmental adaptability:
Protection grade: The cabinet is made of stainless steel or aluminum alloy, with protection grade up to IP54 (can be upgraded to IP65). It is dustproof, waterproof and anti-salt fog, and is suitable for harsh environments such as plateau (≤ 4000m), coastal (salt fog) and desert (high temperature).
Heat dissipation design: Natural oil circulation radiator (ONAN) or optional air cooling device (ONAF) is equipped as standard, which can cope with the extreme temperature of -40 ℃ ~ + 50 ℃ to ensure stable operation under full load.
Typical application scenarios:
Photovoltaic power station: connect the photovoltaic string inverter and the booster station to realize high-voltage grid connection after DC to AC;
Wind farm: adapt to the box transformer in the wind turbine tower (such as 35kV collector line box transformer), and collect the electric energy to the booster station;
Energy storage system: used as the interface between the energy storage converter (PCS) and the power grid to realize "charging and discharging" bidirectional transformation;
