Brand: WEIJI
USES: The European integrated energy storage, current conversion and boosting device effectively solves the instability and periodicity problems of wind energy and photovoltaic energy.
The European-style integrated energy storage converter and booster integrates an energy storage converter, busbar bridge, low-voltage compartment (including communications and power distribution), dry-type transformer, high-voltage compartment (equipped with a vacuum load switch or circuit breaker), and protective enclosure. It is primarily used to store green power, such as solar and wind power, and when needed, converts it into AC power via a power storage converter (PCS). The power is then boosted by a three-phase dry-type booster transformer for output, effectively addressing the instability and cyclical nature of wind and photovoltaic energy.
1. Highly integrated, space-saving. The compact size and high integration significantly reduce on-site infrastructure work and floor space, shortening construction cycles and accelerating power supply commissioning.
2. The cabinet is factory-fabricated, commissioned, and fully assembled. On-site docking and connection are required, reducing construction complexity, simplifying equipment maintenance, and enabling unmanned operation.
3. Safe operation and maintenance-free design. The internal dry-type transformers offer strong fire retardancy, stable operation, and require no routine maintenance, meeting high fire protection requirements. The high-voltage unit is equipped with a vacuum load switch or circuit breaker, supporting remote monitoring and comprehensive protection.
4. Strong environmental adaptability. The enclosure undergoes special anti-corrosion and UV treatment, offering excellent resistance to rust, sun exposure, and wind and sand erosion, making it suitable for a variety of harsh outdoor environments.
