Centralized Energy Storage Converter
The Centralized Energy Storage Converter operates at 40.5/0.4kV to 1.14kV and is specifically designed for photovoltaic and wind power applications. The output voltage from solar inverters typically ranges from 0.4 to 0.8kV, while wind turbine output is usually between 0.69 to 1.14kV. This unit steps up the voltage to 35kV through a pre-installed substation, which is then transmitted via 35kV cable lines to 35/110(220)kV substations for grid connection.
This series of pre-installed substations combines step-up transformers, high and low voltage switchgear, auxiliary power transformers, UPS, and automation monitoring systems into a well-structured and compact product.
It is designed for easy installation, short construction cycles, low operating maintenance costs, high structural strength, excellent protection ratings, and strong corrosion resistance, making it suitable for harsh environments such as beaches, grasslands, deserts, and gobi. The product meets national quality standards and fully satisfies the requirements for photovoltaic and wind power plants.
The compact design features oil-immersed transformers closely integrated with both high and low voltage compartments. Its independent high voltage protection unit allows for large capacity, unimpeded by spatial constraints.
