Photovoltaic Booster Box Transformer — Product Overview
In the current widespread promotion and application of new energy photovoltaic power generation, photovoltaic step-up transformer is one of the important equipment in the photovoltaic power generation system. Photovoltaic power generation dedicated box transformer, abbreviated as photovoltaic box transformer, is a high-voltage/low-voltage prefabricated substation that integrates high-voltage switchgear, transformer body, and protective fuses in the oil tank, with low-voltage switchgear and corresponding auxiliary supporting equipment.

Product Details
Photovoltaic box transformer is a specialized distribution facility that boosts the voltage of 0.27kV or 0.315kV from photovoltaic grid connected inverters to 10kV or 35kV through a step-up transformer, and outputs electrical energy upward through 10kV or 35kV lines. It is an ideal supporting equipment for photovoltaic power generation systems.
The size of the box type substation for photovoltaic power generation and the number of internal switch cabinets are related to the voltage that needs to be stepped up. The higher the voltage level, the more cabinets inside the box. Generally, the final decision can be made based on the design drawings provided by the design institute.
Compared with conventional substations with the same capacity and load, 10kV photovoltaic box type substations occupy less land, reduce investment by about 40% to 50%, and save more than 100000 to 200000 yuan. The container is equipped with intelligent measurement and control terminals to achieve remote intelligent control of the substation.
