It is a prefabricated type that integrates converter (can be independent), step-up transformer (oil, dry, amorphous, silicon steel), high-voltage current-limiting fuse, load switch, low-voltage switchgear, intelligent control device and corresponding auxiliary equipment In the grid-connected system, the electrical connection between each unit is completed in the box transformer, and only the high-voltage cable and the incoming cable of the converter need to be connected on site.
Transformation, protection and control of power generation and energy storage systems such as wind energy and solar energy, voltage transformation, protection and control of terminal power systems such as industrial enterprises, residential buildings, and infrastructure, and transformation of (N) new energy vehicle charging stations pressure, protection and control.
Small size, easy installation, convenient transportation, high cost performance;
High mechanical strength and rigidity, meeting the requirements of lifting, transportation and installation;
With reasonable protective structure, dust-proof structure and low temperature resistance, anti-exposure, anti-corrosion, anti-wind and sand, anti-rainwater;
The electrical connection between each unit is completed in the box transformer, and only the high-voltage cable and the incoming cable of the converter need to be connected on site;
Natural ventilation or automatic control of forced cooling and exhaust design can effectively control and reduce the temperature inside the box to meet the requirements of full-load operation;
Intelligent control has strong adaptability, built-in protection devices such as smog, over-temperature, and current, and comprehensively manages the running status of inverter, energy storage, and boost in real time;
