I. Overview

New energy integrated photovoltaic prefabricated cabin, European style all-in-one machine. The layout of the European all-in-one machine is similar to that of a conventional European transformer. The entire machine is made of a container shell, which includes a transformer room, a high-voltage room, a communication power cabinet room, and an inverter room. The rooms are separated by partitions or corrugated boards, and the inverter and high and low voltage rooms are distributed on both sides of the transformer room, forming a grid shaped structure as a whole. The inverter is arranged in a mirror configuration, with lower inlet ports set between the inverter aisles. The side of the inverter is connected to the low-voltage bushing on one side of the transformer through copper bars and flexible connections. The conventional transformer adopts dry-type transformer, matched with vacuum load switch and fuse combination device. The vacuum load switch and fuse combination device is connected to the transformer room through high-voltage cable, and the communication power cabinet is similar to the American integrated machine. The heat dissipation method of transformers usually adopts natural air cooling or forced air cooling.

The container shell is equipped with ventilation louvers, fan outlets, and fans for the internal and external air circulation of the entire box transformer. The inverter room is equipped with fire emergency lights, fire detectors, explosion-proof lighting, and fire extinguishers.

II. Normal environmental conditions for use

1. Altitude: ≤ 3000 meters;

2. Surrounding ambient temperature: -45 ° C~+45 ° C;

3. Environmental humidity: The daily average relative humidity should not exceed 60%, and the monthly average should not exceed 90%. There is no risk of fire, explosion, chemical corrosion, or severe vibration in the environment

III. Product Features

1. Highly integrated: pioneering one-stop solution for DC input, inverter, and boost output; Unified installation and debugging in the factory, overall lifting on site, one-stop completion of transportation, installation, and maintenance.

2. Strong adaptability: Comprehensive consideration of ventilation and heat dissipation, wind and sand resistance, rain and snow resistance, corrosion resistance, low temperature resistance and other requirements.

3. Stable performance: high integration, few fault points, and improved performance stability; Overload of 20%~50% can ensure stable operation (vegetable oil type).

4. High profitability: Reduce investment in AC cables and focus on optimizing electrical equipment such as circuit breakers, lightning protection, power supply, and monitoring; Small footprint and low construction difficulty.

5. Can replace the traditional "MW room+photovoltaic box transformer" mode.
