Summary

Container-type substations are mainly used in large and medium-sized photovoltaic power stations. Outdoor standard container house design is adopted, and the grid-connected inverter, monitoring power distribution cabinet, monitoring unit, installation system and fire protection are highly integrated and designed to meet the needs of large scale photovoltaic power plants. , The modular design and rapid installation of medium-sized photovoltaic power stations ensure the long-term, reliable and safe parallel power generation of photovoltaic power stations.

Product Description

Product Feature

Photovoltaic power plants have different application environments. Under the premise of satisfying heat dissipation and ventilation, the inverter room needs to have good dustproof, waterproof and anti-corrosion capabilities. The container-type inverter house combines the functions of heat dissipation and protection with inverter products, and provides the owner with a personalized internal space, forming a photovoltaic system access solution platform with integrated functional design.

The container-type inverter room integrates the inverter and the DC cabinet, and adopts a direct exhaust air duct. The air duct does not contain a fan, which is zero loss and maintenance-free.. When the inverter is working, most of the heat is discharged out of the container through the air duct, and part of the heat is also transferred to the inside of the box through radiation. The internal air absorbs the heat and flows to the top, and then is discharged by the exhaust fan on the top of the container to ensure the inverter Long-term reliable operation. Blinds are added on the side of the container, and the external cold air directly enters the box through the side window and continuously flows on the back of the inverter. The heat dissipation method on the back of the inverter changes from natural convection heat transfer to forced convection and convective heat transfer. The coefficient has been increased by nearly 10 times, which greatly improves the heat exchange capacity of the back and reduces the surface temperature; not only that, the continuous cold air forms a low temperature layer around the inverter, which provides a good working environment for the inverter.

An insulation layer is added around the container body, and rock wool with low thermal conductivity is used as the insulation material to effectively isolate solar radiation. The S-shaped shutters of the air inlet of the box adopt a patented design, which can effectively prevent the intrusion of sand and rain. The dustproof cotton adopts a special high-flux low-resistance filter plate, which can be reused. When replacing, just press the blind button of the shutter to take out the Dust cotton, the entire operation process takes less than a few seconds. Sungrow's containerized inverters have built-in 500KW inverters and DC cabinets, which are placed symmetrically on the center line, which is convenient for personnel to view equipment information and front maintenance; integrated double doors are designed on both sides of the container to provide fast and convenient maintenance channels. If you need to replace the large components in the inverter, just open the double door on the back.
