AI Technical Summary
When used outdoors, existing energy storage cabinets have poor protective performance, and are prone to condensation and fine dust adhesion in the electrical compartment, which can lead to electrical insulation creep, easy clogging of filters, and affect equipment operation. In addition, the equipment is easily damaged in high humidity environments.
Liquid chillers are used to cool the energy storage converter PCS compartment and battery pack compartment, and a semiconductor cooler is installed in the electrical compartment. The hot and cold ends are isolated by cabinet doors to form an internal air circulation channel. The semiconductor cooler is used to cool the electrical compartment and prevent dust and water from entering.
The protection level of the energy storage cabinet has been improved to prevent dust and water from entering, ensuring stable operation of the equipment in environments with high humidity, salt spray, conductive dust and corrosive gases, and avoiding damage to electrical components.
