The Huabian photovoltaic grid-connected cabinet is a compact integrated solution designed by domestic engineers, combining the excellent heat dissipation performance of Meibian structures with the comprehensive protection concept of European transformer designs. By optimising the internal layout and enclosure structure, Huabian effectively addresses the common issues of insufficient protection in Meibian designs and poor heat dissipation in traditional European transformer enclosures.
With a balanced design that integrates protection, ventilation, and compactness, Huabian offers strong applicability and promising deployment potential in modern renewable-energy projects.
Huabian is divided into three parts: high-voltage room, low-voltage room, and transformer, arranged in an "L" or "V"shape
Huabian transformers can only use oil immersed transformers and cannot use dry-type transformers
The transformer body and heat dissipation fins of Huabian are both open and exposed outside the box, with good heat dissipation effect. All other live compartments are sealed in independent compartments, and each compartment is separated into independent compartments by partitions. A lower manhole is also provided inside the box for easy installation and maintenance
The box body is made of cold-rolled steel plate or stainless steel plate, with smooth inner and outer surfaces, no rust, coating peeling or collision damage, a firm and uniform coating layer, and no obvious contrast reflection
The top cover of the box is equipped with a rainproof sealing cover and a rainproof eave, and the double-layer structure of the box top cover can prevent thermal radiation
