The box transformer consists of a high-voltage compartment, low-voltage compartment, and transformer. The Huashi-style box transformer is mainly used for step-up box transformers in new energy power generation.
Product Structure Features
The box transformer consists of a high-voltage compartment, low-voltage compartment, and transformer. The Huashi-style box transformer is mainly used for step-up box transformers in new energy power generation. The structural difference between this and traditional box transformers is that the transformer is placed outside the box body, effectively addressing the issue of quickly dissipating the heat generated by the transformer body through natural climate conditions. The transformer is tightly connected to the box body via side out-lines, and the box body is divided into high-voltage and low-voltage compartments by an internal partition. This makes it an ideal product for new energy power generation.
The high-voltage side of the Huashi box transformer can use a vacuum circuit breaker or a load switch + fuse (combination electrical device). The feature of the combination electrical device is that when any phase fuse blows, the load switch will trip and cut off the power. The main switch can only be closed after replacing the fuse.
The vacuum circuit breaker or load switch + fuse (combination electrical device) on the high-voltage side is mechanically interlocked to prevent misoperation. Both devices are equipped with signal transmission for remote monitoring and control of operational status.
Protection Level
Since the operating environment of this product is relatively harsh, it requires high standards for wind-sand protection, thermal insulation, and heat dissipation. The protection level must meet operational requirements to effectively protect the internal components of the box transformer and extend their service life.
The transformer body has a protection level of IP68, and the outer shell of the box transformer has a protection level of no less than IP54.
