Definition and Function of 1. Box Transformer
Box substation is a kind of equipment in the power system, installed on the transmission line, used to convert high-voltage electricity into low-voltage electricity, and cooperate with the power distribution system to supply electricity to the place where it is needed. Although American and European box transformer are transformers, there are many differences.
2. different appearance design
American box variable models are generally marked with English letters and numbers, and the appearance shape is mainly square or rectangular. The edges of the box are covered with thick copper plates, which are thicker than European box changes. European-style box is mainly marked with numbers and letters, and its appearance is diversified, including rectangular, circular, oval and so on. The box body is made of steel plate, which is lighter than the American box change.
3. different installation methods
The installation mode of American box transformer is generally hanging type and pillar type, and some large-capacity box transformer is buried. European box change is mainly installed in the underground enclosed box, this model is also known as the underground box change. The structure of American box transformer is relatively simple and easy to maintain, while the installation environment of European box transformer is complex and the maintenance is difficult, but it can protect the box transformer well.
Different 4. power supply wiring
The power supply wiring of American box transformer is generally directly connected to the main transformer, and can also be wired through branch lines. European-style box transformer power wiring is usually achieved through the switch operation, making the switch has a more powerful control capability.
Differences in 5. performance
American box variable capacity is generally small, suitable for some small power system, but the output voltage is more stable, high efficiency, low noise. European box transformer is suitable for large-scale power system, with good protection function and environmental adaptability, strong anti-short circuit ability, safe operation, but the efficiency is slightly lower.
