Product structure characteristics
·Compact structure and small size, only about 1/3~1/5 of domestic products with the same capacity, which greatly reduces the area occupied;
·Fully sealed, fully insulated structure, no insulation distance, reliable protection of personal safety;
The high voltage adopts load switch and fuse combination electrical protection;
·High-voltage wiring can be used for both ring network and terminal. Flexible power supply mode and high reliability;
·Excellent transformer performance, low loss, low noise; strong overload capacity, strong short-circuit resistance and impact resistance;
·Satisfy various low-voltage feed-out requirements, can be selected according to the plan, or designed by yourself;
·The cable head has two kinds of 200A elbow type cable joint and 600AT type joint. The elbow type cable joint is suitable for the cable cross-sectional area of 35-185m㎡, and the T-type joint is suitable for the cable cross-sectional area of 35-500m㎡.
The material of the cable head is divided into copper core and aluminum core, both of which can be equipped with fully insulated zinc oxide arresters. The 200A elbow cable head can be plugged and unplugged under load, and it can also act as an isolating switch.
Applicable places of American box change
In view of the structural characteristics and advantages and disadvantages of American box substation, American box substation is suitable for the electricity consumption of multi-storey houses and other unimportant buildings with relatively low power supply requirements. According to our actual use situation, after the American box transformer is equipped with a small ring network switch station, it is fully suitable for the power supply needs of multi-storey residential buildings. Because it is the failure of the box substation, the impact on the residents is not large, but it is not suitable for small and high-rise buildings.
The main features of American box change
Strong overload capacity, allowing overload 2 times 2 hours, overload 1.6 times 7 hours without affecting the life of the box change.
The elbow plug connector is very convenient for the connection of high-voltage incoming cables, and can be used as a load switch in emergency situations, which can be plugged and unplugged under power.
Double fuse protection is adopted, and the plug-in fuse (BAY-o-net) is a dual sensitive fuse (temperature, current) to protect the short-circuit fault occurred on the secondary side of the box transformer. The backup current-limiting protection fuse (ELSP) protects the internal faults of the box transformer and is used to protect the high-voltage side.
Transformers generally use high ignition point oil (FR3).
All components such as fuses for high-voltage load switch protection are placed in the same oil tank as the transformer core and windings.
