Zhejiang box transformer manufacturer, non-standard customized European and American transformers

The difference between European and American transformers lies in their composition, high-voltage components, and applications.

1、 Different compositions: American transformers, high-voltage protection consists of plug-in fuses, backup fuses, and load switches; European transformer, high-voltage protection is switched according to the load switching frequency, using compressed air, vacuum, SF6 load switches+fuses; Larger capacity.

2、 The high voltage part is different: American transformers have only two ways of high voltage, ring network (dual power supply) or terminal power supply. And the European transformer adopts an independent high-voltage unit, which can be customized according to user requirements. As each functional unit is independent, each unit (high voltage, transformer, low voltage) can be customized according to user requirements. Due to high voltage limitations, American transformers have a small size and performance that is far less flexible than European transformers. But it is much cheaper than European transformers.

3、 Different applications: American transformers are suitable for multi story residential buildings and other non key buildings with relatively low electricity demand. From the actual usage situation, after the American box transformer is equipped with a small ring network switch station,The power supply requirements for multi story residential buildings. Due to the malfunction of the transformer, the impact on residents is not significant, but it is not suitable for small and high-rise buildings.

Used for the public requirement of a rated AC voltage of 12kV on the primary side, a maximum transformer capacity of 1600kVA, and a working frequency not exceeding 50Hz, suitable for outdoor pre installed substations. The substation is connected externally through cables and can be operated from both inside and outside. Suitable for high-rise buildings, urban and rural buildings, residential areas, high-tech development zones, small and medium-sized factories, mines, oil fields, and temporary construction sites, used in power distribution systems for receiving and distributing electricity.

Characteristics of American Box Transformer

Advantages: Small size, small footprint, easy to place, and easy to coordinate with the environment of the community. It can shorten the length of low-voltage cables, reduce line losses, and also lower the cost of power supply matching.

Disadvantages: Low power supply reliability; Without an electric mechanism, it is impossible to install distribution automation devices; No capacitor device, which is not conducive to reducing line loss; Due to the different civil foundations of box transformers with different capacities, it is inconvenient to increase the capacity of box transformers; When the transformer is overloaded or the user increases capacity, the civil engineering needs to be rebuilt, which will result in a long power outage time and increase the difficulty of the project.

Application: American box type transformer is suitable for the electricity consumption of multi story residential buildings and other unimportant buildings with relatively low power supply requirements. Based on our actual usage, the American style box transformer with a small ring network switch station is suitable for the power supply needs of multi story residential buildings. Because the box type substation has malfunctioned, the impact on residents is not significant, but it is not suitable for small and high-rise buildings.

Characteristics of European Box Transformer

Advantages: The radiation is lower than that of American box transformers because the transformers of European box transformers are placed inside a metal box to provide shielding; It is possible to set up distribution automation, and it also has the main advantages of American box type transformers.

Disadvantages: Large size, not conducive to installation, and has a certain impact on the environmental layout of the community;

Application: European style transformer is suitable for multi story residential buildings, small high-rise buildings, high-rise buildings, and other important structures
