The characteristics and differences between the American Box Transformer and the European Box Transformer

Features and Application of American Box Transformer

Among them, the combined substation, also known as the American box substation, is divided into two types according to the fuel tank structure, the common box type and the sub box type. Its advantages are small size, small footprint, easy installation, and coordination with the environment of the community, which can shorten low-voltage cables. The length of the power supply is reduced, the line loss is reduced, and the cost of the power supply is reduced. However, the shortcomings include low power supply reliability; no electric mechanism, no power distribution automation device; no capacitor device; due to the different civil engineering foundations of different capacity box transformers, when the box transformer is overloaded or the user increases the capacity, the civil engineering needs to be rebuilt. A longer period of power outage transformation will increase the difficulty of the project at the same time.

Application: 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 change, the impact on the residents is not large, but it is not suitable for small and high-rise buildings.

Features and application of European Box Transformer

The prefabricated substation is also known as the European-style box substation, and it adopts two types: ring network type and terminal type. The advantage is that the radiation is lower than that of the American box transformer, because the transformer of the European box transformer is placed in the metal box to play a shielding role; power distribution automation can be set up, and there are the main advantages of the American box transformer. There are also disadvantages such as large size, which is not conducive to installation, and has a certain impact on the environmental layout of the community; it is widely used in multi-storey residential buildings, small high-rise buildings, high-rise buildings and other more important buildings.

The main difference between the American Box Transformer and the European Box Transformer

The high-voltage protection of Meibian is composed of plug-in fuse, backup fuse + load switch; the high-voltage protection of Europe transformer is composed of pressure type, vacuum or sulfur hexafluoride load switch + fuse according to the switching frequency of load; flexible capacity.

The biggest difference between Meibian and Eurobian is in the high-voltage part. The high-voltage wiring of Meibian is only ring network or terminal power supply. The Eurobian consists of an independent high-voltage unit, the form can be customized according to customer requirements. Since each functional unit of Eurobian is independent, each unit can be customized according to user requirements. Due to the high pressure limitation and its small size, Meibian has far less flexible functions than Oubian. But the cost of Meibian is much cheaper than that of Europe.

In the near future, box-type substations will be widely used in China’s cities, rural areas, industrial and mining enterprises, and public buildings. It will be more and more popular due to its high quality and low price, flexible and convenient configuration, and small footprint. Used by more people, the operation level of China’s power grid has reached a new level.
