The not the same between American type substation and European type substation
Now on the market substation by the type of basic divided into American substation and European substation, before we have been elaborated in the article before the knowledge of the two products, today we are the difference between the two products make a comparison, let you can more intuitive to see the advantages and disadvantages of the two products.
European-style substation
The main components of European-type substation include transformer, 10KV ring network switch cabinet, low voltage capacitor, low voltage switch, etc.
Advantages: noise and type station and type I station; radiation is lower than the American box change, because the European box transformer is placed in the metal box body shielding role; can set distribution automation, not only has the advantages of type station and type I station, but also the main advantages of the American box transformer.
Disadvantages: the volume is large, is not conducive to the installation, the layout of the environment of the community has a certain impact.
American substation
The main components of the American-style substation include transformer, 10KV ring network switch, 10KV cable plug, low-voltage pile head box, etc.
Advantages: small volume and small area, easy to place, easy to camouflage, easy to coordinate with the environment of the community. It can shorten the length of low-voltage cable, reduce the line loss, but also reduce the cost of power supply.
Disadvantages: low power supply reliability; no electric mechanism, no distribution automation device; no capacitor device, adverse to reduce line loss; higher noise than type station and V station, because the transformer and V station are indoor, sound insulation; also, the concentrated electromagnetic radiation of type station and V station into multipoint radiation; because the civil foundation of different capacity box, the box is inconvenient; when the box overload or user capacity, civil engineering to be rebuilt, will have a long blackout time, increase the difficulty of engineering.
Because the structure of the box change is also used in different places, the power supply network is also different
Because the structure of American box change and European box change is different in reliability, so the application occasion is also different. When the capacity of the American box is smaller and the building area is large, the applied box will increase a lot, thus increasing the load point on the overhead line; when reducing the load point of the overhead line, we must increase the number of box connections, so that the network structure is weak. To overcome the problem of weak network structure caused by small capacity box change, it is best to use the ring website to solve.
1. Suitable place for American box change
In view of the structural characteristics and advantages and disadvantages of the American box transformer, the American box transformer is suitable for the electricity consumption of multi-storey houses and other unimportant buildings with relativel-y low power supply requirements. According to our actual use, the American box transformer with a small ring network switch station, fully suitable for the power supply of multi-storey residential needs. Because it is the box change failure, the impact on the residents is not big, but not adapted to the small high-rise and high-rise.
2. Suitable place of European-type box change
European box change is suitable for multi-storey housing, small high-rise, high-rise and other more important buildings.
With the development of economy and the growth of the power sector, the demand for box substation is increasing, there are many specialized production box substation professional suppliers, such as SHZ Power is a professional box substation Chinese manufacturers, if you want to know more about box substation, want to find high quality box substation, welcome to email inquiries at any time.
