Distribution transformer for industrial and mining enterprises and civil construction power supply and distribution system in one of the important equipment, it will be 10 kV or 35kV network voltage to the user used 230/400v bus voltage. This product is suitable for AC 50(60)Hz, three-phase maximum rated capacity 2500kVA(single-phase maximum rated capacity 833kVA, single-phase transformer is generally not recommended)
1) When there is a large number of primary or secondary loads, two or more transformers should be installed. When any one of the transformers is disconnected, the capacity of the remaining transformers can meet the power consumption of the primary and secondary loads. One, two loads as far as possible concentrated, should not be too dispersed.
2) When the seasonal load capacity is large, a special transformer should be installed. For example, large civil S4270D27-29 27 2005.7.29, 3:24AM Load of air conditioning refrigerating machine and electric heating load in building.
3) When the concentrated load is large, a special transformer should be installed. Such as large heating equipment, large X-ray machine, arc furnace and so on.
4) When the lighting load is large or the power and lighting use of a common transformer seriously affects the lighting quality and the life of the bulb, a special lighting transformer can be set. In general, the power and lighting share the transformer.
Select transformers according to the use environment:
1) Under normal medium conditions, oil-immersed transformer or dry transformer can be selected, such as independent or attached substation of industrial and mining enterprises, agriculture, independent substation of community, etc. Alternative transformers are S8, S9, S10, SC(B)9, SC(B)10, etc.
2) In multi-storey or high-rise buildings, non-combustible or refractory transformers should be selected, such as SC(B)9, SC(B)10, SCZ(B)9, SCZ(B)10, etc.
3) In places where the safe operation of transformers is seriously affected by dust or corrosive gases, closed or sealed transformers should be selected, such as B S9, S9 -, S10-, SH12-M, etc.
4) High and low power distribution devices without inflammable oil and distribution transformers without oil immersion can be installed in the same room. In this case, the transformers should be equipped with IP2X protection shell for safety.
