Product definition of dry-type transformer

Distribution transformers are one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. They reduce the 10⑹kV or 35kV network voltage to the 230/400V bus voltage used by users. This type of product is suitable for AC 50 (60) Hz, three-phase maximum rated capacity 2500kVA (single-phase maximum rated capacity 833kVA, single-phase transformers are generally not recommended)
1) When there are a large number of primary or secondary loads, it is advisable to install two or more transformers. When any of the transformers is disconnected, the capacity of the remaining transformers can meet the power consumption of the primary and secondary loads. The primary and secondary loads should be concentrated as much as possible and should not be too dispersed.
2) When the seasonal load capacity is large, it is advisable to install a dedicated transformer. For example, the air conditioning and refrigeration load in large civil buildings, heating and electric heat load, etc.
3) When the concentrated load is large, it is advisable to install a dedicated transformer. Such as large heating equipment, large X-ray machines, arc furnaces, etc.
4) When the lighting load is large or the use of a common transformer for power and lighting seriously affects the lighting quality and bulb life, a dedicated lighting transformer can be installed. In general, power and lighting share a transformer.
