For example: SFZ-/ means that the three-phase natural circulation air-cooled on-load voltage regulation, the rated capacity is, the rated voltage of the high-voltage winding is llokV power transformer.
S9-/10 means that the three-phase oil-immersed self-cooling, double-winding non-excitation voltage regulation, rated capacity, and rated voltage of the high-voltage side winding are power transformers.
SC8-/10 means three-phase dry-type casting insulation, double-winding non-excitation voltage regulation, rated capacity, and rated voltage of high-voltage side winding is lokV power transformer.
-M(R)-/10 means three-phase oil-immersed self-cooling, double-winding non-excitation voltage regulation, wound iron core (circular section), sealed type, rated capacity, and rated voltage of the high-voltage side winding is a power transformer.
-M-50/10 means three-phase oil-immersed self-cooling, double-winding non-excitation voltage regulation, amorphous alloy iron core, sealed type, rated capacity, and rated voltage of high-voltage side windings are power transformers.
Power transformers can be classified according to the winding coupling method, the number of phases, the cooling method, the number of windings, the material of the winding wire and the voltage regulation method. However, this classification is not enough to express all the characteristics of the transformer, so in addition to expressing the classification characteristics in the transformer model, it is also necessary to mark its rated capacity and rated voltage level of the high-voltage winding.
Some new distribution transformers with special structure, such as amorphous alloy core, wound core and sealed transformer, are represented by H, R and M respectively in the model.
SFCSZ4-/ means:
S-three-phase, F-air cooling, C-dry type, S-three windings, Z-on-load voltage regulation, 4-design serial number,-capacity,-voltage level of high voltage side.
