What are the specifications of the transformer model?

A Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. People who have seen the transformer and are careful or attentive will know it. There are a lot of letters on the top of the transformer, everyone is not very curious about the meaning of the letters on the transformer? Transformers not only have these letters, as well as the specifications of the transformer model, then the transformer has any specifications model? Just Xiaobian mentioned those What does the letter on the transformer represent? Xiao Bian will take everyone to find out.

What are the specifications of the transformer?

1. There are actually many types of transformers in specifications, and transformers of different specifications have different meanings. Our common transformers such as dry-type transformers, its model is “SCB10-1000KVA/10KV/0.4KV”, in which the dry-type transformer means that, S represents the transformer is a three-phase transformer, if it is to change S A D indicates that the transformer is single phase. C indicates that the transformer winding is a resin cast solid, which is a dry-type transformer. B denotes a foil winding. If B is replaced by R, it is represented by a winding type winding. If it is L, it is represented by an aluminum winding. If it is Z, it is represented by on-load voltage regulation. If it is copper, it is not marked. The 10 is a design number, also called a technical serial number. 1000KVA indicates the rated capacity of this transformer (1000 kVA). 10KV means a rated voltage and 0.4KV means a secondary rated voltage.

2. The types of power transformers that are common in our lives are usually composed of symbols representing the number of phases, cooling methods, voltage regulators, winding cores, and other materials, as well as transformer capacity, rated voltage, and winding connection. For example, in the meaning of the power transformer model number “SFSZ9-31500/110”, S means three-phase, F means air-cooled, S means three-winding, Z means on-load voltage regulation, and 9 means Design number 9 type. The 31500 is a transformer rated capacity of 31500 kVA, and 110 represents a primary rated voltage of 110 kV.
3. In the specification of the transformer, if it is divided according to the voltage level of the transformer, the model of the transformer can be divided into 1000KV, 750KV, 500KV, 330KV, 220KV, 110KV, 66KV, 35KV, 20KV, 10KV, 6KV and so on.
