Product Description
What is a Transformer Core?
A transformer core is a structure of thin laminated sheets of ferrous metal (most commonly silicon steel) stacked together, that the primary and secondary windings of the transformer are wrapped around.
A transformer core is a structure of thin laminated sheets of ferrous metal (most commonly silicon steel) stacked together, that the primary and secondary windings of the transformer are wrapped around.
Parts of the Core
A transformer core is composed of limbs and yokes that are joined together to form a single structure around which the coils are placed. The manner in which the respective yoke and limbs join together will depend on the type and design of the core.
Core Construction
The densely packed laminated sheets that cores are constructed from, reduce overheating and circulating currents in the core. This lowers the transformers energy loss. Removing any air gaps between the laminations will result in a higher efficiency as well. A core design with large gaps between laminated sheets will yield higher no load or iron losses and a lower efficiency.
Type of material cores are made from
The earliest transformer cores utilized solid iron, however, methods developed over the years to refine raw iron ore into more permeable materials such as silicon steel, which is used today for transformer core designs due to its higher permeability. Also, the use of many densely packed laminated sheets reduces issues of circulating currents and overheating caused by solid iron core designs. Further increases in core design are made through cold rolling, annealing, and using grain oriented steel.
Laminated Core
Also referred to as a stacked core or E core, this type of core design employs a step-lap mitred configuration for the core sections. The laminations for each limb are grouped together in groups of 5 - 7 sheets-these groups are referred to as books. These sections of core steel are mitre cut and fit together as
Distributed Gap Core
Commonly referred to as a wrapped core, this core design is used in 3-ph and 1-ph distribution transformers. Distributed gap cores utilize a simple core clamp design which leads to faster assembly times and lower manufacturing costs. Another advantage of the distributed gap design is that there is only one cut per layer of laminated sheet. This type of core configuration is also referred to as a shell since the windings are surrounded by the core. As we mentioned earlier, this shell type design typically yields lower transformer losses. It's efficient and lower cost design makes it the ideal choice for distribution transformers.
