Difference between core type and shell type transformer
Difference between core type and shell type transformer
Core type transformer |
Shell type transformer |
|
1. In this type transformer has both side winding of the core. Which means it has both arm winding
|
In this type transformer winding installed in mid arm of the core. Simply it is installed in mid-point of the core.
|
|
2. In this type transformer has only one path of the magnetic circuit or it has one path two flow of flux.
|
In this type transformer has two path of the magnetic circuit or it has two flux path.
|
|
3. In this type transformer has similar core side area. Its core side is similar than shell type transformer. It is half than shell type transformer.
|
In this type transformer has different area of core side. Its core side area is dissimilar.
|
|
4. It has two arm of core or its core has two core arms.
|
It has three core arms or it has three arms of core.
|
|
5. In this type transformer has maximum leakage flux. It has more leakage flux or more losses in this type transformer.
|
In this type transformer has minimum leakage flux. it has less leakage flux. It is better than shell type transformer.
|
|
6. In this type transformer give less output. In these type transformer losses is more than shell type transformer.
|
In this type transformer give more output than core type transformer. In these type transformer losses is less than core type transformer.
|
|
7. In this type transformer, transformer losses (copper losses, iron losses) are more than shell type transformer.
|
In this type transformer, the transformer losses (copper losses, iron losses) are less than core type transformer.
|
|
8. Maintenance of this type transformer is simple than shell type transformer. Its repair is also is simple.
|
Maintenance of this type transformer is complex than core type transformer. It repairing is complex than other.
|
|
9. In the core type of transformer, the core is surrounded by the winding.
|
In the shell type transformer, the winding is surrounding by core.
|
|
10. Its construction: for large low voltage transformer.
|
Its construction: for small high voltage transformer.
|
|
11. In larger machine, we used of core type transformer.
|
In small machine, we need of shell type transformer.
|
|
12. It have two limbs
13. We cannot provide natural cooling for this type transformer.
14. It is used for low voltage transformer.
|
It have three limbs
We can provide natural cooling for this type transformer.
It is used for high voltage transformer.
|
|
15. In this type transformer concentric cylindrical winding are used
|
In this type transformer sandwiched winding are used.
