Amorphous Transformer |
|
|
| Product name：Amorphous Transformer |
| Item：9-3 |
| Details： |
| |
Description
SBH15-M series amorphous alloy core transformer is made according to Chinese standard, equals to IEC standard. No-load loss of this series transformer is 75% less than that of CRGO distribution transformer.
Structure features
-Amorphous alloy is a new strip material which has no crystal structure and so its magnetizing power is small, high resistivity, low eddy current loss.
- Core is of wound core structure, three-phase 5-column type, section is rectangular.
- Coil is rectangular, HV winding is wound by enameled wire; LV winding is wounded by foil, increased short-circuit throughput!
- Transformer connecting symbol adopts Dyn11, avoiding influence by high harmonic, stronger un-balanced load resisting capability.
- Vacuum oil filling avoids gas in windings completely
- Deletes oil conservator, adopts fin type radiator for cooling

Notes
|
1. Short-circuit impedance of 400/500 KVA transformers @ 10KV and less is 4%; that @ 20kV is 4.5%.
|
|
|
2. LV winding of 50 KVA and100KVA transformers are not foil type coils.
|
|
|
3. Special sizes or requirements can be discussed and special designed.
