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
