Main Function And Features
| 110kV oil-immersed OLTC Power Transformer grounding transformer | |
| 1 | Power transformer 220kv 110kv and 66kv low-loss series |
| 2 | low loss, low noise, high reliability |
| 3 | Iron core is made of cold-rolled silicon-steel |
| 4 | Have good ability withstand short-circuit |
| 5 | The oil tank is bell type with the structure of full folding plate type, |
| 6 | Having an excellent exterior and easy for maintenance |
| 7 | Adopting capsule-type oil container, it can reduce oil aging to the lowest degree |
| 8 | Power loss: no-load loss is 30% lower than that of IEC standard |
| 9 | Reliability: All in-service product have no damages or oil leakage occurred |
| Core | 1 | Power transformer core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet |
| 2 | The material is cut with advanced Germany Geoge GmbH automatic shear line with the cut burrs controlled within 0.02mm. | |
| 3 | Power transformer silicon sheet fabrication adopts “no-upper yoke-lapped’ technology and all lapped joints of the silicon sheet are 45 full-miters | |
| 4 | Effectively improves no-load performance and reduces noises. |
| Coil | 1 | The high-voltage(HV) coil adopts an interleaved-continuous structure to improve the voltage characteristics under impact voltage and make voltage evenly distributed. |
| 2 | All stays and pads are chamfered to keep highly reliable insulation. | |
| Oil tank and accessories | 1 | Power transformer tank wall adopts wide steel sheet |
| 2 | Which will be folded into corrugated structure without splicing | |
| 3 | In this way welds aredecreased and mechanical strength is enhanced | |
| 4 | The corrugated wall has diverging effect, and thus plays arole in decrease of noise. |
