S11-M Three Phase 33kv to 400V Oil-Immersed Distribution Power Transformer

Instruction

The transformer is a transformer whose interior is isolated from the air surrounding, so the transformer oil can not absorb the outer moisture and the oxygen since the change of transformer's volume could be fixed with the flexibility of corrugated tank structure. Then the aging speed of insulated material will be decreased. Before running the machine, the work of core suspension checkup is not necessary. Clients could also be free from the later maintenance and reparation. The reliability of products is visibly upgraded. Products is designed with PCCAD, the characters are conformed to IEC 60076 and GB 1094, and passed qualification ISO 9001.

Product specification

S11-M Three Phase 33kv to 400V Oil-Immersed Distribution Power Transformer

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.
