S9, S10, 35KV level low loss power transformer description
S9, S10, 35KV low-loss power transformers are three-phase oil-immersed R-type, stepped wound core distribution transformers. The stepped three-pillar inner and outer frame rolling structure is spot-welded on the outermost layer without binding. The core material is cold-rolled silicon steel sheet such as DQ133-30 (type 9), 30ZH120 (type 11), 23ZH90 (type 13), and the core material used in actual production is not lower than the drawing requirements. The iron core is continuously rolled without seams. The R-shaped core piece width ensures that the cross-section of the core is round, and the stepped core is made of multi-level piece width rolling. After the core coil is formed, vacuum annealing is carried out to eliminate the stress and reduce the loss.
S9, S10, 35KV low-loss power transformers adopt a fully sealed corrugated oil tank structure, and the transformer oil does not contact the surrounding air, so the transformer oil will not absorb external moisture, thereby not reducing the insulation strength; in addition, because oxygen cannot enter the tank, it is avoided This improves the aging of the insulating material, improves the service life of the product, and also improves the social benefits.
Technical characteristics
Energy saving: Compared with GB/T6451, the no-load loss of 35KV class is reduced by an average of 30%, load loss is reduced by an average of 25%, and operating costs are reduced by an average of 20%.
Long service life: The transformer oil tank adopts a fully sealed structure, and the oil tank and the tank can be connected with bolts or welded together, and the transformer oil does not contact the air to extend the service life.
High operational reliability: The relevant parts of the fuel tank seal have been improved to increase the reliability, and the process level is improved to ensure the reliability of the seal.
Small footprint: S9-M and S11-M series transformer oil tanks use corrugated plate radiators. When the oil temperature changes, the corrugated plate thermally expands and contracts can replace the role of the oil storage tank. The corrugated plate fuel tank has a beautiful appearance and a small footprint .
