S11-S13 11kV 1000kVA low loss transformer

Daelim S11-S13 series 11kV 1000kVA transformers are made of high-quality materials, and new technology and materials are used in coil, body, insulation, etc., with small no-load and load losses, uniform magnetic circuit, more reliable performance and structure, and energy saving.

The S11 series is a fully sealed iron core distribution transformer. The low noise and low loss transformers developed in recent years have no joints in the iron core, which greatly reduces the no-load loss and no-load current, and reduces the no-load current. 60%~80%, the high and low voltage coils are continuously wound on the core column, the windings are compact and the concentricity is good, which further enhances the anti-theft performance of the transformer.

S13 series is a transformer with low no-load loss, low no-load current, low noise, and remarkable power-saving effect, which improves the voltage quality and reliability of the power supply. It is green energy-saving equipment that is conducive to environmental protection. The latest products are promoted and used in the technological transformation project.

S11 and S13 series of fully sealed three-phase three-phase wound core transformers are different from traditional flat laminated core transformers. The iron core is composed of three-phase column yokes arranged in a three-dimensional triangle with a single frame. Each cylinder is continuously rolled by high-quality cold-rolled silicon steel strip, and the width is cut straight or curved by a CNC cutting machine.

The strip is wound on the core winding machine to form a near-circular or folded arc frame, and then vacuum nitrogen-filled annealing is performed to eliminate processing stress, re-orient the lattice, increase magnetic permeability, and improve electromagnetic performance; high and low voltage coils use special The winding machine is directly wound on the iron core column paper tube, and the overall structure is solid and compact. impact.

S11-S13 11kV 1000kVA transformer features:

1. Economical and environmentally friendly with good performance

The transformer products of the S11-S13 series have lower losses and currents than the S9 series. Because the iron core (the cross-section is a pure circle) is continuously wound, the orientation of the silicon steel sheet is fully utilized, and the iron core structure is in a natural tightening state, without the need for clamps to tighten, avoiding the performance deterioration caused by clamping, the no-load loss is reduced by 20-45%, and the no-load current is reduced by 60%-80%.

2. Longer life of the transformer

The fuel tank is a fully sealed structure. The fuel tank and the edge of the fuel tank can be fixed with bolts or welded to death. The insulating oil does not come into contact with the air, and the aging speed of the insulating performance is slowed down, thereby prolonging the service life;

3. Low noise

The noise is reduced by more than 10 decibels. The transformer core itself is a seamless whole, and the structure is compact. The noise level during operation is reduced by 7-10dB, which is very suitable for installation in buildings and living areas.

4. Reliable operation

The parts in the fuel tank have been improved, the reliability has been increased, and the technological level has been improved to ensure the reliability of the seal.

5. The transformer is small in size

S11 and S13 use corrugated plate radiators. When the oil temperature changes, the corrugated plate expands and contracts when the oil temperature changes. It can replace the role of the oil conservator.
