Product Description

Product Description
S13-M series fully sealed oil-immersed transformer is suitable for dry AC 50Hz, rated working S9 series product structure design based on development. The leading idea of the design is to meet the production voltage of 20kV and below the power system, as the reliability of petroleum, metallurgy, chemical, textile, light industry, improve the performance of the product, according to the actual situation of the new S9 products, and other enterprises and dust places of distribution transformers. Readjust some loss coefficients and structures, so that the loss design value is more in line with the real side value, and SO-M series fully sealed oil-immersed transformer is a new national science and technology product, in the new type of optimization design, reasonable determination of copper-iron ratio, so that the material cost is low, the structure is reasonable.

Main feature

1. Energy saving: no-load loss reduced by 40% -50%, load loss reduced by 7% -10%;

2. Reduce line loss: no-load current reduction of more than 90%;

3. Ultra-quiet: noise reduction of 10-15 dB;

4. No interference: leakage of magnetic reduction of more than 50%;

5. Save raw materials: copper and iron costs by 20% -30%;

6. Significant economic benefits: Ten years of substation costs than the new S9 down 17.2%

Structural features

1.S13-M- transformer core: the use of material properties of not less than 30ZH120 cold-rolled silicon steel; three-phase three-column three-dimensional

symmetrical structure of the most balanced three-phase magnetic circuit; each group (volume) In dedicated iron Heart winding machine on the system, the pressure

evenly compact; core frame by vacuum annealing treatment to eliminate stress, improve electromagnetic performance; core surface coated with epoxy paint, moisture,

curing.

2.S13-M- transformer windings: the use of low-oxygen copper material paper drum flat wire or QQ-2 acetal enamelled round copper wire; low voltage coil for the

double or four round copper or new spiral, Or foil. High voltage line Ring for the multi-layer cylinder; coil oil for the corrugated structure, interlayer insulation for the

double-sided adhesive tape; low pressure and high pressure surface are added around the epoxy resin semi-viscous fiberglass belt, increase the mechanical strength.

3.S13-M- transformer body, leads: the use of insulating cardboard made of upper and lower iron yoke insulation; the use of laminated wood production balance pad

insulation; the use of laminated cardboard for the lead bracket; all fasteners are Effective locking nuts.

4.S13-M- transformer oil tank: the use of triangular structure of the whole sealed corrugated fuel tank, three-phase are set to provide heat dissipation and

compensation with the oil temperature changes caused by changes in the volume of oil volume expansion; The oil level gauge with pressure relief valve on the cover is

easy to refuel and observe the oil level, and the pressure protection is safe when the internal fault of the transformer is overvoltage.

Executive standard

1. IEC60076-1:1993 Power transformer

2. GB1094.1-1996 Power transformer

3. GB6451-2008 oil-immersed power transformer technical parameters and requirements

4. JB / T10088-2004 6KV ~ 500KV class power transformer sound level

Main technical parameters

Note:

For rated capacity for 500 kVA and below transformers,above the diagonal values of loss of load application in Dyn11 connection group,below the diagonal load loss value appliacble to Yyn0 connected node.
