Overview

S13-M-315/10 fully sealed oil-immersed power transformers with low loss, low noise, high efficiency advantages, can achieve good energy saving effect and reduce pollution. Fully sealed transformer and ordinary oil - immersed change Compared to the removal of the oil conservator, the change in oil volume is automatically adjusted by the elasticity of the ripple of the corrugated fuel tank, the transformer is isolated from the air to prevent and slow the deterioration of the oil and the insulation aging, Operational reliability, uptime maintenance.

Model and meaning

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-(315)/10 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-(315)/10 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-(315)/10 Transformer body, lead: 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-(315)/10 transformer fuel 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
