35kV 1600kva On load Three Phase Power Transformer Oil immersed , Core Type
Quick Detail:
1.Low loss, low noise
2.Low partial discharge
3.High quality, efficiency
4.Safe use
5.Power transformer
Description:
O The 35KV transformers are in accordance with IEC 60076 and National Standards GB1094 Power Transformers and GB/T6451 Technical Specifications and Requirements for Three Phase Oil-immersed Power Transformers. The voltage regulation range is 5±3×2.5% kV for 35 kV class. Voltage regulation is effected by adj- usting the on-load tap changer on the high voltage side. Adjustment can be made manually or motor-operated, the output voltage on the secondary side at a required stable level. Therefore they are widely used in places where requirement of voltage quality is emphasized, such as institutes, building, hotels, hospital and factories. These transformers are new products and have better economy in operation .
1. Low loss, and significantly energy-saving. The average no-load loss is 35% lower than prescribed by National Standard GB/T 6451-2008.
2. The core laminations are made up from high-quality cold-rolled grain-oriented silicon steel sheets with chamfered joints and without punched holes, and are stacked without the upper yoke sheets in place, so that they are effectively improved no-load upper together with lower frame.
3. Zigzag directed flow of oil are provided within the windings, so that all parts of the windings can be cooled more evenly.
4. The regulating winding is a separate winding which apart from the high voltage main winding.
5. The windings of one phase are assembled into an integral phase block before placing into the core.
6. The winding manufacture, winding assembly core and winding assembly work are all proceed in totally closed clean department.
7. Core frames in the form of a flat plate are used for clamping the core, and are joined together by side beams.
8. Transformer tanks are fabricated with steel plates wide enough so that there are no weld joints on each surface.
9. Diaphragm membrane is provided within the conservator, preventing direct contact of oil with air, protecting the oil from aging.
10. Reliably sealed, and fine machined for sealed surface. Used double gasket grooves in their jointing surface and kept tight with high quality gasket material.
11. High quality paint is applied as surface finish of the tank and exposed steel parts, after shot-blasting and pretreatment, thus ensuring a durable life and glossy surface.
12. Quality assurance rules are also observed for all insulating parts, from raw material to final assembly.
Applications:
Electric arc furnace transformer is power transformer which is designed according to work principle, lead character and operation characteristic and can be used for steel and non-ferrous metal smelting, extracting various ferroalloys, silicon compounds and extraction of pure silicon.
