630 Kva Three Phase Oil Immersed Transformer

Product Main Features:

1.Three Phase oil immersed transformers are available with either natural cooling or forced air cooling systems. In both cases, insulating oil plays an important role in heat transfer and temperature control. To ensure reliable operation and efficient heat dissipation, high grade insulating oil and dependable cooling equipment are carefully selected during the manufacturing process.

2. The windings of 630 kva three phase oil immersed transformers are typically designed with laminated silicon steel cores and multi layer insulation structures.It is commonly to use advanced automatic stacking and welding technologies to improve both mechanical stability and electrical performance. The core and structural components are manufactured from high quality cold rolled steel materials for enhanced durability and operational reliability.

3. High conductivity copper conductors are generally used for the manufacturing of 630 kva three phase oil immersed transformer windings in order to improve thermal performance and operational safety.Furthermore, it could reduce budgets about 40% to 65% of total value, if the windings of 630 kva three phase oil immersed transformer adopts aluminum conductors. On the other hand, the insulation system mainly consists of oil impregnated insulating paper immersed in transformer oil. All insulation materials are selected and tested in accordance with the relevant requirements of IEC 60076 standards.

4. Several cooling methods can be applied to three phase oil immersed transformers, including natural cooling, forced air cooling, and forced oil air cooling systems. Depending on the rated capacity and application requirements,three phase oil immersed transformers may operate individually, in parallel, or as part of an integrated cooling arrangement.

5. Windings of three phase oil immersed transformers are commonly installed in either vertical or horizontal configurations, depending on the structural design and operational requirements of the equipment. However, the 630 kva three phase oil immersed transformers adoptvertical arrangement to achieve a better performance on heat dissipation, and short circuit withstand capability.

Technical Specification:

Application Range of 630 kva three phase oil immersed transformer

1.630 kva three phase oil immersed transformers are suitable for AC power systems with a frequency of 50 Hz and rated voltages up to 35 kV. They are mainly used for voltage conversion and as power sources for control circuits in electrical systems.

2.630 kva three phase oil immersed transformers are widely applied in urban and rural power networks, industrial facilities, mining enterprises, as well as critical infrastructure and major engineering projects. During full load operation, the temperature rise of a 630 kva three phase oil immersed transformer shall remain within the permissible limits specified by the manufacturer.

3. For transformers operating in harsh environmental conditions, maintenance should not be carried out during rain, snow, or severe weather in order to avoid insulation damage and ensure operational safety.

4.630 kva three phase oil immersed transformers should not be operated in environment above +50°C for standard applications, and operation below -60°C is strictly prohibited, as extremely low temperatures may cause serious damage to internal components and insulation systems.

5. The insulating oil used as the cooling medium must remain clean and free from corrosive or explosive contaminants to ensure safe and stable transformer operation.

6. For installations in high temperature areas or hazardous environments, insulation testing should be conducted before the 630 kva three phase oil immersed transformer is put into service.
