5000 KVA Transformer

5000 kVA Transformer Specification

The 5000 kVA transformer is a robust and reliable power transformer built for heavy-duty industrial applications. With a power rating of 5000 kVA, it is capable of handling large loads and is ideal for use in substations, power plants, and industrial settings.

The transformer has a primary voltage of 11000 V and a secondary voltage of 690 V, with a YD11 vector group configuration. It has three phases and a frequency of 50/60 Hz. The transformer has an impedance of 6% and cooling options include ONAN, ONAF, and ODAF.

The temperature rise of the transformer is 65°C/55°C, and it has an insulation level of 75 kV (BIL), making it highly resistant to voltage surges. The transformer is of the oil-immersed type, and the tap changer is off-circuit. Its protection rating is IP23, making it suitable for use in outdoor environments.

The transformer is highly efficient, with an efficiency rating of 99%. It weighs 16000 kg and has dimensions of 3750 x 2050 x 2450 mm. With its high power rating, reliability, and durability, the 5000 kVA transformer is the ideal solution for heavy-duty industrial applications.

Oil Immersed Transformer Product Introduction:

1000kVA and above oil-immersed transformers must be equipped with outdoor signal thermometers and can be connected to distant signals. 800kVA and above oil-immersed transformers should be equipped with gas relays and pressure protection devices, oil immersed transformers below 800kVA according to the requirements of use, in consultation with the manufacturer, gas relays can also be installed. Dry transformers should be equipped with temperature measuring devices according to the requirements of the manufacturer, generally 630kVA and above transformer installation. Fully sealed oil-immersed distribution transformers with a voltage class of 35kV and below and a capacity of 31500kVA and below Including oil-immersed transformer, S11 oil-immersed transformer, S13 oil-immersed power transformer, S9, S11, S13, D11, SZ11, SCB10, SCB11, SCRBH15, SH15-M, KS11, KBSG and other series transformer products. The full-sealed oil-immersed transformer adopts full-filled oil-sealed type, and the corrugated shell oil tank ADAPTS its elasticity to the expansion of oil to become a sealed oil tank. This kind of product has been widely used in the construction of urban and rural power grids and key projects.

Oil-Immersed Transformer Structure Features:

1 Transformer core selection of high-quality cold-rolled oriented silicon steel sheet, the use of automatic transverse cutting process and the application of stepped joints (Step-Lap) process manufacturing, improve the distribution of magnetic flux density inside the core, reduce the vibration of the core dynamic energy, effectively reduce noise, reduce loss.

2. Coil selection of high strength enameled wire (or paper covered wire) winding, cylinder type (or cake) structure, ampere-turns distribution, reasonable insulation structure, with strong short-circuit resistance.

3. The oil-immersed transformer body is fastened with a loose-proof structure, and the fastening part is equipped with a self-locking loose-proof nut, and no hanging is adopted

The core structure can ensure that it is not loose when running after long-distance transportation.

4. The corrugated sheet of the corrugated oil tank replaces the oil storage tank, and the corrugated sheet can expand and shrink with the change of the volume of the transformer oil.

Make the transformer isolated from the atmosphere, prevent and slow down the deterioration of oil and insulation moisture, enhance the reliability of operation, normal operate maintenance-free.

5. Equipped with "telemetry" signal thermometer and pressure release valve, enhance the reliability of transformer operation
