500 KVA 3D Core Oil Immersed Transformers For Industrial Distribution System

Product Specification

500kva Oil Immersed Transformers, 3D Core Oil Immersed Transformers, Factory Supply Power Transformers

500 kva Transformer 10/0.4KV three-phase power transformer oil immersed power transformer is

one of the important equipment in the power supply and distribution system for industrial and mining

enterprises and civil buildings. It reduces the voltage of 10 (6) kV or 35kV network to the 230/400V

bus voltage used by the user. This kind of product is suitable for the exchange 50 (60) Hz, the maximum

rated capacity of three phase 2500kVA (single phase maximum rated capacity 833kVA, generally not

recommended single phase transformer), can be used in the indoor (outside), the capacity of 315kVA

and below the installation of the rod, the ambient temperature is not more than 40 degrees C, not less

than -25, the maximum daily average temperature of 3 The maximum annual average temperature is 20 C,

the relative humidity is no more than 90% (the ambient temperature is 25 C), and the altitude is less than

1000m at 0 C. In case of discrepancy with the above terms of use, appropriate adjustment shall be made

according to the relevant provisions of GB6450-86.A, oil immersed transformer low voltage winding in

addition to small capacity of small capacity of copper wire except for copper wire, generally use copper

foil round the cylinder type structure, high voltage windings adopt multi-layer cylinder structure, make

the winding distribution balance, magnetic flux leakage is small, mechanical strength is high, and short

circuit ability is strong.B,The fastening measures of B, iron core and windings are each adopted, the

fastening parts such as the height of the device, the low pressure lead and so on are all with self locking

anti loose nuts, and the structure of no suspension is used to withstand the shock of transportation.
C, coil and core are vacuum dried, vacuum oil and oil injection technology are applied to transformer

oil to minimize the moisture inside the transformer.D, oil tank with corrugated plate, it has the function of

breathing to compensate for the change in the volume of oil caused by temperature change, so the product

has no oil storage cabinet, obviously reducing the height of the transformer.E, due to the replacement of the

oil storage cabinet by the corrugated sheet, the transformer oil is isolated from the outside, which effectively

prevents the entry of oxygen and water and leads to the decrease of insulation performance.
