Product Details

10/0.4KV 3-phases oil type power transformer 30-2500KVA ISO IEC GB

Product Introduction

The oil-immersed transformer is one of the important pieces of equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. It reduces the 10(6)kV or 35kV network voltage to the 230/400V bus voltage used by the user. This type of product is suitable for AC 50 (60) Hz, three-phase maximum rated capacity 2500kVA (single-phase maximum rated capacity 833kVA, single-phase transformer is generally not recommended), can be used indoors (outdoor), when the capacity is 315kVA and below Can be installed on a pole, the ambient temperature is not higher than 40℃, not lower than -25℃, the highest daily average temperature is 30℃, the highest annual average temperature is 20℃, the relative humidity does not exceed 90% (ambient temperature 25℃), altitude No more than 1000m. If it is inconsistent with the above conditions of use, appropriate quota adjustments should be made in accordance with the relevant provisions of GB6450-86.

Features

1. The transformer iron core greatly reduces the no-load loss and no-load current, and the iron core is bound to ensure the tightness of the iron core and reduce noise.

2. The high and low voltage windings are made of oxygen-free copper, and the low voltage windings of 500kVA and below adopt a double-layer cylindrical structure. 630kVA and above adopt double-spiral or quad-spiral structure, and high-voltage winding adopts multi-layer cylindrical structure.

3. The transformer connection group uses Dyn11 to reduce the impact of harmonics on the power grid and improve the quality of power supply.

4. The transformer is a fully sealed structure, which prolongs the service life, does not need to hang the core and is free of maintenance.

5. The measured noise value is lower than the standard.

After this series of transformers are transported normally, the relevant parts can be installed without core checking, and the acceptance test can be carried out, and they can be put into operation after being qualified.

Performance characteristics

a. The low-voltage windings of oil-immersed transformers generally adopt a cylindrical structure with copper foil around the shaft, except for the small-capacity copper wires; the high-voltage winding adopts a multi-layer cylindrical structure to balance the ampere-turn distribution of the winding and cause leakage. Small, high mechanical strength, strong short-circuit resistance.

b. The iron core and the winding are each adopted with fastening measures. The fastening parts such as the height of the device and the low-voltage lead are equipped with self-locking lock nuts, and the non-suspending structure is adopted to withstand the shock of transportation.

c. The coil and iron core are vacuum dried, and the transformer oil is vacuum filtered and oiled to minimize the moisture inside the transformer.

d. The oil tank adopts corrugated sheet, which has a breathing function to compensate for the volume change of the oil caused by temperature changes, so this product does not have an oil conservator, which obviously reduces the height of the transformer.

e. Because the corrugated sheet replaces the oil conservator, the transformer oil is isolated from the outside world, which effectively prevents the entry of oxygen and moisture, which leads to a decrease in insulation performance.

f. According to the above five points of performance, it is ensured that the oil-immersed transformer does not need to be changed during normal operation, which greatly reduces the maintenance cost of the transformer and prolongs the service life of the transformer.
