Distribution transformers are one of the important equipment in the power supply and distribution systems of industrial and mining enterprises and civil buildings.
Distribution transformers are one of the important equipment in the power supply and distribution systems of industrial and mining enterprises and civil buildings.
It reduces the network voltage of 10 (6) kV or 35kV to the 230/400V bus voltage used by the user. This product is suitable for AC 50 (60) Hz, three-phase maximum Nameplate capacity 2500kVA (single-phase maximum Nameplate capacity 833kVA, single-phase transformer is generally not recommended), and can be used indoors (outdoors). When the capacity is 315kVA or less, it can be installed on the pole. The ambient temperature is not higher than 40 ℃, not lower than -25 ℃, the maximum daily average temperature is 30 ℃, the maximum annual average temperature is 20 ℃, and the relative humidity is not more than 90% (ambient temperature is 25 ℃), The altitude shall not exceed 1000m. If it does not comply with the above usage conditions, appropriate quota adjustments should be made in accordance with the relevant provisions of GB6450-86.
The low-voltage winding of oil immersed transformers generally adopts a cylindrical structure with copper foil winding, except for small capacity copper wires; The high-voltage winding adopts a multi-layer cylindrical structure, ensuring a balanced distribution of ampere turns, low magnetic leakage, high mechanical strength, and strong short-circuit resistance.
The iron core and winding each adopt fastening measures, and the fastening parts such as the height and low-voltage leads of the device are equipped with self-locking anti loosening nuts. They adopt a non hanging core structure and can withstand transportation bumps.
The coil and iron core are vacuum dried, and the transformer oil is filtered and injected through a vacuum process to reduce the moisture inside the transformer.
9e, because the corrugated sheet replaces the oil storage tank, the transformer oil is isolated from the outside world, which effectively prevents the entry of oxygen and water and leads to the decline of insulation performance.
According to the above five points, it ensures that the oil-immersed transformer does not need to change oil in normal operation, greatly reducing the maintenance cost of the transformer, and extending the service life of the transformer.
