Deskripsi Produk
Distribution transformer is one of the important equipments in power supply and distribution system of industrial and mining enterprises and civil buildings, which reduces the 10(6) kV or 35 kV network voltage to the 230/400 V bus voltage used by the user. 50(60) Hz, for AC Maximum three-phase rated capacity 2500 kVA (maximum single-phase rated capacity 833 kVA, Single-phase transformers are not generally recommended), Can be used indoors, Can be installed on a pole at kVA 315 and below, Ambient temperatures not higher than 40ºC, At least -25ºC, A maximum daily average of 30ºC, A maximum annual mean temperature of 20ºC, relative humidity not exceeding 90%(ambient temperature 25ºC), Elevation not exceeding m.1000 If not in accordance with the above conditions of use, According to the relevant provisions of the GB6450-86, Make appropriate quota adjustment. Performance Characteristics of Oil-immersed Transformer 1. Except for the small capacity of copper wire, the low voltage winding of oil-immersed transformer generally adopts the cylindrical structure of copper foil winding, and the high voltage winding adopts multi-layer cylindrical structure, which makes the winding balanced in distribution, small magnetic leakage and high mechanical strength. Strong short circuit resistance.
2. iron core and winding adopt the fastening measures, the fastening parts such as the high and low voltage lead of the device are all with self-locking anti-loosening nuts, which adopt the structure of no lifting center and can withstand the shock of transportation.
3. coil and core are vacuum dried, transformer oil is vacuum oil filter and oil injection process, so that the moisture inside the transformer is minimized.
4. oil tank adopts corrugated sheet, it has the function of breathing to compensate for the volume change of oil caused by temperature change, so the product has no oil storage tank, which obviously reduces the height of transformer.
5. 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, which leads to the decline of insulation performance.
6. according to the above five performance, the oil-immersed transformer does not need to change oil in normal operation, which greatly reduces the maintenance cost of the transformer and prolongs the service life of the transformer.
