The introduction of oil immersed transformer
The upgrade of technical products cannot be accompanied by the progress of science and technology, so the progress of science and technology also depends on the technical requirements of production development. We want to choose a suitable oil-immersed transformer is a very important task. But before choosing, it is necessary for us to understand the basic situation of oil-immersed transformer, so as to choose the most satisfactory and most suitable products. Today, I will introduce and popularize the relevant knowledge of oil immersed transformer.
What is oil-immersed transformer ?
Oil-immersed transformer is a kind of structure is more reasonable, more excellent performance of new high-performance transformer, the three-dimensional volume core due to its three core column is the three-dimensional arrangement of an equilateral triangle, no air gap in the magnetic circuit, winding closer, three length of magnetic circuit, and is the shortest, core core column cross-sectional area is more close to the circular, thus to further improve performance, reduce loss, noise reduction, Three BALANCE, reduce the third harmonic component, the product is more suitable for urban and rural, industrial and mining enterprises power grid transformation, more suitable for combined transformers and preassembled transformer substation transformers. With oil as the main insulation means of transformer, and rely on oil as the cooling medium, such as oil immersion self-cooling, oil immersion air cooling, oil immersion water cooling and forced oil circulation. The main parts of transformer are core, winding, oil tank, oil pillow, breathing apparatus, explosion-proof tube (pressure relief valve), radiator, insulation sleeve, tap switch, gas relay, thermometer, oil purifier and so on.
What are the characteristics of oil-immersed transformers?
1,Oil immersed transformer low-voltage winding in addition to the small capacity of copper wire, generally adopt copper foil winding cylinder structure; The HIGH VOLTAGE WINDING ADOPTS MULTI-layer cylinder structure, so that the AMPERe-turn distribution of the winding is balanced, small magnetic leakage, high mechanical strength, strong resistance to short circuit.
2,The core and winding adopt fastening measures respectively. The height of the device, the low-voltage lead and other fastening parts are equipped with self-locking anti-loosening nuts.
3,Coil and core using vacuum drying, transformer oil using vacuum oil filtration and oil injection process, so that the transformer inside the moisture is reduced to low.
4,The oil tank adopts corrugated sheet, which has a respiratory function 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 the 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 and leads to the decline of insulation performance.
6,According to the above five points, it ensures that the oil-immersed transformer does not need to change oil in the normal operation, greatly reducing the maintenance cost of the transformer and prolonging the service life of the transformer.
Oil-immersed transformer is an important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. Its correct installation and use are related to the personal safety of every consumer, so it can not be ignored.
