The Use Of Oil In Oil-immersed Power Transformer
Oil-immersed transformer oil is inseparable from the use of oil-immersed transformer, oil-immersed transformer oil is the energy of oil-immersed transformer operation, is the main driving force to achieve the performance of oil-immersed transformer oil, the role of oil-immersed transformer oil is also relatively large, careful study of oil-immersed transformer oil for the use of oil-immersed transformer and the realization of performance are playing a good role.
What is the common oil-immersed transformer oil? What does it do? Let's take a look at the role of oil-immersed transformer oil:
Oil-immersed transformer oil: it is a fractionated product of petroleum, its main components are alkane, naphthenic saturated hydrocarbons, aromatic unsaturated hydrocarbons and other compounds.
The main role of oil-immersed transformer oil:
(1) Insulation effect: oil-immersed transformer oil has much higher insulation strength than air. The insulation material is immersed in oil, which not only improves the insulation strength, but also protects against the erosion of moisture.
(2) Heat dissipation: the specific heat of oil-immersed transformer oil is large, and it is commonly used as a coolant. The heat generated during the operation of the oil-immersed transformer makes the oil near the iron core and winding expand and rise. Through the upper and lower convection of the oil, the heat is dissipated through the radiator to ensure the normal operation of the oil-immersed transformer.
(3) Arc elimination: On the on-load regulator switch of the oil circuit breaker and the oil immersed transformer, the contact will produce an arc when it is switched. Because the oil-immersed transformer oil has good thermal conductivity, and can touch a large amount of gas under the action of high temperature arc, resulting in greater pressure, thus improving the arc extinguishing performance of the medium and making the arc quickly extinguished.
Since the role of oil-immersed transformer oil is relatively large, the oil-immersed transformer oil should be selected with good quality and reliable oil-immersed transformer oil to truly achieve the purpose of oil-immersed transformer operation.
