Power Transformers - Basic Structure
Most of the usual power transformers are oil-immersed. The iron core and windings are immersed in a tank full of transformer oil, and the end points of the windings are led to the outside of the tank through insulated bushings for connection with external lines. Therefore, the power transformer is mainly composed of five parts: 1, iron core; 2, with insulation of the windings; 3, transformer oil; 4, tank; 5, insulating bushings.
Iron core: The iron core of the transformer is the magnetic circuit of the transformer. As the magnetic flux in the transformer core is an alternating magnetic flux, in order to reduce eddy current losses, the transformer core is stacked with electrical steel sheets.
Winding: according to the arrangement of the winding in the core method of classification, the transformer can be divided into two categories of iron core type and iron shell type. The basic form of transformer winding with core type and overlapping type two kinds, iron core type transformer commonly used with core type winding, iron shell type transformer commonly used overlapping type winding.
Transformer oil: the role of transformer oil is double: 1, can enhance the insulation; 2, iron core and winding due to loss and heat, through the oil in the heat convection effect of heat transfer to the surface of the iron box, and then by the surface of the iron box scattered to the surrounding.
Tank: the role of the tank is to reduce the oil and air contact area to reduce the rate of oxidation of the oil and intrusion of water into the transformer; Insulation bushings: insulation bushings by the center of the conductive copper rod and porcelain bushings and other components.
The role of power transformer
Power transformer is one of the main equipments of power plant and substation. The role of the transformer is multi-faceted not only to raise the voltage to the power area, but also to reduce the voltage for all levels of voltage to meet the needs of electricity. In short, boosting and bucking must be completed by the transformer. In the process of power system transmission of electrical energy, will inevitably produce voltage and power losses in two parts, in the delivery of the same power voltage losses and voltage is inversely proportional to the power loss and voltage is inversely proportional to the square of the power loss. Utilizing a transformer to increase the voltage reduces the power delivery losses.
