贵州森时达电力电气有限公司Analysis of the function of power transformer
Power transformers are one of the main equipment for power plants and substations. The functions of transformers are manifold. They can not only increase the voltage, but also reduce the voltage to voltage at all levels, so as to meet the need of electricity. In a word, both the boost and the depressurization must be done by the transformer. In the process of power transmission, there will be two parts of voltage and power loss. When transporting the same power, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square of the voltage. The voltage is raised by using the transformer, and the loss of power supply is reduced.
Guizhou transformer is made up of two or more than two winding coils which are wound on the same core。 The winding is connected by alternating magnetic field, and works according to the electromagnetic induction principle。 The installation position of the transformer should be considered for easy operation, maintenance and transportation, and the safe and reliable place should be selected。 The rated capacity of the transformer must be reasonably selected when the transformer is used。 When the transformer is running in no-load, it needs greater reactive power。 The reactive power is supplied by the power supply system。 If the capacity of the transformer is too large, it will not only increase the initial investment, but also make the transformer run at no load or light load for a long time。 It will increase the proportion of no load loss, reduce the power factor and increase the network loss。 So the operation is neither economical nor unreasonable。 The transformer capacity is too small, which will make the transformer overload for a long time and easily damage the equipment。 Therefore, the rated capacity of the transformer should be selected according to the needs of the electric load, so it should not be too large or too small。 The Guizhou transformer small editor is here today。
