What is the concept of specialized substation? What kind of power system needs to apply for a dedicated substation?
According to the principle of electromagnetic induction. Transformers can be divided into power transformers, test transformers, instrument transformers and special transformers according to their uses. Power transformer is a necessary equipment for power users to transmit, distribute and distribute electricity.
Extended data:
It consists of two or more coil windings wound on the same iron core, which are connected by alternating magnetic field and work according to the principle of electromagnetic induction. The installation position of the transformer should be convenient for operation, maintenance and transportation, and a safe and reliable place should be selected. When using the transformer, the rated capacity of the transformer must be reasonably selected. When the transformer is in no-load operation, it needs large reactive power.
The function of transformer is various, which can not only increase the voltage to transmit electric energy to the power-consuming areas, but also reduce the voltage to various use voltage levels to meet the power demand.
In a word, both step-up and step-down must be completed by transformer. In the process of power transmission in power system, there will inevitably be losses of voltage and power. When transmitting 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. Transformers are used to increase voltage and reduce power transmission loss.
