Product Description

              Working principle of power transformer: A transformer is a stationary electrical energy converter that transmits electrical energy without changing its frequency. power systems, the higher the voltage for transmitting the same power, the smaller the current and the power loss on the transmission line; the cross-sectional area of the line can also be reduced, thereby reducing the metal usage of the conductor. Functions of power transformers: Power transformers are one of the main devices in power plants andations. They have multiple functions, including increasing the voltage to send electrical energy to the power consumption area, and reducing the voltage to various usage voltages to meet power consumption needs. In short, both voltage increase and decrease must be completed by transformers.
          During the process of transmitting electrical energy in power systems, voltage and power will inevitably occur. When transmitting the same power, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square the voltage. What is the function of power transformers, by increasing the voltage using transformers, the power transmission loss is reduced. A transformer consists of two or more wound on the same iron core. The coils are interconnected through an alternating magnetic field and operate according to the principle of electromagnetic induction. The installation location of the transformer be convenient for operation, maintenance, and transportation, while also being safe and reliable. When using a transformer, it is necessary to reasonably select the rated capacity of transformer. When a transformer operates under no-load conditions, it requires a large amount of reactive power. This reactive power must be supplied by the power system .
