A power transformer is a static electrical device that is used to convert a certain value of AC voltage (current) into another or several different values of voltage (current) with the same frequency. When the primary winding is energized with alternating current, an alternating magnetic flux is generated, and the alternating magnetic flux induces an alternating electromotive force in the secondar read more
The transformer is a device that can change the voltage made by the principle of electromagnetic induction. The transformer consists of an iron core and a coil. The transformer coil is divided into a primary coil and a secondary coil when the primary coil is energized with alternating current. The transformer core produces an alternating magnetic field. The secondary coil induces an alternating cu read more
Dry-type transformers are an important part of the power system, and their stability and safety have a great impact on the power system. When a dry-type transformer is short-circuited, the winding is affected by various forces such as compression and bending at the same time as it is affected by electricity. The resulting faults are sometimes hidden, making inspections and repairs difficult. There read more
The audio transformer can realize voltage converter conversion like a power transformer, and can also realize audio signal coupling. The main functions of audio transformers are as follows:1. Output transformer: It is used in audio equipment and playback equipment to transform the impedance in the circuit.2. Input transformer: The main function is when the sound signal is input, and it plays the r read more
In radio communications, broadcast television, and automatic control, it is used as a component of voltage amplification, power output and other circuits. The audio transformer has a uniform frequency response in the working frequency band, and its core is made of high-permeability materials. The primary and secondary windings are tightly coupled, so that almost all the magnetic flux passing throu read more
