Amazing small type R transformer, its unknown role!
Small transformers usually refer to power frequency small capacity single-phase transformers. Small single-phase transformers usually consist of a closed iron core and two turns of winding on the iron core, insulated from each other. This kind of small transformer is very common and widely used in our life. Let’s take a look at the small transformers that are often used and how they work.
Before understanding the working principle of a small transformer, let’s first understand what is the main function of a small transformer? In general, the functions of the transformer mainly include voltage conversion, impedance conversion, isolation, voltage stability and other functions. At present, due to the increase in customer demand, the core of the transformer is usually made of R core, which makes the performance of the transformer more stable and efficient. Next, let’s talk about how the transformer works properly. Transformers mainly use the principle of electromagnetic induction, the voltage AC side of the conversion to the same frequency of the other side of the voltage AC energy conversion. Two winding is set on the iron core, and one winding is connected to the power supply, also known as the original winding. The other connected load, which we call the secondary winding, when the original winding voltage is applied to produce a current, the established magnetic flux is closed along the core, respectively, and the potential is induced in the original winding.
Let’s see how the function of the small transformer is realized. Voltage conversion: When the AC voltage is increased at both ends of the primary winding resistance, the winding resistance will generate the main magnetic flux of the primary winding resistance exchange chain and the secondary winding resistance exchange chain in the iron core through the AC current. As long as the original turn ratio and the secondary winding resistance are changed, the voltage can be changed. Current conversion: Usually, when the transformer is working, the size of the secondary current mainly depends on the size of the load impedance, and the size of the primary current depends on its size. When a transformer changes the voltage, it can also change the current.
Generally, r small transformers are widely used in medical equipment, mining systems and equipment, mining underground lighting, airport navigation lighting, communication systems and tower equipment, instrumentation equipment, some precision instruments and equipment and other fields. With the development of society, more and more equipment will use r small transformers.
