Many industrial equipment require the use of small power transformers. Do you know what the structure of this product is? In fact, its structure is composed of multiple parts. Let’s introduce it in detail below.


1. Iron core: The iron core is the core of the entire product. The main function of the iron core is to increase the magnetic flux density and reduce copper loss. The shapes of the iron core include square, round and rectangular, and the material is usually made of silicon steel sheets.

2. Coil: The coil is an indispensable part of the product, it can change the voltage into the required voltage. The coil is made of electrolytic copper wire and wound into coils with different numbers of turns and different specifications.

3. Insulating materials: Many parts of the product require insulating materials. Commonly used materials include cardboard, paper tubes, rubber, etc. The function of insulating materials is to isolate the current between various parts.

4. Terminal: The terminal is a bridge connecting the coil and the power supply. It connects the primary coil and the power input terminal, and connects the secondary coil and the output load terminal. The terminal is generally made of copper or aluminum and has good conductivity and resistance. Corrosive.

5. Skeleton: The skeleton is generally made of plastic, and some manufacturers also use plywood and bakelite fiberboard.


6. Radiator: The radiator is mainly used to dissipate heat and prevent product damage caused by overheating. There are many shapes of radiators, such as heat sinks, heat dissipation nets, etc.

In summary, the structure of a small power transformer consists of an iron core, a coil, an insulating material, a terminal, a radiator and a frame. Each component has its own role. Once a problem occurs in one component, it will affect the performance of the entire product. Performance and usage.
