In the process of transformer production, its various structures (including wire frame, casing, core) should be based on different needs, to choose different materials, different structural design for processing and production. Next, I will make a specific introduction to the details of each material selection.
Wire frame, can also be called skeleton, as the name suggests, in the low-frequency transformer plays a role in the coil support. According to the material of low-frequency transformers, we can categorize the material into thermoplastic, thermosetting two categories. Nylon, PET plastic and PBT plastic belongs to the thermoplastic materials, and thermosetting materials we often choose?PM Bakelite. After selecting a good material, it should be based on the design of the shape of the low-frequency transformer to make the wire frame, at this time the wire frame can be divided into cell, double-cell, drawer, sub-mother type and so on several kinds.
The core is one of the most important components of low-frequency transformers, now commonly used is silicon steel sheet. However, silicon steel sheet in accordance with different bases can be divided into many types, for example, according to the different production processes can be divided into calcined and non-calcined two kinds, if according to the different shapes can be divided into EI-type, ?C-type, mouth type? These kinds of. In accordance with other performance indicators of the transformer, the core can be selected so that the low-frequency transformer as a whole can work harmoniously. For example, in larger power transformers, we often use mouth type silicon steel sheet, because it has the advantages of good heat dissipation, good insulation, and short magnetic circuit. In addition, the combination of the above types of silicon steel sheet can also be obtained in different models, for example, two C-type can be composed of CD-type silicon steel sheet, and four C-type can be composed of ED-type silicon steel sheet. Coil type is generally metric system and the British system, in the two systems were used in millimeters (mm) and inches (inch) for the unit, respectively, marked its width and thickness.
There are many different types of bushings, and they are used for a wide range of purposes. And we are in the process of making low-frequency transformers commonly used bushings are Teflon, silicone rubber bushings, PVC bushings and so on. Teflon has the advantages of high temperature resistance, acid and alkali resistance, abrasion resistance, and is widely used in the electronic and mechanical industries. In addition to this, the size of the window area should be taken into account when making the low frequency transformer, and the window area should be at least larger than the cross-sectional area of the coil after it is wound around the core to ensure that insulating materials can be put into the low frequency transformer with the required coil.
On the low-frequency transformer remanufacturing process of the various components of the selection of materials on the introduction on this, I do not know whether you read after the low-frequency transformer has a more in-depth understanding. Of course, in the purchase of low-frequency transformers, there are many other factors to consider, only well thought out to ensure that the use of comfort.
