Dry-type transformer is an important power equipment, and its function has a lot to do with many functions of dry-type transformer. The production process of Dry-type single phase transformer is more, and there are many production processes for Dry-type single phase transformer, today we will discuss with you what is the relevant production process of Dry-type single phase transformer. Let's learn more about it:
Thread cutting:
This process is to disassemble the rolled enameled wire with a fixture, cut it into the specified length, pay attention to the storage of the enameled wire, and do not damage the enameled wire;
2. Winding the ring
The contents of this process are: the specified number of turns are wound on the specified magnetic ring with the specified enameled wire according to the work instructions.
Check that the magnetic ring is used correctly;
Check that the enameled wire should be used correctly;
The number of winding turns should be correct;
The needle used for threading should be polished and smooth by special personnel to prevent the needle tip from piercing the enameled thread during threading and forming high pressure defects during the finished product;
Loop wrapping quality requirements:
The winding is evenly distributed, and sometimes according to the requirements of the work instructions, a certain width of the gap is left. The uniformity of the winding distribution can greatly improve the leakage inductance and distributed capacitance of the final product;
The windings cannot overlap. Overlapping windings will bring two disadvantages, one is to increase the leakage inductance of the product; Second, the entire outer diameter of the semi-finished magnetic ring increases after the winding overlaps, which is not conducive to the placement of the magnetic ring when assembling the finished product;
Winding is not discounted. After the winding discount, it will bring at least three or more aspects of defects: after the winding discount, the enameled layer of the enameled wire is damaged, and the product will form a hidden danger of poor pressure resistance; The discounted enameled wire is easy to break;
After the enameled wire is discounted, the length is increased, and its DC resistance is also increased, and the DCR of products with stricter DC resistance requirements will be restricted.
Tightening of the winding. Loose winding will lead to an increase in the leakage inductance of the product;
The windings are not staggered, which is the same hazard as the windings do not overlap;
The length of the remaining leads should meet the requirements of the work instructions;
When the remaining line has a requirement to distinguish between long and short lines, it must be strictly distinguished, or supplemented by different colors to distinguish;
The storage of the magnetic ring should be placed in a small specified area to avoid damage and loss of the magnetic ring;
After winding the ring, the semi-finished products should be placed neatly, and the leads should not be curled.
3. Stranded wire (tap tap)
4. Magnetic ring dip
Due to the requirements of the process, some magnetic rings require pre-impregnation with insulating paint or silicone for magnetic ring protection to maintain certain characteristics of the product.
5. Baking process
In the production process of network Dry-type single phase transformer, there are many processes involved in the baking of products, in the baking process, there are the following places to pay attention to:
The above is the common dry-type transformer production process and a variety of production of the main methods for your reference, for the dry-type transformer production process and related processes you have any other questions and problems, please log in to our website for detailed understanding.
