Dry-type transformers are a key power-consuming machinery and equipment and high-power electrical appliances. Common dry-type transformers have a key influence on power engineering. The application of dry-type transformers means to grasp its efficiency. The efficiency of dry-type transformers is very important. The efficiency of dry-type transformers is constantly improving. So what are the ways to improve the efficiency of dry-type transformers? Come and learn about it with the editor of Dajuli Transformer.

Under a certain first stage of power, when the winding loss (copper loss) of the dry-type transformer is close to the iron loss, for example, copper loss/iron loss = 150% to 20% level, it cannot be ignored, and it should be fully considered Take steps to reduce copper losses. Since the power shouldered by the original winding and the secondary winding is similar, the copper loss of the original winding is taken in the scheme design to reduce the copper loss, which is conducive to simplifying the calculation process of the scheme design. Since the thermal conductivity is not easy to accurately determine, it is easy to simplify the calculation, and sometimes it is necessary to strongly recommend some standards and data statistics in advance according to the work experience.

It is easy to simplify the calculation. Different winding current strengths are strongly recommended for dry-type transformers with different powers. They are all essential, but not only limited to a certain current strength value, for example, 2A/mm2 ~ 3A /mm2. The methods required for the design of dry-type transformer solutions are not limited to this category, and various explorations should be allowed. The high efficiency of the use of dry-type transformers cannot depend on a single point. It should be comprehensively explored and fully considered according to the regulations of your application. If the dry-type transformer meets the relevant application standards, it can continue to be explored and improved. efficient method.

With the continuous development of the knowledge economy era and social and economic development, the high efficiency of dry-type transformers will be faster, and the requirements for high efficiency are getting higher and higher!
