The use of high voltage devices
High-voltage transformer is a common electronic device in electronic products, and it is an electromagnetic induction device. It is used to convert low-frequency and low-voltage into low-frequency and high-voltage when alternating current passes through the primary winding, and the transformer generates an alternating magnetic field. Through the induction of the alternating magnetic field, the secondary winding correspondingly generates an alternating magnetic field and generates an alternating electromotive force. The voltage of the secondary winding is related to the turns ratio of the secondary winding, that is, the voltage is proportional to the turns. The main function of high pressure is to convert low pressure into required high pressure, which is particularly important in the production process. The unqualified products of many manufacturers are mainly reflected in insulation treatment, and insulation is the most important thing in the production of high-voltage transformers.

Performance requirements of high voltage transformer
Temperature rise: High-voltage transformer runs continuously at ambient temperature below 40℃ and rated load, and the winding temperature rise measured by resistance method should not exceed 65℃. In this case, the temperature rise of the upper insulating oil measured by thermometer should not exceed 60℃, and the highest temperature rise of the winding should not exceed 80℃.
Short-circuit standard: the short-circuit tolerance of high-voltage transformer should meet ANS? The provisions of C57. 12
Overload standard: the transformer must be able to withstand the load exceeding the rating of the nameplate.
From the prices of some voltage devices listed above, we should be able to see that the prices of high-voltage transformers range from tens of yuan to tens of thousands of yuan. Due to the different places of use, the requirements for the internal components of the transformer are different, and the price is naturally different. Because this kind of high-voltage transformer is not widely used in life, there are very few manufacturers, and there are only a few in China. Then, if you need it, you might as well know the above article in order to give it a price position. If you want to know more. Please continue to pay attention to Tuba rabbit.
