The high-frequency transformer is a power transformer with a working frequency exceeding the intermediate frequency (10 kHz). It is mainly used for high-frequency switching power supply transformers in high-frequency switching power supplies, and also for high-frequency inverters in high-frequency inverter power supplies and high-frequency inverter welding machines. Variable power transformer. Why do high-frequency transformers have to be led out with leads?

It is convenient to use the plug-in power supply plug-in itself, but there are three disadvantages:

First, the output current is large, the secondary wire diameter, if it is easy to PIN 缠 with its own wire entanglement, the solder is easy to short-circuit, and it is easy to be higher than the skeleton fulcrum after soldering;

Second, the difficulty of the column will increase;

Third, the creepage distance between the secondary and the magnetic core is not enough, and additional insulation measures need to be added.

The lead-out is generally secondary. In order to increase the safety distance between the primary, if the foot is directly hung, it is difficult for the primary and secondary to meet the high pressure requirement! From the operational point of view, it is convenient to do flying lines!

In the development of products, in order to achieve small size or low height, in order to save space, the transformer can not use products with larger volume or skeleton to meet the requirements of safety regulations. Due to the limitation of space and skeleton itself, safety is allowed. Make the flying line longer distance to meet the safety distance requirements.
