Description
Technical Field
[0001] The utility model belongs to the technical field of transformers, and particularly relates to a waterproof high-frequency transformer structure. Background Art
[0002] A high-frequency transformer is a power transformer whose operating frequency exceeds the medium frequency. It is a device that converts AC voltage, current and impedance when working. When AC current flows through the primary coil, AC magnetic flux is generated in the iron core, inducing voltage in the secondary coil. It is mainly used as a high-frequency switching power supply transformer in high-frequency switching power supplies, and is also used as a high-frequency inverter power supply transformer in high-frequency inverter power supplies and high-frequency inverter welding machines.
[0003] Existing high-frequency transformers usually need to be used outdoors, and most of them only use a simple shell to protect the high-frequency transformer from rain. Since the high-frequency transformer needs to dissipate heat when in use, it is necessary to open multiple heat dissipation holes on the shell. This method will cause rain to be blown into the shell by the wind, reducing the waterproof effect, thereby causing a certain impact on the high-frequency transformer and easily causing damage. Therefore, we propose a waterproof high-frequency transformer structure. Utility Model Content
