Magnetic core structure of high-frequency transformer

Abstract

The invention discloses a magnetic core structure of a high-frequency transformer, which comprises a magnetic core, wherein the side surface of the magnetic core is fixedly connected with a winding wire; a supporting rod is arranged at the top of the magnetic core in a penetrating mode; the top of the supporting rod is fixedly connected with a magnetic block; the side surface of a clamping rod isin engaged connection with a ratchet wheel; the surface of an inner wheel of the ratchet wheel is engaged with a push rod; the surface of the ratchet wheel is rotationally connected with a vertical toothed bar; the bottom of the vertical toothed bar is connected with a horizontal toothed bar in a meshed mode; a ventilation block is arranged on the side surface of the horizontal toothed rod in a penetrating mode; an exhaust fan is arranged in the horizontal toothed bar; a condenser is arranged on the right side of the exhaust fan; two ends of the horizontal toothed bar are fixedly connected with cutting rods; the side surface of the horizontal toothed bar is rotatably connected with a wire; and a fixing rod is fixedly connected in the magnetic core. According to the magnetic core structureof the high-frequency transformer, due to the fact that the magnetic core and the magnetic block are used in cooperation, the effect of compensating for part of leaked magnetic energy when the transformer works is achieved.

Description

technical field [0001] The invention relates to the technical field of high-frequency transformers, in particular to a magnetic core structure of a high-frequency transformer. Background technique [0002] High-frequency transformer is a power transformer whose operating frequency exceeds the intermediate frequency. It is mainly used as a high-frequency switching power transformer in high-frequency switching power supplies, and also used as a high-frequency inverter power transformer in high-frequency inverter power supplies and high-frequency inverter welding machines. According to the working frequency, it can be divided into several grades: 10kHz-50kHz, 50kHz-100kHz, 100kHz-500kHz, 500kHz-1MHz, and above 1MHz. [0003] During the working process of the transformer, since there is a certain gap between the coils wound on the magnetic core, a small electromagnet is formed between the gaps, which has its own magnetic induction line and is closed, so it will produce a differe...
