Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] Such as Figure 1A , 1B , 1C and 1D, a high-frequency transformer according to the present invention includes a magnetic iron core 1, and its upper primary winding 2 is configured to have basic low-voltage insulation therebetween, because they all operate at very close to zero volts, as Safety ground level GND.

[0022] The combination of the primary winding 2 and the magnetic core 1 is placed inside a hollow tube 8 inside an insulator 3 of th...

Abstract

The invention discloses a high-frequency transformer. The high-frequency transformer comprises an iron core, wherein a primary winding is arranged on the iron core, a secondary winding is arranged onthe iron core in an insulation mode, and the whole assembly is arranged and fixed in an insulator; the insulator is composed of two parts or two halves which are symmetric relative to the transverse vertical plane, each half is provided with a hollow pipe arranged in each half shell of the insulator, and an annular space between the outer walls of the pipes and the inner walls of the shells is arranged in the parts; the secondary winding or a high-voltage winding is arranged in the annular space; the insulator is provided with a groove in the outer shell and is located at the zero-volt level,and oil permeates into the secondary winding at the position. By means of the structure design, the transformer has the advantages that the transformer is combined with a single module, is more economical and efficient and reduces the weight and sizes of the assembly at the same time.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a high-frequency transformer. Background technique [0002] In the current stage of technology, designing and building a high voltage, high frequency, or high power transformer is not a problem. However, designing or building a voltage regulator that includes these three characteristics simultaneously represents a major challenge due to the conflicting requirements of the aforementioned characteristics. A high voltage transformer requires a high degree of insulation between its primary and secondary windings, a large distance separating the high and low voltage windings, or a large thickness of insulation. The separation between the windings reduces the magnetic coupling between them and thus increases the leakage reactance, limiting the output power. [0003] A high frequency transformer requires a very good coupling between the primary and secondary windings in order to ...
