Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a high-frequency pulse transformer with insulation and wear resistance. Background Technique

[0002] A pulse transformer is a broadband transformer. For a transformer used in communication, non-linear distortion is a very important index. Therefore, it is required that the transformer operates at the initial permeability of the magnetic core. As a result, even for a transformer with very low power like an input transformer, its size has to be quite large. In addition to considering the frequency characteristics of the transformer, how to reduce losses is also a matter of great concern. The unqualified product quality of many manufacturers is mainly reflected in the insulation treatment. Doing a good job in insulation is the top priority in the production of high-voltage transformers.

[0003] In the existing technology, when a high-frequency pulse transformer is under the action of high frequency and high voltage for a long time, extremely fine local micro-discharges will occur and cause a certain degree of carbonization. As the degree of carbonization accumulates, the internal insulation strength of the high-frequency pulse transformer will continuously decrease, and finally lead to discharge breakdown.

[0004] In view of the above problems, the utility model provides a high-frequency pulse transformer with insulation and wear resistance. Content of the Utility Model

Through the cooperation among the box body, the insulating sleeve, the arc-shaped ceramic sheet and the insulating tape, the insulation degree inside the high-frequency pulse transformer is significantly improved. At the same time, the sealing and heat insulation inside the high-frequency pulse transformer are also increased, which can better protect the high-frequency pulse transformer. Moreover, the moving plate can drive the arc-shaped ceramic sheet to make a reciprocating linear motion in the horizontal direction. After the high-frequency pulse transformer has been used for a period of time, the arc-shaped ceramic sheet can be taken out from between the copper coils for cleaning and replacement, greatly enhancing the durability of the high-frequency pulse transformer, effectively solving the problem that when the high-frequency pulse transformer is under the action of high frequency and high voltage for a long time, extremely fine local micro-discharges will occur and cause a certain degree of carbonization, increasing the service life of the high-frequency pulse transformer, and thus solving the problems in the background technique.

[0022] In order to solve the technical problem that in the existing technology, when the high-frequency pulse transformer is under the action of high-frequency high voltage for a long time, extremely fine local micro-discharges will occur and cause a certain degree of carbonization. As the degree of carbonization accumulates, the internal insulation strength of the high-frequency pulse transformer will continuously decrease, and finally lead to discharge breakdown. As Figures 1-5 shown, the following preferred technical solutions are provided:

An insulating sleeve 4 is sleeved on the outer surface of the copper coils 3. A number of uniformly distributed and symmetric arc-shaped ceramic pieces 5 are arranged on both sides of the iron cores 2 in the vertical direction. The arc-shaped ceramic pieces 5 are all located between the copper coils 3. A moving plate 7 is arranged outside the arc-shaped ceramic pieces 5.

Then manually move the two moving plates 7 in a straight line along the direction of the iron core 2 to drive the arc-shaped ceramic sheet 5 to insert between the copper coils 3, separating the copper coils 3 and increasing the insulation degree of the high-frequency pulse transformer. Subsequently, a multi-layer insulating tape 8 is wound outside the moving plate 7, which not only fixes the moving plate 7 but also further increases the insulation degree of the high-frequency pulse transformer. Finally, cover the cover plate 17 to prevent dust and debris from entering the interior of the box body 1. The purpose of this design is to significantly improve the insulation degree inside the high-frequency pulse transformer through the cooperation among the box body 1, the insulating sleeve 4, the arc-shaped ceramic sheet 5, and the insulating tape 8. At the same time, it also increases the sealing and heat insulation performance inside the high-frequency pulse transformer, enabling better protection of the high-frequency pulse transformer. Moreover, the moving plate 7 can drive the arc-shaped ceramic sheet 5 to perform a reciprocating linear motion in the horizontal direction. After the high-frequency pulse transformer has been used for a period of time, the arc-shaped ceramic sheet 5 can be taken out from between the copper coils 3 for cleaning and replacement, greatly enhancing the durability of the high-frequency pulse transformer and effectively solving the problem that the high-frequency pulse transformer will undergo extremely fine local micro-discharges and cause a certain degree of carbonization under the action of high frequency and high voltage for a long time, increasing the service life of the high-frequency pulse transformer.

Subsequently, multiple layers of insulating tapes 8 are wound outside the moving plate 7, which not only fixes the moving plate 7 but also increases the insulation degree of the high-frequency pulse transformer again. Finally, the cover plate 17 is covered to prevent dust and sundries from entering the interior of the box body 1. The purpose of this design is that through the cooperation between the box body 1, the insulating sleeve 4, the arc-shaped ceramic sheet 5, and the insulating tape 8, the insulation degree inside the high-frequency pulse transformer is significantly improved. At the same time, the sealing and heat insulation performance inside the high-frequency pulse transformer are also increased, which can better protect the high-frequency pulse transformer. Moreover, the moving plate 7 can drive the arc-shaped ceramic sheet 5 to perform reciprocating linear motion in the horizontal direction. After the high-frequency pulse transformer has been used for a period of time, the arc-shaped ceramic sheet 5 can be taken out from between the copper coils 3 for cleaning and replacement, which greatly enhances the durability of the high-frequency pulse transformer and effectively solves the problem that the high-frequency pulse transformer will generate extremely fine local micro-discharges and cause a certain degree of carbonization under the action of high frequency and high voltage for a long time, increasing the service life of the high-frequency pulse transformer.
