Description

A novel high-voltage rectifier bracket Technical Field

[0001] This invention belongs to the field of accelerator technology, specifically relating to a novel high-voltage rectifier support. Background Technology

[0002] The high voltage of several megavolts in the high-frequency high-voltage accelerator is generated by a high-frequency power generator, which is stepped up by a high-frequency transformer and then multiplied by a voltage doubler rectifier circuit to obtain a DC high voltage of several megavolts.

[0003] With the development of high-frequency high-voltage accelerator technology, the overall equipment with high-frequency high-voltage accelerators as key components in the application market has more and more functions, and at the same time, the requirements for size are also getting higher and higher. At present, high-voltage accelerators on the market are assembled manually by connecting hundreds or thousands of rectifier diodes in series. They are large in size, expensive, not only bulky, but also weigh hundreds of kilograms, which cannot be moved by manpower. At the same time, the quality is unreliable. If even one silicon particle is damaged, the entire rectifier element will be scrapped. Summary of the Invention

[0004] The purpose of this invention is to provide a novel high-voltage rectifier bracket with a simple structure and reasonable design in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A novel high-voltage rectifier support includes a base, on the top of which are mounted multiple columns. A top cover is mounted on the top of each column. A portion of the columns are externally snap-fitted with multiple first equalizing rings. The columns are divided into two equal parts. Another portion of the columns are externally snap-fitted with multiple second equalizing rings. The first and second equalizing rings are equally spaced vertically. Adjacent first and second equalizing rings are separated. A high-voltage diode is electrically connected between a first equalizing ring and a second equalizing ring located above it. Each column is composed of several support pillars, which are plugged into each other.

[0007] As a further optimization of the present invention, the top of the support column is provided with a plurality of insertion holes, and the bottom of the support column is provided with a plurality of insertion posts that cooperate with the insertion holes.

[0008] As a further optimization of the present invention, two first fixing holes are provided on the top surface of the support column at the topmost point of the column, and multiple second fixing holes are provided on the top of the top cover to cooperate with the first fixing holes. Bolts that cooperate with the first fixing holes are screwed into the multiple second fixing holes.

[0009] As a further optimization of the present invention, a slot is formed between each pair of adjacent pillars. The slot is composed of a first fixing slot and a second fixing slot opened on one side of the pillar. The first equalizing ring and the second equalizing ring are both snapped into the slot.

[0010] As a further optimization of the present invention, the top of the base is provided with a positioning hole for use with the plug-in post, and the plug-in post is inserted into the positioning hole and fixedly connected by sealant.

[0011] As a further optimization of the present invention, both the base and the top cover are annular structures, and the plurality of columns are annularly arranged between the base and the top cover.

[0012] As a further optimization of the present invention, the topmost support column is made of metal, while the remaining supports are made of PPS.

[0013] The beneficial effects of this invention are as follows: The modular design and easy assembly structure of this invention result in a significant reduction in the size of the accelerator and a substantial reduction in manufacturing costs, transforming the accelerator from an expensive piece of equipment into a common processing device. This plays a key role in the widespread application of accelerators. At the same time, it facilitates the replacement of damaged parts, avoids the scrapping of the entire rectifier element, improves resource utilization, and makes it more convenient for people to use.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] As shown in Figures 1-7:

[0024] A novel high-voltage rectifier bracket includes a base 1, with multiple columns 2 mounted on the top of the base 1. A top cover 3 is mounted on the top of all columns 2. Each column 2 is divided into two parts. One part of the column 2 has multiple first equalizing rings 4 externally snap-fitted to its exterior, while the other part of the column 2 has multiple second equalizing rings 5 ​​externally snap-fitted to its exterior. The first equalizing rings 4 and the second equalizing rings 5 ​​are arranged at equal intervals in the vertical direction. Adjacent first equalizing rings 4 and second equalizing rings 5 ​​are separated. The vertical distance between any two adjacent first equalizing rings 4 and any two adjacent second equalizing rings 5 ​​is 13mm, and the voltage between them is 100kV. Silicone oil is used for insulation, with a breakdown voltage of 40kV-100kV / mm. The first equalizing rings 4 and the second equalizing rings 5 ​​are made of oxygen-free copper. A high-voltage diode 6 is welded between each first equalizing ring 4 and the second equalizing ring 5 located above it. The input voltage during use is 200kV. The AC power supply is 00KHz (adjustable from 100-300KHz), divided into two lines. Each line is 100KV connected to a high-frequency electrode. The DC power is rectified by the coupling capacitor between the high-voltage diode 6 and the first equalizing ring 4 and the second equalizing ring 5. The column 2 is composed of several support pillars 21. Each pair of adjacent support pillars 21 is fixed by plugging in. The top support pillar 21 is made of metal, while the other support pillars 21 are made of PPS. The reason why the top support pillar 21 is made of metal is that the two layers at the top are at the same potential. The reason why the other support pillars 21 are made of PPS is that this material can be injection molded, and after molding, it has high hardness and strength, as well as good insulation performance. The top support pillar 21 and the top cover 3 are made of aluminum alloy, and the base 1 is made of SUS304 stainless steel. The top cover 3 and the base 1 form a limiting and fastening device to prevent the entire component from shifting and shaking. The support pillar 21 is formed by injection molding, and the integrated production avoids errors and facilitates the efficiency and convenience of assembly on the automated assembly line.

[0025] The top of the support column 21 has multiple insertion holes 22, and the bottom of the support column 21 has multiple insertion posts 23 that mate with the insertion holes 22. The top surface of the support column 21 at the very top of the column 21 has two first fixing holes 31, and the top of the top cover 3 has multiple second fixing holes 32 that mate with the first fixing holes 31. Bolts that mate with the first fixing holes 31 are screwed into each of the multiple second fixing holes 32. A slot 7 is formed between each pair of adjacent support columns 21. The slot 7 consists of a first fixing slot 71 and a second fixing slot 72 formed on one side of the support column 21. The first equalizing ring 4 and the second equalizing ring 5 are both snap-fitted into the slot 7; a slot 7 is formed between each pair of adjacent pillars 21, and the slot 7 is composed of a first fixing slot 71 and a second fixing slot 72 opened on one side of the pillar 21. The first equalizing ring 4 and the second equalizing ring 5 are both snap-fitted into the slot 7. The top of the base 1 is provided with a positioning hole 24 for use with the plug-in post 23. The plug-in post 23 is inserted into the positioning hole 24 and fixedly connected by sealant; the base 1 and the top cover 3 are both annular structures, and multiple pillars 2 are arranged annularly between the base 1 and the top cover 3.

[0026] When the high-voltage rectifier bracket needs to be disassembled during use, the bolts can be unscrewed from the first fixing hole 31 and the second fixing hole 32. After all the bolts have been unscrewed from the first fixing hole 31 and the second fixing hole 32, the top cover 3 can be directly removed from the top of the multiple columns 2. Since each pair of adjacent columns 21 is fixed by plugging, the multiple first equalizing rings 4 and multiple second equalizing rings 5 ​​are all locked in the slots 7. In this way, the columns 21, the first equalizing rings 4 and the second equalizing rings 5 ​​can be disassembled from top to bottom. This modular design and easy assembly structure not only reduces costs, but also facilitates the replacement of damaged parts, avoids the scrapping of the entire rectifier element, improves resource utilization, and makes it more convenient for people to use.

[0027] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
