Description

[Technical field]

[0001] The present invention relates to high voltage x-ray tanks, and more particularly to high voltage x-ray tanks including reduced size and weight shielding structures. [Background technology]

[0002] 2. Description of the Related Art In general, X-ray generators are widely used in a variety of testing or diagnostic devices, such as for medical diagnosis, non-destructive testing, or chemical analysis.

[0003] On the other hand, high voltage is required to generate X-rays, and conventionally, insulation techniques using insulating oil, insulating gas, or molding techniques have been used to ensure electrical insulation (see Figure 1).

[0004] Insulation techniques using molding techniques have the advantage of being able to ensure insulation even in small sizes, but they have the problem that many voids are formed during molding, reducing insulation efficiency.

[0005] Furthermore, when using equipment that uses X-rays, it is extremely important to make efforts to block X-rays, which are harmful to the human body. Currently, the most commonly used shielding material in manufacturing small X-ray tubes is lead, which is easy to process and can be made into thin sheets. However, lead is a heavy metal, which causes problems such as environmental pollution and is harmful to the human body.

[0006] Meanwhile, in the case of metals with high specific gravity such as tungsten, which have been proposed as a substitute for lead, there is a problem that electrical isolation is not easy in a structure that must be insulated due to the conductive properties of tungsten. Therefore, there is a problem that the size and weight of the X-ray generator increases due to the construction of an insulating tank (berth) for insulating the X-ray tube and a shielding material that covers the outside of the insulating tank.

[0007] Therefore, there is a need for a technology that can solve the problems of the conventional technology. [Prior art documents] [Patent documents]
