Also, the X-ray generator 200 may include a high-voltage circuit for supplying energy for generating X-rays to the X-ray tube. The high-voltage circuit generates a high-pressure DC voltage and supplies it to the X-ray tube (not shown).

The X-ray tube (not shown) generates a lot of heat in the process of generating X-rays by using a high-voltage current as described above. The generated heat is absorbed by the insulating oil 500 so that the X-ray tube (not shown) can be cooled.

However, the insulating oil 500 may expand in volume due to heat absorbed in this process.

The cover 400 may be perforated so that a portion of the other surface is exposed. As shown in FIG. 2 , the cover 400 may be perforated to form a hole 410 penetrating the central portion of the cover 400 .

As shown in FIG. 2 , the other surface of the membrane 300 may be exposed to the outside of the tank through the hole 410 .

Through the hole 410 formed in the cover 400 as described above, the membrane 300 may be inflated by thermal expansion. Accordingly, it is possible to relieve the pressure, and it is possible to prevent the insulating oil from leaking through the gap between the membrane 300 and the case 100 or from damage to the tank.

The film 300 may include a first film 310 made of an elastic material that seals the opening of the case 100 . The elastic material may be a material having elasticity, such as rubber. More preferably, it may be a silicone resin.

The film 300 may include a second film 320 of a fiber material formed between the first film 310 and the cover 400 to limit deformation of the first film 310 . . The second layer 320 may be insulating paper. Insulation paper refers to paper widely used for various electric devices such as electric wires and capacitors because electricity does not pass through it.

The second film 320 has less elasticity than the first film 330 but is formed thinner to prevent excessive local deformation of the first film 310 .

In contrast, the film 300 is dispersed over a wider area to exhibit the effect of swelling. This structure prevents the leakage of the insulating oil 500 due to the concentration of pressure on only a portion of the plurality of fasteners 600 , and at the same time exerts an effect of effectively protecting the inside of the tank from external impact.

In addition, the rib 430 may have an appropriate elastic force. Accordingly, it is appropriately deformed according to the thermal expansion of the insulating oil 500 and returns to its original position upon cooling, thereby contributing to maintaining an appropriate pressure inside the tank.
