By providing a plurality of 10M and connecting these units in series, it is possible to make the maintenance of a high-voltage transformer small and lightweight, and to reliably insulate the high-voltage transformer.

That is, since SF6 gas is used as compared with the conventional solid insulation method using epoxy resin and the insulation method using insulating oil, the weight can be reduced.
Maintenance and inspection can be facilitated, and since SF6 gas penetrates between the conductors of the secondary coil, corona discharge that tends to occur between the conductors of the secondary coil can be prevented. The secondary coil can be reliably insulated.

It is possible to change the states such as the pressure of the SF6 gas for each of the containers 9a, ..., 9M.

In the first embodiment and the embodiments described later, the object to be insulated by the container is limited to the secondary coil of the high voltage transformer, because the voltage of the current supplied to the primary coil is This is because it can be sufficiently insulated even in normal atmosphere (air), and it is only the secondary coil that requires measures against high voltage.

Moreover, since the high frequency current is supplied to the primary coil, there is a problem of heat generation. Since SF6 gas, which has a smaller specific heat than epoxy resin or insulating oil, is used, the entire high voltage transformer is used. When insulated with SF6 gas, it is necessary to take measures against heat generation in the primary coil. Therefore, in the present invention, only the secondary coil is limited to insulation with SF6 gas.

Although SF6 gas is described as the insulating gas in the first embodiment and the embodiments described later, the present invention is not limited to this, and any gas having excellent insulating properties can be used. It can be used.

In the second embodiment having such a structure,
The secondary coil of the high-voltage transformer is housed in a container formed of a metal material, and SF6 gas is sealed therein. The high-frequency current supplied to the primary coils 4a and 4b changes the magnetic flux generated in the cores 5a and 5b, and a high voltage is generated in the secondary coils. On the other hand, in the vicinity of the opening of the container through which the cores 5a and 5b pass,
An open circuit is formed from the cuts 22 and 23 filled with the epoxy resin, and an induced current does not flow.

As described above, according to the second embodiment, the same effect as that of the first embodiment can be obtained, and since the container formed of the metal material is used, an extremely high voltage is required. In this case, the pressure of the SF6 gas can be made sufficiently high, and since only the secondary coil is housed, the induced current generated in the portion where the core of the container formed of the metal material penetrates is It is blocked and prevented by the break filled with the epoxy resin. Therefore, the insulating property of the container formed of a metal material can be ensured.

A third embodiment of the present invention will be described with reference to FIGS. 4 and 5. In this third embodiment, an X-ray high voltage device composed of five units will be described.

FIG. 4 shows five containers 31a, 31b, 31c, 31d and 31e which respectively constitute five units.

The potential difference between the output terminals of 5 is α [V], which is the same as
When the outputs of 5 secondary coils are connected in series, X
A voltage of 5α is applied to the filament tube 36.

Since each of the containers 31a to 31e is connected to the ground, the output voltage from each of the containers 31a to 31e is α when the container 31e is in consideration of the ground reference.
[V], the container 31d is 2α [V], the container 31c
Is 3α [V], the container 31b is 4α [V], and the container 31a is 5α [V].

Therefore, the dielectric strength of the containers 31a to 3a is also high.
The withstand voltage property of the insulation of the SF6 gas must be adjusted so as to correspond to 5α, 4α, 3α, 2α, and α [V] for each 1e. That is, the pressure of the SF6 gas in the container 31a is E> the pressure of the SF6 gas in the container 31b is D> the container 3
The pressure of the SF6 gas in 1c is C> SF6 in the container 31d.
Gas pressure is B> SF6 gas pressure in the container 31a is A
Then, the relationship is E>D>C>B> A.

Even if the SF6 gas has a low pressure, the X-ray tube 3
The pressure of the SF6 gas in all the containers 31a to 31e can be made the same if they can be sufficiently insulated against the voltage 5α [V] applied to 6. Further, even if the SF6 gas can be sufficiently insulated against the voltage 5α [V] applied to the X-ray tube 36 even if the SF6 gas is at atmospheric pressure (no pressure applied), the pressure in the containers 31a to 31e can be made atmospheric pressure. good.

For example, the containers 31a and 31b can be formed of a metal material, and the containers 31c, 31d and 31e can be formed of a plastic material, so that the overall structure can be made light.

Further, each of the containers 31a to 31e is connected to the S from the gas cylinder 34 via the regulators 33a to 33e.
Since the F6 gas is constantly supplied, the pressure in the containers 31a to 31e can be kept constant at all times.

Therefore, it is not necessary to consider the pressure (internal pressure) of the SF6 gas in the container for the rigidity of the container 41.

As described above, according to the fourth embodiment, the same effect as that of the first embodiment can be obtained, and the container 41 is housed in the metal chassis 42 so that the gas in the metal chassis 42 can be protected. By setting the pressure to be the same as the pressure of the SF6 gas in the container 41, the SF in the container 41 is
Even if the pressure of the 6 gas is extremely high, it is not necessary to increase the rigidity of the container 41, and the container 41 can be made of, for example, a plastic material having high insulation and airtightness.

A fifth embodiment of the present invention will be described with reference to FIG. FIG. 7 is a cross-sectional view showing a container 51 that houses the secondary coil (not shown) of the high-voltage transformer and encloses SF6 gas.
