Description of the drawings
The further features and advantages of the present invention are made apparent from from the elaboration below according to schematic diagram to multiple embodiments.
Wherein：
Fig. 1 illustrates the circuit diagram of the X-ray maker according to prior art,
Fig. 2 illustrates the cross section of the container with conductive thin film,
Fig. 3 illustrates the cross section of another container with conductive thin film,
Fig. 4 illustrates the cross section of another container with conductive thin film,
Fig. 5 illustrates the cross section of another container with conductive thin film.
Specific embodiment
Fig. 2 is illustrated in cross-section container 8, and the container is also referred to as cylinder or tank, exist in container 8 electrical components 13,
Such as high-voltage components, the electrical components are stored in the liquid 14, such as insulating oil of electric insulation.In order to balance by electricity
The expansion of liquid 14 when component 13 is heated, container 8 with the pressure equaliser in the form of elasticity, conductive thin film 10,
The pressure equaliser forms air chamber 11 or air-gap with chamber wall 9.Pressure in air chamber 11 is equal to and surrounds container 8
The pressure of air 15.Thin film 10 is therefore, it is possible to moving along direction 12 and the thus pressure oscillation of the appearance of balancing liquid 14.
Chamber wall 9 is in electrically（=ground potential）Thin film 10 that is upper and being thus connected with chamber wall 9 is also such.Thin film
10 by resistance to mineral oil elastomer, such as rubber（Nitrile rubber, EPDM, IIR, SBE）Or silicones are constituted.Conductive thin film 10
For affecting/controlling electric field, thus can reduce with the spacing of electroactive component 13.Conductive thin film 10 can be with different classes
Type is manufactured, but must remain mechanical flexibility, does not allow to peel off or formed fold and must when running at all temperatures
Must be tolerance relative to mineral oil.
Thin film 10 for example has conductive plastic matrix, comprising conductive granule, such as graphite, white carbon black, SiC or metal
The line of grain, one side ground or two-sided with conductive surface, or integrated electrically conducting, fiber or band.The electrical conductivity of thin film 10 should
More than per meter of 1 Siemens.
Below, the result of computer sim- ulation is described.It is assumed that electrical components 13, such as high-voltage generator or X-ray tube are in height
Piezoelectric position（About 75kV）On.If thin film 10 is insulation, then in the balance space of air filling, i.e., electric field can enter into
Enter in air chamber 11.Spacing between electrical components 13 and thin film 10 may be too small so that draws in air chamber 11 big
In the maximum field strength of 4kV/mm.This can cause electric discharge, because the intrinsic conductivity of air is 2.4kV/mm.
But if thin film 10 container 8 it is equivalently-sized in the case of be conductive, i.e., electrical conductivity significantly greater than insulate
The electrical conductivity of liquid 14, and thin film 10 is via 8 good earth of container, then air chamber 11（I.e. using the space of air filling）
Keep without electric field.But, the field intensity increase in the liquid 14 above thin film 10.However, because liquid 14 is with than air
The considerably higher electrical stability in chamber 11, so electric discharge will not be occurred due to too high electric field.
Fig. 3 is shown in section another embodiment of the container 8 of the liquid 14 with electric insulation, at electrical components 13
In the liquid.Container 8 is grounded.Conductive thin film 10 form the side of chamber wall 9 so that formed liquid 14 and air 15 it
Between separate layer.When liquid 14 expands, thin film 10 can be along 12 outside arching of direction.
Fig. 4 is shown in section the flexible program of the embodiment according to Fig. 3.Container 8 has in the liquid 14 of electric insulation
There are electrical components 13.Chamber wall 9 is grounded.A part for the chamber wall 9 of bottom is formed by conductive thin film 10, and the thin film is
Separate layer between liquid 14 and air 15.Thin film 10 can be moved along direction 12 in the change in volume of liquid 14.
Fig. 5 is shown in section another embodiment with the container 8 in internal electrical components 13, the electricity
Learn component to be surrounded by the liquid 14 being electrically insulated.Chamber wall 9 is grounded.Pressure equaliser is by forming the bellows form of air chamber 11
Conduction thin film 10 being formed.Air chamber 11 is with the connection 14 of the tubulose of the air 15 for surrounding container 8 and then can be with
The UNICOM in the way of the case of UNICOM of air 15（Pressure i.e. in air chamber remains identical with the external pressure of air）.
All containers described in Fig. 2 to Fig. 5 can be used in construction X-ray maker and control X-ray to produce
The high pressure of irradiator, but also can be used in constructing integrated tank（Eintank）, the integrated tank accommodates the structure for producing high pressure
Part and x-ray radiator.
Worked in the way of the control of field and affect electric field and position according to the thin film 10 of the conduction of the container of Fig. 2 to Fig. 5
In the parasitic capacitance of neighbouring electrical components 13.This targetedly can be used for constructing and design high-voltage generator.Here,
The change of shape of the necessary viewing film 10 of run duration.
Additionally, for the loss of the high-voltage diode required for rectification in effect of parasitic capacitance high-voltage generator.If high
Pressure maker operation, then the high-voltage generator is heated up strongly so that deformation of thin membrane.Therefore, by big with the change of diode
Spacing, the loss that produces on the diode reduces so that high-voltage generator is heated up smaller.Meanwhile, the electricity of iknsulating liquid
Stability is reduced with the rising of temperature, but this obtains further through additional spacing and is compensated for.
Although the present invention is at large explained and described by embodiment, the present invention is not only restricted to disclosed showing
Example and other degeneration scheme can be therefrom derived by those skilled in the art, without deviating from protection scope of the present invention.
