The inventive insulation partitioned column contains the electrode section of the internal structure of distributed operating voltage and the external electrodes, the shielding section of the internal structure from the transverse electric field, with a cross-section in the shape of an oval or in the form of a composite figures formed by coupling at least two curvilinear shapes, with one of the peaks of the cross-cecena external electrodes with a greater curvature directed toward the end of the column with higher capacity and output, and the opposite vertex is directed inside the structure of the insulating columns. At least two sections of the internal structure under different potentials, are located opposite the total shielding outer electrode. This implementation of the columns increases dielectric strength and reliability of high-voltage patterns accelerator, supports the implementation of the external electrodes with small deviations from the calculated sizes, to reduce the periods. 5 Il. The invention relates to high voltage and accelerator technology, more specifically to high-voltage accelerators.Known high-voltage accelerators, in which the outer surface of the insulation partitioned columns made of electrodes (gradient rings of circular cross-section  However, the simplicity of the technology of manufacturing electrodes combined with the advent of high-tension electrostatic field at the surface of the column. Such performance columns often limits the maximum operating voltage, withstand insulating medium between the column and the tank or wall of the room.The closest constructive solution of the insulation partitioned columns with distributed between sections of a potential accelerator contains the outer electrode sections with a cross-section in the shape of an oval or in the form of a composite figures formed by coupling at least two curved shapes so that one vertex with a greater curvature directed toward the end of the column with higher capacity and output, and the opposite vertex is directed inside the structure of the insulating columns  In comparison with analogues with a circular cross section of the electrodes of the decree is ako at regular longitudinal section size 25-50 mm and the diameter of the column 1000-1300 mm exact performance of the estimated cross-sectional shape is difficult. Distortion is accompanied by increased field strength and, accordingly, decrease the breakdown voltage of the high voltage structure.The technical problem to be solved with the proposed solutions, are increasing transverse and longitudinal electric strength and reliability of high-voltage structure of the accelerator, as well as reducing the number, cost and weight of the outer electrode columns with complex cross-sectional shape.This task is solved in that the insulation partitioned column high-voltage accelerator with distributed between the sections work contains potential of the electrode section of the internal structure and the external electrodes, the shielding section of the internal structure from the transverse electric field, with a cross-section in the shape of an oval or in the form of a composite figures formed by coupling at least two curvilinear shapes, with one of the peaks of the cross-section of the outer electrodes with a greater curvature directed toward the end of the column with higher capacity and output, and the opposite vertex is directed inside the structure of the insulating columns; at least two sections of the internal structure, nachodaddiesm declare the result column is she has a high transverse and longitudinal dielectric strength and reliability in high-grade adjacent to the conductor, and low-grade adjacent to the Foundation, parts of columns. Screening of a number of sections one electrode greatly facilitates the manufacture of the outer electrode with small deviations from the calculated sizes, especially in the form of its cross section and flatness.The reliability of the device increases due to the fact that the use of the proposed invention the supporting column is not the weak link in isolation and the breakdown with columns, the most dangerous to the internal structure of the accelerator becomes unlikely.The technical result of the claimed column is also reducing the required number of electrodes complicated cross-section compared with the combined column  in two and more times. When the level reached the maximum operating voltage of the structure of the accelerator is not reduced.The technical result of the claimed column is also reducing the cost of manufacturing a smaller number of electrodes, as well as the reduction of the total mass of the outer elektrownie external electrodes along the surface of the column. By using the proposed invention facilitates the manufacture of the outer electrode complex cross-section of the sheet material, thereby decreasing the mass of the outer electrode.Section of the internal structure of the column (Fig. 1) contains the elements of the partitioned support insulator 1, and may also include elements of the divider 2, the equipotential frame around the insulator 3, one shielding electrode winding transformer accelerator, the elements of the rectifier, surge arresters and other Column supports in the space of the high-voltage electrode is a conductor 4 on a grounded base 5. The common electrode screen in an electrostatic accelerator  is located outside the column, in the transformer accelerator  the electrodes screens surround the internal structure of the columns inside and out, from the strong side of the field.Example. In Fig. 2-5 shows two high-voltage patterns accelerator EGP-8 and their corresponding distribution of field intensity on the surface of the electrodes facing to the tank. In this example, the tank diameter is 2.4 m, the potential of the conductor 5 MV. The structure includes a conductor 4, the outer electrodes 6 oval cross-section, the inner electrode frame 3 and the outer e the spine, normal to the axis and passing through the middle of the conductor 4.Fig. 3, 5 illustrate the technical effect obtained using the proposed column. Replacement of the outer electrodes of circular cross section on the common electrode for the three sections reduces the maximum tension on the string from 18.8 MV/m to 14.8 MV/m In comparison with a variant of the round cross section of the electrodes increase the breakdown voltage of the structure as a whole was 21% and the breakdown voltage is actually the column was increased by 30% So the column is more durable element of the structure and along with the increase of the operating voltage of the accelerator reduced the probability of breakdown with columns on the tank, the accelerator becomes more reliable.At this accelerator in accordance with the claimed invention instead of 42 of the outer electrodes with complex shape of the section you want to make 14 of the electrodes. On the accelerator EGP-15 reducing the cost of manufacture even more significantly, because instead of 72 required to produce electrode 24.To declare the column longitudinal dimension of the electrode in comparison with a variant of circular cross section is increased threefold. However, the greatest diameter 1130 mm it has a weight of about 6 kg, valid for the electrical strength of insulating columns, improves reliability of high-voltage structure of the accelerator that facilitates the execution of the cross-sectional shape and flatness of the electrodes with small deviations from the calculated sizes, significantly reduces the required number of electrodes of complex shape, reduces the mass of the electrodes and reduce the cost of manufacturing them at high electric strength of the structure of the column.Sources of information:
