Description

The invention relates to a pulse technique and can be widely used in experimental physics. Known rotating discharge containing coaxial electrodes with outlets, rotating in opposite directions dielectric discs with equidistant from the axis switching holes, placed between the electrodes and equipped with a moving mechanism 11. However, the scatter of these dischargers, due to the finite dimensions of the switching holes and the imperfect surface of the electrodes, is large. Closest to the present invention is a rotating glitter containing coaxially mounted fixed main electrodes, between which there is a fixed junction electrode made in the form of a disk, rotating dielectric discs with switching holes, installed between ignition and main electrodes, and a system of synchronized bicking connected to the specified ignition electrode L2J. The synchronization pszhyg system is implemented in the form of a rigidly gripping on the collector shaft, plates: JcpToporo electrical pairs are connected, and a brush to which are connected in series a storage capacitor and the primary winding of a pulse transformer, the secondary winding of which is connected between one of the main electrons and the ignition electrode. In the process of operation, if the aperture coincides with the protrusions of the electrodes, the synchronized peel-burning system forms an igniting pulse and the arrester trips. . When the gadget operates in a continuous mode, the brushes in the sync pulse shaping system are worn out, which leads to an increase in the frequency spread of the sync pulse shaping, and, consequently, the scatter trigger trigger. In addition, the frequency of triggering of the arrester is limited by the speed of rotation of the dielectric disks. The purpose of the invention is to increase the switching time and frequency and the stability of operation. This goal is achieved by the fact that in the rotation of the discharge generator containing coaxially mounted fixed main electrodes, between which is placed a fixed driving electrode in the form of a disk, rotating Dielectric disks with switching holes, installed between the igniting and main electrodes, and a synchronized ignition system connected to the ignition electrode, the rotation directions of the dielectric disks are chosen opposite, and the dielectric disks are made with additional These holes coincide when the switching holes coincide, and the synchronized ignition system is made in the form of two light guides, one of the ends of which are installed in these additional holes dielectric K (31X disks, and the second ends are located respectively opposite the light source and the light receiver connected To the input of the high-voltage pulse shaper, the output of which is connected to the ignition electrode. The drawing shows a schematic structural diagram of the proposed bit. The arrester contains coaxially arranged stationary annular main electrodes 1 and 2 and annular disk ignition electrode 3, rotating in opposite directions dielectric disks 4 and 5 with switched holes 6 and 7 and additional holes 8 and 9 in which one of the the ends of the optical fibers 10 and 11, opposite the second ends of which are located respectively the source 12 of the light and the receiver 13 of the light connected to the input of the shaper 14 high {.. voltage pulses, the output of which is connected to the ignition electrode 3. The dielectric disks 4 and 5 are associated with autonomous movement mechanisms 15 and 16. The discharge works as follows; The switching voltage is applied to the main electrodes 1 and 2.. The mechanisms 15 and 16 of the movement perform the rotation of the dielectric disov 4 and 5. When the additional holes 8 and 9 coincide, the light beam from the light source 12 enters through the light 10 and 11 to the light receiver 13, which generates an electrical sypnal. The shaper 14 high-voltage mpulsov amplifies the signal from the receiver-310 ka 13, i.e. converts into a FAST-BACKGROUND signal that reaches the ignition electrode 3. The output of the arrester triggers, i.e. the closure of the switching channel through the switching holes 6 and 7 simultaneously coinciding with the additional holes 8 and 9. The proposed discharge makes it possible to increase the operating life of the arrester by an order of magnitude, since the life of the electrical circuits. collector with rubbing brushes in the prototype. The reliability of the proposed grade is high,

6 so As with the rotation of dielectric disks from autonomous mechanisms of movement, the use of several systems of the same scheme is not required. The light link will minimize the disturbance of the switching of the arrester, since the light receiver can be positioned at a considerable distance from the source of interference and shielded. The trigger performance (stability) increases several times. Thus, under the same conditions, the accuracy of the crawl of the plates of the collector with the adjacent brushes is much less than the accuracy of the execution of additional holes.
