; The invention relates to electrophysics, and can be used to create capacitive energy storage devices in various electrophysical installations used for; To obtain a temperature-free plasma in: Pulsed light sources and electrotechnology.

 Controllable low-inductance arresters are known, containing two main and one control electrodes located on one side of the dielectric surface, having a thickness much less than the distance between the electrodes, a reverse current conductor located along the opposite side of the dielectric, divider voltage, the channel of the initiating impulse, connected by one pole to the control to the theme of the electrode.

Such a design of the discharge with electrodes extended along the surface of the dielectric in the direction perpendicular to the direction of the current makes it possible to form a multichannel sliding discharge that transforms into the plasma layer between the electrodes along the entire perimeter of the electrodes .. i

The discharge has a very low inductance and high erosion resistance due to a uniform current distribution along the entire perimeter of the electrodes. The arrester also has a maximum controllability range (from 0 to 3,) and high synchronization accuracy. The surge is stable and: it works well at operating voltages from 5 to 4 kV. Ojako if necessary to further increase the working voltage / or increase the stock of electrical strength in order to completely eliminate the potential; possible self-implementations (which are characteristic of practically weaving to known types of low-inductive point-to-point switches - armature), it is necessary to improve and change the design of days or days;

The aim of the invention is to eliminate the uncontrollable operation of the arrester at high voltages and to ensure high reliability of its operation.

j The goal is achieved by the fact that the current of the reverse current and the side of the dielectric surface adjacent to it is located adjacent to the latter, an insulated current-carrying screen, for example, of metal foil, a voltage divider connected to the intermediate potential point, and a channel: an initiating pulse connected by a different pole to the current-conducting screen, j JQ The drawing shows a controllable power supply (a inductive discharge. A pluggable discharge contains two axes of the BFBbix electrodes 1 and 2. and the control; intermittent Electrode 3, made as main, in the form of a strip extended to diele1: trika 4 is perpendicular to the direction of current, reverse current conductor 5. Channel (cable) b of the initiating (igniting) voltage pulse is connected ; Luce to electrode 3, and others to current mains: conductor 7, isolated from oo-i; ionic electrodes and conductor 5;; Between the main electrodes 1 and 2 Itt, a voltage divider 8 is connected, to the midpoint of which the conductor is connected ek1: yun; 7. Positions 9 and ilO denote, respectively, the power source and the load; I; capacitive storage switched by the calendar. The proposed detector works as follows. When charging basic types of labor by constant or pulsed voltage & voltage, the electric field; 85, the high-voltage electrode does not reach the critical: at which; the discharge begins on the hyphritia, due to the fact that it is separated from this electrode by a thin dielectric. The intermediate screen has an average nof-40 potential. i: However, when a control is applied, the pulse is. voltage across control electrode 3 i
