HIGH-VOLTAGE GAS-ARC ISOLATION OF PLASMA ACCELERATOR ACTUATING MEDIUM SUPPLY TRACK (VERSIONS) Russian patent published in 2012 - IPC H05H1/54 F03H1/00 

FIELD: electricity.

SUBSTANCE: invention may be used in pneumatic tracks for delivery of various gaseous actuating media (AM) to plasma accelerators or engines on their basis, and also in technological sources of plasma used for ion-plasma treatment of surfaces of different materials in vacuum. In the high-voltage gas-arc isolation of plasma accelerator actuating medium supply, containing at least two insulators with channels for actuating medium passage, installed in the opening of actuating medium supply track and connected to each other by means of a spacer, the next along the actuating medium flow is the insulator with smaller area of cross section of the channel for passage of actuating medium in comparison with the previous one. In the second version of isolation the next along the actuating medium flow is the insulator with high hydraulic resistance compared to the previous one with the same dimension types in cross section of insulator channels with different curve relative to gas flow.

EFFECT: higher reliability of high-voltage gas-arc isolation, ends of which during operation have high potential difference, functioning in wide range of gaseous actuating medium consumption and higher thermal effects, reduction of hydraulic losses of AM flow and labour intensiveness of manufacturing.
