GAS-FILLED SPARK GAP Russian patent published in 2003 - IPC

FIELD: gas engineering. SUBSTANCE: main spark gap is pre-ionized by corona discharge. Spark gap is provided with two additional electrodes in the form of hollow body of revolution intended to build up corona discharge for stabilizing initiation and development of discharge in main spark gap; each body of revolution has axial hole and is coaxially arranged and connected to one of main electrodes. Geometric dimensions of spark gap components are adequately chosen to ensure desired characteristics. EFFECT: enhanced breakdown voltage stability. 1 cl, 2 dwg
