| 摘要 |
The invention concerns a multichannel spark-gap (20) with multiple intervals designed in particular for use in pulsed high-power generators of the LTD family. The inventive spark-gap (22) comprises a sealed chamber (1), two discharge electrodes (3, 4) connected to electrical connecting means (15), and a number of intermediate electrodes (5, 6, 7) arranged uniformly inside the sealed chamber. One of the intermediate electrodes is called triggering electrode (5) and is connected to triggering means enabling the spark-gap to be fired. The triggering electrode (5) further comprises integral buses (8) enabling a gas to be distributed inside the chamber (1), so as to improve the voltage strength of the spark-gap. The inventive spark-gap (22) is characterized in that the negative discharge electrode (5) comprises a corona-effect device equipped with needles (14) whereof the geometry is adapted to compensate the differences in shape between the negative discharge electrode (4) and the immediately adjacent intermediate electrode (7) so as to ensure a homogenous distribution of the potentials inside the sealed chamber. |
