Description

technical field [0001] The invention relates to a rotary electrode gas spark gap switch, which belongs to the field of pulse switch devices. Background technique [0002] In high power pulse technology, the gas spark gap switch plays an important role. There are two types of traditional spark gap switches: two-electrode switches and three-electrode switches. The repetition frequency characteristic is an important parameter of the gas spark gap switch, and the repetition frequency operation characteristic is related to various parameters, mainly related to the ionization recovery time of the gas. In order to increase the repeated operation frequency of the switch, it is often carried out by means of pneumatic circulation, but the switch with this structure is very bulky and suitable for large instruments and equipment. In response to the development needs of miniaturized pulse power technology in the future, it has become a trend to study miniaturized high current and repet...
