摘要：

This paper summarizes an experimental study of the multi-gap switch for fast linear transformer driver. The self-breakdown voltage testing has been conducted and the relation between self-breakdown voltage and gas pressure was obtained when the switch was filled with dry-air. As the pressure changed from 0 to 0.15 MPa, the self-breakdown voltage increased from 80 kV to 200 kV. An experimental study has been carried out on the triggering feature and discharge distribution property, and the uniform discharge distribution has been acquired after 5000 shots, which can prolong the life of the switch. The switch filled with 0.15 MPa dry-air had 34.4 ns delay with 1.6 ns jitter operating at 78.5% of self-breakdown voltage and trigger voltage of 70kV. The switch is very simple in structure and assembly, and its assembly precision is ameliorated observably.
