100 kV 重频气体开关初步研究及应用
Investigation and application of 100 kV repetitive gas switches
摘要
Abstract
The tri-electrode gas switch and two-electrode rail-gap switch were designed.Experiments for breakdown-voltage and repetitive operation of these switches were done in different gas pressure and gap conditions.The results show the relation be-tween breakdown-voltage and gas pressure is linear.Breakdown-voltage of two-electrode rail-gap switch with 8 mm gap can be ad-justed from 90 to 125 kV at gas pressure 0.1 to 0.2 MPa.Operating voltage of trigger switch with 7 mm gap can be adjusted from 40 to 95 kV.Repetitive operation rate of these switches was up to 20 Hz with 20 kA current.Based on these switches,an 8-stage compact Marx generator was setup.Multi-pulse output with 5 or 10 Hz repetitive rate was gained in experiments.The output peak power was about 7 GW for 5 Hz,and 3.5 GW for 10 Hz with pulse width (FWHM)of 1 50 ns.关键词
