PROJECT TITLE :
Design and construction of a ??100 kV gas switch for linear transformer drivers
During this paper, the planning, installation, and performance of a ±one hundred kV gas switch for linear-transformer-driver (LTD) are presented. LTD demands need gas switches that may be operated at a two hundred kV DC voltage, and require trigger jitter and inductance as little as doable. A field distortion switch has been designed primarily based on the L3 switch, the design criteria of switch electric field and trigger system are explained well. A two dimensional plasma model is developed to investigate the contribution of trigger system to the closing of gas switch. An experimental platform was engineered to check the self breakdown and triggered breakdown characteristics of the switch. When the switch is charged to ±100 kV and is triggered by a -one hundred twenty kV pulse with a thirty ns rise time, the delay time is seventy eight ns and the jitter is one.half dozen ns. A comparative check was done to research the perform of UV preionization gap, the check results shown that the UV preionization gap will scale back the switch delay time and jitter, it will effectively improve the trigger performance of the switch. Meanwhile, using the short-circuit discharge, the inductance and impedance were measured, the switch inductance is about thirty nH, and also the impedance is varied from 50mΩ to 30mΩ.
