With the development of inline explosive foil detonation/ignition technology,higher require-ments are put forward for its safety and reliability.High voltage switches are key components in this tech-nology,and the application environments of them are very demanding.Therefore,high voltage switches are required to have small resistance and inductance,high conductivity,long service life,high stability and reliability.The stability of the self-breakdown voltage and delay time of the cold cathode trigger tube,a commonly used high-voltage switch,directly affects the safety and reliability of the inline ignition technol-ogy.The working stability of the cold cathode trigger tube is studied by analyzing discharge mechanism,improving electrode surface state,optimizing aging scheme,and conducting experimental comparative a-nalysis.It is concluded that by means of electrochemical polishing to improve the electrode surface state and aging with low current and high current to stabilize the discharge characteristics,the stability of the self-breakdown voltage and delay time of the cold cathode trigger tube can be improved and the safety and reli-ability of the cold cathode trigger tube in inline explosive foil initiation/ignition technology are enhanced.
