AI Technical Summary
When ignition experiments are conducted on cathodes on multiple existing cathode supports and corresponding simulated anodes, the ion discharges interfere with each other, resulting in reduced accuracy and reliability of the ignition test. This also makes it impossible to conduct ignition tests on multiple cathode supports simultaneously, thus reducing work efficiency.
A multi-station cathode simulation ignition device was designed. By applying high voltage to the simulated anode plate and applying heating voltage and contact electrode voltage to the cathode support, the cathodes of each station are separated from the simulated anode plate by a quartz partition to prevent mutual interference of ion discharge. Adjustment components and wiring mounting posts are used to achieve stable connection and power transmission between multiple cathodes and the simulated anode.
It improves the accuracy and reliability of ignition tests, allowing simultaneous ignition tests on cathodes and simulated anode plates on multiple cathode supports, thus increasing the efficiency of cathode ignition tests.
