Pulsed power technology is one of the technological foundations in high and new technology research, which has extremely broad development and application prospect. Gas switch is one of the key elements in pulsed-power devices, and electrode erosion is a key restrictive factor in high-power gas switch development and application. According to one dimensional equation of heat conduction and thermal equilibrium equation near the electrode surface, this paper researches electrode heat conduction mechanism, calculates electrode erosion heat fluxes and their peak powers caused under different discharge conditions. Calculation results indicate that arc joule heat is the main reason of electrode erosion when discharge current is not too high.
