| Zusammenfassung | Microdischarges in metal vapours are important due to being a source of ignition in a flammable gas during the contact opening. Accurate prediction of processes in microdischarges is of particular interest. In this work, a unified one-dimensional model is applied to describe microdischarges in Zn vapour. The model comprises general species equations for electrons, ions, and atoms, the Poisson equation for the electric potential, and the heat transfer equation for the gas and the electrodes. The electron current density caused by thermo-field electron emission from the cathode is obtained using the transfer matrix method. Results are calculated for gap lengths in the range 60-160 μm under a constant current of 60 mA. The model is validated by comparing the results to electrical measurements delivering the voltage-length dependence, and spectroscopic measurements. The model is capable of predicting the linear increase of the burning voltage as a function of the discharge length during the contact opening. Furthermore, it qualitatively reproduces the spatial structure of the discharge and the emission spectrum. |
