아크집전의 효율성 향상을 위한 아크방전구조의 전자기적 해석

초록

Electric train was supplied with Catenary line for running in railway, which is the energy efficient and mass transportation system substituting to the internal combustion engine driven train. But it is necessary for contacts between the pantograph of train and catenary train line to maintain and manage with no defects and less arc. To prevent the harmful contact defects, the contactless current collection methods have been being investigated in many researchers for a long time. These include the capacitive coupling, electromagnetic coupling, inductive coupling. This paper has investigated the electrc field distibution of arc electrode configurations using COMSOL and calculated the thermionic emission and field emission current densities of arc discharge. This result will be useful to design the stable arc discharge configuration in the laboratory.
