2017 年 1 月 . The result shows that:
the main offline arc band is for 30~100 MHz, within the range of the electromagnetic radiation amplitude
was is serious. Additional, due to the impact of the pantograph and slide plate, Arc radiation field was is
asymmetrical, the radiation field intensity in different directions were is different, the compartment front
and tail ends were are the main radiation direction.
Keywords: pantograph offline arc; electromagnetic noise; simulation; finite element analysis; radiation
