Research on Lightning Protection Engineering of Traction Substation in Heavy Lightning Zone
Zhu Jiang · 2013
Research purposes:In recent years,people has begun to focus on the influence of lightning on the electrified railway.Especially the lighting activity in the heavy lightning areas brings the serious harm to the electrified railway in these areas.The lightning protection technology is an important for ensuring the reliability of the power supply system of the electrified railway.So the measures for the lightning protection must be strengthened and the lighting protection technology must be enhanced. Research conclusions:The three lines of defense should be built for the lighting protection for the substation to avoid the hit of the lighting strike to the substation devices,and the three level prevention should be built for avoiding the appearances of the failures of the low-voltage devices of the substation caused by the rising earth potential or the induced voltage and the induced current.Also the measures should be taken for the earthing system to make it in the good working state The lighting protection engineering for the substation should have the means mentioned above.
