Research on Mechanisms of Lightning Hazards and Lightning Protection Measures for ZPW-2000A Track Circuits
This paper elaborates on the hazard mechanisms of different types of lightning,such as direct lightning,electrostatic induction lightning,and electromagnetic induction lightning.Based on on-site investigation and laboratory testing,this paper analyzes the pathways of lightning intrusion into ZPW-2000A track circuits,comprehensively analyzes the hazard mechanisms and intrusion pathways,formulates corresponding horizontal and vertical lightning protection measures,and explains the lightning protection characteristics such as"leakage","resistance",and"suspension".
