摘　　要：详细阐述不同雷电类型,例如直接雷、静电感应雷、电磁感应雷的危害机理。结合现场调查情况和实验室的测试情况,分析侵入ZPW-2000A轨道电路的途径,综合分析危害机理及侵入途径后,制定相应的横向、纵向防雷措施,并对“泄”“抗”“悬浮”等防雷特点进行阐述。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".

关 键 词：雷电 直击雷 感应雷 横向防护 纵向防护 转移系数
