Abstract

Abstract: 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".

Key words: lightning, direct lightning, induction lightning, horizontal protection, vertical protection, transfer coefficient

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。
