摘　　要：介绍了铁路信号轨道电路第三轨效应的产生原因;分析了轨道电路设置纵向防雷器的原因和第三轨效应与纵向防雷器的关系;阐述轨道电路装设纵向防雷器后应不会产生第三轨效应。轨道电路室内设备应按规定装设纵向防雷器和横向防雷器。This article describes the causes of the third rail effect of railway track circuit, and analyzes the reasons for setting the Longitudinal Lightning protection devices and the relationship between the third rail effect and Longitudinal Lightning protection devices. It is pointed out that the track circuit with an installation of longitudinal Lightning protection devices will not cause the third rail effect. Indoor track circuit equipment should be required to install the longitudinal and transverse lightning protection devices.

关 键 词：轨道电路 第三轨效应 纵向防护
