摘　　要：通过遥供音频无绝缘轨道电路(FTGS)对故障数据的提取分析,以及轨电位分布理论及对信号设备影响的理论研究,确定放大滤波板故障与轨电位异常相关。经过现场测试验证,轨电位升高是放大滤波板故障的原因之一,轨电位升高导致放大滤波板输出电压下降,放大滤波板的输出电容温度升高,最终导致放大滤波板的输出电容疲劳损坏。Through verification of field test,increasing of rail potential is one of the fault reason of Amplification and Filter board,increasing of rail potential will lead to decreasing of the output voltage of Amplification and Filter board,increasing of the temperature of output capacitance of Amplification and Filter board,finally fatigue failure of the output capacitance of Amplification and Filter board will be occured.

关 键 词：遥供音频无绝缘轨道电路 放大滤波板 轨电位 输出电容
