摘　　要：通过对25Hz相敏轨道电路和50Hz单轨条相敏轨道电路工程应用环境,以及在交叉渡线上电路构成机理进行分析,澄清25Hz相敏轨道电路在交叉渡线上设置单边绝缘和增设单边绝缘的必要性,以及取消50Hz单轨条相敏轨道电路在交叉渡线上单边绝缘的合理性。Through analyzing the engineering application environment of 25Hz phase detecting track circuit and 50Hz monorail phase detecting track circuit as well as the mechanism of circuit composition in intersecting crossover,It is clarified that it is necessary to set or add more mono-insulations of 25Hz phase detecting track circuit on intersecting crossover and it is rational to cancel the mono-insulation of 50Hz monorail phase detecting track circuit on intersecting crossover.

关 键 词：单轨条相敏轨道电路 交叉渡线 单边绝缘
