电气化铁路轨道电路绝缘电压测试法的研究

Study on Insulation Voltage of Track Circuit in Electrified Railway

目前,电气化铁路站内轨道电路区段大多采用机械绝缘进行分割,保证轨道电路正常工作,然而90%的绝缘无法目测判断性能是否良好。为此,提出电气化铁路轨道电路绝缘电压测试法,解决了传统方法的不足,有效地压缩轨道电路故障延时。

Currently, track circuit in most of electrified railway station adopts mechanical insula- tion to guarantee the normal working of track circuit. However, it is hard to determine whether the insulation is in good condition only by visual inspection in 90% cases. Therefore, we put for- ward a test method of insulation voltage of track circuit in electrified railway to solve the short- coming of traditional method and the delay due to track circuit fault can be reduced effectively.
