The invention discloses a track insulation measuring instrument which comprises a track insulation measurer, a liquid crystal display screen is arranged on the surface of the track insulation measurer, and an instrument lifting belt buckle is fixedly arranged on the side surface of the lower end of the track insulation measurer. And a first access terminal and a second access terminal are fixedly mounted on the side surface of the upper end of the track insulation measurer. According to the track insulation measuring instrument, on-line detection and diagnosis of the insulation performance of the railway track can be achieved under the condition that railway track circuit equipment and railway track insulation are not disconnected, a voltage signal is injected into the railway track and a current signal is received at the same time by using an independent wire to be matched with an electrode pen; the influence of lead resistance and contact resistance on the measurement result is eliminated, the current of the railway track can be directly collected through the Rogowski coil, the influence of bypass resistance is avoided, and the purpose of accurately measuring the resistance value of the railway track insulation joint under the condition that the influence of other parallel bypass resistance of the railway track is avoided is achieved. Meanwhile, rapid and simple operation is realized, and the measurement efficiency is improved.

    本发明公开了一种轨道绝缘测量仪,包括轨道绝缘测量器,所述轨道绝缘测量器的表面设置有液晶显示屏,且轨道绝缘测量器的下端侧表面固定设置有仪表提带扣,所述轨道绝缘测量器的上端侧表面固定安装有第一接入端子和第二接入端子。该轨道绝缘测量仪,能够在不断开铁路轨道电路设备和铁路轨道绝缘的情况下,实现对铁路轨道绝缘性能的在线检测和诊断,通过使用单独的导线配合电极笔来向铁路轨道注入电压信号并同时接收电流信号,消除导线电阻和接触电阻对测量结果的影响,通过罗氏线圈可以直接采集该铁路轨道的电流,不受旁路电阻影响,达到避免受到铁路轨道其它并联旁路电阻的影响的情况下准确测量铁路轨道绝缘节的电阻值的目的,同时实现快速、简便的操作,提高测量效率。
