驼峰场信号电缆对地绝缘电阻的测试是一项非常重要的工作,如果电缆绝缘不良,将直接影响信号设备的正常使用。以往,信号工区都是使用兆欧表对电缆绝缘手动测试。由于现场电缆数量很多,手动测试效率低,劳动强度大,因此,迫切需要应用微机监测设备。铁科院通号所在最近开通的TBZKⅡ Hump ​​signal field to ground insulation resistance test is a very important task, if the cable insulation is poor, it will directly affect the normal use of signal equipment. In the past, signal work area is to use megohmmeter on the cable insulation manual test. As a large number of on-site cables, manual testing inefficient, labor-intensive, therefore, the urgent need to use computer monitoring equipment. The latest version of TBZKⅡ, where the ASTRI passes
