一、建立动态检测标准的必要性我国铁路正沿着“尽快以内燃、电力牵引取代蒸汽牵引,铁路的发展是以电力牵引为主”的技术政策迅速发展。到“八五”末期,我国电气化铁路已达9788km,占全路营业里程的19%,承担铁路运量比重为24.7%。随着“九五”规划的实施,电化铁路将大幅度增加,所占比重也会越来越大。 1.检测车发展概况我国电气化铁路初期采用停电检测,这种开“天窗”停电检测的方法,占用了铁路运输时间,不利于发挥电化铁路的优越性。随着技术的进步,逐步发展了间接带电检测工具,检测过程是通过人工日常巡查进行的,检测项目多,劳动强度大,效率不高。为了解决
I. The Necessity of Establishing a Dynamic Testing Standard Our railway is developing rapidly along with “as soon as possible internal combustion, electric traction instead of steam traction and railway development based on electric traction”. By the end of the “Eighth Five-Year Plan” period, China’s electrified railway has reached 9,788 km, accounting for 19% of the total business mileage and 24.7% of the total railway traffic. With the implementation of the Ninth Five-Year Plan, the number of Dianhua Railway will increase substantially and the proportion will also increase. 1. Overview of the development of testing vehicles China’s electrified railway early detection of blackouts, this open “skylights ” power outage detection method, taking up the railway transport time is not conducive to the superiority of electrified railway. With the progress of technology, the indirectly-charged detection tools have been gradually developed. The inspection process is conducted through routine manual inspections. The testing items are large, labor-intensive and inefficient. In order to solve
