随着铁路跨越式发展的深入推进,铁路运输向着高速、重载、高密度方向发展,信号设备用修矛盾日益突出,电务原有的维修方式已不能适应铁路运输发展的需要,实施“天窗修”已经成为提高信号设备质量、确保运输安全的必由之路。通过近几年的实践,电务系统“天窗修”已逐渐走向正常运转轨道,信号设备运用质量得到了较大提高,一定程度上缓解了用修矛盾,基本实现了“行车不施工,施工不行车”的目标。然而,作为铁路行车设备维修方式的重大改革,“天窗修”在实施过程中还存在一些不足和问题。
With the further development of the railway by leaps and bounds, the railway transportation has been developing towards high-speed, heavy-load and high-density areas. The contradiction between the repair of signal equipment and the equipment has become increasingly prominent. The original maintenance methods of the electric power can no longer meet the needs of the development of railway transportation. Repair “has become the only way to improve the quality of signal equipment to ensure the safety of transport. Through the practice in recent years, the ”skylight repair“ of the electricity service system has been gradually moving towards the normal operation track, the quality of the signal equipment has been greatly improved, and the contradiction between the repair and the repair has been alleviated to a certain extent. The ”no driving construction and no construction Driving "goal. However, as a major reform of the maintenance of railway traffic equipment, there are still some shortcomings and problems in the implementation of Skylight Repair.
