摘　　要：在中压送配电系统中,由于干式变压器具有效率高、体积小、安装方便等优点,已被广泛应用于城市轨道交通供电系统中。然而,干式变压器的防尘性能较差,在工作过程中容易降低带电设备的绝缘性。因此,开展对干式变压器的运维检修工作尤为重要。基于此,针对干式变压器清扫与裂损检测组合工具在地铁牵引供电维护中的应用展开研究。充分利用有限的“天窗”时间保证维护检修结果的准确性,既提高了维护检修效率,又缩短了检修作业的停电时间,还减少了检修人员的工作量,确保了城市轨道交通电力供电系统的安全稳定运行。In medium voltage power transmission and distribution systems,dry-type transformers have been widely used in urban rail transit power supply systems due to their high efficiency,small size,and easy installation.However,the dust prevention performance of dry-type transformers is poor,and it is easy to reduce the insulation of live equipment during operation.Therefore,it is particularly important to carry out operation and maintenance work on dry-type transformers.Based on this,research is conducted on the application of the combination tool of dry-type transformer cleaning and crack detection in the maintenance of subway traction power supply.Fully utilizing the limited"skylight"time to ensure the accuracy of maintenance and repair results not only improves maintenance and repair efficiency,but also shortens the power outage time of maintenance operations,reduces the workload of maintenance personnel,and ensures the safe and stable operation of the urban rail transit power supply system.
