浅淡牵引变电所备自投装置检测方式改进

Discussion of Improvement of Inspection Mode for Automatic Switching of Standby Equipment in Traction Substation

分析了牵引变电所备自投保护功能检测方式的不足,介绍了一种在高压设备不停电情况下校验备自投保护功能的检测方法,说明了其工作原理、主要功能等。该备自投离线校验装置的使用弥补了在牵引变电所备自投保护检测方面的不足,进一步提高了牵引供电系统的供电可靠性。

The paper analyzes the disadvantages of inspection mode for automatic switching of standby equipment in traction substation,introduces an inspection method for automatic switching of standby equipment under a condition that the high voltage equipment is energized,illustrates its working principles and main functions.The application of off-line inspection device for the automatic switching of standby equipment compensates for the disadvantages of protection and inspection of automatic switching of standby equipment in traction substation,further improve the power supply reliability of traction power supply system.
