在电力系统中，变电站的一些配套保护设备是保证电网稳定运行的至关重要的一部分。传统意义上的继电保护是指为了保证电网的回路接线及定值准确、元件装置完好和功能正常而采用的设备及对电网的定期检查。目前的检查项目主要包括电网的安全自动装置，继电保护和二次回路接线。这是设备检修体制从计划检修向状态检修转化的一个重要转折，使设备检修体制变得更加科学、规范。因此，在一次设备状态检修技术的基础上对二次设备系统特别是继电保护系统进行研究很有必要。文章分析了变电站检修继电保护设备的常见问题，并给出了处理措施。

In power systems,supporting protection of substation equipment is part of the crucial importance of ensu-ring stable operation of power system.Traditional relay protection refers to regular inspections to ensure loop wiring and setting the grid accurate,intact and functioning element device taken on the grid.The present inspection project mainly in-cludes the grid security automatic equipment,relay protection and the secondary circuit wiring.This is an important turn-ing point in the equipment maintenance system from scheduled maintenance to condition-based maintenance transformation;make equipment maintenance system become more scientific and standardized.Therefore,the secondary device system based on the equipment state maintenance,especially the study of relay protection system is necessary.
