摘　　要：简述了需要进行母线保护搭接验证的技改工程类型,探讨了将母线保护校验与母线保护搭接工作相配合,更好地验证跳闸回路完整性的新思路。该母线保护跳闸回路验证方式避免了在母线保护搭接现场频繁拆接运行间隔跳闸回路端子,有效降低了母线保护误跳运行间隔风险,助力电网安全稳定运行。This paper briefly describes the types of technical retrofit in which wiring and verification of busbar protection are mandatory procedures,discusses the new idea of realizing the coordination of wiring and verification of busbar protection to facilitate integrity checking of the tripping circuit.The proposed method avoids frequent disconnection of the charged tripping circuit terminals in the step of busbar protection wiring,effectively reduces the risk of undesired trip of busbar protection,and helps ensure safe and stable operation of power grids.
