摘　　要：对某110kV变电站35kV母线专用保护闭锁自切的动作过程进行了详细分析,并通过现场试验查证了母线专用保护闭锁自切的动作逻辑,找出了保护逻辑所存在的问题,并提出了相应的改进措施,旨在能够完善母线专用保护与自切之间的配合,具有一定的现实意义。The paper expounds the self-cutting process of 35 kV special bus protection blocking in one ll0KV substation. In the on-site testing, the action logic was verified; the protection logic problems were identified. In order to improve the coordination of special bus protection and self-cutting protection, the corresponding practical improvement measures were put forward.
