摘　　要：本文针对目前电网常规电磁型保护出口中间继电器BCJ的动作电压线圈经常易断,导致继电保护可靠性降低的情况,对其原因进行了系统分析,提出了出口中间继电器BCJ出口回路改进办法。In this paper, aiming at the case that the reliability of conventional electromagnetic protection in power network present is reduced caused from the voltage coils of exit intermediate relay BCJ are easy to be broken during its operation, and analyzing the reason, the author presents the measures for improving the exit-circuit of exit intermediate relay BCJ.

关 键 词：电磁型保护 出口回路 改进
