摘要
操作机构与保护装置均设有电气防跳回路,因此在断路器控制回路接线过程中,经常存在操作机构与保护装置接口的问题,通过对110 kV断路器弹簧操作机构与110 kV微机保护装置两种防跳回路的分析,说明了如果同时采用两种防跳回路存在的问题,并给出了确定防跳回路是否完整的试验方法。
Both the operative mechanism and protections have the leap-preventive circuits, so it is necessary to pay attention to the secondary circuit connection of the operative mechanic and protections.According to the analysis of the leap-preventive circuits of the 110 kV SF6 CB spring operative and protection,the problem when those two circuits work at the same time is explained, and the methods of test in the leap-preventive circuit are presented.
