摘　　要：某变电站110kV线路保护更换后采用保护操作箱的防跳回路,通过检查发现,在操作箱跳合闸电流没整定情况下,开关能够正常分合,但是影响了防跳回路的正常功能,以国电南自PSL621U保护装置为例,分析跳合闸电流的整定对控制回路及防跳回路的影响。A substation 110kV line protection after replacement used operation box trip prevention circuit protection, by checking the results, under the situation of no setting in operation box tripping and switc- hing current, the switch works properly, but the normal function of the trip prevention circuit is affected. Taking PSL621U protection device as an example, this paper analyzes the effect of the setting of the trip- ping and switching current on the control circuit and the trip prevention circuit.
