| Abstract: | 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 PSL621 U 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 . |
