1) miss trip
误跳闸
1.
Because two sets of trip loop of 330kV breaker were not completely seperated in a substation,when a negative power source disappears in two groups operation power supply,caused the mannual trip relay miss action and made the breaker three -phase miss trip.
某变电站由于330kV断路器2套跳闸回路未完全隔离,造成2组操作电源中的一负电源消失时,手跳继电器误动作,使断路器三相误跳闸。
2) maloperation
错误跳闸
3) nuisance trip
误跳车
1.
Unlike sensor subsystem whose nuisance trip can be detected and bypassed by logical solver,the spurious failure of final element may leads directly to the nuisance trip of overall system.
需用故障率(PFD)及误跳车(MTTFS)是联锁系统定量安全评定中两个重要指标。
4) generator maloperation
机组误跳
