跳闸，解扣，松开(弹簧)trip

翻译继电器是保护系统的逻辑元件，它感知故障，并使断路器解扣电路带电和断路器打开触点。BasicConceptsofElectricPowerSystem说明由which引导的定语从句修饰的主体为thelogicelements而不是aprotectionsystem。定语从句有两个并列的谓语动词sense和cause，第一个and就是连接这两个动词短语的。而cause又带有两个并列的宾补结构，中间也是用and连接。BasicConceptsofElectricPowerSystem2.Arelayusedforprotectionshouldmakeitsdecisionasquicklyaspossible,consistentwithotherrequirementsplaceduponit.尝试翻译2.Arelayusedforprotectionshouldmakeitsdecisionasquicklyaspossible,consistentwithotherrequirementsplaceduponit.生词adj.一致的；与…一致的consistent

翻译在与其它外加要求相容的条件下，用于保护的继电器应该尽可能快的做出决定。朱永强zyq@BasicConceptsofElectricPowerSystem说明词组asquicklyaspossible表示“尽可能的快”。consistentwithotherrequirementsplaceduponit是条件状语从句省略为短语，可补全为：undertheconditionthatitisconsistentwithotherrequirementsplaceduponit.BasicConceptsofElectricPowerSystem3.Therelayshouldoperateconsistentlyforallthefaultsforwhichitisdesignedtooperate,andshouldrefrainfromoperatingforanyothersystemcondition.尝试翻译3.Therelayshouldoperateconsistentlyforallthefaultsforwhichitisdesignedtooperate,andshouldrefrainfromoperatingforanyothersystemcondition.生词v.避免；克制refrain翻译继电器应该始终在按其设计应该动作的所有故障下动作，并且对于任何其它的系统条件避免动作。BasicConceptsofElectricPowerSystem说明定语从句forwhichitisdesignedtooperate修饰的主体是faults，其句式和含义与that引导的宾语从句基本相同，只是在作定语从句时，将operate后面的for提到了引导词which之前。为了便于理解，这个句子可以拆解为：Reliabilitymeansthattherelayshouldoperateconsistentlyforallthosefaults;therelayisdesignedtooperateforthosefaults;therelayshouldrefrainfromoperatingforanyothersystemcondition.BasicConceptsofElectricPowerSystem4.Back-upprotectionasthenameimpliesisacompletelyseparatearrangementwhichoperatestoremovethefaultypartshouldbemainprotectionfailtooperate.尝试翻译4.Back-upprotectionasthenameimpliesisacompletelyseparatearrangementwhichoperatestoremovethefaultypartshouldbemainprotectionfailtooperate.生词v.意味着；暗示imply翻译顾名思义，后备保护是完全的独立安排，一旦主保护未能动作时由它动作去切除故障部分。BasicConceptsofElectricPowerSystem说明shouldbe部分是虚拟语气的用法，表示假设的情况。词组asthenameimplies表示“正如名字所暗示的，顾名思义”。BasicConceptsofElectricPowerSystem5.Thejobofeachofthesesubsystemscanbestbeunderstoodbydescribingtheeventsthattakeplacefromthetimeofoccurrenceofafaulttoitseventualeliminationfromthepowersystem.尝试翻译5.Thejobofeachofthesesubsystemscanbestbeunderstoodbydescribingtheeventsthattakeplacefromthetimeofoccurrenceofafaulttoitseventualeliminationfromthepowersystem.生词n.消除；消灭elimination翻译每一个子系统的任务，可以通过故障发生时刻到它最终被从电力系统中清除期间所发生的事件来最好地理解。BasicConceptsofElectricPowerSystem说明句中出现了四个of和两个from，这样多的介词连续出现，在翻译时要格外注意句子的通顺。在that引导的定语从句中，fromthetime…to…作为takeplace的状语，说明“发生”的时间范围。BasicConceptsofElectricPowerSystem6.Troublemayariseduetothemagnetizingcurrentinrushonswitchingoperatingtherelay,andoftenrestrainingcoilssensitivetothirdharmoniccomponentsofthecurrentareincorporatedintherelays.尝试翻译6.Troublemayariseduetothemagnetizingcurrentinrushonswitchingoperatingtherelay,andoftenrestrainingcoilssensitivetothirdharmoniccomponentsofthecurrentareincorporatedintherelays.生词n.

泛音；和声harmonic

adj.

和声的翻译由于励磁电流涌入，在操作继电器的开关问题上会出现麻烦，往往把对电流的三次谐波分量敏感的遏制线圈集成到继电器中。BasicConceptsofElectricPowerSystem说明dueto引导的状语短语，在翻译时应提前。onswitching是trouble的定语，而switching本身带有一个分词短语形式的定语operatingtherelay。sensitivetothirdharmoniccomponentsofthecurrent是restrainingcoils的定语。为了便于理解，这个句子可以拆解为：Duetothemagnetizinginrushcurrent,troublemayarise;troubleisonswitch
