跳閘，解扣，松開(彈簧)trip

翻譯繼電器是保護(hù)系統(tǒng)的邏輯元件，它感知故障，并使斷路器解扣電路帶電和斷路器打開觸點(diǎn)。BasicConceptsofElectricPowerSystem說明由which引導(dǎo)的定語從句修飾的主體為thelogicelements而不是aprotectionsystem。定語從句有兩個(gè)并列的謂語動(dòng)詞sense和cause，第一個(gè)and就是連接這兩個(gè)動(dòng)詞短語的。而cause又帶有兩個(gè)并列的賓補(bǔ)結(jié)構(gòu)，中間也是用and連接。BasicConceptsofElectricPowerSystem2.Arelayusedforprotectionshouldmakeitsdecisionasquicklyaspossible,consistentwithotherrequirementsplaceduponit.嘗試翻譯2.Arelayusedforprotectionshouldmakeitsdecisionasquicklyaspossible,consistentwithotherrequirementsplaceduponit.生詞adj.一致的；與…一致的consistent

翻譯在與其它外加要求相容的條件下，用于保護(hù)的繼電器應(yīng)該盡可能快的做出決定。朱永強(qiáng)zyq@BasicConceptsofElectricPowerSystem說明詞組asquicklyaspossible表示“盡可能的快”。consistentwithotherrequirementsplaceduponit是條件狀語從句省略為短語，可補(bǔ)全為：undertheconditionthatitisconsistentwithotherrequirementsplaceduponit.BasicConceptsofElectricPowerSystem3.Therelayshouldoperateconsistentlyforallthefaultsforwhichitisdesignedtooperate,andshouldrefrainfromoperatingforanyothersystemcondition.嘗試翻譯3.Therelayshouldoperateconsistentlyforallthefaultsforwhichitisdesignedtooperate,andshouldrefrainfromoperatingforanyothersystemcondition.生詞v.避免；克制refrain翻譯繼電器應(yīng)該始終在按其設(shè)計(jì)應(yīng)該動(dòng)作的所有故障下動(dòng)作，并且對于任何其它的系統(tǒng)條件避免動(dòng)作。BasicConceptsofElectricPowerSystem說明定語從句forwhichitisdesignedtooperate修飾的主體是faults，其句式和含義與that引導(dǎo)的賓語從句基本相同，只是在作定語從句時(shí)，將operate后面的for提到了引導(dǎo)詞which之前。為了便于理解，這個(gè)句子可以拆解為：Reliabilitymeansthattherelayshouldoperateconsistentlyforallthosefaults;therelayisdesignedtooperateforthosefaults;therelayshouldrefrainfromoperatingforanyothersystemcondition.BasicConceptsofElectricPowerSystem4.Back-upprotectionasthenameimpliesisacompletelyseparatearrangementwhichoperatestoremovethefaultypartshouldbemainprotectionfailtooperate.嘗試翻譯4.Back-upprotectionasthenameimpliesisacompletelyseparatearrangementwhichoperatestoremovethefaultypartshouldbemainprotectionfailtooperate.生詞v.意味著；暗示imply翻譯顧名思義，后備保護(hù)是完全的獨(dú)立安排，一旦主保護(hù)未能動(dòng)作時(shí)由它動(dòng)作去切除故障部分。BasicConceptsofElectricPowerSystem說明shouldbe部分是虛擬語氣的用法，表示假設(shè)的情況。詞組asthenameimplies表示“正如名字所暗示的，顧名思義”。BasicConceptsofElectricPowerSystem5.Thejobofeachofthesesubsystemscanbestbeunderstoodbydescribingtheeventsthattakeplacefromthetimeofoccurrenceofafaulttoitseventualeliminationfromthepowersystem.嘗試翻譯5.Thejobofeachofthesesubsystemscanbestbeunderstoodbydescribingtheeventsthattakeplacefromthetimeofoccurrenceofafaulttoitseventualeliminationfromthepowersystem.生詞n.消除；消滅elimination翻譯每一個(gè)子系統(tǒng)的任務(wù)，可以通過故障發(fā)生時(shí)刻到它最終被從電力系統(tǒng)中清除期間所發(fā)生的事件來最好地理解。BasicConceptsofElectricPowerSystem說明句中出現(xiàn)了四個(gè)of和兩個(gè)from，這樣多的介詞連續(xù)出現(xiàn)，在翻譯時(shí)要格外注意句子的通順。在that引導(dǎo)的定語從句中，fromthetime…to…作為takeplace的狀語，說明“發(fā)生”的時(shí)間范圍。BasicConceptsofElectricPowerSystem6.Troublemayariseduetothemagnetizingcurrentinrushonswitchingoperatingtherelay,andoftenrestrainingcoilssensitivetothirdharmoniccomponentsofthecurrentareincorporatedintherelays.嘗試翻譯6.Troublemayariseduetothemagnetizingcurrentinrushonswitchingoperatingtherelay,andoftenrestrainingcoilssensitivetothirdharmoniccomponentsofthecurrentareincorporatedintherelays.生詞n.

泛音；和聲harmonic

adj.

和聲的翻譯由于勵(lì)磁電流涌入，在操作繼電器的開關(guān)問題上會(huì)出現(xiàn)麻煩，往往把對電流的三次諧波分量敏感的遏制線圈集成到繼電器中。BasicConceptsofElectricPowerSystem說明dueto引導(dǎo)的狀語短語，在翻譯時(shí)應(yīng)提前。onswitching是trouble的定語，而switching本身帶有一個(gè)分詞短語形式的定語operatingtherelay。sensitivetothirdharmoniccomponentsofthecurrent是restrainingcoils的定語。為了便于理解，這個(gè)句子可以拆解為：Duetothemagnetizinginrushcurrent,troublemayarise;troubleisonswitch
