Cov ntsuas ntse tau hloov pauv txoj kev saib xyuas thiab tswj kev siv hluav taws xob hauv tsev thiab chaw ua lag luam. Cov khoom siv siab heev no muab cov ntaub ntawv tiag tiag ntawm kev siv hluav taws xob, ua rau muaj kev them nqi raug dua, txhim kho kev siv hluav taws xob zoo dua, thiab tswj hwm lub network zoo dua. Hauv plawv ntawm cov ntsuas ntse no muaj ib qho tseem ceeb hu ua Manganin shunt, uas ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau tias qhov tseeb thiab kev ntseeg tau ntawm kev ntsuas hluav taws xob.
Manganin, ib qho hlau sib xyaw ua los ntawm tooj liab, manganese, thiab nickel, yog lub npe nrov rau nws qhov kub tsis kam, hluav taws xob tiv taus siab, thiab ruaj khov zoo heev ntawm ntau qhov kub thiab txias. Cov yam ntxwv no ua rau Manganin yog cov khoom siv zoo tshaj plaws rau kev siv hauv kev ntsuas hluav taws xob raug, suav nrog cov shunts siv hauv cov ntsuas ntse.
LubManganin shuntua haujlwm ua lub resistor ntsuas tam sim no hauv lub tshuab ntsuas ntse. Nws yog tsim los ntsuas qhov ntws ntawm cov hluav taws xob hla lub voj voog kom raug. Thaum hluav taws xob ntws los ntawm lub shunt, qhov poob hluav taws xob me me raug tsim tawm, uas yog proportional rau qhov tam sim no raug ntsuas. Qhov poob hluav taws xob no ces raug ntsuas kom raug thiab siv los xam qhov ntau ntawm lub zog siv. Qhov tseeb thiab kev ruaj khov ntawm Manganin shunt yog qhov tseem ceeb hauv kev ua kom ntseeg tau tias cov ntaub ntawv siv hluav taws xob los ntawm lub tshuab ntsuas ntse yog qhov ntseeg tau thiab ntseeg tau.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv Manganin shunts hauv cov ntsuas ntse yog lawv lub peev xwm los tswj kev ua haujlwm tas mus li. Cov hlau alloy qhov kub qis coefficient ntawm kev tiv thaiv txhais tau tias kev hloov pauv ntawm qhov kub thiab txias muaj qhov cuam tshuam tsawg kawg nkaus rau nws cov khoom hluav taws xob. Qhov no ua kom ntseeg tau tias qhov tseeb ntawm shunt tseem tsis cuam tshuam los ntawm kev hloov pauv ntawm cov xwm txheej ib puag ncig, ua rau nws zoo rau kev siv mus sij hawm ntev hauv cov ntawv thov ntsuas ntse.
Tsis tas li ntawd xwb, Manganin shunts muab kev ntsuas qhov tseeb thiab tsis muaj kev tsis paub meej, uas ua rau cov ntsuas ntse muab cov ntaub ntawv siv hluav taws xob raug thiab ntseeg tau. Qhov no tseem ceeb heev rau cov tuam txhab hluav taws xob thiab cov neeg siv khoom, vim nws ua rau kev them nqi ncaj ncees thiab pob tshab raws li kev siv hluav taws xob tiag tiag. Tsis tas li ntawd xwb, qhov ruaj khov ntawm Manganin shunts pab txhawb rau kev ntseeg tau tag nrho ntawm cov txheej txheem ntsuas ntse, ua kom ntseeg tau tias lawv txuas ntxiv xa cov kev ntsuas raug thoob plaws lawv lub neej ua haujlwm.
Ntxiv rau lawv cov khoom siv hluav taws xob, Manganin shunts kuj tseem muaj nqis rau lawv qhov kev ua haujlwm ruaj khov thiab tiv taus xeb. Cov cwj pwm no ua rau lawv zoo rau kev xa mus rau ntau yam xwm txheej ib puag ncig, suav nrog kev teeb tsa sab nraum zoov qhov twg raug dej noo, plua plav, thiab qhov kub thiab txias sib txawv. Qhov ruaj khov ntawm Manganin shunts pab txhawb rau lub neej ntev thiab kev ntseeg siab ntawm cov ntsuas ntse, tso cai rau lawv ua haujlwm tau zoo hauv cov chaw ua haujlwm nyuaj.
Raws li qhov kev thov rau cov kev daws teeb meem ntse metering txuas ntxiv mus, lub luag haujlwm ntawmCov tshuaj manganin shuntsHauv kev ua kom muaj kev ntsuas lub zog raug thiab txhim khu kev qha tsis tuaj yeem hais ntau dhau. Lawv cov khoom siv hluav taws xob thiab cov khoom siv kho tshuab zoo heev ua rau lawv yog ib qho tseem ceeb hauv kev tsim cov txheej txheem ntsuas ntse siab heev. Los ntawm kev siv qhov tseeb thiab kev ruaj khov ntawm Manganin shunts, cov chaw muab kev pabcuam thiab cov neeg siv khoom tuaj yeem tau txais txiaj ntsig los ntawm kev tswj hwm lub zog kom pom tseeb thiab ua haujlwm tau zoo dua, thaum kawg pab txhawb rau kev tsim kho lub zog kom ruaj khov thiab muaj zog dua.
Xaus lus, kev siv Manganin shunts hauv cov ntsuas ntse yog ib qho kev nce qib tseem ceeb hauv kev ntsuas thiab tswj lub zog. Lawv lub peev xwm los muab qhov tseeb, ruaj khov, thiab txhim khu kev qha kev ntsuas tam sim no yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov txheej txheem ntsuas ntse. Thaum kev lag luam hluav taws xob txuas ntxiv txais yuav cov thev naus laus zis ntse, Manganin shunts yuav tseem yog lub hauv paus tseem ceeb hauv kev ua kom muaj kev ncaj ncees thiab qhov tseeb ntawm cov ntaub ntawv siv hluav taws xob, thaum kawg tsav tsheb ua haujlwm tau zoo dua thiab ruaj khov hauv kev tswj hwm lub zog hluav taws xob.
