Nyob rau hauv lub realm ntawm hluav taws xob engineering thiab kev ntsuas, precision yog qhov tseem ceeb. Ib qho ntawm cov tseem ceeb ntawm cov khoom tseem ceeb uas tau yooj yim ntsuas tam sim no yog lub shunt resistor. Ntawm cov ntaub ntawv ntau yam siv rau shunts, manganin sawv tawm vim nws cov khoom tshwj xeeb. Tsab ntawv no rho tawm rau dab tsiMannanin shuntsyog, cov ntaub ntawv siv rau shunts, thiab lawv cov ntawv thov tshwj xeeb.
Dab tsi yog shunt?
Ib lub shunt yog cov khoom tiv thaiv tsawg uas tau muab tso rau hauv parallel nrog cov cuab yeej ntsuas, xws li ammeter, kom tso cai rau kev ntsuas ntawm cov twj siab uas tsis muaj kev ua kom lub ntsuas kub. Los ntawm kev siv Ohm txoj cai, tus voltage poob hla lub shunt tuaj yeem ntsuas, uas yog tom qab ntawd tau siv los laij cov ntws tam sim no los ntawm Circuit Court.
Cov khoom siv yog siv rau shunt?
Shunt resors tuaj yeem ua los ntawm ntau cov ntaub ntawv, txhua qhov kev sib txawv ntawm qhov zoo thiab qhov tsis zoo. Cov Khoom Siv Uas Muaj:
Tooj liab: paub txog nws txoj kev ua haujlwm zoo, tooj liab feem ntau siv hauv cov ntawv thov tsawg. Txawm li cas los xij, nws qhov ntxim nyiam ua rau oxidation tuaj yeem ua rau tsis muaj tseeb lub sijhawm.
Nickel: Nickel Shunts yog ruaj thiab tiv taus corrosion, ua rau lawv haum rau cov chaw hnyav. Txawm li cas los xij, lawv tsis yog tus cwj pwm zoo li tooj liab.
MANAGIN: Qhov no yog ib qho tagnrho muaj nyob hauv tooj liab, manganese, thiab npib tsib xee. MANAGIN muaj kev nyiam rau cov ntawv thov shunt vim nws qhov kub kub ua kom tsis kam, uas txhais tau tias nws txoj kev tawm tsam zoo me ntsis nrog kev kub hloov. Qhov kev ruaj khov no yog qhov tseem ceeb rau kev ntsuas yog qhov tseeb.
Constantan: lwm qhov alloy, feem ntau ntawm tooj liab thiab npib tsib xee, constantan feem ntau siv hauv thermocouples thiab shunts vim nws ruaj khov thiab tsis kam thiab oxidation.
Dab tsi yog manganin shunt siv rau?
Mannanin shuntstau siv dav hauv ntau daim ntawv thov vim lawv cov khoom ntiag tug. Nov yog qee qhov ntawm thawj siv:
Precision Kev Ntsuas Tam Sim No: MANAGININS feem ntau yog ua haujlwm hauv Ammeters thiab lwm cov cuab yeej ntsuas uas yuav tsum muaj qhov tseeb. Lawv cov coefficiecious tsawg uas cov kev tawm tsam tseem ruaj khov, muab kev txhim kho txhim khu kev qha.
Cov Qauv Calibration: Hauv lub chaw sojntsuam cov qauv: Hauv chaw saib xyuas, manicin shunts feem ntau siv los ua cov qauv ntsuas hluav taws xob rau cov twj ntsuas lwm yam ntsuas. Lawv txoj kev coj cwj pwm tau raws kev sib txawv ua rau lawv zoo tshaj rau lub hom phiaj no.
Lub zog ntsuas: Hauv lub zog hluav taws xob, cov tawv nqaij manicnin tau siv los ntsuas cov dej khov loj uas tsis tau qhia cov khoom tseem ceeb. Qhov no yog qhov tseem ceeb rau kev tswj cov kev ua haujlwm thiab kev nyab xeeb.
Cov Kev Siv Cov Khoom Siv: MANAGININS tau siv nyob rau hauv ntau cov ntawv thov, suav nrog kev ntsuas lub cev muaj zog, qhov chaw ntsuas hluav taws xob muaj tseeb yog qhov tseem ceeb rau kev ua haujlwm.
Kev tshawb fawb thiab kev txhim kho: hauv R & D chaw, manicin shunts tau siv hauv kev sim teeb tsa uas tsim nyog rau cov ntaub ntawv sau thiab tshuaj xyuas.

Mannanin shuntssawv cev rau qhov tseem ceeb nyob hauv thaj teb ntsuas hluav taws xob. Lawv cov khoom siv tshwj xeeb, tshwj xeeb yog lawv cov ntsuas kub tsawg dua, ua rau lawv zoo tshaj plaws rau cov ntawv thov thiab kev ruaj khov. Txawm hais tias nyob rau hauv cov chaw muaj kev lag luam, chaw soj nstuam, manicin shunts ua si lub luag haujlwm tseem ceeb hauv kev ntsuas hluav taws xob uas muaj kev ntseeg siab thiab meej. Raws li thev naus laus zis txuas ntxiv mus ua ntej, qhov tseem ceeb ntawm kev ntsuas tam sim no tsuas yog cog qoob loo, solidifying lub luag haujlwm ntawm manganin shunts hauv kev tsim hluav taws xob mandganin.
