Nyob rau hauv lub realm ntawm hluav taws xob engineering thiab ntsuas, precision yog qhov tseem ceeb. Ib qho ntawm cov khoom tseem ceeb uas pab txhawb qhov ntsuas tam sim no yog shunt resistor. Ntawm ntau yam khoom siv rau shunts, Manganin sawv tawm vim nws cov khoom tshwj xeeb. Kab lus no delves rau hauv dab tsiManganin swbyog, cov ntaub ntawv siv rau shunts, thiab lawv cov kev siv tshwj xeeb.
Shunt yog dab tsi?
Lub shunt yog ib qho kev tiv thaiv qis uas tau muab tso rau hauv qhov sib npaug nrog lub ntsuas ntsuas, xws li ammeter, tso cai rau kev ntsuas cov dej ntws siab yam tsis muaj kev puas tsuaj rau lub ntsuas. Los ntawm kev siv Ohm txoj cai, qhov hluav taws xob poob thoob plaws lub shunt tuaj yeem ntsuas tau, uas yog siv los ntsuas qhov tam sim no ntws los ntawm lub voj voog.
Dab tsi yog cov khoom siv rau Shunt?
Shunt resistors tuaj yeem tsim los ntawm ntau yam ntaub ntawv, txhua qhov muab qhov zoo thiab qhov tsis zoo. Cov ntaub ntawv uas muaj xws li:
Copper: Paub txog nws cov conductivity zoo heev, tooj liab feem ntau siv rau hauv cov ntawv siv qis tam sim no. Txawm li cas los xij, nws qhov cuam tshuam rau oxidation tuaj yeem ua rau tsis raug raws sijhawm.
Nickel: Nickel shunts yog qhov ruaj thiab tiv taus corrosion, ua rau lawv haum rau qhov chaw hnyav. Txawm li cas los xij, lawv tsis yog conductive li tooj liab.
Manganin: Qhov no yog ib qho alloy uas feem ntau yog tooj liab, manganese, thiab npib tsib xee. Manganin yog tshwj xeeb tshaj yog nyiam rau shunt daim ntaub ntawv vim nws tsis tshua muaj kub coefficient ntawm tsis kam, uas txhais tau hais tias nws tsis kam hloov me ntsis nrog kub hloov. Qhov kev ruaj ntseg no tseem ceeb heev rau kev ntsuas kom raug.
Constantan: Lwm alloy, feem ntau ntawm tooj liab thiab npib tsib xee, Constantan feem ntau yog siv rau hauv thermocouples thiab shunts vim nws zoo stability thiab tsis kam mus oxidation.
Manganin Shunt siv rau dab tsi?
Manganin swbtau siv dav hauv ntau daim ntawv thov vim lawv cov khoom tshwj xeeb. Nov yog qee qhov kev siv tseem ceeb:
Kev ntsuas tam sim no Precision: Manganin shunts feem ntau ua haujlwm hauv ammeters thiab lwm yam khoom siv ntsuas qhov yuav tsum tau muaj qhov tseeb. Lawv qhov kub tsis tshua muaj coefficient ua kom ntseeg tau tias qhov kev tiv thaiv tseem nyob ruaj khov, muab kev nyeem ntawv zoo.
Calibration Standards: Nyob rau hauv lub chaw soj nstuam, Manganin shunts feem ntau yog siv raws li calibration qauv rau lwm yam ntsuas. Lawv tus cwj pwm uas xav tau nyob rau hauv ntau yam xwm txheej ua rau lawv zoo tagnrho rau lub hom phiaj no.
Kev ntsuas hluav taws xob: Hauv cov tshuab hluav taws xob, Manganin shunts yog siv los ntsuas cov tam sim no loj yam tsis muaj kev qhia txog qhov hluav taws xob tseem ceeb. Qhov no yog qhov tseem ceeb rau kev tswj xyuas qhov system efficiency thiab kev nyab xeeb.
Cov ntawv thov kev lag luam: Manganin shunts yog siv rau hauv ntau daim ntawv thov kev lag luam, suav nrog kev tswj lub cev muaj zog thiab lub zog faib hluav taws xob, qhov ntsuas qhov tseeb tam sim no tseem ceeb rau kev ua haujlwm zoo.
Kev Tshawb Fawb thiab Kev Txhim Kho: Hauv R & D chaw, Manganin shunts yog siv rau hauv kev sim teeb tsa qhov kev ntsuas tam sim no yog qhov tsim nyog rau kev sau thiab tshuaj xyuas cov ntaub ntawv.

Manganin swbsawv cev rau qhov tseem ceeb hauv kev ntsuas hluav taws xob. Lawv cov khoom siv tshwj xeeb, tshwj xeeb tshaj yog lawv cov coefficient kub ntawm qhov tsis kam, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau qhov tseeb thiab ruaj khov. Txawm hais tias nyob rau hauv cov chaw tsim khoom, chaw kuaj mob, lossis lub tshuab hluav taws xob, Manganin shunts ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau tias kev ntsuas hluav taws xob yog ob qho tib si txhim khu kev qha thiab meej. Raws li thev naus laus zis txuas ntxiv mus, qhov tseem ceeb ntawm kev ntsuas tam sim no tsuas yog loj hlob, ua kom lub luag haujlwm ntawm Manganin shunts hauv kev tsim hluav taws xob niaj hnub no.
