Tam sim no Sensing Element-Sense resistor

Tam sim no Sensing Element-Sense resistor:

Tam sim no hnov tau hais txog lub cim ntawm qhov teeb meem ntawm qhov hluav taws xob uas muaj feem xyuam rau qhov tam sim no dhau los hauv Circuit Court. Ib qho kev coj ntawm kev paub txog qhov tam sim no yog los ntxig rau tus neeg uas tawv nqaij nyob ntawm txoj hauv kev tam sim no. Tom qab ntawd peb tuaj yeem tso qhov hnov qab tias nws nyob rau hauv txhua qhov chaw nrog lub voj voog uas nws muaj peev xwm pib los yog hloov. Yog li tam sim no cov cuab tam sensing yuav tsum tau muab xam raws li tam sim no rau voltage converter.

Yam yuav tshwm sim ntawm qhov kev ua haujlwm ntawm qhov kev xav ntawm lub cev

· Cov nqi yuav tsum tau qis qis kom txo qis qis zog:

Qhov tseem ceeb tshaj tam sim no feem ntau yog nyob ntawm qhov pib qhov hluav taws xob ntawm qhov Circuit Court uas nws lub lag luam yog ua tiav raws li cov ntaub ntawv tam sim no.

· Los nce qhov tseeb uas peb yuav tsum xav txog kev ntsuas qis dua:

Kub yog qhov tseem ceeb ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm qhov tseeb. Resistor nrog cov kub coefficient ua kom ze rau xoom, hauv tag nrho cov lag luam uas yuav tsum tau siv. Hwj chim tawm ntawm lub cav muaj zog tuaj yeem pub tau hluav taws xob txawv ntawm qhov sib txawv. Tab sis muaj peev xwm hwj chim ntau zog yog qhov ua kom muaj zog; li no lub zog ntaus nqi yuav tsum tau muab rau hauv koj tus account

Pros thiab Cons ntawm tam sim no hnov mob resistors muaj xws li

Tshaj:

· Cov nqi qis heev thaum piv rau lwm cov khoom siv.

· Kev siab tsis ncaj tshaj plaws

· Computable tam sim no los ntawm cov uas tsis tshua muaj siab mus rau theem nrab

· Kev muaj peev xwm txiav txim siab DC los yog AC tam sim no

Txais:

· Tawm tswv yim txhawb ntxiv rau txoj kev ntsuas kev ntsuas, uas tej zaum yuav ua rau kom cov zis tawm ntawm cov khoom tso tawm thiab qhov tshwm sim hauv kev ua haujlwm tsis zoo.

· Fais fab tuag poob vim qhov kev coj ua fais fab tuag. Txawm li cas los, tam sim no hnov tau cov resistors tsis tshua siv tawm ntawm qhov qis thiab nruab nrab tam sim no sensing daim ntawv sau npe.

Ob txoj kev ntawm kev ntxim nyiam tam sim no:

1. Ncaj nraim tam sim no:

Kev ncaj qha tam sim no yog nyob ntawm Ohm txoj cai. Thaum muab qhov sib dhos tsis sib haum hauv kev kho nrog qhov system load, ib qho hluav taws xob yog tshwm sim thoob plaws lub pob tw ntawm lub cev uas muaj feem cuam tshuam rau qhov kev thauj khoom tam sim no. Lub siab dhau lub shunt yuav raug ntsuas los ntawm kev sib txawv amplifiers piv txwv tam sim no shunt amplifiers, ua hauj lwm amplifiers los yog txawv amplifiers. Nws yog feem ntau siv rau load currents <>

2. Tam sim no tsis hnov lus:

Kev tsis ncaj ncees tam sim no yog nyob ntawm Ampere thiab Faraday cov cai. Thaum muab lub voj nyob ib ncig ntawm tus neeg xyuas pib nqa tam sim no, ib qho hluav taws xob yog vim raug yuam dhau lub voj uas yog proportional rau qhov tam sim no. Cov hom kev kho no siv rau 100A - 1000A load currents.

Low-Side Tam sim no Sensing:

Nws yog tus tswv yim qis hom qis tshaj. Tsawg-tam sim no tsom mus rau qhov hnov qhov hnov qab ntawm qhov load thiab hauv av. Qhov no yog ntshaw vim hais tias hom common-voltage yog nyob ze rau hauv av, uas yog siv los ntawm kev siv cov kev siv ib zaug, kev tsheb nqaj hlau los ntawm kev tawm tswv yim / tso zis op-amps. Thauj khoom yog muab rau tib cov khoom thiab cov ua haujlwm yog grounded. Cov teeb meem rau kev sib tw tsis tshua muaj qhov cuam tshuam rau qhov kev thauj khoom hauv av muaj peev xwm thiab qhov tsis muaj peev xwm txhom tau cov tsheb luv luv.

Siab Sab Tam Sim No Tam Sim No:

High-sab tam sim no hnov txog qhov hnov qhov hnov qab ntawm lub hwj huam thiab kev thauj.

High-sensing yog ntshaw vim nws ncaj qha tsom kwm tam sim no tauj los ntawm kev txaus siab, uas txiav txim siab txog kev txheeb xyuas cov tsheb luv. Qhov kev ntsuam xyuas yog tias qhov kev hloov lub zog ntawm tus qauv ntau hom dav hlau yuav tsum muaj raws li tus qauv qhov khoom thauj cov khoom hluav taws xob. Thaum kawg tawm yog ntsuas thoob plaws lub cuab tam sensed tam sim no, thiab load yog grounded. Daim duab hauv qab no yog sawv cev rau thawj theem nrab thiab theem ob sab tam sim no:

Tam sim no Transformer (CT):

Tam sim no transformer (CT) yog ib qho siv hluav taws xob siv los ntsuas cov dej hluav taws xob. Kuv yog cov lees paub dav tshaj plaws nyob thoob plaws hnub no lub siab zog tam zog ntawm lub xeev-lub zog. Nws tuaj yeem ntsuas siab txog kev kub ntxhov thiab kev siv zog tsawg zog. Nws tseem yog ib qho tseem ceeb heev hauv kev ntsuas los yog saib xyuas tam sim no siab, high voltage thiab high power circuits. Cov no yog siv rau hauv lub zog ntawm txhua yam, xws li cov khoom siv hluav taws xob, kev tswj lub cev, kev tswj teeb pom kev zoo.

Tam sim no Transformer:

Cov kev ntsuas no muab cov ntaub ntawv tseem ceeb rau kev tswj thiab kev nyab xeeb. Thiab tsim ib qho teeb liab tso tawm raws qhov ntsuas tam sim no.

Nta ntawm Cov Tam Sim No:

· Ntsuas AC nkaus xwb

· Hluav Taws Xob Hluav Taws Xob

· Tsis muaj zog txaus

· Tus nqi qis dua

Cov kev ntsuas no hnub no yog siv dav hauv txhua lub lag luam vim hais tias ntawm lawv cov kev siv loj thiab hom ntawm cov zis lawv muab uas tswj tau thiab siv tau rau cov ntawv thov sib txawv.

Tam sim no Hnov qhov voltage txo proportional rau cov thauj tam sim no hla lub resistor ntawm 10R yog noj thiab yog stepped los ntawm ib tus transformer ( CT) los pub rau tus choj rectifier los ua pulsating dc rau lub comparator los tsim tam sim no. Tus comparator generates cov xoom hla pulses ntawm pulsating DC

Cov kev siv ntawm cov sensor tam sim no:

· Qhib voj tam sim no siv sensor siv TLE4998S.

· Tam sim no sensor siv TLE4998S nyob rau hauv ntau xaiv hom.www.ctsensorducer.com
