Nyob rau hauv ib qho ntawm peb cov haujlwm thaum ntxov nrog cov neeg siv khoom lag luam automation hauv Qaib Cov Txwv, tus kws tshaj lij tau xa peb cov lus nug yooj yim uas tau muab los nthuav qhia qhov kev nkag siab tob tob:
"Peb tab tom siv pulse transformers thiab tam sim no transformers nyob rau hauv tib lub txee tswj. Lawv zoo sib xws. Lawv puas tau interchangeable?"
Qhov no yog ib lo lus nug ntau heev nyob rau hauv tiag tiag engineering ib puag ncig. Thaum xub thawj siab ib muag, ob qho tib si yog cov khoom siv sib nqus me me nrog windings ntawm lub hauv paus. Ob leeg muab kev cais tawm. Ob leeg yog siv rau hauv cov tshuab hluav taws xob uas muaj kev hloov pauv lossis ntsuas. Tab sis nyob rau hauv kev xyaum, lawv yog tsim rau lub cev sib txawv kiag li.
Ntawm Wuxi Huipu Electronics Co., Ltd., peb feem ntau piav qhia qhov txawv ntawm qhov yooj yim tshaj plaws: ib qho yog tsim los xa cov teeb liab, lwm qhov yog tsim los ntsuas tam sim no.
Lub pulse transformer muaj nyob rau hauv kev tswj thiab kev sib txuas lus circuits. Nws txoj hauj lwm yog hloov ceev ceev- hloov hluav taws xob pulses kom raug los ntawm ib lub voj voog mus rau lwm qhov thaum tswj kev ua haujlwm waveform. Hauv cov ntawv thov xws li rooj vag tsav tsheb rau IGBTs, MOSFET triggering, lossis siab -kev sib cais digital ceev, cov duab ntawm cov mem tes yog qhov tseem ceeb. Yog tias lub sij hawm nce qeeb qeeb, lossis yog tias lub waveform distorted, lub txais yuav hloov tsis raug. Tias yog vim li cas pulse transformers yog tsim los nrog kev tswj nruj ntawm kev xau inductance, coefficient sib txuas, thiab siab - zaus teb. Lawv tsis yog tsim los rau kev ruaj khov- lub xeev hloov hluav taws xob, tab sis rau kev coj tus cwj pwm tsis zoo.
Ib qho tam sim no transformer (CT), ntawm qhov tod tes, ua hauj lwm sib txawv kiag li. Hloov chaw xa cov cim, nws yog siv los txiav txim siab thiab ntsuas qhov hloov pauv tam sim no hauv cov tshuab hluav taws xob. Nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction ib yam nkaus, tab sis nws cov zis yog proportional rau tam sim no ntws los ntawm tus thawj conductor. Hauv kev lag luam tshuab, CTs tau siv dav rau kev ntsuas, kev tiv thaiv relays, thiab kev saib xyuas cov tshuab. Lawv qhov tseem ceeb ntawm kev tsim qauv yog qhov tseeb nyob rau hauv cov xwm txheej thauj khoom, linearity tshaj qhov kev txiav txim siab tam sim no, thiab kev nyab xeeb kev sib cais los ntawm siab -voltage kab.
Ib qho ntawm qhov sib txawv tseem ceeb tshaj plaws yuav pom meej thaum koj saib ntawm kev ua haujlwm. Lub pulse transformer feem ntau cuam tshuam nrog siab - zaus, luv luv - lub sijhawm teeb liab qhov twg lub sij hawm thiab waveform fidelity muaj teeb meem ntau dua li cov qib fais fab. Lub tshuab hluav taws xob tam sim no ua haujlwm ntawm lub zog zaus (50/60Hz) thiab xav tias yuav rov tsim dua qhov sib piv tam sim no kom raug nyob rau lub sijhawm ua haujlwm tas mus li.
Peb ib zaug tau tshuaj xyuas qhov kev tswj tsis tau zoo rau lub chaw tsim khoom siv hluav taws xob rov ua dua tshiab nyob rau sab hnub tuaj Asia uas lub tshuab hloov pauv hloov pauv hloov pauv nrog CT- zoo li cov qauv hauv kev hloov kho qauv. Lub kaw lus tsis poob tam sim ntawd. Hloov chaw, hloov maj mam lub sij hawm distortions sau nyob rau hauv lub rooj vag tsav tsheb teeb liab. Lub inverter khiav, tab sis hloov qhov poob tau nce ntau, ua rau overheating tom qab ob peb teev ua haujlwm. Qhov teeb meem thaum kawg tau taug qab mus rau qhov hloov pauv tsis muaj peev xwm khaws cov mem tes ceev ceev.
Kev xaiv cov khoom tseem ceeb yog lwm qhov sib txawv. Pulse transformers feem ntau siv ferrite cores optimized rau siab - zaus ua haujlwm nrog cov tub ntxhais poob qis. Tam sim no transformers, txawm li cas los xij, yog tsim los rau qhov tseeb thiab ruaj khov ntawm qhov tsawg zaus, feem ntau siv silicon steel lossis cov khoom sib nqus zoo sib xws nyob ntawm cov ntawv thov hauv chav kawm. Qhov sib txawv no ib leeg ua rau lawv tsis tsim nyog rau kev hloov pauv hauv feem ntau.
Winding tsim kuj qhia txog lawv cov hom phiaj sib txawv. Hauv pulse transformers, interwinding capacitance thiab to inductance yuav tsum tau txo kom tsawg los khaws cov teeb liab kev ncaj ncees. Nyob rau hauv tam sim no transformers, qhov tseem ceeb yog nyob rau hauv proportional raug thiab kev nyab xeeb nyob rau hauv qhov teeb meem txhaum cai, qhov twg loj tam sim no yuav ntws poob nthav. CTs feem ntau yog tsim los kom saturate nyob rau hauv ib qho kev tswj hwm los tiv thaiv cov cuab yeej txuas nrog, qhov kev hloov pauv mem tes yog tsim los kom tsis txhob muaj kev cuam tshuam hauv kev ua haujlwm ib txwm muaj.
Lwm qhov sib txawv tseem ceeb nyob ntawm seb lawv siv li cas hauv qhov system. Pulse transformers yog ib feem ntawm lub cev muaj zog-lawv cuam tshuam ncaj qha nrog cov khoom siv hloov pauv thiab tswj cov logic. Lub transformer tam sim no feem ntau yog ib feem ntawm kev saib xyuas lossis tiv thaiv txheej, pub cov ntaub ntawv ntsuas rau hauv meters lossis tiv thaiv relays. Ib qho cuam tshuam li cas lub kaw lus ua haujlwm; lwm tus saib seb qhov system coj li cas.
Los ntawm kev pom kev tsim khoom ntawm Wuxi Huipu Electronics Co., Ltd., cov txheej txheem tswj xyuas zoo kuj txawv. Pulse transformers yuav tsum tau kuaj waveform, inductance stability checks, thiab siab -frequency performance verification. Tam sim no transformers xav tau qhov kev ntsuas qhov tseeb qhov sib piv, ntsuas qhov yuam kev ntawm theem, thiab ntsuas lub nra hnyav raws li qhov sib txawv load. Txawm hais tias ob qho tib si yog cov khoom siv hlau nplaum, cov txheej txheem kev ntsuam xyuas qhia txog lawv lub luag haujlwm sib txawv hauv lub cev.
Cov kws tsim khoom qee zaum xav tias vim tias ob qho tib si siv tooj liab windings thiab cov hlau nplaum sib nqus, lawv nyob rau tib qeb. Nyob rau hauv kev muaj tiag, lawv nyob rau txawv design philosophies. Pulse transformers yog optimized rau ceev thiab teeb liab fidelity. Tam sim no transformers yog optimized rau kev ntsuas qhov tseeb thiab kev nyab xeeb.
Kev nkag siab qhov sib txawv no tsis yog kev kawm nkaus xwb - nws tiv thaiv - lub ntiaj teb kev ua tsis tiav. Hloov ib qho rau lwm tus, txawm tias cov lus qhia hluav taws xob zoo ib yam ntawm cov ntawv, tuaj yeem ua rau tus cwj pwm tsis zoo hauv hluav taws xob hluav taws xob lossis kev nyeem tsis raug hauv cov tshuab ntsuas.
Nyob rau hauv niaj hnub kev lag luam tsim, qhov chaw tswj cov tshuab thiab lub zog hluav taws xob sib xyaw ua ke, xaiv kom raug ntawm pulse transformers thiab tam sim no transformers yog qhov kev txiav txim me me nrog rau qhov loj. Nws txiav txim siab seb lub kaw lus teb puas yog, ntsuas kom raug, thiab ua haujlwm ntseeg siab dhau sijhawm.
