Koj puas tau xav paub txog yuav ua li cas "huv" cov ntaub ntawv rwb thaiv tsev peb siv txhua hnub, xws li yas, roj hmab, thiab ceramics, yog? Hauv cov khoom siv hluav taws xob lossis siab -voltage cables, qhov zoo ntawm rwb thaiv tsev yog ncaj qha cuam tshuam rau kev nyab xeeb thiab ruaj khov, thiab "dielectric poob" yog qhov taw qhia tseem ceeb los ntsuas lawv cov kev ua haujlwm rwb thaiv tsev. Niaj hnub no, cia peb tham txog qhov tshwj xeeb "stethoscope" - ultra-low zaus dielectric poob tester, thiab saib seb nws "to taub" qhov tsawg-frequency "ntxhi" hauv cov khoom.
Dab tsi yog dielectric poob? Tus neeg ua txhaum ua rau cov khoom 'kub'!
Ua ntej delving rau hauv cov khoom siv kuaj, peb yuav tsum xub nkag siab tias "dielectric poob" yog dab tsi. Yooj yim muab, dielectric poob yog hais txog qhov tshwm sim uas lub dielectric hloov ib feem ntawm lub zog hluav taws xob rau hauv thermal zog nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob hloov pauv. Koj tuaj yeem xav txog tias thaum peb siv lub teb hluav taws xob rau cov khoom siv, cov nqi lossis cov polarity hauv cov khoom yuav txav los yog tig nrog kev hloov ntawm cov hluav taws xob. Thaum lub sijhawm txheej txheem no, yuav muaj qee qhov "kev sib txhuam" thiab "tsis kam", thiab cov kev poob zog no hu ua dielectric poob.
Lub dielectric poob tsis zoo dua nrog ntau dua lossis tsawg dua, tab sis yuav tsum tau tswj hwm hauv qhov tsim nyog. Kev ploj ntawm dielectric ntau dhau txhais tau hais tias cov khoom siv yuav ua kom muaj cua sov hnyav thaum lub sijhawm ua haujlwm, ua rau muaj kev laus, thiab txawm tias tawg, cuam tshuam rau lub neej ntev thiab kev nyab xeeb ntawm cov khoom siv. Piv txwv li, nyob rau hauv lub rwb thaiv tsev txheej ntawm high -voltage cables, ntau dhau dielectric poob tuaj yeem ua kom lub rwb thaiv tsev laus, ua kom cov dej xau tam sim no, thiab thaum kawg ua rau lub rwb thaiv tsev tsis ua haujlwm.
Lub ntsiab lus ntawm "ultra-low zaus": vim li cas ho tsis zoo dua kom siab dua?
Tej zaum koj yuav nug, vim li cas nws yog "ultra-tsawg zaus"? Nyob rau hauv lub xyoo ntawm kev xyaum ntawm Wuhan Ultra High Voltage Power Technology Co., Ltd., peb tau pom tias rau ntau lub siab - cov ntaub ntawv hluav taws xob rwb thaiv tsev, ua qhov kev sim dielectric poob hauv ultra- tsawg zaus ntau (feem ntau qis dua 0.1Hz) tuaj yeem cuam tshuam txog kev hloov pauv ntawm cov ntaub ntawv nyob rau hauv ntev - lub sijhawm ua haujlwm tsis zoo, tshwj xeeb tshaj yog qee qhov kev ua haujlwm tsis zoo.
Kev kuaj xyuas qhov tsis xws luag thaum ntxov: Ntau yam khoom siv tsis xws luag, xws li npuas me me, impurities, ya raws nkag, thiab lwm yam, yuav tsis pom tseeb ntawm cov zaus siab, tab sis ntawm ultra- zaus tsawg, lawv cov kev hloov pauv yuav pom tau yooj yim dua thiab yooj yim dua los txheeb xyuas.
Simulate ntev - lub sijhawm ua haujlwm: Hauv cov tshuab hluav taws xob tiag tiag, lub zog zaus (50Hz lossis 60Hz) yog lub hauv paus, tab sis cov khoom siv rwb thaiv tsev yuav hloov nrog lub sijhawm thiab ib puag ncig hloov pauv. Ultra low zaus xeem tuaj yeem ua rau qee qhov zoo dua simulate cov yam ntxwv poob ntawm cov khoom nyob rau hauv ntev - lub sij hawm thiab cov hluav taws xob nyuaj, thiab kwv yees lawv cov kev ua tau zoo yav tom ntej.
Tsis suav nrog siab - zaus cuam tshuam: Qee qhov kev poob ntawm cov zaus siab yuav yog vim cov lus teb ntawm cov khoom siv, uas tsis zoo ib yam li lub tshuab hluav taws xob poob ntawm lub zog tiag tiag. Ultra low zaus kuaj pab peb tshem tawm qhov cuam tshuam ntawm qhov siab -frequency effect thiab tsom ntau dua rau qhov poob tiag tiag.
Dab tsi yog qhov 'tom qab qhov xwm txheej' uas cuam tshuam rau dielectric poob?
Muaj ntau ntau "kev zais cia" hauv cov ntaub ntawv, thiab muaj ntau yam uas cuam tshuam rau dielectric poob, feem ntau suav nrog:
Cov khoom ntawm cov khoom nws tus kheej: cov qauv molecular, polarity, thiab tus nqi thauj mus los ntawm cov khoom sib txawv yog qhov sib txawv, uas ncaj qha txiav txim siab txog lawv qhov kev poob qis hauv lub cev.
Kub: Ib qho kev nce hauv qhov kub thiab txias feem ntau ua rau lub zog txav ntawm cov nqi thiab ua rau qhov poob ntawm dielectric.
Humidity: Cov dej noo yog "tus yeeb ncuab" ntawm dielectrics, vim nws ua rau cov khoom siv hluav taws xob ntau ntxiv, yog li ua rau qhov poob ntawm dielectric.
Lub zog hluav taws xob: Hauv qee qhov ntau, raws li lub zog hluav taws xob nce, qhov dielectric poob kuj yuav nce ntxiv.
Zaus: Raws li tau hais los saum no, cov txheej txheem teb ntawm cov ntaub ntawv sib txawv ntawm cov zaus sib txawv, thiab cov dielectric poob kuj yuav txawv heev.
impurities thiab tsis xws luag nyob rau hauv cov ntaub ntawv: npuas me me, tawg, impurity hais, thiab lwm yam yuav ua tau rau tsub kom tsub zuj zuj, ua zog poob.
Cov lus zais ntawm lub stethoscope: lub hauv paus ntsiab lus ua haujlwm ntawm ultra-low zaus dielectric poob tester
Lub ultra-low zaus dielectric poob tester ua haujlwm li cas? Nws ua haujlwm zoo li qhov tseeb "stethoscope" los ntawm kev siv qhov ruaj khov ultra- tsawg zaus AC voltage thiab ntsuas qhov sib txawv ntawm theem tam sim no thiab qhov hluav taws xob ntws los ntawm cov khoom ntsuas.
Kev siv hluav taws xob: Lub ntsuas hluav taws xob tsim hluav taws xob qis qis ultra- tsis tshua muaj zaus AC voltage thiab siv rau cov qauv kuaj.
Kev ntsuas tam sim no: Tib lub sijhawm, lub ntsuas yuav ntsuas qhov ntsuas tam sim no los ntawm cov qauv ntsuas.
Xam cov theem sib txawv: Qhov tseem ceeb yog tias nws suav cov theem sib txawv ntawm qhov siv hluav taws xob thiab ntsuas tam sim no (feem ntau yog sawv cev los ntawm tg δ lossis tan δ, uas yog tangent ntawm lub dielectric poob lub kaum ntse ntse).
Tau txais tus nqi poob: Raws li ntsuas qhov ntsuas hluav taws xob, tam sim no, thiab theem sib txawv, ua ke nrog tus nqi capacitance ntawm cov khoom, qhov dielectric poob tangent (tg δ) thiab dielectric tas li tuaj yeem xam.
Wuhan Ultra High Voltage Fais Fab Technology Co., Ltd. muaj kev sib sau ua ke hauv daim teb no thiab tau cog lus los muab siab -precision thiab siab stability ultra- tsawg zaus dielectric poob kev sim daws teeb meem.
Yuav ua li cas kom auscultation raug dua? Master cov txuj ci no!
Txhawm rau kom tau txais cov ntaub ntawv muaj txiaj ntsig ntau dua los ntawm ultra- tsis tshua muaj zaus dielectric kev sim, peb tuaj yeem pib los ntawm cov hauv qab no los ua "auscultation" ntau dua thiab muaj txiaj ntsig:
Xaiv qhov kev sim ntau zaus: Xaiv qhov tsim nyog ultra- cov ntsiab lus ntsuas zaus tsawg raws li cov khoom siv kuaj thiab cov xwm txheej siv tiag tiag. Piv txwv li, zaus xws li 0.01Hz, 0.02Hz, 0.05Hz, thiab 0.1Hz feem ntau yog siv.
Tswj ib puag ncig yam tseem ceeb: Qhov kub thiab av noo ntawm qhov ntsuas qhov chaw muaj qhov cuam tshuam loj rau kev ntsuas ntsuas. Nws yog ib qho tsim nyog yuav tau ua qhov kev ntsuam xyuas nyob rau hauv qhov kub thiab txias ib puag ncig thiab khaws cov ntaub ntawv.
Xyuas kom meej cov qauv zoo: Qhov saum npoo smoothness, thickness uniformity, thiab pom qhov tsis xws luag ntawm cov qauv kuaj yuav tag nrho cov cuam tshuam rau kev ntsuas. Xyuas kom meej tias tus qauv ua tau raws li qhov yuav tsum tau ua.
Kev paub zoo hauv kev khiav hauj lwm cov cuab yeej: Master ntau yam kev ua haujlwm thiab cov kauj ruam ua haujlwm ntawm lub cuab yeej, nkag siab txog kev sim ntsuas hauv ntau hom, thiab zam kev ua haujlwm tsis raug.
Kev tsom xam ntawm cov ntaub ntawv: Tsis txhob saib tus nqi TG δ hauv kev sib cais. Kev txiav txim siab ntau dua tuaj yeem ua tau los ntawm kev sib txuas cov dielectric tas li ntawm cov khoom, qhov poob nkhaus ntawm ntau zaus, thiab muab piv nrog cov ntaub ntawv keeb kwm.
Tsis tu ncua calibration ntawm cov twj paj nruag: Yuav kom ntseeg tau qhov tseeb ntawm kev ntsuas ntsuas, nws yog ib qho tsim nyog yuav tsum tsis tu ncua calibrate lub ultra- tsawg zaus dielectric poob tester. Wuhan Ultra High Voltage Fais Fab Technology Co., Ltd. muab cov cuab yeej kev ntsuas kev ntsuas thiab kev saib xyuas kom ntseeg tau tias koj cov cuab yeej ua haujlwm ib txwm ua haujlwm zoo tshaj plaws.
Lwm daim ntawv thov thiab txuas ntxiv: Ntau tshaj qhov ntawd!
Daim ntawv thov ntau yam ntawm ultra- tsis tshua muaj zaus dielectric tsis kuaj yog dav heev. Nws tsis yog tsuas yog ib qho tseem ceeb ntawm kev ntsuas kev ua tau zoo ntawm cov ntaub ntawv rwb thaiv tsev, tab sis kuj tseem ua lub luag haujlwm tseem ceeb hauv cov haujlwm hauv qab no:
Kev kuaj kab hluav taws xob siab: siv los ntsuas kev noj qab haus huv ntawm cov kab hluav taws xob rwb thaiv tsev, kwv yees lub neej ntev, thiab qhia cov phiaj xwm kev saib xyuas.
