Feb 03, 2026 Tso lus

Koj puas tau xav paub txog yuav ua li cas cov khoom siv hluav taws xob loj, xws li transformers, cables, thiab lwm yam, ua kom lawv txoj haujlwm "hmoov" thiab tiv thaiv "mob" tam sim ntawd? Niaj hnub no, cia peb tham txog ib lub cuab yeej tseem ceeb uas ua lub luag haujlwm ntawm "tus saib xyuas kev noj qab haus huv" hauv lub zog hluav taws xob -dielectric poob ntsuas ntsuas. Nws yog tus pab cuam muaj zog hauv kev nkag siab txog "kev noj qab haus huv" ntawm cov ntaub ntawv rwb thaiv tsev.

Dielectric Loss Tester

Dab tsi yog dielectric poob? Vim li cas nws thiaj tseem ceeb?
Cias muab, dielectric poob, los yog hu ua "dielectric poob", yog hais txog qhov tshwm sim nyob rau hauv uas ib tug dielectric converts ib feem ntawm hluav taws xob zog rau hauv thermal zog nyob rau hauv qhov kev txiav txim ntawm ib tug alternating hluav taws xob teb. Xav txog, ib yam li ib tug neeg uas tsis nco qab tawm hws thaum lawv ntshai, cov ntaub ntawv rwb thaiv tsev tuaj yeem "kub" hauv qab qhov kev txiav txim ntawm hluav taws xob.
Lub℃ntawm "cua sov", uas yog, qhov loj ntawm dielectric poob, ncaj qha cuam tshuam txog kev laus, cov ntsiab lus noo noo, impurities hauv cov khoom siv rwb thaiv tsev, thiab tej zaum yuav qhia tau tias muaj kev pheej hmoo tawg. Yog li, kev ntsuas qhov tseeb ntawm dielectric poob zoo li ua "kev kuaj xyuas kev noj qab haus huv" ntawm cov khoom siv hluav taws xob, uas tuaj yeem txheeb xyuas cov teeb meem raws sijhawm thiab tiv thaiv lawv ua ntej lawv tshwm sim.

 

Dab tsi yog "culprits" uas cuam tshuam rau dielectric puas?
Dielectric poob tsis yog tus lej yooj yim, nws tuaj yeem cuam tshuam los ntawm ntau yam:
Kub: Raws li qhov kub thiab txias, molecular motion intensifies, thiab dielectric poob feem ntau nce raws li.
Humidity: Moisture yog "tus yeeb ncuab ntuj" ntawm cov ntaub ntawv rwb thaiv tsev, thiab nws ua rau kom dielectric poob zoo heev tom qab nqus dej noo.
Lub zog hluav taws xob: Hauv qee qhov ntau, qhov hluav taws xob muaj zog dua, qhov siab dua qhov dielectric poob.
Cov khoom siv rwb thaiv tsev nws tus kheej: hom, purity, thiab qib ntawm kev laus ntawm cov khoom txhua tus txiav txim siab nws qhov kev poob qis hauv lub cev.

 

Leej twg tuaj yeem pab peb ntsuas 'dielectric poob? --Wuhan UHV Power Technology Co., Ltd. yog lub luag haujlwm rau nws lub zog!
Thaum nws los txog rau kev tshaj lijKev ntsuas dielectric poobcov cuab yeej, Wuhan UHV Power Technology Co., Ltd. yog qhov tsis tseem ceeb. Lawv tsim dielectric poob ntsuas cov cuab yeej muaj npe nrov hauv kev lag luam rau lawv qhov siab precision, ruaj khov, thiab yooj yim siv. Cov cuab yeej siv no feem ntau siv cov qauv ntsuas kev ntsuas siab tshaj, uas tuaj yeem ntsuas qhov ntsuas dielectric poob tangent (tan δ) ntawm cov khoom siv hluav taws xob rwb thaiv tsev ntawm qhov sib txawv voltage.

 

Yuav ntsuas qhov poob dielectric li cas?
Cov txheej txheem ntawm kev ntsuas dielectric poob yog qhov tseeb "powering on" lub cuab yeej thiab tom qab ntawd "mloog" rau nws "lub plawv dhia". Tshwj xeeb, nws yog los txuas covdielectric poob ntsuas ntsuasmus rau cov khoom siv kuaj (xws li transformers, transformers, cables, thiab lwm yam), siv ib tug tej yam AC voltage, thiab ces lub ntsuas yuav ntsuas qhov tam sim no ntws los ntawm cov ntaub ntawv rwb thaiv tsev thiab xam cov tsis xws li dielectric poob thiab capacitance. Los ntawm kev tshuaj xyuas cov kev hloov pauv ntawm cov kev txwv no, peb tuaj yeem ntsuas qhov "kev noj qab haus huv" ntawm rwb thaiv tsev.
Lub hauv paus ntsiab lus tseem ceeb: Ntsuas cov theem thiab amplitude ntawm tam sim no, thiab xam cov tangent ntawm lub dielectric poob lub kaum sab xis.
Cov cuab yeej tseem ceeb: Lub siab - precision thiab dav dielectric poob ntsuas ntsuas yog lub hauv paus.
Cov ntsiab lus ua haujlwm: Ua kom muaj kev ruaj ntseg ntawm qhov chaw sim, txhim khu kev qha kev sib txuas, thiab ua raws li cov txheej txheem kev ua haujlwm.

 

Koj puas xav ua kom zoo dua hauv kev ntsuas dielectric poob?
Kom tau txais qhov tseeb dua thiab muaj txiaj ntsigKev ntsuas dielectric poobcov ntaub ntawv, koj tuaj yeem pib los ntawm cov ntsiab lus hauv qab no:
Xaiv cov cuab yeej tsim nyog: Raws li qhov ntsuas hluav taws xob thiab qhov tseeb ntawm cov khoom siv kuaj, xaiv qhov kev ua tau zoo sib xws dielectric poob tester.
Kev ua haujlwm tau zoo: Ua kev sim nruj me ntsis raws li lub teb chaws cov qauv lossis cov qauv kev lag luam kom txo tau tib neeg kev ua yuam kev.
Kev txheeb xyuas cov ntaub ntawv thiab kev sib piv: Kev sib koom ua ke cov ntaub ntawv keeb kwm thiab cov khoom siv ua haujlwm rau kev txheeb xyuas dav tuaj yeem txiav txim siab cov khoom siv tau zoo dua.
