Muaj kev xav dav dav tias tus nqi siab yeej ib txwm zoo rau tus neeg muag khoom thaum tus nqi qis ib txwm zoo rau tus neeg yuav khoom. Nyob rau hauv lub ntiaj teb no ntawm hluav taws xob insulators, li cas los xij, qhov no tsis tas yuav muaj tseeb. Ntawm no, tus nqi tau txais ntawm ib qho insulator yog qhov tseeb tsawg dua qhov tseem ceeb tshaj qhov kev ua tau zoo thiab kev pab cuam lub neej nws yuav muaj. Yog tias tus nqi siab zoo dua kwv yees qhov ua tau zoo ntev - lub sijhawm ua haujlwm, qhov no yuav zoo rau tus neeg yuav khoom thiab tus muag khoom.
Warren Buffet ib zaug hais tias, "tus nqi yog qhov koj them rau ib yam dab tsi; tus nqi yog qhov koj tau txais rov qab". Nyob rau hauv cov ntaub ntawv ntawm insulators, tau txais tus nqi (piv txwv li tus nqi) muaj peev xwm ua pov thawj kuj me me piv rau tag nrho cov nqi ntawm lub neej, uas yuav ua tau ntau zaus ntau dua. Tus nqi tiag tiag ntawm ib qho insulator nyob rau hauv qhov zoo npaum li cas cov nqi qis hauv lub neej no tuaj yeem tswj tau nyob rau hauv qhov kev txwv.
Ib qho insulator yog ib qho kev tivthaiv tswj kev ua haujlwm ntawm cov cuab tam kim. Thaum cov insulators feem ntau suav txog tsuas yog 5 mus rau 10 feem pua ntawm tag nrho cov nqi tsev rau cov kab hluav taws xob tshiab lossis cov chaw ua haujlwm substation, cov teeb meem nrog cov ignsulators feem ntau yog qhov ua rau tsis muaj kev puas tsuaj. Ntxiv mus, vim lawv cov naj npawb thiab cov tswv yim tseem ceeb, lawv kuj yog ib feem uas yuav tsum tau kuaj xyuas tsis tu ncua thiab muaj peev xwm kho cov nqi kho mob siab.
Nyob rau hauv saib ntawm cov saum toj no, nws yog tsim nyog los soj ntsuam dab tsi tshwm sim rau tus nqi thiab zoo ntawm insulators nyob rau hauv lub xyoo dhau los.
Nyob rau hauv nws phau ntawv 1988, 'INSULATORS FOR HIGH VOLTAGES', British insulator expert, John Looms, piv cov nqi ntawm insulators thaum lub sij hawm nrog cov nqi ntau xyoo dhau los. Nws pom tias cov no tau nyuam qhuav hloov pauv ntawm cov lej ntawm qhov sib npaug ntawm qhov hnyav, txawm tias muaj ntau xyoo ntawm kev nce nqi. Nws xaus lus tias cov insulators tau ua ib qho pheej yig heev, tshwj xeeb tshaj yog tias ib tus tau tso cai rau lawv qhov tseem ceeb npaum li cas rau kev xa hluav taws xob thiab kev faib tawm.
Xyoo 1990s tau cim qhov pib ntawm kev ua yeeb yam zoo nkauj rau kev lag luam xa hluav taws xob feem ntau thiab rau kev lag luam insulator tshwj xeeb. Ua ntej, raws li ntau thiab ntau cov khoom siv tau dhau los ua neeg ntiag tug thiab de- tswj hwm los tsim kev sib tw, yav dhau los - kev sib raug zoo ntawm cov khoom siv hluav taws xob thiab cov chaw tsim hluav taws xob hauv zos tau pib yaj. Dheev, cov khoom siv hluav taws xob tsis kam txhawb cov neeg xa khoom hauv zos yog tias qhov no txhais tau tias them tus nqi siab dua. Ntxiv rau qhov kev sib tw nce siab yog qhov tseeb tias OEM cov neeg siv khoom loj tau pib tsim cov khoom siv thoob ntiaj teb kom tau txais cov insulators uas lawv xav tau los ntawm cov txiaj ntsig zoo tshaj plaws thoob ntiaj teb.
Thaum kawg, kev loj hlob ntawm kev lees txais cov cuab yeej siv hluav taws xob sib xyaw pib txij li nruab nrab mus rau xyoo 1990s tau tsim cov qauv tshiab rau kev lag luam uas tso cai rau tus nqi tsav tsheb txawm tias qis dua. Cov insulators no tuaj yeem tsim nrog kev tuav tsawg dua thiab cov ntsiab lus ua haujlwm ntau dua li cov plooj (porcelain) lossis iav sib npaug. Tus naj npawb ntawm cov neeg sib tw kuj tau nce ntau vim nws tau yooj yim dua rau cov neeg xa khoom tshiab nkag mus rau cov khoom siv hluav taws xob sib xyaw ua ke piv rau kev tsim cov plooj (porcelain) tshiab lossis toughened iav insulator cog.
Ua ke, tag nrho cov kev txhim kho concurrent no ua rau muaj kev nyuaj siab rau tus nqi ntawm insulators.
Xyoo 2009, Prof. Liang Xidong ntawm Tsinghua University hauv Beijing - tam sim no kuj Convenor ntawm IEC Ua Haujlwm Pab Pawg ntawm kev hloov kho cov qauv insulator - suab ceeb toom txog dab tsi yuav tshwm sim yog tias tus nqi ntawm cov insulators txuas ntxiv poob qis. Nws tau sau tseg, piv txwv li, tias tus nqi ntawm silicone insulators hauv Suav teb rau daim ntawv thov ntawm 110 txog 500 kV systems thaum lub sijhawm tau dhau los ua qis dua thaum pib siv. Thaum kev lag luam ntawm nplai hauv kev tsim khoom tau pab txo qis cov nqi tsev, qhov tseem ceeb tom qab tus nqi poob yog kev sib tw hnyav ntawm cov tuam txhab tshiab thiab tsim. Nws pom qhov txaus ntshai. Nrog rau cov nqi poob qis, cov tuam txhab lag luam yuav tsum nrhiav txoj hauv kev los txiav cov nqi los ntawm kev ua kom zoo dua cov ntaub ntawv thiab tej zaum yuav txo qis qhov kev ua haujlwm ntawm lawv cov insulator tsim. Tam sim no, lub hom phiaj tseem ceeb tau dhau los ua tsis tau tsim cov insulator uas muaj teeb meem ntau xyoo - kev pabcuam dawb tab sis yog ib qho uas yuav raug nqi tsawg dua los tsim khoom tseem tseem dhau tag nrho cov kev xeem uas xav tau hauv cov qauv.
Los ntawm ib ncig ntawm 2014/15, cov khoom siv hluav taws xob hauv Tebchaws Europe thiab lwm qhov tau pib qhia txog qhov tsis sib xws hauv qee qhov insulators hauv lawv cov khoom muag. Kuj tseem muaj qhov ua tsis tiav tau tshaj tawm los ntawm thaj chaw. Raws li qhov no, cov chaw kuaj sim sai sai tau pib tau txais ntau thiab ntau qhov kev thov rau cov uas tsis yog- cov qauv ntsuas raws li cov neeg siv khoom tshwj xeeb.
Cov lus nug yog li no tshwm sim yuav ua li cas zoo tshaj plaws kom muaj kev sib npaug ntawm tus nqi thiab zoo. Qhov no yog lub hauv paus rau kev txhim khu kev qha thiab ua haujlwm tau zoo ntawm txhua lub tshuab hluav taws xob. Tab sis los teb cov lus nug no ib tug yuav tsum xub paub qhov txawv ntawm qhov zoo thiab tsis zoo insulators. Piv txwv li, dab tsi yog qhov zoo ntawm cov khoom siv insulator?
Raws li xibfwb Liang, "kev ua tau zoo yuav tsum raug txiav txim los ntawm kev ua haujlwm insulator ntev dua - lub sijhawm ua haujlwm ntawm lub network - ib yam uas tsis yooj yim rau kev ntsuam xyuas ua ntej thaum lub insulator yog tsim thiab yuav los ntawm tus neeg siv khoom. Tab sis, qhov no tsuas yog txiav txim los ntawm cov txiaj ntsig los ntawm kev sim. Yog tias lub insulator dhau qhov kev sim, nws feem ntau yog cov khoom tsim nyog. Tab sis, raws li kev kwv yees tsis raug, nws yog ib qho kev sib tham txog qhov tseeb. ntev - kev ua tau zoo ua ntej nws yuav tsum tau muab tso rau hauv kev ua haujlwm tsuas yog nyob ntawm cov qauv tam sim no thiab nws yog qhov nyuaj tshwj xeeb rau kev paub qhov zoo ntawm silicone insulator los ntawm ib qho uas tsuas yog dhau tag nrho cov kev xeem uas yuav tsum tau ua.
Liang xaus lus tias tus nqi ntawm 35-220 kV silicone insulators hauv Suav teb tau raug txiav ntau dhau thaum tus nqi ntawm 500 kV AC units kuj tseem poob qis heev. Yog li ntawd nws tau dhau los ua qhov tseem ceeb rau kev siv cov qauv ntsuas siab dua los ua ib txoj hauv kev los pab kwv yees kev ua tau zoo mus sij hawm ntev. Nws kuj tau cia siab tias kev sib ntaus sib tua ntawm tus nqi thiab qhov zoo yuav tsis txuas ntxiv mus rau cov insulators rau cov kab kev sib tw zoo xws li ± 500 kV lossis ± 800 kV HVDC kab uas muaj peev xwm kis tau tus mob yog 3000 MW thiab 6400 MW feem - tsis yog rau 1000 kV UHV AC kab.
Cov neeg siv thiab cov neeg tsim khoom ob leeg muaj lub hom phiaj tib yam thaum kos npe rau daim ntawv cog lus muag, uas yog txhawm rau nruab ib txoj kab tshiab lossis substation nrog insulators uas yuav ua tau yam tsis muaj teeb meem ntau xyoo. Tab sis muaj cov kev sib tw rau qhov kev ua yeeb yam keeb kwm no vim ntau thiab ntau tus neeg muag khoom pom lawv tus kheej sib tw raws li tus nqi. Hais tias ib qho kev lag luam sab hauv, "muaj kev nyuaj siab tsuas yog kom muaj sia nyob. Tsis tsim nyog tus nqi niaj hnub no tuaj yeem txo cov nqi tau los rau cov neeg ua haujlwm hauv kab sib chaws. Tab sis lawv tuaj yeem ua rau tus nqi siab heev hauv txoj kev, tshwj xeeb tshaj yog tias cov chaw tsim khoom insulator yuav tsum tau ua kom zoo downward kom nyob twj ywm kev sib tw".
Cov lus xaus tseem ceeb: cov neeg siv kawg yuav tsum tau siv sij hawm ntev - lub sij hawm saib thaum muas ib feem uas yog raws li lub tswv yim rau kev nyab xeeb thiab txhim khu kev qha kev khiav hauj lwm ntawm lub hwj chim network raws li ib tug insulator. Qhov ntawd txhais tau tias tus nqi qis yuav tsum tsis txhob yog lub hauv paus rau kev xaiv ib tus neeg muag khoom dua lwm tus. Txawm hais tias qee zaum tsis raug suav hais tias yog cov khoom lag luam yooj yim nrog cov ntsiab lus thev naus laus zis sib piv, qhov tseeb yog tias cov hluav taws xob insulators tuaj yeem ua pov thawj qhov tsis muaj zog txaus ntawm txhua lub zog. Kev ua haujlwm tsis zoo yuav ua rau muaj kev puas tsuaj txawm tias qhov zoo tshaj plaws - cov kab thiab cov chaw nres tsheb ua rau muaj teeb meem thiab ua rau muaj kev cuam tshuam ntau zaus lossis cov nqi kho mob siab - lossis ob qho tib si. Qhov no yog qhov tseeb undeniable uas elevates lub tswv yim tseem ceeb ntawm cov insulator mus rau ib theem deb nyob rau hauv ntau tshaj ntawm nws kuj me me feem ntawm tag nrho cov peev nqi.
Nws yog ib lo lus nug tiag tiag ntawm lub hauv paus ntsiab lus twg yog qhov tseem ceeb tshaj thaum yuav: '' luv- lub sij hawm nce nrog ua tau ntev - mob ntev '' lossis '' luv - lub sij hawm mob ntev - lub sij hawm nce ''.
