Tshuaj insulatorsPuas yog kev tswj hwm tshwj xeeb uas tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev sib kis cov kab sib kis. Nyob rau hauv thaum ntxov xyoo, insulators tau siv rau cov nqi hluav taws xob, thiab majy tsim mus rau hauv siab - voltage hlau txuas mus rau Insulators uas muaj Insulators tau dai rau ntawm ib kawg. Nws tau siv los ua kom cov kev ncua deb, feem ntau yog ua los ntawm iav lossis ceramics, thiab tau hu ua insulator. Insulators ua si ob lub luag haujlwm yooj yim hauv cov kab mob overhead kissead, uas pab txhawb nqa xov hlau thiab kev tiv thaiv tam sim no los ntawm rov qab mus rau hauv av. Ob lub luag haujlwm no yuav tsum tau lees tias. Insulators yuav tsum tsis swb vim muaj ntau yam kev nyuaj siab los ntawm kev hloov pauv ntawm ib puag ncig thiab hluav taws xob thauj khoom. Txwv tsis pub, insulator yuav tsis ua lub luag haujlwm tseem ceeb, thiab nws yuav ua rau lub neej pabcuam thiab ua haujlwm lub neej ntawm tag nrho cov kab.
Tshuaj insulator: Nws yog ib qho khoom uas kho thiab ncua cov hlau rau ntawm cov pej thuam hauv kev ua insulated. Feem ntau siv insulators rau cov hluav taws xob kis tau cov kab yog: Disc
Tus pas nrig tshem tawmthooj insulatorsCov. (1) plooj (cellalain insulators: cell cancers insulators muaj tus nqi siab, yuav tsum tau los xyuas cov xoom uas muaj zog.
Nyob rau hauv qhov kev tshwm sim ntawm xob laim thiab cov pa paug nrawm, hlua tso cov hlua khau yog nquag tshwm sim, thiab lawv tau tshem maj mam. (2) Cov tshuaj insulator iav: nws muaj xoom tus kheej - tawg, tab sis tus kheej - Tawg tawg tus nqi yog tsawg heev (feem ntau ob peb kaum txhiab). Tsis muaj kev kuaj xyuas yog xav tau rau kev saib xyuas. Thaum yus tus kheej - Tawg tawg ntawm cov iav txias, cov tshuab hluav taws xob uas muaj zog tshaj li 80% uas tseem tuaj yeem ua kom muaj kev nyab xeeb ntawm txoj kab. Yuav tsis muaj cov xwm txheej poob qis thaum ntsuas hluav taws xob thiab nrawm nrawm. Nws tau siv dav hauv chav kawm I thiab chav kawm II pollution. (3) Puas muaj Insulator: Nws muaj qhov zoo ntawm cov tshuaj tiv thaiv zoo, muaj zog dua, thiab tau siv dav dav hauv cov qib III thiab saum toj no.
Plooj (Insulators: Insulators feem ntau yog paub raws li lub pob (veneers) uas siv los txhawb nqa cov xov hlau. Insulators tuaj yeem ua kom muaj rwb thaiv kom txaus rau cov neeg saib xyuas, hla caj npab thiab yees. Nws yuav tsum tau tiv thaiv lub thauj hauv cov kev coj ntsug ntawm cov xaim thiab cov nro hauv kab rov tav thaum ua haujlwm. Nws tseem tau tiv thaiv lub hnub, nag, huab cua hloov thiab tshuaj corrosion. Yog li ntawd, insulators yuav tsum muaj ob qho hluav taws xob zoo thiab muaj kev zoo siv lub zog. Qhov zoo tshaj ntawm insulator yog qhov tseem ceeb heev rau kev ua haujlwm nyab xeeb ntawm txoj kab. Insulators tuaj yeem faib ua cov insulators, anti) kev xaiv tsa cov kab mob thiab cov insulators thiab insulators raws li lawv cov qauv. Raws li lub hom phiaj, nws tuaj yeem muab faib feem ntau muab faib ua peb pawg: kab insulators, cov tshuaj tiv thaiv insulators thiab bushings. Raws li cov ntaub ntawv ntawm insulator. Tam sim no muaj plooj (vencelain, iav thiab organic sib xyaw cov insulators. Cov insulators siv nyob rau hauv cov kab ua haujlwm feem ntau siv tus pin insulators, Rauv Insulators, PoFeltain Cross - Caj npab, Qws insulators thiab cov insulators thiab nro insulators thiab nro. Muaj ob hom hluav taws xob ua tsis tau hluav taws xob hauv insulators: grashover thiab tawg. Flasher tshwm sim nyob rau ntawm insulator insulator, thiab cov cim hlawv tuaj yeem pom, tab sis feem ntau cov kev ua haujlwm rwb thaiv tsev tsis ploj; Kev rhuav tshem tshwm sim sab hauv insulator, thiab kev tawm tawm tshwm sim los ntawm lub cev ceramic ntawm lub hau hlau thiab cov hlau taw. Insulators tej zaum yuav raug kaw tag nrho los ntawm kev sib. Rau qhov tawg, saib xyuas yuav tsum tau them los kuaj xyuas cov paug tawm thiab hlawv cov hlau taw. Txhawm rau tiv thaiv cov plua plav xws li ntab plua plav los ntawm cov insulator, ib txoj hauv kev yog tawg ntawm insulator, uas yog, creampage. Yog li no, qhov deb ntawm qhov chaw nyob yog nce, uas yog, qhov kev ncua deb uas tau tso tawm raws insulating saum npoo, uas yog, yog hu ua qhov tsis nrug deb.
Creepage nrug deb = deb deb / salfage voltage ntawm lub system. Raws li cov degree ntawm kev ua qias tuaj, qhov kev ncua deb yog feem ntau 31 hli / ib lub pob txha tsis muaj kuab paug. Qhov voltage tuaj yeem raug txiav txim ncaj qha raws li tus naj npawb ntawm insulators, feem ntau, 23 rau 500kv; 16 rau 330kv; 220kv 9; 110kv 5; Nov yog tus lej tsawg kawg nkaus, thiab yuav muaj ib lossis ob lossis ob qho ntxiv. Lub 500kV kis cov kab cia li siv plaub - cais tus neeg xyuas, yog, muaj plaub rau ib ntu, thiab 110kv siv ib qho ntxiv. Li 1 insulator yog 6 - 10kV, 35kv, 60kv kab tsis tsawg dua 5 daim, 11 insulators yog 220kv, 16 insulators yog 230V, 16kv; 28 Cov tshuaj insulators yog 500kv. Rau tus txiv neej insulators hauv qab 35kv, tsis muaj qhov sib txawv hauv cov naj npawb ntawm daim. 10KV siv cov kab ua haujlwm feem ntau siv 10 - 12m ib qho cement ncej thiab tus kav pin. Ncaj - kab deb ntawm cov ncej yog kwv yees li 70] 80m. Tsis muaj tus ncej hlau rau 10KV, tsuas yog ib tus ncej nrog peb siab - voltage kab rau nws. Ntau yam nyob rau hauv cov chaw nyob deb nroog; 35KV OVERHEAD LAGE feem ntau siv 15 - Meter ib leeg lossis ob daim xyooj me me (tseem siv cov npauj npaim me me) thiab 2,) 220kv yog twv txiaj ntsig hlau loj heev. 220kv overhead cov kab feem ntau siv cov hlau yees ntau dua 30 metres thiab cov hlua ntev ntawm cov npauj npaim. Ncaj - kab deb ntawm cov yees duab yog ntau tshaj 200 meters. Puas muaj insulators: kom ntseeg tau tias muaj kev nyab xeeb ntawm lub zog hluav taws xob thiab kev txhim kho kev ntseeg tau rau kev ntsuas hluav taws xob yog qhov ntsuas tau zoo los daws cov teeb meem no. Raws li cov khoom tshiab, silicone roj hmab composite insulator muaj qhov zoo me me, kev tiv thaiv - DAWB, thiab tau siv dav hauv 35kv thiab 110kv kab.
