1. Lub hom phiaj thiab hom
High-voltage kab disc-hom raug rho tawm insulators (txuas mus rau hu ua insulators) yog siv rau cov rwb thaiv tsev thiab cov xaj hluav taws xob hauv cov hluav taws xob high-voltage overhead kis thiab xa cov kab. Ib pawg ntawm cov kab hluav taws xob yog sib dhos rau ntawm txoj kab ntawm kev sib txawv ntawm theem hluav taws xob. Cov rwb thaiv tsev tau muab faib ua hom zoo tib yam thiab cov pa phem-raws li lawv qhov chaw siv thiab thaj chaw. Cov insulators zoo tib yam haum rau cov chaw dav dav. Yog tias cov naj npawb ntawm cov insulators tau nce ntau ntxiv, cov pa phem flashover kev ua tau zoo dua tuaj. Cov kuab paug plua plav tsis ua hauj lwm yog muab faib mus rau hauv lub thawv tswb hom thiab ob-txheej txheej lub kaus mom raws li lawv cov qauv. Muaj kuab paug rau cov rwb thaiv tsev yog tsim nyog rau cov hmoov av hauv kev lag luam, tshuaj lom neeg kev lag luam, saline-alkali, chaw ntug hiav txwv thiab pos huab. Cov qauv sib txawv yog qhov zoo tshaj plaws rau cov rwb thaiv kev ua qias tuaj Cov kev siv yuav tsum txiav txim siab tom qab kev sim ua ntej.
2. Taw qhia txog cov qauv
Cov insulators raug tshem tawm yog ua los ntawm cov chaw ntim ntawm pob zeb thiab cov plaub hau cap hlau ua los ntawm Portland cement no.525, cov xuab zeb porcelain lossis quartz xuab zeb kua nplaum. Ib txheej txheej tsis ntwm ntawm txheej tsis yog thov rau saum npoo ntawm hlau hau thiab hlau taw hauv kev sib cuag nrog cov nplaum. Elastic padding nyob rau sab saum toj ntawm taw steel. Qhov saum npoo ntawm cov plooj (venice) feem ntau dawb ci. Lub ntsej muag ci ci ci lossis xiav ntoo tshauv iav tuaj yeem siv tau raws li qhov xav tau.
3. Qhov saum npoo ntawm cov taw hlau yog txhua qhov kub-dip galvanized.
Lub laub-rub elastic xauv tus pin ntawm kheej kheej kev sib txuas qauv muaj ob hom W-hom thiab R-hom. Lawv tau ua los ntawm tooj liab, uas muaj zoo elasticity thiab corrosion tsis kam, thiab yog yooj yim rau disassemble thiab sib sau ua ke. Slotted cylindrical tus pin thiab hump-puab faib tus pin, tus qub yog kub dip galvanized, thiab tom kawg yog ua los ntawm steel. Qhov saum toj no elastic ntsuas phoo. Round coj pins thiab lwm qhov chaw tau muab cov khoom ua tiav tiav
Cov vaj tsev zoo nkauj insulator muaj qhov sib txawv nruab nrab ntawm cov npoo ntawm cov kaus pawg, tshwj xeeb tshaj yog XP-70 thiab X-45 hom kab hluav taws xob, tus nplawm sab yog qhov dav, yooj yim ntxuav, thiab steel ko taw pob lub taub hau feem ntau nthuav tawm ntawm pawg pab pawg porcelain. Cov. Yooj yim rau kev ua haujlwm.
Cov txheej txheem ob txheej txheej muaj cov plua plav uas tsis muaj zog tiv thaiv, kev qhib lub kaus lub cev, du thiab edgeless hauv pab pawg, tsis muaj plua plav cov pa paug siab, thiab ua haujlwm zoo tu tus kheej hauv cov cua thiab nag. Tswb-hom pa phem-tiv thaiv kev tshem tawm insulator. Nws nqus cov yam ntxwv ntawm European, Asmeskas thiab Japanese cov tshuaj tiv thaiv huab tiv thaiv huab cua, thiab siv lub sijhawm sib txawv ntawm cov dej noo sab hauv thiab sab nraum lub kaus thiab lub siab tsis muaj zog nyob hauv qab lub kaus. Qhov kev tiv thaiv kev ua qias tuaj muaj qhov zoo. Cov txiaj ntsig ntawm ntau qhov kev sim ua kom muaj paug qias neeg tau ua pov thawj tias kev ua qias tuaj xob laim xob laim Abi tuaj yeem nce ntxiv li 20-50% piv nrog cov ntxig hluav taws xob hauv tib theem.
