Thaum qhov voltage siab tshaj 66 kV, lub sij hawm "siab -voltage ceramic insulator" tsis yog hais txog kev faib khoom lag luam; hloov pauv, nws tau hloov zuj zus mus rau hauv kev qhuab qhia engineering. Hauv kev sib piv rau nruab nrab - thiab qis-voltage ceramic insulators, uas feem ntau feature pin- hom thiab xaim - hom configurations, siab -voltage{1}}voltage- peb cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob ncua kev kawm ntawv discs, ntev-rod ceramic insulators, thiab post{10}} hom kev txhawb nqa txhua series muaj nws tus kheej tsim qauv, tsis ua hauj lwm hom, thiab kev tsim nyog cov qauv no piav qhia txog qhov tseem ceeb uas yuav tsum tau coj mus rau hauv tus account thaum lub sij hawm xaiv.
Cap-thiab-Pin Suspension Discs: Cov Neeg Ua Haujlwm Sib Txuas
Cov txheej txheem kis tau tus mob siv cov porcelain discs txuas nrog tus pin- thiab - qhov (socket) kawg npog; Qhov kev daws teeb meem no tau raug ntsuas raws li IEC 60305 thiab ANSI C29.2 tus qauv. Qhov dav dav ntawm cov plooj (porcelain discs) yog 254, 280, thiab 320 hli, nrog rau qhov sib txuas ntawm 146, 155, thiab 170 hli, raws li. Electromechanical tsis ua hauj lwm loads tau muab faib ua cov qib predefined: 70, 120, 160, 210, 300, 400, thiab 530 kN. Tus naj npawb ntawm cov plooj (porcelain discs) hauv ib txoj hlua nce nrog qhov system voltage thiab muaj kuab paug hnyav - feem ntau 7-9 discs rau 110 kV systems, 13-14 discs rau 220 kV systems, thiab 25 lossis ntau dua discs rau 500 kV systems. Cov pa phem-resistant (fog-resistant) porcelain discs, txawm li cas los xij, xav tau ntau dua qhov chaw teeb tsa, nrog rau qhov kev ncua deb.
Ntev -Qws thiab Chaw Nres Nkoj Post Porcelain
Ntev -rodporcelain insulatorshloov disc- hom insulator cov hlua nrog ib qho khoom tseem ceeb, yog li tshem tawm tus pin-kab sib koom ua ke qhov chaw noo noo-vim ua tsis tiav yuav tshwm sim. Xws li cov insulators tau siv dav hauv lub hwj chim- engineering tej yaam num thoob plaws lub teb chaws Yelemees thiab Central Europe, thiab kuj yog feem ntau siv nyob rau hauv siab -voltage DC kis kab. Chaw nres tsheb -mounted post insulators ua raws li IEC 60168 tus qauv yog ua haujlwm los txhawb nqa cov tsheb thauj mus los thiab cov khoom siv hauv cov chaw nres tsheb. Lawv qhov kev ua tau zoo tseem ceeb yog cantilever (khoov) lub zog ntau dua li lub zog tensile, thiab cov insulators rau qib voltage ntawm 245 kV thiab siab dua yog feem ntau sib sau los ntawm cov khoom sib txuas sib txuas.
Creepage Distance thiab Pollution Performance
Hauv siab -voltage ceramic rwb thaiv tsev cov cuab yeej, qhov kev ncua deb yog qhov tseem ceeb raws li qhov ntsuas hluav taws xob. IEC 60815 tus qauv faib cov qhab nia sib kis ua tsib pawg, los ntawm A (lub teeb heev) txog E (hnyav heev). Qhov yuav tsum tau muaj kev nkag mus deb yog kwv yees li 16 mm / kV nyob rau hauv ib puag ncig huv si, tab sis nce mus rau 31 mm / kV lossis siab dua hauv ntug dej hiav txwv ntsev - tshuaj tsuag thiab chaw ua haujlwm. Rau cov txheej txheem disc insulators, chav nyob deb deb yog kwv yees li 300 hli; rau anti- huab cua (dav-shed) insulators, nws tuaj yeem ncav cuag 400-480 mm; whereas qhib- huab cua aerodynamic disc insulators muaj qhov kev nkag siab loj dua kom ua tiav tus kheej-kev ua haujlwm huv hauv thaj chaw suab puam.
Kev lag luam tawm - tawm tsam cov insulators sib xyaw yog ncaj nraim. Porcelain yog hydrophilic, yog li ib txheej ntub dej ua rau cov khoom siv. Cov khoom siv hluav taws xob ua haujlwm nyob rau hauv IEC Chav Kawm D/E ib puag ncig ib puag ncig hais txog ntev -creepage tiv thaiv- cov kab pos huab ntxiv rau teem sijhawm nyob -kab ntxuav, siv RTV silicone coatings los kho hydrophobicity, los yog hloov mus rau cov khoom siv insulators. Ceramics khaws cov txiaj ntsig zoo hauv thaj chaw seismic, nyob rau hauv qhov raug UV heev, thiab rau cov ntawv thov uas xav tau 40- xyoo- kev pabcuam lub neej uas tsis muaj tshuaj lom neeg.
