Raws li kev sib cais ntawm lub tshuab hluav taws xob tseem ceeb, kev ntseeg tau ntawm disconnecting hloov ncaj qha cuam tshuam cov kev cuam tshuam ncaj qha cuam tshuam cov phiaj xwm kev nyab xeeb ncaj qha. Kab lus no siv covGw 4-126 disconnecting hloovUa piv txwv, sib txuasIec {62271-102 tus qauvthiab cov tswv yim engineering kev paub los piav ntau ntxiv ntawm kev ua haujlwm thiab kev saib xyuas.
I. Cov Lus Qhia Txog Kev Kho Txuj Ci Txuj Ci
Kev Hu Xov Tooj
Kev Sib Cais Kev Ntsuas:
Siv micro-ohmermeter (qhov tseeb ± 1%) qis dua 10% ntawm cov ntaus nqi tam sim no. Tus Qauv Qauv:Tsawg dua los yog sib luag rau 200μω (126kV chav kawm)Cov. Yog tias tiv taus ntau tshaj qhov txwv:
Oxidation Txheej Kev Kho Mob: For thickness >{{0 {0}}. 2 hli, Polish raws kev sib cuag kev coj ua120-} grit sandpaper(Zam tsis txhob txhuam hlau los tiv thaiv cov khoom siv ua haujlwm).
Kev thov roj: ThovMolyKote® g -5011(Nyiaj-muaj), tuab 0. {3}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}
Hnav Tshuaj Saib Xyuas: Siv laser tuab ntsuas cua txhua 6 lub hlis. Tso Quav:Tsawg dua los yog sib npaug rau 3 hli(raws li teev nyob rau hauvDl / t 596).
Kev tswj hwm kev ua tau zoo
Plooj (veneers Insulator Tu:
Rau cov cheeb tsam nrog Chav Polleded III lossis siab dua, ua rau peb lub hlis twg ntxhua khaub ncaws (siab{{{{0}}}. 4-0.6mpa, water temperature >5 DEGREE) kom tswj tau ntsev ntom tsawg dua lossis sib npaug rau 0. 1mg / cm².
Yuav kom paub tawg: Use an ultrasonic flaw detector. Replace if crack depth >0.5mm or length >30 hli (GB 8287.1).
Kev Tshuaj Ntsuam Xyuas Insulator: Hydrophobicity xeem yuav tsum ncav cuagQib HC1 (spray method). Replace if silicone rubber sheds are damaged (>5cm²).
Kev ua haujlwm ua haujlwm optimization
Kev khiav hauj lwm Torque tswj:
Calibrate siv cov ciaj ntswj digital. Qhib / kaw lub zog tsawg dua los yog sib npaug rau 250n · M (GW4 series).
Lubrication kev tswj:
Tig Ncej: Ntub biannually (caij nplooj ntoos hlav / caij nplooj zeeg) nrogMolybdenum disulfide lithium-raws li cov roj (nlgi qib 2). Sau 60% ntawm cov kabmob sib txuas.
Gearbox Roj Hloov: HloovCLP 220 roj every 5 years. Replace earlier if kinematic viscosity change >15%.
Ii. Txheej Txheem Txheej Txheem Installation
Foundation Proverming Yuav Tsum
Leveling tswj: Calibrate nrog qib laser (ntev / tom qab yuam kev<2°). For multi-section series, use a theodolite to ensure coaxial deviation <1°.
THAUJ TOG RAU NKOJ TROLT KHO: M24 ntsia liaj qhov rooj preload quab yuam300N·m±5%Cov. Ua ntaub ntawvZINGA® anti-corrosion txheej(tuab ntau dua lossis sib npaug rau 80μm) post-installation.
Kev Tsim Kho Cov Khoom Siv Hauv Paus
Cov Neeg Xaiv Xaiv: SivTmy -50 × 6 tooj liab busbars(hla ntu ntau dua los yog sib npaug rau 50mm²) nrog tinned 搭接 cov chaw.
Hauv av tiv thaiv kev sim: Measure via four-pole method. For soil resistivity >100, thov cov neeg sawv cev tsis kam tiv thaiv (piv txwv li, bentonite) kom ntseeg tau<4Ω.
Kev hloov kho ib puag ncig ib puag ncig
Thaj chaw ntug hiav txwv:
Kev siv316L stainless hlauCheebtsam (ntsev tshuaj tsuag mus kuaj ntau dua lossis sib npaug rau 2000 teev).
RTV-II anti-wretion Grashover Txheej({{{{0}}}. 3-0.5mm thickness).
Cheeb tsam txias:
Siv cov roj tsawg-kub (ncuav taw qhia -40 degree).
Txhim kho hluav taws xob cua sov (200W) ntawm kev ua haujlwm.
III. Kev Tiv Thaiv Kev Nyab Xeeb Kev Kho Mob
Saib Xyuas Cov Tshuab:
Muab ciaWireless Kub Sensors(± 1 qhov tseeb raug) rau kev sib tham txog lub sijhawm tiag tiag.
Kev sivKev co sensors to detect mechanical looseness (alarm at >200zz).
Cov Ntaub Ntawv Tswj:
Muaj cov cuab yeej siv keeb kwm daim npav teev cia cov khoom siv hluav taws xob tsim txiaj, lub sijhawm lubrication, thiab lwm yam.
Siv QR Code BITINGING rau cov chaw seem seem kev taug qab.
Nqi Muaj txiaj ntsig: Kev txij nkawm nthuav dav lub neej ntawm 20 txog 30 xyoo, txo lub neej nyob ntawm 40%.
