Thooj insulatorsyog qhov tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub. Cov ntu hauv qab no los saib xyuas cov hauv paus cag ua rau lawv ua tsis tiav thiab nthuav qhia cov tswv yim.
Kev tuav tsis ncaj ncees
1. NEEG KHO TSHUAB
· Cov Qws Lod Kev Npoo:Kev khoov rau ntawm cov fiberglass - eceas txhawb epoxy tseem ceeb tshaj plaws epoxy tseem ua rau muaj cov microcracks tuaj yeem ua rau muaj kev ntseeg siab.
· Raug puas tsuaj:Saj zawg zog silicone roj hmab los yog qhov tsis muaj zog rau kev txiav lossis kua muag thaum raug cov cuab yeej ntse lossis cov khoom siv abrasive thaum tuav.
2. Sealing tsis ua haujlwm
· Kev sib khi tsis zoo ntawm qhov kawg fittings lossis cov kab nrib pleb hauv cov pob zeb silicone tsoos acidic paug (piv txwv li cov kua ntses acid, cov pa phem hloov) mus rau kev nkag.
· Lub tsho ntev acid raug rau cov pas nrig tseem ceeb, muaj feem cuam tshuam ua kev puas tsuaj loj thiab cov neeg ua neeg ua yeeb yam poob.
3. Cov xwm txheej raug
· Nyem:Tsis muaj kev nyab xeeb thaum muaj kev cuam tshuam rau kev cuam tshuam kev puas tsuaj.
· :Kev ntxhib tuav (cab, hatmering) lossis cov cuab yeej tsis raug cai ua rau muaj kev ntxhov siab hauv cov kev ntxhov siab hauv ib cheeb tsam.
Sab nraud yuam kev
· Los / tsev puas tsuaj: Kev tsim kho kev tsim kho, noog pecking (magpies / crows), tsiaj zom (cov hlua), lossis cov hlua - Kite (Kite Strings / Ceg).
· Cov Qws Lod Kev Npoo:Huab Cua (Galres / Cov Cua daj
Kev tiv thaiv kev ntsuas:
· Yuav tsum muaj cov noog tshwj xeeb cuam tshuam nyob ze cov av ntub / cov neeg ua liaj ua teb.
· Yuav tsum tau muaj cov nroj tsuag tswj hauv hav zoov kom tiv thaiv kev cuam tshuam rau tsob ntoo tsaws tsag.
Kev Tsim Kho Raug
· Tsis tshua muaj neeg kho tshuab lub zog:Tsis muaj tseeb lub thawv fiber ntau lossis kev kho tsis txaus thaum lub sijhawm tsim khoom.
· Interface tawg & britle bacacture:Voids hauv cov tseem ceeb -}}}} xaus haum kev sib txuas lossis microcracks propagating sijhawm.
· Silicone roj hmab ib txwm:Tsis muaj zog UV stabiilizers / anti - oxidants coj mus rau cov chalking npoo / tawg.
Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob
1. Xob laim flashover
· Ua puas tus qauv:Arc ntau dua carbonicizing sheds thiab hlawv grading rings.
· - qhov chaw pheej hmoo:Xob laim - ib qho ntawm cov aav nrog tsis muaj zog ntauwd.
2. Los nag
· Cov kev mob los ntawm:Qhuas cov khoom noj muaj kuab paug los ntawm qis - Tsis taus nag (acid los nag).
· Tsis muaj zog:Insulators tsim los cov chaw huv tsis muaj kev qias neeg muaj kuab paug.
3. Muaj kuab Zis
· Kev Siv / Caud Kev Phem Txom Nyem
· Yoov (pos huab / npau taws) yaj cov kuab paug rau hauv cov yeeb yaj kiab ua yeeb yaj kiab.
Silicone kom zoo dua:Hydrophobicity qeeb tab sis tsis tshem tawm, txoj kev pheej hmoo hauv qab cov kev paug hnyav.
4. Noog Speamer Flashover
· Physics:Noog excrement cov hniav txuas hniav tau los, tsim kom muaj kev sib tw ua ke.
· -} kev pheej hmoo tsiaj:Cov noog loj (eagles / storks) lossis cov noog yaj (Crocking).
Qhov taw qhia tseem ceeb ntawm kev sib xyaw ua ke insulator
Decradation Drivers:
· Ib puag ncig:Ultraviolet (UV) -}}}} Kev Tawm Tsam Polymer Puas, Thermal Cycling Cracks, Vaum {}} pab corrosion.
· Hluav taws xob:Ib nrab rho tawm (corona / arcing) eroding ua kom ntub dej.
Cov tsos mob laus:
· Hardened, tawg ua kom cov ntoo uas muaj cov elasticity txo qis
· Poob phaus thiab qhov tsis zoo hloov hauv cov pas nrig tseem ceeb
Qhov ntxiv kev pheej hmoo rau cov neeg insulator laus
Tsim / Xaiv Yuam Kev:
· Cov tsis muaj peev xwm deb deb rau cov chaw qias neeg
· Kev ntxhov siab -}}}} -}} fitting tsim
Txij Nkawm Cov Ntxhw:
· Tsis txaus ntseeg tu
· Cov cuab yeej kuaj mob hauv qab (IROFFRY / UV kev ntsuas)
