Composite insulatorsyog cov khoom tseem ceeb hauv cov tshuab hluav taws xob niaj hnub no. Cov ntu hauv qab no tshuaj xyuas lub hauv paus ua rau lawv ua tsis tiav thiab tam sim no cov tswv yim tiv thaiv.
Kev tuav tsis raug
1. Mechanical puas
· Core Rod Fractures:Kev khoov ntau dhau ntawm cov fiberglass- txhawb nqa epoxy core pas nrig dhau ntawm nws qhov kev ua siab ntev tuaj yeem ua rau muaj microcracks, ua rau muaj kev cuam tshuam zoo rau txhua yam.
· Shed Damage:Saj zawg zog silicone roj hmab sheds yog yooj yim rau kev txiav los yog kua muag thaum raug cov cuab yeej ntse los yog abrasive nto thaum tuav.
2. Sealing Failure
· Tsis zoo sealing ntawm qhov kawg fittings los yog tawg nyob rau hauv silicone vaj tse tso cai rau acidic contaminants (xws li, kua qaub nag, muaj kuab paug) nkag mus rau hauv.
· Lub sij hawm ntev acid exposure embritttles cov tub ntxhais pas nrig, muaj peev xwm ua rau muaj kev puas tsuaj puas tsuaj thiab cov neeg xyuas pib poob.
3. Tej yam xwm txheej
· Kev thauj mus los:Kev ruaj ntseg tsis txaus thaum caij tsheb thauj mus los ua rau muaj kev puas tsuaj.
· Kev teeb tsa:Kev tuav tsis zoo (txuas, hammering) lossis siv cov cuab yeej tsis raug ua rau muaj kev ntxhov siab hauv cheeb tsam.
Kev puas tsuaj sab nraud
· Lub tsev / tsev puas: Kev tsim kev cuam tshuam, noog pecking (magpies / crows), tsiaj zom (squirrels), los yog entanglement (kite hlua / ceg).
· Core qws fractures:Huab cua huab cua (gales / dej nag cua daj cua dub) tsim kom muaj kev sib tw ntau dhau los yog kev ua phem rau tib neeg (dhau phom / pov khoom).
Kev tiv thaiv:
· Yuav tsum tau tshwj xeeb noog deterrents ze wetlands/farmland towers.
· Yuav tsum muaj kev tswj cov nroj tsuag hauv thaj chaw hav zoov kom tiv thaiv kev cuam tshuam ntawm tsob ntoo.
Manufacturing Defects
· Tsis txaus mechanical zog:Cov iav fiber ntau tsis tsim nyog lossis tsis txaus kho thaum lub sijhawm tsim khoom.
· Interface breakdown & brittle fracture:Tsis muaj nyob rau hauv cov tub ntxhais pas nrig- xaus kev sib txuas los yog microcracks nthuav tawm raws sijhawm.
· Silicone roj hmab degradation:Tsis txaus UV stabilizers/anti{0}}oxidants ua rau nto chalking/cracking.
Hluav taws xob Flashover Fault
1. xob laim
· Kev puas tsuaj qauv:Arc taug qab carbonizing sheds thiab hlawv cov qhab nia.
· Siab - thaj chaw muaj kev pheej hmoo:xob laim- tej thaj chaw uas muaj ntau lub hauv av tsis txaus.
2. Los nag Flashover
· Cov xwm txheej tshwm sim:Cov khaubncaws sab nraud povtseg ua kom muaj kuab paug los ntawm qis- tiv thaiv nag (acid nag).
· Vulnerability:Insulators tsim los rau thaj chaw huv si tsis nyob hauv qhov chaw muaj kuab paug.
3. Pollution Flashover
· Kev lag luam / ntsev sib xyaw ua ke
· Moisture (fog / drizzle) dissolves kuab paug rau hauv cov yeeb yaj kiab conductive.
Qhov zoo ntawm Silicone:Hydrophobicity qeeb tab sis tsis tshem tawm, qhov kev pheej hmoo ntawm kev sib kis hnyav.
4. Noog Streamer Flashover
· Physics:Noog excrement txuas hniav sheds, tsim parallel conduction paths.
· Siab - hom kev pheej hmoo:Cov noog loj (eagles / storks) los yog flocking noog (crows).
Key Indicators of Composite Insulator Aging
Degradation tsav tsheb:
· Ib puag ncig:ultraviolet (UV) -induced polymer tawg, thermal cycling tawg, av noo- pab corrosion.
· Hluav taws xob:Ib nrab tso tawm (corona / arcing) eroding shed nto.
Cov tsos mob laus:
· Hardened, tawg los nrog txo elasticity
· Kev poob phaus thiab kev hloov ceev ntawm cov core rods
Ntxiv Risk Factors rau Composite Insulator Aging
Tsim / xaiv yuam kev:
· Tsis txaus creepage nrug rau tej thaj chaw muaj kuab paug
· Kev ntxhov siab- tsom qhov kawg- tsim kom haum
Maintenance Gaps:
· Kev tu lub voj voog tsis txaus
· Cov cuab yeej kuaj tsis tau siv (IR thermography / UV imaging)
