Txheej txheem cej luam
10kV ~ 110kV composite post insulators rau cov chaw nres tsheb fais fab yog siv rau cov khoom siv hluav taws xob thiab cov khoom siv ua haujlwm hauv 10kV ~ 110kV AC systems, tshwj xeeb tshaj yog nyob rau thaj chaw muaj kuab paug.Nws tuaj yeem tiv thaiv cov pa phem flashover xwm txheej thiab txo cov haujlwm ua haujlwm thaum lub sijhawm ua haujlwm.Nws yog ib tiam tshiab ntawm cov khoom insulator nrog kev ua tau zoo heev.
Nta
1. Kev ua tau zoo ntawm hluav taws xob thiab kev ua haujlwm siab.Lub zog tensile thiab flexural ntawm epoxy fiberglass daim duab rods nqa sab hauv yog ob zaug ntawm cov hlau zoo tib yam thiab 8-10 npaug ntawm cov ntaub ntawv muaj zog porcelain, uas zoo txhim kho kev ntseeg tau ntawm kev ua haujlwm nyab xeeb.
2. Cov khoom zoo los tiv thaiv kev ua qias tuaj thiab muaj zog tiv thaiv kev ua qias tuaj flashover.Nws ntub dej tiv taus qhov hluav taws xob thiab qhov hluav taws xob muaj kuab paug yog 2-2.5 npaug ntawm cov plooj (porcelain insulators) nrog tib qhov nkag mus deb, tsis tas yuav tsum ntxuav, thiab nws tuaj yeem ua haujlwm nyab xeeb hauv thaj chaw muaj kuab paug hnyav.
3. Qhov loj me, lub teeb yuag (tsuas yog 1/6-1/19 ntawm tib theem voltage porcelain insulator), lub teeb qauv, yooj yim thauj thiab nruab.
4. Lub tsev cog khoom silicone roj hmab muaj cov dej zoo tiv thaiv kev ua haujlwm, thiab nws cov qauv tag nrho ua kom cov rwb thaiv tsev sab hauv yog damp, thiab tsis tas yuav muaj kev tiv thaiv kev tiv thaiv kev tiv thaiv kev soj ntsuam los yog ntxuav, uas txo cov haujlwm ntawm kev tu txhua hnub.
5. Zoo sealing kev ua tau zoo thiab muaj zog tiv thaiv hluav taws xob corrosion.Kev tiv thaiv tawm thiab kev taug qab ntawm cov khoom siv tuaj yeem ncav cuag TMA4.5 qib.Nws muaj qhov zoo ntawm kev laus, corrosion kuj thiab kub tsis kam.Nws tuaj yeem siv rau hauv thaj tsam ntawm -40 ℃ ~ + 50 ℃.
6. Muaj zog tiv thaiv thiab poob siab tsis kam, zoo brittleness thiab creep tsis kam, tsis yooj yim rau tawg, khoov tsis kam, siab torsional zog, tuaj yeem tiv taus lub zog sab hauv, muaj zog tawg-pov thawj, thiab tuaj yeem siv sib hloov nrog cov plooj (porcelain) thiab iav insulators.
