Qee Qhov Teeb Meem txog Puas Muaj Kab Ntxig Ruaj

Comulite insulators yuav tsum tau siv ntau dua hauv Suav teb. Nws yog qhov tsim nyog kom tawg los ntawm kev nkag siab tias tib neeg siv cov tshuaj tiv thaiv kev ua qias tuaj kom co lub luag hauj lwm ntawm cov kab lis kev cai plooj (veneers) thiab cov iav insulators. Yuav kom ua tiav lub hom phiaj no, peb yuav tsum mob siab rau cov teeb meem hauv qab no thiab txuas ntxiv ua txoj haujlwm tshawb nrhiav ntau dua.

1. Kev xaiv ntawm lub zog hauv tshuab

Qhov tshwj xeeb tshaj plaws ua tau zoo ntawm pawg insulator ntxhais pas nrig yog qhov siab ua tau thiab siab siab lub zog. Nws lub zog tensile tuaj yeem ncav cuag 7000MPa, thiab lub zog tshwj xeeb yog 5 zaug ntawm cov roj carbon cov pa roj carbon zoo. Qee lub cheeb tsam thiab cov chaw haujlwm tau thov kom siv cov hluavtaws hluavtaws, thiab cov neeg kho tshuab lub zog tau nce los ntawm ib qib piv nrog cov kab lis kev cai thiab cov iav pleev qhov tsis muaj zog, xws li 160kN siv cov kab hluavtaws insulators thiab 210kN siv hluavtaws insulators. Qhov tseeb, thaum lub nra yog tsawg dua 40% ntawm qhov ntsuas cov tshuab ntaus nqi, kev ntseeg tau ntawm lub lag luam tuaj yeem lav tau. Yog li, cov hluavtaws hluavtaws muaj peev xwm xaiv tau raws li tus qauv ntawm cov plooj (veneers) insulators tsis tas yuav tsum nce cov nqi kho tshuab. Lub hauv paus thauj khoom deflection ntsuas qhia pom tias cov ntxig hluav taws xob tiv thaiv tau zoo dabtsi yog khoov tsis kam, muaj peev xwm ua kom txav tau thiab ua haujlwm kev vibration. Thaum siv hauv lub kaum pob ntauwd, nws tuaj yeem tiv taus qee lub sijhawm khoov. Hauv kev ua haujlwm ntev ntawm cov khoom lag luam nrog cov qauv sib txuas txawv ntawm qhov kawg, qhov kev hloov pauv ntawm cov tshuab txhua yam yuav txawv, thiab kev tshawb fawb ntxiv yog xav tau.

2. Xaiv los ntawm qhov deb

Muaj ob lub tswv yim hauv tsev thiab txawv teb chaws ntawm kev xaiv ntawm cov kab hluav taws xob tiv thaiv: ib qho yog xav txog kev tsis zoo ntawm cov khoom ntaws sab saum npoo hydrophobicity, noj 1: 1; qhov thib ob yog los sib sau ua ke kev ua haujlwm tam sim no hauv teb chaws, qhov kev ncua deb tshwj xeeb tuaj yeem txo qis tsim nyog, xws li hluav taws xob hluav taws xob tuaj yeem coj cov pluaj av pleev plooj 2/3 lossis 3/4. Txhawm rau ntsuas cov txheej txheem qhov ntev ntawm cov hluavtaws insulators, JB / T8460 kev lag luam tus qauv thiab lub teb chaws hloov chaw "Coj lus qhia txog kev siv hluavtaws insulators" kev sib koom ua ke: 0-II qib kev ua qias tuaj thaj chaw, qhov sib piv yog 20mm / kv

Hauv thaj tsam III-IV cov pa phem, qhov kev deb txav tshwj xeeb yog 25 hli / kv. Qhov tseeb, qhov kev cai no siab dua qhov xav tau ntawm GB / T16434 rau thaj chaw huv thiab qhov chaw dav dav; rau cov chaw muaj kuab paug hnyav, nws yog 3/4 ntawm cov ntxig hluav taws kub.

3. Kev ntxuav tu qhov teeb meem

Seb hluavtaws insulator sau cov pa phem yuav hnyav dua li cov ntxig hluavtaws, tsis muaj kev pom zoo. Qee qhov kuab paug flash teeb meem thiab kev txuam ntau ntawm cov hluavtaws hluavtaws hauv cov chaw muaj kuab paug hnyav ua rau muaj lus nug txog seb puas yuav tsum tau tu. Vim tias qhov tso pa hluav taws xob siab ntawm qhov muaj cov kab hluav taws xob, txawm hais tias qhov dej rov qab poob qis lossis ploj mus ntev, qhov fouling siab yog 20% siab dua ntawm qhov ntawm cov rwb thaiv tsev. Yog li, chaw tu thiab thaj chaw dav dav tsis muaj kev cheb. Rau qhov tshwj xeeb tshaj yog kev lag luam thiab dej qab ntsev-alkali muaj cov kab mob tsis huv, yuav siv cov kev hloov pauv tsis tu ncua. Txhua qhov chaw tuaj yeem ua raws li koj tus kheej kev paub dhau los, thaum dej hloov kho cov dej hloov ntau thiab cov ntsev muaj peev xwm ntau dua (piv txwv, ntau dua 0.2 mg / cm2), lub tshuab hluav taws xob hloov, thiab siv qhov no los txiav txim lub voj voog hloov.
