Silicone rubber composite insulators tau maj mam hloov cov porcelain thiab iav insulators nyob rau hauv high-voltage fais fab kis systems, vim lawv zoo heev hydrophobicity, anti-pollution kev ua tau zoo thiab lub teeb yuag nta. Cov khoom siv tsim nyog-oriented tsim nteg lub hauv paus rau kev pab cuam ntev ntev.
Nyob rau theem tsim, engineers xub xaiv lub hauv paus silicone roj hmab mis. High-temperature vulcanized silicone roj hmab (HTV-SR) yog dav siv rau insulator sheds. Fillers xws li alumina trihydrate yog ntxiv los txhim kho arc-tiv taus thiab taug qab-ua haujlwm ua haujlwm. Cov ntsiab lus muab tub lim tsawg dhau ua rau muaj qhov yaig nyob rau hauv hluav taws xob arcs, thaum cov khoom siv ntau dhau yuav txo cov neeg kho tshuab hloov pauv thiab muaj peev xwm hloov pauv hydrophobic. Cov tub ntxhais pas nrig hauv lub insulator siv iav fiber reinforced epoxy resin, uas muab lub zog tensile. Lub interface ntawm silicone roj hmab vaj tsev thiab FRP pas nrig yog ib qho tseem ceeb tsim taw tes; tsis zoo interface bonding ua rau sab hauv ib feem tawm thiab delamination tsis ua hauj lwm.
Cov qauv tsim muaj xws li cov duab los, qhov sib txawv ntawm qhov sib txawv thiab qhov deb ntawm qhov nkag. Rau cov cheeb tsam uas muaj kuab paug hnyav, yuav tsum tau teeb tsa qhov kev ncua deb ntawm qhov loj dua. Shed profile yuav tsum tsis txhob muaj dej txuas hauv qab los nag hnyav. Hardware fittings ntawm ob qho kawg yuav tsum tau sib phim crimping qauv kom tsis txhob muaj kev ntxhov siab.
Thaum lub sij hawm tsim, sib tov, vulcanization thiab txhaj tshuaj molding tsis yuav tsum tau nruj me ntsis tswj. Uneven vulcanization ua rau qhov tsis sib xws ntawm qhov chaw ua haujlwm. Cov khoom tiav dhau los ntawm cov kev sim kuaj sim. Cov kev ntsuam xyuas muaj xws li kev faib tawm hydrophobicity, kuaj kev ua qias tuaj, kev ntsuas qhov paug tawm ib nrab, ntsuas qhov ntsuas tensile thiab kuaj kev laus ultraviolet.
Txawm tias muaj kev tsim thiab tsim khoom zoo tshaj plaws, kev raug sab nraum lub sijhawm ntev ua rau muaj kev pheej hmoo: corona aging, deg chalking thiab hydrophobicity poob. Cov neeg tsim qauv yuav tsum sib npaug ntawm cov khoom siv hluav taws xob, lub zog siv hluav taws xob thiab cov cuab yeej tiv thaiv kev laus kom lav qhov kev pab cuam lub neej nyob rau ntau xyoo.
