Composite insulators thiab iav insulators yog ob hom insulators uas ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm hluav taws xob. Muaj ntau yam kev txiav txim siab los coj mus rau hauv tus account thaum xaiv ntawm ob hom, nrog rau yam xws li tus nqi, durability, thiab kev ua tau zoo txhua yam muaj kev cuam tshuam rau kev txiav txim siab.
Composite insulators yog tsim los ntawm ob lub ntsiab lus: fiberglass core thiab polymer matrix. Lub fiberglass tub ntxhais yog lub luag hauj lwm rau muab lub zog thiab rigidity ntawm lub insulator, thaum lub polymer matrix yog lub luag hauj lwm los tiv thaiv lub fiberglass los ntawm lub ntsiab. Lub polymer feem ntau yog tsim los ntawm silicone lossis ethylene propylene diene monomer (EPDM).
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov khoom siv hluav taws xob sib xyaw yog tias lawv muaj peev xwm tiv taus ib puag ncig degradation. Lawv tau tsim los tiv thaiv qhov kub thiab txias, UV hluav taws xob, thiab lwm yam ib puag ncig uas tuaj yeem ua rau muaj kev puas tsuaj rau cov insulators. Qhov no ua rau lawv zoo tagnrho rau siv rau thaj chaw uas muaj huab cua hnyav, xws li suab puam, ntug hiav txwv dej, thiab qhov chaw siab.
Lwm qhov zoo dua ntawm cov insulators sib xyaw yog lawv lub zog txhua yam. Cov tub ntxhais fiberglass muab kev txhawb nqa zoo heev, ua cov khoom sib xyaw ua ke zoo heev rau cov neeg kho tshuab kev ntxhov siab. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj cua kub thiab kev co, qhov twg cov insulators feem ntau yuav raug rau cov neeg kho tshuab tseem ceeb.
Composite insulators kuj tseem tiv taus tshuaj corrosion. Lawv tsis raug cuam tshuam los ntawm kev raug tshuaj lom neeg, ua rau lawv zoo tagnrho rau kev siv nyob rau hauv cov cheeb tsam uas muaj cov pa phem ntau lossis muaj kev sib kis.
Ib qho ntawm qhov zoo tshaj plaws ntawm cov khoom siv insulators yog lawv lub teeb yuag. Muab piv rau cov iav insulators, cov khoom siv hluav taws xob sib xyaw yog qhov sib dua, ua rau lawv yooj yim dua los tuav thiab nruab. Qhov no tuaj yeem yog qhov tseem ceeb tshwj xeeb hauv cov cheeb tsam uas muaj qhov nyuaj los yog muaj kev nkag tau yooj yim, qhov hnyav insulators tuaj yeem nyuaj rau kev thauj mus los thiab nruab.
Composite insulators yog qhov kev xaiv zoo tshaj plaws rau kev siv ntau yam kev siv, los ntawm cov kab hluav taws xob sib kis mus rau cov tshuab hluav taws xob tsawg. Lawv yog cov ruaj khov, txhim khu kev qha, thiab tus nqi tsim nyog, ua rau lawv muaj kev xaiv nrov rau cov kws tsim hluav taws xob thiab cov chaw muab hluav taws xob thoob ntiaj teb.
Cov iav insulators tau nyob ib puag ncig txij li hnub thaum ntxov ntawm kev lag luam hluav taws xob thiab yog ib qho kev xaiv rau cov kab hluav taws xob siab hluav taws xob. Lawv yog ua los ntawm iav, uas yog ib qho zoo heev hluav taws xob insulator thiab muab zoo heev tiv thaiv hluav taws xob conductivity.
Ib qho ntawm qhov zoo ntawm cov iav insulators yog lawv qhov siab tiv thaiv hluav taws xob. Lawv tau tsim los muab kev tiv thaiv zoo ntawm tus neeg xyuas pib thiab ib puag ncig ib puag ncig, tiv thaiv hluav taws xob tawm thiab ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov tshuab hluav taws xob.
Lwm qhov zoo ntawm cov iav insulators yog lawv cov kev ua tau zoo heev nyob rau hauv high voltage tej yam kev mob. Lawv tau tsim los tiv thaiv kev kub ntxhov ntawm hluav taws xob, ua rau lawv zoo tagnrho rau kev siv hauv cov kab hluav taws xob siab. Cov iav insulators tseem tuaj yeem muab kev tiv thaiv xob laim zoo dua piv rau cov khoom siv hluav taws xob sib xyaw.
Cov iav insulators kuj muaj qhov zoo thermal stability, uas ua rau lawv zoo tagnrho rau siv nyob rau hauv cov cheeb tsam nrog huab cua kub hloov. Lawv tsis cuam tshuam los ntawm kev hloov pauv ntawm qhov kub thiab txias, tso cai rau lawv tswj hwm lawv cov rwb thaiv tsev ntawm ntau qhov kub thiab txias.
Txawm li cas los xij, thaum iav insulators muaj qee qhov zoo, lawv tsis yog tsis muaj lawv qhov tsis zoo. Ib qho ntawm qhov tsis zoo ntawm cov iav insulators yog lawv cov fragility. Cov iav insulators muaj qhov cuam tshuam rau kev puas tsuaj ntawm lub cev thiab muaj kev pheej hmoo ntawm kev tawg lossis tawg yog tias raug huab cua huab cua.
Cov iav insulators kuj hnyav, ua rau lawv nyuaj rau kev thauj thiab nruab. Qhov no tuaj yeem yog qhov teeb meem tseem ceeb hauv cov cheeb tsam uas muaj qhov nyuaj los yog kev nkag tau yooj yim, qhov hnyav insulators tuaj yeem nyuaj rau kev thauj thiab nruab.
