Khoom txhais
Iav insulators ib qho insulator ua los ntawm tempered iav.Nws nto yog nyob rau hauv lub xeev ntawm compression prestress, xws li tawg thiab hluav taws xob tawg, iav insulator yuav tawg mus rau hauv me me pieces, feem ntau hu ua "tus kheej tawg".Qhov no feature tshem tawm qhov yuav tsum tau rau "zero value" nrhiav kom tau iav insulators thaum lub sij hawm ua hauj lwm.
Lub iav insulator yog crystallization ntawm kev sib xyaw ntawm iav thiab insulator.Vim yog cov yam ntxwv ntawm iav piv nrog cov hluav taws xob porcelain, iav insulators muaj kev ruaj ntseg zoo dua hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab lawv cov pob tshab ua rau nws yooj yim los xyuas qhov kev puas tsuaj thaum lub sijhawm ua haujlwm, yog li cov kev ntsuas hluav taws xob tsis tu ncua rau cov insulators raug tshem tawm.Lub zog hluav taws xob ntawm iav feem ntau tseem zoo ib yam thoob plaws hauv nws txoj haujlwm, thiab nws cov txheej txheem kev laus qeeb qeeb dua li cov plooj (porcelain).Yog li ntawd, cov iav insulators feem ntau raug tso tseg vim kev puas tsuaj rau tus kheej, uas tshwm sim hauv thawj xyoo ntawm kev ua haujlwm, qhov tsis xws ntawm cov plooj (porcelain insulators) pib pom tsuas yog tom qab ob peb xyoos ntawm kev ua haujlwm.
Cov txheej txheem no qhia txog cov kev cai dav dav, cov qauv kev xaiv, kev soj ntsuam xyuas, kev lees paub, ntim thiab kev thauj mus los, kev teeb tsa thiab kev tswj xyuas kev ua haujlwm, thiab kev ntsuas kev ua haujlwm rau ac overhead kab insulators nrog nominal voltages saum 1000V.
Cov qauv no muaj feem xyuam rau disk-type suspended porcelain thiab iav insulators (insulators luv luv) siv nyob rau hauv ac overhead hwj chim kab, fais fab nroj tsuag thiab substations nrog nominal voltage siab tshaj 1000Y thiab zaus 50Hz.Qhov siab ntawm qhov chaw teeb tsa yuav tsum qis dua 1000m, thiab qhov kub ntawm qhov chaw yuav tsum nyob ntawm -40 ° C txog +40 ° C.2 Cov ntaub ntawv siv tau zoo
