Khoom txhais
Composite insulator yog ib lub siab voltage insulator ua los ntawm cov organic silicone roj hmab cov khoom siv.Cov khoom tseem ceeb yog bar hom thiab cross caj npab hom, uas yuav siv tau raws li overhang thiab tensile bearing rwb thaiv tsev ntawm 35kV, 110kV thiab 220kV kab.Tam sim no tseem muaj cov khoom siv insulator rau 10kV kab.
Cov qauv ntawm cov khoom siv hluav taws xob zoo ib yam li cov khoom siv hluav taws xob, uas yog tsim los ntawm qhov kawg fittings, rwb thaiv tsev umbrell-shaped corrugate, sheath thiab ib lub tes tsho.
Yam khoom
Composite insulators tuaj yeem muab faib ua: kab sib xyaw insulators thiab chaw nres tsheb fais fab, hluav taws xob sib xyaw insulators.Nws kuj tseem tuaj yeem muab faib ua cov pas nrig ncua kev sib txuas insulators, rab koob sib xyaw insulators, hla caj npab sib xyaw insulators, pillar composite insulators, windbreak composite insulators thiab lwm yam.
Qhov zoo
Nws muaj qhov zoo hauv qab no:
(1) Cov khoom siv zoo tshaj plaws: raws li lub plawv pas nrig yog ua los ntawm epoxy iav fiber ntau, nws lub zog nthuav dav yog 1.5 npaug ntawm cov hlau zoo tib yam thiab 3 ~ 4 npaug ntawm lub zog siab porcelain, nws axial tensile quab yuam tshwj xeeb, thiab nws muaj zog vibration absorption muaj peev xwm, thiab nws cov seismic damping kev ua tau zoo heev, 1/7 ~ 1/10 ntawm cov porcelain insulator.
(2) Cov hlua hluav taws xob sib xyaw muaj qhov ua tau zoo los tiv thaiv kev ua qias tuaj: cov insulator puas muaj hydrophobicity.Thaum nws los nag, lub kaus-zoo li tus corrugated nto ntawm cov khoom siv insulator yuav tsis ntub thiab tsim cov yeeb yaj kiab dej.Hloov chaw, nws poob zoo li cov hlaws dej thiab tsis yooj yim los tsim cov channel conductive.
(3) Kev tiv thaiv corrosion zoo heev: qhov dej ntws tawm ntawm qhov chaw thiab flashover ntawm cov ntaub ntawv insulator irreversible deterioration thiab kab tshwm sim.Tus qauv dav dav tsis qis dua qib 4.5 (uas yog, 4.5kV), thiab cov khoom siv hluav taws xob sib xyaw yog qib 6 ~ 7.
