Dab tsi yog Lifespan ntawm Composite Insulators?

Tus txheej txheem lifespan ntawm composite insulators feem ntau yog 15-30 xyoo, nrog rau cov lifespan tshwj xeeb cuam tshuam los ntawm yam xws li cov ntaub ntawv, ib puag ncig, thiab voltage theem. Composite insulators muaj silicone roj hmab sheds thiab iav fiber reinforced epoxy resin core pas nrig. Lawv lifespan feem ntau yog nyob ntawm qhov kev laus ntawm cov roj hmab silicone thiab qhov tuav tus nqi ntawm cov tub ntxhais qws lub zog txhua yam. Nyob rau hauv cov xwm txheej zoo (xws li qhov chaw qhuav, huv si), lub neej ntev tuaj yeem ncav cuag 30 xyoo; Txawm li cas los xij, nyob rau hauv ib puag ncig uas muaj kuab paug hnyav, muaj zog ultraviolet hluav taws xob, los yog cov neeg kho tshuab siab, lub neej ntev yuav luv dua li 15 xyoos.

Kev lag luam cov qauv, IEC 61109 thiab GB / T 19519 qhia txog cov kev ua haujlwm thiab cov qauv kev sim rau cov khoom siv hluav taws xob sib xyaw, suav nrog kev ntsuas kev laus sai (xws li kev ntsuas ntsev tsuag thiab kev kuaj kev laus ultraviolet) thiab kev ntsuas cov khoom siv. Hauv kev siv cov tswv yim, nws raug nquahu kom tsis tu ncua xyuas cov insulator qhov chaw hydrophobicity, los ua kev puas tsuaj, thiab seb lub pas nrig tseem raug puas; cov no yog cov cim tseem ceeb rau kev txiav txim siab nws txoj sia nyob.

Kev ntsuas kom ncua lub neej muaj xws li: xaiv cov khoom siv roj hmab silicone uas muaj zog tiv thaiv huab cua, tu cov pa paug tsis tu ncua (xws li siv cov dej yaug hluav taws xob), thiab zam kev cuam tshuam rau kev siv tshuab. Nyob rau hauv ntug dej hiav txwv los yog industrially polluted cheeb tsam, lub sij hawm soj ntsuam yuav tsum tau luv luv rau 1-2 zaug ib xyoos. Yog tias qhov tawv nqaij tawv, tawg, lossis cov hauv paus poob qis hauv daim tiab, daim tiab yuav tsum tau hloov tam sim ntawd.
