Iav insulator muaj cov khoom siv zoo heev thiab hluav taws xob, nws lub zog tensile, hluav taws xob tawg tsis kam, kev co qaug zog tsis kam, arc hlawv tsis kam thiab thermal shock kuj zoo dua li cov plooj (porcelain insulator), ceramic insulator nws muaj kev ua haujlwm zoo rwb thaiv tsev, huab cua hloov tsis kam, kub tsis kam thiab sib dhos rhiab qhov zoo, yog dav siv nyob rau hauv ntau theem voltage ntawm kab.
Insulator kev pab cuam lub neej teeb meem
Lub iav insulator muaj cov yam ntxwv ntawm xoom nws tus kheej tawg. Yog vim li cas rau tus kheej tawg yog cov impurities thiab nodules nyob rau hauv lub khob thaum lub sij hawm tsim khoom. Yog hais tias cov impurities thiab nodules dispersed nyob rau hauv lub puab nro txheej, lub zos nws tus kheej tawg yuav tshwm sim nyob rau hauv ib lub sij hawm ntawm lub sij hawm tom qab cov khoom tsim. Yog li ntawd, lub tsev tsim khoom yuav tsum khaws cov khoom rau ib lub sijhawm tom qab kev tsim khoom txhawm rau txhawm rau txhawm rau nrhiav qhov zoo ntawm qhov tsis zoo hauv kev tsim khoom.
Yog hais tias impurities los yog nodules dispersed nyob rau hauv txheej compact txheej, tom qab khiav ntawm lub hwj chim kab rau ib lub sij hawm ntawm lub sij hawm, nyob rau hauv qhov kev txiav txim ntawm txias txias thiab kub kub txawv thiab mechanical thiab hluav taws xob load, nws muaj peev xwm ua rau lub iav rwb thaiv tsev rau nws tus kheej. - tawg. Tsis tas li ntawd, thaum lub iav insulator ntub dej ntawm qhov chaw, nws yuav tso tawm ib nrab ntawm qhov kev txiav txim ntawm lub zog zaus voltage. Cov cua sov mus ntev los ntawm kev tso tawm ib nrab yuav ua rau cov iav rwb thaiv tsev poob thiab ua rau tus nqi xoom nws tus kheej tawg. Yog li ntawd, tus kheej-detonation tus nqi ntawm iav insulators ua hauj lwm nyob rau hauv qhov chaw qias neeg yuav raug nce.
Txawm li cas los xij, tus kheej-detonation tus nqi ntawm iav insulators txawv ntawm qhov deterioration tus nqi ntawm cov plooj (porcelain insulators) thiab cov laus tus nqi ntawm cov organic composite insulators. Tus kheej-detonation tus nqi ntawm iav insulators belongs rau thaum ntxov raug, thiab nrog rau ncua sij hawm ua hauj lwm, tus kheej-detonation tus nqi yuav poob ib xyoos ib zaug, thaum lub deterioration tus nqi ntawm porcelain insulators belongs rau lig raug. Nrog rau ncua sij hawm, nyob rau hauv qhov kev txiav txim ntawm electromechanical ua ke load, tus deterioration tus nqi yuav maj mam nce. Nws yog feem ntau ntseeg tias lub neej kev laus ntawm iav insulators thiab porcelain insulators yog txog 50 xyoo. Lub neej kev laus ntawm cov khoom siv insulators tsis tshaj 25 xyoo.
