HOM COV Rwb Thaiv Kub

1. Cov khoom siv rwb thaiv tsev

Nws yog siv dav hauv kev rwb thaiv tsev thiab kho cov kab hluav taws xob siab thiab cov busbars mos hauv kev tsim hluav taws xob thiab cov chaw hloov pauv. Ntawm cov insulators ncua, nws tuaj yeem muab faib ua disc suspension insulators thiab rod suspension insulators. Disk suspension insulators yog cov insulators siv dav tshaj plaws rau cov kab kis. Cov insulators ncua zoo li tus pas tau siv dav hauv lub teb chaws Yelemees thiab lwm lub tebchaws.

2. Lub tshuab rwb thaiv tsev ncej

Feem ntau siv rau kev rwb thaiv tsev thiab kev kho tshuab ntawm cov busbars thiab cov khoom siv hluav taws xob hauv cov chaw tsim hluav taws xob thiab cov chaw hloov pauv. Tsis tas li ntawd, cov insulators post feem ntau siv ua ib feem ntawm cov khoom siv hluav taws xob xws li cov disconnectors thiab circuit breakers.

Ntawm cov insulators ncej, nws tuaj yeem muab faib ua cov insulators ncej hom pin thiab cov insulators ncej hom pas nrig. Cov insulators ncej hom pin feem ntau yog siv rau cov kab faib hluav taws xob qis thiab cov kab sib txuas lus, thiab cov insulators ncej zoo li pas nrig feem ntau yog siv rau hauv cov chaw hloov hluav taws xob siab.

3. Cov khoom siv rwb thaiv tsev porcelain

Cov insulators yog cov insulators ua los ntawm cov khoom siv hluav taws xob ceramics. Cov khoom siv hluav taws xob ceramics yog ci los ntawm quartz, feldspar thiab av nplaum. Qhov saum npoo ntawm daim porcelain ntawm cov porcelain insulator feem ntau yog them nrog enamel los txhim kho nws lub zog kho tshuab, tiv thaiv dej thiab nkag mus, thiab ua kom qhov chaw du. Ntawm txhua hom insulators, porcelain insulators yog cov feem ntau siv.

4. Cov khoom siv rwb thaiv tsev iav

Cov Khoom Siv Hluav Taws Xob Cov khoom siv hluav taws xob ua los ntawm cov iav tempered. Nws qhov chaw nyob rau hauv lub xeev ntawm compressive prestress, xws li tawg thiab hluav taws xob tawg, lub iav insulator yuav tawg ua tej daim me me los ntawm nws tus kheej, feem ntau hu ua "self-explosion". Qhov feature no tshem tawm qhov xav tau "zero value" nrhiav tau ntawm cov iav insulators thaum lub sijhawm ua haujlwm.

5. Cov khoom siv rwb thaiv tsev sib xyaw

Kuj hu ua cov khoom siv rwb thaiv tsev. Cov khoom rwb thaiv tsev yog cov khoom rwb thaiv tsev uas muaj cov iav fiber resin core pas nrig, cov khoom siv organic sheath thiab lub kaus mom. Nws yog tus cwj pwm los ntawm qhov me me, lub teeb yuag, lub zog tensile siab thiab kev ua tau zoo heev tiv thaiv kev ua kom tsis txhob lo rau flashover. Txawm li cas los xij, lub peev xwm tiv thaiv kev laus tsis zoo li cov khoom siv rwb thaiv tsev porcelain thiab iav.

Cov insulators sib xyaw muaj xws li: cov insulators zoo li tus pas nrig, cov caj npab insulating, cov insulators post thiab cov insulators hollow. Cov bushings sib xyaw tuaj yeem hloov cov porcelain bushings siv rau hauv ntau yam khoom siv hluav taws xob, xws li transformers, arresters, circuit breakers, capacitive bushings thiab cable terminals. Piv nrog rau lub tes tsho porcelain, nws tsis tsuas yog muaj qhov zoo ntawm lub zog siab, lub teeb yuag thiab me me, tab sis kuj tuaj yeem zam kev puas tsuaj los ntawm kev tawg.

6. Cov insulators uas muaj hluav taws xob tsawg thiab cov insulators uas muaj hluav taws xob ntau

Cov insulators uas muaj hluav taws xob tsawg yog cov insulators siv rau cov kab faib hluav taws xob tsawg thiab cov kab sib txuas lus. Cov insulators uas muaj hluav taws xob ntau yog cov insulators siv rau cov kab xa hluav taws xob siab, ultra-high-voltage overhead transmission kab thiab cov chaw hloov hluav taws xob. Yuav kom ua tau raws li qhov xav tau ntawm cov qib hluav taws xob sib txawv, cov lej sib txawv ntawm cov insulators ib leeg ntawm tib hom feem ntau yog siv los tsim cov hlua insulator lossis ntau ntu insulating struts.

7. Cov khoom siv tiv thaiv kev ua qias tuaj

Qhov kev ntsuas tseem ceeb yog kom nce lossis nthuav lub tsev lossis tav ntawm lub insulator kom nce qhov deb ntawm lub insulator kom txhim kho lub zog hluav taws xob ntawm lub insulator hauv qhov xwm txheej qias neeg. Tib lub sijhawm, cov qauv thiab cov duab ntawm lub tsev kuj raug hloov pauv kom txo qhov kev sib sau ua ke ntawm cov pa phem ntawm qhov chaw kom txhim kho kev ua haujlwm tiv thaiv kev ua qias tuaj ntawm lub insulator.

Qhov piv ntawm cov insulators uas tiv taus pa phem feem ntau yog 20% ​​txog 30% siab dua li cov insulators ib txwm muaj, lossis ntau dua. Cov insulators uas tiv taus pa phem uas zoo li lub kaus ob txheej siv rau hauv thaj chaw uas muaj pa phem ntau zaus hauv Suav teb lub zog hluav taws xob. Cov insulators no muaj peev xwm ntxuav nws tus kheej zoo thiab yooj yim ntxuav tes.

8. DC insulator

Feem ntau yog hais txog cov disc insulators siv rau hauv DC kis. DC insulators feem ntau muaj qhov ntev dua li AC pollution-resistant insulators, thiab lawv cov insulators muaj volume resistivity siab dua, thiab lawv cov khoom siv txuas yuav tsum tau nruab nrog cov electrodes sacrificial uas tiv thaiv electrolytic corrosion.
