Tshooj 2– Kev Taw Qhia ntawm Insulator
Tsawg-voltage insulators yog siv rau rwb thaiv tsev thiab dai cov xov hlau nyob rau hauv low-voltage thiab ultra-low voltage ac thiab dc kis kab.Nyob rau ntawm ib kawg ntawm high-voltage hlau txuas ntauwd, ntau disc-shaped insulators tau dai.Nws yog ua kom lub creepage nrug.
Tshooj 3 – Cov yam ntxwv ntawm Insulator
1) tus nqi xoom yog tawg los ntawm nws tus kheej, uas yooj yim rau kev tshawb nrhiav.
Iav insulator muaj tus yam ntxwv ntawm xoom tus nqi nws tus kheej - tawg.Raws li ntev raws li nyob rau hauv av los yog nyob rau hauv lub nyoob hoom qav taub yuav tsum tau soj ntsuam, tsis muaj yuav tsum tau rau mount tus ncej los ntawm piece nrhiav kom tau, txo cov kev siv zog ntawm cov neeg ua haujlwm.Rau cov khoom qhia rau hauv cov kab ntau lawm, txhua xyoo khiav tus kheej tawg tus nqi yog 0.02-0.04%, uas tuaj yeem txuag tau tus nqi txij nkawm ntawm kab.
2) zoo arc thiab kev co kuj
Qhov chaw tshiab ntawm cov iav insulator raug hluav taws kub kub thaum lub sijhawm ua haujlwm tseem du vitreous thiab muaj cov txheej txheem tiv thaiv kev ntxhov siab sab hauv, yog li nws tseem khaws cov rwb thaiv tsev txaus lub zog thiab cov neeg kho tshuab lub zog.In 500kv kab, muaj ntau yam kev puas tsuaj los ntawm cov dej khov. nyob rau hauv cov hlau, thiab cov neeg kho tshuab thiab hluav taws xob kev ua tau zoo ntawm lub iav insulator tom qab cov hlau seev cev tau sim.
3) Kev ua haujlwm zoo ntawm tus kheej thiab tsis yooj yim rau kev laus
Raws li daim ntawv tshaj tawm dav dav ntawm lub zog hluav taws xob, iav insulators tsis yooj yim rau cov pa phem thiab yooj yim los ntxuav.Qhov kev ua tau zoo ntawm cov iav insulators ntawm cov kab hauv cheeb tsam raug ntsuas los ntawm cov qauv tsis tu ncua, thiab cov ntaub ntawv ntau txhiab tus tau pom. tias cov khoom siv hluav taws xob thiab hluav taws xob ua haujlwm ntawm cov iav insulators tom qab 35 xyoo ntawm kev ua haujlwm yog qhov zoo ib yam li thaum lawv tawm hauv lub Hoobkas, thiab tsis muaj qhov tshwm sim ntawm kev laus.
4) lub peev xwm loj loj, tsis sib xws ntawm qhov hluav taws xob hauv series.
Iav ua rau lub dielectric tas li ntawm 7-8, toughened iav insulator muaj ib tug loj capacitance thiab cov hlua ntawm lub ntsiab uniform voltage tis, txo grounding hlau sab thiab insulator nyob ze voltage, thiaj li yuav txo tau cov xov tooj cua cuam tshuam, txo corona poob. thiab ncua lub neej kev pab cuam ntawm iav insulator, lub hom phiaj ntawm kev xyaum ua pov thawj qhov no
Tshooj 4 – Insulator tiv thaiv txheej txheem
Tam sim no, kev tiv thaiv xob laim ntawm txoj kab yog feem ntau rau nruab zinc oxide ntes, tab sis daim ntawv thov ntawm zinc oxide ntes kuj muaj cov teeb meem hauv qab no:
(1) tom qab zinc oxide ntes tau tawg lossis puas los ntawm xob laim, lub qhov ncauj puas me me thiab nyuaj rau kev saib xyuas thiab nrhiav.
(2) zinc oxide ntes yuav tsum tau kuaj ib zaug ib zaug txhua 3 ~ 5 xyoos, thiab qhov kev sim ua haujlwm loj dhau.
(3) zinc oxide ntes yuav tsum tau ua hauv av, thiab tus nqi ntawm kev tsim kho thiab kev saib xyuas yog qhov siab heev.
(4) piv nrog cov insulator, tus nqi yog siab, uas tsis haum rau kev siv loj.
Lub hom phiaj ntawm cov teeb meem saum toj no, cov cuab yeej tiv thaiv xob laim ntawm insulator yog tsim.Tom qab kev soj ntsuam, nws tau txiav txim siab tias cov qauv huab cua sib txawv yog qhov yooj yim thiab tus nqi qis.Qhov zoo ntawm huab cua sib txawv ua rau siv cov yam ntxwv ntawm lub zog-zaus arc. Nws yog ib qho yooj yim txav mus los nyob rau hauv qhov kev txiav txim ntawm nws tus kheej hluav taws xob quab yuam thiab cov roj kub tam sim no, thiab ua rau lub arc elongate, yog li ua rau lub arc extinguished.Yog li ntawd, ib tug insulator xob tiv thaiv ntaus ntawv muaj li ntawm arc qhia clamp, zoo ncej pas nrig thiab tsis zoo phaj yog tsim, thiab cov qauv hloov tau raug saws los cais arc qhia clamp thiab tus ncej zoo, thiab bolt ua ke yog saws.
Yog hais tias tus pas nrig zoo raug puas los ntawm arc combustion, tus pas nrig zoo tuaj yeem hloov pauv ntawm tag nrho cov teeb, uas txo tus nqi.
