Hauv kev xaiv tiag tiag thiab kev siv ntawm ultra-high voltage (UHV) tej yaam num, yam xws li kev khiav hauj lwm ib puag ncig thiab kev nyab xeeb kev nyab xeeb yuav tsum tau txiav txim siab tag nrho. Disc-hom ncua kev kawm ntawv porcelain insulators yog puncture-cov insulators nquag, thiab deterioration tshwm sim nrog nce lub sij hawm ua hauj lwm, muaj peev xwm tig mus rau hauv qis- nqi lossis xoom- tus nqi insulators. Thaum xob laim los yog muaj kuab paug flashovers tshwm sim ntawm cov hlua insulator uas muaj tsawg - cov nqi insulator discs, lub zog zaus ua raws li tam sim no dhau los ntawm lub taub hau ntawm qhov qis- tus nqi insulator discs yuav ua rau cov kaus mom hlau tawg, cov hlua insulator tawg, lossis txawm tias tus neeg xyuas pib poob rau hauv av-a Porcelain insulators puas los ntawm xob laim ntaus nrog tev glaze yuav tsum tau hloov.
Cov Ntsiab Cai Kev Xaiv: Rau cov chaw muaj kuab paug me me, ob- lub kaus hom porcelain insulators lossis iav zoo tib yam tuaj yeem siv rau cov hlua ncua kev kawm, V- hlua hlua, thiab cov hlua nro. Rau cov cheeb tsam nruab nrab lossis muaj kuab paug hnyav, cov khoom siv hluav taws xob feem ntau yog siv rau cov hlua khi thiab V- cov hlua hlua, thaum ob npaug -kaum hom porcelain insulators lossis cov iav zoo tib yam yog qhov zoo dua rau cov hlua nruj. Hauv cov cheeb tsam uas ua rau hnyav icing, kev ua tau zoo ntawm cov khoom siv insulators deteriorates ho tom qab icing. Yog li ntawd, ob -kaum porcelain insulators lossis iav zoo tib yam yog qhov nyiam, nrog cov hlua khi, V- cov hlua, thiab cov hlua nro tag nrho cov kev xaiv tsim nyog. Hauv qhov siab- qhov siab siab, cov khoom siv hluav taws xob feem ntau yog siv rau kev ncua thiab V- cov hlua, thaum ob npaug - lub kaus porcelain insulators lossis cov iav zoo tib yam yog nyiam rau cov hlua nro. Triple-umbrella porcelain insulators muaj kev tiv thaiv zoo dua rau cov pa phem flashover, tab sis lawv cov qauv siv ntau dua thiab cov nqi siab dua txwv lawv cov ntawv thov siv dav dav piv rau ob npaug -umbrella porcelain insulators.
Daim ntawv thov tshwj xeeb: Ncua tseg hauv av porcelain insulators rau overhead xob laim tiv thaiv cov xov hlau tuaj yeem siv rau hauv siab -voltage lossis ultra-siab-voltage kis kab. Nyob rau hauv ib txwm ua hauj lwm voltage, xob laim tiv thaiv hlau yog insulated los ntawm hauv av, zoo txo lub zog poob nyob rau hauv lub kis kab mob thiab tso cai rau kev sib txuas lus. Nyob rau hauv atmospheric overvoltage, qhov kev tiv thaiv qhov sib txawv conducts, grounding lub xob laim tiv thaiv hlau thiab zoo tiv thaiv kab thiab khoom siv.
