Kev paub dav dav ntawm Insulator Strings

Lub luag haujlwm tseem ceeb ntawm txoj hlua hluav taws xob yog txhawm rau txhawb nqa thiab txhim kho cov neeg nqa khoom tam sim no, thiab tsim kom muaj kev rwb thaiv tsev zoo ntawm cov neeg nqa khoom tam sim no thiab hauv av. Lub insulator (feem ntau hu ua porcelain vase) yog tsim los ntawm ob qhov chaw: porcelain qhov chaw thiab cov khoom siv, uas yog sib txuas nrog cov cement kua nplaum nyob rau hauv nruab nrab. Cov khoom siv plooj (porcelain) yog siv los xyuas kom meej lub zog hluav taws xob zoo ntawm lub insulator, thiab cov khoom siv yog siv los kho cov insulator.
Tempered iav insulators yog ib hom tshwj xeeb ntawm kev tiv thaiv rwb thaiv tsev uas tuaj yeem ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob. Insulators ua si ob lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov neeg siv khoom thiab tiv thaiv tam sim no rov qab los rau hauv av. Ob lub luag haujlwm tseem ceeb no yog cov insulators tuaj yeem muab cov rwb thaiv tsev zoo heev.
Insulators tsis tsuas yog yuav tsum tau dais qhov hnyav ntawm cov khoom thauj khoom, cov xov hlau, thiab cov khoom siv hlau, tab sis kuj tuaj yeem tiv thaiv qhov cuam tshuam los ntawm cua, daus, hlau seev cev, thiab kev ua haujlwm tsis raug thaum lub sijhawm thauj mus los thiab kev teeb tsa hauv huab cua tsis zoo. Lawv tuaj yeem tiv taus hnyav dua. Los ntawm kev xav ntawm hluav taws xob, insulators tsis tsuas yog yuav tsum tau insulate lub conductors los ntawm hauv av, tab sis kuj tiv taus overvoltage surges los ntawm xob laim thiab switching ua hauj lwm.
Thaum voltage surge tshwm sim, lub zos overheating yuav tsis ua rau lub tempered iav ntawm lub insulator tawg, thiab tag nrho cov sab nraud yam yuav cuam tshuam rau kev ua tau zoo ntawm lub insulator. Yog li ntawd, cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau kev tsim cov iav insulators, uas yuav tsum tau kho kom nruj thiab muaj kev tsim qauv nruj thiab siv lub hauv paus.
Rau qhov kev ntsuam xyuas lub zog ntawm cov hlua hluav taws xob, lub tshuab hluav taws xob khoov thiab torsion kuaj tau raug xaiv los ua kom tiav qhov kev xeem. Kev kuaj xyuas hluav taws xob thiab hluav taws xob puas tsuaj yog qhov taw qhia tseem ceeb rau kev kuaj xyuas cov insulators. Tom qab 15 mus rau 25 xyoo ntawm kev ua haujlwm, qhov ntsuas tus nqi ntawm ceramic insulators yog qis dua lub Hoobkas kuaj tus qauv tus nqi, thiab tus nqi tsis ua haujlwm nce ntxiv nrog rau kev pabcuam lub neej. Txawm li cas los xij, kev ruaj ntseg thiab tawg ntawm cov iav insulators yog qhov zoo dua li cov khoom siv hluav taws xob ceramic, Kev ntsuas kev vibration ntau zaus tau ua rau cov porcelain thiab iav insulator hlua. Cov txiaj ntsig kev sim tau pom tias lub zog ntawm cov iav thiab hluav taws xob ntawm cov iav insulators tsis hloov pauv ntau tom qab kev co, thaum lub zog ntawm cov khoom siv hluav taws xob thiab hluav taws xob ntawm cov plooj (porcelain insulator strings) poob qis tom qab kev vibration, feem ntau yog vim li cas xws li kev tsim technology.
Yog tias cov hlua hluav taws xob sib xyaw raug tshem tawm tom qab xyoo ntawm kev ua haujlwm thiab pom tias lub zog ntawm cov khoom siv hluav taws xob tau txo qis mus rau qhov sib txawv, qee qhov mandrels swb nyob rau hauv cov khoom siv ntsuas ntsuas, qee qhov mandrels tshem tawm ntawm qhov kawg fittings, thiab qee qhov mandrels tawg. vim muaj teeb meem nrog cov qauv txiav thiab txheej txheem; Cov yam ntxwv creep ntawm cov tub ntxhais pas nrig thiab kev laus ntawm cov khoom. Thaum lub sijhawm ua haujlwm ntev, vim muaj kev sib xyaw ua ke ntawm huab cua ib puag ncig, hluav taws xob, thiab kev siv tshuab, cov iav fibers hauv cov pwm pwm yuav muaj kev qaug zog, cov khoom siv epoxy resin yuav muaj hnub nyoog, thiab kev sib txuas ntawm qhov kawg fittings. core pwm yuav xoob.
Muaj ob hom hluav taws xob ua haujlwm tsis zoo ntawm cov hlua insulator: flashover thiab tawg. Ob hom hluav taws xob kev ua haujlwm tsis zoo yog hom kev ua txhaum sib txawv thiab muaj ntau txoj kev txhaum. Flashover tshwm sim nyob rau saum npoo ntawm cov hlua insulator, nrog pom cov cim ntawm kev raug mob. Feem ntau, tsis muaj qhov poob ntawm rwb thaiv tsev kev ua tau zoo, thaum tawg tshwm sim hauv cov hlua insulator. Cov plooj (porcelain) lub cev tawm ntawm lub hau hlau thiab hlau ko taw, thiab qhov zoo li yuav tsis pom, tab sis qhov kev ua haujlwm rwb thaiv tsev tau ploj lawm.
