Cov lus nug ntawm kev nkag siab zoo hauv cov rwb thaiv tsev, thov nyem

Lub luag haujlwm tseem ceeb ntawm cov hlua hluav taws xob yog ua kom ruaj khov thiab txhim kho cov cab kuj -flow conductor, thiab tsim cov rwb thaiv tsev zoo ntawm cov neeg xyuas pib thiab hauv av. , Porcelain pieces yog siv los xyuas kom meej zoo hluav taws xob rwb thaiv tsev lub zog ntawm insulators, thiab cov cuab yeej kub yog siv rau ruaj insulators.

Steel iav insulators yog ib qho kev tiv thaiv tshwj xeeb uas tuaj yeem ua lub luag haujlwm tseem ceeb hauv cov kab hluav taws xob siv hluav taws xob. Lub insulator plays ob lub luag haujlwm tseem ceeb hauv cov kab hluav taws xob siv hluav taws xob, uas yog, txhawb cov xov hlau thiab tiv thaiv tam sim no rov qab los rau hauv av. Ob lub luag haujlwm tseem ceeb no yog ob txoj haujlwm tseem ceeb no. Lub insulator tuaj yeem muaj qhov cuam tshuam zoo rwb thaiv tsev.

Lub insulator yuav tsum tsis tsuas yog dais qhov hnyav ntawm txhua yam load hlau thiab hlau txuas, tab sis kuj yuav tiv thaiv qhov cuam tshuam los ntawm cov khoom siv cua, daus loads, hlau seev cev, kev thauj mus los hauv huab cua hnyav, kev ua haujlwm tsis zoo thaum lub sijhawm teeb tsa, thiab lwm yam. insulator yuav tsum tsis tsuas yog ua rau tus neeg xyuas pib thiab hauv av sab hauv, tab sis kuj tiv taus lub overvoltage shock tshwm sim los ntawm xob laim thiab hloov kev ua haujlwm.

Thaum qhov hluav taws xob cuam tshuam tshwm sim, lub hauv paus overheating yuav tsis ua rau cov insulators yog tempered iav, thiab tag nrho cov sab nraud yuav cuam tshuam rau kev ua tau zoo ntawm insulators. Yog li ntawd, kev tsim cov iav insulator yog siab dua. Muaj kev tsim qauv nruj thiab siv lub hauv paus.

Rau qhov kev ntsuam xyuas lub zog ntawm cov hlua hluav taws xob, xaiv qhov khoov thiab thim rov qab kev sim tshuab ntawm cov insulators kom tiav qhov kev xeem. Kev kuaj mob electromechanical raug mob yog ib qho tseem ceeb qhia txog kev kuaj xyuas insulator. Tom qab 15-25 xyoo, qhov kev xeem tus nqi ntawm cov porcelain rwb thaiv tsev yog qis dua tus qauv tus nqi ntawm lub Hoobkas kuaj kev xeem. , Tus nqi tsis ua hauj lwm nce nrog lub sijhawm khiav, tab sis kev ruaj ntseg thiab kev faib tawm ntawm cov iav insulators zoo dua li cov khoom siv hluav taws xob porcelain. Cov porcelain rwb thaiv tsev skewers thiab iav insulator skewers tau ua qhov kev ntsuam xyuas siab-frequency vibration fatigue tests. Lub zog hluav taws xob tsis tau hloov pauv ntau, thiab lub zog txhua yam thiab lub zog hluav taws xob ntawm cov plooj (porcelain insulation) poob qis heev tom qab txoj hlua vibration, lub ntsiab yog vim li cas cov txheej txheem tsim khoom yog qhov tseem ceeb.

Yog tias cov hlua hluav taws xob sib txuas tau raug rhuav tshem tom qab ntau xyoo ntawm kev ua haujlwm, lub zog ntawm cov khoom siv hluav taws xob tau txo qis mus rau qhov sib txawv, thiab qee lub plawv shafts poob qis ntawm cov khoom ntsuas ntsuas. Muaj teeb meem nrog cov qauv thiab kev siv tes ua haujlwm; Cov yam ntxwv ntawm cov core stick thiab aging ntawm cov ntaub ntawv, nyob rau hauv lub sij hawm ntev kev ua hauj lwm, vim muaj kev cuam tshuam ntawm atmospheric ib puag ncig, hluav taws xob teb thiab mechanical zog, lub iav fiber nyob rau hauv cov tub ntxhais pwm yuav ua rau txhua yam qaug zog, epoxy resin. cov ntaub ntawv Nws yuav laus, thiab kev sib txuas ntawm cov iav kub thiab cov tub ntxhais pwm yuav xoob.

Muaj ob hom hluav taws xob ua haujlwm tsis ua haujlwm ntawm cov hlua insulator. Muaj ob hom flash collaterals thiab tawg. Qhov kev ua txhaum ntawm ob qho kev ua txhaum ntawm hluav taws xob yog qhov sib txawv, thiab txoj kev faulty txawv. Qhov saum npoo ntawm txoj hlua insulator tshwm sim. Thaum pib, cov plooj (porcelain) raug tso tawm ntawm cov kaus mom hlau thiab cov taw hlau. Cov tsos mob yuav tsis pom, tab sis qhov kev ua haujlwm rwb thaiv tsev tau ploj lawm.
