Raws li cov khoom siv hluav taws xob tseem ceeb hauv lub zog hluav taws xob, tag nrho kev ua haujlwm thiab kev pabcuam lub neej ntawm switchgear feem ntau nyob ntawm cov khoom siv tseem ceeb. Cov khoom sib txawv xav tau kev ua haujlwm sib txawv, yuav tsum xaiv cov khoom siv tshwj xeeb, hluav taws xob, thiab kev hloov pauv ib puag ncig kom ua tiav lub hom phiaj ntawm kev ruaj ntseg, txhim khu kev qha, thiab kev ua haujlwm ruaj khov.
Lub txee thiab thav duab feem ntau yog tsim los siv siab -zoo txias- dov steel los yog galvanized steel los xij. Txias- cov ntawv yob steel muaj lub zog siab thiab zoo formability, yooj yim rau kev ua cov txheej txheem nyuaj kom ua tau raws li kev tiv thaiv thiab cov txheej txheem sab hauv; galvanized steel sheets tsim ib txheej zinc rau ntawm qhov chaw, ua kom muaj kev tiv thaiv corrosion thiab ua rau lawv haum rau ib puag ncig nrog cov av noo siab lossis corrosive media. Qee qhov tshwj xeeb - lub hom phiaj switchgear kuj siv cov ntawv hlau stainless los tiv thaiv cov xwm txheej hnyav ntawm ntug dej hiav txwv ntsev los yog cov nroj tsuag tshuaj, muab kev tiv thaiv corrosion zoo dua thiab lub zog muaj zog.
Cov ntaub ntawv rwb thaiv tsev yog ib qho tseem ceeb hauv kev ua kom muaj kev ruaj ntseg hluav taws xob hauv switchgear. Cov khoom siv feem ntau suav nrog epoxy resin, SMC molding compound, thiab siab -kev ua tau zoo engineering yas. Epoxy resin muaj cov khoom siv hluav taws xob zoo heev thiab cov khoom siv dag zog, thiab feem ntau yog siv rau kev sib khi ncej, insulators, thiab bushing Cheebtsam. SMC molding tebchaw muaj cov cua sov zoo thiab cov nplaim hluav taws kub hnyiab, ua rau lawv tsim nyog rau kev tsim cov khoom siv hluav taws xob loj xws li partitions thiab panels. Engineering plastics xws li polycarbonate thiab nylon, vim lawv lub teeb yuag, kev cuam tshuam, thiab kev yooj yim ntawm kev ua, feem ntau yog siv rau qhov taw qhia lub teeb npog, kev khiav hauj lwm tuav, thiab cov khoom siv insulating me me.
Cov khoom siv hluav taws xob feem ntau yog ua los ntawm siab -purity electrolytic tooj liab lossis tooj liab alloys, vim lawv cov conductivity siab thiab muaj zog oxidation tsis kam, uas tuaj yeem txo qhov kev tiv thaiv thiab lub zog poob. Busbars feem ntau siv tooj liab busbars nrog tin los yog nyiaj plating los txhim kho corrosion kuj thiab conductivity. Cov ntaub ntawv tiv tauj feem ntau yog nyiaj -raws li alloys, uas ua ke zoo heev conductivity thiab hnav tsis kam los xyuas kom ruaj khov kev sib cuag thaum lub sij hawm ua hauj lwm nquag.
Kev sib khi thiab kev tiv thaiv feem ntau siv cov ntaub ntawv elastic xws li EPDM roj hmab thiab silicone roj hmab, uas muaj huab cua zoo, roj tsis kam, thiab kub tsis kam, tiv thaiv kev nkag mus ntawm cov dej noo, plua plav, thiab cov pa phem, thiab tswj kom muaj kev ruaj ntseg hauv lub txee.
Hauv cov ntsiab lus, kev xaiv cov khoom siv rau switchgear yuav tsum muaj qhov sib npaug ntawm cov khoom siv dag zog, kev ua haujlwm hluav taws xob, kev tiv thaiv ib puag ncig, thiab kev lag luam. Rau cov xwm txheej sib txawv, kev sib xyaw tsim nyog ntawm cov qauv hlau, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob tuaj yeem tsis tsuas yog txhim kho cov cuab yeej kev ntseeg tau tab sis kuj muab cov khoom lav rau kev ua haujlwm ruaj ntseg thiab ruaj khov ntawm lub zog hluav taws xob.
