Raws li cov cuab yeej tseem ceeb hauv lub zog hluav taws xob ua lub luag haujlwm rau kev hloov hluav taws xob thiab kev sib cais tsis raug, qhov tshwm sim ntawm siab -voltage switchgear yog qhov tshwm sim los ntawm kev sib xyaw ua ke ntawm cov khoom siv, kev tsim qauv, thiab kev ua haujlwm ib puag ncig uas yuav tsum tau ua. Los ntawm tag nrho cov txheej txheem mus rau cov ncauj lus kom ntxaws kev tsim kho, txhua qhov tshwm sim ua haujlwm rau lub hom phiaj ntawm kev ua haujlwm hluav taws xob, kev nyab xeeb kev ua haujlwm, thiab kev saib xyuas yooj yim.
Los ntawm qhov kev xav macroscopic, siab -voltage switchgear feem ntau nthuav tawm peb yam zoo li pawg: lub thawv- hom, qhib - hom, thiab kaw - hom. Lub thawv- hom qauv yog feem ntau cov duab plaub lub cev welded los yog sib dhos los ntawm cov hlau phaj, nrog cov plhaub tiaj tus thiab cov npoo ntse. Qhov saum npoo yog kho nrog cov tshuaj tiv thaiv- xeb xeb, thiab cov xim feem ntau yog xim grey, ceeb toom daj, lossis cov xim qub ntawm cov khoom siv, ua tau raws li qhov yuav tsum tau ua rau huab cua tiv thaiv sab nraum zoov thiab txheeb xyuas cov khoom siv los ntawm cov lus sib koom ua ke. Qhib- hom qauv feem ntau pom muaj nyob rau hauv cov khoom siv hluav taws xob faib hluav taws xob lossis cov chaw sim, nrog rau qhov chaw nyob raug huab cua. Lub moj khaum muaj cov insulators, kev txhawb nqa, thiab busbars, ua kom pom tseeb dua thiab yooj yim rau kev soj ntsuam ntawm kev sib cuag thiab kev sib txuas. Txawm li cas los xij, muaj kev txwv nruj ntawm ib puag ncig thiab kev nyab xeeb nyob deb. Cov txheej txheem kaw kom kaw cov khoom siv sab hauv hauv lub thawv hlau lossis lub plhaub plhaub. Lawv feem ntau yog cylindrical lossis lub thawv ntawv nrog lub ntsej muag huv si, ua kom pom tseeb, qhia txog kev tsim lub tswv yim ntawm kev sib koom ua ke siab thiab kev tiv thaiv muaj zog.
Cov khoom siv plhaub thiab kev kho saum npoo yog qhov tseem ceeb ntawm cov tsos. High-voltage switchgear shells feem ntau yog ua los ntawm siab- zoo carbon steel, stainless hlau, los yog aluminium alloy, ua ntej- kho nrog sandblasting thiab phosphating ua ntej electrostatic hmoov txheej los yog kub-dip galvanizing los txhim kho corrosion kuj, UV aging kuj, thiab txhua yam hnav tsis kam. Qee cov cuab yeej siv nyob rau hauv marine lossis tshuaj ib puag ncig kuj muaj cov tshuaj tiv thaiv - ntsev thiab tshuaj tiv thaiv - cov tshuaj tiv thaiv corrosion, ua rau lub ntsej muag du thiab ntev - xim. Lub plhaub pob qij txha thiab cov ces kaum yog tsim los rau kev sib hloov thiab kev sib khi, tiv thaiv plua plav thiab dej sib sau ua ke thiab txo qhov kev pheej hmoo ntawm kev sib tsoo rau cov neeg ua haujlwm.
Saib xyuas cov ncauj lus kom ntxaws, cov kev sib tshuam thiab cov cim cim ntawm high -voltage switchgear muaj cov yam ntxwv tshwj xeeb. Bushings thiab busbar interfaces feem ntau yog ua los ntawm ceramic los yog cov ntaub ntawv insulating, nrog ib tug columnar los yog conical zoo. Lawv tau nruab nrog cov hlau flanges thiab fastening bolts ntawm qhov kawg, npaj kom huv si thiab symmetrically nrog lub plhaub axis, ua tau raws li qhov yuav tsum tau muaj hluav taws xob rwb thaiv tsev nyob deb thaum ua kom yooj yim ntawm - qhov chaw teeb tsa thiab kev sib txuas. Cov khoom siv saum npoo feem ntau muaj cov ntawv teev npe, cov ntawv ceeb toom, thiab cov lus qhia ua haujlwm. Nameplates kom meej meej qhia qhov tseem ceeb tsis xws li ntsuas voltage, tam sim no, thiab cov ntaub ntawv tsim khoom, nrog cov ntawv sau meej thiab ruaj khov. Cov ntawv ceeb toom siv kev sib txuas ntawm cov duab thiab cov ntawv los qhia txog thaj chaw muaj kev phom sij, kev ua haujlwm tsis raug cai, thiab kev saib xyuas kev ceev faj, nrog rau cov xim sib txawv kom yooj yim ntev - txheeb xyuas qhov deb.
Kev tsim cov khoom siv ua haujlwm qhia txog kev nyab xeeb thiab kev paub txog tib neeg - tshuab kev sib cuam tshuam. Kev tuav tuav haujlwm, cov nyees khawm, lossis cov pob qhov rooj feem ntau yog nyob rau pem hauv ntej lossis sab qis ntawm cov khoom siv, nrog cov duab ergonomic, kom paub meej qhov txawv ntawm kev tiv thaiv -slip textures thiab xim, thiab cov khoom siv thaum muaj xwm ceev tripping tau pom muaj xim liab thiab tiv thaiv los ntawm kev tiv thaiv npog kom tiv thaiv kev ua txhaum cai. Rau cov khoom siv hluav taws xob ua haujlwm, lub cev muaj zog, kis tau tus mob gearbox, thiab txwv kev hloov pauv yog pom sab nraud, thiab lub casing muaj qhov cua grilles los pab kom muaj cua sov; cov duab thiab qhov ntom ntawm cov hniav nyiaj hniav kub sib npaug tiv thaiv qib thiab cov kev xav tau ntawm airflow.
Nyob rau hauv siab -voltage switchgear (xws li GIS) muaj qhov tshwj xeeb zoo li, zoo li lub kaus mom kaw nrog ob peb qhov chaw nyob. Kev soj ntsuam qhov rais lossis ntsuas ntsuas siab tsuas yog muab tso rau hauv qhov chaw tsim nyog. Lub casing welds yog zoo thiab xau- sim siv helium huab hwm coj spectrometry los xyuas kom meej airtightness. Nws qhov yooj yim thiab zoo nkauj tsos tsis tsuas yog txuag tau qhov chaw tseem ceeb, tab sis kuj qhia txog kev lag luam niaj hnub zoo nkauj ntawm kev ntseeg siab thiab kev saib xyuas qis los ntawm nws cov qauv tsim.
Zuag qhia tag nrho, qhov zoo li ntawm siab -voltage switchgear yog ib qho kev xav txog kev ua haujlwm, kev nyab xeeb, thiab ib puag ncig: kev ruaj khov ntawm lub qhov rooj thiab cov kav ntev ntawm cov txheej kom ntev - lub sij hawm ruaj khov nyob rau sab nraum zoov thiab tshwj xeeb kev ua haujlwm; qhov zoo ntawm cov interfaces thiab qhov pom tseeb ntawm cov cim txhim kho kev ua haujlwm ntawm kev teeb tsa thiab kev saib xyuas; thiab kev txheeb xyuas yooj yim thiab kev tiv thaiv ntawm cov haujlwm ua haujlwm tseem ceeb qhia txog tib neeg -lub tswv yim tsim qauv. Cov ntsiab lus zoo li no ua ke tsim cov duab pom zoo ntawm cov khoom siv thiab ncaj qha cuam tshuam nws qhov tseem ceeb ntawm kev tswj hwm kev nyab xeeb hauv lub zog.
