Ua tiav kev tshuaj xyuas ntawm cov kev paub tseem ceeb ntawm Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob rau siab -voltage switchgear, lub nplhaib lub ntsiab thiab lub hauv paus txee

Ntawm peb qhov kev qhuab qhia loj ntawm kev siv tshuab thiab hluav taws xob (dej, cua sov, thiab hluav taws xob), hluav taws xob engineering muaj cov yam ntxwv sib txawv. Cov cuab yeej tseem ceeb ntawm kev lag luam dej thiab cua sov feem ntau yog nyob ntawm cov khoom siv hluav taws xob xws li cov twj tso kua dej thiab cov kiv cua, uas xa cov teeb meem thiab lub zog los ntawm lub zog; Lub tsib qhov txuas tseem ceeb ntawm kev tsim hluav taws xob, xws li kev sib kis, kev hloov pauv, kev faib tawm, thiab kev siv, txhua tus cia siab rau ntau yam Sab nraum zoov huab cua tsis zoo hauv lub thawv txee (tseem hu ua "boxes" lossis "enclosures" nyob ntawm lawv qhov loj) hauv kev siv tswv yim. Tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem kev faib hluav taws xob thiab kev siv hluav taws xob, cov khoom siv hluav taws xob ua lub luag haujlwm tseem ceeb -cov kabmob, tsim cov qauv ntawm "tsis muaj txee, tsis muaj qhov system".

Ntau yam khoom siv hluav taws xob sab nraum zoov tsim lub zog faib hluav taws xob uas xa hluav taws xob rau ntau tus neeg siv kawg. Rau cov kws tshaj lij uas tsis yog hluav taws xob, cov khoom siv hluav taws xob sab nraum zoov tsuas yog nthuav tawm nyob rau hauv daim ntawv ntawm cov khoom sib txuas lossis cov thawv rau ntawm cov duab kos, uas ua rau muaj kev nkag siab tsis meej; Tab sis rau cov kws tshaj lij hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv, thiab cov qauv hluav taws xob hauv lub txee yog qhov tseem ceeb, thiab lub txee nws tus kheej feem ntau ua haujlwm rau kev teeb tsa thiab kev txhawb nqa.

Nrog rau txoj kev loj hlob ntawm thev naus laus zis, Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob, raws li tus neeg nqa khoom tseem ceeb rau cov tshuab hluav taws xob tag nrho, tau txais txiaj ntsig nrog ntau lub zog. Tsuas yog cov khoom tseem ceeb ntawm lub hauv paus tseem ceeb, cov khoom siv pabcuam, cov khoom siv tswj xyuas, cov khoom siv saib xyuas thib ob, thiab lwm yam. Yog li, kev paub txog cov npe, kev ua haujlwm, thiab cov yam ntxwv ntawm ntau yam ua tiav ntawm cov khoom siv hluav taws xob yog tus yuam sij kom tsis txhob muaj kev ntxhov siab hauv kev siv thiab tiv thaiv kev nyab xeeb.

High voltage switchgear yog ib lub ntsiab lus dav dav hauv kev siv hluav taws xob siab (qhov nruab nrab voltage) lub zog hluav taws xob thiab kev faib khoom, suav nrog ntau hom high / nruab nrab voltage tis thiab cov khoom tawg, nrog rau lub nplhaib tseem ceeb, cov khoom hauv nruab nrab (nruab nrab mounted txee), cov khoom siv hluav taws xob siab, cov khoom siv hluav taws xob siab, thiab lwm yam. fais fab mov thiab faib system.

Raws li cov qauv tsim, siab -voltage switchgear feem ntau yog muab faib ua taag thiab nruab nrab mounted hom. Ntawm lawv, hom taag (xws li GG-1A hom) yog maj mam hloov los ntawm nruab nrab mounted hlau enclosed switchgear (xws li KYN-18 series), uas yog dav siv vim nws zoo heev mechanical kev ua tau zoo thiab kev nyab xeeb thiab kev cia siab rau.

Hluav taws xob txee sab nraum zoov nrog cov qauv sib txawv yog tsim rau cov xwm txheej sib txawv thiab cov kev xav tau siv. Hauv kev siv cov tswv yim, siab -voltage switchgear thiab lub nplhaib tseem ceeb feem ntau yog tsom rau cov khoom siv hluav taws xob, thaum nruab nrab cov khoom siv (tseem hu ua cov khoom siv tes tuav) tsom rau kev tiv thaiv kev thauj khoom. Peb hom ntawm cov txee muaj kev faib tawm ntawm kev ua haujlwm kom sib koom ua haujlwm ruaj khov ntawm cov khoom siv hluav taws xob thiab kev faib khoom.

Mid mounted switchgear, tseem hu ua hlau armored mid mounted rho tawm switchgear, belongs rau siab -voltage tis khoom. Raws li ib qho tseem ceeb ntawm high-voltage Hluav taws xob cov txee los ua ke, nws qhov siab tshaj plaws kev khiav hauj lwm voltage yog 3.6/7.2/12kV, haum rau sab hauv tsev tag nrho faib ntawm peb-theem AC 50Hz, ib lub tsheb npav segmented los yog ob lub tsheb npav segmented systems. Feem ntau yog siv rau kev sib kis ntawm me me thiab nruab nrab- cov tshuab hluav taws xob loj hauv cov chaw tsim hluav taws xob, kev sib kis ntawm cov chaw nruab nrab hauv cov tshuab hluav taws xob, kev faib hluav taws xob hauv cov chaw lag luam thiab cov mining lag luam thiab cov cheeb tsam hauv nroog, nrog rau pib- nce siab ntawm lub zog loj -voltage motors. Cov qauv muaj xws li KYN28, KYN18, KYN61, thiab lwm yam.

Nws cov txheej txheem tseem ceeb yog peb - txheej txheej tsim: txheej sab sauv yog chav tsev busbar thiab chav ntsuas ntsuas (kev sib cais ntawm ib leeg), nruab nrab txheej yog chav hluav taws xob hluav taws xob, thiab txheej hauv qab yog chav cable. Lub npe tom qab lub Circuit Court breaker nyob rau hauv nruab nrab txheej, nws yooj yim rau kev khiav hauj lwm thiab txij nkawm ntawm lub hwj chim tswj txee.

Lub hauv paus txee tau muab faib ua cov qauv siab thiab qis thiab qhov sib npaug ntawm qhov siab: cov qauv siab thiab qis muaj qhov siab pem hauv ntej ntawm 2300mm thiab lub nraub qaum qhov siab ntawm 1920mm, nrog cov busbars teem rau hauv cov duab ntoo khaub lig thiab chav ntsuas ntsuas; Qhov siab ntawm cov qauv yog zoo ib yam ua ntej thiab tom qab, thiab cov busbars yog teem vertically thiab nyob rau hauv ib txoj kab ncaj nraim. Cov cuab yeej cuab tam yog kev koom ua ke nrog cov hlau hluav taws xob txee, muab qhov chaw loj dua thiab ua kom yooj yim rau kev tsim khoom thiab kev ua haujlwm.

Qhov tseem ceeb ntawm lub txee nruab nrab tam sim no yog kev teeb tsa ntawm microcomputer tiv thaiv cov cuab yeej, uas ua ke nrog kev tiv thaiv, ntsuas, saib xyuas, kev sib txuas lus thiab lwm yam haujlwm. Nws txais cov qauv tsim qauv thiab tuaj yeem hloov cov khoom siv ib txwm siv thiab ntsuas ntsuas, ua kom yooj yim rau theem nrab tsim thiab kev tsim kho, txuag chaw teeb tsa thiab tswj cov cables, thiab txhim kho qib kev txawj ntse ntawm lub txee hluav taws xob.

Txawm hais tias muaj kev sib tshuam ntawm nruab nrab mounted txee thiab cov high -voltage switchgear, lawv daim ntawv thov scenarios thiab functional positioning muaj lawv tus kheej tsom, thiab hluav taws xob tswj txee yuav tsum tau xaiv kom tsim nyog raws li qhov xav tau tiag tiag. Qhov sib txawv yog feem ntau xav txog hauv tsib yam hauv qab no:

Ua ntej, lub ntsiab lus txawv. Mid mounted switchgear tshwj xeeb yog hais txog armored tshem tau mid mounted hlau enclosed switchgear, thaum siab -voltage switchgear yog ib lo lus dav dav rau cov khoom siv hluav taws xob nrog lub zog ua haujlwm ntawm 3.6kV txog 550kV, siv rau kev qhib / tawm, tswj, thiab kev tiv thaiv ntawm lub tshuab hluav taws xob, nrog rau ntau yam.

Qhov thib ob, txoj kev ruaj khov yog qhov sib txawv ntawm cov yam ntxwv hloov. Lub hauv paus txee yog ib tug detachable Circuit Court breaker (handcart type), thaum lub siab -voltage switchgear feem ntau yog ib tug ruaj load hloov.

Thib peb, cov haujlwm sib txawv. Lub hauv paus txee tsom rau siab-voltage load tiv thaiv, siv los tiv thaiv rov qab-kawg transformer thiab siab-voltage load; High voltage switchgear feem ntau yog siv rau siab -voltage tis, faib ib los yog ob siab -voltage fais fab qhov chaw mus rau hauv ntau cov kab tawm. Ob lub luag haujlwm ntxiv rau ib leeg thiab ua haujlwm ua ke.

Plaub, cov qauv sib txawv. Lub hauv paus txee txais yuav peb - txheej txheej txheej txheej, thiab feem ntau siab -voltage switchgear txuas nrog tooj liab busbars los ntawm SF6 load switches zoo tib yam los tsim ib qho system.

Thib tsib, muaj ntau hom kev muaj nyob. High voltage switchgear muaj ob daim ntawv: huab cua insulated thiab tag nrho cov roj ntim cov txee. Cov khoom ntim roj puv tag nrho txuas nrog rau ib leeg hauv chav ua kom tiav cov pa roj uas muaj SF6 roj, thiab tsis muaj qhov tshwm sim nyob rau hauv tshwj tsis yog cov txuas tshwj xeeb rau cov kab nkag thiab tawm.

Hauv cov ntsiab lus, txawm hais tias peb hom khoom muaj nyob rau hauv qeb siab -voltage Sab nraud hluav taws xob txee, txhua tus muaj nws tus kheej qhov tseem ceeb thiab yuav tsum tau xaiv kom tsim nyog raws li kev ua haujlwm tiag tiag.

Yog tias koj xav tau kom nkag siab ntxiv txog cov txheej txheem xaiv thiab cov txheej txheem tsis zoo ntawm -voltage switchgear, lub nplhaib lub ntsiab thiab lub hauv paus txee, thov koj xav tiv tauj peb txhua lub sijhawm. Peb yuav muab koj nrog kev ua tiavHluav taws xob system txeeconfiguration cov lus qhia thiab kev txhawb nqa.
