Yuav ua li cas xaiv qhov zoo ntawm qhov tsawg voltage switchgear?

Tsawg voltage switchgear yog cov cuab yeej tseem ceeb hauv kev faib hluav taws xob, lub luag haujlwm rau kev faib, tswj, thiab tiv thaiv hluav taws xob hluav taws xob. Nrog ntau yam qauv muaj-GGD, GCK, GCS, MNS, ntau tus neeg siv tau tsis meej pem thaum xaiv tus qauv. Kab lus no txheeb xyuas cov qauv qauv, qhov sib txawv tseem ceeb, qhov zoo thiab qhov zoo los pab koj txiav txim siab paub.

Ⅰ. Kev faib tawm los ntawm Cov Qauv

Tsawg voltage switchgear feem ntau muab faib ua ob hom qauv:fixed homthiabrho tawm-hom.

Tsau hom Switchgear (Qauv: GGD)

Nyob rau hauv taag-type switchgear, Cheebtsam yog mus tas li mounted nyob rau hauv kev txhawb nqa. Circuits raug cais los ntawm kev faib tawm tab sis tsis tuaj yeem raug tshem tawm ua ib chav ua tiav.

Khoom nta:

GGD siv lub txee thoob ntiaj teb tsim nrog 8MF txias-khoov hlau ncej, ib nrab welded. Muaj 20-modulus mounting qhov, nrog siab coefficient ntawm universality.Cov naj npawb sib txawv ntawm cov cua kub dissipation qhov nyob rau sab sauv thiab qis kawg ntawm lub txee, kom lub kaw lus switchgear vaj huam sib luag tsim ib qho chaw cua cua los ntawm hauv qab mus txog rau lub hom phiaj ntawm tshav kub dissipation.Cov qauv kev tiv thaiv yog IP30, adjustable ntawm IP20 thiab IP40 nyob ntawm ib puag ncig xav tau.

Qhov txawv tseem ceeb:

Qhov tseem ceeb sib txawv ntawm rho tawm-hom yogkev saib xyuastxoj kev. Tsau-hom yuav tsum de-energizing lub txee los hloov cov khoom ntawm tus kheej, thaum tshem tawm-hom tso cai rau tag nrho cov haujlwm ua haujlwm tau hloov pauv sai.

Advantages thiabDyog qhov zoo:

Tej kev siv:Fais fab kev faib thiab teeb pom kev zoo nyob rau hauv substations, fais fab nroj tsuag, thiab industrial chaw. Rated tam sim no feem ntau 1000-3150A ntawm 380V.

Withdrawable-Hom Switchgear (Model: GCK, GCS, MNS)

Tshem tawm switchgear lub tsev ua haujlwm (breakers, contactors, instruments) raws li cov tub rau khoom tshem tau. Txhua tus tub rau khoom muaj peb txoj haujlwm: "txuas," "kev xeem," thiab "tshem tawm." Thaum lub voj voog ua haujlwm tsis zoo, lub tub rau khoom tuaj yeem hloov tau sai sai nrog qhov seem, txo qis qis qis.

Khoom nta:

Lub txee muab faib ua busbar compartment, apparatus compartment, thiab cable compartment, sib cais los ntawm steel los yog insulating barriers. Lub busbar compartment feem ntau yog nyob rau sab saum toj los yog nram qab, apparatus nyob rau hauv pem hauv ntej, thiab cable nkag nyob rau hauv lub rear. Mechanical interlocks ntawm lub qhov rooj tub rau khoom thiab lub qhov rooj tawg kom lub qhov rooj tsuas yog qhib thaum tus kov nyob rau hauv txoj hauj lwm tsis sib txuas.

Ⅱ. Kev sib piv ntawm Cov Qauv Nyiaj Them Tseem Ceeb

GCK, GCS, thiab MNS yog peb hom kev rho tawm ntau tshaj plaws. Kev nkag siab txog lawv qhov sib txawv yog qhov tseem ceeb.

GCK

Qhov chaw:Ib qho kev tsim tawm thaum ntxov hauv tsev, suav nrog Power Center (PC) thiab Lub Chaw Tswj Tsav Tsheb (MCC).

Qhov txawv tseem ceeb:Kab rov tav busbars mounted rau saum lub txee. Vertical busbars tsis muaj nplaim hluav taws-retardant yas ua haujlwm npog. Lub tshuab tub rau khoom yog yooj yim dua GCS thiab MNS.

Advantages thiabDyog qhov zoo:Muaj peev xwm tawg tau yooj yim, hloov hluav taws xob cov tswv yim, siab Circuit Court ceev ntawm ib lub txee, thiab txuag chaw. Txawm li cas los xij, cov khoom siv thav duab muaj lub zog tsis tshua muaj zog, cov txheej txheem kev ua haujlwm tsis tshua zoo, thiab nws tsis tuaj yeem cuam tshuam nrog lub tshuab computer.

GCS

Qhov chaw:Tsim nyob rau hauv nruab nrab-1990s raws li ABB's MNS platform, nrog rear-mounted lub ntsiab busbars. Nws ua haujlwm hloov kho tshiab rau GCK.

Qhov txawv tseem ceeb:Siv 20mm tub rau khoom module (MNS siv 25mm). Drawers muaj lub racking mechanism rau kev ua haujlwm smoother. Qhov tsawg kawg nkaus tub rau khoom loj yog 1/2 module; Qhov siab tshaj plaws circuits rau ib lub txee yog 22.

Advantages thiabDyog qhov zoo:Kev ntsuas kev ua haujlwm siab, siab tawg thiab ua kom muaj peev xwm, zoo dynamic thiab thermal stability, siab tiv thaiv kev ntsuas, thiab kev sib tw nrog cov khoom lag luam. Nco ntsoov tias yog tias cov kev sib txuas sib txuas tsis tau nruj, cov teeb meem xws li cua sov, eddy tam sim no, thiab loosening yuav tshwm sim.

MNS

Qhov chaw:Tsim nyob rau hauv kev hloov technology los ntawm ABB Switzerland. Siv 25mm modular C-profile thav duab thiab aluzinc-coated steel nyob rau hauv ib tug tag nrho cov qauv uas yuav tsum tau tsis muaj kev kho mob tom qab.

Qhov txawv tseem ceeb:Yuav ua tau los ntawm ob sab pem hauv ntej thiab nram qab. Qhov siab tshaj plaws ntawm ib lub txee ncav cuag 36 (siv 1/4 drawers). Cov tub rau khoom muaj xws li kev sib cuam tshuam cov txheej txheem, thaum GCS tsuas yog muaj kev cuam tshuam ntawm lub breaker nws tus kheej. Busbar layout zoo ib yam li GCS, tab sis tub rau khoom modularity thiab interlocking yog ntau refined.

Advantages thiabDyog qhov zoo:Compact tsim fits ntau functional units nyob rau hauv tsawg qhov chaw. Muaj zog structural versatility, hloov tau yooj yim los ua ke, thiab thoob ntiaj teb-theem kev ua tau zoo. Qhov kev txwv tseem ceeb yog tus nqi siab dua, uas yuav tsis haum rau cov neeg siv nyiaj me me thiab nruab nrab.

Ⅲ. Kev sib piv

Ⅳ. Cov lus pom zoo xaiv

Cov peev nyiaj-ua ntej, yooj yim Circuit Court yuav tsum→ XaivGGDfixed hom. Cov qauv kev paub tab, kev saib xyuas ncaj qha, tsim nyog rau kev faib khoom raws li qhov tsis muaj kev xav tau ntawm daim phiaj ntse.

Sib npaug ntawm tus nqi thiab kev ruaj ntseg→ XaivGCKlos yogGCS. GCK ua tau raws li cov kev xav tau yooj yim tshem tawm; GCS muaj kev txhim kho kev ua haujlwm thiab kev tiv thaiv busbar.

High automation, ntom circuits, computer system kev koom ua ke yuav tsum tau→ XaivMNS. Nws compact tsim thiab modularity yog zoo tagnrho rau high-sawv vaj tse, petrochemical systems, thiab lwm yam kev siv xav tau qhov chaw efficiency thiab txawj ntse.

Txawm hais tias xaiv lub txee xaiv, ib qho yuav tsum tau ua tib zoo saib seb cov chaw tsim khoom puas tau ua tiav hom kev xeem raws li IEC 60439-1 lossis GB 7251 tus qauv, kom ntseeg tau tias lub voj voog luv luv tiv taus lub zog, qhov kub thiab txias txwv thiab kev ua haujlwm rwb thaiv tsev ua tau raws li qhov yuav tsum tau ua. Kev tiv thaiv qib ntawm lub txee lub cev, kev tsim cov cua sov dissipation thiab kev cia siab hauv av yuav tsum tsis txhob raug ignored.

Sib piv sib txawv low voltage switchgear hom, cov qauv, qhov zoo thiab qhov tsis zoo. Tau txais cov lus qhia xaiv cov tswv yim rau koj qhov project faib hluav taws xob.
