Muaj ntau ntau hom kev faib khoom hauv cov khoom siv hluav taws xob hauv tsev thiab cov khoom xa tawm, txhua tus muaj cov txheej txheem sib txawv thiab cov txheej txheem kev ua haujlwm. Vim yog cov hauv qab no, cov qauv tsim ua tiav feem ntau yuav tsum tau hloov kho, lossis txawm tias rov tsim dua tshiab. Qhov no tsis tsuas yog cuam tshuam rau kev tsim kho lub sijhawm ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, tab sis kuj tsim teeb meem rau cov chaw tsim khoom lag luam hauv kev ua tiav cov khoom raws sij hawm thiab ua kom zoo.
Cov xwm txheej cuam tshuam rau kev hloov pauv rau kev tsim cov duab kos tiav yog raws li hauv qab no:
1. Cov chaw tsim khoom faib khoom pom zoo cov khoom uas lawv tsim tawm uas tej zaum yuav tsis haum rau cov neeg siv.
2. Cov koom haum tsim qauv tsis paub zoo txog qee qhov kev tsim cov txee tshiab thiab tsim qauv raws li cov neeg siv khoom xav tau.
3. Cov neeg siv tsis nkag siab txog lawv tus kheej cov kev xav tau thiab tsis tuaj yeem xaiv cov qauv txee raws li lawv cov kev xav tau tshwj xeeb.
Txhawm rau daws cov teeb meem saum toj no thiab ua tau raws li cov neeg siv cov kev xav tau kom raug xaiv ntau dua ntawm cov qauv kev faib khoom tshwj xeeb, cov yam ntxwv ntawm cov khoom siv hluav taws xob tsawg-voltage faib cov khoom hauv cov khoom siv hluav taws xob hauv tsev thiab cov tshuab xa tawm tau txheeb xyuas hauv qab no.
Cov qauv txee thiab cov txheej txheem tsis zoo ntawm cov khoom xa khoom xa tuaj uas tau hais los saum no tau txheeb xyuas hauv qab no.
Cov yam ntxwv tseem ceeb ntawm cov khoom lag luam tsim tawm hauv tsev yog tias cov qauv tshwj xeeb ntawm tib hom kev faib khoom tsim los ntawm cov tuam txhab tsim khoom hauv tsev tsis sib haum, thiab cov qauv tshwj xeeb ntawm cov khoom faib khoom kuj txawv. Cov khoom siv hluav taws xob tseem ceeb tau teeb tsa hauv cov khoom xa khoom tuaj yeem tuaj yeem tuaj yeem tau txais txiaj ntsig zoo -cov npe paub lossis cov npe hauv tsev.
Cov kev tsis sib haum xeeb tau piav qhia hauv qab no:
1. Qhov siab tshaj plaws tam sim no ntawm Main Busbar: Tus nqi ntsuas ntawm qhov siab tshaj plaws tam sim no uas lub ntsiab busbar nqa tau.
2. Rated Short-Lub Sijhawm Tsis Muaj Tam Sim No: Lub hauv paus txhais tau tias square tus nqi ntawm luv luv - lub sijhawm tiv taus tam sim no uas qee qhov Circuit Court hauv cov khoom ua tiav tuaj yeem nqa tau zoo raws li cov kev sim ntsuas tau teev tseg hauv 8.2.3 ntawm lub teb chaws tus qauv GB7251.1-2005, muab los ntawm cov chaw tsim khoom.
3. Peak Short-Lub Sijhawm Nrog Tam Sim No: Lub ncov tam sim no uas lub voj voog tuaj yeem ua tiav nyob rau hauv qhov kev sim ntsuas, raws li cov chaw tsim khoom tau teev tseg.
4. Kev Tiv Thaiv Kev Ruaj Ntseg: Cov qib kev tiv thaiv muab los ntawm cov cuab yeej ua tiav tiv thaiv kev sib cuag nrog cov khoom nyob, nrog rau kev nkag mus ntawm cov khoom txawv teb chaws thiab cov kua dej, raws li tus qauv IEC60529-1989. Rau cov kev ntsuam xyuas tshwj xeeb, thov xa mus rau IEC60529 tus qauv.
5. Internal Partitioning: Raws li IEC 60529-1989 tus qauv, los tiv thaiv tus kheej kev nyab xeeb, lub switchgear tau muab faib ua ob peb qhov chaw ywj pheej.
Cov kev tsis sib txawv ntawm cov qauv sib txawv ntawm cov khoom faib khoom sib txawv heev. Txawm hais tias cov txheej txheem ntawm cov khoom xa tawm tuaj txawv teb chaws feem ntau zoo dua rau cov khoom siv hauv tsev, nws tsis tuaj yeem xav tias cov khoom xa khoom tuaj txawv teb chaws yuav tsum zoo dua.
Raws li kev paub dhau los, cov ntsiab lus hauv qab no tau tham txog:
1. Cov khoom xa tuaj txawv teb chaws tau tsim thiab tsim tawm txawv teb chaws, feem ntau tsom rau lub ntiaj teb cov khoom siv hluav taws xob thiab kev lag luam. Vim tias cov kev xav tau thiab kev coj ua ntawm cov khoom siv hluav taws xob thiab kev faib khoom sib txawv ntawm lub teb chaws mus rau ib lub teb chaws, cov khoom xa tuaj txawv teb chaws yuav tsis haum rau kev lag luam hauv tsev.
2. Cov khoom siv hluav taws xob tseem ceeb uas siv rau hauv cov khoom xa tawm tuaj txawv teb chaws yog txhua yam khoom lag luam uas tuaj txawv teb chaws. Qee lub txee lub cev lossis cov khoom siv hauv txee yuav tsum raug xa mus, uas ua rau tus nqi siab dua rau cov khoom xa tawm txawv teb chaws piv rau cov khoom tsim hauv tsev.
3. Txawm hais tias cov kev tsis sib xws ntawm cov khoom xa tawm tuaj txawv teb chaws yog siab, feem ntau tsuas yog siv ib feem xwb, lossis txawm tsis muaj dab tsi. Piv txwv li, cov khoom xa tawm txawv teb tuaj yeem teeb tsa ntau lub voj voog hauv ib lub tsev ntau dua li cov khoom tsim tawm hauv tsev, tab sis qhov no ua tiav los ntawm kev txo cov peev txheej, uas feem ntau ua tsis tau raws li cov neeg siv khoom xav tau.
4. Txawm hais tias cov txheej txheem kev lag luam ntawm cov khoom siv hluav taws xob hauv tsev tau qis dua li cov khoom tuaj txawv teb chaws, lawv txaus rau feem ntau cov tshuab hluav taws xob hauv Suav teb.
5. Hais txog qhov zoo ntawm cov khoom faib khoom, tsuav yog cov tuam txhab ua raws li 3C cov cai rau kev tsim khoom thiab tshuaj xyuas, qhov zoo ntawm cov khoom xa tawm hauv tsev tsis tas yuav qis dua li cov khoom tuaj txawv teb chaws.
Hauv cov ntsiab lus, thaum xaiv ib lub txee faib khoom, cov ntsiab lus hauv qab no yuav tsum xav txog:
1. Nkag siab txog tus neeg siv cov kev xav tau thiab xaiv cov khoom tsim nyog tshaj plaws raws li qhov xwm txheej tiag tiag.
2. Ua ntej siv cov khoom tsim hauv tsev los ntawm cov tuam txhab paub zoo -. Tsis txhob ua qhov muag tsis pom kev xaiv cov khoom xa khoom xa tuaj nrog cov khoom siv siab dua, vim qhov no tuaj yeem ua rau cov khoom pov tseg.
3. Txij li cov hom ntawm cov khoom tseem ceeb siv nyob rau hauv cov khoom xa tawm txawv teb chaws yog zoo ib yam nrog lub txee lub cev, thaum xaiv cov khoom xa tawm txawv teb chaws, xyuam xim rau qhov tsis muaj ntawm cov khoom tseem ceeb; lawv yuav tsum ua kom tau raws li tus neeg siv xav tau.
