Yuav tsum tau qhov tsawg voltage disconnector lag tom qab qhov tsawg voltage Circuit Court breaker?

Puas muaj qhov kev pom zoo li no tias lub disconnector yog qib qis, thiab lub Circuit Court breaker yog qib siab, qhov twg cov disconnector siv, lub Circuit Court breaker tuaj yeem hloov tau?Lub tswv yim no yog debatable, tab sis disconnectors thiab Circuit Court breakers muaj lawv tus kheej daim ntawv thov.

Tsawg voltage Circuit Court breaker yog ib qho khoom siv hluav taws xob hloov hluav taws xob uas tuaj yeem ua, nqa, thiab tawg tam sim no nyob rau hauv cov xwm txheej hauv Circuit Court, thiab tseem tuaj yeem ua, nqa, thiab ua txhaum tam sim no rau qee lub sijhawm nyob rau hauv cov xwm txheej txawv txav xws li luv luv Circuit Court.Cov hluav taws xob hluav taws xob tsawg tsawg tuaj yeem muab faib ua cov kab hluav taws xob hluav taws xob (ACB), molded case circuit breakers (MCCB) thiab micro circuit breakers (MCB).Qhov hluav taws xob tsis tshua muaj hluav taws xob hloov hluav taws xob muaj lub luag haujlwm ntawm kev rho tawm thiab hloov.Ua ntej ntawm tag nrho cov, nws muaj qhov kev cais tawm.Nyob rau tib lub sijhawm, nws tuaj yeem txuas nrog, tiv taus thiab rhuav tshem cov load tam sim no raws li qhov xwm txheej ib txwm muaj.Uas yog hais tias, lub isolator hloov muaj kev ua haujlwm ntawm ob qho tib si cais thiab hloov.

Lub luag haujlwm ntawm lub tshuab cais tawm yog txiav tawm lub zog ntawm cov kab hluav taws xob lossis cov khoom siv hluav taws xob.Nyob rau tib lub sijhawm, koj tuaj yeem pom qhov pom tseeb disconnect point.Lub tshuab cais tawm tsis tuaj yeem tiv thaiv kab lossis khoom siv.Tab sis qhov hloov pauv tsis tas yuav muaj kev sib cais ua haujlwm, nws muaj kev ua haujlwm ntawm kev hloov mus rau thiab tawm ntawm cov khoom thauj tam sim no, tuaj yeem tiv taus qee lub sijhawm ntawm luv luv Circuit Court tam sim no.Piv txwv li, lub tshuab hluav taws xob semiconductor tsis tuaj yeem siv los ua ib qho kev sib cais, vim tias cov khoom siv hluav taws xob semiconductor tsis raug cais tawm ntawm lub cev, dhau qhov kev xav tau ntawm cov xau tam sim no ntawm cov isolator tsawg dua 0.5mA, yog li cov khoom siv hluav taws xob semiconductor yuav tsum tsis txhob siv los ua cov khoom siv hluav taws xob. cais tawm.

Qhov tseeb, muaj ntau daim ntawv thov ntawm kev hloov pauv hloov pauv, tab sis qee qhov chaw, kev siv lub tshuab cais tawm hloov pauv los ntawm kev hloov hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv pej xeem kev lag luam, uas tsis tsuas yog tsis tsim thiab tsim kho raws li qhov yuav tsum tau ua. cov specification, tab sis kuj nce tus nqi ntawm qhov project.Cov kev siv ntawm disconnecting hloov yog raws li nram no:

(1) Sab saum toj lub ntsiab faib txee yog tiv thaiv los ntawm Circuit Court breakers los yog fuses, thiab cov hluav taws xob hom fais fab mov hom yog saws mus rau hauv tsev.Tsis muaj ceg nyob hauv nruab nrab ntawm txoj kab hluav taws xob.Lub cable inlet hloov mus rau lub txee faib khoom yuav tsum tau cais tawm.

(2) Cov khoom siv sib cais yuav tsum tau teem rau ntawm lub ntsiab Circuit Court ntawm ob txoj kab hluav taws xob inlet ntawm ob lub tshuab hluav taws xob txiav, thiab cov khoom siv cais tshwj xeeb yuav tsum tau siv.

(3) seb qhov hluav taws xob tsis tshua muaj hluav taws xob xa hluav taws xob puas yuav tsum tau teeb tsa tshwj xeeb xav tau kev tshuaj xyuas tshwj xeeb, yog tias qhov hluav taws xob tsis tshua muaj hluav taws xob faib hluav taws xob yog lub txee ntawm cov tub rau khoom, koj tsis tuaj yeem teeb tsa cov khoom siv cais tawm, vim tias lub txee ntawm cov tub rau khoom tuaj yeem yog lub voj voog. breaker thiab lwm yam tag nrho tawm;Yog hais tias qhov hluav taws xob tsis tshua muaj hluav taws xob faib txee yog lub txee ruaj khov, yuav tsum tau siv lub tshuab hluav taws xob disconnecting los yog ib lub tshuab hluav taws xob uas muaj kev sib cais yuav tsum tau siv.

(4) Tag nrho cov kab tuaj ntawm lub thawv cable yuav tsum tau txais kev hloov pauv tshwj xeeb, thiab txhua lub ceg hluav taws xob yuav tsum tau txais ib lub fuse hom disconnecting hloov lossis MCCB nrog kev ua tiav kev sib cais.

Hauv luv luv, txhawm rau pab txhawb kev saib xyuas, kuaj thiab kho dua tshiab ntawm cov kab hluav taws xob lossis cov khoom siv hluav taws xob, nws yog ib qho tseem ceeb uas yuav tsum tau nruab ib lub disconnecting mus rau hauv qhov chaw uas yooj yim rau kev khiav lag luam thiab yooj yim rau kev soj ntsuam.
