Qhov txawv ntawm molded case Circuit breaker thiab cua hloov, yuav ua li cas xaiv cov cua hloov tsim nyog?

Tsawg-voltage Circuit Court breaker tuaj yeem muab faib ua" low-pressure molded case circuit breaker" thiab" low-voltage thav duab Circuit Court breaker", yav dhau los rau qis-voltage me tam sim no, tom kawg rau qis-voltage loj tam sim no, qhov tsawg-siab molded rooj plaub Circuit Court breaker feem ntau hu ua" tsis siv neeg cua hloov".

Qhov sib txawv tseem ceeb ntawm huab cua qhib thiab cov ntaub ntawv yas:

1, molded case Circuit Court breaker kuj yog" cua Circuit Court breaker". Feem ntau siv cua Circuit Court breakers yog thav duab Circuit Court breakers thiab molded rooj plaub Circuit Court breakers.Cov qub muaj peev xwm loj, loj rated tawg tam sim no thiab loj ntim. , yog li tsis muaj cov ntaub ntawv yas, thiab cov khoom ntawm lub breaker yog mounted ntawm ib tug steel thav duab.Qhov tom kawg yog lub peev xwm me me, rated breaking tam sim no kuj me me, yog li lub ntim me me, tag nrho Circuit Court breaker yog tiv thaiv los ntawm yas. case.General thav duab Circuit Court breakers yog siv rau lub hwj chim circuits nrog siab tam sim no, thaum molded case Circuit Court breakers yog siv rau load circuits.

2, cua hloov hauv me me tam sim no feem ntau ua lub luag haujlwm ntawm" cais" thiab" tiv thaiv ntaus ntawv", kuj hu ua tsis siv neeg hloov, kuj hu ua cua Circuit Court breaker;

3, Circuit Court breaker muaj lub peev xwm zoo tua arc, nyob rau hauv cov ntaub ntawv ntawm luv luv Circuit Court thiab loj tam sim no, tsis siv neeg mus txawv tebchaws; Nyob rau hauv lub high voltage, high tam sim no Circuit Court, feem ntau siv rau hluav taws xob hluav taws xob, hluav taws xob, hloov, disconnect load khiav hauj lwm cov khoom siv hluav taws xob. ;

4, qib tam sim no: yas rooj plaub Circuit Court breaker feem ntau yog 630A hauv qab no, cua Circuit Court breaker feem ntau yog 630A saum toj no, micro circuit breaker feem ntau yog 63A hauv qab no;

5, qhov sib txawv ntawm qhov voltage: qhov dav dav cua hloov siv qhov hluav taws xob qis dua 500V, thiab cov hluav taws xob hluav taws xob feem ntau tuaj yeem siv ntau dua 220V ntawm qib voltage;

6, lub peev xwm ntawm qhov tam sim no sib txawv: lub tshuab hluav taws xob dav dav tuaj yeem tiv taus lub nra thiab luv Circuit Court tam sim no loj dua;

7, qhov sib txawv ntawm arcing nruab nrab thiab hom: arcing nruab nrab thiab hom ntawm Circuit Court breaker tsis tsuas yog muaj cua Circuit Court breaker, tab sis kuj lub tshuab nqus tsev Circuit Court breaker, ntau roj Circuit Court breaker, tsawg roj Circuit Court breaker, sulfur hexafluoride Circuit Court breaker, thiab lwm yam.

8, qhov sib txawv ntawm cov cuab yeej txhawb nqa: feem ntau hais lus, kev ntsuas ntawm Circuit Court breaker yog txheeb ze rau qhov hloov pauv huab cua, thiab cov cuab yeej txhawb nqa ntawm cov kev xav tau thiab cov thawj coj ua haujlwm yog qhov nyuaj dua.

Circuit Court breaker lub tshuab nqus tsev Circuit Court breaker thiab SF6 Circuit Court breaker thiab lwm yam qauv, nws tawg tam sim no loj tshaj qhov zoo tib yam cua hloov, lub peev xwm tawg kuj loj dua, lub tshuab nqus tsev Circuit Court breaker feem ntau yog siv rau 6KV system, SF6 Circuit Court breaker rau 500KV substation, ob leeg nrog DC 110V raws li kev tswj fais fab mov, tshwm sim los ntawm kev tswj lub teeb liab yuav ua, Qhov dav dav cua hloov siv nyob rau hauv 380/220 system, sib npaug rau riam hloov.

Cua qhib kev xaiv:

1, thawj yog lub ntsiab nres: koj tuaj yeem siv 25-40A, uas yog xam raws li lub zog siab tshaj plaws ntawm tsev neeg.Qhov no lub zog yuav tsum xav txog ob peb yam khoom siv hluav taws xob ntxiv tom qab, yog tias tsis xav txog, qhov yuav muaj peev xwm tshaj li teev. tam sim no vim load, nquag mus ncig.Tag nrho nres=siab tshaj fais fab / 220V.

2. Yog hais tias lub zog siab tshaj plaws ntawm tsev neeg yog 8000W, tag nrho cov nres=8000/220=36.4A.Kev siv ntau yam specifications 10, 16, 20, 25, 32, 40, 63A, nyob rau hauv lub luv luv Circuit Court breaker zaub raws li C10, C16, C20, C25, C32, C40, C63, koj yuav tsum xaiv 40A 2P (bipolar, xoom nyob hlau ob lub luv luv) luv-circuit raws li lub ntsiab nres.Txhua ceg muaj tej yam kev mob xaiv 1P leakage protector, tsis muaj teeb pom kev zoo tuaj yeem xaiv 1P Circuit Court breaker.Dej rhaub, cua txias, precision khoom, khoom siv hauv chav ua noj, teeb pom kev zoo, ib txoj kev.Hop pem teb tuaj yeem muab faib los ntawm kev faib hauv pem teb.

3, teeb pom kev zoo feem ntau xaiv 10A, cua txias thiab lub rhaub dej tuaj yeem siv 16-25A raws li lub zog, qhov tsim nyog amplification point, tsis txhob pib lub sijhawm tam sim no loj dhau thiab mus ncig.Precision khoom 20A, cov khoom siv hauv chav ua noj 20-25A.

Nco tseg:

1. Qhov ntsuas tam sim no ntawm kev hloov pauv huab cua yog txiav txim siab los ntawm kev suav tam sim no ntawm kab.

2. Qhov luv luv-circuit teeb tam sim no ntawm cov cua hloov yuav tsum zam qhov kev ua haujlwm pib tam sim no ntawm txoj kab.

3. Tshawb xyuas lub peev xwm tawg ntawm huab cua hloov raws li qhov siab tshaj plaws luv-circuit tam sim no ntawm cov kab.

4, raws li qhov tsawg kawg nkaus luv luv tam sim no ntawm kab los xyuas qhov rhiab heev ntawm kev hloov pauv huab cua, uas yog, qhov tsawg kawg nkaus tam sim no ntawm txoj kab yuav tsum tsis pub tsawg dua 1.3 npaug ntawm qhov hloov pauv huab cua luv luv. tam sim no.

5, raws li qhov cuam tshuam luv luv tam sim no ntawm txoj kab (piv txwv li qhov siab tshaj plaws tam sim no tus nqi luv luv tam sim no) txhawm rau txheeb xyuas qhov ntsuas luv luv-circuit txuas lub peev xwm ntawm cov cua hloov (qhov siab tshaj qhov xav tau siab tshaj tam sim no), uas yog, yav tom ntej yuav tsum loj dua qhov qub.
