7. Lub Circuit Court breaker yog ntsia rau hauv lub txee, tiv thaiv qib yog IP40;Yog tias ntxiv qhov rooj ncej, qib kev tiv thaiv tuaj yeem ncav cuag IP54
Kev faib tawm
1. Lub Circuit Court breaker muab faib ua peb ncej thiab plaub ncej raws li tus naj npawb ntawm ncej.
2. Qhov ntsuas tam sim no ntawm Circuit Court breaker yog muab faib ua 1600A, 2000A, 3200A, 4000A, 5000A (muaj peev xwm nce mus rau 6300A).
3. Circuit Court breakers raug faib raws li lub hom phiaj: kev faib hluav taws xob, kev tiv thaiv lub cev muaj zog, kev tiv thaiv lub tshuab hluav taws xob.
4. Raws li kev ua haujlwm hom:
Lub cev muaj zog ua haujlwm;
Kev tuav haujlwm (rau kev kho dua tshiab thiab kho).
5. Raws li kev teeb tsa hom:
Kho hom: kab rov tav kev sib txuas, yog tias ntxiv cov tsheb npav ntsug, tus nqi tsheb npav ntsug yuav yog
xam cais;
hom kos tawm: kab rov tav kev sib txuas, yog tias ntxiv cov tsheb npav ntsug, tus nqi ntawm cov tsheb npav ntsug yuav raug xam cais.
6. Raws li hom tripping tso tawm:
Kev txawj ntse tshaj qhov kev tso tawm tam sim no, Hauv-voltage instantaneous (los yog ncua) tso tawm
thiab Shunt tso tawm
7. Raws li hom kev txawj ntse tswj:
M hom (hom ntse ntse);
H hom (kev sib txuas lus ntse hom).
Cov yam ntxwv ua haujlwm ntawm ntau hom kev txawj ntse tswj
M hom: Ntxiv rau plaub ntu kev tiv thaiv cov yam ntxwv ntawm kev thauj khoom ntev ntev, luv luv Circuit Court ncua sij hawm ncua, instantaneous thiab lub ntiaj teb to, nws kuj muaj qhov txhaum cai qhia, txhaum cov ntaub ntawv, kuaj muaj nuj nqi, ammeter zaub, voltmeter zaub, ntau yam tswb ceeb toom tso zis, thiab lwm yam Nws muaj ntau yam kev tiv thaiv tus yam ntxwv ntawm thaj chaw muaj txiaj ntsig thiab ua tiav cov haujlwm pabcuam.Nws yog hom multi-functional thiab tuaj yeem siv rau feem ntau cov ntawv thov kev lag luam nrog cov kev xav tau siab.
H hom: Nws tuaj yeem muaj tag nrho cov haujlwm ntawm M hom.Nyob rau tib lub sijhawm, hom kev tswj hwm no tuaj yeem paub txog "plaub qhov chaw taws teeb" ua haujlwm ntawm telemetry, kev hloov pauv chaw taws teeb, tswj chaw taws teeb thiab chaw taws teeb teeb liab los ntawm daim npav network lossis interface converter.Nws yog qhov tsim nyog rau lub network system thiab tuaj yeem raug saib xyuas hauv nruab nrab thiab tswj los ntawm lub khoos phis tawj sab saud.
1. Ammeter muaj nuj nqi
Tam sim no ntawm lub ntsiab Circuit Court tuaj yeem tshwm sim ntawm qhov screen.Thaum xaiv tus yuam sij raug nias, tam sim no ntawm theem nyob rau hauv qhov taw qhia teeb nyob rau hauv los yog lub siab tshaj plaws theem tam sim no yuav tshwm sim.Yog tias tus yuam sij xaiv raug nias dua, tam sim no ntawm lwm theem yuav tshwm sim.
2. Kev kuaj mob tus kheej muaj nuj nqi
Chav tsev mus txawv tebchaws muaj kev ua haujlwm ntawm kev kuaj mob hauv zos.Thaum lub khoos phis tawj tawg, nws tuaj yeem xa tawm qhov yuam kev "E" zaub lossis lub tswb, thiab rov pib lub khoos phis tawj tib lub sijhawm, tus neeg siv kuj tuaj yeem cuam tshuam lub Circuit Court breaker thaum xav tau.
Thaum qhov ntsuas kub hauv cheeb tsam mus txog 80 ℃ lossis qhov kub hauv lub txee siab tshaj 80 ℃ vim qhov cua sov ntawm kev sib cuag, lub tswb tuaj yeem tawm thiab lub tshuab hluav taws xob tuaj yeem qhib ntawm qhov me me tam sim no (thaum tus neeg siv xav tau)
3. Kev teeb tsa muaj nuj nqi
Nias qhov ncua sij hawm ntev, ncua sij hawm luv luv, instantaneous, grounding teeb tsa ua haujlwm yuam sij thiab +, - tus yuam sij los teeb tsa lub sijhawm tam sim no thiab ncua sij hawm arbitrarily raws li tus neeg siv yuav tsum tau, thiab nias lub cim cia tom qab qhov xav tau tam sim no lossis ncua sij hawm mus txog.Yog xav paub ntxiv, saib tshooj ntawm kev teeb tsa, siv thiab tu.Kev teeb tsa ntawm chav tsev mus txawv tebchaws tuaj yeem nres ua haujlwm tam sim no thaum muaj kev cuam tshuam overcurrent tshwm sim.
4. Kev sim ua haujlwm
Nias lub teeb qhov tseem ceeb los ua tus nqi tam sim no kom ncua sij hawm ntev, ncua sij hawm luv luv, lub xeev tam sim no, qhov taw qhia lub plhaub thiab +,- qhov tseem ceeb, xaiv tus nqi tam sim no, thiab tom qab ntawd nias qhov ntsuas qhov ntsuas kom ua tiav qhov kev tso tawm.Muaj ob hom kev xeem yuam sij; ib qho yog qhov tsis yog-tripping qhov tseem ceeb, thiab lwm qhov yog tripping xeem yuam sij.Yog xav paub meej, saib cov khoom siv tripping hauv tshooj ntawm Kev Txhim Kho, Siv thiab Kho.Cov kev xeem dhau los tuaj yeem ua tau thaum lub tshuab hluav taws xob txuas nrog rau daim phiaj hluav taws xob.
Thaum ib qho overcurrent tshwm sim hauv lub network, qhov kev sim ua haujlwm tuaj yeem cuam tshuam thiab kev tiv thaiv overcurrent tuaj yeem ua tau.
5. Load saib xyuas muaj nuj nqi
Teem ob qhov teeb tsa qhov tseem ceeb, Ic1 teeb tsa ntau yam (0.2 ~ 1) Hauv, Ic2 teeb tsa ntau yam (0.2 ~ 1) Hauv, Ic1 ncua tus yam ntxwv yog qhov cuam tshuam lub sijhawm txwv tus yam ntxwv, nws qhov kev ncua sij hawm yog 1/2 ntawm qhov ncua sij hawm ncua sij hawm.Muaj ob hom kev ncua sij hawm ntawm Ic2: thawj hom yog qhov hloov pauv lub sijhawm txwv tus yam ntxwv, lub sijhawm teeb tsa tus nqi yog 1/4 ntawm qhov ncua sijhawm ncua sijhawm;hom thib ob yog lub sijhawm txwv tus yam ntxwv, lub sijhawm ncua sijhawm yog 60s.Cov qub yog siv los txiav tawm qhov tseem ceeb tshaj plaws ntawm cov theem qis thaum qhov tam sim no nyob ze rau qhov kev teeb tsa overload, tom kawg yog siv los txiav tawm qhov tsis tseem ceeb ntawm cov theem qis thaum tam sim no tshaj tus nqi ntawm Ic1, tom qab ntawd tam sim no poob los ua kom lub ntsiab circuits thiab tseem ceeb load circuits tseem powered.Thaum tam sim no poob rau Ic2, ib qho kev hais kom ua tom qab ncua sij hawm, thiab lub voj voog uas tau raug txiav tawm los ntawm theem qis dua rov qab los rov qab kho lub zog ntawm tag nrho cov kab ke, thiab kev saib xyuas lub luag haujlwm.
6. Zaub muaj nuj nqi ntawm lub tripping unit
Lub tripping unit tuaj yeem tso saib nws qhov kev khiav hauj lwm tam sim no (xws li ammeter muaj nuj nqi) thaum lub sijhawm ua haujlwm, qhia cov ntu uas tau teev tseg los ntawm nws cov yam ntxwv tiv thaiv thaum muaj teeb meem tshwm sim, thiab kaw qhov kev ua txhaum thiab qhov txhaum tam sim no tom qab tawg lub Circuit Court, thiab tso saib tam sim no, lub sijhawm thiab ntu. qeb ntawm qhov chaw seem ntawm lub sijhawm teeb tsa.Yog tias nws yog qhov kev txiav txim qeeb, qhov taw qhia lub teeb flashes thaum lub sijhawm ua haujlwm, thiab qhov taw qhia lub teeb hloov los ntawm flashing mus rau lub teeb tas li tom qab lub Circuit Court breaker raug txiav.
7.MCR on-off thiab analog tripping tiv thaiv
Tus maub los tuaj yeem nruab nrog MCR on-off thiab analog tripping tiv thaiv raws li tus neeg siv xav tau.Ob hom ob qho tib si yog kev ua tam sim ntawd.Lub teeb liab txhaum tam sim no xa cov lus qhia ncaj qha los ntawm kev sib piv kho vajtse.Qhov teeb tsa tam sim no tus nqi ntawm ob qhov kev ua yog txawv.Qhov teeb tsa tus nqi ntawm cov analog tripping yog siab, uas feem ntau yog tus nqi siab tshaj plaws ntawm kev tiv thaiv tam sim no tus nqi ntawm tus maub los (50ka75ka / 100kA), Tus maub los ua haujlwm txhua lub sijhawm thiab feem ntau siv los ua thaub qab.Txawm li cas los xij, qhov teeb tsa tus nqi ntawm MCR tsawg, feem ntau 10kA.Qhov kev ua haujlwm no tsuas yog ua haujlwm thaum lub tshuab hluav taws xob qhib, nws tsis ua haujlwm thaum lub sijhawm ua haujlwm kaw.Tus neeg siv tuaj yeem xav tau tus nqi tshwj xeeb nrog qhov tseeb ntawm ± 20%.
