2. Cov ntsiab lus ntawm cov khoom

YEW1 series Air Circuit Breaker (txij no mus hu ua circuit breaker) siv rau hauv kev faib khoom network nrog AC 50HZ, rated voltage 690V (lossis qis dua), thiab rated tam sim no 200A-6300A. Nws yog siv los faib hluav taws xob, tiv thaiv circuit thiab fais fab mov los ntawm kev puas tsuaj ntawm qhov tsis xws luag, xws li overload, under voltage, luv circuit, single-phase grounding. Circuit breaker muaj kev tiv thaiv ntse, thiab nws cov kev tiv thaiv xaiv yog qhov tseeb. Dhau li ntawm qhov ntawd, nws tuaj yeem txhim kho kev ntseeg siab ntawm lub zog muab hluav taws xob thiab zam kev tsaus ntuj tsis tsim nyog. Tib lub sijhawm, nws muaj qhov qhib-hom kev sib txuas lus interface kom paub txog plaub-chaw taws teeb ua haujlwm, uas yog kev tswj chaw taws teeb, chaw taws teeb tswj, kev ntsuas chaw taws teeb thiab kev sib txuas lus chaw taws teeb, txhawm rau ua kom tau raws li qhov xav tau ntawm chaw tswj hwm thiab lub kaw lus tsis siv neeg. Lub circuit breaker no muaj kev ua haujlwm cais tawm.

Faib pawg:

1. Ua raws li kev teeb tsa: Kho hom, Tub rau khoom hom.
2. Ua raws li tus ncej: 3P, 4P
3. Ua raws li kev ua haujlwm: Kev ua haujlwm hluav taws xob, Kev ua haujlwm tes (Kho, txij nkawm)

Tso Tawm:

Kev tswj hwm kev txawj ntse, tso tawm tam sim ntawd (lossis qeeb), tso tawm shunt.

3. Kev txawj ntse tswj kev ua haujlwm

1. kev tswj hwm kev txawj ntse: H (hom kev txawj ntse), M (hom txheem), L (hom kev lag luam)
2. Muaj kev txwv sijhawm ntev dhau, lub sijhawm luv luv, lub sijhawm tas mus li thiab kev ua haujlwm tam sim ntawd, nws tuaj yeem raws li tus neeg siv xav tau teeb tsa kev tiv thaiv.
3. Ib qho kev tiv thaiv hauv av.
4. Zaub muaj nuj nqi: teem tam sim no zaub, ua tam sim no zaub thiab txhua kab voltage tseem ceeb zaub (voltage zaub xav tau nug peb thaum muab kuv qhov kev txiav txim)
5. Lub tswb ceeb toom: overload tswb.
6. Kev ua haujlwm ntawm tus kheej: kev sim tus kheej kub dhau, kev kuaj mob microcomputer.
7. Kev ua haujlwm sim: tus tswj hwm ntse ntawm kev ua haujlwm.

4. Kev siv thiab kev teeb tsa ib txwm muaj

1. Qhov kub ntawm huab cua ib puag ncig: tus nqi siab tshaj plaws tsis pub tshaj + 40 ℃, tus nqi qis tshaj plaws tsis pub tshaj -5 ℃, tus nqi nruab nrab tsis pub tshaj + 35 ℃. Xav tau kev txiav txim tshwj xeeb.
2. Nruab qhov chaw nyob ntawm qhov siab tsis pub tshaj 2000m.
3. Cov huab cua: Cov av noo ntawm huab cua tsis pub tshaj 50% thaum huab cua ib puag ncig yog + 40 ℃, nws tuaj yeem muaj cov av noo ntau dua hauv qhov kub qis dua, qhov nruab nrab ntawm cov av noo siab tshaj plaws yog 90% hauv lub hli ntub dej siab tshaj plaws, lub hlis no qhov nruab nrab ntawm qhov kub siab tshaj plaws yog + 25 ℃ tib lub sijhawm, nws yuav tsum xav txog qhov dej noo ntawm cov khoom nto uas yuav ua rau muaj kev hloov pauv ntawm qhov kub thiab txias. Nws yuav tsum sab laj nrog kuv lub tuam txhab thaum nws tshaj qhov yuav tsum tau tswj hwm.
4. Qib kev tiv thaiv: IP30.
5 Chav Kawm ntawm kev ua qias tuaj: 3 chav kawm.
6. Siv cov chav kawm: B chav kawm lossis A chav kawm.
7. Pawg teeb tsa: Qhov ntsuas hluav taws xob ua haujlwm 660V (690V) thiab qis dua cov hluav taws xob Circuit Court breakers thiab undervoltage demerters, lub zog transformer thawj kauj ntawm pawg teeb tsa yog Ⅳ, lwm lub voj voog pabcuam, pawg teeb tsa tswj hwm yog Ⅲ.
8. Kev teeb tsa: Lub tshuab hluav taws xob xav tau raws li cov lus qhia no yuav tsum tau teeb tsa, lub tshuab hluav taws xob ntawm qhov ntsug gradient tsis pub tshaj 5 ° (lub tshuab hluav taws xob ntawm qhov ntsug gradient tsis pub tshaj 15 °)
