Cov ntawv thov

CJW1 series cov cuab yeej hluav taws xob ntse thoob ntiaj teb siv tau los tswj lub network faib hluav taws xob qis thiab ua kom nws muaj kev nyab xeeb. Nws tau teeb tsa rau hauv cov vaj huam sib luag faib hluav taws xob qis, ua haujlwm ua tus hloov pauv tseem ceeb los ua lub luag haujlwm kev nyab xeeb dav dav. Nws cov yam ntxwv kev siv tshuab tau mus txog tus qauv thoob ntiaj teb ntawm cov khoom zoo li ntawd hauv xyoo 1990. Nws haum rau lub voj voog ntawm AC 50Hz, qhov ntsuas hluav taws xob yog 660V (690V) lossis qis dua, ntsuas tam sim no 400A-6300A.

Varied intelligent maub los muaj ntau yam haujlwm.

Cov breakers ua raws li qhov xav tau ntawm cov qauv hauv qab no, IEC 60947-2, GB14048.2-2001.

Ib puag ncig ntawm kev ua haujlwm thiab kev teeb tsa

Qhov kub thiab txias: -5 ℃ ~ 40 ℃, thiab qhov kub nruab nrab hauv 24 teev qis dua + 35 ℃ (tshwj tsis yog cov xaj tshwj xeeb).
Qhov siab ntawm qhov chaw teeb tsa: ≤2000m.
Qhov av noo: Tsis pub tshaj 50% ntawm qhov kub siab tshaj plaws ntawm +40 ℃. Yog tias qhov kub qis dua, qhov av noo siab dua yuav raug tso cai, tab sis qhov kub nruab nrab qis tshaj plaws hauv ib hlis tsis pub tshaj +25 ℃ thaum lub hli uas muaj av noo tshaj plaws, thiab qhov nruab nrab siab tshaj plaws txhua hli tsis pub tshaj 90% hauv lub hli ntawd, thiab xav txog cov dej noo ntawm qhov chaw ntawm cov khoom, uas yuav tshwm sim vim qhov kub hloov pauv.
Kev tiv thaiv kev ua qias tuaj: 3 degree.
Kev teeb tsa pawg: Ⅳ rau lub voj voog tseem ceeb ntawm lub breaker, cov kauj ntawm kev tso tawm qis zog thiab lub voj voog tseem ceeb ntawm cov transformers; Ⅲ rau lwm lub voj voog pabcuam thiab lub voj voog tswj.
Cov khoom siv hluav taws xob siv hauv nkoj thiab hauv thaj chaw kub thiab noo noo tuaj yeem ua haujlwm li qub yam tsis muaj kev cuam tshuam ntawm huab cua noo, ntsev pos huab thiab mildew.
Cov breakers siv hauv nkoj tuaj yeem ua haujlwm tau zoo nyob rau hauv kev co ib txwm muaj.
Lub breaker yuav tsum tau teeb tsa raws li cov lus qhia hauv phau ntawv qhia kev siv. Rau cov breakers uas siv ntau, qhov gradient ntsug tsis pub ntau tshaj 50, rau qhov uas siv rau ntawm nkoj, qhov gradient ntsug tsis pub ntau tshaj 22.50.
Lub breaker yuav tsum tau muab tso rau hauv qhov chaw uas tsis muaj cov khoom tawg thiab cov hmoov av conductive thiab tsis muaj roj, uas yuav corrode hlau lossis rhuav tshem cov rwb thaiv tsev.
Lub breaker yuav tsum tau ntsia rau hauv qhov chaw ntawm switchboard thiab doorframe yuav tsum tau kho ntxiv, qib kev tiv thaiv yog txog li lP40.
