Lub Tshuab Hluav Taws Xob Txawj Ntse Universal CJW1 (ACB)
Kev faib tawm
- Raws li qhov mounting: tsau thiab kos tawm
- Raws li cov ncej: peb ncej, plaub ncej
- Raws li txoj kev ua haujlwm: lub cev muaj zog thiab phau ntawv (txij nkawm thiab kho)
- Raws li qhov kev tso tawm: ntse dhau qhov kev tswj hwm tam sim no, qis-voltage instantaneous (lossis qeeb) tso tawm, thiab shunt tso tawm
- Lub peev xwm ntawm lub ntse over-current maub los:
- Kev faib tawm: H hom (ib txwm), M hom (ntse ib txwm), L hom (kev lag luam)
- muaj kev ua haujlwm ntawm kev tshaj tawm ntev ncua sijhawm rov qab tiv thaiv lub sijhawm txwv
- ib theem earthed tiv thaiv kev ua haujlwm
- Kev ua haujlwm qhia: teeb tsa qhov qhia tam sim no, kev ua haujlwm qhia tam sim no, txhua qhov hluav taws xob qhia (yuav tsum hais thaum koj txiav txim).
- Lub tswb ceeb toom muaj nuj nqi

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.
