Ib puag ncig xwm txheej rau kev ua haujlwm thiab kev teeb tsa
- ambient kub: -5 ℃ ~ 40 ℃, thiab nruab nrab kub hauv 24 teev hauv qab +35 ℃ (tshwj tsis yog rau kev txiav txim tshwj xeeb).
- Qhov siab ntawm qhov chaw teeb tsa: ≤2000m.
- Tus txheeb ze av noo: Tsis pub tshaj 50% ntawm nws qhov siab tshaj plaws ambient kub ntawm +40 ℃.Nrog rau qhov ntsuas kub qis dua, cov av noo siab dua yuav raug tso cai, tab sis qhov nruab nrab qhov nruab nrab qis tshaj plaws nyob rau hauv ib lub montn tsis tshaj +25 ℃ thaum lub hli ntub dej ntau, thiab qhov siab tshaj plaws txhua hli nruab nrab cov txheeb ze tsis tshaj 90% hauv lub hli, thiab muab kev saib xyuas rau cov lwg. ntawm cov khoom nto, uas yuav tshwm sim vim qhov kub hloov pauv.
- Kev tiv thaiv kev ua qias tuaj: 3 degree.
- Txhim kho pawg: Ⅳ rau breaker lub ntsiab circuits, coils ntawm nyob rau hauv voltage tso tawm thiab thawj Circuit Court ntawm transformers;Ⅲ rau lwm lub koom haum pab cuam thiab tswj Circuit Court.
- Cov breakers siv nyob rau hauv cov nkoj thiab nyob rau hauv cov huab cua sov cheeb tsam tuaj yeem ua haujlwm ib txwm tsis muaj kev cuam tshuam ntawm huab cua ntub, ntsev pos huab thiab mildew.
- Cov breakers siv hauv nkoj tuaj yeem ua haujlwm tau zoo raws li kev vibration.
- Lub breaker yuav tsum tau ntsia raws li cov cai hauv kev ua haujlwm phau ntawv.Rau cov kev sib tsoo hauv kev siv ntau, qhov ntsug gradient tsis ntau tshaj 50, rau qhov uas siv rau hauv nkoj, qhov ntsug gradient tsis ntau tshaj 22.50.
- Lub breaker yuav tsum tau muab tso rau hauv qhov chaw uas tsis muaj qhov nruab nrab tawg thiab cov khoom siv hluav taws xob thiab tsis muaj roj, uas yuav ua rau cov hlau tsis zoo los yog rhuav tshem cov rwb thaiv tsev.
- Lub breaker yuav tsum tau muab tso rau hauv qhov chaw ntawm lub switchboard thiab lub qhov rooj yuav tsum tau kho ntxiv, kev tiv thaiv qib yog mus txog lP40.
