4. Mounting condition
1) Ambient cua kub
1) Xav txog qhov ntsuas kub ntau dhau los txhawm rau txhawm rau txhawm rau kev laus ntawm cov khoom yas, qhov txwv sab saud tsis ntau tshaj +40 ℃.
Xav txog tias qhov kub siab tshaj ambient kub ntau dhau
hloov qhov haum ntawm cov txheej txheem cov tswv cuab, qhov qis qis feem ntau tsis qis dua -5 ℃.
Xav txog qhov kev pab cuam lub neej ntawm Circuit Court breaker, tus nqi nruab nrab ntawm 24 teev tsis ntau tshaj +35 ℃.
Nco tseg:
① Kev ua haujlwm ntawm tus nqi qis qis yog -10 ℃ lossis -25 ℃.Tus neeg siv yuav tsum tshaj tawm rau lub tuam txhab thaum xaj.
②Qhov kev ua haujlwm ntawm tus nqi qis tshaj qhov siab tshaj +40 ℃ lossis tus nqi qis qis qis dua -25 ℃, tus neeg siv yuav tsum sib tham nrog lub tuam txhab.
2) Kev teeb tsa qhov chaw
Qhov siab tsis tshaj 2000m;
Kev tiv thaiv Circuit Court;
Qhov taw qhia kev teeb tsa suav qhov luv luv tam sim no Ik tsis ntau tshaj 3000A;
Lub Circuit Court breaker yuav tsum tau ntsia raws li cov kev cai ntawm kev siv ntawm phau ntawv, ntsug inclination ntawm lub Circuit Court breaker yuav tsum tsis txhob ntau tshaj 5 °, Lub ib puag ncig kev co tsis ntau tshaj 5g.
3) Cov xwm txheej ntawm huab cua
Qhov txheeb ze av noo ntawm huab cua tsis tshaj 50% ntawm huab cua ambient kub +40 ° C. Nws tuaj yeem muaj cov txheeb ze cov av noo siab dua ntawm qhov kub thiab txias.Lub hli nruab nrab qhov siab tshaj plaws ntawm cov av noo ntawm lub hli ntub dej tshaj plaws yog 90%, thiab qhov nruab nrab qhov kub thiab txias rau lub hli yog +25 ° C thiab coj mus rau hauv tus account condensation ntawm cov khoom vim qhov kub thiab txias.
4) Cov pa phem
Cov pa phem yog theem 3.
5) Installation Qeb
Lub Circuit Court breaker tiv thaiv Circuit Court yog ntsia rau hauv qeb III.
6) Cov xaim hla ntu tau teeb tsa raws li qhov siab tshaj plaws cov cua sov tam sim no Ith ntawm Circuit Court breaker.
