Kev ua haujlwm ntawm DC Circuit Breakers

1. Qhov siab ntawm qhov chaw teeb tsa tsis pub tshaj 2000m;

2. Qhov kub ntawm huab cua tsis siab tshaj 40 degree thiab tsis qis dua -5 degree; thiab 24-teev tus nqi nruab nrab tsis pub tshaj 35 degree (tshwj tsis yog rau kev txiav txim tshwj xeeb).

3. Qhov txheeb ze av noo ntawm huab cua ntawm qhov chaw teeb tsa. Qhov kub siab tshaj plaws yog tsis ntau tshaj 50 feem pua ​​​​ntawm qhov ntxiv 40 degree, thiab cov av noo siab dua tau tso cai rau qhov kub qis dua, piv txwv li, txog li 90 feem pua ​​​​ntawm 2O degree. Kev ntsuas tshwj xeeb yuav tsum tau ua rau qee zaus condensation tshwm sim los ntawm kev hloov kub qhuav.

4. Tsis muaj qhov cuam tshuam loj heev nyob rau hauv cov huab cua, thiab tsis muaj qhov chaw uas tsis muaj cov pa roj thiab cov hmoov av conductive uas tuaj yeem ua rau cov hlau tsis zoo thiab ua rau cov rwb thaiv tsev puas.

5. Ib qho chaw tsis muaj nag thiab daus.

6. Cov pa phem yog qib 3.

7. Installation category: The installation category of the main circuit of the circuit breaker is Ⅲ, and the installation category of auxiliary circuits and control circuits that are not connected to the main circuit is Ⅱ.
