Cov lus piav qhia luv luv:

Cov lus fuses no yog haum rau cov cim nrog cov nqi ntsuas nrog ntsuas dc voltage txog 1500v thiab rated tam sim no txog 63a. Lawv tau txuas nrog hauv koob thiab sib txuas nrog photovoltaic panels thiab roj teeb kom muab cov tshuaj tiv thaiv luv luv rau kev them thiab hloov cov tshuab; Ib txhij, rau photovoltaic fais fab nroj tsuag, Combmerer inverter rectification tshuab, thiab luv-taws kev ua txhaum kev tiv thaiv; Thiab rau kev tiv thaiv ceev ceev ntawm surge tam sim no thiab luv-taws kev ua txhaum kev tiv thaiv hauv photovoltaic lub hwj chim hluav taws xob ntawm 20ka. Peb lub tuam txhab tam sim no ua cov kev ntsuam xyuas feem cuam tshuam ntxiv txhawm rau txhim kho qhov muaj peev xwm tawg ntawm cov khoom. Cov khoom ua raws li cov kev cai ntawm International Electrotechnical Commission Standrica tus qauv iec60269.
