Wodzipatula wa DC

123

Makina opangidwa mwaluso kwambiri m'chilengedwechi ndi thupi la munthu. Ili ndi njira yabwino kwambiri yodzitetezera komanso kudzikonza. Ngakhale makina anzeru kwambiri amafunikira kukonza ndi kukonza nthawi zina. Momwemonso machitidwe aliwonse opangidwa ndi anthu, kuphatikiza kuyika kwa dzuwa PV. Pakukhazikitsa kwa dzuwa ndi inverter yomwe imalandira Direct current (DC) kuchokera kuzingwe zamagetsi monga zolowetsera ndikuyika Alternating Current (AC) kupita pagululi kumapeto. Pakukhazikitsa, kukonza pafupipafupi komanso zadzidzidzi ndikofunikira kupatula magawo kuchokera mbali ya AC, chifukwa chake chosinthira chodziyimira payokha chimayikidwa pakati pamapangidwe ndi kulowetsa kwa inverter. Kusintha koteroko kumatchedwa DC isolator chifukwa kumapereka kudzipatula kwa DC pakati pazithunzi za photovoltaic ndi dongosolo lonselo.

Ichi ndi chosinthira chofunikira chachitetezo ndipo chimalamulidwa pamakina onse a photovoltaic malinga ndi IEC 60364-7-712. Zofunikira zaku Britain zimachokera ku BS7671 - Gawo 712.537.2.1.1, lomwe likuti "Kulola kusamalira wotembenuza PV, njira zopatula PV wotembenuza kuchokera ku DC ndipo mbali ya AC iyenera kuperekedwa". Zambiri za DC isolator zimaperekedwa mu "Upangiri Wokhazikitsa PV Systems", gawo 2.1.12 (Edition 2).
