Isihlukanisi seDC

123

Imishini eklanywe kahle kakhulu kule ndawo yonke ngumzimba womuntu. Inesistimu yokuzivikela nokuzilungisa eyakhelwe ngaphakathi enhle kakhulu. Ngisho nalolo hlelo oluhlakaniphe kakhulu ludinga ukulungiswa ngezikhathi ezithile. Futhi kunjalo ngalo lonke uhlelo olwenziwe ngabantu, kufaka phakathi ukufakwa kwelanga kwe-PV. Ngaphakathi kokufakwa kwelanga kukhona i-inverter ethola i-Direct current (DC) kusuka ezintanjeni zelanga njengokufaka futhi ikhipha i-Alternating Current (AC) kugridi ekugcineni komkhiqizo. Ngesikhathi sokufakwa, ukugcinwa okujwayelekile kanye nezimo eziphuthumayo kuyadingeka ukuhlukanisa amapaneli ohlangothini lwe-AC, ngakho-ke, kufakwa inkinobho yokuzihlukanisa esebenza ngesandla phakathi kwamapaneli nokufakwa kwe-inverter. Ukushintsha okunjalo kubizwa ngokuthi yi-DC isolator ngoba kunikeza ukuhlukaniswa kwe-DC phakathi kwamaphaneli we-photovoltaic kanye nalo lonke uhlelo.

Lesi iswishi ebalulekile yokuphepha futhi igunyaziwe ohlelweni ngalunye lwe-photovoltaic ngamandla ngokwe-IEC 60364-7-712. Imfuneko yaseBrithani ehambisanayo ivela ku-BS7671 - Ingxenye 712.537.2.1.1, ethi "Ukuvumela ukugcinwa kwesiguquli se-PV, izindlela zokuhlukanisa isiguquli se-PV ohlangothini lwe-DC futhi uhlangothi lwe-AC kufanele lunikezwe". Imininingwane ye-DC isolator uqobo inikezwe ku- "Umhlahlandlela Wokufakwa Kwama-PV Systems", isigaba 2.1.12 (Edition 2).
