Isingeniso:
I-JCB3-63DC miniature DC circuit breaker iklanyelwe i-solar / photovoltaic PV system, isitoreji samandla kanye nezinye izinhlelo zokusebenza zamanje ze-DC eziqondile.Ikakhulukazi ibekwe phakathi kwamabhethri nama-inverter e-hybrid.
I-JCB3-63DC DC i-circuit breaker ihlinzeka ngokucisha i-arc yesayensi kanye nobuchwepheshe bokuvimbela i-flash ukuze kugcwaliseke ukuphazamiseka kwamanje okusheshayo nokuphephile.
I-JCB3-63DC DC i-circuit breaker iyisisetshenziswa sokuvikela esifakwe kokubili ukukhishwa okushisayo nokwe-electromagnetic okutholakala ngezinguqulo zesigxobo esingu-1, 2pole, 3 pole kanye nezi-4.Umthamo wokushintshwa ngu-6kA ngokwe-IEC/EN 60947-2.I-voltage elinganiselwe ye-DC ingu-250V isigxobo ngasinye, i-voltage elinganiselwe ifika ku-1000V DC.
I-JCB3-63DC i-circuit breaker iyatholakala ngemisinga elinganiselwe ye-2A ukuya ku-63A.
I-JCB3-63DC dc circuit breaker inikeza izici ezintsha, uxhumano olungcono, ukusebenza okuphakeme kanye namazinga okuphepha anyukile.Umthamo wayo wokuphuka ungafika ku-6kA.
I-JCB3-63DC dc circuit breaker ingakhiywa (ngedivayisi yokukhiya) endaweni OFF njengesinyathelo sokuphepha sokususwa kwe-PV inverter.
Njengoba iphutha lamanje lingageleza libheke emuva kuya kokusebenza kwamanje, i-JCB3-63DC Circuit breaker ingakwazi ukubona futhi ivikele kunoma iyiphi yamanje ye-bidirectional.Ukuqinisekisa ukuphepha kokufakwa, kuyadingeka, kuye ngezinhlobo ezahlukahlukene zohlelo, ukuhlanganisa i-breaker circuit ne:
• idivayisi yamanje eyinsalela ekugcineni kwe-AC,
• umtshina wefault passage (umshini wokugada i-insulation) ekugcineni kwe-DC
• isinqamuli sesekhethi sokuvikela umhlaba ekugcineni kwe-DC
Kuzo zonke izimo, isinyathelo esisheshayo esizeni sizodingeka ukusula iphutha (ukuvikelwa akuqinisekisiwe uma kwenzeka iphutha eliphindwe kabili).I-JIUCE JCB3-63DC dc Ama-Circuit breaker awazwelani ne-polarity: (+) kanye (-) izintambo zingahlehliswa ngaphandle kobungozi.I-circuit breaker ithi: ilethwe ngezithiyo ezintathu ze-inter-pole ukunikeza ibanga elikhulayo lokuhlukaniswa phakathi kwezixhumi ezimbili eziseduze.
