I-BYM3DC Series 1500V Photovoltaic Molded Circuit Breaker

Lokhu I-Molded Case Circuit Breaker ihlanganisa izindlela zokuvikela ezithuthukile ezibalulekile kwingqalasizinda yamandla avuselelekayo. Ifaka ukuvikelwa kokulibaziseka kokulayishwa okunembe kwesilinganiso okunembayo okuvimbela ukuwohloka kwe-conductor kusuka kuma-overcurrents aqhubekayo, kanye nokuvikelwa kweso leso sikhathi kwesifunda esifushane esihamba phakathi kwama-millisecond phakathi nemicimbi yephutha. I-thermal-magnetic tripping mechanism isebenza ngokuzimela emithonjeni yamandla yangaphandle, iqinisekisa ukusebenza okuhlulekayo ngesikhathi sokuphazamiseka kwegridi. Ngayo yomibili imisebenzi esethwe efekthri kumazinga e-IEC, i-breaker iletha ukuvikelwa okuhlanganisiwe kwamabhokisi okuhlanganisa i-PV, okokufaka kwe-inverter, nezinhlelo zokugcina ibhethri.

Itholakala kukho kokubili ukulungiselelwa kwe-2-pole (2P) kanye ne-3-pole (3P), i-BYM3DC ijwayelana nezakhiwo zesistimu ehlukahlukene. Idizayini ehlangene ikhulisa isikhala sephaneli ngenkathi igcina imvume yokuhlukaniswa egcwele engu-1500V. Izindlu zayo ze-thermoset eziqiniswe nge-fiberglass zinikeza amandla akhethekile we-dielectric kanye nokumelana nokuwohloka kwe-UV, amazinga okushisa eqile (-25°C kuya ku-+70°C), kanye nezindawo ezibolayo. Isistimu yokuxhumana yamakhefu aphindwe kabili ezungezayo ifinyelela ukucisha kwe-arc ngokushesha ngokuchezuka kwendawo kazibuthe, equkethwe ngaphakathi kwama-arc chute avaliwe avimbela ukuphuma kwe-plasma.

Ukuthobelana nezindinganiso zamazwe ngamazwe ze-photovoltaic (IEC 60947-2, UL 489B) kuqinisekisa ubunjiniyela bokuphepha bephula. I I-Molded Case Circuit Breaker ihlanganisa izindlela zokuqinisekisa ukuhlolwa ezivumela ukuqinisekiswa okuphephile kokusebenza ngaphansi komthwalo. Ibhokisi layo letheminali elivalwe kathathu livimbela ukungena kothuli/umswakama (IP40), kuyilapho izikulufa zetheminali ezine-torque-limited zivimbela ukulimala kukakhondatha ngesikhathi sokufakwa. Ukukhuthazela komshini kwephula kudlula imisebenzi engu-10,000 ngesikhathi esilinganiselwe ngokugcwele, okuqinisekisa amashumi eminyaka esevisi yamahhala ezindaweni ezidinga kakhulu.

I-BYM3DC photovoltaic DC breaker ibalulekile ekufakweni kwesimanje kwelanga. Ivikela ukuhlangana okubalulekile phakathi kwezintambo ze-PV nama-inverters, ivikela amabhange ebhethri ezinhlelweni zokugcina, futhi ihlukanise amaphutha kumaphaneli okusabalalisa e-DC. Onjiniyela bacacisa lesi sixazululo ngenhlanganisela yaso engenakuqhathaniswa yokubekezelela amandla kagesi aphezulu (1500VDC), umthamo wamanje wama-800A, kanye nobuchwepheshe obuzinikele be-DC obuletha ukuvikelwa okuqinile, okuhambisana nekhodi okudingekayo kumapulazi elanga, uphahla lwezimboni, namaphrojekthi ama-microgrid emhlabeni jikelele.
