Ma "solar DC circuit breakers": kuona kuchengetedzeka uye kushanda zvakanaka
MaDC circuit breaker anoita basa rakakosha mukuchengetedzeka uye kushanda zvakanaka kwema solar power systems. Sezvo kudiwa kwesimba rinogona kushandiswazve kuri kuramba kuchikura, kukosha kwemidziyo yekudzivirira ma circuit yakavimbika uye inoshanda zvakanyanya hakugone kupfuudzwa zvakanyanya. Munyika yezuva, maDC circuit breaker zvinhu zvakakosha zvinobatsira kuona kuti ma photovoltaic (PV) systems anoshanda zvakanaka uku achidzivirira njodzi dzinogona kuitika dzemagetsi.
Masisitimu esimba rezuva anoshandiswa nesolar panels kuti ashandure chiedza chezuva kuita magetsi. Mapanels aya anogadzira simba remagetsi rakananga (DC), iro rinoiswa mu inverter uye rinoshandurwa kuita alternating current (AC) kuti rishandiswe nedzimba, mabhizinesi negrid. Mukuita uku, ma DC circuit breakers anoshanda senzira yakakosha yekuchengetedza, achidzivirira system kubva pa overcurrent, short circuits, nezvimwe zvikanganiso zvemagetsi zvinogona kukonzera kukuvara kana kuisa njodzi kuvashandi.
Rimwe remabasa makuru eDC circuit breakers mukushandiswa kwezuva nderekumisa kufamba kwemagetsi kana paine chikanganiso kana mamiriro ekushanda asina kujairika. Nekuita izvi, zvinobatsira kudzivirira kukuvara kwema solar panels, waya, nezvimwe zvikamu zve system uye kuderedza njodzi yemoto kana kurohwa nemagetsi. Pamusoro pezvo, DC breakers dzinogonesa vashandi vekugadzirisa kuti vaparadzanise zvikamu zvakati zve solar array kuti zvigadzirwe kana kugadziriswa pasina kudzima system yese.
Zvinhu zvakakosha zvinofanirwa kutariswa pakusarudza DC circuit breaker yekuisa solar. Izvi zvinosanganisira voltage uye current ratings yema solar panels ne inverter, rudzi rwePV array configuration (senge series kana parallel), uye zvinodiwa zvekushandisa. Zvakakosha kusarudza circuit breaker inoenderana nehunhu hwakasiyana hwe solar power generation system uye inogona kupa dziviriro yakavimbika pasi pemamiriro akasiyana ezvakatipoteredza.
Mumakore achangopfuura, kufambira mberi muhunyanzvi hweDC circuit breaker kwakatungamira mukuvandudzwa kwemidziyo yakasarudzika uye inoshanda zvakanaka yakagadzirirwa kushandiswa kwezuva. Semuenzaniso, mimwe circuit breaker yakagadzirirwa kugamuchira voltage yakakwira uye mazinga emagetsi anowanzo batanidzwa ne solar arrays, nepo mimwe ichipa maficha akawedzerwa akadai sekuona kukanganisa kwe arc uye kugona kudzima nekukurumidza. Izvi zvitsva hazvingogadzirise kuchengetedzeka nekuvimbika kwemasisitimu esimba rezuva chete, asiwo zvinobatsira kuvandudza mashandiro ese uye hupenyu hwebasa remidziyo.
Pamusoro pezvo, kubatanidzwa kwehungwaru nemabasa ekutaurirana muDC circuit breakers dzemazuva ano kunogona kuwedzera kutarisa nekudzora kuiswa kwesimba rezuva. Nekushandisa nzira dzekutaurirana dzedhijitari uye kugona kwekutarisira kure, vashandi vanogona kuona mamiriro esimba remagetsi panguva chaiyo, kuona matambudziko angangoitika, uye kutora matanho ekugadzirisa mashandiro ehurongwa. Iyi nhanho yekuonekwa nekudzora kwakakosha pakuona kushanda zvakanaka kwesimba remagetsi rezuva uye kuderedza nguva yekumira kwesimba nekuda kwekutadza kushanda kwesimba remagetsi.
Sezvo shanduko yepasi rose kuenda kusimba rinogara kwenguva refu ichienderera mberi, kudiwa kwemaDC circuit breaker emhando yepamusoro ekushandiswa kwezuva kunotarisirwa kuwedzera. Vagadziri nevatengesi vanoramba vachiedza kuzadzisa kudiwa uku nekupa zvigadzirwa zvakasiyana-siyana zvinosangana nezvinodiwa zvakasimba zvekuchengetedza uye mashandiro eindasitiri yezuva. Ingave iri nzvimbo yekugara, yekutengeserana kana yekushandira, basa reDC circuit breaker mukuchengetedza kuvimbika kwezvivakwa zvemagetsi harigone kufuratirwa.
Muchidimbu, maDC circuit breaker chinhu chakakosha mukugadzira magetsi ezuva, zvichipa dziviriro inodiwa kubva kumatambudziko emagetsi uye zvichivimbisa kushanda kwakachengeteka uye kwakavimbika kwemidziyo ye photovoltaic. Sezvo tekinoroji ichiramba ichifambira mberi uye kutarisisa simba rinogona kudzokororwa kuri kukura, kugadzirwa kwemhinduro dzekudzivirira dunhu dzakagadzirirwa kushandiswa kwezuva kucharamba kuchiita basa guru mukugadzira ramangwana rekugadzira magetsi anoenderera mberi. Nekuisa pamberi kusarudzwa nekushandiswa kwemaDC circuit breaker emhando yepamusoro, vane chekuita neindasitiri yezuva vanogona kuchengetedza mwero wepamusoro wekuchengetedzeka uye kushanda zvakanaka uku vachibatsira mukusimudzira zvirongwa zvesimba rakachena.
