Sei DC Circuit Dziviriro Ichive Yakakosha kune Remangwana reMasimba Masimba?

Indasitiri yemagetsi yepasi rose iri kuramba ichitsamira pane yakananga ikozvino. Solar photovoltaic arrays, bhatiri simba rekuchengetedza masisitimu, magetsi emagetsi ekuchaja zviteshi, midziyo yekufonera, uye data data zvese zvine zvakakosha DC zvikamu. Sezvo izvi zvikumbiro zvichikura, kuchengetedzwa kwedunhu kuri kufamba kubva kune chikamu chinotsigira kuenda kune chepakati chikamu chekuchengetedza system. ADC circuit breakerinofanira kusunungura ikozvino yakashata nekukurumidza uye zvakachengeteka, ichidzikamisa kukuvadzwa kwetambo, maconverter, mabhatiri, uye midziyo yakabatana.

Kukanganisa DC kwakasiyana nehunyanzvi nekukanganisa AC. Mudunhu re AC, ikozvino inoyambuka zero kakawanda pasekondi, iyo inobatsira kudzima arc yemagetsi. DC haina yakasikwa zero kuyambuka, saka arc inogona kuramba yakagadzikana mushure mekusangana kwakasiyana. Mabreaker akagadzirirwa DC saka anoda akakodzera ekuonana zvimiro, arc chutes, magineti blowout marongero, insulation madaro, uye wiring masisitimu. Iyo AC breaker haifanirwe kufungidzirwa yakakodzera DC sevhisi nekuda kwekuti chiyero chayo chazvino chinoratidzika kunge chakakwana.

Imwe yakajeka indasitiri maitiro ndeyekuenda kune yakakwira system voltages uye yakakura simba density. Yepamusoro DC voltage inogona kuderedza ikozvino kune imwechete inofambiswa simba, ichibatsira yakaderera conductor kurasikirwa uye tambo zvinodiwa. Nekudaro, zvakare inoita kuti insulation yekubatanidza uye kukanganiswa kwearc kuwedzere kudiwa. Kusarudzwa kwechigadzirwa kunofanirwa kufunga nezve yakayerwa kushanda kwemagetsi, yakayerwa ikozvino, nhamba yemapango, pfupi-sekete yekutyora simba, nharaunda yekushandisa, uye yakatsanangurwa yemugadziri nzira yekubatanidza. Polarity zvinodiwa zvinonyanya kukosha kune mamwe DC breaker dhizaini.

Imwe muitiro ndeyepedyo kurongeka pakati pemabreaker uye emagetsi ekutarisa. Masisitimu emagetsi emazuva ano ari kuwedzera kushandisa masensa, zvidzori, uye network dzekutaurirana kuona kupisa kwakanyanya, kuwandisa, kukanganisa kwekudzivirira, uye maitiro asina kujairika ekushanda. Kudzivirirwa kweMechanical kunoramba kwakakosha, asi kuri kuita chikamu chekuvaka kwakafara kwekuvaka kunogona kusanganisira fuse, surge yekudzivirira michina, macontactor, insulation yekutarisa michina, uye mabhatiri manejimendi masisitimu. Kusarudzika pakati pemichina yekukwira nekudzika kuri kugamuchirawo kutariswa kwakawanda nekuti kuvharika kusingakoshi kunogona kukanganisa tambo yesolar, rack yekuchengetera, kuchaja kabati, kana maindasitiri maitiro.

Iyo DAM3DC-250 inoratidzwa neShanghai Dada Electricinoratidza mhando yeakaumbwa-kesi DC breaker inoshandiswa mukugovera kwepamusoro-ikozvino. Mamiriro anoonekwa anoratidza chiyero chakayerwa che250 A, DC rated voltage ye1000 V, inotyora simba ye20 kA, uye maviri-pole dhizaini. Aya maitiro anotsanangura chinangwa chayo chemagetsi; ivo pachavo havataridzi kukodzera kwega kwega kuiswa. Mainjiniya anofanirwa kuramba achi ongorora iyo chaiyo yenguva-pfupi nhanho, saizi yekondakita, ambient tembiricha, yakavharirwa mamiriro, hunhu hwekuremerwa, kukwirisa, mazinga anoshanda, uye inodiwa kuchengetedza kurongeka.

Kune vashandisi vekupedzisira, mavara akajeka uye zvinyorwa zvakakosha zvakaenzana, nekuti kuisirwa kwakaringana, kugadzirisa, uye kutsiva sarudzo zvinoenderana nekuziva mareti akasimbiswa echishandiso uye zvipimo mubasa.

Tichitarisa kumberi, vatengi vanoisa simbiso huru pakusimbisa-chaicho chekushandisa pane kusarudza zvishandiso nechiyero chazvino chete. Kuvimbika kweDc dziviriro kunoenderana nekuenderana kwemagetsi emagetsi, kukwana kwakakwana kwekukanganisa, kurongeka kwakaringana danda, kuisirwa kudzorwa, uye kuongorora nguva nenguva. Sezvo chizvarwa chinovandudzwa, chekuchengetedza, uye chekufambisa chemagetsi chiri kuramba chichikura, kunzwisisa izvi zvakakosha kuchabatsira vanogadzira masisitimu kuderedza njodzi uye kuvaka mamwe akavimbika DC network.
