CDADAose gaosimea fa'atuatuaina ma fa'aulufaleina va'aiga ta'avale DC. O a matou oloa e maualuga, fa'alagolago, ma fa'atekonolosi. Matou te faʻapitoa i le atinaʻeina o fofo faʻapitoa mo pisinisi e pei o le malosi fou, tuʻuina atu ia te oe le atoatoa, tasi-taofi auaunaga OEM.
O le a le DC Circuit Breaker?
A DC ta'avale ta'avale ose masini puipuia fa'apitoa ua fuafuaina e fa'alavelave ai ta'amilosaga sa'o (DC) i lalo o le mamafa, pu'upu'u, po'o tulaga fa'aletonu. E le pei o va'a ta'amilosaga AC e fa'amanuiaina mai fa'aola fa'anatura o lo'o iai nei (100-120 taimi i le sekone i le 50/60Hz), e tatau ona tineia fa'amalosi e ta'avale DC.fa'aauau pea, fa'atasi arc e leai ni mea e tineia ai le tagata lava ia. O lenei eseesega taua e manaʻomia ai tekinolosi faʻamalo faʻapitoa, faʻatupuina le DC breakers faaletino lapopoa, sili atu le lavelave, ma sili atu le taugata nai lo latou AC.
O va'a ta'avale DC e fa'agaoioi i va'aiga eletise mai12V i le 1500V DC, fa'atasi ai ma fa'ailoga o lo'o iai nei2A i le 2500A. Latou te avea o ni vaega taua o le puipuiga i le la photovoltaic (PV) faiga, masini e teu ai malosiaga (BESS), taavale eletise (EV) faʻapipiʻiina infrastru.cture, nofoaga autu o faamatalaga ma le faasoasoaina o le mana DC, alamanuia DC afi pulea, ma faiga eletise o le gataifale.
Ole lu'itau autu ile fa'alavelave DC o lo'o i totonuarc extinction physics: DC arcs tausia koluma mautu plasma ma le vevela e sili atu i le 10,000 °C, e manaʻomia ai le faʻamalosi faʻamalosi, malulu, ma le faʻamalo e ala i maneta, arc chutes, ma mea faʻafesoʻotaʻi faʻapitoa.

Aisea e tu ese ai le matou DC Circuit Breaker
O matou fale gaosi oloa e fai ma sui15 tausaga o fa'apitoa i le DC circuit protection, fa'aolaina va'a e sili atu i tulaga fa'alelalolagi e ala i:
Arc physics tomai: Fa'ata'ita'iga fa'ato'a fa'amaneta fa'atasi ma le fa'avasegaina o le malosi o Lorentz, ausia le <10ms arc fa'aumatia ile 1500V DC
Tu'ufa'atasiga tu'usa'o: I totonu o le fale tungsten-silver fa'afeso'ota'i u'u, NdFeB maneta fa'apotopotoga, ma sima arc chute gaosiga fa'amautinoaina le lelei atoatoa.
Su'ega atina'e: $4M+ fa'aagaga i fale su'esu'e DC maualuga i le taimi nei e mafai ona 20,000A su'ega fa'alavelave, fa'ata'ita'iga fa'avavevave (100,000 fps), ma fa'ata'ita'iga o le si'osi'omaga.
Malosi'aga fa'afouina: Fuafuaga fa'apitoa mo le PV sola (1000V-1500V), teuina o maa (puipuiga e lua), ma le fa'atonuina o le EV (maualuga le fa'afefeteina)
Malosiaga fou: Atina'e o va'a DC fa'avae semiconductor mo <1ms fa'agaioiga i fa'aoga taua o le puipuiga o maa
Mo faʻamatalaga faʻapitoa, faʻamaopoopoina o le puipuiga o le PV o le la, mamanu faʻapipiʻi maa, poʻo le faʻatulagaina o suʻesuʻega falegaosimea, e tuʻuina atu e le matou au inisinia faʻatalanoaga tuusaʻo e faʻamautinoa ai o loʻo faʻamalieina e au masini eletise DC uma manaʻoga saogalemu ma faʻamoemoega faʻalagolago i galuega.

1000V DC Fa'ata'ita'i Fa'ata'ita'iga Va'ava'a
O le CDADA o se kamupani fa'atuatuaina i Saina, e mafai ona ofoina atu le 1000V DC Molded Case Circuit Breaker i le lalolagi atoa. E oʻo atu i le 800A, IEC-tausi, mo PV & DC grids. 2P/4P filifiliga, 20–40kA gau, fa'atasi ma mea fa'aoga. DIN poʻo le faʻapipiʻi laupapa. Fa'atuatuaina e le lalolagi fa'atasi ai le la.
250V DC Laiti Va'ava'ava'ava'a
O le CDADA o se filifiliga lelei e avea ma au fa'atau oloa DAB7-63 250V DC Miniature Circuit Breaker 1P, 1-63A, ma le 6kA le mafai ona gau. O lenei oloa e lelei mo PV sola, telefoni & DC faiga. DIN-rail fa'apipi'i, fa'atasi ai ma fa'ailoga ON/OFF manino ma le tausisia o le RoHS. Fa'amolemole fa'afeso'ota'i matou e maua se tau sa'o a le fale gaosimea.
O le CDADA ose Ta'otoga Ta'avale DC gaosi oloa ma fa'atau oloa i Saina. O la matou fale gaosi oloa e tautuaina pisinisi eseese e pei o le eletise, faufale masini, ma fale gaosi oloa, ofoina atu fofo OEM / ODM fetuutuunai.
