Ngaba ufuna i-Earth Leakage Circuit Breaker ekumgangatho ophezulu kwaye ehlala ixesha elide?CDADAinikeza izisombululo ezibanzi ze-OEM. Njengomenzi othembekileyo onefektri yethu, sibonelela ngewaranti yeminyaka emi-3 kwiimveliso zethu.

Yintoni i-Earth Leakage Circuit Breaker (CBR)?

AnISaphuli seSekethe sokuvuza koMhlaba (CBR), kwaziwa njengeISaphuli seSekethe sokuvuza koMhlaba kunye noKhuseleko oluDibeneyo oluPhezulu (CBR) ngokwe-IEC 60947-2 iSihlomelo B, sisixhobo esiphucukileyo sokhuselo lombane ophantsi odibanisaukhuseleko lwangoku (ukuvuza komhlaba). ngeukulayisha ngaphezulu kunye nokhuseleko lwesekethe emfutshane kwiyunithi enye yecala elibunjiweyo. Ukusebenza kwiivolthi ezilinganisiweyo ukuya kuthi ga415V AC (50/60Hz) ngoreyithingi lwangoku olusuka16A ukuya ku-800A, ii-CBR zisebenza njengezixhobo zokhuseleko ezibanzi kushishino, urhwebo, kunye nosetyenziso lweziseko ezingundoqo ezibalulekileyo .

Ngokungafaniyo nokuzimelaIzaphuli zeSekethe ezishiyekileyo (RCCBs)ezibonelela kuphela ngokhuseleko lokuvuza komhlaba, ii-CBR ziyadibanisa:

Ukhuseleko lwe-Thermal-magnetic okanye i-electronic overcurrent (L-S-I iigophe)

Ukufunyanwa kwangoku okushiyekileyo (10mA ukuya 1000mA ubuntununtunu)

Umthamo wokuqhekeka wesekethe emfutshane ukuya kuthi ga kwi-85kA

Oku kudityaniswa kuphelisa imfuno yokudibanisa i-MCB / RCCB eyahlukileyo, ukunciphisa indawo yokufakela kunye nokuphucula ukuthembeka kokulungelelanisa.

Ubuchwephesha bokuguqula iToroidal: Imveliso engundoqo ye-nanocrystalline yangaphakathi, ukuchaneka kwe-automation, kunye novavanyo olubanzi lwe-CBCT oluqinisekisa <± 5% ukuchaneka kobuntununtunu

Ukuhlanganiswa ngokuthe nkqo: Ukusuka ekusetyenzweni kwezinto ezingundoqo ukuya kwindibano yokugqibela, ulawulo olupheleleyo kumacandelo abalulekileyo (i-toroidal transformers, iiyunithi zohambo lwe-elektroniki, iimeko ezibunjiweyo)

Iziseko zovavanyo olukwinqanaba eliphezulu: I-$3M+ ityale imali kwiinkqubo zovavanyo ezihlanganisiweyo ze-CBR ezikwaziyo ukugqithiswa kwangaxeshanye kunye nokuqinisekiswa okushiyekileyo kwangoku, uHlobo lwe-B yovavanyo lobuntununtunu lwe-DC, kunye nokuthotyelwa kwe-EMC

Isicwangciso sesiqinisekiso sehlabathi: Ukuthotyelwa kwemigangatho emininzi kuvumela ukungena kwimarike ngaphandle komthungo kumazwe angama-100+ ngaphandle kovavanyo olungafunekiyo

Kwiinkcukacha zobugcisa, izifundo zokulungelelanisa ezikhethiweyo, isikhokelo sesicelo soHlobo lwe-B, okanye ukucwangciswa kophicotho lwefektri, iqela lethu lobunjineli libonelela ngokubonisana ngokuthe ngqo ukuqinisekisa ukuba ulwakhiwo lwakho lokhuseleko lokuvuza komhlaba luhlangabezana neemfuno zokhuseleko lwabasebenzi kunye neenjongo zokuqhubeka nokusebenza.

CDADA yi Earth Leakage Circuit Breaker umenzi kunye nomthengisi e China. Umzi-mveliso wethu usebenza kumashishini ahlukeneyo afana neenkqubo zamandla, i-automation yokwakha, kunye nokuveliswa kwemizi-mveliso, ukubonelela ngezisombululo ze-OEM / ODM eziguquguqukayo.
