Intshayelelo Kwiinkqubo zokusasazwa kwamandla kwimizi-mveliso, ii-circuit breakers zidlala indima ebalulekileyo ekukhuseleni izixhobo, ukuqinisekisa ukhuseleko lwabasebenzi, kunye nokugcina ukusebenza kuqhubeka. Ukukhetha i-breaker engalunganga kunokubangela ukukhubeka rhoqo, ukukhuselwa okungonelanga kwempazamo, okanye nokuba yintlekele...

IiMolded Case Circuit Breakers (iiMCCB) zidlala indima ebalulekileyo kwiinkqubo zokusasazwa kwamandla aphantsi ngokubonelela ngokhuseleko oluthembekileyo kwiingxaki zokugqithisa kunye nee-short circuits. Phakathi kwezilinganiso ezahlukeneyo, iklasi ye-250 amp isetyenziswa kakhulu kwizakhiwo zorhwebo, kwizityalo zoshishino, nakwiprojekthi yeziseko zophuhliso...

Izakhiwo ezinkulu zorhwebo ezifana neevenkile ezinkulu, iiofisi, izikhululo zeenqwelo-moya, kunye neendawo zeendibano zifuna umbane othembekileyo kakhulu ukuxhasa imisebenzi yemihla ngemihla. Ukuphazamiseka kombane okanye umbane ongazinzile kunokukhokelela kwiingozi zokhuseleko, ilahleko yokusebenza, kunye nomonakalo wezixhobo. Yiyo loo nto umntu...

IiSwitshi zoThumelo oluZenzekelayo (ii-ATS) zizinto ezibalulekileyo kwiinkqubo zobonelelo lwamandla amabini, ziqinisekisa ukudluliselwa kwamandla okungenamthungo phakathi komthombo wombane kunye nomthombo wamandla oxhasayo. Kwiinkqubo zokusasazwa kwamandla eziphakathi nezinkulu, umlinganiselo wangoku we-630A usetyenziswa kakhulu ngenxa yokukwazi kwawo ukuxhasa...

IiSwitshi zokuThumela eziZenzekelayo (ii-ATS) zizinto ezibalulekileyo kwiinkqubo zanamhlanje zokubonelela ngombane ezimbini. Ziqinisekisa ukuba imithwalo ebalulekileyo iyaqhubeka nokusebenza ngaphandle kokuphazamiseka xa umbane ophambili ungaphumeleli okanye ungazinzi. Phakathi kweentlobo ezahlukeneyo ze-ATS, i-Solenoid Type ATS ivelele ngokukhawuleza kwayo...

IiSwitshi zoThumelo oluZenzekelayo (ii-ATS) zingumqolo weenkqubo zamandla ezithembekileyo, ziqinisekisa ukutshintsha okungenamthungo phakathi kwemithombo yamandla ephambili kunye neyogcino ukuze kuthintelwe ixesha lokungasebenzi elibizayo. Phakathi kweendlela eziqhelekileyo, i-3P kunye ne-4P zisetyenziswa kakhulu kodwa zihlala zingaqondwa kakuhle—ingakumbi xa zidibene ne-m...

Iswitshi yokudlulisa amandla e-Ats Dual Power Automatic Transfer yinxalenye ebalulekileyo kuyo nayiphi na inkqubo yokukhusela umbane yanamhlanje. Ihlala ijonga ukufumaneka kombane oyintloko kwaye idlulisela umthwalo ngokuzenzekelayo kumthombo wogcino nanini na xa kukho iingxaki. Oku kuqinisekisa ukusebenza okungaphazanyiswayo kwe-cri...

Iswitshi yokudlulisa ngokuzenzekelayo (i-ATS) sisixhobo esibalulekileyo kwiinkqubo zombane ezimbini, ezisetyenziselwa kakhulu ukutshintsha ngokuzenzekelayo phakathi kombane ophambili kunye nombane oxhasayo ukuqinisekisa umbane oqhubekayo kwimithwalo ebalulekileyo. Ufakelo oluqhelekileyo nolwesayensi alupheleli nje ekunxibelelaneni nokhuseleko...

Intshayelelo Iswitshi yokudlulisa ngokuzenzekelayo (i-ATS) yinxalenye ebalulekileyo kwiinkqubo zonikezelo lwamandla amabini, enoxanduva lokuqinisekisa amandla angaphazanyiswa kwimithwalo ebalulekileyo. Iswitshi ezenzekelayo yamandla amabini inokudlulisa imithwalo ngokukhawuleza nangokuthembekileyo kumthombo wamandla omiyo xa unikezelo lokuqala lungaphumeleli okanye...

1. Uhlalutyo lweempawu zomthwalo kunye nokuhambelana komthamo 1.1 Ukuchongwa kohlobo lomthwalo Kuqhutywa uhlalutyo oluneenkcukacha lohlobo lomthwalo (oluchaseneyo, olubangela ukuguquguquka, olunamandla, okanye oluxutyiweyo). Iintlobo ezahlukeneyo zemithwalo zinempembelelo ebalulekileyo kwi-current surge, iimpawu zokuqala ze-ATS. Umzekelo...
