ISahluli seSekethe esiSisalelayo esiSisalelayo soKhuseleko loMbane olongezelelweyo

Iisaphuli sesekethe sangokuyeyoluhlu lwe-JCB3LM-80, olubonelela ngokuvuza okubanzi, ukugcwala kunye nokhuseleko olufutshane lwesekethe. I-residual current circuit breaker yenzelwe ukusetyenziswa kweendawo zokuhlala kunye nezorhwebo ukuze kuqinisekiswe ukusebenza okukhuselekileyo nokusebenzayo kwesekethe.

I-Residual current circuit breakers zizixhobo ezibalulekileyo zokhuseleko ezisebenza ukukhusela abantu kunye nepropathi kwiingozi zombane. Njengenxalenye yochungechunge lwe-JCB3LM-80, ii-breakers zangoku eziseleyo zibonelela ngokukhuselwa kokuvuza, ukukhuselwa komthwalo ogqithisiweyo kunye nokukhuselwa kwesiphaluka esifutshane kwiyunithi enye. Oku kwenza ukuba ii-breaker circuit zangoku ezishiyekileyo zibe licandelo elibalulekileyo lokuqinisekisa ukusebenza ngokukhuselekileyo kweesekethe kumakhaya, kwiiofisi nakwiindawo zoshishino. I-Residual current circuit breakers ibona ukungalingani kwangoku kwaye i-circuit breaker ikhupha ngokuzenzekelayo isiphaluka ukuthintela iingozi kunye nomonakalo onokuthi ukhusele kakhulu inkqubo yombane kunye nokukhusela ngakumbi ukhuseleko lwabasebenzisi.

Enye yeenzuzo eziphambili ze-residual current circuit breaker kukuguquguquka kwayo. Inoluhlu olubanzi lweereyithingi zangoku (ukusuka kwi-6A ukuya kwi-80A) ukuhlangabezana neemfuno ezahlukeneyo zomthwalo wombane. I-breaker circuit iphinde ixhase ukucwangciswa kwee-multi-pole, kubandakanywa i-1P + N, i-2-pole, i-3-pole, i-3P + N kunye ne-4-pole, efanelekileyo kwiinkqubo ezahlukeneyo zocingo. Ingaba ufuna ukukhusela isiphaluka sokuhlala sesigaba esisodwa okanye ukufakwa kwesigaba sesithathu semizi-mveliso, le ntsalela yangoku yesiphaluka inokubonelela ngokusebenza okuthembekileyo.

Intsalela yangoku yezaphuli zesekethe ziyilelwe ukuhlangabezana nemigangatho engqongqo yokhuseleko, kubandakanywa nokuthotyelwa kwe-IEC61009-1. Ngomthamo wokuphulwa kwe-6kA, ii-breaker circuit zangoku ezishiyekileyo ziyakwazi ukusingatha i-current fault currents ngaphandle kokuphazamisa ukusebenza. Ii-breaker circuit zangoku eziseleyo zifumaneka kwiimodeli zombini ze-A kunye ne-AC ukuze kuqinisekiswe ukuhambelana noluhlu olubanzi lweenkqubo zombane. I-Residual yangoku ye-circuit breaker ilinganise iinketho zokusebenza eziseleyo - 30mA, 50mA, 75mA, 100mA kunye ne-300mA - vumela abasebenzisi ukuba bakhethe inqanaba lobuntu obufanelekileyo kwisicelo sabo esithile.

Ukuqina kunye nokuchaneka ziimpawu ze-residual current circuit breakers. Ulwakhiwo olomeleleyo lwabaphuli beesekethe abashiyekileyo bangoku luqinisekisa ukusebenza okuhlala ixesha elide nakwiindawo ezifunayo. Ukukwazi kwee-circuit breakers 'ukubona kunye nokuphendula ukungalingani kwangoku kwemizuzu kubenza basebenze ngokukodwa ekuthinteleni imililo yombane kunye nomngcipheko wombane. Eli nqanaba lokukhusela liyimfuneko ekugcineni ukhuseleko kwiindawo apho izixhobo zombane zisetyenziswa rhoqo.

Ii-breaker circuit zangoku ezishiyekileyozisisombululo esithembekileyo kunye nesiguquguqukayo sokhuseleko lombane. Iimpawu zabo zokukhusela ezibanzi, uluhlu olubanzi lweendlela, kunye nokuthotyelwa kwemigangatho yamazwe ngamazwe kubenza babe sisixhobo esiyimfuneko kubanini bezindlu kunye namashishini. Ngokuqinisekisa ukusebenza okukhuselekileyo kweesekethe zombane, ii-breaker circuit zangoku ezishiyekileyo zinceda ukukhusela iingozi, ukukhusela impahla, nokukhuthaza uxolo lwengqondo.
