Ulwakhiwo lwe-air circuit breaker (ACB)

Isixhobo sokwaphula isekethe yomoya (I-ACB) yinxalenye ebalulekileyo yenkqubo yokusasazwa kwamandla aphantsi kwaye inomsebenzi obalulekileyo wokuvala imigca engenayo, iibhasi kunye nezinye iisekethe zamandla aphezulu. Ukuqonda izinto ze-air circuit breaker kubalulekile ekuqondeni ukusebenza kwayo kunye neendlela ezahlukeneyo ezikhoyo kwimarike.

Izinto ezisetyenziswa kwi-air circuit breaker zihlala ziquka izixhobo zokunxibelelana, isixhobo sokucima i-arc, indlela yokusebenza, inkqubo yokukhubeka, indawo yokuhlala kunye neyunithi yolawulo. Ezi zinto zisebenza kunye ukuqinisekisa ukusebenza okuthe tye nokukhuselekileyo kwe-circuit breaker kwiindlela ezahlukeneyo zokusebenza. Izinto ezisetyenziswa kwi-air circuit breaker zinokwahlulwa zibe ziintlobo ezizinzileyo kunye nohlobo lwedrowa ngokwendlela yokufakela. Uhlobo oluzinzileyo lusebenzisa iqokobhe lesinyithi, likhulu ngobukhulu, kwaye linenqanaba lokhuseleko eliphantsi. I-air circuit breaker yohlobo lwedrowa isebenzisa indlu yeplastiki yobunjineli, enesakhiwo esincinci ngakumbi, inqanaba lokhuseleko eliphezulu kunye nokugcinwa okulula.

Iimpawu zokukhusela ze-air circuit breakers nazo ziyahluka. Ngokuxhomekeke kwiimpawu zazo zokukhusela, zihlelwa njengezingakhethiyo (udidi A) okanye ezikhethiweyo (udidi B). Ii-Class B circuit breakers zihlala zisebenzisa ukukhutshwa kwe-elektroniki overcurrent ukubonelela ngemisebenzi yokukhusela ixesha elide, ixesha elifutshane kunye nesenzo esikhawulezileyo. Ukongeza, ii-smart air circuit breakers ziza nee-microcontrollers ezakhelwe ngaphakathi, iiyunithi zokubonisa, iinkqubo ze-alamu, amandla okuzihlola, kunye namandla onxibelelwano. Oku kuzivumela ukuba zenze inkqubo yokubeka iliso ngeekhompyutha zoshishino, zibonelela ngamandla olawulo nokubeka iliso aphuculweyo.

Enye yezona zinto zibalulekileyo kwii-air circuit breakers kukuba zinamandla amakhulu kunye nomthamo ophezulu wokuqhekeza. Umzekelo, i-Mutai's CMTW1 type circuit breaker inomlinganiselo wamandla ofikelela kwi-6300A kunye nomlinganiselo wamandla okumelana nexesha elifutshane we-85KA, okuvumela ukuba ibonelele ngokukhetha okuphezulu kunye nozinzo. Nangona kunjalo, kubalulekile ukuqaphela ukuba eli nqanaba lokusebenza liza ngexabiso, njengoko ii-air circuit breakers ezineempawu ezintle kangaka zihlala ziza ngexabiso eliphezulu.

Ngamafutshane, ulwakhiwo lwe-air circuit breaker lubonisa inqanaba eliphezulu lobunjineli kunye netekhnoloji efunekayo ukuyila ezi zinto zibalulekileyo zenkqubo yokusasazwa kwe-voltage ephantsi. Kukho iindlela ezininzi ezithengiswayo, kubandakanya ii-circuit breakers ezizinzileyo, ezinokutsalwa, ezingakhethiyo nezikhethiweyo, kunye neenguqulelo ezikrelekrele ezineempawu zokubeka esweni kunye nolawulo oluphambili ukuze zilungele uluhlu olubanzi lwezicelo. Ngelixa ii-air circuit breakers ezineempawu eziphezulu zinokubiza ngaphezulu, ukusebenza kwazo okuphezulu kunye nokuthembeka kuzenza zibe lutyalo-mali olufanelekileyo ukuqinisekisa ukusebenza ngokukhuselekileyo nangokufanelekileyo kwenkqubo yakho yokusasazwa kombane.

Iqela leMutai liqokelele amava angaphezu kweminyaka elishumi okuvelisa nokuthengisa kwi-iziphuli zesekethe, izixhobo zoqhagamshelwano, amandla amabiniiiswitshi zokudlulisela ngokuzenzekelayo (I-ATS) kunye neenkalo ezinxulumene noko. Silangazelela ithuba lokusebenza nani.
