Ukuqonda Umehluko Phakathi Kokuthuthwa Kwe-Magnetic Okushisayo Nokuthuthwa Kwe-elekthronikhi Kuma-Breaker E-Molded Case Circuit

Emkhakheni wobunjiniyela kagesi, ukuphepha nokuthembeka kwezinhlelo zikagesi kubaluleke kakhulu. Ama-Molded case circuit breakers (ama-MCCB) adlala indima ebalulekile ekuvikeleni amasekethe ekuthwaleni ngokweqile kanye namasekethe amafushane. Phakathi kobuchwepheshe obuhlukahlukene obusetshenziswa yi-MCCB, i-thermal magnetic tripping kanye ne-electronic tripping yizindlela ezimbili eziyinhloko. Lesi sihloko sihlose ukucacisa umehluko phakathi kwalezi zindlela ezimbili zokuwa, ngokugxila kakhulu ekusetshenzisweni kwazo, izinzuzo, kanye nemikhawulo.I-Yuye Electrical Co., Ltd.,Umkhiqizi ohamba phambili embonini kagesi, unikeza uhla lwama-MCCB anobuchwepheshe obukhubekayo ukuze kuhlangatshezwane nezidingo zamakhasimende ezahlukene.

Uhambo LukaMazibuthe Olushisayo

Ukujikijela ngogesi okushisayo kuyindlela yendabuko ehlanganisa izindlela ezimbili ezahlukene: ukushisa kanye nogesi odonsayo. Isici sokushisa sisebenza ngesimiso sokushisa okukhiqizwa ukugeleza kwamandla kagesi. Lapho amandla kagesi edlula umkhawulo onqunyiwe, umcu we-bimetallic uyashisa futhi ugobe, ekugcineni ubangele indlela yokujikijela. Le nqubo ihamba kancane futhi ivumela ukulayishwa ngokweqile kwesikhashana ukuthi kudlule kungaphazanyiswa, okuwusizo ezinhlelweni zokusebenza ezivame ukubhekana nemifudlana yokungena, njengezinjini.

Ngakolunye uhlangothi, ingxenye kazibuthe isabela kuma-short circuits. Isebenzisa ikhoyili kagesi edala insimu kazibuthe lapho ugesi omkhulu ugeleza kuyo. Le nsimu kazibuthe idonsa i-lever, ikhube i-circuit breaker cishe ngokushesha, inikeze ukuvikelwa okusheshayo kwe-short circuit. Ukuhlanganiswa kwalezi zindlela ezimbili kwenza i-MCCB eshisayo ne-magnetic ikwazi ukuhlinzeka ngokuvikelwa kokulayisha ngokweqile okuthembekile kanye ne-short circuit.

Uhambo lwe-elekthronikhi

Ngokuphambene nalokho, amadivayisi okuhamba ngogesi asebenzisa ama-elekthronikhi athuthukile ukuqapha ugesi nokuthola amaphutha. Le ndlela isebenzisa ama-microprocessors kanye nokucubungula isignali yedijithali ukuhlaziya amapharamitha kagesi ngesikhathi sangempela. Lapho ugesi udlula umkhawulo obekwe, idivayisi yokuhamba ngogesi ingasabela cishe ngokushesha, inikeze isivikelo esinembile nesithembekile.

Enye yezinzuzo ezibalulekile zokukhubeka nge-elekthronikhi yikhono layo lokuhlinzeka ngezilungiselelo ezingenziwa ngezifiso. Abasebenzisi bangalungisa izilungiselelo zokuhamba ukuze babhekane nokulayisha ngokweqile, i-short circuit, kanye ne-ground fault ngokwezidingo zabo ezithile. Lokhu kuguquguquka kwenza ukukhubeka nge-elekthronikhi kufaneleke kakhulu ezinhlelweni zokusebenza lapho izimo zomthwalo zihluka khona noma kudingeka ukuvikelwa okuqondile.

Umehluko Omkhulu

1. Isikhathi Sokuphendula: Omunye umehluko obaluleke kakhulu phakathi kohambo olusebenzisa amandla kagesi ashisayo kanye nolwe-elekthronikhi yisikhathi sokuphendula. Uhambo olusebenzisa amandla kagesi ashisayo luhamba kancane ngenxa yokuthembela ekukhiqizeni ukushisa, kuyilapho uhambo olusebenzisa amandla kagesi lungasabela ezimweni zamaphutha cishe ngokushesha. Lokhu kusabela okusheshayo kubalulekile ekuvimbeleni ukulimala kwemishini ebucayi.

2. Ukwenza ngokwezifiso: Uhambo lwe-elekthronikhi lunikeza izinga eliphakeme lokwenza ngokwezifiso uma kuqhathaniswa nohambo olusebenzisa amandla kagesi ashisayo. Abasebenzisi bangabeka amanani athile ohambo kanye nokubambezeleka kwesikhathi, banikeze isivikelo esifanelana nohlelo lokusebenza. Ngokuphambene nalokho, amandla kagesi asebenzisa amandla kagesi ashisayoAma-MCCBngokuvamile banezilungiselelo zohambo ezihleliwe, okunciphisa ukuzivumelanisa nezimo.

3. Ukuzwela: Amadivayisi okuhamba ngogesi ngokuvamile azwela kakhulu kunamadivayisi okuhamba ngogesi asebenzisa ukushisa. Lokhu kuzwela kungabona ukugcwala okuncane kanye namaphutha omhlaba, ngaleyo ndlela kuthuthukiswe ukuphepha okuphelele kohlelo lukagesi.

4. Ukugcinwa Nokuxilonga: Ama-MCCB akhubeka ngogesi avame ukuhlonyiswa ngezici zokuxilonga ezihlinzeka ngolwazi olubalulekile mayelana nokusebenza kwesekethe. Lezi zici zisiza ekutholeni izinkinga ezingaba khona ngaphambi kokuba zikhule zibe yizinkinga ezinkulu. Ama-MCCB asebenza ngogesi, yize ethembekile, awanawo amakhono athuthukile okuxilonga.

5. Izindleko: Ngokuvamile, ama-MCCB anomoya oshisayo ashibhile kune-MCCB enomoya oshisayo. Ukulula komklamo oshisayo nomoya oshisayo kusiza ukugcina izindleko zokukhiqiza ziphansi. Kodwa-ke, ukutshalwa kwezimali kokuqala ohlotsheni lomoya oshisayo kungavunyelwa izici zokuvikela ezithuthukisiwe kanye nokwenza ngokwezifiso ezikunikezayo, ikakhulukazi ezinhlelweni ezibalulekile.

uhlelo lokusebenza

Ukukhetha phakathi kokusebenzisa i-thermal-magnetic kanye ne-electronic tripping kuncike kakhulu ekusetshenzisweni okuthile kanye nezinga lokuvikelwa elidingekayo. Ama-MCCB asebenzisa i-thermal-magnetic avame ukusetshenziswa ezindaweni zezimboni lapho ama-current currents avame khona, njengezinhlelo zokusebenza ze-motor. Amandla awo okubekezelela ukugcwala ngokweqile kwesikhashana awenza afaneleke kahle kulezi zindawo.

Ngakolunye uhlangothi, ama-MCCB akhubeka ngogesi afaneleka kakhulu ezinhlelweni zokusebenza ezidinga ukuvikelwa nokuqapha okunembile. Avame ukusetshenziswa ezakhiweni zezentengiselwano, ezikhungweni zedatha, nakwezinye izikhungo ezisebenzisa imishini kagesi ebucayi. Amandla okwenza ngezifiso izilungiselelo zohambo nokuqapha ukusebenza kwenza uhambo lwe-elektroniki lube yisinqumo esikhethwayo kulezi zimo.

Kokubili ukugoba okushisayo okune-magnetic kanye noku-electronic kunezinzuzo kanye nemikhawulo yazo eyingqayizivele. Ama-MCCB ashisayo anikeza isivikelo esithembekile ngomklamo olula, okwenza afaneleke ezinhlobonhlobo zezicelo zezimboni. Ngokuphambene nalokho, ama-MCCB agoba ngo-electronic anikeza izici ezithuthukisiwe, ukwenza ngokwezifiso, kanye nezikhathi zokuphendula okusheshayo, okwenza kube kuhle kakhulu ezinhlelweni zokusebenza ezibucayi nezibucayi.

I-Yuye Electrical Co., Ltd.iyaqaphela ukubaluleka kwalokhu kungafani futhi inikeza uhla olubanzi lwe-MCCBs oluhlanganisa ubuchwepheshe bokukhubeka obusebenzisa ugesi kanye nobuchwepheshe bokukhubeka obusebenzisa ugesi. Ngokuqonda umehluko phakathi kwalezi zindlela ezimbili zokukhubeka, onjiniyela bakagesi kanye nochwepheshe bangenza izinqumo ezinolwazi ezithuthukisa ukuphepha nokuthembeka kwezinhlelo zabo zikagesi. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukukhetha indlela yokukhubeka kuzodlala indima ebalulekile ekwakheni ikusasa lezixazululo zokuvikela zikagesi.
