Ukuqonda Ukulayishwa Kwesiyingi kanye Nokuvikelwa Kwesekethe Emfishane Kumabhulaki Esifunda Abunjiwe: Iqhaza Le-Thermal Magnetic and Electronic Tripping Mechanisms

Emkhakheni wobunjiniyela bakagesi, ukuphepha nokuthembeka kwezinhlelo zikagesi kubaluleke kakhulu. Enye yezinto ezibalulekile eziqinisekisa lokhu kuphepha i-molded case circuit breaker (MCCB). Lawa madivaysi aklanyelwe ukuvikela amasekhethi ekulayishweni ngokweqile namasekhethi amafushane angabangela ukwehluleka okuyingozi kanye nezingozi. Lesi sihloko sibheka kabanzi ukuthi izigebengu zesekhethi ezibunjiwe zifinyelela kanjani ekulayisheni ngokweqile kanye nokuvikelwa kwesekethe emfushane ngokusebenzisa izindlela zokugibela ezishisayo kazibuthe neze-elekthronikhi, ngokugxila okukhethekile ekwakhiweni okusha okulethweInkampani Yuye Electrical Co., Ltd.

Ukubaluleka Kokuvikela Isekethe

Ngaphambi kokuhlola izindlela ze-MCCBs, kubalulekile ukuqonda ukubaluleka kokuvikelwa kwesekethe. Ukugcwala ngokweqile kwenzeka lapho i-current egeleza kwisekethe idlula umthamo wayo olinganiselwe, okuholela ekukhiqizeni ukushisa okukhulu. Ngakolunye uhlangothi, izifunda ezimfushane zenzeka lapho kunendlela engalindelekile yokumelana okuphansi, okubangela ukuqhuma okungazelelwe kwamanje. Zombili lezi zimo zingaholela ekulimaleni kwemishini, izingozi zomlilo, ngisho nokulimala komuntu siqu. Ngakho-ke, izindlela zokuvikela ezisebenzayo zibalulekile ukuze kuvikelwe izinhlelo zikagesi.

Ikesi Elibunjiwe Izigebengu Zesekethe: Uhlolojikelele

I-circuit breaker yekesi elibunjiwe iyisisetshenziswa se-electromechanical esiphazamisa ukuhamba kukagesi uma kwenzeka ukulayisha ngokweqile noma isifunda esifushane. Asetshenziswa kakhulu ezimbonini, ezentengiselwano, nasezindaweni zokuhlala ngenxa yokuthembeka nokusebenziseka kalula. Ama-circuit breakers abunjiwe aklanyelwe ukuvula isekethe ngokuzenzakalelayo lapho kutholwa iphutha, ngaleyo ndlela avimbele ukulimala ohlelweni lukagesi.

I-Tripping Mechanism: Thermal Magnetic vs Electronic

Kunezindlela ezimbili eziyinhloko zokukhubeka ezisetshenziswa kuma-MCCB: i-thermal-magnetic ne-electronic. Indlela ngayinye inezici zayo eziyingqayizivele kanye nezinzuzo ezifaka isandla ekusebenzeni kahle kwe-circuit breaker.

I-Thermal Magnetic Trip Mechanism

Indlela yohambo lwe-thermal-magnetic ihlanganisa imisebenzi emibili ehlukene: ukuvikela okushisayo nokuvikela kazibuthe.

1. Ukuvikelwa kokushisa: Lesi sici sisekelwe kumgomo wokushisa okukhiqizwa ukuhamba kwamandla. I-MCCB iqukethe umugqa we-bimetallic ogoba lapho imanje igeleza kuwo. Lapho i-current idlula umkhawulo osethiwe isikhathi eside, umugqa we-bimetallic ugoba ngokwanele ukuze ugibele i-circuit breaker, iphazamise ukugeleza kwamanje. Lo mshini usebenza kahle kakhulu ekuvikeleni izimo zokugcwala ngokweqile.

2. Ukuvikela kazibuthe: Ingxenye kazibuthe yendlela kazibuthe eshisayo yakhelwe ukubhekana namasekhethi amafushane. Isebenzisa uzibuthe kagesi ukuze ikhiqize insimu kazibuthe ngokulingana namanje egeleza kusekethe. Lapho isifunda esifushane senzeka, lamanje likhuphuka ngokushesha, okwenza ukuthi inkambu kazibuthe ikhule kakhulu. Uma amandla kazibuthe edlula umkhawulo othile, enza kusebenze indlela yohambo, aphule isekethe futhi anikeze ukuvikeleka okusheshayo ephutheni.

Izindlela zokugibela ezishisayo-zibuthe zikhethwa ngenxa yobulula bazo, ukwethembeka kanye nokusebenza kahle kwezindleko.Inkampani Yuye Electric Co., Ltd.ubehamba phambili ekuthuthukiseni ama-MCCB asezingeni eliphezulu ozibuthe athuthukise ukusebenza nokuqina ukuze kuqinisekiswe ukuthi amasistimu kagesi ahlala evikelekile ngaphansi kwezimo eziningi ezahlukene.

I-Electronic Trip Mechanism

Uma kuqhathaniswa ne-thermal-magnetic mechanism, indlela yohambo lwe-elekthronikhi isebenzisa ugesi oseqophelweni eliphezulu ukuze iqaphe ukugeleza kwamanje kumjikelezo. Lo mshini unikeza izinzuzo ezimbalwa:

1. Inembile: Indlela yohambo lwe-elekthronikhi inikeza izilungiselelo ezinembe kakhulu nezilungisekayo kanye nokuvikela isiyingi esifushane. Abasebenzisi bangakwazi ukwenza ngokwezifiso izilungiselelo zohambo ngokuya ngezidingo ezithile zesistimu yabo kagesi.

2. Isivinini: Izindlela zokukhubeka zika-elekthronikhi zingathola amaphutha ngokushesha kakhulu kunamasistimu ezibuthe ezishisayo. Lesi sikhathi sokuphendula esisheshayo sibalulekile ekunciphiseni umonakalo phakathi nomcimbi wesifunda esifushane.

3. Izici ezengeziwe: Ama-MCCB amaningi e-electronic afakwe izici ezifana namakhono okuxhumana, anika amandla ukuqapha nokulawula kude. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza zezimboni lapho idatha yesikhathi sangempela ibalulekile ekugcineni ubuqotho besistimu.

Inkampani Yuye Electrical Co., Ltd.yamukele ukuthuthukiswa kwezindlela zokugibela zikagesi, ezihlanganisa ubuchwepheshe besimanje kumiklamo yayo ye-MCCB. Ama-circuit breaker ayo e-elekthronikhi aklanyelwe ukuhlinzeka ngokuvikeleka okuphakeme nokuzivumelanisa nezimo ukuze ahlangabezane nezidingo ezihlukahlukene zezinhlelo zikagesi zesimanje.

Izigebengu zesekhethi ezibunjiwe zidlala indima ebalulekile ekuqinisekiseni ukuphepha nokuthembeka kwezinhlelo zikagesi ngokuhlinzeka ngokugcwala okusebenzayo nokuvikelwa kwesekethe emfushane. Ukukhetha phakathi kwe-thermal-magnetic kanye ne-electronic tripping mechanisms kuncike ezidingweni ezithile zohlelo lokusebenza. I-Thermal-magnetic MCCBs inikeza ubulula nokuthembeka, kuyilapho ama-MCCB e-electronic anikeza ukunemba nezici ezithuthukile.

I-Yuye Electric Co., Ltd. ingumholi kulo mkhakha, ihlale isungula futhi ithuthukisa imikhiqizo yayo ye-circuit breaker ukuze ihlangabezane nezidingo eziguqukayo zemboni. Ngokuqonda izindlela ezingemuva kwama-circuit breakers abunjiwe, onjiniyela nochwepheshe bangenza izinqumo ezinolwazi ezithuthukisa ukuphepha nokusebenza kahle kwamasistimu kagesi. Njengoba ubuchwepheshe buqhubeka buthuthuka, ikusasa lokuvikelwa kwesekethe libukeka liqhakazile, futhi i-Yuye Electric Co., Ltd. ihamba phambili kulolu shintsho.
