Ukuqonda i-Overload kunye noKhuseleko lweSekethe emifutshane kwi-Molded Case Circuit Breakers: Indima ye-Thermal Magnetic kunye ne-Electronic Tripping Mechanisms

Kwintsimi yobunjineli bombane, ukhuseleko kunye nokuthembeka kweenkqubo zombane kubaluleke kakhulu. Enye yezinto eziphambili eziqinisekisa olu khuseleko yi-molded case circuit breaker (MCCB). Ezi zixhobo zenzelwe ukukhusela iisekethe kwi-overloads kunye neesekethe ezimfutshane ezinokubangela ukusilela kunye nobungozi. Eli nqaku lijonga nzulu kwindlela abaphuli beesekethe ezibunjiweyo bafikelela ngayo kumthwalo ogqithisiweyo kunye nokhuseleko olufutshane lwesekethe ngokusebenzisa iindlela zokuhamba ngemagnethi kunye ne-elektroniki, kugxilwe ngokukodwa kwizinto ezintsha eziziswaI-Yuye Electrical Co., Ltd.

Ukubaluleka koKhuseleko lweSekethe

Ngaphambi kokuphonononga iindlela ze-MCCBs, kubalulekile ukuqonda ukubaluleka kokhuseleko lwesekethe. Ukulayisha ngaphezulu kwenzeka xa i-current equkuqela kwisekethe idlula umthamo wayo olinganisiweyo, okukhokelela ekuveliseni ubushushu obugqithisileyo. Ngakolunye uhlangothi, iisekethe ezimfutshane zenzeke xa kukho indlela engalindelekanga yokuchasana, ebangela ukuqhuma ngokukhawuleza kwangoku. Zombini ezi meko zinokukhokelela kumonakalo wezixhobo, iingozi zomlilo, kunye nokwenzakala komntu. Ngoko ke, iindlela zokukhusela ezisebenzayo zibalulekile ekukhuseleni iinkqubo zombane.

I-Molded Case Circuit Breakers: Isishwankathelo

I-molded case circuit breaker sisixhobo se-electromechanical esiphazamisa ukuhamba kombane xa kwenzeka ukugqithisa okanye isiphaluka esifutshane. Zisetyenziswa ngokubanzi kwimizi-mveliso, urhwebo, kunye nezicelo zokuhlala ngenxa yokuthembeka kunye nokusebenziseka ngokulula. Ii-breakers zesekethe ezibunjiweyo zenzelwe ukuvula ngokuzenzekelayo isiphaluka xa kufunyenwe impazamo, ngaloo ndlela ikhusela umonakalo kwinkqubo yombane.

I-Tripping Mechanism: Thermal Magnetic vs Electronic

Kukho iindlela ezimbini eziphambili zokukhwela ezisetyenziswa kwii-MCCBs: i-thermal-magnetic kunye ne-elektroniki. Indlela nganye ineempawu zayo ezizodwa kunye neenzuzo ezifaka isandla ekusebenzeni kakuhle kwe-breaker circuit.

Thermal Magnetic Trip Mechanism

Indlela yohambo lwe-thermal-magnetic idibanisa imisebenzi emibini eyahlukeneyo: ukukhuselwa kwe-thermal kunye nokukhusela magnetic.

1. Ukukhuselwa kwe-Thermal: Olu phawu lusekelwe kumgaqo wokushisa owenziwe ngokuhamba kwangoku. I-MCCB iqulethe i-bimetallic strip egoba xa ikhoyo ngoku ihamba kuyo. Xa i-current idlula umda obekiweyo ixesha elide, i-bimetallic strip igoba ngokwaneleyo ukuba ihambe i-breaker circuit, iphazamise ukuhamba kwangoku. Lo matshini usebenza ngokukodwa ekukhuseleni kwiimeko zokugcwala.

2. Ukhuseleko lwemagnethi: Icandelo lemagnethi lemagnethi ye-thermal yenzelwe ukujongana neesekethe ezimfutshane. Isebenzisa umazibuthe we-electromagnetic ukuvelisa intsimi yamagnetic ngokulungeleleneyo nokuqukuqela kwangoku kwisekethe. Xa isiphaluka esifutshane senzeke, ukunyuka kwangoku kuhamba ngokukhawuleza, kubangela ukuba intsimi yamagnetic inyuke kakhulu. Xa amandla amagnetic edlula umda othile, avule indlela yohambo, aphule isiphaluka kwaye anike ukhuseleko olukhawulezayo kwisiphoso.

Iindlela zokukhwela i-Thermal-magnetic zikhethwa ngenxa yokulula kwazo, ukuthembeka kunye nokusebenza kakuhle kweendleko.I-Yuye Electric Co., Ltd.ibihamba phambili ekuphuhliseni ii-MCCB ze-thermal-magnetic eziphucule ukusebenza kunye nokuqina ukuqinisekisa ukuba iinkqubo zombane zihlala zikhuselwe phantsi koluhlu olubanzi lweemeko.

Inkqubo yohambo lwe-elektroniki

Xa kuthelekiswa nomatshini we-thermal-magnetic, indlela yohambo lwe-elektroniki isebenzisa i-elektroniki ephucukileyo ukujonga ukuqukuqela kwangoku kwisekethe. Lo matshini ubonelela ngeenzuzo ezininzi:

1. Ngokuchanekileyo: Inkqubo yohambo lwe-elektroniki ibonelela ngokuchaneka ngakumbi kunye nokulungelelaniswa komthwalo ogqithisiweyo kunye nokhuseleko lwesekethe emfutshane. Abasebenzisi banokwenza ngokwezifiso izicwangciso zohambo ngokweemfuno ezithile zenkqubo yabo yombane.

2. Isantya: Iindlela zokukhubeka nge-elektroniki zinokubona iimpazamo ngokukhawuleza kuneenkqubo zemagnetic ze-thermal. Eli xesha lokuphendula ngokukhawuleza libalulekile ekunciphiseni umonakalo ngexesha lesiganeko esifutshane.

3. Iimpawu ezongezelelweyo: Ii-MCCB ezininzi ze-elektroniki zixhotyiswe ngeempawu ezifana nezakhono zokunxibelelana, ezivumela ukubeka iliso kunye nokulawula kude. Oku kubaluleke kakhulu kwizicelo zemizi-mveliso apho idatha yexesha langempela ibaluleke kakhulu ekugcineni ukuthembeka kwenkqubo.
