I-Acereare Electric entsha ye-ARM5 yochungechunge lwekhefu eliphindwe kabili le-plastic-case breaker
I. Uhlolojikelele lomkhiqizo
Uchungechunge lwe-ARM5 olubunjwe ngecala eliphindwe kabili le-breaker circuit luwumkhiqizo omusha osanda kuthuthukiswa yinkampani yethu. Idizayini yayo ikhombisa umgomo wakamuva wamanje wokukhawulela kanye nobuchwepheshe bokukhiqiza, futhi inezici ezihlangene, ezimodulayo, zokuphuka okuphezulu, i-zero arcing, eziluhlaza kanye nezici zokuvikela imvelo. I-circuit breaker ifanele isekethe ye-AC 50Hz/60Hz ene-voltage elinganisiwe ye-insulation engu-1000V, i-voltage esebenza kakhulu elinganiselwe engu-690V, umthamo omkhulu wokuphuka we-icu nama-ics afika ku-200kA futhi akalwe okwamanje ukusuka ku-32A kuya ku-630A ukwenza, ukuphuka nokuthwala amandla amanje alinganiselwe, futhi ingavikela ngokuthembekile izintambo kanye nempahla kagesi uma kwenzeka kugcwala kakhulu, isifunda esifushane kanye ne-undervoltage. Ingase futhi isetshenziselwe ukuqala okungajwayelekile, ukulayisha ngokweqile, ukujikeleza okufushane kanye nokuvikelwa kwe-undervoltage yemoto.
II. Izinzuzo zomkhiqizo/amaphuzu okuthengisa
1. Uchungechunge lwe-ARM5 luye lwathuthukisa nakakhulu ukuthembeka kokunikezwa kwamandla, futhi lunezinzuzo zokumodularization, usayizi omncane, umthamo wokuphuka okuphezulu, i-arcing emfushane, ukwethembeka okuphezulu, ukuvikelwa kwemvelo okuhle, imisebenzi ebanzi, njll.
2. umthamo wokuphuka kwesiyingi esifushane ku-AC400V, uhlobo lwe-L: 100KA, uhlobo lwe-M: 150KA, uhlobo lwe-H: 200KA. I-100KA isetshenziselwa izinhlelo zokusebenza ezinezidingo eziphezulu zokusebenza, imigqa yokukhiqiza yezimboni, kanye nemishini kagesi ebalulekile. I-150KA-200KA inamandla okuphuka ahamba phambili embonini futhi ingasetshenziswa embonini esindayo kanye nezimboni ezikhethekile.
3. Lolu chungechunge lwezesekeli lungafakwa kalula endaweni ehambisanayo ye-breaker circuit futhi lube nokusebenza okuthembekile okusebenzayo. Ukukhishwa kwe-shunt, ukukhishwa kwe-undervoltage kanye nokuxhumana okuyisizayo konke kwenziwa amamojula ahlukene.
4. Ukukhishwa kazibuthe okushisayo kwe-ARM5-160, 250, 400 kanye nama-630 ama-circuit breaker kungalungiswa ukuze kuhlangatshezwane nezidingo zokuvikela.
Ⅲ. Khipha incazelo yemodeli
D: Ukuvikelwa kokusabalalisa amandla; MA: ukuvikelwa kwezimoto
Ikalwe okwamanje
TM: ukukhululwa kwe-thermomagnetic
Isilungiselelo sokuvikela ukulayisha ngokweqile siyalungiseka 1, futhi inani lokusetha lokuvikela isifunda esifushane liyalungiseka noma lilungiswe 2;

Imisebenzi esemqoka nezici
I. Idivayisi yokuvikela umoya
Lapho isifunda siphuka ngamandla amakhulu, igesi elisebhokisini leyunithi yokuxhumana licindezelwa ngokushesha, futhi idivayisi yokuvikela umoya womoya ishintsha ngokushesha i-latch yokusebenza ngaphansi kokucindezela komoya okuqinile, kunciphisa kakhulu umonakalo wokuphuka kwamanje kwezinye izingxenye zikagesi namabhasi.
Idizayini ye-Magnetic blow:yamanje igeleza ngokuthintana okugxilile ukuze ikhiqize umthombo we-electromagnetic, okwenza i-arc magnetic field arc ene-iron core futhi ingene ngokushesha ekamelweni lokucisha i-arc ngaphansi kwesenzo sensimu kazibuthe, evumela ukuthi iphule ngokushesha okwamanje.
Idizayini yesakhiwo enengqondo yabathintwayo abahambayo nabagxilile yenza inani eliphakeme lesekethe emfushane namandla alolu chungechunge lwemikhiqizo libe lincane kakhulu kunokulindelekile.
Isimiso sokusebenza: i-current igeleza isuka kothintana naye ohleliwe 1, igeleza isuka kothintana naye ohleliwe 2 ngokusebenzisa othintana naye wesiliva onyakazayo, ongaguquki kanye nothintana naye onyakazayo. Othintana naye onyakazayo unqamula ngokushesha ngaphansi kwesenzo samandla kagesi anamandla wokudonsa (i-Holm force kanye ne-Lorentz force) ukuze kuthuthukiswe isivinini sokuphuka.
Idizayini yokuphefumula komoya: lapho isifunda esikhulu esifushane senzeka kumjikelezo, izingxenye ezikhiqiza igesi zizokhiqiza enye igesi ngaphansi kwezinga lokushisa eliphakeme le-arc, umfutho womoya ebhokisini leyunithi yokuxhumana ukhula ngokushesha, futhi ukugeleza komoya okunesivinini kwakhiwe nge-outlet yomoya yegumbi lokucima i-arc, elingacisha ngokuphumelelayo i-arc.
