Iyini inzuzo ye-MCB

Ama-Miniature Circuit Breakers (MCBs)yakhelwe ama-voltage e-DC alungele izinhlelo zokusebenza zokuxhumana kanye ne-photovoltaic (PV) DC izinhlelo.Ngokugxila okukhethekile ekusebenzeni nasekuthembekeni, lawa ma-MCB ahlinzeka ngohlu lwezinzuzo, ukubhekana nezinselele eziyingqayizivele ezilethwa izinhlelo zokusebenza eziqondile zamanje.Kusukela kuzintambo ezenziwe lula kuye kumandla kagesi anesilinganiso esiphezulu, izici zawo zihlangabezana nezidingo ezinembile zobuchwepheshe besimanje, okuzenza zibaluleke kakhulu ekuqinisekiseni ukuphepha nokusebenza kahle.Kulesi sihloko, sihlolisisa izinzuzo eziningi ezibeka lawa ma-MCB njengabadlali ababalulekile esimweni esiguqukayo sobunjiniyela bakagesi.

Idizayini Ekhethekile Yezicelo ze-DC

II-JCB3-63DC i-circuit breakerigqama ngedizayini yayo eyenzelwe wena, yakhelwe ngokucacile izinhlelo zokusebenza ze-DC.Lokhu okukhethekile kuqinisekisa ukusebenza okuseqophelweni eliphezulu nokuphepha ezindaweni lapho i-direct current iyinto evamile.Lo mklamo okhethekile uwubufakazi bokuvumelana nezimo kwe-circuit breaker, izulazula ngaphandle komthungo ubunkimbinkimbi bezindawo ze-DC.Ihlanganisa izici ezifana ne-non-polarity kanye nezintambo ezilula, eziqinisekisa inqubo yokufaka engenazo izinkinga.Amandla kagesi aphezulu afika ku-1000V DC afakazela amandla ayo aqinile, isici esibalulekile ekusingatheni izidingo zobuchwepheshe besimanje.I-JCB3-63DC circuit breaker ayigcini nje ngokuhlangabezana nezindinganiso zemboni;kuyawabeka, akhombisa ukuzibophezela okungaguquki ekusebenzeni kahle nokuphepha.Idizayini yayo, elungiselwe kahle i-solar, i-PV, indawo yokugcina amandla, nezinhlelo ezihlukahlukene ze-DC, iqinisa isikhundla sayo njengetshe legumbi ekuthuthukiseni izinhlelo zikagesi.

I-Non-Polarity kanye Nezintambo Ezilula

Esinye sezici ezigcizelelayo ze-MCB ukungeyona i-polarity eyenza inqubo yokufaka izintambo ibe lula.Lesi sici asigcini nje ngokuthuthukisa ukusebenzisana kahle komsebenzisi kodwa futhi sinomthelela ekwehliseni amaphutha ngesikhathi sokufakwa.

Amandla Amandla Kagesi Asezingeni Eliphezulu

Ngamandla kagesi alinganiselwe afika ku-1000V DC, lawa ma-MCB abonisa amandla aqinile, awenza akwazi ukuphatha izimfuno zamasistimu anamandla kagesi aphezulu e-DC avame ukutholakala kumanethiwekhi okuxhumana nokufakwa kwe-PV.

Amandla Okushintsha Okuqinile

Asebenza ngaphakathi kwemingcele ye-IEC/EN 60947-2, lawa ma-MCBs aqhosha ngomthamo wokushintsha onesilinganiso esiphakeme ongu-6 kA.Lesi sici siqinisekisa ukuthi i-circuit breaker ingakwazi ukuphatha ngokuthembekile imithwalo ehlukahlukene futhi iphazamise ngempumelelo ukugeleza kwamandla ngesikhathi sephutha.

I-Insulation Voltage kanye ne-Impuls Standstand

I-voltage engu-insulation (Ui) engu-1000V kanye ne-impulse elinganiselwe imelana ne-voltage (Uimp) engu-4000V igcizelela ikhono le-MCB lokumelana nezingcindezi zikagesi, ihlinzeka ngesendlalelo esingeziwe sokukhuthazela ezimeni ezihlukahlukene zokusebenza.

Ikilasi Lamanje Lokukhawulela 3

Ahlukaniswa njengedivayisi yamanje ekhawulelayo Yekilasi 3, lawa ma-MCB ahamba phambili ekwehliseni umonakalo ongaba khona uma kwenzeka iphutha.Leli khono libalulekile ekuvikeleni izisetshenziswa ezansi nomfula kanye nokugcina ubuqotho besistimu kagesi.

I-Selective Back-up Fuse

Ifakwe i-fuse yesipele ebonisa ukukhetha okuphezulu, lawa ma-MCB aqinisekisa amandla aphansi okuvumela.Lokhu akugcini nje ngokuthuthukisa ukuvikelwa kwesistimu kodwa futhi kunomthelela ekuthembekeni okuphelele kokusethwa kukagesi.

Inkomba Yendawo Yokuxhumana

Inkomba yendawo yokuxhumana ebomvu-luhlaza esebenziseka kalula inikeza isignali ebonakalayo ecacile, ekuvumela ukuthi uqaphe kalula isimo somephuli.Lesi sici esilula kodwa esisebenzayo sengeza isendlalelo esengeziwe sokusebenziseka kalula kuma-opharetha.

Ibanga Elibanzi Lama-currents alinganiselwe

Lawa ma-MCB amukela izinhlobonhlobo zamaza okulinganisa, anezinketho ezifinyelela ku-63A.Lokhu kuvumelana nezimo kuzenza zikwazi ukuhlangabezana nezidingo zomthwalo ezihlukene zezinhlelo zokusebenza ezihlukene, okwengeza ukuguquguquka ekusetshenzisweni kwazo.

Ukucushwa Kwesigxobo Esihlukahlukene

Atholakala ku-1 Pole, 2 Pole, 3 Pole, kanye ne-4 Pole ukulungiselelwa, lawa ma-MCB abhekelela ukuhlukahluka kokusetha kwesistimu.Lokhu kuhlukahluka kuwusizo ekuzivumelaniseni nezidingo ezithile zokufakwa kukagesi okuhlukile.

Izilinganiso zamandla kagesi zezigxobo ezihlukene

Izilinganiso zamandla kagesi ezifanelanisiwe zokumiswa kwezigxobo ezihlukene - 1 Pole=250Vdc, 2 Pole=500Vdc, 3 Pole=750Vdc, 4 Pole=1000Vdc - zibonisa ukuguquguquka kwezimo kwalawa ma-MCB ezidingweni zamandla kagesi ahlukahlukene.

Ukuhambisana ne-Standard Busbars

I-MCB breaker yakhelwe ukuhlanganisa ngaphandle komthungo namabhasi ajwayelekile e-PIN kanye ne-Fork.Lokhu kuhambisana kwenza kube lula inqubo yokufaka futhi kusiza ukufakwa kwazo kumasethingi kagesi akhona.

Idizayinelwe Isitoreji Solar Nezamandla

Ukuguquguquka kwebhokisi lensimbi le-MCB kuphinde kugqanyiswe idizayini yabo ecacile yelanga, i-PV, indawo yokugcina amandla, nezinye izinhlelo zokusebenza ze-DC.Njengoba umhlaba wamukela imithombo yamandla avuselelekayo, lezi zigelekeqe zivela njengezingxenye ezibalulekile ekuqinisekiseni ukwethembeka nokuphepha kwalezo zinhlelo.

Umugqa Ongezansi

Izinzuzo ze-aI-Miniature Circuit Breaker (MCB)idlulela ngalé komklamo wabo okhethekile.Kusukela kuzinhlelo zokusebenza ze-DC ezikhethekile kuye ezicini ezisebenziseka kalula, lawa ma-MCB abeka amazinga amasha okuphepha nokusebenza kahle.Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ama-circuit breaker angokuqina, avikela ubuqotho bezinhlelo zokuxhumana kanye nokufakwa kwe-PV ngamakhono azo angenakuqhathaniswa.Umshado wokuqamba izinto ezintsha nokuthembeka kulawa ma-MCB uwagcina njengezimpahla ezibalulekile endaweni ekhula njalo yobunjiniyela bakagesi.
