Ni izihe nyungu za MCB

Miniature yamashanyarazi (MCBs)yagenewe amashanyarazi ya DC nibyiza mubisabwa mu itumanaho na sisitemu ya DC. Hamwe nokwibanda kubikorwa bifatika no kwizerwa, izi MCBs zitanga inyungu zinyuranye, zikemura ibibazo byihariye biterwa nibisabwa byubu. Kuva insinga zoroheje kugeza ku bushobozi buke bwa voltage ubushobozi, imiterere yabyo ijyanye nibyifuzo bikenewe byikoranabuhanga rigezweho, bigatuma biba ngombwa mukurinda umutekano no gukora neza. Muri iki kiganiro, turacukumbura ibyiza byinshi bishyira MCBs nkabakinnyi bakomeye muguhindagurika kwimiterere yamashanyarazi.

Igishushanyo cyihariye cya DC Porogaramu

UwitekaJCB3-63DC kumena inzitiziigaragara hamwe nigishushanyo cyayo cyateguwe, cyakozwe neza kubikorwa bya DC. Iyi mikorere itanga imikorere myiza n'umutekano mubidukikije aho bigezweho ni bisanzwe. Igishushanyo cyihariye nubuhamya bwumuzunguruko wumuzunguruko uhuza n'imiterere, kugendagenda neza muburyo bukomeye bwibidukikije bya DC. Ikubiyemo ibintu nka non-polarite hamwe nogukoresha byoroshye, byemeza uburyo bwo kwishyiriraho ibibazo. Umuvuduko mwinshi wa voltage igera kuri 1000V DC yerekana ubushobozi bwayo bukomeye, ikintu cyingenzi mugukemura ibyifuzo byikoranabuhanga rigezweho. Imashanyarazi ya JCB3-63DC ntabwo yujuje ubuziranenge bwinganda; irabashyiraho, ikagaragaza ubwitange budahwema gukora neza n'umutekano. Igishushanyo cyacyo, gihujwe neza nizuba, PV, kubika ingufu, hamwe na DC zitandukanye, bishimangira umwanya wacyo nkibuye rikomeza imfuruka mugutezimbere amashanyarazi.

Non-Polarity and Wiring Simply Wiring

Kimwe mu bimenyetso biranga MCB ni ukutagira polarite yoroshya inzira yo gukoresha. Ibi biranga ntabwo byongera abakoresha-inshuti gusa ahubwo binagira uruhare mukugabanya amakosa mugihe cyo kwishyiriraho.

Ubushobozi Bukuru Buringaniye

Hamwe na voltage yagereranijwe kugera kuri 1000V DC, izi MCBs zigaragaza ubushobozi bukomeye, bubafasha gukemura ibyifuzo bya sisitemu ya voltage nini ya DC ikunze kuboneka mumiyoboro y'itumanaho no gushyiramo PV.

Ubushobozi bukomeye bwo guhindura

Gukorera mubipimo bya IEC / EN 60947-2, izi MCB zirata ubushobozi bwo guhinduranya cyane bwa 6 kA. Iyi mikorere iremeza ko kumena inzitizi bishobora kwizerwa neza imitwaro itandukanye kandi bigahagarika neza imigendekere yumuyaga mugihe cyamakosa.

Umuvuduko w'amashanyarazi hamwe na Impulse kwihanganira

Umuvuduko ukabije w'amashanyarazi (Ui) wa 1000V hamwe na impulse zapimwe zihanganira voltage (Uimp) ya 4000V bishimangira ubushobozi bwa MCB bwo guhangana n'umuvuduko w'amashanyarazi, bigatanga urwego rwinyongera rwo guhangana mubikorwa bitandukanye.

Kugabanya icyiciro cya 3

Bishyizwe mubikorwa bigabanya ibikoresho byo mucyiciro cya 3, izi MCBs nziza cyane mukugabanya ibyangiritse mugihe habaye amakosa. Ubu bushobozi ni ngombwa mu kurinda ibikoresho byo hasi no gukomeza ubusugire bwa sisitemu y'amashanyarazi.

Guhitamo Inyuma-Hejuru Fuse

Bifite ibikoresho byinyuma-fuse byerekana guhitamo kwinshi, izi MCBs zitanga imbaraga nke zo kurekura. Ibi ntabwo byongera sisitemu yo kurinda gusa ahubwo binagira uruhare muburyo rusange bwo kwizerwa kwamashanyarazi.

Menyesha Ikibanza

Umukoresha-nshuti itukura-icyatsi kiboneka cyerekana ibimenyetso byerekana ibimenyetso bigaragara, bigufasha gukurikirana byoroshye kumena. Iyi mikorere yoroshye ariko ikora neza yongeramo urwego rwinyongera kubakoresha.

Urwego runini rw'imigezi yagenwe

Izi MCBs zakira urwego rutandukanye rwimiyoboro yagenwe, hamwe namahitamo agera kuri 63A. Ihinduka ribafasha kuzuza ibisabwa bitandukanye byimitwaro ya porogaramu zitandukanye, wongeyeho byinshi mubikorwa byabo.

Iboneza rya Pole

Biboneka muri 1 Pole, 2 Pole, 3 Pole, na 4 Pole iboneza, izi MCBs zihura na sisitemu zitandukanye. Iyi mpinduramatwara ningirakamaro muguhuza ibyifuzo byihariye byamashanyarazi atandukanye.

Umuvuduko wa voltage kuri pole zitandukanye

Ibipimo bya voltage byateganijwe kuboneza rya pole zitandukanye - 1 Pole = 250Vdc, 2 Pole = 500Vdc, 3 Pole = 750Vdc, 4 Pole = 1000Vdc - herekana guhuza izi MCBs nibisabwa na voltage zitandukanye.

Guhuza na Busbars zisanzwe

Imashini ya MCB yashizweho kugirango ihuze hamwe na PIN na Fork yo mu bwoko bwa busbars. Uku guhuza byoroshya inzira yo kwishyiriraho kandi byorohereza kubishyira mumashanyarazi ariho.

Yashizweho Kubika izuba hamwe ningufu

Ubwinshi bwicyuma MCB agasanduku karushijeho kugaragazwa nigishushanyo mbonera cyizuba, PV, kubika ingufu, nibindi bikorwa bya DC. Mugihe isi yakira amasoko yingufu zishobora kuvugururwa, ibyo byuma byumuzunguruko bigaragara nkibice byingenzi mugukomeza kwizerwa numutekano wa sisitemu.

Umurongo w'urufatiro

Ibyiza bya aKumena Miniature Kumena (MCB)irenze kure igishushanyo cyabo cyihariye. Kuva porogaramu yihariye ya DC kugeza kubakoresha-nshuti zabo, izi MCBs zishyiraho ibipimo bishya mumutekano no gukora neza. Mugihe ikoranabuhanga rikomeje gutera imbere, abamena imirongo ni stalwarts, barinda ubusugire bwa sisitemu yitumanaho nibikoresho bya PV hamwe nubushobozi bwabo butagereranywa. Ubukwe bwo guhanga udushya no kwizerwa muri izi MCBs bikomeza kuba umutungo wingenzi mubice bigenda byiyongera mubikorwa byubwubatsi bwamashanyarazi.
