Niki inyungu za Mcb

Mininiature Abamenaho Umuzunguruko (MCBS)Yagenewe DC voltage ya DC nibyiza kubisabwa mu itumanaho na PhotoVeltaic (PV) sisitemu ya DC. Hamwe n'ibanze yihariye ku bushakashatsi no kwizerwa, izi mcb zitanga inyungu zitandukanye, zivuga ibibazo bidasanzwe bibaye muburyo butaziguye. Kuva ku ndumiro yoroshye kugeza ku bushobozi bwo hejuru, ibiranga ubuhanga bukenewe mu ikoranabuhanga rigezweho, bigatuma ntaharazwa mu kubungabunga umutekano no gukora neza. Muri iki kiganiro, dusuzume ibyiza byinshi ushyira muri MCbs nkabakinnyi bakomeye mubice bihumura neza byubwubatsi byamashanyarazi.

Igishushanyo mbonera cya DC Porogaramu

TheJCB3-63DC Kumena umuzungurukoigaragara hamwe nigishushanyo cyacyo gihumanye, cyakozwe neza kubisaba DC. Iyi yihariye iremeza imikorere hamwe numutekano mubidukikije aho hatangwa ibisanzwe. Iki gishushanyo cyihariye ni Isezerano kumurimo wumuzunguruko, uvanaho neza interricacies yibidukikije bya DC. Irimo ibiranga nkibidafite amayeri no kwibira byoroshye, kureba inzira yo kwishyiriraho happle. VULTGEGE YISUMBUYE YATANZWE DC ya 1000v kugeza ku nyungu zikomeye zayo, ikintu gikomeye mugukemura ibyifuzo byubuhanga bugezweho. JCB3-63DC Kumena umuzunguruko ntibihuza ibipimo ngenderwaho; Irabishyiramo, kwerekana ubwitange butajegajega kugirango imikorere n'umutekano. Igishushanyo cyacyo, gihuza neza nizuba, pv, kubika ingufu, hamwe nibisabwa bitandukanye bya DC, bishimangira umwanya wabyo nkikomeza ifumbire mugutezimbere sisitemu z'amashanyarazi.

Intungane kandi yoroshye cyane

Kimwe mu bintu biranga MCB ni umusomyi wabo byoroshya inzira yo gucuranga. Ibi biranga ntabwo byongera abakoresha-ubucuti ahubwo binagira uruhare mugutaka mugihe cyo kwishyiriraho.

Ubushobozi bwo hejuru bwa voltage

Hamwe na voltage yatanzwe na 1000v DC kugeza 1000v, izi mcb zerekana ubushobozi bukomeye, ubashoboze gukemura ibyifuzo bya DC ya volut-voltage binini bikunze kuboneka mumiyoboro itumanaho hamwe na PV.

Ubushobozi bwo guhinduranya

Gukorera mubipimo bya IEC / EN 60947-2, izi mcb zirata ubushobozi bwo guhinduranya 6 KA. Iyi mikorere iremeza ko kumena umuzunguruko bishobora kwizerwa kwizerwa imizigo itandukanye kandi ihagarika ingendo yibintu mugihe cyamakosa.

Kumenyesha voltage na impulse

Ibishushanyo mbonera (UI) bya 1000v na Impulse yafashwe ihanganye na voltage (UIMP) ya 4000V Shyira ahagaragara ubushobozi bwa MCB bwo guhangana n'imihangayiko y'amashanyarazi, itanga urwego rwo kwihangana mu buryo butandukanye.

Ikigezweho

Byashyizwe ahagaragara nkicyiciro cya metero 3, izi mcbs nziza mu kugabanya ibyangiritse mugihe habaye amakosa. Ubu bushobozi ni ngombwa mukingira ibikoresho byayoroka no gukomeza ubusugire bwa sisitemu y'amashanyarazi.

Guhitamo inyuma-up fuse

Ifite ibikoresho inyuma-up fuse irimo uburyo bworoshye, izi mcb zemeza ko zitunze. Ibi ntabwo byongera uburinzi bwa sisitemu gusa ahubwo binatanga umusanzu mubibazo rusange byamashanyarazi.

Contact

Umukoresha-winshuti-icyatsi-icyatsi conty contestor itanga ikimenyetso cyerekana ibimenyetso byerekana, bikagutera gukurikirana byoroshye imiterere ya breaker. Ibi bintu byoroshye ariko bifite akamaro byongeraho uburyo bworoshye bworoshye abakora.

Ubwoko butandukanye bwimiyoboro

Izi mcbs yakira urutonde rutandukanye rwimigezi, hamwe namahitamo agera kuri 63a. Ibi guhinduka bibafasha kuzuza ibisabwa bitandukanye bya porogaramu zitandukanye, ongeraho guhuza ibikorwa byabo.

Iboneza rya VILE

Kuboneka muri pole 1, pole 2, pole 3, hamwe nubukorikori 4, iyi mcb ihuza uburyo butandukanye bwa sisitemu. Ubu buryo butandukanye bufite ibikoresho muguhuza ibyifuzo byihariye byibikoresho bitandukanye byamashanyarazi.

Ibipimo bya voltage kumiti itandukanye

Ibishushanyo mbonera bya volutge kubibo bitandukanye bya pole - 1 Pole = 250vDC, 550vDC, 550vDC, 150vDC Ibisabwa muri MCBS kubisabwa bitandukanye.

Guhuza na busbars isanzwe

Kumena MCB byateguwe kugirango bihuze na pin na pin na for Ubwoko bwa Busbars isanzwe. Ubu buryo bwo gushimangira inzira yo kwishyiriraho no korohereza insups zabo mumashanyarazi ariho.

Yagenewe kubika izuba no kubika ingufu

Ibisobanuro bya MCB agasanduku ka MCB biragaragara neza kubishushanyo byabo bisobanutse byizuba, PV, kubika ingufu, nibindi bikorwa bya DC. Nkuko isi ikubiyemo ingufu zishobora kuvugururwa, aba bahungu bahazunguruko bagaragara nkikigereranyo cyingenzi mugushidikanya ko kwizerwa n'umutekano wa sisitemu.

Umurongo wo hasi

Ibyiza bya aMininiature Kumena (MCB)Kurenze kure igishushanyo mbonera. Kuva kuri porogaramu yihariye ya DC kubiranga abakoresha, izi mcb zishyiraho ibipimo bishya mumutekano no gukora neza. Mugihe ikoranabuhanga rikomeje gutera imbere, abo mu bazunguruko ni igikona, kurengera ubusugire bwa sisitemu yo gutumanaho na PV bishyira hamwe nubushobozi bwabo butagereranywa. Ubukwe bwo guhanga udushya no kwizerwa muri iyi mcb Komeza nk'umutungo w'imitungo ntarengwa mu buryo bwagutse cyane mu mashanyarazi.
