Ubwino wa MCB ndi chiyani?

Ma Miniature Circuit Breakers (MCBs)zopangidwira ma voltages a DC ndizoyenera kugwiritsa ntchito makina olumikizana ndi ma photovoltaic (PV) DC. Poyang'ana kwambiri kuchitapo kanthu komanso kudalirika, ma MCB awa amapereka maubwino angapo, kuthana ndi zovuta zapadera zomwe zimadza chifukwa chakugwiritsa ntchito mwachindunji. Kuchokera pa mawaya osavuta kupita ku mphamvu yamagetsi okwera kwambiri, mawonekedwe ake amakwaniritsa zosowa zenizeni zaukadaulo wamakono, zomwe zimawapangitsa kukhala ofunikira kwambiri pakuwonetsetsa chitetezo komanso kuchita bwino. Munkhaniyi, tikuwona zabwino zambiri zomwe zimayika ma MCB awa ngati omwe akutenga nawo gawo pakukula kwaukadaulo wamagetsi.

Mapangidwe apadera a DC Applications

TheJCB3-63DC wowononga deraimawonekera bwino ndi kapangidwe kake kopangidwira, kopangidwira bwino ntchito za DC. Kukhazikika kumeneku kumapangitsa kuti magwiridwe antchito azikhala bwino komanso chitetezo m'malo omwe chiwongolero chilipo. Kapangidwe kapadera kameneka ndi umboni wa kusinthasintha kwa woyendetsa dera, kuyang'ana mosasunthika zovuta zamadera a DC. Zimaphatikizapo zinthu monga zopanda polarity ndi mawaya osavuta, kuonetsetsa kuti palibe vuto loyika. Magetsi okwera kwambiri mpaka 1000V DC amatsimikizira mphamvu zake, chinthu chofunikira kwambiri pakukwaniritsa zofunikira zaukadaulo wamakono. The JCB3-63DC wosweka dera samangokwaniritsa miyezo makampani; zimawakhazikitsa, kusonyeza kudzipereka kosasunthika pakuchita bwino ndi chitetezo. Mapangidwe ake, okonzedwa bwino a solar, PV, yosungirako mphamvu, ndi ntchito zosiyanasiyana za DC, amalimbitsa udindo wake monga mwala wapangodya pakupititsa patsogolo magetsi.

Non-Polarity ndi Mawaya Osavuta

Chimodzi mwazofunikira za MCB ndi kusakhala kwa polarity komwe kumathandizira njira yolumikizira waya. Khalidweli silimangowonjezera kuyanjana kwa ogwiritsa ntchito komanso limathandizira kuchepetsa zolakwika pakuyika.

High Rated Voltage Kutha

Ndi ma voliyumu ovotera mpaka 1000V DC, ma MCB awa amawonetsa mphamvu zolimba, zomwe zimawathandiza kuthana ndi zofunikira zamakina othamanga kwambiri a DC omwe amapezeka pamanetiweki olumikizirana ndi ma PV.

Kusintha Kwamphamvu Kwambiri

Kugwira ntchito mkati mwa magawo a IEC/EN 60947-2, ma MCB awa amadzitamandira kuti amatha kusintha kwambiri 6 kA. Izi zimatsimikizira kuti woyendetsa dera amatha kunyamula katundu wosiyanasiyana ndikusokoneza bwino kayendedwe ka pano pakachitika vuto.

Insulation Voltage ndi Impulse Kupirira

Mphamvu yamagetsi yamagetsi yamagetsi (Ui) ya 1000V ndi mphamvu yamphamvu yopirira (Uimp) ya 4000V imatsimikizira kuthekera kwa MCB kupirira kupsinjika kwamagetsi, zomwe zimapatsa mphamvu yowonjezereka mumayendedwe osiyanasiyana.

Class 3 yochepetsa malire

Zodziwika ngati zida zochepetsera Class 3 pakadali pano, ma MCB awa amapambana pochepetsa kuwonongeka komwe kungachitike pakachitika vuto. Kuthekera kumeneku ndikofunikira pakuteteza zida zotsika ndikusunga kukhulupirika kwamagetsi.

Selective Back-Up Fuse

Zokhala ndi fuse yobwerera kumbuyo yokhala ndi kusankha kwakukulu, ma MCB awa amawonetsetsa kutsika kwamphamvu. Izi sizimangowonjezera chitetezo chadongosolo komanso zimathandizira kudalirika kwathunthu kwa kukhazikitsa magetsi.

Contact Position Indicator

Chizindikiro cholumikizana ndi chobiriwira chobiriwira chosavuta kugwiritsa ntchito chimapereka chizindikiro chowoneka bwino, kukulolani kuti muwone momwe woswekayo alili. Chosavuta koma chothandizachi chimawonjezera mwayi wowonjezera kwa ogwiritsa ntchito.

Mitundu Yambiri Yomwe Adavotera

Ma MCB awa amakhala ndi mafunde osiyanasiyana ovotera, ndi zosankha zomwe zimafikira 63A. Kusinthasintha kumeneku kumawathandiza kuti akwaniritse zofunikira zosiyanasiyana zamapulogalamu osiyanasiyana, ndikuwonjezera kusinthasintha kwazomwe zimagwiritsidwa ntchito.

Zosintha Zosiyanasiyana za Pole

Zilipo mu 1 Pole, 2 Pole, 3 Pole, ndi 4 Pole masinthidwe, ma MCB awa amakwaniritsa makhazikitsidwe osiyanasiyana. Kusinthasintha kumeneku kumathandizira kuti zigwirizane ndi zosowa zenizeni zamitundu yosiyanasiyana yamagetsi.

Mavoti a Voltage pamitengo Yosiyanasiyana

Ma voliyumu ogwirizana ndi masinthidwe osiyanasiyana - 1 Pole = 250Vdc, 2 Pole = 500Vdc, 3 Pole = 750Vdc, 4 Pole = 1000Vdc - akuwonetsa kusinthasintha kwa ma MCB awa kumitundu yosiyanasiyana yamagetsi.

Kugwirizana ndi Standard Busbars

Chophwanyira cha MCB chapangidwa kuti chiphatikize bwino ndi ma PIN onse amtundu wa Fork mabasi. Kugwirizana kumeneku kumawongolera njira yoyika ndikuwongolera kuphatikizidwa kwawo pamakonzedwe amagetsi omwe alipo.

Zopangidwira Zosungirako za Dzuwa ndi Mphamvu

Kusinthasintha kwa bokosi lachitsulo la MCB kumawonekeranso ndi kapangidwe kawo ka solar, PV, yosungirako mphamvu, ndi ntchito zina za DC. Pamene dziko lapansi likukumbatira magwero a mphamvu zongowonjezwdwa, zowononga maderawa zimatuluka ngati zinthu zofunika kwambiri pakuwonetsetsa kudalirika ndi chitetezo cha machitidwe otere.

Pansi Pansi

Ubwino wa aMiniature Circuit Breaker (MCB)amapitilira kupitilira mapangidwe awo okha. Kuchokera pamapulogalamu apadera a DC kupita ku mawonekedwe ake osavuta kugwiritsa ntchito, ma MCB awa akukhazikitsa miyezo yatsopano pachitetezo ndi magwiridwe antchito. Pomwe ukadaulo ukupitilirabe patsogolo, ophwanya madera ndi olimba, kuteteza kukhulupirika kwa njira zoyankhulirana ndi kukhazikitsa kwa PV ndi kuthekera kwawo kosayerekezeka. Ukwati waluso komanso kudalirika mu ma MCB awa amawasunga ngati zinthu zofunika kwambiri pakukula kwaukadaulo wamagetsi.
