115V920Ah DC Power System
Chanindi DC Power System?
Dongosolo lamagetsi la DC ndi makina omwe amagwiritsa ntchito Direct current (DC) kuti apereke mphamvu pazida ndi zida zosiyanasiyana.Izi zingaphatikizepo machitidwe ogawa magetsi monga omwe amagwiritsidwa ntchito pa telecommunications, data centers ndi mafakitale.Makina amagetsi a DC nthawi zambiri amagwiritsidwa ntchito pomwe magetsi okhazikika komanso odalirika amafunikira, ndipo kugwiritsa ntchito magetsi a DC kumakhala kothandiza kwambiri kapena kothandiza kwambiri kuposa magetsi osinthika (AC).Makinawa nthawi zambiri amakhala ndi zinthu monga zokonzanso, mabatire, ma inverter, ndi zowongolera ma voltage kuti aziwongolera ndikuwongolera kayendedwe ka magetsi a DC.
Mfundo ya ntchito ya DC system
AC yogwira ntchito bwino:
Pamene kulowetsa kwa AC kumapereka mphamvu nthawi zonse, gawo logawa mphamvu la AC limapereka mphamvu ku gawo lililonse lokonzanso.Module yowongolera pafupipafupi imasintha mphamvu ya AC kukhala mphamvu ya DC, ndikuitulutsa kudzera pa chipangizo choteteza (fuse kapena chophwanyira dera).Kumbali imodzi, imayitanitsa paketi ya batri, ndipo kumbali ina, imapereka mphamvu yogwira ntchito yokhazikika ku katundu wa DC kudzera pagawo lamagetsi la DC.
Mphamvu ya AC ikugwira ntchito:
Makina olowetsa a AC akalephera ndipo mphamvu ikatha, gawo lokonzanso limasiya kugwira ntchito, ndipo batire imapereka mphamvu pakulemetsa kwa DC popanda kusokonezedwa.Module yowunikira imayang'anira kutulutsa kwamagetsi komanso komwe batire likuyenda munthawi yeniyeni, ndipo batire ikatuluka pamagetsi omaliza, gawo lowunikira limapereka alamu.Nthawi yomweyo, gawo lowunikira limawonetsa ndikuwongolera zomwe zidakwezedwa ndi dera lowunikira magetsi nthawi zonse.

Chidule cha Battery System
Dongosolo la batri limapangidwa ndi kabati ya batri ya LiFePO4 (lithium iron phosphate), yomwe imapereka chitetezo chokwanira, moyo wautali wautali, komanso kuchuluka kwamphamvu kwamphamvu potengera kulemera ndi voliyumu.
Dongosolo la batri lili ndi ma cell a batri a 144pcs LiFePO4:
selo lililonse 3.2V 230Ah.Mphamvu zonse ndi 105.98kwh.
Ma cell a 36pcs motsatizana, ma cell a 2pcs molingana = 115V460AH
115V 460Ah * 2sets mu kufanana = 115V 920Ah
Zosavuta kuyenda ndi kukonza:
seti imodzi ya mabatire a 115V460Ah imagawidwa muzotengera zazing'ono za 4 ndikulumikizidwa mndandanda.
Mabokosi 1 mpaka 4 amapangidwa ndi mndandanda wolumikizana ndi ma cell 9, okhala ndi ma cell a 2 omwe amalumikizidwanso mofanana.
Bokosi 5, kumbali ina, ndi Master Control Box mkati Kukonzekera kumeneku kumabweretsa ma cell 72.
Ma seti awiri a mapaketi a batri awa amalumikizidwa molumikizana,ndi seti iliyonse yolumikizidwa pawokha pamagetsi a DC,kuwalola kuti azigwira ntchito okha.

Chithunzi chamagetsi amagetsi ogwiritsira ntchito magetsi a DC
Dongosolo la DC lili ndi mabatire a 2 ndi seti 2 zokonzanso, ndipo cholumikizira mabasi cha DC chimalumikizidwa ndi magawo awiri a basi imodzi.
Nthawi yogwira ntchito bwino, masinthidwe amabasi amachotsedwa, ndipo zida zolipiritsa za gawo lililonse la basi zimayimitsa batire kudzera m'basi yothamangitsa, ndikupereka katundu wanthawi zonse nthawi yomweyo.
Mphamvu yoyandama kapena voteji yofananira ya batri ndi mphamvu yanthawi zonse yotuluka pa bar ya basi ya DC.
Mu dongosolo ili, pamene chipangizo cholipiritsa cha gawo lililonse la basi chikalephera kapena paketi ya batri iyenera kuyang'aniridwa kuti ipereke mayeso ndi kutulutsa, chosinthira cholumikizira mabasi chimatha kutsekedwa, ndipo chida cholipirira ndi paketi ya batri ya gawo lina la basi imatha kupereka mphamvu. ku dongosolo lonse, ndi bus tie circuit Ili ndi diode anti-return muyeso kuteteza ma seti awiri a mabatire kuti asalumikizidwe mofanana.

Kugwiritsa ntchito
Makina opangira magetsi a DC amagwiritsidwa ntchito kwambiri m'mafakitale ndi magawo osiyanasiyana.Zina zomwe zimagwiritsidwa ntchito pamagetsi a DC ndizo:
1. Matelefoni:Machitidwe amagetsi a DC amagwiritsidwa ntchito kwambiri pazida zoyankhulirana, monga nsanja za foni yam'manja, malo opangira ma data ndi maukonde olumikizirana, kuti apereke mphamvu zodalirika, zosagwirizana ndi zida zofunika kwambiri.
2. Mphamvu zongowonjezedwanso:Makina amagetsi a DC amagwiritsidwa ntchito pamagetsi ongowonjezwdwanso, monga kupanga magetsi a solar photovoltaic ndi kukhazikitsa magetsi opangira mphepo, kutembenuza ndi kuyang'anira magetsi a DC opangidwa ndi mphamvu zongowonjezwdwa.
3. Mayendedwe:Magalimoto amagetsi, masitima apamtunda, ndi mayendedwe ena nthawi zambiri amagwiritsa ntchito makina amagetsi a DC ngati njira zawo zoyendetsera ndi zothandizira.
4. Industrial Automation:Njira zambiri zamafakitale ndi makina opanga makina amadalira mphamvu ya DC kuwongolera makina, ma drive amagalimoto ndi zida zina.
5. Zamlengalenga ndi Chitetezo:Machitidwe amagetsi a DC amagwiritsidwa ntchito mu ndege, ndege ndi zida zankhondo kuti akwaniritse zosowa zosiyanasiyana zamagetsi, kuphatikizapo ma avionics, njira zoyankhulirana ndi zida zankhondo.
6. Kusungirako Mphamvu:Makina amagetsi a DC ndi gawo lofunikira la njira zosungiramo mphamvu zosungirako mphamvu monga makina osungira mabatire ndi magetsi osasunthika (UPS) opangira malonda ndi nyumba.
Izi ndi zitsanzo zochepa chabe za machitidwe osiyanasiyana amagetsi a DC, kuwonetsa kufunikira kwawo m'mafakitale angapo.
