Thin film capacitor ndi gawo lomwe limawunikiridwa kwambiri pamabwalo apakompyuta ndipo ali ndi zabwino zomwe zimakhala zokhazikika komanso moyo wautali. Malinga ndi mitundu yosiyanasiyana yogwiritsira ntchito, ma capacitor amakanema amatha kugawidwa m'magulu monga mabwalo a DC ndi ma AC. M'mabwalo a DC, ma capacitor ake amakanema amagwiritsidwa ntchito makamaka ngati kupondereza, kusalaza, ndi kusunga mphamvu, pomwe m'mabwalo a AC, amakhala ndi udindo woyimitsa kusokoneza kwanthawi yayitali, kukonza mphamvu zamagetsi, komanso kuyambitsa ma mota. Makamaka pamakina oyendetsa magalimoto, ma capacitor amakanema amakhala ndi mawonekedwe okwera kwambiri komanso kukana kwamagetsi, zomwe zimawapangitsa kukhala zida zowongolera poyambira ndikugwira ntchito. Nkhaniyi ifotokoza za ntchito ndi ubwino wa metallized filimu capacitors mu galimoto kuyambira.
01 Kugwiritsa ntchito ma capacitor azitsulo zamakanema pamagalimoto oyendetsa ndikuthana ndi mavuto
M'makina oyendetsa magalimoto, ma capacitor amakanema amagwiritsidwa ntchito mbali ya DC ndi mbali ya AC motsatana, kuthetsa mavuto ambiri.
| Ntchito ya DC side film capacitor: | |
| Ntchito | Zotsatira ndi ubwino |
| Kusinthasintha kwamphamvu kwamagetsi | Pewani kuwonongeka kwamagalimoto chifukwa cha kusakhazikika kwamagetsi |
| Kukhazikika kwamagetsi | Onetsetsani kuti makina oyendetsa galimoto amagwira ntchito bwino pamalo okhazikika amagetsi |
| AC mbali filimu capacitor ntchito: | |
| Ntchito | Zotsatira ndi ubwino |
| Kusefa ndi kubwezera mphamvu | Limbikitsani mphamvu zoyambira zamagalimoto, chepetsani kuthamangitsidwa kwakanthawi poyambira, ndikuchepetsa zolemetsa zoyambira |
| Chepetsani phokoso ndi kugwedezeka | Kupititsa patsogolo kukhazikika kwagalimoto ndikuwonetsetsa kuti injini ikuyenda bwino |
| Sinthani mphamvu yamagetsi | Chepetsani kutaya mphamvu ndikuwongolera magwiridwe antchito |
02 Kuyerekeza kwa ma capacitor a filimu opangidwa ndi zitsulo ndi ma aluminium electrolytic capacitors
Ma capacitor amakanema opangidwa ndi zitsulo ali ndi maubwino odziwikiratu kuposa ma aluminium electrolytic capacitor potengera kupirira kwamagetsi. Ma capacitor amakanema opangidwa ndi zitsulo nthawi zambiri amakhala ndi mphamvu yopirira kwambiri ndipo amatha kugwira ntchito mokhazikika m'malo ovuta kwambiri. Mosiyana ndi izi, ma aluminiyamu electrolytic capacitor ali ndi mphamvu zochepa zopirira, zomwe zimalepheretsa kugwiritsidwa ntchito kwawo pamagetsi ena apamwamba kwambiri. Chifukwa chake, ma capacitor amakanema opangidwa ndi zitsulo ndi oyenera kwambiri pamakina oyendetsa magalimoto okhala ndi magetsi okwera komanso zofunika kukhazikika.
03 YMIN zitsulo zosankhidwa za filimu capacitor
Mndandanda wa MAP ndi mndandanda wa MDP wopangidwa ndi zitsulo zamakanema oyambitsidwa ndiYMINZamagetsi zidapangidwa mwapadera kuti zizitha kuyendetsa bwino ma mota kuti zikwaniritse zosowa zamitundu yosiyanasiyana yogwirira ntchito.

Pamene ukadaulo wamagalimoto ukupita patsogolo pakuchita bwino kwambiri, kupulumutsa mphamvu ndi luntha, kukonza zoyambira bwino komanso kudalirika kwantchito kwakhala cholinga chachikulu. Ma capacitor amakanema opangidwa ndi zitsulo amatenga gawo lofunikira pamakina oyendetsa magalimoto chifukwa chakuchita bwino kwambiri.YMINMndandanda wa MAP ndi ma capacitor a mafilimu a MDP, okhala ndi mphamvu zolimba kwambiri, ESR yochepa komanso moyo wautali, amapereka mayankho ogwira mtima a zida zamagalimoto m'mafakitale ndi ogula. M'tsogolomu, ndi chitukuko chofulumira cha ukadaulo watsopano wamagetsi ndi kupanga mwanzeru, ma capacitor opangidwa ndi zitsulo azitha kuwongolera magwiridwe antchito awo kuti akwaniritse kachulukidwe kakakulu kapano, moyo wautali komanso kugwiritsa ntchito mphamvu zochepa, kuthandizira makina oyendetsa magalimoto kupita kumagulu apamwamba. mlingo.
