Makampani osungira mphamvu ndi gawo lofunika kwambiri pa dongosolo lamakono la mphamvu. Inverter imagwira ntchito zambiri mu dongosolo lamakono losungira mphamvu, kuphatikizapo kusintha mphamvu, kuwongolera ndi kulumikizana, kuteteza kudzipatula, kuwongolera mphamvu, kuyatsa ndi kutulutsa mphamvu mbali zonse ziwiri, kuwongolera mwanzeru, chitetezo chambiri komanso kugwirizana kwamphamvu, zomwe zimapangitsa inverter kukhala imodzi mwa zigawo zofunika kwambiri pa dongosolo losungira mphamvu.
Ma inverter osungira mphamvu nthawi zambiri amakhala ndi makina olowetsa, otulutsa, ndi owongolera. Ma capacitor amagwira ntchito mu inverter, kuphatikizapo kukhazikika kwa magetsi ndi kusefa, kusunga ndi kumasula mphamvu, kukonza mphamvu, kuteteza ndi kusalala kwa DC pulsation. Izi zimagwira ntchito limodzi kuonetsetsa kuti inverter ikugwira ntchito bwino komanso ikugwira ntchito bwino kwambiri. Pa makina osungira mphamvu, imatha kukonza magwiridwe antchito onse komanso kukhazikika kwa makinawo.
Ubwino wa ma capacitor a YMIN mu ma inverters
Kuchuluka kwa mphamvu:
Chosinthira magetsi chimalandira magetsi opangidwa ndi zipangizo zamagetsi zongowonjezedwanso monga ma solar panels kapena ma wind turbines ndikuchisintha kukhala magetsi omwe amakwaniritsa zosowa. Munjira iyi, popeza mphamvu yamagetsi imatha kuwonjezeka nthawi yomweyo, chosinthira magetsi chiyenera kukhala ndi mphamvu zolamulira mphamvu kuti chitsimikizire kuti magetsi akuyenda bwino.
Ma capacitor a electrolytic a aluminiyamu a YMINali ndi ubwino wokhala ndi mphamvu zambiri, zomwe zimatha kusunga chaji yambiri mu voliyumu yomweyo, kukwaniritsa mokwanira kufunikira kwa mphamvu yamagetsi yomwe ingakwere nthawi yomweyo. Pakugwira ntchito kwa inverter, izi zimatsimikizira kutulutsa bwino kwa mphamvu yamagetsi.
Kukana kwamphamvu kwa ripple current:
Pa nthawi yogwira ntchito ya inverter, ngati kukonza mphamvu sikukuchitika, mphamvu yamagetsi yomwe imachokera imatha kukhala ndi zinthu zambiri zolumikizana. Ma capacitor a YMIN aluminiyamu, omwe ali ndi kukana kofanana ndi kotsika (ESR) komanso mawonekedwe abwino kwambiri a ma frequency, amatha kuchepetsa bwino kuchuluka kwa ma harmonic, osati kungokwaniritsa kufunikira kwa mphamvu ya AC yapamwamba, komanso kuonetsetsa kuti inverter ikutsatira miyezo yoyenera yolumikizira gridi, kuchepetsa kusokoneza ndi kusokoneza gridi.
Kuphatikiza apo, kumbali ya DC input ya inverter, ma YMIN capacitors, omwe ali ndi capacitance density yayikulu komanso magwiridwe antchito abwino kwambiri osefa, amatha kusefa phokoso ndi kusokoneza mu input DC power supply, kuonetsetsa kuti input current ndi yoyera kwambiri, potero amachepetsa mphamvu ya ma interference signals pazigawo zotsatira za inverter circuit ndikukweza mokwanira kukhazikika ndi magwiridwe antchito a system.
Ubwino wokana mphamvu yamagetsi:
Chifukwa cha kusintha kwa mphamvu ya kuwala, mphamvu yamagetsi yotulutsa ya makina a photovoltaic ikhoza kukhala yosakhazikika, ndipo zida zamagetsi zamagetsi zomwe zili mu inverter zimapanganso mphamvu yamagetsi ndi mphamvu yamagetsi panthawi yosinthira. Mikwingwirima iyi ingayambitse kuwonongeka kwa zida zamagetsi. Chifukwa chake, capacitor ya buffer imagwira ntchito yofunika kwambiri poyamwa mphamvu yamagetsi ndi mphamvu yamagetsi ndikuteteza zida zamagetsi ku mphamvu yamagetsi yochulukirapo kapena mphamvu yamagetsi. Nthawi yomweyo, capacitor imatha kusuntha kusintha kwa mphamvu yamagetsi ndi mphamvu yamagetsi, kuchepetsa kutayika kwa mphamvu panthawi yosinthira, motero kukonza magwiridwe antchito komanso kukhazikika kwa inverter.
YMINMalangizo osankha capacitor mu inverter:
Chidule:
Ma capacitor a YMINZasintha kwambiri magwiridwe antchito a ma inverter mu makina osungira mphamvu ndi makhalidwe awo abwino monga kukana kwa magetsi ambiri, kuchuluka kwa mphamvu zambiri, ESR yotsika, komanso kukana kwamphamvu kwa ripple current. Sikuti zimangochepetsa kutayika mu njira yosinthira mphamvu kudzera mu machitidwe abwino kwambiri osefera ndi malamulo a voltage, komanso zimatha kusintha mokhazikika magetsi, magetsi ndi ma frequency kuti zitsimikizire kuti makina amatulutsa mphamvu modalirika. Nthawi yomweyo, ma capacitor amatha kuyamwa mwachangu kugwedezeka kwakanthawi komanso kugunda kwa magetsi kosalala, zomwe zimapangitsa kuti makinawo asasokonezeke komanso kukhazikika. Kuphatikiza apo, ma capacitor a YMIN amathandizira bwino kusunga ndi kutulutsa mphamvu panthawi yochapira ndi kutulutsa mphamvu, kukulitsa kugwiritsa ntchito mphamvu bwino kwa makina osungira mphamvu ndikuthandiza makina onse kuti akwaniritse bwino kusintha mphamvu, kukhazikika kwambiri, komanso kuchepa kwa mphamvu.
