一, Photovoltaic systems boom
Ndikugogomezera kwambiri chitetezo cha chilengedwe padziko lonse lapansi, makina a photovoltaic akhala akugwiritsidwa ntchito kwambiri m'madera osiyanasiyana. Mumsika wamagetsi, machitidwe a photovoltaic sangathe kupereka magetsi ku mizinda, komanso amapereka magetsi ndi mauthenga oyankhulana kumadera akutali. Panthawi imodzimodziyo, makina a photovoltaic ali ndi ndalama zotsika mtengo komanso zotsika mtengo zogwirira ntchito, choncho amakondedwa ndi mabungwe ambiri ndi mabungwe a boma.
二、 Ma inverters a Photovoltaic ali ndi mavuto oti athetse
Photovoltaic inverter ndi chipangizo chomwe chimasintha magetsi omwe amapangidwa ndi mapanelo a photovoltaic kukhala alternating current. Imayang'anira ma voliyumu ndi zomwe zikuchitika pano ndi mapanelo a photovoltaic kudzera pamlingo wapamwamba kwambiri wotsata ma algorithm, imazindikira kukwera ndi kutsika kwamagetsi, ndikuisintha kukhala magetsi okhazikika apakali pano. Kenako, inverter imatembenuza mphamvu ya DC kukhala mphamvu ya AC pogwiritsa ntchito ukadaulo wapamwamba kwambiri wa pulse wide modulation, ndikuwongolera kudzera pa fyuluta yotulutsa kuti zitsimikizire mtundu ndi kukhazikika kwa zomwe zimatulutsa pano. Pamapeto pake, inverter imalumikiza mphamvu ya AC ku gridi yamagetsi kuti ikwaniritse zosowa zamagetsi apanyumba kapena mafakitale. Mwanjira iyi, ma inverters a photovoltaic amagwira ntchito yofunika kwambiri pakusintha mphamvu ya dzuwa kukhala magetsi ogwiritsidwa ntchito.
Pakali pano, 1000 ~ 2200W photovoltaic inverter yomwe imagwiritsidwa ntchito pamapeto opangira mphamvu ya photovoltaic ili ndi nsonga yotulutsa magetsi mpaka 580V. Komabe, 500V yotulutsa capacitor yomwe ilipo sikungathenso kukwaniritsa zosowa za photovoltaic inverters. Pakati pawo, ma aluminium electrolytic capacitors amatenga gawo lofunikira, lomwe silingangopereka zofunikira zosefera ndi kusungirako, komanso kuwonetsetsa kudalirika komanso kuthekera kwadongosolo lonse. Ngati mphamvu yotulutsa sikwanira, imapangitsa kuti capacitor itenthe, kusweka, ndikuwonongeka. Choncho, m'pofunika kuganizira mozama zinthu zosiyanasiyana posankha electrolytic capacitor, ndi kusankha mankhwala oyenera kwambiri kuonetsetsa ntchito bwino dongosolo ndi kupeza ntchito bwino.
三、Yongming high-voltage lead-type capacitors amathetsa "high voltage" mwadzidzidzi
Pofuna kuthana ndi vuto lamphamvu lamagetsi la ma inverters a photovoltaic, Shanghai Yongming idakhazikitsa ma LKZ otsogola apamwamba kwambiri amtundu wa LKZ aluminiyamu electrolytic capacitors. Banjali lili ndi magwiridwe antchito ake ndipo limagwira ntchito mosiyanasiyana mosiyanasiyana, kuphatikiza ma voltages apamwamba kwambiri mpaka 580V. Kuchita bwino kwambiri kwa ma capacitors a LKZ kumatha kupititsa patsogolo kukhazikika komanso mphamvu ya ma inverters a photovoltaic ndikupatsa makasitomala mayankho abwino kwambiri.
1, Super amphamvu maopaleshoni ndi kukana zotsatira: LKZ mndandanda zotayidwa electrolytic capacitors akhoza kufika 600V voteji, amene mosavuta kusamalira nsonga voteji ndi lalikulu panopa pa linanena bungwe.
2, Ultra-otsika kukana mkati ndi makhalidwe abwino otsika kutentha: Poyerekeza ndi capacitors Japanese za mfundo zomwezo, impedance wa Yongming capacitors yafupika pafupifupi 15% ~ 20%, amene amaonetsetsa yaing'ono kutentha kukwera, lalikulu ripple kukana ndi - 40 ℃ magwiridwe antchito a capacitor panthawi yogwira ntchito. Makhalidwe otsika kutentha, kotero kuti capacitor sichidzalephereka kumayambiriro kwa ntchito yayitali.
3, Apamwamba mphamvu kachulukidwe: Yongming zotayidwa electrolytic capacitors ndi oposa 20% zazikulu kuposa capacitors Japanese wa mfundo zofanana ndi kukula, ndi apamwamba kachulukidwe mphamvu ndi zotsatira bwino kusefa; pa nthawi yomweyo, pansi zofunika mphamvu yomweyo, ntchito Yongming Larger mphamvu electrolytic capacitors akhoza kuchepetsa mtengo makasitomala mwa mawu capacitance.
4, Kudalirika kwakukulu: Ma capacitor a electrolytic a Yongming amapereka chitsimikizo chokwanira cha kukhazikika ndi kudalirika kwa zigawo zikuluzikulu zamagetsi monga photovoltaic inverters, zomwe zimapangitsa kuti ntchito yonse ya photovoltaic ikhale yabwino kwambiri.
Mphamvu yamagetsi: 550 ~ 600V
Mtundu wa mphamvu: 82 ~ 220μF
Ntchito kutentha: -40 ~ 105 ℃
Kutalika kwa moyo: 12000 ~ 15000H
四、Pangani ma capacitor apamwamba kwambiri apakhomo ndikupita kumsika wapadziko lonse lapansi
Monga capacitor yatsopano yapakhomo, Yongming's liquid lead aluminium electrolytic capacitor ali ndi ubwino waukulu pakugwiritsa ntchito ma inverters a photovoltaic, kupereka chitsimikizo champhamvu cha kukhazikika kwa dongosolo la photovoltaic, ndi ntchito yake yonse ikufanana ndi ya ma capacitor aku Japan. .
