Ukukhiqizwa kwamandla e-photovoltaic yelanga kuzodlala indima ebalulekile ekusetshenzisweni kwamandla emhlabeni esikhathini esizayo esiseduze, hhayi nje kuphela ukuze kuthathelwe indawo eminye imithombo yamandla evamile, kodwa futhi ukuze kube umthombo oyinhloko wokuhlinzekwa kwamandla emhlabeni.
Ama-inverter e-Photovoltaic angama-inverter aguqula i-voltage ye-DC eguquguqukayo ekhiqizwa amaphaneli elanga e-photovoltaic (PV) abe yi-utility frequency alternating current (AC), engabuyiselwa ohlelweni lokudlulisa oluthengiswayo noma esetshenziswe ohlelweni olungaphandle kwegridi. Njengoba ama-inverter ngokuvamile esetshenziswa esimweni sangaphandle futhi adinga ukusebenza okuthembekile kwesikhathi eside kanye nokugcinwa okuncane, abasebenzisi bokugcina kanye nabaklami banezidingo eziqinile kakhulu zekhwalithi kanye nokuthembeka kwezingxenye ezisetshenziswa kula madivayisi. Njengesithwali kanye nokusekelwa enkambisweni yokuguqulwa kwamandla, ama-capacitor efilimu adlala indima ebalulekile kuzo zonke izici zama-inverter e-photovoltaic. Uma engakhethwanga kahle, azoba nomthelela obulalayo ekuzinzeni nasekuphileni kwemishini.
Ukuze uyisebenzise kusekethe ye-inverter, sicela ubheke isibonelo sesicelo esithombeni esingezansi:
Indima ye-capacitor ye-DC-link:
1) Kusekhethi ye-inverter, i-voltage yokukhipha ye-rectifier ihlungwa futhi ihlungwe kakhulu;
2) Munca ugesi we-pulsating we-amplitude ephezulu ocelwe yi-inverter evela ku-"DC-Link", uyivimbele ekukhiqizeni i-voltage ye-pulsating ye-amplitude ephezulu ku-impedance ye-"DC-Link", bese ugcina ukuguquguquka kwe-voltage ebhasini le-DC ngaphakathi kobubanzi obuvumelekile;
3) Vimbela ukushaqeka ngokweqile kwe-voltage kanye nokushaqeka ngokweqile kwe-"DC-Link" ekuthinteni i-IGBT.
Ngakho-ke, izidingo zama-capacitor:
1) Qinisekisa ukuthi i-voltage iyamelana ngokwanele
2) Amandla anele
3) Amandla okusebenzisa amandla amaningi ngokweqile, i-ESR ephansi ngangokunokwenzeka
4) Udinga izici ezinhle zemvamisa, i-ESL ephansi ngangokunokwenzeka
5) Yanelisa izinga lokushisa eliphezulu langaphandle kanye nesimo sokusetshenziswa komswakama ophezulu
I-Wuxi CRE New Energy Technology Co., Ltd. ibilokhu igxile ekusetshenzisweni kwama-capacitor efilimu kuma-electronics anamandla isikhathi eside. Ihlose isimo esinzima sokusetshenziswa kuma-inverters e-photovoltaic, ngokusekelwe kubuchwepheshe befilimu obusekela i-DC obusekelwa yi-CRE, isebenzisa i-Polypropylene Dielectric elahlekelwa kancane, engamelani nokushisa okuphezulu iklame futhi yathuthukisa uchungechunge lwama-capacitor efilimu anokumelana nokushisa okuphezulu kanye nomswakama ophezulu, i-ESR ephansi (ukukhiqiza ukushisa okuphansi), ukuthembeka okuphezulu kanye nokuphila isikhathi eside.
Phakathi kwazo, izici zokusebenza ze-DMJ-PS DC bus capacitor yilezi ezilandelayo:
Izinga lokushisa eliphezulu lokusebenza: 105 °C (ibhokisi lepulasitiki)
Isigaba sesimo sezulu (IEC 60068-1:2013): 40/105/56
I-Dielectric: I-Polypropylene (MKP)
Ibhokisi lepulasitiki (UL 94 V-0)
Ukuvalwa kwe-resin (UL 94 V-0)
Inani lomthamo eliphezulu. 200μF
Ibanga le-voltage 300V~2000VDC
Ukusebenza okuhle kokuziphilisa, ukumelana nokushisa ngokweqile, ukumelana nokushisa okuphezulu kanye nokulahlekelwa okuphansi
Ukumelana nendawo eshisayo nenomswakama (85℃/85%RH 1000h), ukuthembeka okuphezulu, impilo yesevisi ende
Landela i-RoHS futhi uhlangabezane nezidingo ze-AEC-Q200 yebanga lezimoto
