Kugadzirwa kwesimba remagetsi rinoshandisa simba rezuva kuchaita basa guru mukushandiswa kwesimba repasi rose munguva pfupi iri kutevera, kwete kungotsiva mamwe masosi esimba akajairika, asiwo kuva sosi huru yesimba repasi rose.
Ma inverter e photovoltaic i ma inverter anoshandura voltage ye DC inoshanduka inogadzirwa nema solar panels e photovoltaic (PV) kuita utility frequency alternating current (AC), iyo inogona kudzoserwa mu commercial transmission system kana kushandiswa mu off-grid system. Sezvo ma inverter achiwanzo shandiswa panze uye achida kushanda kwenguva refu uye kugadziriswa kushoma, vashandisi vekupedzisira nevagadziri vane zvinodiwa zvakanyanya zvemhando yepamusoro uye kuvimbika kwezvikamu zvinoshandiswa mumidziyo iyi. Semutakuri uye rutsigiro mukuchinja simba, ma capacitor efirimu anoita basa rakakosha mune zvese zvikamu zve photovoltaic inverters. Kana akasasarudzwa nemazvo, achava nemhedzisiro inouraya pakugadzikana uye hupenyu hwemidziyo.
Kuti ushandise mudunhu re inverter, ndapota tarisa muenzaniso wekushandisa uri pamufananidzo uri pazasi:
Basa reDC-link capacitor:
1) Mudunhu re inverter, voltage inobuda ye rectifier inonyanya kutsvedzererwa uye kusefa;
2) Kunwisa simba remagetsi rinoita kuti magetsi apinde mu "DC-Link" rinokumbirwa ne "DC-Link", kudzivirira kuti rirege kugadzira simba remagetsi rinopinda mu "DC-Link" rinopinda mu "DC-Link", uye kuchengetedza kushanduka kwesimba remagetsi pabhasi reDC mukati mechiyero chinobvumidzwa;
3) Kudzivirira kukwira kwemagetsi zvakanyanya uye kukwira kwemagetsi kwenguva pfupi kwe "DC-Link" kuti kusakanganisa IGBT.
Saka, zvinodiwa zve capacitors:
1) Iva nechokwadi chekuti voltage yakakwana inomira
2) Kukwanisa kwakakwana
3) Kukwanisa kushanda nesimba zvakanyanya, ESR yakaderera sezvinobvira
4) Unoda hunhu hwakanaka hwema frequency, ESL yakaderera sezvinobvira
5) Gutsikanai nekupisa kwakanyanya kwekunze uye hunyoro hwakanyanya hwekushandisa
Kambani yeWuxi CRE New Energy Technology Co., Ltd. yagara ichitarisa pakushandiswa kwema capacitor efirimu mumagetsi emagetsi kwenguva yakareba. Ichitarisa mamiriro akaoma ekushandiswa muma inverters e photovoltaic, zvichibva pa tekinoroji yemafirimu inotsigirwa neCRE's DC, inoshandisa Polypropylene Dielectric isingarasikirwe zvakanyanya, inodzivirira kupisa kwakanyanya, yakagadzira nekugadzira nhevedzano yema capacitor efirimu ane tembiricha yakakwira uye hunyoro hwakanyanya, ESR yakaderera (kudzikisa kupisa), kuvimbika kwakanyanya uye hupenyu hurefu.
Pakati pavo, hunhu hwekushanda kweDMJ-PS DC bus capacitor ndeinotevera:
Tembiricha yepamusoro yekushandisa: 105 °C (bhokisi repurasitiki)
Chikamu chemamiriro ekunze (IEC 60068-1:2013): 40/105/56
Dielectric: Polypropylene (MKP)
Bhokisi repurasitiki (UL 94 V-0)
Kuvhara resin (UL 94 V-0)
Kukosha kwesimba remagetsi kwakakwirira. 200μF
Voltage range 300V~2000VDC
Kushanda zvakanaka kwekuzvirapa, kuramba kupisa kwakanyanya, kuramba kupisa kwakanyanya uye kurasikirwa kwakaderera
Kuramba kunzvimbo inopisa uye ine hunyoro (85℃/85%RH 1000h), kuvimbika kwakanyanya, hupenyu hurefu hwebasa
Tevedzera RoHS uye sangana nezvinodiwa zveAEC-Q200 yegiredhi remotokari
