Solar photovoltaic power generation ichaita basa rinokosha mukushandiswa kwesimba renyika munguva pfupi iri kutevera, kwete chete kutsiva mamwe magetsi emagetsi, asiwo kuva iyo inonyanya kushandiswa kwesimba renyika.
Photovoltaic inverters inverters inoshandura iyo inoshanduka DC voltage inogadzirwa ne photovoltaic (PV) solar panels kuita utility frequency alternating current (AC), iyo inogona kudzoserwa mukutengesa transmission system kana kushandiswa mu off-grid system.Sezvo ma inverters achiwanzo shandiswa mumamiriro ekunze uye achida kushanda kwenguva refu uye kushomeka kwekugadzirisa, vashandisi vekupedzisira uye vagadziri vane yakanyanya kuomarara mhando uye kuvimbika zvinodiwa zvezvikamu zvinoshandiswa mumidziyo iyi.Semutakuri uye rutsigiro musimba rekushandura maitiro, mafirimu capacitors anoita basa rakakosha mune ese maficha e photovoltaic inverters.Kana vasina kusarudzwa zvakanaka, vachave nemigumisiro inouraya pakugadzikana uye hupenyu hwose hwemidziyo.
Kuti ushandise inverter wedunhu, ndapota tarisa kune iyo application muenzaniso mumufananidzo uri pazasi:
Basa reDC-link capacitor:
1) Muinverter circuit, iyo inobuda voltage yeinogadzirisa inonyanya kutsetseka uye kusefa;
2) Bvisa iyo yakakwira-amplitude pulsating ikozvino yakakumbirwa neinverter kubva ku "DC-Link", kudzivirira kuti irege kugadzira yakakwira-amplitude pulsating voltage pane iyo impedance ye "DC-Link", uye chengetedza kushanduka kwemagetsi paDC bhazi mukati inobvumirwa chiyero chiyero;
3) Dzivirira iyo voltage overshoot uye kupfuudza overvoltage ye "DC-Link" kubva pakukanganisa IGBT.
Naizvozvo, zvinodikanwa zve capacitors:
1) Ita shuwa kuti yakakwana inomira voltage
2) Capacitance yakakwana
3) Yakakwana pamusoro-ikozvino kugona, yakaderera ESR sezvinobvira
4) Inoda yakanaka frequency maitiro, yakaderera ESL sezvinobvira
5) Gutisa iyo yakaoma yekunze tembiricha yepamusoro uye yakakwirira humidity application mamiriro
Wuxi CRE New Energy Technology Co., Ltd yanga yakatarisana nekushandiswa kwemafirimu capacitor mumagetsi emagetsi kwenguva yakareba.Iine chinangwa chekuomesera mamiriro ekushandisa mu photovoltaic inverters, zvichibva paCRE's DC-inotsigirwa yakakwirira-inodzivirira firimu tekinoroji, inotora yakaderera-kurasikirwa, yakakwirira-yekushisa-inodzivirira Polypropylene Dielectric yakagadzira uye yakagadzira akatevedzana emufirimu capacitor ane tembiricha yepamusoro uye hunyoro hwepamusoro. kuramba, yakaderera ESR (yakaderera kupisa chizvarwa), yakakwirira kuvimbika uye hupenyu hurefu.
Pakati pavo, maitiro ekuita kweDMJ-PS DC bhazi capacitor ndeaya anotevera:
Kunyanya kupisa tembiricha: 105 °C (plastiki kesi)
Chikamu chemamiriro ekunze (IEC 60068-1:2013): 40/105/56
Dielectric: Polypropylene (MKP)
Bhokisi repurasitiki (UL 94 V-0)
Resin sealing (UL 94 V-0)
Capacitance value max.200μF
Voltage range 300V ~ 2000VDC
Yakanaka yekuzviporesa kuita, overvoltage resistance, high current resistance and low loss
Kupokana nenzvimbo inopisa uye ine hunyoro (85 ℃/85% RH 1000h), kuvimbika kwepamusoro, hupenyu hurefu hwebasa.
Teerera neRoHS uye usangane nezvinodiwa zvegiredhi remota AEC-Q200
