Muri iki cyumweru tugiye gusesengura imikoreshereze yubushobozi bwa firime aho gukoresha amashanyarazi ya electrolytike muri capacitori ya DC.Iyi ngingo izagabanywamo ibice bibiri.

Hamwe niterambere ryinganda nshya zingufu, tekinoroji ihindagurika ikoreshwa mubisanzwe, kandi ubushobozi bwa DC-Ihuza nibyingenzi nkimwe mubikoresho byingenzi byo guhitamo.Ubushobozi bwa DC-Ihuza mumashanyarazi ya DC mubisanzwe bisaba ubushobozi bunini, gutunganya ibintu byinshi hamwe na voltage nyinshi, nibindi. Mugereranije ibiranga capacitori ya firime na capacitori ya electrolytike hamwe no gusesengura ibyerekeranye nayo, iyi mpapuro yanzura ko mubishushanyo mbonera bisaba ingufu zikora cyane, umuyaga mwinshi (Irms), ibisabwa hejuru ya voltage, voltage ihindagurika, inrush nini (dV / dt) nubuzima burebure.Hamwe nogutezimbere tekinoroji yo kubika ibyuka hamwe nubuhanga bwa firime ya capacitori, ubushobozi bwa firime bizahinduka inzira kubashushanya gusimbuza amashanyarazi ya electrolytique mubijyanye nibikorwa nigiciro kiri imbere.

Hashyizweho politiki nshya ijyanye n’ingufu no guteza imbere inganda nshya z’ingufu mu bihugu bitandukanye, iterambere ry’inganda zijyanye nabyo muri uru rwego ryazanye amahirwe mashya.Kandi ubushobozi, nkibyingenzi byingenzi bijyanye ninganda zicuruzwa, nazo zabonye amahirwe mashya yiterambere.Mu mbaraga nshya n’imodoka nshya zingufu, capacator nibintu byingenzi mugucunga ingufu, gucunga ingufu, inverter power na sisitemu yo guhindura DC-AC igena ubuzima bwihindura.Nyamara, muri inverter, imbaraga za DC zikoreshwa nkisoko yinjiza imbaraga, ihujwe na inverter binyuze muri bisi ya DC, yitwa DC-Ihuza cyangwa DC.Kubera ko inverter yakira RMS nini hamwe nimpanuka ya pulse iva kuri DC-Ihuza, itanga ingufu za pulse nini kuri DC-Ihuza, bigatuma bigora kwihanganira.Kubwibyo, ubushobozi bwa DC-Ihuza irakenewe kugirango ikuremo impiswi ndende kuva DC-Ihuza no gukumira ihindagurika ryinshi rya voltage ihindagurika rya inverter iri murwego rwemewe;kurundi ruhande, irinda kandi inverters kutagira ingaruka kumashanyarazi ya voltage hamwe na voltage irenze urugero kuri DC-Ihuza.

Igishushanyo mbonera cyo gukoresha ubushobozi bwa DC-Ihuza imbaraga mu mbaraga nshya (harimo kubyara ingufu z'umuyaga no kubyara amashanyarazi) hamwe na sisitemu nshya yo gutwara ibinyabiziga bitanga ingufu bigaragara mu gishushanyo cya 1 n'icya 2.

Igishushanyo cya 1 cyerekana umuyaga uhindura umuyaga umuyaga, aho C1 ari DC-Ihuza (muri rusange ihuriweho na module), C2 ni iyinjizwa rya IGBT, C3 ni LC iyungurura (uruhande rwa net), na C4 rotor kuruhande rwa DV / DT.Igishushanyo cya 2 cyerekana tekinoroji ya PV ihinduranya amashanyarazi, aho C1 ari DC iyungurura, C2 ni EMI iyungurura, C4 ni DC-Ihuza, C6 ni LC iyungurura (uruhande rwa grid), C3 ni DC iyungurura, naho C5 ni IPM / IGBT.Igishushanyo cya 3 cyerekana sisitemu nyamukuru yo gutwara ibinyabiziga muri sisitemu nshya y’ibinyabiziga bitanga ingufu, aho C3 ari DC-Ihuza na C4 ni capacitori ya IGBT.

Muri porogaramu nshya zavuzwe haruguru, ubushobozi bwa DC-Ihuza, nkigikoresho cyingenzi, birasabwa kugirango umuntu yizere cyane kandi arambe muri sisitemu y’amashanyarazi y’umuyaga, amashanyarazi y’amashanyarazi na sisitemu nshya y’imodoka, bityo guhitamo kwayo ni ngombwa cyane.Ibikurikira nugereranya ibiranga ubushobozi bwa firime na capacitori ya electrolytike hamwe nisesengura ryabo muri porogaramu ya DC-Ihuza.

1. Kugereranya neza

1.1 Ubushobozi bwa firime

Ihame rya tekinoroji ya metallisation yatangijwe bwa mbere: igipande cyoroshye cyane cyicyuma kivamo umwuka hejuru yibitangazamakuru byoroheje.Iyo hari inenge iri hagati, urwego rushobora guhinduka bityo rugatandukanya ahantu hafite inenge kugirango rukingirwe, ibintu bizwi nko kwikiza.

Igishushanyo cya 4 cyerekana ihame ryo gutwikisha ibyuma, aho itangazamakuru ryoroheje rya firime ryateguwe (corona yubundi) mbere yo guhumeka kugirango molekile yicyuma ibashe kuyubahiriza.Icyuma kivamo umwuka ushonga ubushyuhe bwinshi munsi ya vacuum (1400 ℃ kugeza 1600 ℃ kuri aluminium na 400 ℃ kugeza 600 ℃ kuri zinc), hamwe numwuka wibyuma byegeranye hejuru ya firime iyo ihuye na firime ikonje (ubushyuhe bwo gukonjesha firime) -25 ℃ kugeza -35 ℃), bityo bigakora icyuma.Iterambere ryikoranabuhanga rya metallisation ryateje imbere ingufu za dielectric ya firime dielectric ya firime yubugari bwa buri gice, kandi igishushanyo mbonera cya capacitori ya pulse cyangwa gusohora ikoreshwa ryikoranabuhanga ryumye rishobora kugera kuri 500V / µm, kandi igishushanyo mbonera cya capacitori ya DC ikoreshwa gishobora kugera kuri 250V / µm.Imiyoboro ya DC-Ihuza ni iyanyuma, kandi ukurikije IEC61071 kubijyanye nubushobozi bwa elegitoronike ikoresha amashanyarazi irashobora kwihanganira ihungabana rikomeye rya voltage, kandi irashobora kugera ku nshuro 2 za voltage zagenwe.

Kubwibyo, uyikoresha akeneye gutekereza gusa kuri voltage ikora ikenewe kubishushanyo byabo.Ububiko bwa firime metallized ifite ESR yo hasi, ibemerera kwihanganira imigezi minini;hepfo ya ESL yujuje ibyangombwa byo hasi ya inductance ibisabwa bya inverters kandi bigabanya ingaruka zinyeganyega muguhindura imirongo.

Ubwiza bwa firime dielectric, ubwiza bwikariso ya metallisation, igishushanyo mbonera hamwe nuburyo bwo gukora bigena imiterere yo kwikiza ibiranga ubushobozi bwa metallize.Filime dielectric ikoreshwa kuri capacitori ya DC-Ihuza yakozwe ni firime ya OPP.

Ibiri mu gice cya 1.2 bizashyirwa ahagaragara mu kiganiro gitaha.
