Imirasire y'izuba niyihe kandi niyihe mikorere ya inverter

Niki aizuba

Sisitemu y'amashanyarazi akomoka ku mirasire y'izuba igizwe naimirasire y'izuba, kugenzura amafaranga, inverter nabateri ; sisitemu yo kubyara ingufu za DC ntabwo ikubiyemo inverter. Inverter nigikoresho cyo guhindura imbaraga. Inverters irashobora kugabanwa muburyo bwo kwishima kwinyeganyeza inverter hamwe na inverter yishimye itandukanye ukurikije uburyo bwo kwishima. Igikorwa nyamukuru nuguhindura imbaraga za DC za bateri mumashanyarazi ya AC. Binyuze mumuzunguruko wuzuye, ikirangantego cya SPWM gikoreshwa muburyo bwo guhinduranya, kuyungurura, kongera ingufu za voltage, nibindi kugirango ubone ingufu za sinusoidal AC zihuye numuriro wumuriro, voltage yagenwe, nibindi kubakoresha sisitemu ya nyuma. Hamwe na inverter, bateri ya DC irashobora gukoreshwa mugutanga ingufu za AC kubikoresho.

2. Ubwoko bwa inverter

 

(1) Gutondekanya ukurikije urwego rusaba:

 

(1) Inverter isanzwe

 

DC 12V cyangwa 24V yinjiza, AC 220V, 50Hz isohoka, ingufu kuva 75W kugeza 5000W, moderi zimwe zifite AC na DC ihinduka, ni ukuvuga imikorere ya UPS.

 

(2) Inverter / charger yose-muri-imwe imashini

 

Muri ibiubwoko bwa inverter, abakoresha barashobora gukoresha uburyo butandukanye bwingufu kugirango bakoreshe AC imizigo: mugihe hari ingufu za AC, ingufu za AC zikoreshwa mugukoresha imizigo binyuze muri inverter, cyangwa kwishyuza bateri; iyo nta mbaraga za AC, bateri ikoreshwa mugukoresha AC umutwaro. . Irashobora gukoreshwa ifatanije nimbaraga zitandukanye: bateri, generator, imirasire yizuba hamwe na turbine yumuyaga.

 

(3) Inverter idasanzwe ya posita n'itumanaho

 

Tanga ubuziranenge bwa 48V inverters kumaposita n'itumanaho, itumanaho. Ibicuruzwa byayo bifite ubuziranenge, bwizewe cyane, modular (module ni 1KW) inverter, kandi ifite imikorere ya N + 1 kandi irashobora kwagurwa (imbaraga kuva 2KW kugeza 20KW).

 

4) Inverter idasanzwe yindege nigisirikare

Ubu bwoko bwa inverter bufite 28Vdc yinjiza kandi irashobora gutanga ibisubizo bya AC bikurikira: 26Vac, 115Vac, 230Vac. Ibisohoka inshuro zishobora kuba: 50Hz, 60Hz na 400Hz, naho ingufu zisohoka kuva 30VA kugeza 3500VA. Hariho kandi DC-DC ihindura hamwe na frequency ihindura indege.

(2) Gutondekanya kubisohoka byasohotse:

 

(1) Inverter ya kare

 

AC voltage yumurongo usohoka ukoresheje kwaduka kwaduka inverter ni kare. Inzira ya inverter ikoreshwa nubu bwoko bwa inverter ntabwo ihwanye neza, ariko ibisanzwe ni uko umuzenguruko woroshye ugereranije numubare wamashanyarazi akoreshwa ni muto. Imbaraga zo gushushanya muri rusange ziri hagati ya watt ijana na kilowatt imwe. Ibyiza bya kare kwaduka inverter ni: umuzunguruko woroshye, igiciro gihenze no kubungabunga byoroshye. Ikibi ni uko voltage yumurongo wa kwadiri irimo umubare munini wubwuzuzanye bwo murwego rwohejuru, bizatanga igihombo cyinshi mubikoresho bitwara imizigo hamwe na inductor cyangwa ibyuma bihindura ibyuma, bitera kwivanga kumaradiyo nibikoresho bimwe na bimwe byitumanaho. Mubyongeyeho, ubu bwoko bwa inverter bufite ibitagenda neza nkurwego rudahagije rwo kugenzura ingufu za voltage, imikorere yo kurinda ituzuye, hamwe n urusaku rwinshi.

 

2) Intambwe yimbere

AC voltage yumurongo usohoka kubwubu bwoko bwa inverter nintambwe. Hariho imirongo myinshi itandukanye kugirango inverter imenye intambwe yasohotse, kandi umubare wintambwe mubisohoka byahindutse bitandukanye cyane. Ibyiza byintambwe ya inverter ni uko ibisohoka byahinduwe neza cyane ugereranije na kwaduka kwaduka, kandi ibintu biri murwego rwo hejuru bihuza bigabanuka. Iyo intambwe igeze kuri 17, ibisohoka bisohoka birashobora kugera kumurongo wa sinasi. Iyo ukoresheje ibisohoka bidahinduka, imikorere rusange iri hejuru cyane. Ikibi ni uko urwego rwumuzunguruko urwego rwumuzunguruko rukoresha imiyoboro myinshi yo guhinduranya amashanyarazi, kandi bimwe muburyo bwumuzunguruko bisaba ibyiciro byinshi byinjiza ingufu za DC. Ibi bizana ibibazo mumatsinda hamwe no kwifashisha imirasire y'izuba hamwe no kwishyiriraho ingufu za bateri. Mubyongeyeho, voltage yumurongo wintambwe iracyafite interineti yihuta cyane kumaradiyo nibikoresho bimwe byitumanaho.

 

(3) Inverter ya Sine

 

AC voltage waveform isohoka na sine wave inverter ni sine wave. Ibyiza bya sine wave inverter nuko ifite umusaruro mwiza wo gusohora, kugoreka gake, kutivanga gake kumaradiyo nibikoresho byitumanaho, n urusaku ruke. Mubyongeyeho, ifite ibikorwa byo kurinda byuzuye hamwe nubushobozi buhanitse. Ibibi ni: umuzenguruko uragoye, bisaba tekinoroji yo kubungabunga cyane, kandi bihenze.

 

Itondekanya ryubwoko butatu bwa inverters bufasha kubashushanya nabakoresha sisitemu ya fotokoltaque na sisitemu yumuyaga kugirango bamenye kandi bahitemo inverter. Mubyukuri, inverter zifite imiterere imwe iracyatandukanye cyane mubijyanye namahame yumuzunguruko, ibikoresho byakoreshejwe, uburyo bwo kugenzura, nibindi.

 

3. Ibikorwa nyamukuru byimikorere ya inverter

 

Hano hari ibipimo byinshi nuburyo bwa tekiniki busobanura imikorere ya inverter. Hano turatanga gusa ibisobanuro muri make ibipimo bya tekiniki bikunze gukoreshwa mugihe dusuzuma inverter.

1. Ibidukikije kugirango ukoreshe inverter

7. Ubushobozi burenze urugero

 

Mubihe byagenwe, ubushobozi bwa inverter busohoka burenze agaciro kagereranijwe mugihe gito. Ubushobozi burenze urugero bwa inverter bugomba kuba bwujuje ibisabwa munsi yumutwaro wagenwe.

 

8. Imikorere inverter

 

Munsi yikigereranyo cyasohotse voltage, ibisohoka, ibyagezweho nibisobanuro byerekana imbaraga zingirakamaro, ikigereranyo cya inverter isohoka imbaraga zinjiza imbaraga zinjiza (cyangwa imbaraga za DC).

 

9. Umutwaro w'ingufu

 

Impinduka zemewe zo guhinduranya ibintu bya inverter yimitwaro isabwa kuba 0.7-1.0.

 

10. Fata asimmetrie

 

Munsi ya 10% umutwaro udasanzwe, asimmetrie yumurongo uteganijwe wibyiciro bitatu inverter isohoka voltage igomba kuba ≤10%.

 

11. Ibisohoka voltage asimmetrie

 

Mubikorwa bisanzwe bisanzwe, umutwaro wa buri cyiciro urasa, kandi asimmetrie yumusaruro wa voltage ugomba kuba ≤5%.

 

12． Gutangira ibiranga

Mubikorwa bisanzwe bisanzwe, inverter igomba kuba ishobora gutangira mubisanzwe inshuro 5 zikurikiranye munsi yumutwaro wuzuye kandi nta mikorere yimikorere.

 

13. Igikorwa cyo kurinda

 

Inverter igomba kuba ifite ibikoresho: kurinda imiyoboro ngufi, kurinda birenze urugero, kurinda amashanyarazi arenze, kurinda munsi ya voltage no kurinda icyiciro.

 

15. Kwivanga no kurwanya kwivanga

 

Inverter igomba kuba ishobora guhangana na electromagnetic yivanga mubidukikije muri rusange mugihe cyakazi gisanzwe. Imikorere irwanya kwivanga hamwe na electromagnetic ihuza inverter igomba kubahiriza ibipimo bifatika.

 

16. urusaku

 

Inverters idakunze gukoreshwa, gukurikiranwa no kubungabungwa igomba kuba ≤95db;

 

Inverters ikoreshwa kenshi, ikurikiranwa kandi ikomeza igomba kuba ≤80db.

 

17. kwerekana

 

Inverter igomba kuba ifite amakuru yerekanwe kubipimo nka AC isohoka ya voltage, ibisohoka, hamwe nibisohoka inshuro nyinshi, kimwe nibimenyetso byerekana ibyinjijwe bizima, imbaraga, hamwe nikibazo.

 

4. Menya imiterere ya tekiniki ya inverter:

 

Iyo uhisemo inverter ya sisitemu yuzuzanya ya fotovoltaque / umuyaga wumuyaga, ikintu cya mbere ugomba gukora nukumenya ibipimo byingenzi bya tekiniki byingenzi bikurikira bya inverter: kwinjiza amashanyarazi ya DC, nka DC24V, 48V, 110V, 220V, nibindi.;

 

Ikigereranyo gisohoka voltage, nkibice bitatu 380V cyangwa icyiciro kimwe 220V;

 

Ibisohoka bya voltage isohoka, nka sine wave, trapezoidal wave cyangwa kwaduka kare.
