Ni mu buhe buryo amashanyarazi ya UPS akoreshwa cyane?
Ibikoresho bya UPS bitanga ibikoresho nubwoko bwa mbere bwibikoresho byamakuru, bikoreshwa cyane cyane mukurinda umutekano wa sisitemu yamakuru ya mudasobwa, sisitemu yitumanaho, imiyoboro ya data igendanwa, nibindi. urunigi, inganda zo mu kirere, n'ibindi. ubwiza bwa gride ya gride, no gukumira imbaraga zamashanyarazi ako kanya hamwe no kunanirwa kwamashanyarazi bitunguranye byangiza abakoresha.uruhare.
Ubwoko bwa kabiri bwingufu zinganda ibikoresho bya sisitemu yo gutanga amashanyarazi UPS ikoreshwa cyane cyane mubijyanye ningufu zamashanyarazi, ibyuma, ibyuma bidafite fer, amakara, peteroli, ubwubatsi, ubuvuzi, imodoka, ibiryo, igisirikare nizindi nzego mubikorwa byinganda zikoresha ingufu zinganda .Inganda zo mu rwego rwo hejuru zidashobora gutanga amashanyarazi ni ibicuruzwa byo mu rwego rwo hejuru mu gutanga amashanyarazi adahagarara.Harimo tekinoroji ya elegitoroniki yububasha bwo guhindura ingufu nyinshi (wenda megawatt-urwego) guhindura ingufu, sisitemu yo kugenzura ibyuma bya digitale, tekinoroji ya AC ikurikirana, tekinoroji ya pulse ikora yo guhagarika, ikoranabuhanga ribyara ingufu nyinshi, nibindi. Biragaragara ko ibigo bisanzwe bitanga amashanyarazi bidashobora kwinjira inganda.Gusa ibigo bifite tekinoroji ya elegitoroniki ifite ingufu nyinshi hamwe nuruhererekane rwo guteza imbere ibicuruzwa, gukora nubushobozi bwa serivisi, hamwe nuburambe bujyanye ninganda n’inganda zikoreshwa, birashobora gukora akazi keza mugushushanya uburyo bwo gutanga amashanyarazi adahagarara, Gukora no kugurisha isoko serivisi.
Kugeza ubu, hari gahunda enye zo nini-nini ya UPS yinjiza ihuza ryubu
gahunda 1.
6-pulse UPS + ikora cyane-itondekanya neza-ihuza ibiyungurura, iyinjiza iri murwego rwohejuru-ihuza <5% (umutwaro wagenwe), ibintu byinjiza 0.95.Iyi gahunda ituma ibyinjira byinjira ari byiza cyane, ariko ikoranabuhanga ryayo ntirirakura, kandi hariho ibibazo nkindishyi zamakosa, indishyi zirenze urugero, nibindi, bitera nko gutembera kubeshya cyangwa kwangirika kwingenzi kwinjiza.Inenge ya THM ikora ihuza ikorana buhanga irasanzwe
a) Hariho ikibazo cy "indishyi zitari zo": kubera ko umuvuduko wo gusubiza indishyi urenga 40m, harashobora guhungabanya umutekano w "indishyi zitari zo".Kurugero, mugihe ukora ibikorwa byo gukata / gutangiza kumashanyarazi yinjiza, cyangwa gukora imirimo iremereye yo gukata / gutangiza ibikorwa kumpande zo hejuru no hepfo yinjiza UPS, biroroshye gutera "indishyi zo gutandukana".Umucyo waje, utera "impinduka zitunguranye" muri ups power yinjiza ihuza imbaraga.Iyo bikomeye cyane, bizatera "gutembera kubeshya" ya UPS yinjiza.
b) Kwizerwa guke: Kubitanga amashanyarazi adahagarikwa hamwe na pulses 6 + zungurura zikora, igipimo cyo gutsindwa ni kinini, kubera ko umuyoboro wamashanyarazi wogukosora no guhinduranya ari umuyoboro wa IGBT.Ibinyuranye, kuri 12-pulse + passive filter UPS, inductors zizewe cyane hamwe na capacator zikoreshwa mumashusho.
c) Kugabanya imikorere ya sisitemu no kongera ibiciro byo gukora: imikorere ya sisitemu yo kuyungurura ikora ni 93%.Muri connexion ya 400KVA UPS, hasabwa kwishyurwa byuzuye hamwe na 33% byinjijwe murwego rwohejuru rwindishyi zingana, niba amafaranga yumuriro yishyuwe 0.8 yuan kuri KW * hr =, amafaranga yo gukora yishyuwe mugihe cyumwaka umwe naya akurikira
400KVA * 0.07 / 3 = 9.3KVA;gukoresha amashanyarazi buri mwaka ni 65407KW.Hr, naho amafaranga y’amashanyarazi yiyongereye ni 65407X0.8 yuan = 52.000.
d) Ongeraho akayunguruzo gakomeye bihenze cyane: kwinjiza nominal ya enterineti ikora ya filteri ikora 200 kVA UPS ni 303 amps;
Ikigereranyo cya Harmonic igereranijwe: 0.33 * 303A = 100A,
Niba ibyinjijwe bihuza ibirimo biri munsi ya 5%, indishyi zigomba kubarwa byibuze: 100A;
Iboneza ryukuri: Igice cya 100 amp ikora muyunguruzi.Ukurikije ibigereranyo biriho ubu 1500-2000 yuan kuri ampere, igiciro cyose kiziyongera 150.000-200.000, naho ikiguzi cya 6-pulse 200KVA UPS kiziyongera hafi 60% -80%.
Urugero rwa 2
Emera 6-pulse idahagarara itanga amashanyarazi + 5 ya garmonic filter.Niba amashanyarazi adahagarikwa gukosorwa ari ibyiciro bitatu bigenzurwa byuzuye ikiraro cyubwoko bwa 6-pulse ikosora, guhuza byakozwe na rectifier bingana na 25-33% byimiterere yose, kandi nyuma yo kongeramo 5 ya filteri ihuza, ihuza ni yagabanutse kugeza munsi ya 10%.Imbaraga zinjiza ni 0.9, zishobora kugabanya igice cyangiritse cyumuyaga uhuza amashanyarazi.Hamwe nibi bikoresho, ibyinjira byinjira biracyari binini cyane, kandi igipimo cya generator gisabwa kuba kirenze 1: 2, kandi hariho akaga kihishe ko kwiyongera kudasanzwe mubisohoka bya generator.
Icya 3
Gahunda yimpimbano 12-pulse ikoresheje icyiciro cyo guhinduranya transformateur + 6-pulse ikosora igizwe na bibiri-6 byo gukosora hejuru:
a) Ikosora risanzwe 6-pulse ikosora
b) Icyiciro cyahinduwe cya dogere 30 ya transformateur + 6-pulse ikosora
Kugena impimbano 12-pulse ikosora UPS.Ku buso, guhuza ibintu byuzuye byinjiza ibintu bigaragara ko ari 10%.Iboneza bifite ingingo imwe ikomeye yo gutsindwa.Iyo amashanyarazi adahwema gutanga amashanyarazi ananiwe, iyinjiza ihuza imiyoboro ya sisitemu iriyongera cyane, bibangamira cyane umutekano wa sisitemu yo gutanga amashanyarazi.
Ingaruka nyamukuru:
1).Gukata inguni n'ibikoresho by'umwimerere, ibikoresho byose birabura.
2).Niba ikosora rya UPS ryananiwe, izahindurwa muri 6-pulse UPS, kandi ibiyirimo biziyongera cyane.
3).Kandi kugenzura umurongo wa bisi ya DC ni sisitemu yo gufungura-gufungura.Ibyinjira byubu kugabana ntibishobora kuba byiza cyane.Imiyoboro ihuza imitwaro yoroheje izaba nini cyane.
4).Kwagura sisitemu bizagorana cyane
5).Icyiciro-gihinduranya transformateur yashyizweho ntabwo aribicuruzwa byumwimerere, kandi guhuza na sisitemu yumwimerere ntabwo bizaba byiza cyane.
6).Ubuso bwa etage buzaba bunini
7).Imikorere ni 12-15%, ntabwo ari nziza nka 12-pulse UPS.
Icya 4
Emera 12-pulse idahagarara itanga amashanyarazi + 11-itondekanya guhuza akayunguruzo.Niba amashanyarazi adahagarikwa gukosorwa ari ibyiciro bitatu bigenzurwa byuzuye ikiraro cyubwoko bwa 12-pulse ikosora, nyuma yo kongeramo umurongo wa 11 uhuza akayunguruzo, irashobora kugabanuka kugeza munsi ya 4.5%, ishobora ahanini gukuraho burundu ibibi byubwumvikane. Ibiriho ubu kuri power grid, kandi igipimo cyibiciro ni Inkomoko yo kuyungurura ni hasi cyane.
12-pulse UPS + 11 ya garmonique ya filteri yemejwe, ibyinjira byinjira bihuza ni 4.5% (umutwaro wagenwe), naho imbaraga zinjiza ni 0.95.Ubu bwoko bwiboneza nigisubizo cyuzuye kandi cyizewe cyinganda zitanga amashanyarazi ya UPS, kandi gisaba generator ya 1: 1.4.
Ukurikije isesengura ryavuzwe haruguru, gahunda yo kurandura gahunda yo gukuraho 12-pulse ikosora + 11-itondekanya rya harmonic filter hamwe nibikorwa byiza, kwizerwa cyane, imikorere ihamye kandi yizewe, hamwe nibikorwa byiza birasabwa mubikorwa.
