Goobahee ayaa sahayda korontada ee UPS si weyn loo isticmaalaa?
Qalabka nidaamka korontada ee UPS waa nooca ugu horreeya ee qalabka macluumaadka, inta badan loo isticmaalo ilaalinta amniga nidaamyada macluumaadka kombiyuutarka, nidaamyada isgaarsiinta, xarumaha shabakada xogta moobiilka, iwm. In warshadaha xogta weyn, warshadaha xogta weyn, gaadiidka waddooyinka, warshadaha maaliyadda. silsilad, silsilad warshadaha aerospace, iwm Sida qalab durugsan ee nidaamka macluumaadka kombiyuutarka, nidaamka isgaarsiinta iyo xarunta xogta, sahayda korontada aan kala go'in ayaa door aad u muhiim ah ka ciyaara ilaalinta xogta kombiyuutarka, hubinta xasiloonida danab koronto iyo inta jeer, hagaajinta tayada shabaqlaha korantada, iyo ka hortagga burburka degdegga ah ee korantada iyo cilladda korantada lama filaanka ah ee waxyeelada u geysata isticmaalayaasha.door.
Nooca labaad ee awoodda warshadaha qalabka nidaamka korontada ee UPS waxaa inta badan loo isticmaalaa beeraha korontada, birta, biraha non-ferrous, dhuxusha, petrochemical, dhismaha, daawada, baabuurta, cuntada, military iyo beeraha kale ee warshadaha qalabka korontada. , hubinta in dhammaan qalabka korontada ku shaqeeya nidaamka warshadaha, fogfog Isku hallaynta korontada automation warshadaha ee AC iyo DC qalabka korontada aan kala go 'lahayn sida qalabka nidaamka fulinta, xidhiidhka sare-voltage korontada, ilaalinta relay, qalabka si toos ah, iyo qalabka signalada.Sahay koronto oo aan kala go' lahayn oo heer wershadeed ah ayaa ah alaab heersare ah oo ka mid ah sahayda koronto ee aan kala go'ayn.Waxay ku lug leedahay tignoolajiyada korantada korantada ee tamarta sare (laga yaabee heerka megawatt) beddelka tamarta, nidaamka xakamaynta dhijitaalka ah, tignoolajiyada taxanaha AC, tignoolajiyada xakamaynta garaaca wadnaha ee hadda jira, tignoolajiyada wax soo saarka awoodda sare ee tamarta, iwm. Sida cad, shirkadaha tamarta caadiga ah ma geli karaan warshadaha this.Kaliya shirkadaha leh awoodda sare ee tignoolajiyada elektiroonigga ah iyo taxane ah horumarinta wax soo saarka, wax soo saarka iyo awoodaha adeegga, iyo ururay wax soo saarka warshadaha u dhiganta iyo waayo-aragnimada codsiga, samayn karaa shaqo wanaagsan in design ee warshadaha korontada aan kala go'a lahayn hababka sahayda , Wax soo saarka iyo iibinta suuqa. adeegyada.
Waqtigan xaadirka ah, waxaa jira afar qorshe oo loogu talagalay xakamaynta iswaafajinta ee cabbirka weyn ee UPS
qorshaha 1.
6-pulse UPS+ shaandheyn heer sare ah oo firfircoon, gelinta hamuunta-dalabka sare ee hadda <5% (load)Habkani waxa uu ka dhigayaa tilmaame wax-soo-gelinta mid aad u wanaagsan, laakiin tignoolajiyadeedu ma qaan-gaadhin, waxaana jira dhibaatooyin ay ka mid yihiin magdhowga khaladka, magdhowga xad-dhaafka ah, iwm., kuwaas oo sababa sida jabsi been ah ama dhaawac soo gaadha furaha muhiimka ah.Cilladaha farsamada shaandhada harmonic firfircoon ee THM waa wax caadi ah
a) Waxaa jirta dhibaato ah "magdhow been abuur ah": sababtoo ah xawaaraha jawaab celinta magdhowgu wuxuu dhaafaa 40ms, waxaa jira khatar badbaado oo suurtagal ah "magdhow been ah".Tusaale ahaan, marka la fulinayo hawlgallada goynta/gudbinta ee sahayda korantada, ama samaynta hawlo-goynta/gubida hawl-gallada culus ee dhinacyada sare iyo kuwa hoose ee gelinta UPS, way fududahay in la keeno "magdhow leexashada".Iftiinku wuu shiday, isaga oo keenay "isbeddel degdeg ah" ku yimid tamarta kor u kaca ee hadda gelinta.Marka ay ka sii daran tahay, waxay keeni doontaa "jaro been ah" beddelka UPS.
b) Kalsoonida hoose: Qalabka korontada ee aan kala go'a lahayn ee leh 6 garaaca + filtarrada firfircoon, heerka guuldaradu aad ayuu u sarreeyaa, sababtoo ah tuubada korantada ee hagaajinteeda iyo beddelkeeda waa tuubo IGBT.Taa lidkeeda, 12-pulse + filter dadban UPS, inductors iyo capacitors aadka la isku halleyn karo ayaa loo isticmaalaa miirayaasha.
c) Yaraynta hufnaanta nidaamka iyo kordhinta kharashyada hawlgalka: hufnaanta nidaamka ee filtarrada firfircoon waa qiyaastii 93%.Isku xirka 400KVA UPS ee isku midka ah, iyada oo la raacayo shuruudda dallacaadda buuxda iyo 33% soo gelida dalabka sare ee magdhowga iswaafajinta, haddii khidmadda korantada lagu bixiyo 0.8 yuan per KW*hr=, kharashyada hawlgelinta ee la bixiyo hal sano gudaheed waa sida soo socota
400KVA*0.07/3=9.3KVA;isticmaalka korontadu sanadkii waa 65407KW.Hr, khidmadda korontaduna waa 65407X0.8 yuan=52,000 yuan.
d) Ku darista shaandhada firfircooni aad bay qaali u tahay: gelinta hadda jirta ee shaandhada firfircoon ee 200 kVA UPS waa 303 amps;
Qiyaasta hadda la isku raacsan yahay: 0.33*303A=100A,
Haddi waxa ku jira is-waafajinta hadda ka yar tahay 5%, gunnada hadda waa in loo xisaabiyaa ugu yaraan: 100A;
Habaynta Dhabta ah: Qayb ka kooban 100 amp filtarrada firfircoon.Marka loo eego qiyaasta hadda ee 1500-2000 yuan ee ampere, wadarta kharashka wuxuu kordhin doonaa 150,000-200,000 yuan, iyo kharashka 6-pulse 200KVA UPS wuxuu kordhin doonaa qiyaastii 60% -80%.

Qabo 6-pulse koronto aan kala goyn karin + shaandhada 5aad ee harmonicHaddii hagaajinta sahayda korontada ee aan kala go'a lahayn ay tahay saddex-waji oo si buuxda loo kontaroolay nooca buundada 6-pulse rectifier, harmonics-yada uu soo saaray hagaajintu waxay ku xisaabtamaan ku dhawaad 25-33% dhammaan harmonics, iyo ka dib marka lagu daro shaandhada 5-aad ee harmonic, iswaafajinta waa hoos loo dhigay 10%.Cunsurka korantada wax gelinta waa 0.9, kaas oo qayb ahaan yarayn kara waxyeelada hadda isku-dhafan ee shabagga korantada.Qaabayntan, is-waafajinta hadda jirta ee wax gelinta ayaa weli ah mid aad u weyn, saamiga awoodda koronto-dhaliyaha ayaa looga baahan yahay inuu ka weynaado 1: 2, waxaana jirta khatar qarsoon oo kororka aan caadiga ahayn ee soosaarka koronto-dhaliye.
Doorashada 3
Nidaamka been abuurka ah ee 12-pulse iyadoo la adeegsanayo is beddelka beddelka wejiga + 6-pulse rectifier wuxuu ka kooban yahay laba hagaajin oo 6-pulse ah:
a) Halbeeg toosiye 6-pulse ah
b) Transformer 30-degree ah oo weji-wareejiyay + 6-xabad toosiye
La habeeyay ee been abuur ah 12-pulse rectifier UPS.Dusha sare, is-waafajinta qulqulka culeyska buuxa ee hadda wuxuu u muuqdaa inuu yahay 10%.Qaabayntani waxa ay leedahay hal dhibic oo halis ah oo fashil ah.Marka sahayda korontada ee aan kala go'a lahayni ay xumaato, soo galitaanka harmonic ee nidaamka ayaa si aad ah u kordheysa, taasoo khatar gelinaysa badbaadada nidaamka sahayda korontada.
Khasaaraha ugu weyn:
1).Goynta geesaha iyo walxaha qalabka asalka ah, qalab dhan oo qalab ah ayaa maqan.
2).Haddii hagaajinta UPS uu guuldareysto, waxaa loo bedeli doonaa 6-pulse UPS, iyo nuxurka iswaafajinta ayaa si aad ah u kordheysa.
3).Xakamaynta khadka baska ee DC waa nidaam kontorool oo furan.Qaybsiga hadda jira ma noqon karo mid aad u wanaagsan.Dabeecadda iswaafajinta ee culeyska fudud weli aad buu u weynaan doonaa.
4).Balaadhinta nidaamka aad bay u adkaan doontaa
5).Beddelka isbeddelka wejiga ee lagu rakibay maaha badeecadii asalka ahayd, iyo ciyaarta la socota nidaamka asalka ah ma noqon doonto mid aad u wanaagsan.
6).Aagga sagxadda ayaa ahaan doona mid aad u weyn
7).Waxqabadku waa 12-15%, taas oo aan u fiicnayn sida 12-pulse UPS.
Doorashada 4
Qabo 12-pulse koronto aan kala goyn karin + 11-dalbasho filter harmonic.Haddii dib-u-habeeyaha korontada ee aan kala go'a lahayn uu yahay saddex-waji oo si buuxda loo xakameeyo-nooca 12-pulse rectifier, ka dib marka lagu daro shaandhada 11-aad ee harmonic, waxaa lagu yarayn karaa in ka hooseyso 4.5%, taas oo asal ahaan si buuxda u baabi'in karta waxyeellada is-waafajinta. Waxyaabaha hadda jira ee shabagga korantada, iyo saamiga qiimuhu waa filter isha aad ayuu uga hooseeyaa.
12-pulse UPS+11th filter harmonic waa la qaatay, iswaafajinta hadda jirta waa 4.5% (loader la qiimeeyay), iyo qodobka awooda wax gelinta waa 0.95.Qaabaynta noocaan ah waa xal dhamaystiran oo la isku halayn karo oo loogu talagalay warshadaha tamarta UPS, waxayna u baahan tahay mugga koronto-dhaliye ee 1: 1.4.
Iyada oo ku saleysan falanqaynta kor ku xusan, nidaamka baabi'inta iswaafajinta ee 12-pulse rectifier + 11th-order harmonic filter oo leh waxqabad wanaagsan, kalsooni sare, waxqabad xasilloon oo la isku halleyn karo, iyo waxqabadka qiimaha wanaagsan ayaa lagula talinayaa ficil ahaan.
