Waqtigan xaadirka ah, awoodda xakamaynta iswaafajinta ugu wanaagsan ee suuqa waa taxanaha APF ee shaandhada firfircoon ee hooseeya ee ay soo saartay oo ay soo saartay Hongyan Electric.Tani waa qayb koronto ah oo ku salaysan la socodka hadda iyo tignoolajiyada hordhaca ah ee hadda jirta.Qaybta hadda is-waafajinta ah ee la magdhabayo waxaa lagu helaa iyadoo loo eegayo qaabka mowjadda hadda jirta ee culayska la socodka.Iyada oo la xakameynayo kicinta IGBT, tignoolajiyada beddelka qaabeynta garaaca garaaca wadnaha ayaa loo isticmaalaa in lagu soo bandhigo harmonics, qaybaha falcelinta iyo qulqulka jihada ka soo horjeeda nidaamka qaybinta awoodda si loo gaaro saameynta ciribtirka harmonics.Shaandheeyaha waxtarka leh wuxuu dhaafi karaa qiyaastii 95%, taas oo hagaajinaysa qodobka badbaadada iyo isku halaynta nidaamka bixinta korantada, iyo gaaritaanka hadafka ilaalinta deegaanka, badbaadinta tamarta iyo kor u qaadida tayada.
Tixgelinta shuruucda shirkadda tamarta ayaa ah dariiqa muhiimka ah ee shirkadaha si ay u hirgeliyaan maamul is-waafajin ah.Shirkadda korontadu waxay ku qasban tahay inay soo saarto tamar koronto oo tayo leh macaamiisha injineernimada korontada.Sidaa darteed, shirkadda korontadu waxay soo jeedinaysaa shuruudaha xakamaynta garaaca wadnaha ee hadda jira isticmaalayaasha kuwaas oo laga yaabo inay wasakheeyaan shabakadda.Maaddaama shirkado badan oo badan ay u baahan yihiin tayada sare ee tamarta, shirkadaha korantadu waxay soo bandhigi doonaan shuruudo adag macaamiisha injineernimada korontada.
Guud ahaan marka la hadlo, kontoroolka is-waafajinta ee qayb ahaan iyo kantaroolka is-waafajinta dhexe ayaa la isku dari karaa si loo soo saaro xal kharash-ku-ool ah.Culayska isha iswaafajinta leh ee leh awood sare (sida foornooyinka soo noqnoqda ee dhexdhexaadka ah, bilawga jilicsan, iwm.).), iyadoo la isticmaalayo filtarrada iswada ee danabka aadka u sarreeya ee kontoroolka wada shaqaynta deegaanka si loo yareeyo is-waafajinta hadda la soo galiyay shabagga korantada.Culaysyada nidaamka kala duwan ee leh awood yar iyo awood qaybsan, maamul midaysan waa in lagu sameeyaa baska nidaamka.Waxaad isticmaali kartaa shaandhada firfircoon ee Hongyan ama filtarka dadban.
Sifaynta iyo warshadaha kiimikaad ee biraha aan birta ahayn waa inay isticmaalaan habka korantada, sidaas awgeed dib-u-habeyn awood sare leh waa lagama maarmaan.Dadku waxay tusaale ahaan u qaataan wax-soo-saarka haydarojiin-ka biyo-koronto.Dadku waa inay dejiyaan isku beddelka beddelka iyo kabnada toosiyaha thyristor.Habka ballastka waa nooc xiddigood oo laba jibbaaran oo laba jibbaaran.Hadafka beddelka ah ee la soo saaray waxaa loo isticmaalaa unugga korantada: 10KV/50HZ-rectifier Transformer-phase danab 172V*1.732 wajiga danab 2160A-rectifier cabinet-AC 7200A/179V-electrolytic cell.Transformer Rectifier: Xiddig isku dheeli tiran oo dheellitiran oo lix-waji ah ama saddex-waji shan-gees ah oo laba-laaban leh.Mugga laynka wax-soo-gelinta: 1576 kVA mugga dhinaca waalka 2230 kVA mugga nooca 1902 kVA thyristor rectifier cabinet K671-7200 A/1179 volts (afar qaybood guud ahaan).Qalabka dib-u-hagaajinta ayaa keeni doona qulqulo badan oo qulqulaya, taas oo si weyn u khatar gelin doonta tayada korantada korantada.
Qalabka hagaajinta ee saddex-waji buuxa ee buundada 6-pulse rectifier-ka awoodda sare leh, is-waafajinta-sarreeya ee ay soo saartay hagaajintu waxay ku xisaabtamaysaa 25-33% wadarta isku-darka nidaamka sare, taas oo dhaawac weyn u geysan doonta korantada, iyo dabeecadaha hab-sarcaadka sarreeya ee la soo saaro waa 6N ± 1 jeer, taas oo ah, waqtiyada dabeecadda dhinaca valve waa 5th, 7th, 11th, 13th, 17th, 19th, 23rd, 25th, iwm, iyo 5th iyo 7th sare. Qaybaha iswaafajinta waxaa soo saara barta PCC ee dhinaca shabakada weyn ee dabeecadda sare ee is-waafajinta waxay ku yaalaan isla dhinaca waalka, oo ka mid ah nidaamka 5aad waa weyn yahay, iyo amarka 7aad ayaa hoos u dhacaya.Hawlgalka isbarbardhigga ah ee kooxda beddelka toosiyaha ee leh weji-wareejin-wareejin ayaa sameyn kara 12 garaac, waqtiyada dabeecadda dhinaca shabakadu waa 11 jeer, 13 jeer, 23 jeer, 25 jeer, iwm, 11 jeer iyo 13 jeer waa ugu weyn.
Haddii aysan jirin qalab shaandhayn ah oo lagu rakibay dhinaca shabakada ama dhinaca waalka, wadarta garaaca garaaca wadnaha ee hadda lagu duray shabkada waxay dhaafi doontaa heerka warshadaha ee shirkadeena, iyo dabeecada iswaafajinta ee hadda lagu duray transformer-ka ugu weyn waxay sidoo kale dhaafi doontaa qiimaha xakamaynta heerka warshadaha shirkadeena.Is-waafajinta sare waxay sababi doontaa fiilooyinka qaybinta, kuleylinta beddelka, aaladaha magdhowga ee aan shaqaynayn oo aan ka bixi karin warshadda, xaalufka tayada isgaadhsiinta, cilladaha furaha hawada, koronto-dhaliyaha iyo xaalado kale oo xun.
Guud ahaan, shabakada awoodda weyn ee nidaamka, dabeecadda iswaafajinta sare ayaa laga saari karaa iyada oo la adeegsanayo qalabka filterka (fc), iyo yoolalka maamulka waa la buuxin karaa.Marka laga hadlayo nidaamka korantada yar, hadafka wax ka qabashada isku-dhafka sare waa mid sarreeya.Marka lagu daro rakibidda qalab shaandheyn dadban oo awood weyn leh, shaandhada firfircoon ee awoodda yar (apf) ayaa sidoo kale loo isticmaali karaa si loo gaaro cabbirrada tayada tayada leh ee dalbanaya.Nidaamyada rakibaadda hagaajinta ee leh habab isku xirnaan oo kala duwan, rakibaadaha magdhawga shaandhaynta xirfadaheena waxay leeyihiin nashqado bartilmaameed oo kala duwan.Imtixaanka goobta ka dib, waxay u "habayn karaan" macaamiisha waxayna dooran karaan qorshe daaweyn oo ku habboon xaaladda dhabta ah ee goobta.
