Macluumaadka aasaasiga ah ee isticmaalayaasha
Shirkadda muhiimka ah ee qalabka dhismaha iyo qalabka dhismaha waxay si badbaado leh u soo saartaa birta wareegsan ee PC, taarikada dhamaadka, khadadka galvanized, khadadka alaabta la bedelay, 30MnSi iyo badeecooyin kale.Shirkaddu waxay leedahay 4 khadadka wax soo saarka oo aad u wanaagsan, kuwaas oo adeegsada kuleyliyaha soo noqnoqda dhexdhexaadka ah iyo matoorada wadida soo noqnoqda ee DC, oo leh 2000KVA2 (oo lagu dabaqay tandem).Jaantuska nidaamka sahayda korontadu waa sida soo socota:
Xogta hawlgalka dhabta ah
Awoodda gaarka ah waa PF = 0.82, hadda shaqeeyaa waa 2250A, garaaca garaaca wadnaha ugu weyn waa 5 jeer, wadarta hadda jirtana waxay noqotaa 23.6%.
Falanqaynta Xaaladda Nidaamka Awoodda
Culayska ugu weyn ee foornada soo noqnoqoshada soo noqnoqda ee dhexdhexaadka ah, foornada soo noqnoqda ee soo noqnoqoshada dhexdhexaadka ah iyo sahayda korontadu hagaajinayso waa 6-aad ee garaaca wadnaha.Qalabka toosiyaha ayaa soo saara wax badan oo garaaca wadnaha ah marka uu AC hadda u beddelayo danab AC.Xakamaynta hadda jirta ee lagu soo rogay shabkada korantada waxay sababi kartaa garaaca garaaca korantada shaqaynaysa ee hadda jirta, taasoo keentay isbedbedelka korantada shaqaynaysa iyo hadda, khatar gelinaysa tayada iyo badbaadada hawlgalka ee wareejinta sahayda korantada, kordhinta khasaaraha khadka iyo leexashada korantada shaqaynaysa, iyo saamayn taban qalabka korontada ee warshadda korontada lafteeda.
Isku-xidhka kumbuyuutarka ee barnaamijka kontoroolka (PLC) wuxuu u nugul yahay qalloocinta is-waafajinta ee tamarta shaqada ee sahayda beddelka.Waxaa guud ahaan lagu qeexay in wadarta guud ee garaaca wadnaha hadda shaqeeya ee khasaaraha jireed (THD) uu ka yar yahay 5%, iyo garaaca wadnaha shakhsi ahaaneed ee hadda shaqeeya Haddii heerka jirku uu aad u sarreeyo, qaladka hawlgalka ee nidaamka xakamaynta ayaa laga yaabaa inuu keeno hakad wax soo saarka ama hawlgalka, taasoo keentay shil mas'uuliyad wax-soo-saar oo weyn.Sidaa darteed, magdhowga korantada falcelinta yar ee shaandhada leh shaqada shaandhada hadda jirta ee garaaca wadnaha waa in loo adeegsadaa si loo magdhabo culeyska falcelinta iyo hagaajinta qodobka awooda.
Shaandhayso qorshaha daaweynta magdhowga awooda falcelinta
Yoolalka dowladnimada
Naqshadeynta qalabka magdhawga filtarku waxa uu buuxiyaa shuruudaha xakamaynta iswaafajinta iyo maaraynta awooda falcelinta.
Marka la eego habka 0.4KV ee habka hawlgalka, ka dib marka la geliyo qalabka magdhowga shaandhada, garaaca garaaca wadnaha ayaa la xakameynayaa, celceliska tamarta bishiiba waa 0.92.
Dhawaaqa is-waafajinta ee nidaamka sare leh, kororka dhawaaqa, iyo qulqulka xad dhaafka ah ee ay sababto isku xidhka wareegga laanta magdhowga filter ma dhici doonto.

Fikradaha naqshadeynta
Marka loo eego xaaladda gaarka ah ee shirkadda, shirkaddu waxay dejisay qorshe faahfaahsan oo ah magdhowga tamarta falcelinta foornada dhexdhexaadinta soo noqnoqda iyo sahayda korontadu.Iyadoo la tixgalinayo culayska culeyska iyo shaandhada hadda jirta ee garaaca wadnaha, shaandhada shaandhada hoose ee magdhowga korantada, shaandhaynta hadda garaaca wadnaha, magdha culayska firfircoonida, oo wanaajisa qodobka awooda.
Geedi socodka oo dhan ee foornada soo noqnoqoshada soo noqnoqda ee dhexdhexaadka ah iyo beddelaha, qaybaha guud waxay soo saaraan qulqulka garaaca wadnaha ee 6K, kuwaas oo loo beddelo iyadoo loo eegayo socodka hadda jira ee taxanaha Fourier, iyo qulqulka garaaca wadnaha ee dabeecadda ayaa laga soo saaraa 5250Hz iyo 7350Hz.Sidaa darteed, marka la naqshadeynayo magdhowga tamarta falcelinta shaandhada, bilowga jilicsan iyo nidaamka naqshadaynta soo noqnoqda ee 350Hz waxay hubisaa in wareegga korantada magdhowga filterku uu yahay mid macquul ah waafaqsan GB/T3 si wadajir ah.
shaqada naqshadeynta
Awoodda bilawga jilicsan iyo jilicsan ee koox kasta oo ah 2000KVA Transformers waxaa laga magdhabaa 0.8 ilaa 0.95, garaaca garaaca 5th hadda waa la dhimay 420A ilaa 86A, garaaca garaaca wadnaha 7th waxaa laga dhimay 230A ilaa 46A, iyo qalabka magdhowga filter wuxuu u baahan yahay lagu rakibo mugga 1060KVar.Filterku wuxuu u qaybsan yahay 6 kooxood, magdhowga shaandhada waxaa loo isticmaalaa bilawga jilicsan iyo ballast korantada wareejinta, filtarka ayaa loo qaybiyaa 5 jeer, 7 jeer, iyo wareegga bixinta korantada magdhowga filter si toos ah ayaa loo rogaa si loo tixgeliyo foornada soo noqnoqoshada dhexdhexaadka ah. shaandheynta iyo awoodda falcelinta ee bixinta nidaamka magdhowga.
Naqshadani waxay si buuxda u hubinaysaa in xakamaynta iswaafajinta ay u hoggaansan tahay heerka qaran ee GB/T 14549-93, oo wuxuu hagaajiyaa qodobka awoodda foornada soo noqnoqda ee dhexdhexaadka ah iyo beddelaha soo noqnoqda ee ka sarreeya 0.95.Sida hoos ka muuqata:
Falanqaynta saamaynta ka dib rakibidda magdhowga filtarka
Bishii Juun 2010, foornada inta jeer ee dhexdhexaadka ah iyo shaandhada beddelayaasha soo noqnoqda ayaa la rakibay oo la hawlgeliyey.Qalabku wuxuu si toos ah ula socdaa isbeddelada culeyska ee foornada soo noqnoqda ee dhexdhexaadka ah iyo beddelaha soo noqnoqda, oo dhab ahaantii meesha ka saaraya hawo-qaadka sare si loo magdhabo awoodda falcelinta loona hagaajiyo qodobka awoodda.Faahfaahinta sida soo socota:
jaantus qaybinta spectrum Harmonic
Ku shub qaabka Waveform
Ka dib marka la isticmaalo aaladda magdhowga shaandhada, qalooca qodobka awoodda ayaa isbeddelaya ka dib markii qalabka magdhowga shaandhada la geliyo qiyaastii 0.97 (qaybta kor loo qaaday waxay ku saabsan tahay 0.8 marka qalabka shaandhada la saaro)
Hawlgalka load
Hadda la isticmaalo qayb kasta oo ah 2000KVA Transformers waxaa laga dhimay 2250A ilaa 1860A, hoos u dhac 17% ah;magdhow ka dib, qiimaha dhimista korontada waa WT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=24 ×{(0.85×2000)/2000}2×0.4≈16 (kw h) Qaaciddada, Pd waa luminta wareegga-gaaban ee transformer-ka, kaas oo ah 24KW, iyo kaydinta kharashyada korontada sannadlaha ah waa 16*20*30*10*0.7=67,000 yuan (sida ku cad shaqada 20 saacadood a maalin, 30 maalmood bishii, 10 bilood sannadkii, 0.7 yuan halkii kilowatt-saac);biilasha korontadu waxay badbaadisay hoos u dhigista is-waafajinta awgeed: Khasaaraha ka dhasha is-waafajinta hadda taagan ee beddelka ayaa inta badan kordhinaysa khasaaraha ferromagnetic iyo luminta naxaasta.Guud ahaan, 2% ~ 5% waxaa lagu qaataa injineernimada, 2% waxaa loo qaataa culeys la saxay, taas oo ah: WS=2000*6000*0.7*0.02≈168,000 yuan, yacni, Save koronto sanadlaha ah (6.7+16.8)* 2=47 (10,000 yuan).
xaaladda factor awood
Xuquuqda guud ee shirkadda ayaa laga kordhiyey 0.8 ilaa 0.95, waxaana qodobka xuquuqaha bishiiba lagu ilaaliyay 0.96-0.98, iyada oo abaal marin dheeraad ah lagu siinayo 6,000-10,000 yuan.
Isku soo wada duuboo, magdhowga korantada yar-yar ee shaandhada MFF iyo VF waxay leedahay shaandhooyin aad u fiican waxayna magdhowdaa culeysyada falcelinta, waxay xallisaa dhibaatada ciqaabta tamarta falcelinta, waxay kordhisaa awoodda wax soo saarka ee transformers, waxay hagaajinaysaa tayada korantada, waxay wanaajisaa sifooyinka korantada codsatay. qalabka, oo waxay yaraynaysaa magdhowga tamarta firfircoon Isticmaalka, hagaajinta hufnaanta, faa'iidooyinka dhaqaale ee muhiimka ah ee shirkadda, maalgashiga heerka soo celinta wax ka yar hal sano macaamiisha, iwm. Sidaa darteed, shirkadu waxay aad ugu qanacsan tahay magdhowga foornada soo noqnoqda ee dhexdhexaadka ah. iyo shaandhada falcelinta falcelinta ee sahayda korontadu, waxayna soo bandhigi doontaa macaamiil badan mustaqbalka.
