Macluumaadka aasaasiga ah ee isticmaalayaasha
Shirkad balaastig ah ayaa inta badan soo saarta xayaysiisyada gudaha iyo dibaddaba maro khafiif ah, maro buufin ah, iyo alaabada filimada duuban ee PVC.Qalabka wax soo saarka ee shirkaddu waxay leedahay afar qaybood oo ballaaran oo PVC ah oo duuban khadadka wax soo saarka, oo leh xariiqda wax soo saarka ee buufinta iyo laba khadadka wax soo saarka ee sawirada, Qeybta korantadu waxay qabataa matoorka beddelka soo noqnoqda iyo mashiinka DC, 1000KVA, 2 qaybood oo ah 1250KVA transformers, 2 800KVA Transformers, 1 set oo ah 630KVA Transformers, iyo saxan magdhow ah ayaa lagu dhejiyay dhinaca korantada hoose ee transformerka.Jaantuska nidaamka sahayda korontadu waa sida soo socota:
Xogta hawlgalka dhabta ah
Transformer 2000KVA oo ku qalabaysan foornada soo noqnoqda dhexdhexaadka ah iyo inverter ayaa leh awoodda ugu badan ee 1500KVA, awoodda dhabta ah ee dhabta ah waa PF=0.82, hadda shaqeeyaa waa 2250A, harmonics inta badan waa 5th iyo 7th, iyo wadarta heerka qallooca ee hadda jira waa 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
Qayb kasta oo ah 2000KVA Transformer waxay u dhigantaa foornada soo noqnoqda ee dhexdhexaadka ah iyo awoodda guud ee rookaha waxaa laga magdhabaa 0.8 ilaa 0.95 ka sarreeya, harmonic 5th ayaa laga dhimay 420A ilaa 86A, iyo harmonic 7th ayaa laga dhimay 230A ilaa 46A.Qalabka magdhowga shaandhada wuxuu u baahan yahay in lagu rakibo awood dhan 1060KVar.Waxaa loo qaybiyaa 6 kooxood oo awood u leh beddelashada tooska ah, oo u dhiganta foornada soo noqnoqda dhexdhexaadka ah, magdhowga shaandhada korantada inverter, oo loo qaybiyay 5 jeer, waqtiyada 7 iyo magdhowga ganaaxa shaandhada shaandhada wadada tooska ah, si ay ula kulmaan foornada inta jeer ee dhexdhexaadka ah, filter filter iyo Awood fal-celin Shuruudaha naqshadaynta 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 ku cad shaxanka hoose: Falanqaynta saamaynta ka dib rakibidda magdhowga shaandhada
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)
Shuruudaha hawlgalka load hadda la isticmaalo qayb kasta oo ah 2000KVA Transformers waa laga dhimay 2250A ilaa 1860A, hoos u dhac ah 17%;hoos u dhaca qiimaha korontada ka dib magdhow waa WT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=24×{(0.85×2000)/2000}2×0.4≈16 (kw h) Qaabka loo yaqaan 'Transformer' waa 24KW oo luminaya muddo-gaaban, qarashka korontadu sanad walba keydsanaayo waa 16*20*30*10*0.7=67,000 (iyadoo ku saleysan shaqada 20 saac maalintii). , 30 maalmood bishii, iyo 10 bilood sannadkii, 0.7 yuan halkii kiilowatt-saac oo koronto ah);biilka korantada ee la badbaadiyay iyadoo ay ugu wacan tahay hoos u dhaca is-waafajinta: Khasaaraha ka dhasha qulqulka is-waafajinta ee Transformers waxaa inta badan sabab u ah khasaaraha ferromagnetic oo kordhay iyo luminta naxaasta iyo luminta ferromagnetic waxay la xiriiraan awoodda saddexaad ee is-waafajinta hadda taagan.Guud ahaan, 2% ~ 5% waxaa lagu qaataa injineernimada, iyo 2% waxaa loo qaataa culeyska hagaajinta, taas oo ah: WS=2000*6000*0.7*0.02≈168,000 yuan, Taasi waa, biilka korontadu waa la badbaadin karaa sanadka oo dhan. (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.
