Gawaarida roogaga leh (kulul duuban) kiis

Macluumaadka aasaasiga ah ee isticmaalayaasha
Shirkadda birta duubta waxay inta badan soo saartaa bir wareeg ah oo kulul oo leh qeexitaan 16mm ~ φ150mm.Qaybta korontada ee khadka wax soo saarka ee shirkadu waxa wada matoor DC ah oo ku qalabaysan laba transformers 3150KVA.Jaantuska nidaamka sahayda korontadu waa sida soo socota:

kiis-8-1

 

Xogta hawlgalka dhabta ah
Celceliska qodobka awoodda 3150KVA DC matoorka burushka lahayn waa PF = 0.75, hadda shaqeeyaa waa 2650A, garaaca garaaca wadnaha ugu weyn waa 5 jeer, 7 jeer, saamiga beddelka hadda waa 19.5%.

Falanqaynta Nidaamka Awoodda
Culayska ugu weyn ee mashiinka baabuurka burushka aan burushka lahayn ee DC waa 6 ballasts hal-pulse ah.Qalabka ballast-ku wuxuu abuuraa xaddi badan oo garaaca wadnaha hadda jira ee AC, AC, iyo hawlgallada DC.Waa isha caadiga ah ee garaaca wadnaha hadda.Marka la soo geliyo shabkada korantada, hadda is-waafajinta Wadnaha hadda shaqeeya ayaa sabab u ah cilladda sifaha shabakadda korantada, taasoo keentay in uu ka baxo korantada shaqada iyo hadda, taas oo khatar gelinaysa tayada iyo badbaadada hawlgalka Korontada wareejinta, waxay kordhisaa luminta khadka iyo leexashada tamarta shaqada, waxayna saameyn xun ku leedahay shabakadda korontada iyo qalabka korontada laftiisa.

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, qorshe loogu talagalay magdhowga awoodda fal-celinta ee shaandhada shaandhada DC-ka waxaa loo qaabeeyey iyadoo la tixgelinayo awoodda culeyska iyo cadaadiska garaaca wadnaha ee hadda jira, iyo qayb ka mid ah shaandhada hoose ee magdhowga tamarta falcelinta ayaa lagu rakibay 0.4kV hoose. dhinaca danab ee Transformer , si loo xakameeyo hadda garaaca wadnaha, iyo mag load falcelinta, iyo hagaajinta factor awood.Ballastadu waxay soo saartaa 6K-1 garaaca garaaca wadnaha ee habka mashiinka DC bilaa burushka ah, waxayna isticmaashaa hadda cascaded si ay u milaan hadda, iyo hadda kala diri waa ilaa 5250Hz iyo 7350Hz.Sidaa darteed, magdhowga awoodda falcelinta shaandhada waa in loo qaabeeyaa 250Hz, 350Hz iyo soo noqnoqoshooyin kale si loo hubiyo in wareegga magdhowga filterku uu si wax ku ool ah u shaandheyn karo awoodda wax soo saarka garaaca wadnaha ee hadda, wanaajiyo qodobka awoodda, oo uu ka dhigo nidaamka garaaca garaaca hadda inuu u hoggaansamo GB/T3 .

shaqada naqshadeynta
Awoodda guud ee koronto-bixiyaha 3150KVA waxaa laga magdhabaa 0.72 ilaa 0.95.Qalabka magdhowga shaandhada waa in lagu rakibaa 2100KVar, oo loo qaybiyaa 6 kooxood oo ka mid ah furayaasha kontoroolka si loo magdhabo dabaylaha dhinaca cadaadiska hoose ee transformer-ka, iyo hagaajinta mugga ilaa 95KVAR, iyada oo la tixgelinayo shuruudaha awoodda wax soo saarka ee khadka wax soo saarka.

Falanqaynta saamaynta ka dib rakibidda magdhowga filtarka
Bishii Abriil 2011, shaandhada DC-ga ee matoorka magdhowga tamarta falcelinta ayaa la rakibay oo la hawlgeliyay.Qalabku wuxuu si toos ah ula socdaa isbeddelada culeyska ee mootada DC-ga, oo dhab ahaantii shaandheeya isku-dabaynta-sarreeya si loo magdhabo awoodda fal-celiska ah oo loo hagaajiyo qodobka awoodda.Faahfaahinta sida soo socota:

jaantus qaybinta spectrum Harmonic

kiis-8-4

 

Ku shub qaabka Waveform

kiis-8-5

 

Ka dib marka la isticmaalo qalabka magdhowga shaandhada, qalooca isbeddelka qodobka korantadu wuxuu ku saabsan yahay 0.98 (qaybta kor loo qaaday waxay ku saabsan tahay 0.7 marka qalabka shaandhada la saaro)

Hawlgalka load
Awoodda koronto-dhaliyaha 3150KVA wuxuu ka sarreeyaa 0.95, harmonic 5aad waa laga dhimay 510A ilaa 102A, harmonic 7aad waxaa laga dhigay 300A ilaa 60A, tan hadda la isticmaalona waxaa laga dhigay 2650A ilaa 2050A, hoos u dhac 23%.Magdhaw ka dib, qiimaha dhimista korantadu waa WT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=35×{(0.72×3150)/3150}2×0.66≈33 (kw h) Qaaciddada, Pd waa luminta wareegga-gaaban ee transformer-ka, kaas oo ah 35KW, kaydinta kharashyada korantada sannadlaha ah waa 33*20*30*10*0.7*2=280,000 yuan (oo ku salaysan shaqada 20) saacadaha maalintii, 30 maalmood bishii, iyo 10 bilood sannadkii, 0.7 yuan halkii kiilowatt-saac oo koronto ah);Sababo la xiriira dhimista harmonics, biilka korontadu badbaadiyay: Luminta transformer-ka uu keeno hadda is-waafajinta waxay inta badan kordhisaa luminta ferromagnetic iyo luminta naxaasta.Luminta ferromagnetic waxay la xiriirtaa awoodda saddexaad ee iswaafajinta hadda jirta.Injineerinka Guud ahaan, 2% ~ 5% ayaa la qaataa.Culeyska hagaajinta, 2% ayaa la qaataa, taas oo ah, WS=4300*6000*0.7*0.03≈360,000 yuan, taas oo ah, kaydka sanadlaha ee kharashyada korontada waa 28+36=64 (10,000 yuan).

xaaladda factor awood
Xuquuqda guud ee shirkadu waxay ka korodhay 0.72 ilaa 0.95, xuquuqda bilaha waxay ku hadhay 0.96-0.98, mushaharka bishiina wuxuu u dhexeeyay in ka badan 100,000 yuan ilaa 15,000 yuan.
Matoorka DC-gu wuxuu awood u leeyahay inuu xakameeyo garaaca wadnaha ee hadda jira oo uu kabo culeyska tamarta falcelinta, xallinta dhibaatada ciqaabta tamarta falcelinta, kordhinta awoodda wax-soo-saarka ee qalabka wax-soo-saarka, hoos u dhigista luminta magdhowga awoodda firfircoon, kordhinta wax-soo-saarka iyo in la siiyo Shirkaddu waxay soo saartay faa'iidooyin dhaqaale oo muhiim ah, macmiilkuna wuxuu helay maalgelinta mashruuca in ka yar hal sano.Sidaa darteed, shirkaddu aad ayay ugu qanacsan tahay magdhowga tamarta falcelinta ee shaandhada DC-ga ee aan burushka lahayn, waxayna soo bandhigi doontaa macaamiisha qaarkood mustaqbalka.
