Macluumaadka aasaasiga ah ee isticmaalayaasha
Shirkadda tuurista waalka gate waxay inta badan soo saartaa alaabada waalka.Qalabka khadka wax soo saarka ee shirkadu waxa ka mid ah foorno gelin dhexdhexaad ah oo 2-ton ah, kaas oo ay ku shaqaynayso 2000 kVA (10KV/0.75 kVA) nidaamka sahayda koronto ee xirfadleyda ah.Ku qalabaysan 2 armaajooyinka magdhowga awoodda oo leh mug dhan 600 kVA, 1-ton foorno soo noqnoqosho dhexdhexaad ah, 800 kVA (10KV / 0.4KV) transformers farsamo iyo xirfad leh, iyo golaha magdhowga awoodda leh mugga 300 kVA.Jaantuska nidaamka sahayda korontadu waa sida soo socota:
Xogta hawlgalka dhabta ah
Awoodda muuqata ee foornada soo noqnoqda soo noqnoqda ee dhexdhexaadka ah ee ku qalabaysan 2000KVA Transformer waa 700KVA-2100KVA, awoodda firfircooni waa P=280KW-1930KW, culeyska falcelinta waa Q=687KAR-830KAR, awoodda korontada waa PF=0.4-0.92, iyo hadda shaqeeyaⅰ = 538 A-1660 A, awoodda muuqata ee foornada induction soo noqnoqda dhexdhexaadka ah oo ku qalabaysan 800KVA transformer waa 200KVA-836KVA.Awoodda firfircooni waa P = 60KW-750KW, culeyska falcelinta waa Q=190KAR-360KAR, awoodda korontadu waa PF=0.3-0.9, iyo hadda shaqeeya i=288 A-1200 A. Sababtoo ah golaha magdhowga capacitor lama gelin karo Hawlgalka ( magdhow otomaatig ah ayaa ku guuldareysta, marka capacitor gacanta lagu geliyo, sanqadha capacitor waa mid aan caadi ahayn, wareegtada safraan, capacitor waa la baakadeeyey, saliid daadin, dildilaac, oo aan la isticmaali karin), awoodda bilaha ah ee dhamaystiran Qodobku waa PF=0.78, iyo heerka dulsaarka amaahda guryaha bishiiba waxaa lagu hagaajiyay in ka badan 32,000 yuan.
Falanqaynta Xaaladda Nidaamka Awoodda
Culayska ugu weyn ee soo noqnoqda dhexdhexaadiyaha korontada ee foornada korontada ku shaqeeya waa 6-pulse rectification.Qalabka toosiyaha ayaa AC u beddela DC isagoo soo saaraya tiro badan oo harmonics ah.Isha iswaafajinta ee caadiga ah ee hadda jirta ayaa lagu duraa shabkada, is-hortaagga shabkada waxa ay dhalisaa danab iswada leh, taasoo keenta koronto-shabakareedka Qallooca hadda jira wuxuu saameeyaa tayada sahayda korantada iyo badbaadada hawlgalka, waxay kordhisaa luminta khadka iyo dhimista danabka, waxayna kordhisaa awoodda.Marka bangiga capacitor magdhowga tamarta falcelinta la geliyo shaqada, sababtoo ah is-waafajinta sifada harmonic ee bangiga capacitor waa yar yahay, harmonics badan ayaa lagu soo bandhigay bangiga capacitor, iyo qadarka capacitive hadda Korodhka degdega ah wuxuu si dhab ah u saameeyaa nolosha adeegga.Dhanka kale, marka falcelinta capacitive harmonic ee bangiga capacitor ay la mid tahay falcelinta inductive inductive ee u dhiganta ee nidaamka iyo resonance taxane ah ayaa dhacaya, hadda harmonic ayaa si weyn u weynaaday (2-10 jeer), taasoo keentay in kulayl iyo dhaawac capacitor-ka.Intaa waxaa dheer, harmonics-ku waxay keeni doontaa in mawjada sinusoidal DC ay isbeddelaan, taas oo keenta mowjadda ugu sarreysa ee sawtooth, taas oo ay fududahay in ay keento dheecaan qayb ah walxaha dahaarka.Dheecaan qayb ka mid ah muddada-dheer wuxuu sidoo kale soo dadajin doonaa gabowga walxaha dahaarka oo si fudud u sababi doona dhaawaca capacitor.Sidaa darteed, golaha magdhowga tamarta falcelinta capacitor looma isticmaali karo magdhowga foornada induction soo noqnoqda ee dhexdhexaadka ah, waxaana la doortaa qalab magdhow koronto falgal ah filtar leh oo leh shaqada xakamaynta garaaca wadnaha hadda.
Qorshaha daawaynta magdhowga awooda falcelinta
Yoolalka dowladnimada
Naqshadeynta qalabka magdhawga filtarku waxa uu buuxiyaa shuruudaha xakamaynta iswaafajinta iyo maaraynta awooda falcelinta.
Marka la eego habka hawlgalka ee nidaamyada 0.75KV iyo 0.4KV, ka dib marka la geliyo qalabka magdhowga shaandhada, garaaca garaaca wadnaha ayaa la xakameynayaa, iyo celceliska tamarta bishiiba waxay dhaaftaa 0.95.Gelitaanka wareegga magdhowga shaandhada ma keenayso garaaca garaaca hadda jira ama kor u kaca dhawaaqa iyo qulqulka.

Fikradaha naqshadeynta
Marka loo eego xaalada gaarka ah ee shirkadu, shirkadeena waxay nashqadaysay nidaam tafatiran oo tafatiran oo soo noqnoqonaya foornada soo noqnoqda ee nidaamka shaandhada korontada.Si buuxda uga fiirso qodobka awoodda culayska iyo xakamaynta iswaafajinta, oo ku rakib shaandhada magdhawga korantada yar ee korantada hoose ee dhinaca korantada ee shirkadda 0.75KV iyo 0.4KVInta lagu jiro hawlgalka foornada soo noqnoqda ee dhexdhexaadka ah, qalabka hagaajinta wuxuu soo saaraa 6K + 1 harmonics, iyo taxanaha Fourier waxaa loo isticmaalaa in lagu jajabiyo oo loo beddelo hadda si loo dhaliyo 5 harmonics ee 250HZ iyo 7 harmonics ka sarreeya 350HZ.Sidaa darteed, marka la naqshadeynayo shaandhada aan waxtarka lahayn ee foornada soo noqnoqda, waa in la hubiyaa in wareegga laanta magdhowga filterku uu magdhabo awoodda aan shaqaynayn iyada oo si wax ku ool ah u xakameynaysa is-waafajinta soo noqnoqda ee ka sarreeya 250HZ iyo 350HZ, waxayna kordhisaa qodobka awoodda.
shaqada naqshadeynta
Awoodda guud ee 2-tan foornada induction soo noqnoqda ee dhexdhexaadka ah oo la mid ah 2000 kVA transformer ayaa magdhow laga bilaabo 0.78 ilaa 0.95.Qalabka magdhowga shaandhada wuxuu u baahan yahay in lagu qalabeeyo awood dhan 820 kVA, wuxuuna si toos ah ugu beddelaa 6 kooxood oo awood ah, kuwaas oo mid kastaa uu ku habboon yahay dabaysha dhinaca korantada hoose ee beddelka magdhowga.Awoodda kala-soocidda kala-soocidda waa 60KVAR, kaas oo buuxin kara shuruudaha awoodda kala duwan ee foornada soo-celinta soo noqnoqda ee dhexdhexaadka ah.Awoodda guud ee 1 tan foornada soo noqnoqoshada soo noqnoqda ee dhexdhexaadka ah oo la mid ah koronto-bixiyaha 800 kVA ayaa laga magdhabaa 0.78 illaa 0.95.Qalabka magdhowga shaandhada wuxuu u baahan yahay in lagu qalabeeyo awoodda 360 kVA, kaas oo si toos ah loogu beddeli karo 6 kooxood oo awood ah, awoodda hagaajinta ee darajadu waa 50 kVA, taas oo buuxin karta shuruudaha tamarta kala duwan ee foornada soo noqnoqda ee dhexdhexaadka ah.Naqshadaynta noocan oo kale ah waxay si buuxda u dammaanad qaadaysaa in awoodda la hagaajiyay ay ka sarreyso 0.95.
Falanqaynta saamaynta ka dib rakibidda magdhowga filtarka
Bilowgii Juun 2010, shaandhada foornada inta jeer ee dhexdhexaadka ah ayaa la rakibay oo la hawlgeliyey.Qalabku wuxuu si toos ah ula socdaa isbeddelka culeyska foornada soo noqnoqda ee soo noqnoqoshada dhexdhexaadka ah, gaar ahaan magdhowga culeyska falceliska ah, wuxuuna wanaajiyaa qodobka awoodda.Faahfaahinta sida soo socota:
