Ulwazi olusisiseko lwabasebenzisi
Inkampani yokuphosa ivalve yesango ikakhulu ivelisa iimveliso zevalvu.Isixhobo somgca wemveliso yenkampani sibandakanya iseti ye-2-toni ye-medium-frequency induction furnace, enikwa amandla yi-2000 kVA (10KV/0.75 kVA) inkqubo yonikezelo lwamandla ombane oyingcali.Ixhotyiswe ngeekhabhinethi zembuyekezo ye-2 ye-capacitance kunye nomthamo we-600 kVA, i-toni ye-1 ye-toni ye-intermediate intermediate induction furnace, i-800 kVA (10KV / 0.4KV) i-transformers zobugcisa kunye neengcali, kunye nekhabhinethi yembuyekezo ye-capacitance enomthamo we-300 kVA.Umzobo wenkqubo yonikezelo lwamandla ngolu hlobo lulandelayo:
Eyona datha yokusebenza
Amandla abonakalayo e-intermediate frequency induction furnace exhotyiswe nge-2000KVA transformer yi-700KVA-2100KVA, amandla asebenzayo yi-P=280KW-1930KW, umthwalo osebenzayo yi-Q=687KAR-830KAR, into yamandla yi-PF=0.4-0.92, kwaye yangoku ekusebenzeniⅰ = 538 A-1660 A, amandla abonakalayo e-intermediate frequency induction furnace exhotyiswe nge-800KVA transformer yi-200KVA-836KVA.Amandla asebenzayo yi-P = 60KW-750KW, umthwalo osebenzayo yi-Q=190KAR-360KAR, i-factor factor is PF = 0.3-0.9, kunye nokusebenza ngoku i = 288 A-1200 A. Ngenxa yokuba ikhabhinethi yembuyekezo ye-capacitor ayikwazi ukubekwa. ukusebenza (imbuyekezo ezenzekelayo ihluleka, xa i-capacitor isetyenziswa ngesandla, ingxolo ye-capacitor ayiqhelekanga, i-breaker circuit breaker, i-capacitor ipakishwe, i-oyile ivuza, iqhekekile, kwaye ayinakusetyenziswa), amandla enyanga abanzi. PF=0.78, kunye nenzala yenyanga yemali-mboleko ihlengahlengiswa ibe ngaphezulu kwe-32,000 yeyuan.
Uhlalutyo lwemeko yeNkqubo yaMandla
Owona mthwalo ungundoqo we-intermediate frequency electric furnace rectifier power supply yi-6-pulse rectification.Isixhobo sokuhlaziya siguqula i-AC ibe yi-DC ngelixa sivelisa inani elikhulu lee-harmonics.Umthombo oqhelekileyo we-harmonic we-harmonic yangoku ifakwe kwigridi, kwaye ukungenelela kwegridi kuvelisa i-voltage ye-harmonic, ebangela i-voltage yegridi Ukuphazamiseka kwangoku kuchaphazela umgangatho wobonelelo lwamandla kunye nokhuseleko lokusebenza, kwandisa ilahleko yomgca kunye nokunciphisa umbane, kunye nokwandisa amandla.Xa ibhanki ye-capacitor yembuyekezo yamandla esebenzayo isetyenziswa, ngenxa yokuba i-harmonic i-impedance ye-harmonic yebhanki ye-capacitor incinci, ezininzi ii-harmonics zingeniswa kwibhanki ye-capacitor, kunye nenani le-capacitive yangoku Ukunyuka ngokukhawuleza kuchaphazela kakhulu ubomi bayo benkonzo.Kwelinye icala, xa i-harmonic capacitive reactance yebhanki ye-capacitor ilingana ne-harmonic inductive reactance yenkqubo kunye ne-resonance series, i-harmonic current yandiswa kakhulu (i-2-10 amaxesha), okukhokelela ekugqithiseni kunye nomonakalo i-capacitor.Ukongezelela, i-harmonics iya kubangela ukuba i-DC sinusoidal wave itshintshe, ibangele i-sawtooth peak wave, ekulula ukubangela ukukhutshwa okuyingxenye kwizinto ezikhuselayo.Ukukhutshwa kwexesha elide kuya kukhawulezisa ukuguga kwezinto ezikhuselayo kwaye kubangele lula umonakalo we-capacitor.Ke ngoko, ikhabhinethi yembuyekezo yamandla esebenzayo ye-capacitor ayinakusetyenziselwa imbuyekezo yesithando somlilo esiphakathi, kunye nesixhobo sembuyekezo samandla esicociweyo esine-pulse yangoku yoxinzelelo kufuneka sikhethwe.
Isicwangciso sonyango lwembuyekezo yamandla asebenzayo
Iinjongo zolawulo
Uyilo lwezixhobo zembuyekezo zokucoca luhlangabezana neemfuno zokucinezelwa kwe-harmonic kunye nolawulo loxinzelelo lwamandla asebenzayo.
Ngaphantsi kwendlela yokusebenza ye-0.75KV kunye ne-0.4KV iinkqubo, emva kokuba izixhobo zembuyekezo zokucoca zifakwe ekusebenzeni, i-pulse current icinezelwe, kwaye umthamo wamandla wenyanga udlula i-0.95.Igalelo lesihluzo sembuyekezo yelophu aliyi kubangela ipulse current resonance okanye iresonance overvoltage kunye overcurrent.
Uyilo lulandela iMigangatho

Iingcamango zoyilo
Ngokwemeko ethile yenkampani, inkampani yethu iye yaqulunqa iseti yenkqubo yokucoca amandla aphakathi aphakathi kwe-frequency induction.Qwalasela ngokupheleleyo amandla omthwalo kunye noxinzelelo lwe-harmonic, kwaye ufake iseti yezihluzo zembuyekezo yamandla asezantsi-voltage asebenzayo kwicala lamandla ombane asezantsi kwi-0.75KV yenkampani kunye ne-0.4KV iziguquli zokucinezela i-harmonics, ukubuyisela amandla asebenzayo, kunye nokuphucula into yamandla.Ngethuba lokusebenza kwesithando somlilo esiphakathi, isixhobo sokuhlaziya senza i-6K + 1 i-harmonics, kwaye uchungechunge lwe-Fourier lusetyenziselwa ukubola nokuguqula okwangoku ukuvelisa i-5 harmonics ye-250HZ kunye ne-7 harmonics ngaphezu kwe-350HZ.Ke ngoko, xa kuyilwa imbuyekezo engasebenziyo yesihluzi sesithando somlilo, kufuneka kuqinisekiswe ukuba isihluzi sembuyekezo yesebe lesiphaluka sihlawulela amandla angasebenziyo ngokucinezela ngokufanelekileyo i-harmonics ye-frequencies ngaphezu kwe-250HZ kunye ne-350HZ, kwaye yandisa into yamandla.
umsebenzi woyilo
Umbane obanzi we-2-ton intermediate frequency induction furnace ehambelana ne-2000 kVA transformer ihlawulwa ukusuka kwi-0.78 ukuya malunga ne-0.95.Isixhobo sembuyekezo yesihluzi kufuneka sixhotyiswe ngesakhono se-820 kVA, kwaye siguqule ngokuzenzekelayo sibe ngamaqela ama-6 obuchule, ngalinye lihambelana nokuvunguza kwicala elisezantsi lombane we-transformer yembuyekezo.Umthamo wohlengahlengiso lokuhlelwa kwebakala yi-60KVAR, enokuthi ihlangabezane neemfuno ezahlukeneyo zamandla zesithando somlilo esiphakathi.Umbane obanzi we-1 ton intermediate frequency induction furnace ehambelana ne-800 kVA transformer ihlawulwa ukusuka kwi-0.78 ukuya malunga ne-0.95.Isixhobo sembuyekezo yokucoca kufuneka sixhotyiswe ngomthamo we-360 kVA, enokuthi iguqulwe ngokuzenzekelayo ibe ngamaqela ama-6 omthamo, kwaye umthamo wohlengahlengiso ohleliweyo ngu-50 kVA, onokuhlangabezana neemfuno zamandla ezahlukeneyo zesithando somlilo se-intermediate frequency induction.Olu hlobo loyilo luqinisekisa ngokupheleleyo ukuba amandla ahlengahlengisiweyo angaphezulu kwe-0.95.
Uhlalutyo lwesiphumo emva kokufakwa kwembuyekezo yesihluzi
Ekuqaleni kukaJuni ka-2010, isixhobo sembuyekezo samandla esisebenzayo esiphakathi kwesithando somlilo safakelwa saza sasetyenziswa.Isixhobo silandelela ngokuzenzekelayo utshintsho lomthwalo we-intermediate frequency induction furnace, ihlawulela ngokukodwa umthwalo osebenzayo, kwaye iphucula into yamandla.iinkcukacha ngolu hlobo lulandelayo:
