Dareen-celinta ay sababtay isku-xidhka gaaban ee foornooyinka waaweyn iyo kuwa dhexe ee hoostooda hoostooda waxay ka dhigan tahay 70% falcelinta hawlgalka ee foornada kuleylka.Shabakadda gaaban ee foornada arc ee hooseysa waxaa loola jeedaa ereyga guud ee noocyada kala duwan ee cadaadiska hoose iyo korantada sare ee hadda jira ee ka soo baxa kooxda hoose ee dhamaadka foornada korantada ilaa heerka korantada.Inkasta oo dhererka shabaqyada gaaban ee foornada arc ee hooseysa aysan ahayn mid weyn, iska caabiyeyaasha shabakada gaaban iyo falcelinta ayaa saameyn weyn ku leh qalabka foornada arc ee hoostiisa.Qaab dhismeedkiisa oo dhib badan awgeed, hadda maraa wuxuu gaaraa boqollaal kun oo amperes ah.Sababtoo ah qiimaha falcelinta wareegga gaaban guud ahaan waa 3 ilaa 6 jeer ka caabiyaha, falcelinta wareegga gaaban ayaa inta badan go'aamisa waxtarka, qodobka awoodda iyo heerka isticmaalka tamarta foornada arc ee hoos quustay.
Habka magdhowga gacanta ee caadiga ah waa in lagu xidho bangiga capacitor magdhowga taxanaha ah iyo baska korantada sare leh ee dhinaca hore ee isbedbedelka foornada quusta, taas oo ah, magdhow-sare.Maaddaama saamaynta magdhowgu ay ka faa'iidaysan karto oo keliya xariiqda ka hor marinka marinka iyo dhinaca korantada korantada ee nidaamka korantada, nidaamka korantada wuxuu buuxin karaa shuruudaha la xiriira qodobka korantada ee xariiqda culeyska, laakiin ma magdhabi karo dabaylaha beddelka , Shabakad gaaban, iyo electrodes foornada miinada.Awoodda falcelinta ee dhammaan wareegyada hoose ee hooseeya iyo kuwa sare ee hadda jira, taas oo ah, qalabku kama faa'iidaysan karo kororka wax soo saarka foornada miinada iyo hoos u dhigista isticmaalka tamarta iyo isticmaalka miinada.
Guud ahaan, meelaynta tallaabooyin ka-hortagga is-waafajinta iyo ka-hortagga is-waafajinta ee xoogga leh ayaa la isku dari karaa si loo sameeyo ka-hortagga is-waafajinta kharash-ool ah.Culayska isha iswaafajinta leh ee leh awood weyn (sida foornooyinka soo noqnoqda, rogrogayaasha, iwm.), cabirada ka-hortagga is-waafajinta ayaa loo isticmaali karaa meelaynta tillaabooyinka lidka-iska-hortagga ah, si loo yareeyo is-waafajinta hadda la isku duray shabkada.Awood yar iyo culaysyo aan toos ahayn oo kala firdhiyey ayaa si isku mid ah loogu maamuli karaa baska dushiisa.Filterka firfircoon ee Hongyan APF waa la isticmaali karaa, iyo kontoroolka iswaafajinta sidoo kale waa la isticmaali karaa.
Foornada arc ee hooseysa waa foornada dhalaalka koronto ee isticmaalka tamarta sare leh oo leh sifooyinka foornada arc koronto ee iska caabin ah.Qodobka awoodda waxaa lagu go'aamiyaa qaansada iyo iska caabinta R ee foornada iyo qiimaha iska caabinta R iyo falcelinta X ee wareegga korontada (oo ay ku jiraan transformers, shabaqyada gaaban, giraannada aruurinta, daanka gacanta iyo electrodes).
cosφ=(r #+r)/resistance x qiimaha resistor r guud ahaan isma badalo marka foornada arc ee hoosaysa ay shaqaynayso, waxay ku xidhan yihiin naqshadaynta iyo rakibida shabakada gaaban iyo qaabka heerka korantada.Iska caabbinta R waxay la xiriirtaa xoojinta hadda ee qaybaha gaaban ee kor u kaca inta lagu jiro habka hawlgalka, isbeddelkuna maaha mid weyn, laakiin iska caabbinta R waa arrin muhiim ah oo lagu go'aaminayo awoodda foornada arc ee hoos u dhacaya inta lagu jiro habka hawlgalka. .
Maaddaama foornada arc-ku hoos jirta ay leedahay iska caabin daciif ah marka loo eego foornooyinka kale ee korontada ku shaqeeya, awooddeeda sidoo kale waa la dhimay si waafaqsan.Marka lagu daro heerka awoodda dabiiciga ah ee foornada miinada ee guud ee yar yar oo gaareysa kor u kaca 0.9, heerka awoodda dabiiciga ah ee foornada weyn ee miinada oo leh awood ka sarreysa 10000KVA ayaa dhammaan ka hooseeya 0.9, iyo awoodda weyn ee foornada miinada, hoos u dhigista awoodda. arrin.Tani waxay sabab u tahay culeyska weyn ee wax-soo-saarka is-beddelka foornada arc ee meel bannaan, dhererka shabakadda gaaban, iyo miisaanka qashinka ee la geliyo foornada, taas oo kordhisa falcelinta shabakada gaaban, taas oo yareyneysa awoodda awoodda. ee foornada arc ee quustay.
Si loo dhimo isticmaalka korantada, korna loogu qaado tayada nidaamka bixinta korontada, Xafiiska Korantada wuxuu dhigayaa in saamiga korontada ee shirkadda uu ahaado qiyaastii 0.9, haddii kale shirkadda korontada ayaa lagu ciqaabi doonaa ganaaxyo waaweyn.Intaa waxaa dheer, qodobka awoodda hooseeya ayaa sidoo kale hoos u dhigi doona korantada xariiqda soo socota ee foornada arc ee hooseysa, taas oo dhaawici doonta smelter carbide calcium.Sidaa darteed, wakhtigan xaadirka ah, foornooyinka arc hoostooda ee awoodda weyn ee gudaha iyo dibadda waxay u baahan yihiin in lagu rakibo qalabyada magdhowga tamarta falcelinta si loo hagaajiyo qodobka tamarta ee foornooyinka arc hoostooda.
Magdhow shaandhaynta danab hoose
1. Mabda'a
Magdhawga korantada-hooseeya waa qalab magdhow aan waxtar lahayn oo adeegsada tignoolajiyada casriga ah ee kantaroolka iyo tignoolajiyada shabakada-gaaban si ay ugu xidho awood-weyn, awood sare oo aad u hooseeya oo hadda ah dhinaca labaad ee foornada miinada.Qalabkani ma aha oo kaliya waxqabadka ugu fiican ee mabda'a magdhowga tamarta falcelinta, laakiin sidoo kale wuxuu ka dhigi karaa awoodda foornada miinada ee qiimaha sare leh, hoos u dhigista isticmaalka tamarta tamarta ee shabakada gaaban iyo dhinaca hoose, oo ka saarta saddexaad, shanaad iyo toddobaad harmonics.Isku dheellitir awoodda wax-soo-saarka saddexda waji si aad u kordhiso awoodda wax-soo-saarka transformer-ka.Diiradda xakameynta ayaa ah in la dhimo heerka aan dheeli tirnayn ee awoodda saddexda weji iyo in la gaaro awood siman oo saddex waji ah.Balaadhi dheriga isku dhejiska ah, xooga saar kulaylka, kordhi heerkulka foornada, oo dedeji falcelinta, si loo gaaro ujeedada hagaajinta tayada alaabta, yaraynta isticmaalka, iyo kordhinta wax soo saarka.
Farsamadani waxay khusaysaa tignoolajiyada qaan-gaarka ah ee soo jireenka ah ee magdhawga goobta dhinaca dambe ee tamarta hoose ee foornada miinada.Awoodda falceliska ah ee uu dhaliyo capacitor-ku waxa ay soo martaa xariiqda gaaban, qayb ka mid ah waxa ka nuugaya Transformer-ka foornada miinada ee nidaamka, qaybta kalena waxa ay magdhabisaa awoodda falcelinta ee transformerka foornada miinada, shabakad gaaban iyo electrodes.Luminta tamarta waxay kordhisaa gelinta tamarta firfircoon ee foornada.Isla mar ahaantaana, magdhow weji-kala-saar ah ayaa loo qaataa si loo sameeyo awoodda firfircoon ee saddex-waji ee electrodes ee foornada arc ee hooseysa si siman, si loo hagaajiyo awoodda awoodda, loo yareeyo dheelitir la'aanta awoodda saddex-waji, iyo hagaajinta wax soo saarka. index.
2. Codsiga magdhowga tamarta yar
Sanadihii la soo dhaafay, sababtoo ah horumarinta tartiib tartiib ah ee tiknoolajiyada magdhowga hooseeya, nidaamka naqshadeynta ayaa noqday mid aad u fiican, mugga ayaa si weyn loo dhimay.Soosaarayaasha foornada arc ee quusta ayaa sidoo kale ka bartay wax qabadkeeda hagaajinta faa'iidooyinka dhaqaale ee foornooyinka arc hoostooda.Qalabka magdhowga korantada yar ayaa si weyn loogu isticmaalay isbedbedelka foornada hoostiisa.
Xalka aad ka dooran karto:
qorshaha 1
Adeegso magdhowga shaandhada korantada-sare (xaalad tani waa magdhow guud, laakiin saamaynta dhabta ahi ma buuxinayso shuruudaha naqshadaynta).
Dhacdada 2
Dhinaca korantada yar, magdhowga shaandhada jajabyada saddex-waji ee firfircoon ayaa la qaatay.Ka dib marka qalabka shaandhada la geliyo shaqada, awoodda firfircoon ee saddex-waji ee elektiroonigga ah ee foornada arc ee hooseysa ayaa la simayaa, si loo hagaajiyo awoodda awoodda, loo yareeyo dheelitir la'aanta awoodda saddex-waji, iyo hagaajinta index-ka wax-soo-saarka.
