Dab-dhaliye Naaftada Naaftada ah waxa uu la mid yahay UPS

Maqaalkani waxa uu falanqeynayaa oo sharxayaa saamaynta ay ku leedahay shaandhada gelinta UPS koronto dhaliyaha si loo caddeeyo sababta dhibka keentay, kadibna xal loo helo.

1. Isku-dubbaridka u dhexeeya dab-dhaliye naaftada iyo UPS.

Soo-saareyaasha iyo isticmaaleyaasha nidaamyada korantada ee aan kala go'a lahayn waxay muddo dheer ogaadeen dhibaatooyinka isuduwidda ee u dhexeeya qalabka koronto-dhaliyaha iyo UPS, gaar ahaan is-waafajinta hadda jirta ee ay abuuraan dib-u-hagaajiyayaashu waxay ku abuurmaan nidaamyada korantada sida jaangooyooyinka korantada ee xirmooyinka koronto-dhaliyaha iyo isku-xirnaanta wareegyada UPS.Saamaynta xun ee tani waa mid aad u muuqata.Sidaa darteed, injineerada nidaamka UPS ayaa naqshadeeyay shaandhada gelinta waxayna ku dabaqeen UPS, iyagoo si guul leh u xakameynaya iswaafajinta hadda ee codsiga UPS.Shaandheeyayaashani waxay door muhiim ah ka ciyaaraan iswaafajinta UPS iyo qalabka wax dhaliya.

Ku dhawaad ​​dhammaan filtarrada wax soo gelinta waxay adeegsadaan capacitors iyo inductors si ay u nuugaan harmonics-ka hadda ugu xun ee wax gelinta UPS.Naqshadeynta shaandhada gelinta ayaa tixgalineysa boqolleyda ugu badnaan ee suurtagalka ah wadarta isku-dhafan ee ka dhex jira wareegga UPS iyo culeys buuxa.Faa'iidada kale ee filtarrada badankood waa in la hagaajiyo qodobka awoodda wax gelinta ee UPS-ka raran.Si kastaba ha ahaatee, cawaaqibka kale ee codsiga filtarka gelinta ayaa ah in la yareeyo waxtarka guud ee UPS.Inta badan filtarrada waxay cunaan qiyaastii 1% awoodda UPS.Naqshadeynta shaandhada gelinta ayaa had iyo jeer raadisa dheelitirnaanta u dhexeeya arrimo wanaagsan iyo kuwa aan fiicneyn.

Si loo hagaajiyo hufnaanta nidaamka UPS intii suurtagal ah, injineerada UPS ayaa dhowaan horumar ka sameeyay isticmaalka awoodda shaandhada gelinta.Hagaajinta waxtarka shaandhada waxay inta badan ku xidhan tahay adeegsiga tignoolajiyada IGBT (Insulated Gate Transistor) ee naqshadaynta UPS.Waxtarka sare ee rogaha IGBT ayaa horseeday in dib u habeyn lagu sameeyo UPS.Shaandheeyaha wax gelinta wuxuu nuugi karaa qaar ka mid ah harmonics-yada hadda jira isagoo nuugaya qayb yar oo ka mid ah awoodda firfircoon.Marka la soo koobo, saamiga qodobbada inductive-ka iyo arrimaha capacitive ee shaandhada waa la dhimay, mugga UPS waa la dhimay, waxtarkuna waa la hagaajiyay.Waxyaabaha ku jira goobta UPS waxay u muuqdaan in la xaliyay, laakiin waafaqid dhibaatada cusub ee koronto-dhaliyaha ayaa mar kale soo muuqday, bedelay dhibkii hore.

2. Dhibaatada dhawaaqa.

Dhibaatada kaabcitor-ka is-kicinta waxaa laga yaabaa inay ka sii darto ama dabooli karto xaaladaha kale ee korantada, sida resonance taxane ah.Marka qiimaha ohmic ee fal-celinta inductive ee koronto-dhaliyaha iyo qiimaha ohmic ee fal-celinta awoodda filtarka gelinta ay isku dhow yihiin midba midka kale, oo qiimaha iska caabbinta nidaamku uu yar yahay, oscillation ayaa dhacaya, oo danabku wuxuu ka badnaan karaa qiimaha la qiimeeyay ee awoodda. nidaamka.Nidaamka cusub ee UPS ee la nashqadeeyay ayaa asal ahaan 100% ka hor istaagi kara wax gelinta.UPS 500kVA waxa laga yaabaa inay lahaato awood 150kvar ah iyo awood u dhow eber.Shunt inductor-ka, chokes taxane ah, iyo beddeleyaasha go'doominta wax gelinta ayaa ah qaybaha caadiga ah ee UPS, qaybahanna dhammaantood waa firfircoon yihiin.Dhab ahaantii, iyaga iyo awoodda shaandhada si wada jir ah ayaa ka dhigaya UPS inay u dhaqmaan sidii karti guud ahaan, waxaana laga yaabaa inay horeba u jiraan qaar ka mid ah oscillations gudaha UPS.Marka lagu daro sifooyinka awoodda ee xadhkaha korantada ee ku xiran UPS, kakanaanta nidaamka oo dhan ayaa si weyn u kordhay, oo ka baxsan baaxadda falanqaynta injineerada caadiga ah.

3. Dab-dhaliye naafto ah oo la shubay.

Dab-dhaliyeyaasha naaftada waxay ku tiirsan yihiin nidaamiyaha danab si ay u xakameeyaan tamarta wax soo saarka.Xakamaynta danabku waxa uu ogaadaa danabka wax soo saarka saddexda weji wuxuuna isbarbar dhigayaa celceliska qiimahiisa iyo qiimaha danab ee loo baahan yahay.Maareeyuhu waxa uu tamar ka helayaa isha tamarta caawisa ee ku jirta koronto-dhaliyaha, sida caadiga ah koronto-dhaliye yar oo leh koronto-dhaliye weyn, oo u gudbiya awoodda DC gariiradda kicinta magnetic ee rotor-ga dhaliye.Xakamaynta gariiradda ayaa kor u kacda ama u dhacda si loo xakameeyo meeraha magnetic-ka ee wareegaaya gariiradda matoor stator , ama cabbirka xoogga korantada ee EMF.Qulqulka magnetic ee gariiradda stator ayaa go'aamisa tamarta wax soo saarka ee koronto dhaliyaha.

Iska caabbinta gudaha ee gariiradda stator ee set naaftada naaftada ah waxaa matala Z, oo ay ku jiraan qaybo wax soo saar iyo iska caabin ah;xoogga korantada ee koronto-dhaliyaha ay maamusho gariiradda kicinta rotor-ka waxaa matalaya E isha danabka AC.Iyadoo loo maleynayo in culeysku uu yahay mid soo jiidasho leh, hadda waxaan ka dhigayaa tamarta U ee saxda ah 90 ° xagasha korantada ee jaantuska vector.Haddii culeysku yahay mid iska caabin ah oo keliya, xididdada U iyo aniga ayaa isku beegmi doona ama noqon doonnaa weji.Dhab ahaantii, culaysyada badankoodu waxay u dhexeeyaan iska caabin kali ah iyo kaligii soo kicin.Hoos-u-dhaca danab ee ka dhashay socodka hadda socda ee gariiradda stator-ka waxa u taagan vector-ka I×Z.Dhab ahaantii waa wadarta laba qaybood oo danab yar, hoos u dhaca danab iska caabinta ee wajiga I iyo koronta inductor hoos 90 ° ka hor.Xaaladdan oo kale, waxay ku dhacdaa inay ku jirto marxaladda U. Sababtoo ah xoogga elektaroonigga ah waa inuu la mid yahay wadarta dhibcaha korantada ee caabbinta gudaha ee koronto-dhaliyaha, taas oo ah, wadarta guud ee vector E=U iyo I×ZXakameeyaha danabku wuxuu si wax ku ool ah u xakameyn karaa danabka U isagoo bedelaya E.

Hadda ka fiirso waxa ku dhacaya xaaladaha gudaha ee koronto-dhaliyaha marka culeys awood leh la isticmaalo beddelka culeyska kali ah.Waqtigan xaadirka ah waqtigan waa ka soo horjeeda culeyska soo kicinta.Hadda I hadda waxay hogaamisaa xuubka danabka U, iyo hoos u dhaca danab iska caabbinta gudaha I×Z sidoo kale waa waji ka soo horjeeda.Markaa wadarta guud ee U iyo I×Z way ka yar tahay U.

Maadaama isla xoogga korantada E ee culeyska inductive uu soo saaro koronto dhaliye sare U ee culeyska awoodda, nidaamiyaha danabku waa inuu si weyn u yareeyaa wareegga magnetic.Run ahaantii, maamulaha danabku waxa laga yaabaa in aanu haysan baaxad ku filan oo uu si buuxda u xakameeyo tamarta wax soo saarka.Rotors ee dhammaan koronto-dhaliyeyaasha ayaa si joogto ah ugu faraxsan hal jiha waxayna ka kooban yihiin goob birlabeed joogto ah.Xitaa haddii korantadu si buuxda u xiran tahay, rotor-ku wuxuu weli leeyahay dhul birlab ah oo ku filan si uu u dallaco culeyska awoodda oo uu dhaliyo koronto.Dhacdadan waxa loo yaqaan "is-kicinta".Natiijooyinka is kicinta ayaa ah koronto-dhaafka ama xiritaanka xakameynta korantada, iyo nidaamka kormeerka koronto-dhaliyuhu wuxuu u arkaa inay tahay guul-darreysa maamulaha tamarta (ie, "luminta kicinta").Mid ka mid ah xaaladahan ayaa sababi doona in koronto-dhaliyaha uu istaago.Culayska ku xiran wax-soo-saarka koronto-dhaliye wuxuu noqon karaa mid madax-bannaan ama isbar-bar socda, iyadoo ku xiran waqtiga iyo goobta golaha beddelka tooska ah.Codsiyada qaarkood, nidaamka UPS waa culeyska ugu horreeya ee ku xiran koronto-dhaliye inta lagu jiro cillad koronto.Xaaladaha kale, UPS iyo culeyska farsamada ayaa isku mar ku xiran.Culayska makaanikku wuxuu badanaa leeyahay xiriiriyaha bilawga ah, waxayna qaadataa wakhti go'an in dib loo soo celiyo ka dib markii korontadu xumaato.Waxaa jira dib u dhac lagu samaynayo magdhowga culeyska mootada soo kicinta ee capacitor galinta UPS.UPS lafteedu waxay leedahay wakhti loo yaqaan "soft start", kaas oo ka beddelaya culayska batteriga una beddelaya koronto-dhaliye si uu u kordhiyo cunsurkiisa awoodda.Si kastaba ha ahaatee, filtarrada soo gelida UPS kama qaybqaataan nidaamka bilawga jilicsan.Waxay ku xidhan yihiin dhamaadka gelinta UPS oo qayb ka ah UPS.Sidaa darteed, xaaladaha qaarkood, culeyska ugu weyn ee marka hore ku xiran wax soo saarka koronto-dhaliyaha inta lagu jiro korontadu waa filtarka gelinta ee UPS.Aad bay u awood badan yihiin (mararka qaarkoodna waa awood awood leh).

Xalka dhibaatadan ayaa iska cad in la isticmaalo sixitaanka qodobka awoodda.Waxaa jira siyaabo badan oo tan lagu gaaro, qiyaas ahaan sida soo socota:

1. Ku rakib armaajo beddelka tooska ah si aad uga dhigto culeyska mootada ku xiran UPS ka hor.Qaar ka mid ah armaajooyinka beddelka ayaa laga yaabaa inay awoodi waayaan inay hirgeliyaan habkan.Intaa waxaa dheer, inta lagu jiro dayactirka, injineerada dhirta ayaa laga yaabaa inay u baahdaan inay si gooni ah u saxaan UPS iyo koronto-dhaliyeyaasha.

2. Ku dar falcelinta falcelinta joogtada ah si aad u magdhabiso culeyska awooda, badiyaa adoo isticmaalaya fal-celiyaha dabaylaya ee barbar socda, oo ku xidhan EG ama sabuuradda isbarbar yaalka wax soo saarka.Tani aad bay u fududahay in la gaaro, kharashkuna waa yar yahay.Laakin dhib malaha culeyska sare ama culeyska hooseeya, reactor-ku wuxuu had iyo jeer nuugaa hadda wuxuuna saameeyaa qodobka awoodda culeyska.Oo iyada oo aan loo eegin tirada UPS, tirada reactors had iyo jeer waa go'an.

3. Ku rakib reaktoore inductive UPS kasta si aad u magdhabiso falcelinta awooda ee UPS.Xaaladda culeyska hooseeya, xiriiriyaha (ikhtiyaarka) ayaa xakameynaya gelinta reactor.Habkan reactor-ka ayaa ah mid sax ah, laakiin tiradu waa weyn tahay, kharashka rakibidda iyo xakamaynta ayaa sarreeya.

4. Ku rakib qalabeeyaha hortiisa capacitor filtarka oo ka saar marka culeysku yar yahay.Maadaama wakhtiga xiriiriyaha uu yahay mid sax ah oo xakameyntu ay aad u adag tahay, kaliya waxaa lagu rakibi karaa warshadda.

Habka ugu fiican wuxuu ku xiran yahay xaaladda goobta iyo waxqabadka qalabka.
