Foornada soo noqnoqda ee dhexdhexaadka ah waa qalab koronto u beddela 50Hz AC quwad dhexdhexaad ah (300Hz ilaa 100Hz), ka dibna u beddela awoodda saddexda weji ee AC oo u beddesha awoodda DC, ka dibna awoodda DC u beddesha soo noqnoqoshada dhexdhexaadka ah ee hadda jira, kaas oo ku qulqula capacitors iyo gariiradda induction.Samee khadadka xoogga cufnaanta sare leh, gooya walxaha birta ah ee ku jira gariiradda induction, adeegso mabda'a kicinta korantada si aad u dhaliso qulqul weyn oo birta ah, kuleylka walxaha birta, oo dhalaalin
Foornada induction soo noqnoqda ee inta jeer ee dhexdhexaadka ah waa culeys nidaamsan.Inta lagu jiro habka hawlgalka, qulqulka harmonic ayaa lagu soo bandhigaa shabkada korantada, taasoo keenta danab hadda garaaca garaaca sifada korantada, taasoo keenta isbedbeddelka korantada ee shabkada korantada, oo saameeya tayada nidaamka bixinta korantada iyo badbaadada hawlgalka qalabka .Maaddaama sahayda korantada ganacsiga ee foornada soo noqnoqda dhexdhexaadka ah ay noqoto soo noqnoqoshada dhexdhexaadka ah iyada oo loo marayo beddelaha soo noqnoqda ee dib u habeynta, korantadu waxay dhalin doontaa tiro badan oo waxyeello ah oo hawo-sare ah inta lagu jiro hawlgalka, taas oo ah mid ka mid ah ilaha is-waafajinta ee ugu weyn culeyska korantada.
Shan sifo oo foornada inta jeer ee dhexdhexaadka ah
1. Lacag kaydso
Kuleyl degdeg ah, wax soo saar sare, carburization oksaydhka hawada oo yaraada, badbaadinta alaabta ceeriin iyo kharashyada, iyo sii dheeraynta nolosha adeegga qalabka wax-soo-saarka.
Sababtoo ah mabda'a foornada induction soo noqnoqda ee dhexdhexaadka ah waa korantada, kulaylka ay dhaliso foornada soo noqnoqda ee dhexdhexaadka ah waxaa dhaliya birta lafteeda.Shaqaalaha caadiga ah waxay ku fulin karaan shaqada joogtada ah ee hawsha been abuurka ah toban daqiiqo gudahood ka dib marka la isticmaalo foornada soo noqnoqda ee dhexdhexaadka ah, iyada oo aan loo baahnayn soo saarista foornada.Shaqaaluhu waxay hore u bilaabeen shaqada foornada iyo daminta dabka.Sababtoo ah habkan kuleylku si dhakhso ah ayuu u kululeeyaa oo uu leeyahay oksaydhism yar, ablation-ka oksijiinta ee celceliska dhexdhexaadka ah ee kuleyliyeyaasha birta ah waa 0.5% oo keliya, oksijiinta kuleylka foornada gaaska waa 2%, foornada dhuxusha ceeriin ayaa ka sarreysa 3%.Habka kululaynta inta jeer ee dhexdhexaadka ah waxay badbaadisaa alaabta ceeriin, marka la barbar dhigo foornooyinka dhuxusha ceeriin, hal tan oo bir ah oo shub ah ayaa badbaadiya 20-50KG taarikada birta ah ee ka yar.Heerka isticmaalka alaabta ceeriin wuxuu gaari karaa 95%.Sababtoo ah kuleylku waa labis iyo farqiga heerkulka u dhexeeya dusha sare waa mid yar, nolosha adeegga ee dhinta been-abuurka ah ayaa si weyn u kordhay inta lagu jiro been-abuurka.Qalafsanaanta been-abuurka ahi way ka hoosaysaa 50um, tignoolajiyada farsamayntuna waa tamar-badbaadin.Kuleyliyaha inta jeer ee dhexdhexaadka ah wuxuu badbaadin karaa tamarta 31.5% -54.3% marka la barbar dhigo kuleylka saliidda, iyo kuleylka gaaska tamarta badbaadinta 5% -40%.Tayada kuleylka ayaa wanaagsan, heerka qashinka waxaa lagu dhimi karaa 1.5%, heerka wax soo saarka waxaa lagu kordhin karaa 10% -30%, iyo nolosha adeegga qalabka wax-soo-saarka ayaa lagu kordhin karaa 10% -15%.
2. Qodobbada ilaalinta deegaanka
Bey'ad xafiis oo heer sare ah, hagaajinta jawiga xafiiska ee shaqaalaha iyo astaanta shirkadda, wasakhowga eber, badbaadinta tamarta.
Marka la barbar dhigo shooladaha dhuxusha, foornooyinka kuleyliyaha induction laguma qiiqi karo shooladaha dhuxusha ee kulaylka aadka u daran, kaas oo buuxin kara shuruucda Hay'adda Ilaalinta Deegaanka.Intaa waxaa dheer, waxay qaabeyn kartaa sawirka sumadda dibadda ee shirkadda waxayna abuurtaa isbeddelka horumarinta warshadaha ee warshadaha wax soo saarka.Kuleylinta Induction waa kuleylinta tamarta foornada korontada laga bilaabo heerkulka qolka ilaa 100 ° C, isticmaalka korontada ayaa ka yar 30 ° C, isticmaalka foornada ayaa ka yar 30 ° C.Habka qaybinta isticmaalka been abuurka ah
3. Miraha kululaynta
Kuleylinta isku midka ah, farqiga heerkulka yar ee u dhexeeya xudunta iyo dusha sare, saxnaanta heerkulka sare
Kuleyliyaha induction wuxuu abuuraa kulayl birta lafteeda, markaa kuleyliyuhu waa xitaa farqiga heerkulka u dhexeeya xudunta iyo dusha sare waa yar yahay.Codsiga nidaamka xakamaynta heerkulka ayaa si sax ah u xakameyn kara heerkulka, hagaajinta tayada alaabta iyo heerka gudbinta.
4. Qiime
Foornada inta jeer ee dhexdhexaadka ah ayaa si dhakhso ah u kululeysa, foornada dhalaalaysa birta waxay isticmaashaa tamarta korantada ee aan ka badnayn 500 darajo, dhalaalkuna waa mid dhamaystiran oo degdeg ah.
5. Waxqabadka badbaadada
Nidaamka kormeerka fog ee foornada korontada ee dhexdhexaadka ah ayaa la doortay, taas oo ku habboon jawiga wax soo saarka warshadaha.Awood xoog leh oo ka-hortagga faragelinta iyo arrin badbaado oo sarreeya.Ma jiro wax silig ah oo ku xidhan aaladda hawlgalka iyo aaladda la kontoroolo, taas oo ah, kontoroolka fogfog.Dhammaan hawlgallada adag, riix furayaasha kontoroolka fog fog fog.Ka dib markii la helo tilmaamaha, foornada koronto ee inta jeer ee dhexdhexaadka ah waxay dhamaystiri kartaa hawlgallada u dhigma tallaabo tallaabo iyadoo loo eegayo habka wanaagsan.Sababtoo ah foornada korantada waa qalab koronto oo aad u sarreeya, ma aha oo kaliya ammaan, laakiin sidoo kale waxay ka fogaan kartaa waxyeellada foornada korontada sababtoo ah argagaxa ay sababaan khaladaadka shaqada.
Waa maxay sababta foornada inta jeer ee dhexdhexaadka ah ay dhaliso harmonics
Harmonics-ku waxay si dhab ah u khatar gelinaysaa hawlgalka badbaadada leh ee xadhkaha korantada.Tusaale ahaan, hadda isku-dhafan waxay keenaysaa khasaare dheeraad ah oo birta vortex-ka sare ah ee Transformer-ka, taas oo keeni doonta in Transformer-ku uu kululaado, hoos u dhigo mugga wax-soo-saarka transformer-ka, kordhinta qaylada transformer-ka, khatar weynna u gelin doonta nolosha adeegga beddelka .Saamaynta isku dhejinta ee qulqulka iswaafajinta waxay yaraynaysaa is-goysyada joogtada ah ee kirishbooyada waxayna kordhisaa luminta khadka.Korantada Harmonic waxay saamaysaa shaqada caadiga ah ee qalabka kale ee korantada ee shabkada, taasoo keenta khaladaadka shaqada ee qalabka xakamaynta tooska ah iyo xaqiijinta cabbirka aan saxda ahayn.Voltage harmonic iyo hadda waxay saameeyaan hawlgalka caadiga ah ee qalabka isgaarsiinta durugsan;korantada ku meel gaadhka ah iyo korantada ku meel gaadhka ah ee ay sababto is-waafajinta waxay dhaawacdaa lakabka dahaadhka ee mishiinada iyo qalabka, taas oo keentay ciladad wareegyada gaaban ee saddexda weji ah iyo waxyeelo soo gaadhay transformers;danab iswada leh iyo Qadarka hadda socda waxa uu sababi doonaa dhawaaq taxane ah oo qayb ah iyo dhawaaq isbarbar socda shabkada korantada dadweynaha, taas oo keenta shilal waaweyn.Geedi socodka oo dhan ee sahayda inverter-ka, sahayda ugu horeysa ee DC ee xasiloon waa sahayda korantada ee mowjad labajibbaaran, taas oo u dhiganta ururinta hirarka sinaha oo leh qulqulo badan oo garaaca wadnaha ah.Inkasta oo wareegga marxaladda ka dambeeya uu u baahan yahay shaandheyn, harmonics si buuxda looma sifeyn karo, taas oo ah sababta harmonics.
Awoodda isku-dhafan ee foornada inta jeer ee dhexdhexaadka ah
Awoodda wax-soo-saarka foornada soo-celinta soo noqnoqda ee dhexdhexaadka ah way ka duwan tahay, is-waafajinta qaraabada ah ayaa sidoo kale ka duwan:
1. Awoodda dabiiciga ah ee foornada soo noqnoqda ee dhexdhexaadka ah ee awoodda sare waxay u dhaxaysaa 0.8 iyo 0.85, baahida tamarta falcelinta waa weyn tahay, nuxurka is-waafajinta ayaa sarreeya.
2. Awoodda dabiiciga ah ee foornada soo noqnoqda ee tamarta hoose waa inta u dhaxaysa 0.88 iyo 0.92, iyo baahida tamarta falcelinta waa yar tahay, laakiin nuxurka is-waafajinta waa mid aad u sarreeya.
3. Harmonics dhinaca saafiga ah ee foornada inta jeer ee dhexdhexaadka ah waxay u badan tahay 5th, 7th iyo 11th.
Habka xakamaynta harmonic ee foornada inta jeer ee dhexdhexaadka ah
filtarrada hal-habboon ee 5, 7, 11 iyo 13 jeer ayaa la naqshadeeyay.Kahor magdhowga shaandhaynta, qodobka awooda ee isku xirka foornada soo noqnoqda ee dhexdhexaadka ah ee macaamilka waa 0.91.Ka dib marka la geliyo qalabka magdhawga shaandhada, magdhowga ugu badan waa 0.98 capacitive.Ka dib marka la geliyo qalabka magdhawga shaandhada, wadarta guud ee heerka qallooca korantada ee shaqaynaysa (wadarta qiimaha qallooca iswaafajinta) waa 2.02%.Marka loo eego heerka tayada korantada GB/GB/T 14549-1993, qiimaha korantada shaqada ee harmonic (10KV) wuxuu ka hooseeyaa 4.0%.Ka dib marka la sameeyo filtarrada 5th, 7th, 11th iyo 13th harmonic currents, heerka filtarku waa 82∽84%, kaas oo ka sarreeya qiimaha kantaroolka ee heerka warshadaha shirkadeena.Saamaynta shaandhada magdhowgu waa wanaagsan tahay.
