Izixazululo zamaphutha ajwayelekile ezikrinini zokuthinta ze-Siemens
Izixazululo zamaphutha ajwayelekile ezikrinini zokuthinta ze-Siemens
1. Ulwazi lwephutha lwephutha lesigaba esisodwa noma lezigaba eziningi luboniswa njengokuthi “inveter u” noma “inveter v noma w”. Isizathu siwukuthi i-inverter yesigaba esisodwa noma yesigaba esiningi iyahluleka. Uma inani eliphezulu leshubhu lokushintsha lingu-i>3inrms, i-inrms ithi igbt. Lesi simo sizokwenzeka uma kunenkinga ngesilinganiso samanje se-inverter, noma kukhona okungalungile ngokunikezwa kwamandla asizayo kwesigaba esisodwa sesango le-inverter. Ngemuva kokwenzeka kwalolu hlobo lwephutha, kungabangela ukujikeleza okufushane ekugcineni kokuphumayo kwesiguquli sefrikhwensi, noma kungabangela ukuthi injini idlidlize kakhulu ngenxa yezilungiselelo zesilawuli ezingalungile. Ngokuvamile kunezimo ezimbili ngesikhathi sokulungiswa:
(1) I-Trigger board failure Lapho i-Siemens inverter yenza ukuguqulwa kobubanzi be-pulse, umjikelezo womsebenzi wochungechunge lwe-pulse uhlelwa ngokuvumelana nomthetho we-sinusoidal. Igagasi lokumodulation liyigagasi elinesine, futhi igagasi elithwalayo liyigagasi elingunxantathu we-bipolar isosceles. Iphoyinti lokuphambana kwegagasi lokumodulation kanye negagasi lesithwali linquma uchungechunge lwe-pulse ye-voltage yesigaba sokuphuma kwebhuloho le-inverter. Iphaneli yokulawula umnyango yenziwa nge-IC (ASIC) enkulu edidiyelwe, ehlanganisa ijeneretha yefrikhwensi yedijithali enesixazululo esingafika ku-0.001hz kanye nemvamisa enkulu engu-500hz kanye ne-pulse wide module ekhiqiza i-sine wave yezigaba ezintathu. uhlelo. Le Modulator isebenza ngokuvumelanayo ngemvamisa ye-pulse engashintshi engu-8khz. Ama-voltage pulses ewakhiqizayo avule futhi avale amadivaysi amabili okushintsha amandla engalweni efanayo yebhuloho. Uma leli bhodi lesifunda lihluleka, ngeke likwazi ukukhiqiza ama-voltage pulses ngokujwayelekile, futhi ibhodi lidinga ukushintshwa futhi lilungiswe.
2 Ukwehluleka kwedivayisi yokuguqula Umshini oguquguqukayo osetshenziswa kuma-inverter we-Siemens iyisango elivaliwe elishintshashintshayo le-bipolar - igbt. Izici zayo zokulawula ziyi-impedance ephezulu yokufaka kanye nesango elincane kakhulu lamanje, ngakho amandla okushayela mancane futhi angasebenza kuphela esimweni sokushintsha. Ayikwazi ukusebenza esimweni sokukhuliswa. Imvamisa yayo yokushintsha ingafinyelela phezulu kakhulu, kepha ukusebenza kwayo kwe-antistatic kubi. Ukuthi ingxenye ye-igbt inephutha yini ingalinganiswa nge-ohmmeter. Izinyathelo eziqondile zimi kanje:
● Nqamula ukunikezwa kwamandla kwesiguquli sefrikhwensi;
● Nqamula injini elawulwayo;
●Sebenzisa i-ohmmeter ukukala ukuthintana kwetheminali ephumayo kanye namatheminali oxhumano lwe-DC a no-d (bheka isithombe esinamathiselwe). Linganisa ukuhlolwa ngakunye kabili ngokushintsha i-polarity ye-ohmmeter. Uma i-igbt ye-converter ye-frequency iphelele, kufanele ibe: kusuka ku-u2 kuya ku-a ukumelana okuphansi, ngaphandle kwalokho, ukumelana okuphezulu; kusuka ku-u2 kuya ku-d, kungukumelana okuphezulu; uma kungenjalo, ukumelana okuphansi. Kungokufanayo nakwezinye izigaba. Uma i-igbt inqanyuliwe, inenani eliphakeme lokumelana nezikhathi zombili, futhi uma ine-circuited emfushane, inenani eliphansi lokumelana.
3 Ukwehluleka ukumelana nokusetshenziswa kwamandla Umlayezo oyiphutha ukhonjiswa “njenge-pulsed resistor”, okusho ukuthi isivimbeli sokusebenzisa amandla sigcwele ngokweqile. Kunezizathu ezintathu zalokhu: i-voltage ye-braking evuselelayo iphezulu kakhulu, amandla okubhuleka aphakeme kakhulu noma isikhathi sokubhuleka sifushane kakhulu. I-resistor yokusetshenziswa kwamandla iyingxenye eyengeziwe. Njengoba umthwalo wemishini yendwangu kanye ne-chemical fiber ungumthwalo omkhulu we-inertia, ishubhu yokushintsha amandla aphezulu kanye nokumelana nokusetshenziswa kwamandla kuxhunywe ngokuhambisana nengxenye ye-DC yesiguquli semvamisa kuzintambo ze-DA. Umsebenzi wayo oyinhloko ukuxhuma amandla kagesi Beka umkhawulo ku-overvoltage ye-da uma ukhanyisa, ucisha noma ulayisha. Kodwa lapho i-braking current idlula isilinganiso, ukusebenza kuzophazamiseka. Ngokuvamile kunezimo ezimbili:
(1) Ukwehluleka kokumelana nokusetshenziswa kwamandla. Ku-converter yefrikhwensi yangempela, i-pulse resistor ingu-7.5ω/30kw. Ngemuva kokusebenzisa i-inverter iminyaka eminingana, ngenxa yokuqala kanye nokuma kwe-inverter, i-resistor iyashisa futhi ukumelana kwayo kwehla. Kodwa-ke, ama-inverters e-Siemens anezidingo eziqinile kunani layo lokumelana, okudingeka ukuthi libe likhulu noma lilingane no-7.5ω. Ngakho-ke, nakuba ukumelana kwe-resistor yokusetshenziswa kwamandla kwalesi inverter cishe ku-7.1ω, iphutha elingenhla lizokwenzeka futhi ngeke likwazi ukuqala ngokujwayelekile. Kamuva, ngashintshela kusiphikisa samandla aphezulu esinenani lokumelana elicishe libe ngu-8ω ngaphambi kokuthi ngikwazi ukusivula.
(2) ukwehluleka kwe-igbt. Kukhona iphutha engxenyeni ye-igbt ye-inverter, edala impendulo evuselelayo eyeqile futhi ibangele ukwehluleka kokulayisha ngokweqile kwe-resistor yokusetshenziswa kwamandla.
4. Iphutha lokushisa ngokweqile Umlayezo wephutha uboniswa “njengezinga lokushisa elingaphezu kwamandla” ngoba izinga lokushisa lokukhipha ukushisa kwe-inverter liphezulu kakhulu. Ukushisisa kwesiguquli sefrikhwensi kubangelwa ikakhulukazi idivayisi ye-inverter. Idivayisi ye-inverter nayo iyingxenye ebaluleke kakhulu futhi entekenteke yesiguquli se-frequency, ngakho-ke inzwa yezinga lokushisa (ntc) esetshenziselwa ukukala izinga lokushisa nayo ifakwe engxenyeni engenhla yedivayisi ye-inverter. Uma izinga lokushisa lidlula u-60 ℃, isiguquli sefrikhwensi sizokwenza i-alamu kusengaphambili ngokudluliswa kwesignali; uma ifinyelela ku-70℃, isiguquli semvamisa sizoma ngokuzenzakalela ukuze sizivikele. Ukushisa ngokweqile ngokuvamile kubangelwa izimo ezinhlanu:
(1) Izinga lokushisa lendawo liphezulu. Amanye ama-workshops anamazinga okushisa aphezulu aphezulu futhi akude kakhulu negumbi lokulawula. Ukuze ulondoloze izintambo futhi wenze lula ukusebenza endaweni, i-inverter kufanele ifakwe esizeni endaweni yokusebenzela. Ngalesi sikhathi, ungakwazi ukwengeza ipayipi lomoya obandayo endaweni yokungenisa umoya yesiguquli sefrikhwensi ukuze usize ukuqeda ukushisa.
(2) Ukwehluleka kwabalandeli. I-fan exhaust ye-frequency converter iyinjini engu-24v DC. Uma i-fan bear yonakalisiwe noma ikhoyili ishile futhi ifeni ingazungezi, lokho kuzokwenza ukuthi isiguquli sefrikhwensi sishise kakhulu.
(3) Isitsha sokushisa singcole kakhulu. Kukhona idivayisi yokukhipha ukushisa kwe-aluminium fin ngemuva kwe-inverter yesiguquli sefrikhwensi. Ngemva kokugijima isikhathi eside, ingaphandle izombozwa uthuli ngenxa kagesi omile, okuthinta kakhulu umphumela we-radiator. Ngakho-ke, kuyadingeka ukuhlanza nokuhlanza njalo.
(4) Layisha kakhulu. Umthwalo othwelwe yi-converter frequency ulayishwa ngokweqile isikhathi eside, okubangela ukushisa. Ngalesi sikhathi, hlola ugesi
