Izixazululo emaphutheni ajwayelekile ezikrinini zokuthinta ze-Nokia
1. Imininingwane yephutha lesigaba esisodwa noma iphutha lesigaba esiningi liboniswa ngokuthi "inverter u" noma "inver v noma w". Isizathu ukuthi i-inverter eyodwa noma yesigaba esiningi ihluleka. Uma inani eliphakeme lamanje le-switchch tube yimi> 3INRMS, i-INRMS yi-IGBT. Lesi simo sizokwenzeka uma kunenkinga nge-inverter yamanje, noma kunokuthile okungahambi kahle ngokuhlinzekwa kwamandla okusuluzayo kwesigaba esisodwa sesango. Ngemuva kwalolu hlobo lwephutha kwenzeka, kungadala umjikelezo omfushane endaweni yokuphuma kwesiguquli semvamisa, noma kungadala futhi ukuthi imoto idlidlize kakhulu izilungiselelo ezingalungile. Kunezimo ezimbili ngokuvamile ngesikhathi sokulungiswa:
. Igagasi lokushintshashintsha liyigagasi le-sine, futhi igagasi lenkampani yenethiwekhi liyi-bipolar isperes unxantathu wave. Iphuzu lokuhlangana lokuhamba ngegagasi lokushintshanisa kanye ne-carrierve wave inquma uchungechunge lwe-pulse lwe-inverter bridrold akepput Isigaba se-Voltage. Iphaneli yokulawula umnyango ibonwa nge-IC ehlanganisiwe ye-IC (Asic), efaka i-generator yemvamisa yedijithali enesinqumo esifinyelela ku-0.001hz kanye nemvamisa ephezulu ye-500hz kanye ne-pulse Width Modulator ekhiqiza i-wave yesihla sesibili uhlelo. Le modulator isebenza ngokusobala ku-asynchronous imvamisa ye-pulse ye-8KHZ. I-voltage pulses ikhiqiza ngokushintshana ngokushintsha futhi ivale amadivayisi wamandla amabili ekhasini elifanayo lebhuloho. Uma leli bhodi lesekethe lihluleka, ngeke likwazi ukukhiqiza ama-voltage pulses ngokujwayelekile, futhi iBhodi lidinga ukushintshwa futhi lilungiswe.
2 I-Inverter yedivaysi yehluleka idivaysi ye-inverter esetshenziswa ku-Nokia Ingterers iyisango elifakiwe i-Bipolar Transistor - Igbt. Izici zalo zokulawula zingukuvimbela okuphezulu okuphezulu kanye nesango elincane kakhulu elikhona, ngakho-ke amandla okushayela lincane futhi angasebenza kuphela esimweni sokushintsha. Ayikwazi ukusebenza ngesimo esikhulisiwe. Imvamisa yayo yokushintsha ingafinyelela phezulu kakhulu, kepha ukusebenza kwawo kwama-antistatic ampofu. Ukuthi ingxenye ye-IGBT inephutha ingalinganiswa nge-ohmmeter. Izinyathelo ezithile zinjengokulandelayo:
● Nqamula ukunikezwa kwamandla kwesiguquli semvamisa;
● Nqamula imoto elawulwayo;
● Sebenzisa i-ohmmeter ukukala ukungcola kwama-terminal okuxhumeka okuxhumeka kanye nama-dc terminals a no d (bheka isithombe esinamathiselwe). Kala isivivinyo ngasinye kabili ngokushintsha ubukhosi be-ohmmeter. Uma i-IGBT yesiguquli se-Frequency iqinile, kufanele kube: kusuka ku-U2 kuye ku-a Kusuka ku-U2 kuye ku-D, kungukumelana okuphezulu; Ngaphandle kwalokho, ukumelana okuphansi. Okufanayo kuhamba ezinye izigaba. Lapho i-IGBT inqanyulwa, inenani eliphakeme lokumelana zombili izikhathi, futhi uma lizungeza isikhashana, linenani eliphansi lokumelana.

I-3 yokusebenzisa amandla okusebenzisa amandla okusetshenziswa komlayezo wephutha ikhonjiswa ngokuthi "ukumelana okugcwele", okusho ukuthi amandla okusebenzisa amandla agcwele kakhulu. Kunezizathu ezintathu zalokhu: I-voltage yokuvuselela kabusha i-voltage iphezulu kakhulu, amandla okubhula aphezulu kakhulu noma isikhathi sokubopha sifushane kakhulu. Umphikisi wokusebenzisa amandla yingxenye eyengeziwe. Njengoba umthwalo wezindwangu wezindwangu kanye ne-chemical fiber ngumthwalo omkhulu we-inertia, ishubhu eliphakeme lamandla namandla okusebenzisa amandla axhumeke ngokufana nengxenye ye-DC yesiguquli se-Frequency. Umsebenzi wayo oyinhloko ukuxhumanisa i-Power Supply ngamandla anciphisa amandla okuvela kulayini we-DA lapho uvula, uvale noma ulayisha. Kepha lapho i-braking yamanje idlula isilinganiso, umsebenzi uzophazamiseka. Kunezimo ezijwayelekile:
(1) Ukwehluleka ukusetshenziswa kwamandla kwamandla. Esiguqulweni sangempela semvamisa, i-pulse Resistor ingu-7.5ω / 30kw. Ngemuva kokusebenzisa i-inverter iminyaka eminingana, ngenxa yokuqala okujwayelekile kanye nokuma kwe-inverter, ukumelana nokuvutha okuvuthayo futhi ukumelana kwalo kwehle. Kodwa-ke, ama-inverters e-Nokia anezimfuneko eziqinile ngenani lazo lokumelana, okudingeka ukuba libe likhulu kuno noma lilingane no-7.5ω. Ngakho-ke, yize ukumelana komphikisi wale mandla wale nhloli cishe ku-7.1 ω, leli phutha elingenhla lizokwenzeka futhi ngeke likwazi ukuqala ngokujwayelekile. Kamuva, ngashintshela ku-aprilor yamandla aphezulu ngenani lokumelana elingaba yi-8ω ngaphambi kokuthi ngilivule.
(2) Ukwehluleka kwe-IGBT. Kunephutha engxenyeni ye-IGBT ye-Inverter, ebangela impendulo eyeqile kabusha yamanje futhi ibangela ukwehluleka okulayishwa ngokweqile komphikisi wokusebenzisa amandla.
4 Ukushisa kwesiguquli semvamisa kubangelwa yithuluzi le-inverter. Idivayisi ye-Inverter ibuye ibe yingxenye ebaluleke kakhulu futhi entekenteke kakhulu yesiguquli semvamisa, ngakho-ke inzwa yokushisa (NTC) esetshenziselwa ukukala izinga lokushisa nayo ifakiwe engxenyeni engenhla yedivayisi ye-inverter. Lapho amazinga okushisa edlula ama-60 ℃, i-frequency converter izokwazi uku-alamu ngokudluliswa kwesiginali; Lapho ifinyelela kuma-70 ℃, i-Frequency Converter izoma ngokuzenzakalelayo ukuze ivikeleke. Ukushisa ngokweqile kuvame ukubangelwa yizimo ezinhlanu:
(1) Ukushisa okukhona kuphakeme. Amanye ama-workshops anamazinga okushisa aphezulu akhona futhi akude kakhulu negumbi lokulawula. Ukuze usindise amakhebuli bese wenza lula ukusebenza kwesayithi, i-inverter kufanele ifakwe esizeni esikhundleni somhlangano. Ngalesi sikhathi, ungangeza i-duct yomoya ebandayo engxenyeni yokungena emoyeni yesiguquli semvamisa ukusiza ukuqeda ukushisa.
(2) Ukwehluleka kwabalandeli. I-fan ephelele ye-frequency converter iyimoto engu-24v DC. Uma i-fan ethwala ilimele noma ikhoyili iyashiswa futhi fan ayiguquki, izokwenza isiguquli semvamisa ukuze sigcwale ngokweqile.
(3) Ukushisa ukushisa kungcolile kakhulu. Kukhona idivaysi yokuhlanza ukushisa kwe-aluminium ngemuva kwe-inverter yesiguquli semvamisa. Ngemuva kokugijima isikhathi eside, ingaphandle lizombozwa ngothuli ngenxa kagesi oluqinile, lithinta kakhulu umphumela we-radiator. Ngakho-ke, kuyadingeka ukuhlanza futhi uhlanze njalo.
(4) ukulayisha ngokweqile. Umthwalo ophathwe ngumguquli wemvamisa ugcwele isikhathi eside, okwenza ukushisa. Ngalesi sikhathi, hlola ugesi
