Uchungechunge lwe-TYPKK oluguquguqukayo lwejubane eliphezulu lamandla kagesi asebenza kahle kakhulu ezigabeni ezintathu ezihlala unomphela uzibuthe we-synchronous motor (6kV H355-1000)
Incazelo yomkhiqizo
Ubukhulu bokufakwa kwamamotho kazibuthe unomphela buyafana nochungechunge oluyisisekelo lwe-TYKK.Uchungechunge oluyisisekelo yi-TYPKK air-air cooled, isigaba sokuvikela ukungena kwe-IP55, ukufakwa kwesigaba F, umsebenzi wokusebenza we-S1.Amanye amazinga okuvikela kanye nezindlela zokupholisa ziyatholakala ngokwezidingo zamakhasimende.
Lolu chungechunge lutholakala nge-voltage elinganiselwe ye-6 kV, enikwa amandla yi-converter frequency, ngaphansi kwe-frequency elinganiselwe, ukusebenza kwe-torque engaguquki.
Lolu chungechunge lusebenza kahle kakhulu (injini ye-IE5) kanye nobubanzi bokusebenza kwezomnotho olubanzi kunama-asynchronous motors anosayizi ofanayo ebangeni lokulayisha lika-25% kuya ku-120% futhi linokonga amandla okubalulekile.
Umphumela uba ukonga amandla okubalulekile.Ukukhuphuka kwezinga lokushisa kwe-motor kuphansi, i-40-60K ngaphansi komthwalo olinganiselwe.
Izici zomkhiqizo
1. High motor amandla factor.isici sekhwalithi ephezulu yegridi.asikho isidingo sokwengeza isinxephezelo sesici samandla.amandla emishini yesiteshi esincane angasetshenziswa ngokugcwele;
2. Unomphela uzibuthe motor kuyinto unomphela uzibuthe excitation, operation synchronous, akukho ukushaya kwesivinini.Ngesikhathi sokudonsa abalandeli.amaphampu neminye imithwalo ayikukhulisi ukulahlekelwa ukumelana namapayipi;
3. ngokuvumelana nezidingo unomphela uzibuthe motor kungenziwa yakhelwe ibe high starting torque (izikhathi ezingaphezu kuka-3).umthamo omkhulu wokugcwala.ukuze kuxazululwe isenzakalo "sehhashi elikhulu elidonsa inqola encane";
4. i-current esebenzayo yamamotho ajwayelekile angama-asynchronous ngokuvamile cishe izikhathi ezi-0.5 kuya kwezingu-0.7 zamanje ezilinganiselwe, ama-motor synchronous kazibuthe we-Mingteng awadingi amandla amanje ajabulisayo.umehluko phakathi kwama-motor kazibuthe amanje asebenzayo anomphela kanye nama-asynchronous motors acishe abe ngu-50%, ukusebenza kwamanje kwangempela kucishe kube ngama-15% aphansi kunalawo ama-asynchronous motors;
5. I-motor ingaklanywa ukuthi iqale ngokuqondile, ukwakheka nosayizi wokufaka kuyafana nemoto yamanje esetshenziswa kabanzi e-asynchronous.ingabuyisela ngokugcwele injini ye-asynchronous.
Izicelo Zomkhiqizo
Imikhiqizo ewuchungechunge isetshenziswa kabanzi kumishini ehlukahlukene efana nabalandeli, amaphampu, imishini yebhande le-compressors yokucwenga emandleni kagesi, ukongiwa kwamanzi, uphethiloli, imboni yamakhemikhali, izinto zokwakha, insimbi, izimayini neminye imikhakha.
FAQ

Ukuvumelanisa kwe-6.Speed nokusebenza kokulawula okuhle kakhulu;
7.Ukukhuphuka kwezinga lokushisa kwehliswe ngaphezu kuka-20K.
Amaphutha ajwayelekile we-Frequency Converter?
1. Ngesikhathi sokulawula i-V/F, isiguquli se-frequency sibika iphutha lokuhlunga futhi sikhulise i-torque yokuphakamisa ngokuyimisa ukuze ikhulise i-torque ephumayo ye-motor futhi inciphise okwamanje ngesikhathi senqubo yokuqalisa;
2. Uma kusetshenziswa isilawuli se-V/F, lapho inani lamanje lenjini liphezulu kakhulu endaweni elinganiselwe yemvamisa futhi umphumela wokonga amandla uphansi, inani le-voltage elilinganiselwe lingalungiswa ukuze kuncishiswe lamanje:
3. Ngesikhathi sokulawula i-vector, kuba nephutha lokuzilungisa ngokwakho, futhi kuyadingeka ukuqinisekisa ukuthi amapharamitha we-nameplate alungile yini.Vele ubale ukuthi ubudlelwano obufanele bulungile yini ngo-n=60fp, i=P/1.732U
4. Umsindo wefrikhwensi ephezulu: umsindo ungancishiswa ngokwandisa imvamisa yenkampani yenethiwekhi, engakhethwa ngokuya ngamavelu anconyiwe kubhukwana;
5. Uma uqala, i-motor output shaft ayikwazi ukusebenza ngokujwayelekile: idinga ukuphindaphinda ukuzifundela noma ukuguqula imodi yokuzifundela;
6. Uma uqala, uma i-shaft ephumayo ingasebenza ngokujwayelekile futhi kubikwe iphutha elidlulele, isikhathi sokusheshisa singalungiswa;
7. Ngesikhathi sokusebenza, iphutha elidlulele liyabikwa: Uma amamodeli e-motor and frequency converter ekhethwa ngendlela efanele, isimo esijwayelekile ukugcwala kwemoto noma ukwehluleka kwemoto.
8. Iphutha le-overvoltage: Uma ukhetha ukuvala ukusheshisa, uma isikhathi sokunciphisa sisifushane kakhulu, singasingathwa ngokunweba isikhathi sokunciphisa, ukwandisa ukumelana namabhuleki, noma ukushintshela endaweni yokupaka mahhala.
9. Isiphambeko esifushane ukuya phansi: Ukuguga okungenzeka kwe-motor insulation, izintambo ezingezinhle ohlangothini lomthwalo wemoto, ukufakwa kwe-motor kufanele kuhlolwe futhi izintambo kufanele zihlolwe ukuthi ziphansi;
10. Iphutha eliphansi: I-converter ye-frequency ayigxiliwe noma injini ayisekelwe phansi.Hlola isimo sokumisa phansi, uma kukhona ukuphazamiseka eduze kwesiguquli sefrikhwensi, njengokusebenzisa ama-walkie talkies.
11. Ngesikhathi sokulawulwa kwe-loop evaliwe, amaphutha abikwa: izilungiselelo zepharamitha ye-nameplate engalungile, i-coaxiality ephansi yokufakwa kwe-encoder, i-voltage engalungile enikezwe isishumeli sekhodi, ukuphazamiseka kwekhebula lempendulo yesifaki khodi, njll.
