Abahlinzeki be-frequency converter units braking bakukhumbuza ukuthi ngokuthuthukiswa okuqhubekayo kwe-automation yezimboni, indima yeziguquli zefrikhwensi iya ngokuya ibaluleka. Ngezansi isingeniso esifushane sezinzuzo eziningi zokusebenzisa isiguquli semvamisa:
Okokuqala, kusetshenziswa i-cage type induction motor engabizi futhi kulula ukuyinakekela. Ngaphezu kwalokho, i-motor yokuqala yokungenisa ingasetshenziswa ngokuqondile ngaphandle kwesidingo sokuguqula imishini kanye nohlelo lokushayela, ithuthukise ukusebenza komshini.
2. Ingenza imisebenzi eqhubekayo futhi ebanzi. Uma usebenzisa amandla akhona asetshenziswa ngokuvamile, sebenzisa enye idivayisi yesivinini esishintshashintshayo (isinciphisi, ibhande lokushayela, njll.) ukuze ushintshe isivinini. Kodwa-ke, ingenza kuphela ukushintsha kwezigaba futhi ayikwazi ukwenza ukuguquka okuqhubekayo.
3. I-frequency converter ingashintsha injini ye-DC, lapho kusetshenziswa khona i-induction motor. Ngokufana nezinjini ze-DC, ayidingi amabhulashi, izindandatho zokushelela, njll., futhi inokugcinwa okuhle kakhulu nokumelana nemvelo.
4. I-converter ye-frequency ingaqalwa ngokuthambile futhi ivalwe kancane, futhi isikhathi sokusheshisa / sokunciphisa injini singalungiswa ngokuzenzakalelayo.
5. Nciphisa umsinga oqala ngawo. Ngokusebenzisa isiqalo esithambile kanye nokuma okuthambile kwesiguquli sefrikhwensi, isiqalo samanje singancishiswa sibe izikhathi ezi-1.5 kuye kwezingu-2 kunomanje olinganiselwe lapho injini iqala. Uma uqala ngokuqondile, isiqalo sokuqala sezikhathi ezingu-6 ukugeleza kwamanje okulinganiselwe, okuzobangela umthwalo ekusebenzeni okuvamile / ukumisa kwenjini.
6. I-rebound braking yesiguquli se-frequency kusiza ukubhuleka kukagesi.
7. Isiguquli sefrikhwensi esisodwa singasebenza ngokuhambisana ukuze silawule izinjini ezimbalwa.
8. Ukusebenza kahle okuphezulu.
9. Ukusebenzisa ama-frequency converters kumafeni okungenisa umoya, amaphampu amanzi, njll. kungonga amandla; Isetshenziselwa imishini yokupholisa umoya, ingakha indawo ekhululekile.
10. Ingakwazi ukusebenza ngesivinini esiphezulu ngaphezu kwamandla enjini.
11. Sebenzisa isilawuli sesivinini esiphezulu ukuze uthuthukise ikhwalithi.
Ngenxa yemisebenzi ehlukene yezinto zikagesi ezimbonini ezahlukene, umsebenzi wesiguquli semvamisa esisetshenzisiwe nawo uzohluka. Uma ukhetha ukucushwa kwesiguquli se-frequency, kuyadingeka ukubamba ngokugcwele izici zomthwalo.
1. Qinisekisa izici zomthwalo ezifana nohlobo lomthwalo, isivinini, kanye nemvelo;
2. Qinisekisa ukuthi ngabe kungukusebenza okuqhubekayo, ukusebenza kwesikhathi eside, ukusebenza kwesikhashana kanye nezinye izici zokusebenza;
3. Qinisekisa inani eliphezulu lokuphumayo kokusetshenziswa kanye nenani elilinganiselwe lokuphumayo;
4. Qinisekisa inani eliphezulu lokuzungezisa kanye nenani elilinganiselwe lokuzungezisa;
5. Qinisekisa uhla lokulawula isivinini;
6. Qinisekisa izinguquko kumthwalo, wamanje, amandla kagesi, imvamisa, izinga lokushisa, njll;
7. Qinisekisa ukunemba kokulawula okudingekayo;
8. Qinisekisa indlela yokubhuleka;
9. Qinisekisa ukucushwa kwamandla okokufaka. Okusho ukuthi, umthamo ukhethwa ngokusekelwe ezicini ezifana nezici ze-torque yesivinini, umthamo wokulayisha ngokweqile, ukulinganisa isikhathi, i-torque yokuqala, inani lokukhipha elilinganiselwe, imodi yokusebenza, imodi yokulawula, inombolo yokuguquguquka, amandla okusebenza kahle, njll.
Kodwa akulula ukukhetha ukucushwa kwesiguquli semvamisa ngale ndlela engenhla. Ngakho-ke, abasebenzisi abajwayelekile bangakhetha isiguquli semvamisa ngokususelwa ekucushweni kwemoto. Okokuqala, khetha i-voltage yokumisa (220V, 380V, 440V) bese ukhetha umthamo wokuguqula imvamisa ngokusekelwe kumthamo wenjini (kW). Ngokuvamile, imikhiqizo ene-torque ephansi yokuqala namandla okulayisha njengamafeni namaphampu amanzi isebenzisa izinjini zamandla angu-1: 1 kanye neziguquli zemvamisa; Kumakheshi, ama-cranes, namanye amadivaysi adinga ama-torque amaningi nemithwalo emikhulu, khetha isiguquli sefrikhwensi esinomthamo wesiteji esisodwa phezulu kunenjini.
