Ungawakhetha kanjani ama-converter ahlukahlukene ukuze ulayishe?Uma kukhona isiguquli sefrikhwensi esikhethekile sokulayisha, isiguquli esikhethekile sizokhethwa.Uma singekho isiguquli sefrikhwensi, isiguquli esijwayelekile singakhethwa kuphela.
Yiziphi izici ezintathu ezihlukene zomthwalo we-inverter?Abantu bavame ukuhlukanisa umthwalo ngokuzijwayeza ube yi-torque load engashintshi, amandla ahlala njalo kanye nomthwalo wefeni kanye nepompo.
Ukulayisha njalo kwe-torque:
I-torque TL ayihlobene nesivinini n, futhi i-TL ihlala ingashintshile kunoma yisiphi isivinini.Isibonelo, imithwalo ye-friction efana namabhande okuthutha kanye nezixube, amandla anamandla afana namakheshi nama-cranes, konke kungokwemithwalo ye-torque engaguquki.
Lapho i-inverter ishayela umthwalo nge-torque engaguquki, idinga ukusebenza ngesivinini esiphansi kanye nesivinini esiqinile, ukuze i-torque ibe nkulu ngokwanele futhi umthamo wokulayisha ungonele.Okokugcina, ukuchithwa kokushisa kwe-asynchronous motor ejwayelekile kuzocatshangelwa ukuvimbela ukukhuphuka kwezinga lokushisa okweqile kwemoto.
Amandla ahlala njalo:
I-torque yomshini wephepha, i-uncoiler nokunye ukucaciswa kuhambisana ngokuphambene nesivinini n.Lokhu kungumthwalo wamandla njalo.
Isakhiwo samandla esingaguquki somthwalo siyashintsha ngaphakathi kwesivinini esithile.Uma ukulawulwa kwesivinini kwenza inkambu ibe buthaka, itorque enkulu evunyelwe yokukhiphayo ilingana nesivinini, okuwukulawulwa kwesivinini samandla njalo.
Lapho ijubane liphansi kakhulu, ngenxa yokulinganiselwa kwamandla emishini, i-torque TL inenani eliphakeme kakhulu, ngakho-ke izoba i-torque engaguquki.
Umthamo omncane we-motor kanye ne-frequency converter yilapho ububanzi bamandla angashintshi kanye ne-torque engaguquki ye-motor efanayo naleyo yomthwalo.
Umthwalo wefeni nepompo:
Ngokusho komkhiqizi we-Chuangtuo Electric Frequency Converter, ngokunciphisa ijubane elijikelezayo labalandeli, amaphampu nezinye izinto zokusebenza, i-torque iyancipha ngokwesikwele sejubane elijikelezayo, futhi amandla alingana namandla esithathu ejubane.Esimeni sokonga amandla, isiguquli sefrikhwensi sizosetshenziswa ukulungisa ivolumu yomoya futhi sigeleze ngokulawulwa kwesivinini.Ngenxa yokuthi amandla adingekayo akhula ngokushesha ngesivinini ngesivinini esikhulu, umthwalo wabalandeli namaphampu akufanele udlule imvamisa yamandla.
