Uma usebenzisa isilawuli sezimboni sansuku zonke, izinto ezibalulekile zokukhethwa kwedivayisi yempendulo yamandla:
Layisha Izimpawu Zokufanisa
Ukulayisha njalo kwetorque (isb. amakhreni, ama-hoists) kudinga ukukhethwa kwezinsiza zokuphendula ezinokusabela okuphezulu okuguquguqukayo ukuze kuqinisekiswe ukumuncwa okusheshayo kwamandla avuselelekayo.
Imithwalo ye-torque eguquguqukayo (isb. amafeni, amaphampu amanzi) idinga ukulungisa umkhawulo wamandla empendulo ngokuya ngejika letorque yesivinini (isb. izici zetorque yesikwele).
Isilinganiso samandla ne-voltage
Amandla alinganiselwe wedivayisi yempendulo kufanele abe ≥ izikhathi ezingu-1.1 amandla alinganiselwe emoto, futhi i-voltage yebhodi lomama kufanele ifane nomthamo wegridi (njengezinhlelo ezingu-400V / 660V).
Amadivayisi anamandla amakhulu (>100kW) atusa iziguquli zefrikhwensi yamaquadrant amane ukuze zisekele ukugeleza kwamandla okuqondiswa kabili.
Ukuhambisana Kwegridi
Ibanga lokuguquguquka kwamandla kagesi wegridi (±20%) lidinga ukutholwa ukuze kuqinisekiswe ukuthi impendulo yamanje ye-harmonic distortion rate (THD) <5%.
Khetha amadivayisi ane-voltage/imvamisa yokutholwa kokuvumelanisa ukuze ugweme ukwehluleka kwempendulo kwamanje kanye negridi.
Ukuhlukaniswa kwezobuchwepheshe kanye nezimo zohlelo lokusebenza
Thayipha Isimo Sesici
Ukufakwa okuhlukene, kulula ukukugcina, kodwa kudinga izintambo ezengeziwe
Konke-kokukodwa kuhlanganiswe kusiguquli sefrikhwensi, impendulo esheshayo, izindleko eziphezulu Imishini emisha yezimboni (efana ne-centrifuge)
Isitoreji samandla esinephakethe lebhethri, sifanele izimo ezingaphandle kwegridi noma ezingazinzile ngaphandle kwempendulo yegridi
Ukuhlola Ukusebenza Komnotho Nemandla
Izinga lokonga amandla: idivayisi yempendulo ye-elevator yamandla ingaba ngu-17.85% -40.37%, kuyadingeka ukubala isikhathi sokubuyisela utshalomali ngokuhambisana nesilinganiso somthwalo.
Ukuqhathaniswa kwezindleko: Intengo yedivayisi yempendulo icishe iphindwe izikhathi ezingu-2-3 kunokusetshenziswa kwamandla kwebhuleki, kodwa izinzuzo zesikhathi eside zokonga amandla zibalulekile.
Ukufakwa Nokugcinwa
Ukupholisa design
Idivayisi yempendulo enamandla amakhulu idinga ukupholisa komoya okuphoqelekile (okufana nesiphephetha-moya esingaqhumi) ukuze kuqinisekiswe izinga lokushisa lebhondi le-IGBT elingu-<125 ℃.
≥100mm isikhala sokulahla ukushisa sigcinwe ngaphakathi kwekesi ukugwema ukunqwabelana kokushisa.
Umsebenzi wokuvikela
Kudingeka ukuvikelwa kwe-overvoltage, i-overcurrent, ukushisa ngokweqile kanye ne-grid backlash, njengokusika okuzenzakalelayo lapho i-voltage ye-motherboard idlula izikhathi ezingu-1.2 inani elisebenzayo legridi.
Izincomo zenqubo yokukhetha
Ukulinganisa ijika lomthwalo: Thola ukuphakama kwamandla avuselelekayo ngokuhlolwa kwesivinini se-torque.
Ukutholwa kwegridi: Qinisekisa okuqukethwe kwe-harmonic nokuzinza kwe-voltage yegridi.
Ukuqinisekiswa Kokulingisa: Ukusebenzisa amathuluzi afana ne-MATLAB ukulingisa ama-waveforms wamanje wempendulo ukuze kulungiselelwe amapharamitha okulawula.
