Kumamotho axhunywe kuziguquli zefrikhwensi, izinga lokushisa eliphezulu eliphezulu lizonqunywa izindlela zokuhlola ngaphansi kwezimo ezingezinhle kakhulu
- Izimo ezingezinhle kakhulu
(1) Izici ze-torque/isivinini
Kumamotho asetshenziselwa imithwalo ye-torque eguquguqukayo, izinga lokushisa eliphezulu eliphezulu lizolinganiswa ngamandla amakhulu ngesivinini esilinganiselwe esiphezulu; kumamotho asetshenziselwa imithwalo yemigqa kanye nemithwalo ye-torque engaguquki, izinga lokushisa eliphezulu elingaphezulu kufanele likalwe okungenani ngesivinini esincane nesiphezulu; kumamotho asetshenziselwa imithwalo eyinkimbinkimbi, izinga lokushisa eliphezulu eliphezulu lizolinganiswa okungenani endaweni yokuguquguquka yejika le-torque yesivinini.
(2) Izinga lokushisa eliphezulu eliphezulu lizokalwa ngesivinini esincane kanye nesivinini esiphezulu ngamandla angashintshi.
(3) Ukwehla kwamandla kagesi
Ngesikhathi sokuklama nokusetshenziswa kohlelo, ukwehla kwamandla kagesi kuzo zonke izingxenye kufanele kucatshangelwe. Ngakho-ke, ulwazi mayelana nokwehla kwe-voltage yesiguquli se-frequency, isihlungi, ukwehla kwamandla kagesi kukhebula, ukumiswa kwesistimu kanye ne-voltage yokufaka yokuguqula imvamisa kufanele kuqondwe. Imiyalo elungiselelwe umkhiqizi ngokuvumelana neSahluko 30 se-GB/T 3836.1-2021 "I-Explosive Atmospheres Ingxenye 1: Izimfuneko Ezivamile Zezisetshenziswa" kufanele inikeze lonke ulwazi oludingekayo ukuze kube lula ukubala/ukusetha ububanzi bokusebenza.
(4) Izici zokukhishwa kwe-inverter.
Amafrikhwensi aphansi okushintsha avame ukwandisa izinga lokushisa lemoto. Izimo zokusebenza ezikhethekile zingadingeka ukuze ucacise amafrikhwensi amancane okushintsha; ama-inverters amaleveli amaningi (3 noma ngaphezulu) ngokuvamile aholela ekwehliseni ukushisa kwemoto.
(5) Ukupholisa Izinga lokushisa eliphakeme kakhulu elikalwa ngokugeleza okulinganiselwe okulinganiselwe/izinga eliphezulu lokushisa elikalwe ngokupholisa elilinganiselwe eliphakeme; izimo zokusebenza ezikhethekile zingadingeka ukuze ucacise izidingo zokupholisa.
- Izindlela zokuhlola
(1) Ama-inverter motors azinikezele kufanele ahlolwe nge-inverter ehlosiwe. Uma i-voltage ephumayo ye-inverter kanye nokuqukethwe kwe-harmonic kwe-waveform ye-voltage ephumayo kuzimele ngempumelelo ekuhlukeni kwe-voltage yokufaka engu-±10% kuyilapho kugcinwa isilinganiso samanje sokufakwayo kwemoto (incike ngesivinini) kanye ne-voltage kanye nemvamisa, ukuhluka okujwayelekile okungu-±10% kagesi akudingekile. zisetshenziswe.
(2) Ama-inverters afanayo Uma kunolwazi olwanele lokunquma ukufana, injini ingahlolwa ngama-inverters afanayo. Ngokuvamile, izici zokuphepha ezengeziwe zisetshenziselwa ukulandisa ngokufana njengoba kufanele. Uma i-voltage ye-inverter ephumayo kanye nokuqukethwe kwe-harmonic kwe-waveform ye-voltage ephumayo kuzimele ngempumelelo ekuhlukeni kwe-voltage yokufaka engu-±10% kuyilapho kugcinwa isilinganiso samanje sokufakwayo kwemoto (incike ngesivinini) kanye nesilinganiso se-voltage ne-frequency, ukuhluka okuvamile okungu-±10% kagesi wokufaka. akudingeki isetshenziswe.
(3) Ama-motor we-Sinusoidal voltage awadingi ukuhlolwa nge-inverter efanayo, kodwa angahlolwa nge-voltage ye-sinusoidal ngaphansi kwazo zonke lezi zimo ezilandelayo: i-torque yomthwalo olindelekile ilingana nesikwele sejubane; injini kufanele ibe ngaphansi komthwalo omkhulu ngesivinini esilinganiselwe; isivinini semoto siphakathi kuka-40% no-100% wesivinini esilinganiselwe esiphezulu;
