Ekusetshenzisweni kwansuku zonke kweziguquli zemvamisa ekulawuleni imboni, izimfuneko eziyinhloko zokukhethwa kweyunithi yempendulo zimi kanje:
Layisha Izimpawu Zokufanisa
Umthwalo we-torque njalo (njenge-crane, i-hoist): iyunithi yempendulo eqhubekayo ene-torque ye-braking ≥ 150% kufanele kukhethwe, futhi amandla afana namandla alinganisiwe enjini.
Umthwalo we-torque oguquguqukayo (njengefeni, iphampu yamanzi): amandla weyunithi yempendulo yomsebenzi wokukhanya angancishiswa ngegiya elilodwa (i-torque yokubhuleka 110%, isistimu yokusebenza engu-1/4).
Umthwalo onomthelela (isb. umshini wokugaya, umshini wokubhoboza): amagiya amabili akhuphukayo kanye namayunithi amabhuleki amisiwe.
Isilinganiso samandla ne-voltage
Iyunithi yempendulo elinganisela amandla≥ukukhiqiza amandla okuguqula imvamisa, izinga le-voltage kufanele lihambisane ne-voltage yokufaka yesiguquli sefrikhwensi (efana no-400V / 660V).
Uma usebenzisa i-synchronous motor, amandla eyunithi yempendulo adinga ukuba igiya elilodwa elikhulu kune-asynchronous motor.
Isistimu yokusebenza kanye nokuchithwa kokushisa
Uhlelo lokusebenza lwesikhashana (isilinganiso sokungenzi lutho ≤50%) singanciphisa ukukhethwa kwamandla, futhi uhlelo lokusebenza oluqhubekayo ludinga ukukhethwa izikhathi ezingu-1.2 amandla emoto.
Imvelo yokushisa ephezulu (> 40 ℃) idinga ukunciphisa ukusetshenziswa, ukwanda ngakunye kwe-1 ℃ ukuncishiswa kwe-1%.
Imingcele yezobuchwepheshe kanye nezidingo zesitifiketi
Ukuhambisana kwe-Harmonic kanye ne-electromagnetic
Ukukhishwa kwamanje kwe-Harmonic kufanele kuhlangabezane ne-IEC 61000-3-2 (THD <5%).
Ukuguquguquka kwamandla kagesi kanye nokuhlolwa okukhanyayo kufanele kuhlangabezane ne-EN 61000-3-3 (Pst≤1, Plt≤0.65).
Umsebenzi wokuvikela
Idinga u-overvoltage, i-overcurrent, isivikelo sokushisa ngokweqile, i-voltage ye-motherboard idlula izikhathi ezingu-1.2 i-voltage yegridi inqanyulwe ngokuzenzakalelayo.
Umsebenzi wokuthola isiqhingi esisodwa ukuze uqinisekise isikhathi sokuphumula esiphephile lapho igridi yamandla ingajwayelekile.
Iseluleko sezomnotho nokufaka
Izinzuzo Zokonga Amandla
Idivayisi yempendulo yekheshi ingonga kufika ku-15% -45%, isikhathi sokuthola kabusha utshalomali cishe iminyaka emi-2-3.
Izisetshenziswa zamandla aphezulu (>100kW) zincamela iziguquli zefrikhwensi yamaquadrant amane, ezinezinzuzo ezibalulekile zokonga amandla zesikhathi eside.
Ukufakwa Nokugcinwa
Idizayini epholise umoya eyimpoqo (njengebanga lokuvikela le-IP54) ukuze kuqinisekiswe izinga lokushisa lebhondi le-IGBT elingaphansi kuka-125 ℃.
≥100mm isikhala sokupholisa kufanele sigcinwe ukuze kugwenywe ukunqwabelana kokushisa.
