Rau cov motors txuas nrog zaus converters, qhov siab tshaj plaws saum npoo yuav tsum tau txiav txim siab los ntawm txoj kev sim nyob rau hauv feem ntau unfavorable tej yam kev mob
- Feem ntau cov xwm txheej tsis zoo
(1) Torque / ceev yam ntxwv
Rau cov motors siv rau qhov sib txawv torque loads, qhov siab tshaj plaws saum npoo kub yuav tsum tau ntsuas ntawm lub zog siab tshaj plaws ntawm qhov siab tshaj plaws ntsuas ceev; rau cov motors siv rau linear loads thiab tas li torque loads, qhov siab tshaj plaws saum npoo kub yuav tsum tau ntsuas qhov tsawg kawg nkaus thiab siab tshaj speeds; rau lub cev muaj zog siv rau kev thauj khoom nyuaj, qhov siab tshaj plaws ntawm qhov kub thiab txias yuav tsum ntsuas tsawg kawg ntawm qhov inflection point ntawm qhov nrawm-torque nkhaus.
(2) Qhov kub siab tshaj plaws saum npoo yuav tsum ntsuas qhov tsawg kawg nkaus thiab qhov siab tshaj plaws ntawm lub zog tas li.
(3) Voltage poob
Thaum lub sij hawm tsim thiab commissioning ntawm lub tswv yim, qhov voltage poob ntawm tag nrho cov Cheebtsam yuav tsum tau xav txog. Yog li ntawd, cov ntaub ntawv hais txog qhov voltage poob ntawm zaus converter, lim, voltage poob raws cable, system configuration thiab zaus converter input voltage yuav tsum to taub. Cov lus qhia npaj los ntawm cov chaw tsim khoom raws li Tshooj 30 ntawm GB / T 3836.1-2021 "Explosive Atmospheres Part 1: General Requirements for Equipment" yuav tsum muab tag nrho cov ntaub ntawv tsim nyog los pab txhawb kev suav / teeb tsa ntawm kev ua haujlwm.
(4) Inverter tso zis yam ntxwv.
Tsawg switching zaus yuav ua rau kom lub cev muaj zog kub. Cov kev ua haujlwm tshwj xeeb yuav tsum tau hais kom meej qhov tsawg kawg nkaus hloov zaus; multilevel inverters (3 lossis siab dua) feem ntau ua rau txo lub cev muaj zog cua sov.
(5) Coolant Qhov siab tshaj qhov ntsuas kub ntsuas nrog qhov ntsuas qhov tsawg kawg nkaus / siab tshaj qhov ntsuas qhov ntsuas kub; tshwj xeeb kev khiav hauj lwm tej yam kev mob yuav tsum tau qhia kom meej cov coolant yuav tsum tau.
- Cov kev sim
(1) Kev txiav txim siab inverter motors yuav tsum tau sim nrog lub hom phiaj inverter. Yog hais tias lub inverter tso zis voltage thiab harmonic cov ntsiab lus ntawm cov zis voltage waveform yog zoo ywj siab ntawm ± 10% input voltage variations thaum tuav lub ntsuas lub cev muaj zog input tam sim no (ceev nyob rau hauv) thiab voltage thiab zaus, qhov qub ± 10% input voltage variation yuav tsum tsis. siv.
(2) Zoo sib xws inverters Thaum muaj cov ntaub ntawv txaus los txiav txim siab zoo sib xws, lub cev muaj zog tuaj yeem sim nrog cov inverter zoo sib xws. Feem ntau, lwm yam kev nyab xeeb yog siv los suav rau qhov zoo sib xws raws li qhov tsim nyog. Yog hais tias lub inverter tso zis voltage thiab harmonic cov ntsiab lus ntawm cov zis voltage waveform yog zoo ywj siab ntawm ± 10% input voltage variations thaum tuav lub ntsuas lub cev muaj zog input tam sim no (ceev nyob rau hauv) thiab qhov voltage thiab zaus piv, qhov qub ± 10% input voltage variation yuav tsum tsis txhob siv.
(3) Sinusoidal voltage motors tsis tas yuav tsum tau kuaj nrog lub inverter zoo sib xws, tab sis tuaj yeem kuaj nrog sinusoidal voltage raws li tag nrho cov hauv qab no: qhov xav tau load torque yog proportional rau lub square ntawm ceev; lub cev muaj zog yuav tsum raug rau qhov siab tshaj plaws ntawm kev ntsuas ceev; lub cev muaj zog ceev ntau ntawm 40% thiab 100% ntawm qhov siab tshaj plaws ntsuas ceev;
