Ungazikhetha njani iziguquli zefrikhwensi ezahlukeneyo zomthwalo?Ukuba kukho isiguquli esikhethekileyo somthwalo, isiguquli esikhethekileyo siyakukhethwa.Ukuba akukho siguquli samaza, isiguquli samaza ngokubanzi sinokukhethwa kuphela.
Ziziphi iimpawu ezintathu ezahlukeneyo zomthwalo we-inverter?Abantu bahlala behlula umthwalo ekusebenzeni kumthwalo oqhubekayo wetorque, umthwalo oqhubekayo wamandla kunye nefeni kunye nomthwalo wempompo.
Umthwalo wetorque rhoqo:
I-torque TL ayihambelani nesantya n, kwaye i-TL ihleli ngokusisiseko kuyo nayiphi na isantya.Umzekelo, imithwalo yokukhuhlana enje ngeebhanti zokuthutha kunye nezixube, imithwalo yamandla enokubakho enje ngeelevator kunye neecranes, zonke zezomthwalo ongaguqukiyo wetorque.
Xa i-inverter iqhuba umthwalo nge-torque eqhubekayo, kufuneka isebenze ngesantya esiphantsi kunye nesantya esizinzile, ukwenzela ukuba i-torque ibe yinto enkulu ngokwaneleyo kwaye umthamo wokulayisha unokwanela.Okokugqibela, ukuchithwa kobushushu bemotor esemgangathweni ye-asynchronous kuya kuqwalaselwa ukuthintela ukunyuka kobushushu obugqithisileyo bemoto.
Umthwalo wamandla rhoqo:
I-torque yomatshini wephepha, i-uncoiler kunye nezinye iinkcukacha zihambelana ngokuphambene nesantya n.Lo ngumthwalo wamandla rhoqo.
Ipropathi yamandla engaguqukiyo yomthwalo iyatshintsha ngaphakathi kwesantya esithile.Xa isantya solawulo lwesantya sisenza buthathaka, eyona torque iphezulu evumelekileyo ihambelana nesantya, esilulawulo lwesantya samandla rhoqo.
Xa isantya siphantsi kakhulu, ngenxa yokunciphisa amandla omatshini, i-torque ye-TL inexabiso eliphezulu, ngoko iya kuba yi-torque rhoqo.
Ubuncinci bomthamo wemoto kunye ne-frequency converter kuxa uluhlu lwamandla angaguqukiyo kunye ne-torque engaguqukiyo yemoto ifana naleyo yomthwalo.
Umthwalo wefeni kunye nempompo:
Ngokomvelisi weChuangtuo Electric Frequency Converter, kunye nokunciphisa isantya esijikelezayo sabalandeli, iimpompo kunye nezinye izixhobo, i-torque iyancipha ngokwesikwere sesantya esijikelezayo, kwaye amandla alingana namandla wesithathu wesantya.Kwimeko yogcino lwamandla, isiguquli samaza siya kusetyenziswa ukulungisa umthamo womoya kunye nokuhamba kulawulo lwesantya.Ngenxa yokuba amandla afunekayo akhula ngokukhawuleza ngesantya esiphezulu, umthwalo wabalandeli kunye neepompo akufanele udlule umbane wamandla.
