Isiqendu sokuqala: Intshayelelo kuisiguquli sefrikhwensi
Isiguquli samaza amaninzi, esaziwa ngokuba yi-i-variable frequency drive (VFD), sisixhobo sokuguqula amandla esilawula kwaye silawula isantya semoto yombane. Ngokulawula i-frequency kunye ne-voltage enikezelwa kwimoto, i-frequency converter inokulawula ngokuchanekileyo isantya kunye ne-torque yemoto. Ezi zixhobo ziguquguqukayo zisetyenziswa kumashishini ahlukeneyo, ukusuka kwiinkqubo zokuvelisa kunye ne-HVAC ukuya kumandla ahlaziyekayo kunye nothutho. Kule blog, siza kuhlola amandla ee-frequency converters, sixoxe ngeenzuzo zazo, kwaye sikhanyise indima yazo ebalulekileyo ekuphuculeni ukusebenza kakuhle kunye nokonga iindleko.
Isiqendu sesibini: Umgaqo wokusebenzaisiguquli sefrikhwensi
Isiguquli sefrikhwensi siguqula ifrikhwensi emiselweyo kunye nevolthi yombane wokufaka ibe yifrikhwensi ehlengahlengiswayo kunye nevolthi, senza i-variable frequency output efanelekileyo yokuqhuba iintlobo ezahlukeneyo zeemoto. Ngokulungisa ifrikhwensi yokufaka, isiguquli sefrikhwensi sinokulawula isantya semoto. I-incoming alternating current (AC) ilungiswa kuqala kusetyenziswa i-rectifier ize iguqulwe ibe yi-direct current (DC). Isekethe ye-inverter emva koko isetyenziselwa ukuguqula i-DC voltage ibuyele kwi-AC voltage ngefrikhwensi ehlengahlengiswayo kunye nevolthi. Le AC output ehlengahlengiswayo ifakwa kwimoto, ivumela ulawulo oluchanekileyo lwesantya sayo kunye ne-torque.

Ukongeza, i-frequency converter inika imisebenzi yokuqalisa nokumisa ethambileyo, ngaloo ndlela inciphisa uxinzelelo loomatshini kwaye yandisa ubomi benkonzo yeemoto kunye noomatshini. Ukongeza, ii-frequency converters zisusa imfuneko yolawulo loomatshini olufana nee-throttles kunye nee-dampers, okwenza kube lula ukuntsonkotha kwenkqubo kunye nokugcinwa kwayo.
Isiqendu 4: Ukusetyenziswa kweisiguquli sefrikhwensi
Ii-frequency converters zisetyenziswa kakhulu kumashishini ahlukeneyo. Kwimveliso, zisetyenziswa koomatshini abanjengoothuthi, iipompo kunye neecompressor ukuze kuphuculwe ukusetyenziswa kwamandla kunye nokwenza lula ulawulo lwemigca yemveliso. Ii-variable speed drives nazo ziyinxalenye ebalulekileyo yeenkqubo ze-HVAC zanamhlanje, ezivumela ulawulo oluchanekileyo lwee-ventilators, ii-chillers kunye neepompo ukuphucula intuthuzelo kunye nokusebenza kakuhle kwamandla. Kwiinkqubo zamandla avuselelekayo ezifana nee-wind turbines kunye neepaneli zelanga,abaguquli befrikhwensizidlala indima ebalulekileyo ekuguquleni amandla e-DC aguquguqukayo-frequency aveliswayo abe ngamandla e-AC ahambelana negridi. Ukongeza, ii-frequency converters zisetyenziswa kwiinkqubo zombane zokuqhubeleka kwezithuthi ukulawula isantya semoto kunye ne-torque, okuvumela ukusetyenziswa kwamandla ngokufanelekileyo kunye nokwandisa ubomi bebhetri.
Isiqendu 5: Izinto ekufuneka ziqwalaselwe xa ukhetha i-inverter
Xa ukhethaisiguquli sefrikhwensi, kukho izinto ezininzi ekufuneka ziqwalaselwe. Okokuqala, umlinganiselo wamandla kufuneka uhambelane neenkcukacha zamandla emoto ukuqinisekisa ukuhambelana. Uluhlu lwamandla kunye nolwamaza e-inverter kufuneka luhambelane nombane okhoyo. Ukongeza, amaqhinga okulawula, njengolawulo lwe-voltage vector okanye ulawulo lwe-torque ngqo, kufuneka avavanywe ngokusekelwe ekusebenzeni kwemoto okufunekayo. Kubalulekile ukumisela iimpawu zokhuseleko ezifunekayo, ezinje ngokhuseleko lwamandla agqithisileyo kunye nokhuselo lwamandla agqithisileyo, ukukhusela imoto kunye ne-inverter kumonakalo onokubakho. Okokugqibela, ukulula kokufakela, ukuba lula ukuyisebenzisa kunye nokufumaneka kweenkonzo zenkxaso yomenzi zizinto ezibalulekileyo ngokulinganayo.
