Isingeniso
Imoto yokungenisa yesigaba sesithathu ye-squirrel cageAma-s asetshenziswa kabanzi ngamadivayisi okushayela kagesi asebenza kahle ngenxa yezici ezahlukahlukene, kanti i-supply voltage ingenye yezibaluleke kakhulu. Lesi sihloko sizohlola umthelela we-supply voltage ekusebenzeni kokusebenza kwama-squirrel cage amathathu-phase induction motors futhi sihlole izindlela eziyisisekelo.
Umphumela Wokushintshashintsha Kwe-Supply Voltage Ekusebenzeni Kwemoto
• I-Torque Yokuqala: Uma i-voltage yokunikezela yehla, i-torque yokuqala ye-injini kagesiizokwehla kakhulu. Lokhu kungenxa yokuthi i-torque yokuqala ilingana nesikwele se-voltage. Lapho i-voltage yehla, insimu yamagnetic ekhiqizwa yi-motor iba buthaka, okuholela e-torque yokuqala enganele engase yehluleke ukunqoba umthwalo, okubangela ukuthi i-motor ingaqali noma ibe nesikhathi eside sokuqala.
• I-Torque Ephakeme: Njenge-torque yokuqala, i-torque ephezulu nayo ilingana nesikwele se-voltage. Lapho i-voltage yehla, i-torque ephezulu nayo izokwehla, okuthinta ukuzivumelanisa kwemoto nezinguquko zomthwalo.
• Ugesi Osebenzayo: Uma i-voltage yokunikezela yehla, injini idinga ukudonsa ugesi owengeziwe ukuze ikhiqize i-torque efanayo. Ugesi oweqile ungandisa ukulahlekelwa kwethusi, okuholela ekushiseni okukhulu kwenjini ngisho nasekushiseni.
• Ukusebenza kahle: Uma i-voltage yokuphakelwa yehla, ukusebenza kahle kwemoto kuzokwehla. Lokhu kungenxa yokulahlekelwa okukhulu kwethusi kuyilapho amandla okukhipha ehla, okuholela ekusebenzeni kahle okuphansi.
• Isici Samandla: Umphumela wokunciphisa i-supply voltage ku-power factor uyinkimbinkimbi kakhulu; ngokuvamile, isici samandla sizoncipha kancane.
• Isivinini: Ngaphansi komthwalo olinganiselwe, umthelela wokunciphisa i-voltage yokunikezwa kwejubane mncane kakhulu. Kodwa-ke, ngaphansi kwezimo zokukhanya noma ezingenamthwalo, ukwehla kwe-voltage kungabangela ukwanda okuncane kwejubane. Umthelela Wokuguquguquka Kwe-Voltage Kuma-Motor
• Ukuguquguquka Kwesikhathi Esifushane: Ukuguquguquka kwamandla kagesi kwesikhathi esifushane kungaholela ekushayweni kwe-torque enjinini, okuthinta ukuzinza komthwalo. Ukuguquguquka okukhulu kungabangela ukuthi injini ishise ngokweqile noma idlidlize ngomshini.
• Ukuguquguquka Kwesikhathi Eside: Ukuguquguquka kwamandla kagesi kwesikhathi eside kungasheshisa ukuguga kokufakwa kwe-motor insulation, kufinyeze isikhathi sayo sokuphila. Kungathinta nokusebenza kahle kwemoto kanye nesici samandla.
Isifinyezo
I-voltage yokunikezela iyisici esibalulekile esithonya ukusebenza kweimoto yokungenisa yesigaba sesithathu ye-squirrel cages. Ukwehla kwamandla kagesi kuholela ngqo ekunciphiseni amandla okuqala kanye namandla amakhulu, ukwanda kwamandla kagesi okusebenza, kanye nokwehla kokusebenza kahle. Ukushintshashintsha kwamandla kagesi kungathinta ukuzinza, isikhathi sokuphila, kanye nokusebenza kahle kwemoto.
Izinyathelo zokuzivikela
• Ukuzinza Kwe-Voltage: Ukuqinisekisa ukusebenza okuvamile kwemoto, kubalulekile ukugcina ukuzinza kwe-voltage yokuphakelwa.
• Isinxephezelo se-Voltage: Ezimweni ezinokuguquguquka okukhulu kwe-voltage, cabanga ngokusebenzisa iziqinisi ze-voltage nomaidrayivu yemvamisa eguquguqukayos ukuze uthole isinxephezelo se-voltage.
• Ukukhetha Injini: Uma ukhetha injini, khetha efanelekile izici zomthwalo kanye nezimo zokunikezwa kwamandla, okuvumela ukuthi kube nesilinganiso esithile.
• Ukulungiswa Okuvamile: Hlola njalo ukusebenza kokushisa kwenjini bese ushintsha izingxenye ezindala ngesikhathi esifanele.
