Ukuqonda Umehluko
Umqondo wamanje olinganiselwe uvame ukuvela ezingxoxweni ezimayelanaizinjini zikagesi. Kuwuhlaka olubalulekile abakhiqizi abalucacisayo ukuze bachaze imikhawulo yokusebenza ephephile yenjini. Kodwa ingabe izilinganiso zamanje ziwumthamo omkhulu wamanje ongaphathwa injini? Lo mbuzo udinga ukuqonda okuguquguqukayo kwezimo ezahlukahlukene zokusebenza kwezimoto nezindlela zokuvikela.
Ikalwe okwamanje: Isisekelo
Incazelo: Umthamo wamanje olinganiselwe amandla amaningi aqhubekayo injini engakwazi ukuwuthwala ngokuphepha ngaphansi kwezimo ezithile zokusebenza (isb., i-voltage, imvamisa, izinga lokushisa le-ambient) ngaphandle kokushisisa ngokweqile noma ukubangela umonakalo ekushiseni kwemoto.
Inhloso: Isilinganiso samanje ipharamitha yokuklama esetshenziselwa ukukhetha ama-circuit breaker, ama-conductor, nezinye izingxenye zikagesi ezifanele. Iqinisekisa ukuthi injini isebenza ngaphakathi kwemingcele yayo ephephile futhi ivimbela izimo zokugcwala ngokweqile.
Ubuningi Bamanje: Umbono Obanzi
Ukulayisha ngokweqile kwesikhashana:Izimotongokuvamile ingamelana namagagasi aphezulu isikhathi esifushane, njengalapho iqalisa noma lapho ishayela imithwalo esindayo. Lokhu kungenxa ye-inertia eshisayo ye-motor, evumela ukuthi ikhiphe ukushisa ngokuhamba kwesikhathi.
Inani eliphakeme kakhulu lamanje: Kwezinye izinhlelo zokusebenza, izinjini zingase zibe namaza aphezulu adlula kakhulu inani elilinganiselwe. Lokhu kuvame kakhulu kuinduction ac motorlawula izinhlelo ezisebenzisa i-pulse-width modulation (PWM) ukulawula isivinini semoto kanye netorque.
Izimo zephutha: Ngesikhathi sezimo zephutha, njengesekhethi emfushane, i-current ngokusebenzisa injini ingakhuphuka kakhulu. Amadivayisi okuvikela, njengama-circuit breaker, aklanyelwe ukuphazamisa ukugeleza kwamanje ngaphambi kokuba injini yonakaliswe.
Izinto Ezithinta Ubuningi Bamanje
Idizayini yemoto: Idizayini yemoto, okuhlanganisa izinto ezisetshenziswayo, izindlela zokupholisa, kanye nesigaba sokufakwa kwe-insulation, inquma umthamo wayo oshisayo nekhono lokumelana nama-overcurrents.
Izimo zokusebenza: Izinga lokushisa elizungezile, ukushintshashintsha kwamandla kagesi, nokulayisha ngomshini kungase kuthinte izinga lokushisa lemoto futhi, ngenxa yalokho, amandla ayo aphezulu avumelekile.
Amadivayisi okuvikela: Izinqamuli zesekhethi, ama-fuse, nokugcwala okushisayo kwe-thermal kuklanyelwe ukuvikela injini kumthamo wamanje oweqisayo. Izici zabo zokukhubeka zithonya umthamo omkhulu wamanje ongatholwa injini ngaphambi kokuthi umjikelezo uphazamiseke.
Nakuba isilinganiso samanje simele umkhawulo wokusebenza ophephile wenjini ngaphansi kwezimo ezijwayelekile, kubalulekile ukuqaphela ukuthi amamotho angakwazi ukuphatha amaza aphezulu isikhathi esifushane noma ngaphansi kwezimo ezithile. Ubukhulu bamanje injini engakwazi ukubekezelela buncike ezintweni ezihlukahlukene, okuhlanganisa ukwakheka kwemoto, izimo zokusebenza, kanye nemishini yokuvikela ekhona.
