Phakathi nenqubo yokukhiqiza, ama-motor avame ukulimala ngenxa yokusebenza okungalungile, okungabangeli nje ukulahlekelwa kwezimali kodwa futhi kunomthelela omkhulu ekuqhubekeleni phambili kokukhiqiza. Ngakho-ke, ukusetshenziswa okulungile kwe-frequency converters kunomphumela omuhle ekuvikeleni ama-motor. Inkampani yethu ifinyeze ukuvikelwa kwamamotho ngabaguquli bamafrikhwensi ekusebenziseni ukuguqulwa kwefrikhwensi yemoto ngale ndlela elandelayo:
ukuvikelwa kwe-overvoltage
Okukhiphayo kwesiguquli sefrikhwensi kunomsebenzi wokuthola i-voltage, futhi isiguquli sefrikhwensi singalungisa ngokuzenzakalelayo i-voltage ephumayo ukuze ivimbele injini ukuthi imelane nokugcwala kwamandla. Noma ngabe ukulungiswa kwe-voltage okukhiphayo kwehluleka futhi i-voltage ephumayo idlula u-110% we-voltage evamile, isiguquli sefrikhwensi sisazovikela injini ngokuvala shaqa.
Ukuvikelwa kwe-undervoltage
Lapho i-voltage ye-motor ingaphansi kuka-90% we-voltage evamile, ukuvikelwa kokuguqula imvamisa kuyama.
ukuvikelwa kwe-overcurrent
Lapho i-current motor idlula imizuzwana engu-150%/3 yenani elilinganiselwe, noma ama-microseconds angu-200%/10 wamanje olinganiselwe, isiguquli semvamisa sivikela injini ngokuvala.
ukuvikelwa kwesigaba sokulahlekelwa
Gada i-voltage ephumayo. Uma kukhona ukulahleka kwesigaba kokuphumayo, isiguquli sefrikhwensi sizokhala i-alamu. Ngemva kwesikhathi esithile, isiguquli semvamisa sizoma ukuze sivikele injini.
Ukuvikelwa kwesigaba sokuhlehla
Isiguquli sefrikhwensi sivumela injini ukuthi ijikeleze kuphela ohlangothini olulodwa futhi ayikwazi ukusetha isiqondiso sokuzungeza. Ngaphandle kwalapho umsebenzisi eshintsha ukulandelana kwesigaba sezintambo zamamotho A, B, no-C, akukho nokwenzeka kwesigaba sokuhlehla.
ukuvikelwa kokulayisha ngokweqile
Isiguquli sefrequency siqapha amandla emoto. Uma i-motor current idlula u-120% wamanje olinganiselwe umzuzu ongu-1, isiguquli sefrikhwensi siyama ukuze sivikele injini.
ukuvikela phansi
Isiguquli sefrikhwensi sifakwe isekethe yokuvikela ephansi, evame ukuhlanganisa ama-transformer okuvikela aphansi kanye nama-relay. Uma isigaba esisodwa noma ezimbili zimisiwe, isiguquli sefrikhwensi sizokhala i-alamu. Kunjalo, uma kucelwe umsebenzisi, singaphinda sidizayine ukuze sivikele ukuvala shaqa ngokushesha ngemva kokubekwa phansi.
ukuvikelwa kwesifunda esifushane
Ngemuva kokuthi okukhiphayo kwesiguquli sefrikhwensi kufinyeziwe, kuzodala i-overcurrent nakanjani. Ngaphakathi kwama-microsecond ayi-10, isiguquli semvamisa sizoma ukuze sivikele injini.
Ukuvikelwa kwe-overfrequency
Isiguquli sefrikhwensi sinemisebenzi yomkhawulo wefrikhwensi ephezulu nobuncane, ekhawulela imvamisa yokuphumayo ebangeni elishiwo, ngaleyo ndlela ithola umsebenzi wokuvikela i-overclocking.
Ukuvikelwa kwetafula
Ukuvikelwa kwetafula kuvame ukusetshenziswa kumamotho ahambisanayo. Kumamotor asynchronous, i-stall ngesikhathi sokusheshisa ibonakala ngokudlulele, futhi isiguquli semvamisa sifeza lo msebenzi wokuvikela ngokuvikela okudlulele kanye nokulayisha ngokweqile. Ukuma ngesikhathi sokuncishiswa kungagwenywa ngokubeka isikhathi esiphephile sokwehlisa izinga ngesikhathi senqubo yokulungisa iphutha.
