Ingabe Idrayivu Yefrikhwensi Eguquguqukayo Ingathathelwa Indawo I-Motor Soft Starter?
Ngihlangana namakhasimende amaningi futhi angibuza imibuzo eminingi futhi ngihlonipheke kakhulu ukuhlangana nawo futhi ngikhulume nawo mayelana nokulawula ukuqala kwezimoto.Amanye amakhasimende ahlala ezibuza ukuthiama-frequency drivesingathathelwa indawoiziqalo ezithambile.Namuhla ngizokunikeza isiphakamiso:
1. Umgomo wokulawula we-soft starter kanye ne-frequency converter uhlukile
Isekhethi eyinhloko yesiqalisi esithambile ixhunywe ochungechungeni phakathi kokunikezwa kwamandla kanye nenjini kokuthathu okuphambene okuhambisanayo kwe-thyristor, ngokusebenzisa isekethe yangaphakathi yedijithali ukulawula i-thyristor ngendlela ephelele ye-waveform ye-sinusoidal yokushintshana kwesikhathi samanje sokuvula, uma ekuqaleni. womjikelezo we-AC vumela i-thyristor ivule, khona-ke i-voltage ephumayo yesiqalisi esithambile iphezulu, Uma i-thyristor ivulwa endaweni ethile emjikelezweni wamanje oshintshanayo, ukuphuma kwamandla kagesi kwesiqalisi esithambile siphansi.Ngale ndlela, senza i-voltage ekugcineni kwemoto ikhuphuke kancane kancane ngesikhathi sokuqala, bese silawula ukuqala kwamanje kanye ne-torque ye-motor, ukuze i-motor ikwazi ukufeza injongo yokuqala okuzinzile.Kungabonakala ukuthi i-starter ethambile ingashintsha kuphela izinga le-voltage yokunikezwa kwamandla, kodwa hhayi imvamisa yokunikezwa kwamandla.
Umgomo wokuguqula imvamisa uyinkimbinkimbi uma kuqhathaniswa.Umsebenzi wayo ukuguqula i-voltage engu-380V/220V kanye nemvamisa kagesi ongu-50HZ ibe idivayisi yokuguqula amandla e-AC ene-voltage eguquguqukayo kanye nemvamisa.Ngokulungisa imvamisa kanye nemvamisa yokunikezwa kwamandla, itorque nesivinini semoto ye-AC kungalungiswa.Isekhethi yayo eyinhloko iyisekhethi eyakhiwe ngamashubhu omphumela wensimu ayi-6, ngaphansi kokulawulwa okunembile kwesekethe yokulawula, ukuze amashubhu omphumela wensimu ayisithupha avule, ngesikhathi seyunithi, lapho inani leshubhu livuliwe, bese kuba amandla okukhipha amandla kanye nemvamisa. iphakeme, ngakho-ke isifunda esiyinhloko singaphansi kokulawulwa kwesifunda sokulawula idijithali ukuze kuzuzwe ukulawulwa kwemvamisa kokuphuma kwamandla okukhipha kanye nokulawulwa kwe-voltage.
2. Ukusetshenziswa kweisiqalo esithambilefuthi inverter zihlukile
Inkinga enkulu yesiqalisi esithambile ukunciphisa ukuqala komthwalo osindayo nokunciphisa umthelela kugridi yamandla.Ukuqaliswa kwemishini emikhulu kuzokhiqiza amandla amakhulu kakhulu okuqala, okuzobangela ukwehla okukhulu kwamandla kagesi.Uma imodi yendabuko yokuya phansi efana nonxantathu wenkanyezi isetshenziswa, ngeke nje ibangele umthelela omkhulu wamanje kugridi yamandla, kodwa futhi ibangele umthelela omkhulu womshini emthwalweni.Kulokhu, isiqalisi esithambile sivame ukusetshenziselwa ukuqala, ukuze kuqaliswe konke ukuqalisa ngaphandle komthelela futhi kwenze injini iqale ngokushelela.Ngakho amandla amancane.
Ukusetshenziswa kwei-frequency converterisetshenziswa kakhulu endaweni enomthethonqubo wejubane, ingakwazi ukulawula isivinini semoto enezigaba ezintathu, njengakulawulweni wejubane lomshini we-CNC we-spindle motor, i-mechanical conveyor belt control control, abalandeli abakhulu, izinhlelo zokusebenza ezinzima zingasetshenziswa isiguquli sefrikhwensi, ngokuvamile, umsebenzi waso sisebenza kakhulu kunesiqalisi esithambile.
3. Umsebenzi wokulawula we-converter frequency ye-soft starter uhlukile
Umsebenzi oyinhloko wesiqalisi esithambile ukulungisa i-voltage yokuqala yemoto ukuze ibone ukuqala kahle kwenjini ukuze kwehliswe umthelela wenjini emishinini nakugridi yamandla.Nokho, ngenxa yokuthi ilawula i-voltage nge-chopper ngokulawula i-Angle conduction, okukhiphayo akuphelele i-sine wave, okuholela kuthoshi yokuqala ephansi, umsindo omkhulu nama-harmonics aphezulu kuzongcolisa igridi yamandla.Nakuba isiqalisi esithambile sikhawulelwe ekusetheni umsebenzi wokusakaza, ukulungiselelwa kwesikhathi sokuqala neminye imisebenzi, kodwa ngesiguquli sefrikhwensi, amapharamitha okusebenza kwesiqalisi esithambile adidayo uma kuqhathaniswa.Ngokuvamile, umsebenzi we-soft starter awufani ne-converter frequency.
4. Intengo yesiqalisi esithambile ihlukile kuleyo yesiguquli sefrikhwensi
Amadivayisi okulawula amabili asesimweni samandla esifanayo, kusukela enanini le-inverter liphezulu kunesiqalisi esithambile.
Ngokuvamile, isiqalisi esithambile sisetshenziswa kakhulu kumishini yamandla aphezulu njengemishini yokuqala, futhi isiguquli semvamisa sisetshenziswa kakhulu ukulawula isivinini samandla ahlukahlukene.Ezimweni eziningi, isiguquli sefrikhwensi asinakushintshwa yisiqalisi esithambile.
