Abahlinzeki bemishini yokonga i-elevator bakukhumbuza ukuthi ukulawulwa kwamakheshi ngabaguquli befrikhwensi yekheshi kumise okwe-S, okusho ukuthi ukusheshisa ngesikhathi sokuqala nokuma kuthambile, kanti phakathi nenqubo emaphakathi, ukusheshisa kuyashesha, ikakhulukazi ukunethezeka kwabagibeli. Ukonga amandla nakho kuyisici esisodwa, okuyinzuzo evamile yeziguquli zefrikhwensi. Ngenxa yezinzuzo zayo ezifana nesekhethi elula, isici samandla aphezulu, ukonga amandla, ukuqala okushelelayo, nobubanzi besivinini esibanzi, amakheshi aguquguqukayo ama-voltage frequency athole ukuthuthuka okusheshayo.
Izidingo zokufaka ze-elevator frequency converter:
(1) Izidingo ezijwayelekile zendawo yokufaka:
Akukho ukugqwala, akukho magesi avuthayo noma aqhumayo noma uketshezi; Akukho ukuphazamiseka kwe-electromagnetic; Izintambo ezingenalo uthuli, ezintantayo kanye nezinhlayiya zensimbi; Ukuze ugweme ukukhanya kwelanga okuqondile, isisekelo nezindonga zendawo yokufaka kufanele ziqine, zingonakalisiwe, futhi zingadlidlizi.
(2) Izintambo zesiguquli sefrikhwensi:
Hlola ukuthi likhona yini iphutha lezintambo; Hlola ukuthi ingxenye eveziwe yezintambo zetheminali ixhumene yini nezingxenye ezibukhoma zamanye amatheminali nokuthi ithinta isikhwama se-converter frequency; Hlola ukuthi isikulufu siqinisiwe yini nokuthi izintambo zikhululekile yini;
(3) Ukuhlakazwa kwe-inverter cover plate:
Ngesikhathi sokufakwa, i-cover plate idinga ukuhlakazwa ukuze kuhlolwe, kuhlolwe, kufakwe izintambo, nokunye ukusebenza kusiguquli sefrikhwensi.
(4) Izinga lokushisa lemvelo:
Ngokuvamile ilungele ukusebenza ezindaweni ezinamazinga okushisa asukela ku -10 ℃ kuya ku-40 ℃ kanye namazinga omswakama angaphansi kuka-90%. Uma izinga lokushisa le-ambient lingaphezulu kuka-40 ℃, isiguquli sefrikhwensi kufanele sehliswe ngo-5% kukho konke ukukhuphuka okungu-1 ℃. (5) Isikhala sokufaka kanye nokungena komoya kwe-frequency converter: Isiguquli sefrikhwensi sifakwe isiphephetha-moya sokupholisa ngaphakathi ukuze sipholise umoya ngempoqo, futhi kufanele sifakwe sibheke phezulu; Uma ufaka iziguquli zefrikhwensi eziningi kudivayisi eyodwa noma ibhokisi lokulawula, kuyanconywa ukuthi uzifake zivundlile ngokuhambisana ukuze unciphise ukuthonya okushisayo okuhambisanayo.
(6) Izinyathelo zokuqapha zamasekhethi okulawula izintambo:
I-wiring phakathi kwesifunda sokulawula kanye nesifunda esikhulu, kanye ne-wiring phakathi kwesifunda sokulawula kanye nezinye izintambo zamandla, kufanele zihlukaniswe futhi zigcinwe ebangeni elithile; Itheminali yokuxhumana ye-relay ehola kumjikelezo wokulawula kufanele ihanjiswe ngokuhlukana nokuxhumeka kwamanye amatheminali wesifunda sokulawula ukuze kugwenywe izimpawu zokuphazanyiswa okubangelwa ukuvalwa kokuxhumana noma ukunqanyulwa; Ukuze uvimbele ukuphazamiseka okubangelwa umsindo nezinye izimpawu, izintambo ezivikelekile zisetshenziswa kumjikelezo wokulawula.
(7) Izinga lokushisa lemvelo:
Ngokuvamile ilungele ukusebenza ezindaweni ezinamazinga okushisa asukela ku -10 ℃ kuya ku-40 ℃ kanye namazinga omswakama angaphansi kuka-90%. Uma izinga lokushisa le-ambient lingaphezulu kuka-40 ℃, isiguquli sefrikhwensi kufanele sehliswe ngo-5% kukho konke ukukhuphuka okungu-1 ℃.
Isizathu sokusebenzisa i-variable frequency regulation kumakheshi:
(1) Izinyusi zokulawula isivinini esishintshashintshayo zifanele amamotho asynchronous, anezinzuzo zosayizi omncane, indawo encane yokuhlala, ukwakheka okulula, ukugcinwa okulula, ukwethembeka okuphezulu, kanye nenani eliphansi uma kuqhathaniswa namamotho e-DC anomthamo ofanayo.
(2) Ukunikezwa kwamandla okulawula isivinini esishintshashintshayo kusebenzisa ubuchwepheshe be-SPWM obuthuthukisiwe be-SVWM, obuthuthukisa kakhulu ikhwalithi nokusebenza kokusebenza kwekheshi; Ibanga elibanzi lejubane, ukunemba kokulawula okuphezulu, ukusebenza kahle okuguquguqukayo, ntofontofo, ethule, futhi esheshayo, kancane kancane selingene esikhundleni sokulawulwa kwejubane lemoto ye-DC.
(3) I-lifti yokulawula isivinini esishintshashintshayo isebenzisa ubuchwepheshe be-SPWM obuthuthukisiwe be-SVWM, obuthuthukisa kakhulu ikhwalithi yamandla kagesi, inciphisa ama-harmonics, ithuthukise ukusebenza kahle kanye nesici sokusebenza kahle, futhi yonga amandla kakhulu.
