Mukushandiswa kunoshanda kwe frequency converter, mamwe matambudziko asingatarisirwe anozoonekwa nguva nenguva, zvakanyanya nekuti vashandisi vemota havazive zvakawanda nezve hukama pakati pe frequency converter uye mota, kunyanya mune mamwe akakosha mashandisirwo emota, matambudziko akafanana anowedzera kusimba. .
(1) Kana iyo inverter ichishandiswa kudzora mota-inochinja mota, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune kugona kutevedza kweiyo inverter, kuitira kuti ive nechokwadi chekuti yakayerwa ikozvino yemota iri pasi pe nhamba dzakasiyana dzemapango haina kukwira kupfuura yakayerwa. yakabuda ikozvino inobvumirwa ne inverter, kureva kuti, iyo yakarongwa ikozvino ye inverter haigoni kuva yakaderera pane yakarongwa motokari yegiya guru remotokari;Uye zvakare, iyo pole nhamba shanduko yemota inofanirwa kuitwa kana mota yamira kushanda, kuitira kudzivirira misoperation ye overvoltage kana overcurrent kudzivirira.
(2) Iyo frequency converter inoshandiswa kudzora ma-high-speed motors, nekuti torque ye-high-speed motors idiki, uye iyo yakakwirira harmonics ichawedzera kukosha kwazvino.Naizvozvo, pakusarudza frequency converter, huwandu hweiyo frequency converter hunofanirwa kunge hwakakura kupfuura hwemota yakajairika.
(3) Kana iyo mota inoputika-yekudzivirira ichienderana neiyo frequency converter, inofanirwa kuenderana nekuputika-uchapupu frequency converter zvinoenderana nezvinodiwa chaizvo, zvikasadaro inofanira kuiswa munzvimbo isina njodzi.
(4) Kana iyo frequency converter ichishandiswa kudzora ronda rotor mota, yakafanana nekutonga kweyepamusoro-kumhanya mota.Nekuti iyo mhepo inotenderedza yerudzi urwu mota idiki, inofanirwa kuenderana neiyo frequency converter ine yakakura huwandu;Uyezve, nekuda kwekunyanya kurongeka kweronda, kumhanya mushure mekushandura frequency kunofanirwa kuenderana nekushivirira kwemuchina wemota rotor.
(5) Kana iyo inverter ichishandiswa kudzora iyo inonyudza pombi mota, yakayerwa ikozvino yerudzi urwu rwemota yakakura kupfuura yeyakajairika mota.Naizvozvo, pakusarudza iyo inverter, zvinodikanwa kuve nechokwadi kuti yakayerwa ikozvino inotenderwa neiyo inverter yakakura kupfuura iyo yemota, uye hazvigoneke kungosarudza mhando zvinoenderana neyakajairwa mota.
(6) Pamamiriro ekushanda kwemotor ane mitoro yakasiyana-siyana, senge compressors uye vibrators, mota dzakadaro dzinowanzo kuve nesevhisi zvinodiwa, kureva kuti, mutoro uye mota yazvino yakakura kupfuura kukosha kwepamusoro kwesimba rakajairwa.Paunenge uchisarudza frequency converter, hukama hunoenderana pakati peiyo yakatemerwa kubuda ikozvino uye peak ikozvino inofanirwa kutariswa zvizere kudzivirira misoperation yezviito zvekudzivirira panguva yekushanda.
(7) Kana iyo inverter ichidzora iyo synchronous mota, nekuti simba reiyo synchronous mota rinochinjika, huwandu hweiyo synchronous mota hunogona kuita hudiki pane iyo yekudzora simba frequency mota, iyo inowanzo deredzwa ne10% kusvika 20%.
Pamusoro pezviri pamusoro apa, panogona kunge paine mota dzine mamwe mashandisiro uye maitiro.Pakusarudza frequency converter, isu tinofanirwa kunyatso tarisa maitiro emota uye mamiriro ekushanda, uye kuona ma frequency ekushandura paramita uye kushanda mushure mekuongorora kwakazara.
