ZYBP medium and high frequency converter
●Ubuchwepheshe bokulawula iVector: Ngokulinganisa nokulawula i-stator current vector ye-AC motor, nokulawula i-excitation current kanye ne-torque yamanje yenjini ye-AC ngokulandelana ngokomgomo wokuma kwe-flux, inhloso yokulawula i-torque ye-AC motor iyafinyelelwa.
●Ubuchwepheshe bokucindezela i-oscillation: Ukungazinzi kwendawo kuzokwenzeka lapho injini ilayishwa kancane noma ingalayishiwe. Ngalesi sikhathi, i-amplitude yamanje ishintshashintsha kakhulu. I-oscillation ye-current ingase ibangele isistimu ukuthi icuphe ukuvikelwa ngenxa ye-overcurrent noma overvoltage. Inkampani yethu yamukela i-algorithm yamanje yokucindezela i-oscillation ephakeme kakhulu, engacindezela ngempumelelo i-oscillation yamanje futhi iqinisekise ukusebenza okuzinzile nokuthembekile kohlelo.
●Umsebenzi wokukhukhuleka wephoyinti elimaphakathi: Ngemva kokuthola iphutha leyunithi, iyunithi ingadlulwa phakathi kuka-100us ukuze yenze ubuchwepheshe be-star point drift ukuze kugcinwe ibhalansi kagesi ophumayo kanye nokwandisa ukusetshenziswa kwamandla kagesi.
●Ubuchwepheshe bokusetha kabusha okushisayo kweyunithi engalungile: Uma iyunithi yehluleka ngesikhathi sokusebenza futhi i-inverter iyidlulile futhi iqhubeka nokusebenza, iyunithi engalungile ingasethwa kabusha ngesikhathi sokusebenza ngaphandle kokulinda inverter ukuthi ime.
●Ubuchwepheshe bokuqala bokundiza ngokushesha: Ngokuqoqa imvamisa, ubukhulu, kanye nolwazi lwesigaba se-voltage ye-stator yemoto ngesikhathi sangempela, lapho kudingeka isiqalo endizayo, i-voltage yokuqala ye-inverter iyalungiswa ukuze ihambisane ne-stator voltage, bese i-voltage ephumayo ilungiswa ngokushesha ibe evamile ngalesi sisekelo. okukhiphayo. Ngokusebenzisa lobu buchwepheshe, isiguquli semvamisa singakwazi ukusetha kabusha ngokuzenzakalelayo bese siqala ngokuzenzakalelayo ngemva kokuvikelwa umthelela womthwalo, ngaleyo ndlela sigweme ukulahlekelwa okubangelwa ukuvala shaqa kokuvikela ukuguqulwa kwemvamisa ezenzakalweni ezibalulekile (njengamafeni ezinga lokushisa eliphezulu ezitshalweni zikasimende). Ubuchwepheshe bokuqalisa ukundiza okusheshayo buvumela isiguquli ukuthi sisethe kabusha sisuka kusimo sokuvikela phakathi nesekhondi elingu-1 futhi siqalise kabusha ukusebenza ngomthwalo.
●Ubuchwepheshe bokuxhumana obusebenzayo be-fiber optical: Umjikelezo wokuxhumana phakathi kwesilawuli esikhulu neyunithi ungu-1.5us, onokusebenza kahle kakhulu kokuxhumana kanye nokuxhumana okuhle kwesikhathi sangempela.
●Ukuguqulwa kwefrequency ibe imvamisa yamandla: Isiguquli sefrikhwensi siletha injini kufrikhwensi yamandla, ithola imvamisa, isigaba kanye nobukhulu begridi yamandla, bese ilungisa okukhiphayo kwesiguquli sefrikhwensi ukuze kube ifrikhwensi nesigaba njengefrikhwensi yamandla. Ngemuva kokuthi ukulungiswa sekuqediwe, xhuma injini kugridi yamandla bese unqamula ku-inverter.
●Ukushintshela kwefrikhwensi yamandla kufrikhwensi eguquguqukayo: Okokuqala, isiguquli sefrikhwensi sithola imvamisa, isigaba kanye nobukhulu begridi yamandla. Ngemva kokushintsha, isiguquli se-frequency sikhipha ngokuqondile i-vector ye-voltage ehambisanayo ku-motor, futhi ekugcineni siphuma ku-frequency yamandla. Lobu buchwepheshe bungahlangabezana nezidingo zokulawula okuphelele kwamamotho amaningi kanye nokuqalisa okuthambile kwamamotho amakhulu.
●Izindlela zokulawula eziningi: Ungakhetha isilawuli sendawo, isilawuli sebhokisi lesilawuli kude, isilawuli se-DCS, sisekela i-MODBUS, i-PROFIBUS, njll.
Iphrothokholi yokuxhumana, ukusetha imvamisa kunganikezwa kusayithi, kulingiswe ukude, kukhulunywe ngakho, njll., futhi isekela ukusetha kusengaphambili, ukusheshisa kanye nemisebenzi yokwehlisa izinga.
●Ubuchwepheshe bokuzinza kwamandla kagesi okukhiphayo: Isiguquli sefrikhwensi sithola amandla kagesi weyunithi ngayinye ngesikhathi sangempela futhi silungise i-coefficient yamandla kagesi okukhiphayo ngokuya nge-voltage yebhasi ukuze kuzuzwe umsebenzi wokuzinzisa ugesi ozenzakalelayo. Gwema umthelela wokuguquguquka kwegridi yamandla ku-voltage ephumayo.
●Imojuli yamandla eyakhelwe ngaphakathi ye-UPS: Lapho amandla okulawula okujikelezayo elahlekelwa amandla, azoshintshela ngokushesha ekunikezeni amandla okusekela kwe-transformer ku-inverter.
●Ukucisha kukagesi ngokushesha kanye nomsebenzi wokuqalisa kabusha wegridi yamandla: Isikhathi sokucisha kwamandla singasethwa, futhi inani elizenzakalelayo elivamile amasekhondi angu-3, elinganikeza isikhathi esiphezulu sokulinda samasekhondi angu-60.
