ZYBP medium and high frequency converter
●I-teknoloji yokulawula i-Vector: Ngokulinganisa kunye nokulawula i-stator ye-vector yangoku ye-motor ye-AC, kunye nokulawula i-excitation yangoku kunye ne-torque yangoku ye-motor ye-AC ngokulandelanayo ngokomgaqo we-flux orientation, injongo yokulawula i-torque ye-motor ye-AC ifezekisiwe.
●Itekhnoloji yoxinzelelo lwe-oscillation: Ukungazinzi kwendawo kuya kwenzeka xa i-motor ilayishwa kancinci okanye ingalayishwanga. Ngeli xesha, i-amplitude yangoku iguquguquka kakhulu. I-oscillation yangoku inokubangela ukuba inkqubo iqalise ukukhuselwa ngenxa ye-overcurrent okanye overvoltage. Inkampani yethu yamkela i-algorithm ephezulu yoxinzelelo ye-oscillation yangoku, enokuthi icinezele ngokufanelekileyo i-oscillation yangoku kwaye iqinisekise ukusebenza okuzinzileyo nokuthembekileyo kwenkqubo.
●Indawo engathathi hlangothi yokuqhuba umsebenzi: Emva kokubona impazamo yeyunithi, iyunithi inokugqithwa ngaphakathi kwe-100us ukwenza itekhnoloji ye-star point drift ukugcina ibhalansi yombane ophumayo kunye nokwandisa ukusetyenziswa kwamandla ombane.
●I-teknoloji ephosakeleyo yokusetha kabusha iteknoloji: Ukuba iyunithi iyahluleka ngexesha lokusebenza kwaye i-inverter iye yadlula kwaye iyaqhubeka nokusebenza, iyunithi ephosakeleyo inokuphinda isetyenziswe ngexesha lokusebenza ngaphandle kokulinda ukuba i-inverter imise.
●Itekhnoloji yokuqalisa ukubhabha ngokukhawuleza: Ngokuqokelela amaza, i-amplitude, kunye nolwazi lwesigaba se-voltage ye-stator yemoto ngexesha lokwenyani, xa kufuneka isiqalo sokubhabha, i-voltage yokuqala ye-inverter iyahlengahlengiswa ukuze ihambelane nombane we-stator, emva koko i-voltage ephumayo ihlengahlengiswa ngokukhawuleza ibe yesiqhelo kwesi siseko. imveliso. Ukusebenzisa le teknoloji, i-frequency converter inokusetha ngokuzenzekelayo kwaye emva koko iqalise ngokuzenzekelayo emva kokukhuselwa yimpembelelo yomthwalo, ngaloo ndlela igweme ilahleko ebangelwa ukuvalwa kokukhuselwa kokuguqulwa kwamaxesha kwiimeko ezibalulekileyo (ezifana nabalandeli bokushisa okuphezulu kwizityalo zesamente). Itekhnoloji yokuqalisa ukubhabha ngokukhawuleza yenza ukuba i-inverter ikwazi ukuseta kwakhona ukusuka kwindawo yokukhusela ngaphakathi kwe-1 yesibini kwaye iqalise ukusebenza ngomthwalo.
●Itekhnoloji yonxibelelwano lwefiber optical esebenzayo: Umjikelo wonxibelelwano phakathi kolawulo oluphambili kunye neyunithi yi-1.5us, enonxibelelwano oluphezulu kakhulu kunye nonxibelelwano oluhle lwexesha lokwenyani.
●Ukuguqulwa okuphindaphindiweyo kwifrikhwensi yamandla: Isiguquli sefrikhwensi izisa i-motor kwi-frequency yamandla, ibona i-frequency, isigaba kunye ne-amplitude yegridi yamandla, kwaye emva koko ilungelelanise ukuphuma kwe-converter frequency ukuze ibe kwi-frequency kunye nesigaba njenge-frequency yamandla. Emva kokuba ulungelelwaniso lugqityiwe, qhagamshela i-motor kwigridi yamandla kwaye emva koko unqamule kwi-inverter.
●Ukutshintshela i-frequency frequency kwi-frequency frequency: Okokuqala, i-frequency converter ibona i-frequency, isigaba kunye ne-amplitude yegridi yamandla. Emva kokutshintsha, isiguquli se-frequency sikhupha ngokuthe ngqo i-vector ye-voltage ehambelanayo kwi-motor, kwaye ekugqibeleni iphuma kwi-frequency yamandla. Le teknoloji inokwanelisa iimfuno zolawulo olubanzi lweemoto ezininzi kunye nokuqala okuthambileyo kweenjini ezinomthamo omkhulu.
●Iindlela ezininzi zokulawula: Unokukhetha ulawulo lwendawo, ulawulo lwebhokisi yokulawula kude, ulawulo lwe-DCS, inkxaso ye-MODBUS, i-PROFIBUS, njl.
Iprothokholi yonxibelelwano, useto lwefrikhwensi lunokunikwa kwisiza, ukulinganisa kude, ukunxibelelana, njl., kwaye ixhasa ukusetha kwangaphambili, ukukhawuleza kunye nemisebenzi yokunciphisa.
●Itekhnoloji yokuphuma kwamandla ombane wokuzinzisa amandla ombane ozenzekelayo: Isiguquli sefrikhwensi sibona umbane webhasi kwiyunithi nganye ngexesha lokwenyani kwaye uhlengahlengiso i-coefficient yombane ophumayo ngokombane webhasi ukufezekisa umsebenzi wokuzinzisa umbane ozenzekelayo. Gwema impembelelo yokuguquguquka kwegridi yamandla kwi-voltage ephumayo.
●Imodyuli eyakhelwe-ngaphakathi ye-UPS yamandla: Xa i-peripheral control power supply ilahlekelwa amandla, iya kutshintshela ngokukhawuleza kwi-backup power supply ye-transformer kwi-inverter.
●Ukuphela kombane ngokukhawuleza kunye nomsebenzi wokuqalisa kwakhona kwegridi yamandla: Ixesha lokuphuma kwamandla linokusetwa, kwaye ixabiso elimiselweyo jikelele liyimizuzwana emi-3, enokunika ixesha elide lokulinda lemizuzwana engama-60.
