Ukuzivumelanisa nezimo kwemikhiqizo ehlukile ye-inverter kumvelo

Ukuzivumelanisa nezimo kwemikhiqizo ehlukile ye-inverter kumvelo

1. Ikhono lokuzivumelanisa nokuguquguquka kwamandla kagesi kugridi yamandla

Lapho ama-motors ebhasini eqalwa ngamaqembu futhi kuqalwa amayunithi amakhulu ezithuthi ebhasini, umthelela ekusebenzeni kwesiguquli semvamisa uhlobene nemingcele yamandla wokuguquguquka kwamandla kagesi evumelekile yesiguquli semvamisa. Okokusebenza kwamandla kagesi, lapho i-voltage yebhasi yehla ngo-30%, inverter akufanele ime.

Ngaphezu kwalokho, ngemuva kokwehluleka kwamandla kwamandla webhasi okwenzeka ngokushesha, i-inverter kufanele ibe nomsebenzi wokuqhubeka noma wokuqalisa kabusha ukusebenza (abanye abakhiqizi bohlobo lwe-inverter bakubiza ngokuthi "umsebenzi wokuqalisa kabusha wokwehla kwamandla kagesi"), okungukuthi, lapho i-voltage yebhasi iyashesha uma yehla noma inyamalala (njengokushintshwa ngengozi), isiguquli semvamisa ngeke sikhubeke noma sibangele ukuthi uhlelo lwezimoto lusebenze ngokungaphelele; lapho i-voltage yebhasi ibuyela kokujwayelekile, isiguquli semvamisa singalungisa ngokukhipha umphumela waso ngokuya ngejubane lemoto elithunjiwe, bese sidonsela imoto ukugijima futhi.

2. Amandla okuzivumelanisa nemvelo esesizeni

Ama-inverters amaningi anamandla amakhulu afakwe eduze kwemishini esizayo esizeni, futhi kukhona uthuli oluningi. Uthuli olungena kwikhabethe le-inverter luzodala ukuthi ungqimba lwe-insulation lwehle noma lonakalise izinto ze-elekthronikhi; isihlungi esingenalo uthuli sizodala ukushabalalisa ukushisa kwekhabethe lamandla, okungaholela kalula ekwehluleni okweqile nokulimaza imodyuli yamandla. Abanye abakhiqizi baklama isihlungi somoya ukuthi sisuswe futhi sihlanzeke ngesikhathi sokusebenza ukwenza lula ukugcinwa. Ezindaweni ezinamazinga okushisa aphezulu nomswakama ophezulu eningizimu, imikhiqizo engadingi izinga lokushisa eliphakeme kakhulu nomswakama futhi enokuphakama kokushisa kwesistimu ephansi kufanele ikhethwe ukuqinisekisa ukusebenza okuphephile nokuzinzile.
