Ukuze sikwazi ukuthenga ikhebula lokuguqula imvamisa efanele, kusamelwe siqhathanise ikhwalithi yekhebula, kodwa futhi sicabangele ukuthi intengo iyafaneleka yini. Uma kuqhathaniswa nezinye izintambo ezivamile, ikhebula le-inverter ngokwalo liphezulu kakhulu, futhi linezakhiwo ezithile zokuvikela, ngakho-ke kusamelwe sinake kakhulu ikhwalithi ethile yekhebula.
Izici
Izintambo ze-inverter zisahlukile kancane kwezinye izinhlobo zezintambo, futhi uma sifuna ukuthenga ikhebula elifanele, kubalulekile futhi ukuqonda izici zalo. I-voltage ye-impulse yalolu hlobo lwekhebula inomthelela omkhulu ekushiseni, futhi ikhebula ngokwalo lizokhipha amagagasi kagesi emhlabeni wangaphandle, ngakho-ke kubalulekile ukucabangela isimo sokuphazamiseka. Ngaphezu kwalokho, ukusetshenziswa kwezintambo ezinjalo kuzovela ku-neutral line current superposition, njll., ngakho izici zalo zisabonakala kakhulu, futhi zihluke ngokuphelele kwezintambo ezivamile.
Phela, izici zekhebula lokuguqulwa kwemvamisa zihlukile, izindawo zokufaka isicelo nazo zisekhebulani zinezidingo eziqinile, ngakho-ke ukuthengwa kwezintambo kufanele futhi kunake izidingo eziyisisekelo zesimo. Lezi zintambo kumele zibe nekhono lokuvimbela i-voltage ephezulu ye-harmonic ebangelwa ukuwohloka kokushisa, kodwa futhi nokugwema inkinga yokugcwala ngokweqile komugqa ongathathi hlangothi, ukuze zikwazi ukungcoliswa kwamagagasi kagesi aphezulu emvelo, ukuze amaphrojekthi afanele akwazi ukufeza imiphumela emihle yesicelo.
Ukuqinisekisa ikhwalithi
Ngenxa yokuthi ububanzi bemvamisa yokunikezwa kwamandla okuguqulwa kwemvamisa bubanzi kakhulu, kungaba imvamisa ephezulu noma imvamisa ephansi, uma ikhwalithi yekhebula ingekho kahle kakhulu, kungenzeka ukuthi kuthinte ukusetshenziswa okulandelayo kwekhebula, futhi kudale nezingozi ezithile. Konke kanye nokunikezwa kwamandla e-inverter kuzovela kugagasi elihambayo ngemva kokuzindla okuningi, okuholela ekwandeni kwe-voltage, okuphindwe kaningana kune-voltage yokusebenza. Ngakho-ke lapho sithenga izintambo ezinjalo, kumelwe siqinisekise ikhwalithi yazo.
Ikakhulukazi kweminye yemisebenzi ebaluleke kakhulu, ukusetshenziswa kwekhebula lokuguqula imvamisa elifanele, ukuphepha kwephrojekthi yisiqinisekiso, kodwa futhi nokugwema ukuthinteka enkingeni. Zama ukuthenga ikhebula kumkhiqizo ojwayelekile, ungasebenza ngqo nomkhiqizi, ukuze ukwazi futhi ukujabulela intengo yokuthengisa ngqo efektri.
