Njengoba sonke sazi, indawo ekahle yokuphakelwa kwamandla esithemba ukuyithola ukuthi isistimu yegridi yokuphakela amandla ingasinikeza i-voltage ezinzile.Uma sihlangabezana nokwehla kwesikhashana noma ukwehla kwamandla kagesi (imvamisa ukwehla okungazelelwe, kubuyela kokujwayelekile ngesikhathi esifushane).Okusho ukuthi, isenzakalo sokuthi inani elisebenzayo le-voltage yokuhlinzeka lehla ngokuzumayo bese liyakhuphuka futhi lilulame ngesikhathi esifushane.I-International Institute of Electrical and Electronics Engineers (IEEE) ichaza ukwehla kwamandla kagesi njengokwehla ngokushesha kwevelu esebenzayo ye-voltage yokuhlinzeka ukuya ku-90% kuya ku-10% yenani elilinganiselwe.%, bese ikhuphukela emuva eduze nenani elivamile, ubude besikhathi bungu-10ms~1min.Uma ukwehla kwamandla kagesi kwenzeka, kuzoletha umonakalo omkhulu embonini.Ngoba i-voltage sag ithathwa njengenkinga yekhwalithi yamandla eyingozi kakhulu ekukhiqizweni kwezimboni.
Ngokuvamile, i-voltage sag izothinta zonke izinto zikagesi ezixhunywe kusekethe.Ikakhulukazi kulezo zimboni ezikhiqizayo nezicubungulayo ezidinga ukunemba okuphezulu, uma ukwehla kwamandla kagesi kuhlangatshezwana nayo, kuzodala ukulahleka nokumoshakala kwemikhiqizo enemba kalula.Okubaluleke nakakhulu, kuholela ekutheni inani elikhulu lezinto zokusetshenziswa zingasebenziseki.Kuphinde kube yingozi enkulu empilweni yemishini kagesi.Ngesikhathi esifanayo, i-voltage sag izophinde ibangele inani elikhulu lama-harmonics.
Izimboni eziningi manje zisebenzisa okokusebenza okuzenzakalelayo noma okuzenzakalelayo.I-voltage sag ingaholela ekwahluleleni okungalungile kwemishini ezenzakalelayo noma ezenzakalelayo.Ukuthi kubangele ukumiswa okwesikhashana noma ukungasebenzi kahle.Konke kungabangela isiguquli sefrikhwensi ukuthi sime, futhi kubangele nezisetshenziswa ezihlukahlukene zokuvikela amandla kagesi ukuthi ziqale.Kunezinhlobo ezahlukene zama-motor ezivamile ekuphileni kwansuku zonke.Isibonelo, amakheshi nama-TV azoma futhi abangele ukuthi injini iqale kabusha ngokuzumayo.
Uma lezi zisetshenziswa zikagesi zingakwazi ukusebenza ngokujwayelekile, ngenxa yesigameko esivele kungazelelwe, wonke ulayini wokukhiqiza uzophazamiseka.Lapho sidinga ukubuyiselwa okuhlelekile kwawo wonke umugqa wokukhiqiza.Kulingana nokwenyusa izindleko zesikhathi kanye nezindleko zabasebenzi ngeze.Ikakhulukazi kulezo zindawo ezinezidingo ngezinsuku zokudiliva nezokukhiqiza.
Izoba namuphi umthelela empilweni yansuku zonke?Umuzwa onembile kakhulu ukuthi uzodala umonakalo ohlelweni lwekhompiyutha, okuzodala ukuvala shaqa nokulahleka kwedatha kalula (ikhompyutha izocisha ngokuqondile, kungakhathaliseki ukuthi mangaki amagama owafakile futhi wawalungisa, kuyobe sekwephuzile kakhulu ukuwagcina. ngenxa yokuvalwa okungazelelwe).Ikakhulukazi lezo zindawo ezibaluleke kakhulu, njengemishini yasesibhedlela, uhlelo lomyalo wethrafikhi nokunye.Isibonelo esilula kakhulu.Igumbi lokuhlinzela lesi sibhedlela liyahlinzwa.Uma kukhona i-voltage sag, kungakhathaliseki ukuthi isibani esingenathunzi noma ezinye izinsimbi eziyinkimbinkimbi kakhulu, uma ivaliwe futhi iqalwa kabusha, izoba nomthelela omkhulu ekusebenzeni.Lolu hlobo lokwehluleka okubangelwa ingozi yensimbi alwamukeleki kuwo wonke umuntu.
Kuzilawuli ze-elekthronikhi zesiqandisi, uma kwenzeka i-voltage sag, isilawuli sizonqamula injini yesiqandisi.Embonini yokukhiqiza ama-chip, uma i-voltage isingaphansi kuka-85%, izodala ukuthi isekethe ye-elekthronikhi ingasebenzi kahle.
Idivayisi ebucayi yokulawula ukwehla kwamandla kagesi embonini ekhiqizwa yi-Hongyan Electric ingaxazulula ngempumelelo uchungechunge lwemiphumela edalwe ukuwohloka kwamandla kagesi.I-HY uchungechunge olubucayi lwemishini yokulawula i-voltage ye-sag - ukuphakama komkhiqizo kokuthi: ukuthembeka okuphezulu, okuklanyelwe ngokukhethekile imithwalo yezimboni, ukusebenza kahle kwesistimu, ukuphendula okusheshayo, ukusebenza kwesilungisisi esiphezulu, akukho mjovo we-harmonic, idijithali egcwele esekelwe kubuchwepheshe bokulawula i-DSP, ukwethembeka okuphezulu, ukuhambisana okuthuthukisiwe umsebenzi wokunweba, idizayini eyimojula, imisebenzi eminingi enesibonisi sombala weqiniso we-TFT.
