I-voltage sag inokuqondwa njengokuhla ngequbuliso kumbane olandelwa kukubuyela okufutshane kwisiqhelo.Ke ujongana njani nephenomenon ye-voltage sag?Okokuqala, kufuneka sijongane nayo kwimiba emithathu yokuvelisa i-voltage sag kunye nokwenza ingozi.I-voltage sag ngokubanzi yingxaki yenkqubo yobonelelo lwamandla, kwaye ngokubanzi ngumenzi wezixhobo kunye nomsebenzisi wokwenyani owonzakeleyo kwaye uchatshazelwa yi-voltage sag.Ukulungelelaniswa kwezi zintathu kuyafuneka ukulawula ngempumelelo i-voltage sag.ukufikelela kwimeko yokusebenza eqhelekileyo yesixhobo.Ukunciphisa kakhulu iingozi ezininzi ezibangelwa yi-voltage sags.
Ukuyibeka ngokulula, ngokuqhelekileyo ngenxa yesiphoso kumgca wokunikezelwa kwamandla, inani le-voltage sags liya kwanda.Ke ngoko, kufuneka sinciphise inani lokungaphumeleli kwaye sinciphise ixesha lokusombulula ingxaki, kwaye siphucule uzinzo lokusebenza kwenkqubo yonikezelo lwamandla kunye nokusebenza kwezixhobo zamandla.Ngokwandisa ngokufanelekileyo ubume benkqubo yonikezelo lwamandla, imveliso ezinzileyo yothumelo lwamandla kunye nenkqubo yokuhambisa iyandiswa.Kwangaxeshanye, fakela izixhobo ezahlukeneyo zokulungisa amandla, njengaphakathi kojongano olwahlukeneyo lwenkqubo kunye nezixhobo.Okokugqibela, intsebenziswano phakathi kwabavelisi bezixhobo kunye nabasebenzisi iyafuneka ukuze kuphuculwe isakhono sesixhobo sokumelana nokusetyenziswa kwamandla ombane kunye nokunciphisa umonakalo obangelwe zii-voltage sags.
Kwingxaki yenkqubo yokubonelela ngombane.Okokuqala, ingxaki ye-voltage sag idla ngokubangelwa ziziphoso ezahlukeneyo kwimigca yenkqubo yonikezelo lwamandla (uninzi lwazo ziingxaki ezimfutshane ezibangelwa yi-capacitance encinci yemigca yendawo).Ngexesha elifanayo, ixesha lokusombulula impazamo lide kakhulu, kwaye akukho ndlela efanelekileyo yokubonelela ngombane kubasebenzisi bokwenene.Ngokukodwa ukuphindaphinda kwee-voltage sags kwezinye iindawo zixhaphakile kwaye ixesha lide kakhulu, ngokwesiqhelo inkqubo yonikezelo lwamandla kufuneka ijongwe kuqala.Ngokubanzi, ukuze utshintshe ingxaki ye-voltage sag, ngokuqhelekileyo kuyimfuneko yokongeza imigca kunye nezixhobo zokusasaza.Oku kuya kwandisa kakhulu iindleko zegalelo, ezifuna ukuba isebe lokubonelela ngombane libeke iliso ngokuchanekileyo umgangatho wombane.Ukubonelela ngenkxaso yedatha yokwanda okulandelayo kobuntununtunu besixhobo kunye nesisombululo semiba yobuntununtunu besixhobo.
Kubenzi bezixhobo, ukusebenza okuqhelekileyo kunye nomsebenzi wezixhobo kufuna indawo yokusebenza efanelekileyo.Ngokunciphisa ubuntununtunu besixhobo esisetyenzisiweyo kwi-voltage sags, i-misoperations evela kwi-automation okanye i-semi-automation inokuncitshiswa ukuya kuthi ga kwinqanaba elithile.Oku kuvumela izixhobo zombane ukuba zibe nesakhono esithile sokuxhathisa i-voltage sags.Kwangaxeshanye, ukuba i-voltage sag ibangelwa ngokuthe ngqo kukuqala kwe-motor enkulu, sinokutshintsha isiqalo esinzima kwisiqalo esithambileyo okanye sandise umthamo we-short-circuit yendawo yokudibanisa eqhelekileyo ukusombulula le ngxaki.
Kubasebenzisi bokwenene.Oku kufuna ukufakelwa kwezixhobo zembuyekezo phakathi kwezixhobo zomsebenzisi, ezifana nokutshintsha kwemeko eqinileyo, unikezelo lwamandla olungaphazamisekiyo, ukubuyisela amandla ombane aguqukayo, njl.
Zintathu kuphela ezihambelanayo.Ukuze ufumane indawo efanelekileyo yamandla ombane.
