Njengoko sonke sisazi, indawo efanelekileyo yobonelelo lwamandla esinethemba lokuyifumana kukuba inkqubo yonikezelo lwamandla ombane inokusinika amandla ombane azinzileyo.Xa sidibana nokuhla kwexeshana okanye ukuhla kwamandla ombane (ngokuqhelekileyo ukuhla ngokukhawuleza, kubuyela kwisiqhelo ngexesha elifutshane).Oko kukuthi, isenzeko sokuba ixabiso elisebenzayo lombane wobonelelo lehla ngequbuliso lize liphakame kwaye liphinde libuyele kwakhona ngexesha elifutshane.Iziko laMazwe ngaMazwe leeNjineli zoMbane nezoMbane (IEEE) lichaza i-voltage sag njengokwehla ngokukhawuleza kwexabiso elisebenzayo lombane wobonelelo ukuya kuma-90% ukuya kwi-10% yexabiso elilinganisiweyo.%, kwaye emva koko unyuke umva ukuya kufutshane nexabiso eliqhelekileyo, ubude bexesha yi-10ms~1min.Nje ukuba kubekho i-voltage sag, iya kuzisa umonakalo omkhulu kushishino.Ngenxa yokuba i-voltage sag ithathwa njengeyona ngxaki inobungozi bomgangatho wamandla kwimveliso yamashishini.
Ngokubanzi, i-voltage sag iya kuchaphazela zonke izixhobo zombane eziqhagamshelwe kwisekethe.Ngokukodwa kumashishini okuvelisa kunye nokucubungula afuna ukuchaneka okuphezulu, nje ukuba i-voltage sag idibene, iya kubangela ilahleko ngokulula kunye nenkcitho yeemveliso ezichanekileyo.Okubaluleke ngakumbi, kukhokelela kwisixa esikhulu semathiriyeli ekrwada ukuba ingasetyenziswa.Kwakhona yingozi enkulu kubomi bezixhobo zombane.Ngexesha elifanayo, i-voltage sag iya kubangela inani elikhulu le-harmonics.
Uninzi lwamashishini ngoku asebenzisa izixhobo ezizisebenzelayo okanye ezizisebenzelayo.I-voltage sag inokukhokelela ekugwetyweni kakubi kwezixhobo ezizenzekelayo okanye ezizenzekelayo.Nokuba ibangele unqumamo okanye ukungasebenzi kakuhle.Zonke zinokubangela ukuba isiguquli samaza ukuba sime, kwaye kubangele ukuba izixhobo ezahlukeneyo zokukhusela amandla ombane ziqalise.Kukho iintlobo ezahlukeneyo zeenjini eziqhelekileyo kubomi bemihla ngemihla.Umzekelo, iilifti kunye neeTV ziya kumiswa kwaye zibangele ukuba imoto iqale kwakhona ngequbuliso.
Xa ezi zixhobo zombane zingakwazi ukusebenza ngokuqhelekileyo, ngenxa yenzeke ngokukhawuleza, umgca wokuvelisa wonke uya kuphazamiseka.Xa sifuna ukubuyiselwa okucwangcisiweyo kwawo wonke umgca wemveliso.Ilingana nokunyusa iindleko zexesha kunye neendleko zabasebenzi ngelize.Ngokukodwa kwezo ndawo zineemfuno ngomhla wokuhanjiswa kunye nokuveliswa.
Iya kuba nayiphi impembelelo kubomi bemihla ngemihla?Eyona mvakalelo intuitive kukuba iyakwenza ingozi kwinkqubo yekhompyuter, nto leyo eya kubangela ukuvalwa kunye nokulahleka kwedatha ngokulula (ikhompyuter iya kuvala ngokuthe ngqo, akukhathaliseki nokuba mangaphi amagama othe wawabhala wawalungisa, kuya kuba mva kakhulu ukuba ungawagcina. ngenxa yokuvalwa ngesiquphe).Ngokukodwa ezo ndawo zibaluleke kakhulu, ezifana nezixhobo zesibhedlele, inkqubo yomyalelo wezithuthi njalo njalo.Umzekelo olula kakhulu.Igumbi lotyando kwesi sibhedlele lityandwa.Ukuba kukho i-voltage sag, nokuba sisibane esingenamthunzi okanye ezinye izixhobo eziyinkimbinkimbi kakhulu, xa sele icinyiwe kwaye iqaliswe kwakhona, iya kuba nefuthe elikhulu ekusebenzeni.Olu hlobo lokusilela okubangelwa yingozi yesixhobo alumkelekanga kuwo wonke umntu.
Kubalawuli be-elektroniki befriji, nje ukuba i-voltage sag yenzeke, umlawuli uya kunqumla i-motor yefriji.Kushishino lokwenziwa kweetshiphu, xa amandla ombane engaphantsi kwama-85%, kuya kubangela ukuba isekethe yombane ingasebenzi kakuhle.
Isixhobo solawulo lwe-voltage ye-sag yeshishini elibuthathaka esiveliswe yi-Hongyan Electric sinokusombulula ngempumelelo uthotho lweziphumo ezibangwe yi-voltage sag.Uluhlu lwe-HY lwezixhobo zokulawula amandla ombane we-sag-imveliso ephezulu: ukuthembeka okuphezulu, eyilelwe ngokukodwa imithwalo yemizi-mveliso, ukusebenza kakuhle kwenkqubo, impendulo ekhawulezayo, ukusebenza okuphezulu kokuhlaziya, akukho naliti ye-harmonic, idijithali epheleleyo esekwe kwitekhnoloji yoLawulo lwe-DSP, ukuthembeka okuphezulu, ukuhambelana okuphezulu. umsebenzi wokwandisa, uyilo lwemodyuli, imisebenzi emininzi enegraphic TFT yokwenyani yokubonisa umbala.
