Kwimeko yemizi-mveliso yanamhlanje, imisebenzi engahambelaniyo yomthwalo kwintsimbi, i-petrochemical, i-metallurgy, amalahle, ukuprinta kunye nokudaya kunye namanye amashishini ahlala evelisa inani elikhulu le-harmonics.Ezi harmonics zidityaniswa nomba wamandla aphantsi ziya kubangela ungcoliseko olumandla kwinkqubo yamandla kwaye ekugqibeleni zichaphazele umgangatho wobonelelo lwamandla.Ukujongana nale mingeni,izihluzi eziphezulu ze-voltage passivebaye baba sisisombululo esiphambili, ukubonelela ngembuyekezo ebanzi kunye nezakhono zokucoca ukuphucula umgangatho wamandla kunye nokuthembeka kwenkqubo.
Isixhobo esipheleleyo sembuyekezo ye-voltage passive yembuyekezo yesihluzi ikakhulu siqulathe ii-capacitors zokucoca, izihluzi ze-reactors kunye ne-high-pass resistors, ethi kunye yenze ukulungiswa okukodwa okanye umjelo wokucoca ophezulu.Olu lungelelwaniso lwenza isixhobo ukuba sinciphise ngokufanelekileyo iiharmonics ezithile kunye nee-harmonics ngaphezulu komyalelo othile, ngokubonelela ngeziphumo ezibalulekileyo zokucoca.Ukongeza, inkqubo iphinda yenza imbuyekezo yamandla asebenzayo, ngaloo ndlela iphucula amandla enkqubo kunye nokuphucula ukuzinza kwamandla ombane.Le ndlela ibanzi iqinisekisa ukhuseleko nokuthembeka kwenkqubo yonikezelo lombane, iyenza ibe yi-asethi eyimfuneko kumashishini ajongana nemiba yobulunga bamandla.
Enye yeenzuzo eziphambili zeizihluzi zombane eziphezulu zombaneluqoqosho kunye nokufumaneka kwabo.Ngesakhiwo esilula, ukusebenza okuthembekileyo kunye nokugcinwa lula, lukhetho lokuqala kwiinkqubo zoxinzelelo oluphezulu.Oku akugxininisi kuphela ukusebenza kwazo kodwa kunye nokufaneleka kwazo kwizicelo ezahlukeneyo zemizi-mveliso.Ngokusombulula imiba ye-harmonic kunye ne-power factor, ezi zihluzo zidlala indima ephambili ekwandiseni umgangatho wamandla kunye nokuqinisekisa ukusebenza okungaphazamisekiyo kweenkqubo ezibalulekileyo zamashishini.
Kwintsimbi, petrochemical, metallurgy, amalahle, ukuprinta kunye nokudaya kunye namanye amashishini, ukusasazwaizihluzi eziphezulu ze-voltage passiveuzuze iingenelo ezibalulekileyo.Ngokucoca ngokufanelekileyo ii-harmonics kunye nokuphucula amandla, ezi zihluzo zinceda ukunciphisa kakhulu ungcoliseko lwenkqubo yamandla.Oku kuphucula umgangatho wonikezelo lwamandla, kuvumela la mashishini ukuba asebenze ngobuchule obukhulu kunye nokuthembeka.Impembelelo entle yeizihluzi zombane eziphezulu zombanekula mashishini kuqaqambisa ixabiso lawo njengotyalo-mali olucwangcisiweyo kumashishini ajonge ukwandisa iziseko zawo zamandla.
Ukusasaza izihluzi ze-high-voltage passiv yindlela esebenzayo yokusombulula imiceli mngeni yomgangatho wamandla kwiindawo zemizi-mveliso.Ngokudibanisa izakhono zokucoca eziphambili kunye nembuyekezo yamandla asebenzayo, ezi zixhobo zibonelela ngesisombululo esibanzi sokunciphisa i-harmonic kunye nokuphuculwa kwezinto zamandla.Ukuphumelela kwabo kwezoqoqosho, kunye nokusebenza okuqinisekisiweyo kwizicelo ezahlukeneyo zemizi-mveliso, kubenza babe yi-asethi ephambili kumashishini ajonge ukuphucula umgangatho wobonelelo lwamandla kunye nokuqinisekisa ukusebenza ngokungenamthungo kweenkqubo ezibalulekileyo.Njengoko amashishini eqhubeka nokubeka phambili umgangatho wamandla kunye nokuthembeka kwenkqubo,izihluzi eziphezulu ze-voltage passivezigqame njengezithembekileyo, izisombululo ezisebenzayo ukuhlangabezana nezi mfuno ziphuhlayo.
