Kwihlabathi lanamhlanje, iinkqubo zokuhambisa amandla zidlala indima ebalulekileyo kwaye ziqinisekisa ukhuseleko kunye nokuthembeka kombane kubalulekile.Ukoyisa iingxaki ezinxulumene ne-arcing, imveliso eguqukayo - iiseti ezipheleleyo zeiikhoyili zokucinezela arc ngezigaba– yaphuhliswa.Kule bhlog, siza kugocagoca kwinkcazo yemveliso yesi sisombululo sintsha kwaye sijonge ukuba siluphucula njani ukhuseleko lokuhanjiswa kwamandla.
Iikhoyili zokucinezelwa kwe-arc zivame ukubizwa ngokuba "uhlobo lwe-impedance ye-short-short-circuit" kwaye yongezwa okubalulekileyo kwinethiwekhi yokusabalalisa.Ngokungafaniyo neekhoyili zokucinezelwa kwe-arc eziqhelekileyo, esi sisombululo siphambili sisebenzisa i-winging ephambili eqhagamshelwe kwindawo engathathi hlangothi yothungelwano lokuhambisa njenge-winding yokusebenza.Ngexesha elifanayo, ukuvuthwa kwesibini kusetyenziswa njengolawulo olujikelezayo kwaye lubandakanya i-thyristors edibeneyo edibeneyo kwiinjongo zesekethe ezimfutshane.Ngokulungelelanisa i-angle conduction ye-thyristor, i-short-circuit current ye-second winding inokulungiswa ngokufanelekileyo.
Isethi yonke yeekhoyili zokunciphisa i-arc ezilawulwa yisigaba zineenzuzo ezininzi kwaye zinceda kakhulu ekuphuculeni ukhuseleko lokusabalalisa amandla.Okokuqala, i-impedance yayo ephezulu ye-short-circuit iphazamisa i-arc ngokukhawuleza, ukunciphisa umngcipheko weengozi zombane kunye nomonakalo wezixhobo.Okwesibini, ulawulo oluchanekileyo lwangoku lwe-short-circuit current lunika ukhuseleko oluphezulu kwizixhobo ezibuthathaka, ngaloo ndlela ukwandisa ukusebenza kakuhle kunye nokunciphisa ixesha lokuphumla.Ukongeza, ukusetyenziswa kombane ngokufanelekileyo kwenza kube lula ukulawula ukusetyenziswa kwamandla, okukhokelela ekongiweni kweendleko kubasebenzisi bombane.
Iikhoyili zokucinezelwa kwe-arc ezisezantsi zidlala indima ebalulekileyo kuluhlu olubanzi lweenkqubo zokuhambisa amandla.Oku kubandakanya izikhululo zamandla ombane aphezulu, iiplanti zemizi-mveliso, izakhiwo zorhwebo kunye neendawo zokuhlala.Ngokucinezela ngokufanelekileyo ii-arcs, iteknoloji iqinisekisa ukunikezelwa kwamandla okuthembekileyo kunye nokukhuselekileyo, ukuthintela ukudibanisa kwamandla ombane, ukuphazamiseka okukhulu kunye nomlilo wombane.Ukusetyenziswa kwayo kwiinkqubo zokuhambisa amandla kubeka imigangatho emitsha yokhuseleko kwaye ihlangabezana neemfuno ezikhulayo zabasebenzisi bamandla banamhlanje.
Iseti epheleleyo yeekhoyili zokucinezelwa kwe-arc ezilawulwa yisigaba inokuthembeka okugqwesileyo kunye nokuphila ixesha elide.Imveliso iyilwe kwaye yakhiwe phantsi kwamanyathelo okulawula umgangatho ongqongqo ukuze kuqinisekiswe ukusebenza okuphezulu nakwiimeko ezibuhlungu zokusingqongileyo.Ukwakhiwa kwayo okudibeneyo kunye nokuqina kuvumela ukufakwa lula kwaye kuyahambelana neziseko zokuhambisa amandla ezikhoyo.Ukongezelela, ukugcinwa rhoqo kunye nokuhlolwa rhoqo kunceda ukwandisa ubomi bemveliso kunye nokwandisa izibonelelo ezizisa kubasebenzisi bombane kunye nabaqhubi benethiwekhi.
Njengoko ubomi bethu bemihla ngemihla buxhomekeke ngakumbi kumbane, ukuqinisekisa ukuba inkqubo yokuhanjiswa kwamandla ekhuselekileyo nethembekileyo kubalulekile.Iseti epheleleyo yeekhoyili zokunciphisa i-arc yisisombululo esitsha esiphucula ukhuseleko, ukuthembeka kunye nokusebenza kakuhle.Ngokucinezela ngokufanelekileyo ii-arcs, kunciphisa umngcipheko weengozi, ukungaphumeleli kwezixhobo kunye nexesha lokunciphisa iindleko.Ukusebenzisa le teknoloji kwiinkqubo zokusasaza kusisondeza ekufezekiseni ikamva lamandla elikhuselekileyo nelizinzileyo.
