Gqibezela iiseti zolawulo lwesigabaIikhoyili zokucinezela i-arc ziyinxalenye ebalulekileyo yothungelwano lokuhambisa amandla.Esi sixhobo, esaziwa ngokuba yi "high short-circuit impedance type", sidlala indima ebalulekileyo ekuqinisekiseni ukuhanjiswa okusebenzayo nokukhuselekileyo kwamandla ombane.Kule bhlog, siza kujongisisa imigaqo yesakhiwo sale khoyili kunye nokubaluleka kwayo ekuphuculeni iinkqubo zokuhambisa amandla.
Iikhoyili zokucinezelwa kwe-arc ezilawulwa kwisigaba ziyilwe kunye ne-primary winding edibeneyo kwindawo engathathi hlangothi yothungelwano lokuhambisa.Olu jiko luphambili lusebenza njengokujija okusebenzayo.Ukongezelela, isixhobo esipheleleyo siquka i-winding yesibini, esebenza njengolawulo lokulawula.I-winging control winding ixhunywe ngasemva kwi-thyristors ezimbini, ukudala isiphaluka esifutshane.Olu lungelelwaniso luvumela ukulawulwa ngokuchanekileyo kwe-short-circuit current kwi-winding yesibini ngokuxhaphaza i-capacitor.
Enye yeenzuzo eziphambili zeekhoyili zokunciphisa i-arc ezilawulwa yisigaba kukukwazi kwabo ukucinezela ngokufanelekileyo ii-arcs kunye nokuphucula umgangatho wokusasazwa kwamandla.Iimpawu zayo eziphezulu ze-impedance ze-short-circuit impedance ziqinisekisa ukuba iimpazamo ze-arc ezinobungozi zilawulwa ngokufanelekileyo, ukunciphisa umngcipheko womlilo wombane kunye nokunciphisa umonakalo wezixhobo.Ngokubonelela ngokucinezelwa kwe-arc esebenzayo, i-coil inceda ukugcina ukuzinza kunye nokuthembeka kwenkqubo.
Ukongezelela, amandla okulungelelaniswa okuguquguqukayo kwe-winging yokulawula yenza imbuyekezo esebenzayo yamandla asebenzayo.Le ntlawulo yembuyekezo ayiphuculi nje ukuzinza kwamandla ombane, kodwa ikwakhulisa amandla ombane kwaye iqinisekisa ukusetyenziswa ngokufanelekileyo kwamandla ombane.Ngokuphucula ukusebenza kakuhle kokuhanjiswa kwamandla, iikhoyili zokucinezelwa kwe-arc zinceda ukunciphisa ukulahleka kwamandla kunye neendleko zokusebenza ngokubanzi.
Ukhuseleko lwamanethiwekhi okusasazwa kwamandla lubaluleke kakhulu, kwaye ukuyila kweekhoyili zokucinezelwa kwe-arc kubeka phambili ukhuseleko lwezixhobo kunye nabasebenzi.Izakhono zokucima i-arc zekhoyili zinciphisa kakhulu umngcipheko wokuqhuma kunye nokungaphumeleli kwezixhobo ngenxa yeempazamo ze-arc.Ngokufumanisa ngokukhawuleza kunye nokucinezela iimpazamo ze-arc, i-coil yandisa ukuchasana kwenkqubo kwiimpazamo zangaphandle, iqinisekisa indawo ekhuselekileyo yokusebenza kubaqhubi.
Ukongezelela, inkqubo yolawulo oluphambili lwe-coil yokunciphisa i-arc elawulwa yisigaba yenza ukuba uphendule ngokukhawuleza kwiimeko eziphosakeleyo.Iinkqubo zokulawula ezisekelwe kwi-Thyristor ziququzelela ulawulo oluguquguqukayo olukhawulezayo kwaye lunokulungelelanisa ngokukhawuleza ukutshintsha iimeko zomthwalo.Ukukwazi kwekhoyili ukucinezela ngokufanelekileyo iimpazamo ze-arc kunye nokunciphisa i-fault currents ephezulu yongeza ukuthembeka okongezelelweyo kwinethiwekhi yokusabalalisa, ukunciphisa ixesha lokunciphisa kunye nokuphucula ukusebenza kwenkqubo.
Iiseti ezipheleleyo zeekhoyili zokucinezelwa kwe-arc ezilawulwa ngesigaba zisetyenziswa ngokubanzi kumashishini ahlukeneyo afana nokuvelisa amandla, izityalo zoshishino, kunye nezakhiwo zorhwebo.Uluhlu lwayo olubanzi lweenzuzo, kubandakanywa ukuphuculwa kokuhanjiswa kwamandla, ukhuseleko oluphuculweyo kunye nokuthembeka, kuyenza ibe yinto eyimfuneko kwiinkqubo zombane zanamhlanje.
Isishwankathelo, iikhoyili zokunciphisa i-arc ezilawulwa yisigaba ziyinxalenye ebalulekileyo yokusabalalisa amandla ngokufanelekileyo.Imithetho-siseko yayo eqinileyo, kunye neendlela zokulawula eziphambili, ziqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo kwegridi yamandla.Ngokucinezela ngokufanelekileyo iimpazamo ze-arc kunye nokwandisa ukusebenza kakuhle kokuhanjiswa kwamandla, i-coil idlala indima ebalulekileyo ekufezekiseni unikezelo lwamandla olugudileyo kunye olusebenzayo, lunceda imboni kunye nabasebenzisi bokugqibela.
