Ezweni lanamuhla, izinhlelo zokusabalalisa amandla zidlala indima ebalulekile futhi ziqinisekisa ukuphepha nokwethembeka kukagesi kubalulekile.Ukuze unqobe izinkinga ezihlobene ne-arcing, umkhiqizo wokuguqula - amasethi aphelele weamakhoyili okucindezela ama-arc anezigaba– yathuthukiswa.Kule bhulogi, sizokwehla encazelweni yomkhiqizo yalesi sixazululo esisha futhi sihlole ukuthi kuthuthukisa kanjani ukuphepha kwamandla.
Amakhoyili okucindezela ama-arc ngezigaba ngokuvamile abizwa ngokuthi “uhlobo lwe-high short-circuit impedance” futhi ayisengezo esibalulekile kunethiwekhi yokusabalalisa.Ngokungafani namakhoyili avamile okucindezela i-arc, lesi sixazululo esithuthukisiwe sisebenzisa i-winging eyinhloko exhunywe endaweni engathathi hlangothi yenethiwekhi yokusabalalisa njengendlela yokusebenza.Ngesikhathi esifanayo, ukujika kwesibili kwesibili kusetshenziswa njengendlela yokulawula futhi kuhlanganisa ama-thyristors amabili axhumeke emuva ngezinjongo zesekethe elifushane.Ngokulungisa i-angle conduction ye-thyristor, i-current-circuit current of the second winding ingalungiswa ngempumelelo.
Isethi yonke yamakhoyili okucindezela i-arc alawulwa ngesigaba anezinzuzo eziningi futhi ayasiza kakhulu ekuthuthukiseni ukuphepha kokusabalalisa amandla.Okokuqala, isici sayo esiphezulu se-short-circuit impedance siphazamisa i-arc ngokushesha okukhulu, sinciphise ubungozi bezingozi zikagesi nokulimala kwemishini.Okwesibili, ukulawulwa okunembile kwe-short-circuit current kunikeza isivikelo esiphezulu semishini ebucayi, ngaleyo ndlela kwandise ukusebenza kahle kokusebenza nokunciphisa isikhathi sokuphumula.Ukwengeza, ukusetshenziswa kahle kukagesi kwenza ukuphathwa kangcono kokusetshenziswa kukagesi, okuholela ekongeni kwezindleko kubasebenzisi bakagesi.
I-PASED FRUPRESS CoILS COILS idlala indima ebalulekile ezinhlelweni ezahlukahlukene zokusabalalisa kwamandla.Lokhu kufaka phakathi izinto eziphakeme ze-voltage, izitshalo zezimboni, izakhiwo zentengiso nezindawo zokuhlala.Ngokucindezela ngempumelelo ama-arcs, ubuchwepheshe buqinisekisa ukutholakala kwamandla okuthembekile nokuphephile, ukuvimbela ukucwiliswa kwamandla kagesi okungaba khona, ukuphazamiseka okukhulu ngisho nemililo kagesi.Ukusetshenziswa kwayo ezinhlelweni zokusabalalisa kwamandla kusetha amazinga amasha okuphepha futhi kuhlangabezana nezidingo ezikhulayo zabasebenzisi bamandla banamuhla.
Isethi ephelele yamakhoyili alawulwa ngesigaba se-Arc Supression anokwethenjwa okuhle nokuphila isikhathi eside.Umkhiqizo uklanywe futhi wakhiwe ngaphansi kwezinyathelo eziqinile zokulawula ikhwalithi ukuze kuqinisekiswe ukusebenza okuphakeme ngisho nasezimeni ezinzima zemvelo.Ukwakhiwa kwalo okuqinile nokuqinile kuvumela ukufakwa okulula futhi kuyahambisana nengqalasizinda ekhona yokusabalalisa kwamandla.Ukwengeza, ukunakekelwa okuvamile kanye nokuhlolwa okuvamile kusiza ukwandisa impilo yomkhiqizo futhi kwandise izinzuzo eziletha kubasebenzisi bakagesi kanye nabaqhubi benethiwekhi.
Njengoba izimpilo zethu zansuku zonke zincika kakhulu kugesi, ziqinisekisa uhlelo oluphephile noluthembekile lokusabalalisa amandla lubalulekile.Iqoqo eliphelele lamakhoyili okucindezela ama-arc ahlukaniswe ngezigaba yisixazululo esisha esithuthukisa ukuphepha, ukwethembeka nokusebenza kahle.Ngokucindezela ngempumelelo ama-arcs, kunciphisa ubungozi bezingozi, ukwehluleka kwemishini kanye nesikhathi sokuphumula esibizayo.Ukusebenzisa lobu buchwepheshe ezinhlelweni zokusabalalisa kusisondeza ekuzuzeni ikusasa lamandla elivikeleke kakhulu nelisimeme.
