Qedela amasethi okulawulwa kwesigabaamakhoyili okucindezela i-arc ayingxenye ebalulekile yenethiwekhi yokusabalalisa amandla.Le divayisi, eyaziwa nangokuthi "uhlobo lwe-high short-circuit impedance", idlala indima ebalulekile ekuqinisekiseni ukusatshalaliswa okusebenzayo nokuphephile kwamandla kagesi.Kule bhulogi, sizobhekisisa izimiso zesakhiwo sale khoyili kanye nokubaluleka kwayo ekuthuthukiseni izinhlelo zokusabalalisa amandla.
Amakhoyili okucindezela ama-arc alawulwa yisigaba aklanywe ngendlela eyinhloko exhunywe endaweni emaphakathi yenethiwekhi yokusabalalisa.Lolu hlelo lokusebenza lusebenza njengohlelo lokusebenza.Ngaphezu kwalokho, yonke idivayisi ihlanganisa ukuvuthwa kwesibili, okusebenza njenge-control winding.I-control winding ixhunywe ngokuphambene nama-thyristors amabili, idala isifunda esifushane.Lokhu kulungiselelwa kuvumela ukulawulwa okunembile kwe-short-circuit current kumajika esibili ngokulawula i-capacitor.
Enye yezinzuzo ezibalulekile zamakhoyili okucindezela i-arc alawulwa yisigaba amandla awo okucindezela ngempumelelo ama-arcs kanye nokuthuthukisa ikhwalithi yokusabalalisa amandla.Izici zayo eziphakeme ze-short-circuit impedance ziqinisekisa ukuthi amaphutha e-arc ayingozi alawulwa ngokuphumelelayo, anciphisa ingozi yomlilo kagesi futhi anciphise umonakalo wemishini.Ngokunikeza ukucindezelwa kwe-arc okusebenzayo, ikhoyili isiza ukugcina ukuqina nokuthembeka kwesistimu.
Ngaphezu kwalokho, amandla okulungisa okuguquguqukayo okujikajika kokulawula anika amandla isinxephezelo esisebenzayo samandla asebenzayo.Leli khono lesinxephezelo aligcini nje ngokuthuthukisa ukuzinza kwe-voltage, kodwa futhi lithuthukisa isici samandla futhi liqinisekise ukusetshenziswa kahle kwamandla kagesi.Ngokwenza ngcono ukusebenza kahle kokusabalalisa amandla, amakhoyili okucindezela ama-arc ngezigaba asiza ukunciphisa ukulahleka kwamandla kanye nezindleko zokusebenza zizonke.
Ukuphepha kwamanethiwekhi okusabalalisa amandla kubaluleke kakhulu, futhi ukuklanywa kwamakhoyili okucindezela ama-arc ahlukaniswe ngezigaba kubeka phambili ukuvikelwa kwezinto zokusebenza nabasebenzi.Amandla okucima i-arc ekhoyili anciphisa kakhulu ingozi yokuqhuma kanye nokwehluleka kwemishini ngenxa yamaphutha e-arc.Ngokuthola ngokushesha futhi ucindezele amaphutha e-arc, ikhoyili inyusa ukumelana nesistimu kumaphutha angaphandle, iqinisekisa indawo yokusebenza ephephile kubaqhubi.
Ukwengeza, indlela yokulawula ethuthukisiwe yekhoyili yokucindezela i-arc elawulwa yisigaba yenza impendulo esheshayo ezimweni zephutha.Amasistimu okulawula asuselwa ku-Thyristor enza kube lula ukulawula okuguquguqukayo kwesivinini esikhulu futhi angalungisa ngokushesha ukushintsha izimo zomthwalo.Ikhono lekhoyili lokucindezela ngempumelelo amaphutha e-arc kanye nokunciphisa amandla aphezulu anezela ukwethembeka okwengeziwe kunethiwekhi yokusabalalisa, ukunciphisa isikhathi sokuphumula nokuthuthukisa ukusebenza kwesistimu.
Amasethi aphelele amakhoyili okucindezela i-arc alawulwa ngesigaba asetshenziswa kakhulu ezimbonini ezihlukahlukene ezifana nokuphehla ugesi, izitshalo zezimboni, nezakhiwo zezentengiselwano.Izinhlobonhlobo zezinzuzo zayo, okuhlanganisa ukusebenza kahle kokusabalalisa amandla okuthuthukisiwe, ukuphepha okuthuthukisiwe nokwethembeka, kuyenza ibe ingxenye ebalulekile ezinhlelweni zikagesi zesimanje.
Kafushane, amakhoyili okucindezela i-arc alawulwa ngesigaba ayizingxenye ezibalulekile zokusabalalisa amandla okuphumelelayo.Izimiso zayo eziqinile zesakhiwo, ezihambisana nezindlela zokulawula ezithuthukisiwe, ziqinisekisa ukusebenza okuphephile nokuthembekile kwegridi yamandla.Ngokucindezela ngempumelelo amaphutha e-arc kanye nokwandisa ukusebenza kahle kokusabalalisa amandla, ikhoyili idlala indima ebalulekile ekutholeni ukuphakelwa kukagesi okushelelayo nokusebenza kahle, kuzuzisa imboni kanye nabasebenzisi bokugcina.
