Amasistimu egridi kagesi awumgogodla wezwe lanamuhla, ahlinzeka ngamandla ezindlini, ezimbonini nakho konke okuphakathi.Kodwa-ke, ukugcina amandla kagesi azinzile futhi alinganiselayo ohlelweni lwegridi yamandla akuwona umsebenzi olula, ikakhulukazi lapho ubhekana nezindaba ezinjengokungalingani kwephoyinti kagesi.Yilapho umguquliIbhokisi Lokumelanakungene ukudlala.Amabhokisi e-resistor aklanyelwe ukuvimbela ukungalingani kwamandla kagesi okubangelwa ukufakwa nokukalwa kwamakhoyili okucindezela i-arc futhi ayisixazululo sokuqinisekisa ukusebenza kahle kwegridi yamandla.
Ngaphansi kwezimo ezivamile zegridi yamandla, ikhoyili yokucindezela i-arc yesinxephezelo elungiswe kusengaphambili ibalulekile ekugcineni ukuqina kwamandla kagesi.Kodwa-ke, lapho le khoyili isebenza, iletha izinselele ezithile, njengokwenyuka kwamandla kagesi aphakathi nendawo angalingani.Ukuze kuxazululwe le nkinga, kwenziwa ucwaningo olunzulu nokuklama, okwaphumela ekudalweni kwebhokisi lokumelana elihlakaniphile.Ivumela i-inductance ye-arc suppression coil ukuthi ilungiswe ngaphambili ukuze kuqinisekiswe ukuthi ikhoyili isebenza ngendlela efanele ngesikhathi sokusebenza okujwayelekile.
I-inductance kanye ne-capacitive reactance idlala indima ebalulekile ekugcineni ibhalansi kagesi kumasistimu egridi yamandla.Ibhokisi lokumelana liqinisekisa ukuthi lezi zici zilinganiswa ngokucophelela ukuze kusebenze kahle ikhoyili yokucindezela i-arc.Ngokunciphisa inkinga yama-voltage angalingani endaweni engathathi hlangothi, amabhokisi aphikisayo agcina igridi isebenza kahle, ehlinzeka ngokuphakelwa kwamandla okungaphazamiseki ezindlini, amabhizinisi nengqalasizinda ebalulekile.
Enye yezinzuzo eziyinhloko zamabhokisi e-resistor yikhono lawo lokuthuthukisa ukuqina kwegridi ngaphandle kokuphazamisa ukusebenza okuvamile kwesistimu yamandla.Ngokulungisa kusengaphambili i-inductance yekhoyili yokucindezela i-arc, isidingo sokulungiswa kwamandla asebenzayo ngesikhathi sokusebenza okuvamile kwegridi siyancishiswa.Lokhu akunciphisi nje kuphela izindleko zokulungisa kodwa futhi kuthuthukisa ukusebenza kahle jikelele kwegridi, ngaleyo ndlela kuthuthukisa ukwethembeka kubathengi.Ibhokisi Lokuphikisa ngempela lishintsha umdlalo uma kuziwa ekuzinzeni kwegridi.
Ukwengeza, ibhokisi lokumelana lenzelwe ukufakwa nokusebenza kalula.Ukusebenzelana kwayo okusebenziseka kalula nezilawuli ezinembile kwenza kube lula ukuthi ama-opharetha wegridi nochwepheshe basebenzise, okwenza kube lula inqubo yokuthuthukisa ukuqina kwegridi.Ngobuchwepheshe obuthuthukisiwe kanye nomklamo ogxile kubasebenzisi, amabhokisi okumelana ahlinzeka ngesixazululo esisebenzayo sokugcina ibhalansi yamandla kagesi angathathi hlangothi, okuqinisekisa ukwethembeka nokusebenza kahle kwegridi yamandla.
Kafushane, i-Resistor Box iwumkhiqizo ophumelelayo oxazulula inselele yokugcina ukuqina kwamandla kagesi wegridi.Ngokulungisa kusengaphambili i-inductance yekhoyili yokucindezela i-arc, inkinga yokungalingani kwe-voltage yephoyinti engathathi hlangothi iyancishiswa futhi ukusebenza kahle kwesistimu yegridi yamandla kuyaqinisekiswa.Idizayini yayo esebenziseka kalula kanye nezici ezithuthukisa ukusebenza kahle kwayo kuyenza ibe ithuluzi elibalulekile labasebenzisa igridi nochwepheshe.Ngamabhokisi aphikisayo singathuthukisa ukuzinza kwegridi futhi sinikeze amandla angaphazamiseki ukuhlangabezana nezidingo ezihlala zikhula zomhlaba wesimanje.
