Emkhakheni wezinhlelo zegridi yamandla, ukugcina ibhalansi nokuzinza kubalulekile ukuze kuqinisekiswe ukusebenza kahle nangempumelelo.Ingxenye ebalulekile edlala indima ebalulekile ekuzuzeni le bhalansi yidamping resistor box.Lo mshini obalulekile uklanyelwe ukuvimbela ukungalingani kwephoyinti okungathathi hlangothi kwesistimu yegridi yamandla okubangelwa okokufaka nokukalwa kwekhoyili yokucindezela i-arc phakathi nokusebenza okuvamile.
Uma igridi yamandla isebenza ngokujwayelekile, ikhoyili yokucindezela i-arc yesinxephezelo elungiswe kusengaphambili isebenza ukwehlisa ukukhuphuka kwamandla kagesi.Kodwa-ke, ngalesi sikhathi, i-inductance kanye ne-capacitive reactance yekhoyili yokucindezela i-arc cishe ilingana, okuzokwenza ukuthi igridi yamandla ibe sesimweni esiseduze ne-resonance.Lokhu kuphinde kuholele ekwenyukeni kwe-voltage yephoyinti emaphakathi, okungase kuphazamise ukusebenza okuvamile kwenethiwekhi yokuhlinzeka.
Ukuze kuliwe nalesi simo, isisetshenziswa se-resistor esimanzi sihlanganiswa nedivaysi yesinxephezelo yekhoyili ye-arc elungiswe ngaphambilini.Umthelela walokhu okungeziwe uwukucindezela i-voltage yokugudluka yephoyinti eliphakathi nendawo, ukuqinisekisa ukuthi indawo emaphakathi ihlala isendaweni efanele edingekayo ukuze igridi isebenze kahle, iphephile.
Umsebenzi webhokisi le-resistor elimanzi ukuhlinzeka ukumelana okudingekayo ukuze kuncishiswe umthelela we-resonance nokugcina ibhalansi yesistimu yegridi yamandla.Ukwenza kanjalo kusiza ukuvimbela ukuphazamiseka okungenzeka futhi kuqinisekisa ukuzinza okuphelele kwenethiwekhi yokuphakelwa kwamandla.
Empeleni, ibhokisi lokumelana nokuthomalalisa lidlala indima yokuvikela futhi lixazulula ngempumelelo izinselele ezibangelwa ukusebenzisana phakathi kwekhoyili yokucindezela i-arc kanye nesistimu yegridi yamandla.Ikhono layo lokucindezela amashifu kagesi kanye nokugcina indawo emaphakathi emazingeni adingekayo lisiza ukugcina ubuqotho bokusebenza kwegridi.
Kafushane, ukuhlanganiswa kwamabhokisi okumelana nokumanzisa ohlelweni lwegridi kuyisici esibalulekile sokuqinisekisa ukuzinza nokulinganisela.Ngokuqonda indima yabo ekwehliseni imithelela ye-resonance nokugcina i-voltage yamaphuzu amaphakathi, singaqonda ukubaluleka kwawo ekusekeleni ukusebenza okungenazihibe kwamanethiwekhi okuphakela amandla.
