Kwintsimi yeenkqubo zegridi zamandla, ukugcina ibhalansi kunye nokuzinza kubalulekile ekuqinisekiseni ukusebenza kakuhle kunye nokusebenza kakuhle.Icandelo eliphambili elidlala indima ebalulekileyo ekuphumezeni olu lungelelwaniso yiibhokisi yokumelana nokumanzisa.Esi sixhobo esibalulekileyo senzelwe ukuthintela ukungalingani kwamanqaku okungathathi hlangothi kwenkqubo yegridi yamandla okubangelwa igalelo kunye nomlinganiselo we-arc yokunciphisa ikhoyili ngexesha lokusebenza okuqhelekileyo.
Xa igridi yamandla isebenza ngokuqhelekileyo, i-coil yokunciphisa i-arc yembuyekezo elungiselelwe kwangaphambili isebenza ukucotha ukunyuka kombane.Nangona kunjalo, ngeli xesha, i-inductance kunye ne-capacitive reactance ye-arc suppression coil iphantse ilingane, eya kubangela ukuba igridi yamandla ibe kwimeko ekufutshane ne-resonance.Oku kukhokelela ekunyuseni kwe-voltage ye-neutral point, enokuthi iphazamise ukusebenza okuqhelekileyo kwenethiwekhi yokubonelela.
Ukuze uchase le nto, isixhobo sokumelana nokumanzi sidityaniswe kwisixhobo sembuyekezo ye-arc yokucinezelwa kwangaphambili.Umphumo wolu longezelelo kukucinezela i-voltage yokufuduka yendawo engathathi hlangothi, ukuqinisekisa ukuba indawo engathathi hlangothi ihlala kwindawo efanelekileyo efunekayo ukuze usebenze kakuhle, ngokukhuselekileyo kwegridi.
Umsebenzi webhokisi elichasayo le-damping kukubonelela ukuchasana okuyimfuneko ukunciphisa impembelelo ye-resonance kunye nokugcina ukulingana kwenkqubo yegridi yamandla.Ukwenza oko kunceda ukuthintela ukuphazamiseka okunokwenzeka kunye nokuqinisekisa ukuzinza ngokubanzi kwenethiwekhi yonikezelo lwamandla.
Eyona nto ibalulekileyo, ibhokisi yokuchasa i-damping idlala indima yokukhusela kwaye isombulule ngokufanelekileyo imingeni ebangelwa ukusebenzisana phakathi kwe-coil yokunciphisa i-arc kunye nenkqubo yegridi yamandla.Ukukwazi kwayo ukucinezela iinguqu ze-voltage kunye nokugcina indawo engathathi hlangothi kumanqanaba afunekayo kunceda ukugcina ingqibelelo yokusebenza kwegridi.
Isishwankathelo, ukuhlanganiswa kweebhokisi ze-resistor zokumanzisa kwinkqubo yegridi yinto ephambili yokuqinisekisa ukuzinza kunye nokulinganisela.Ngokuqonda indima yabo ekudambiseni iziphumo zeresonance kunye nokugcina amandla ombane angathathi hlangothi, sinokuqonda ukubaluleka kwabo ekuxhaseni ukusebenza ngokungenamthungo kothungelwano lonikezelo lwamandla.
